Study this manual and the manufacturer's manual(s) for your specific machine. Make them a working part of your safety program. Keep in mind that this safety manual is written for vehicle mounted digger derricks. Practice all other usual and customary safe working precautions, and above all-

REMEMBER-SAFETY IS UP TO
YOU
YOU CAN PREVENT SERIOUS INJURY OR DEATH

For Safe Operation

WARNING: For safe operation of this digger derrick, all members of the crew must be trained, qualified and authorized to perform their particular duties.

To be qualified, you must:

• understand the written safety and operating instructions supplied by the manufacturer, company rules, and OSHA regulations;
• have training, including actual operation of this digger derrick;
• be sure the unit is operating properly and has been inspected and maintained according to the manufacturer's manuals;
• be sure that all safety signs, guards and other safety features are in place and in proper condition
• know and follow the safety rules and regulations for the jobsite.

WARNING: Use of this machine by an untrained person can result in severe injury or death.

WARNING: On the job, you and your crew must not use drugs or alcohol; they can impair alertness and coordination. Anyone taking prescription or over-the- counter drugs needs medical advice regarding whether or not they can safely operate machines.

The ground crew member must know how to lower the unit from the lower controls and emergency rescue procedures.

Know The Rules (1)

Most employers have rules governing operation and maintenance of equipment. Before you start work at a new location, check with your supervisor or the safety coordinator. Ask about rules you will be expected to obey.

These are some of the rules you must work by:

• Know the capacity and operating characteristics of this machine, including maximum permitted ground slope.
• Never modify or remove any part of the machine (except for service, reinstall before operating).
• Keep others away from your operation.
• Whenever you leave your machine, always stow auger, attachments and boom in their transport locked position. Engage the parking brake. stop the engine and remove the key. Make sure you understand the rules covering traffic at your jobsite. Know what all signs, flags, and markings mean. Understand hand, flag, horn, whistle, siren, or bell signals. Know when to use lights, turn signals, flashers, and horns.

Know Your Equipment

Digger derricks differ in their operation, capacity, mechanisms, maintenance, intended uses, etc., so your knowledge of one digger derrick may not help you safely operate another.

Know if your digger derrick is rated insulated or non-insulated as meeting the dielectric requirements of the American National Standards Institute (ANSI) in effect at the time of manufacture. The derrick must be manufactured, marked and maintained as an insulated machine. An insulated derrick is ANSI rated for use at 46 kV and below. The ANSI rating is printed on the serial number and capacity placard of your machine. If you do not know the rating of your machine, contact the manufacturer or dealer for a determination.

Know the proper boom deployment to provide dielectric protection. The dielectric rating does not include bridging of the insulating boom section with any winch line. While synthetic winch lines are sometimes described as "non-conducting", it is important to know that dielectric test results are obtained from new and clean rope. Dirt, grease, other foreign matter and moisture—humiditywill reduce the insulating ability of the winch line.

Insulated digger derricks are designed and manufactured for work in which the fiberglass boom section is considered SECONDARY protection for the operator from electrical contact. PRIMARY protection is provided by using protective equipment, maintaining specified distances from energized conductors and following local, state/provincial and federal (OSHA) required safety precautions.

Only fully trained and qualified operators, proficient as electrical linemen and familiar with hazards of energized conductors, may use an insulated derrick near energized conductors.

Work safely

Machine set up

Position Unit For Operation

• Position vehicle on the most level ground, but equipment must not be operated on an incline greater than permitted in the manufacturer's operating manual. If on an incline, position the vehicle so that the boom would be operated on the upgrade side in a stable position.
• Spot your vehicle as close to the work as possible to minimize reach. but be sure there are no obstructions to prevent safe and proper lift and rotation.
• Shift the transmission to neutral.
• Set the parking and holding (if equipped) brakes.
• Set wheel chocks on both sides
• Set the outriggers. Use outrigger pads if the surface is soft. Level the vehicle as much as possible, but observe the manufacturer's maximum ground slope.
• Do not plant outriggers on a curb, stump or projecting boulder. This will reduce outrigger spread and may affect stability.
• Follow the manufacturer's operating manual for instructions on proper setting of the outriggers for your machine.
• Always have outriggers in view when they are being extended, and/or use a signal person to watch.

WARNING: Do not lower the outriggers until all personnel are clear of the area of each outrigger. Setting an outrigger on a person's foot or other body part may cause serious crushing injury. (9)

• Make sure the vehicle is stable

Digger Derrick Safety Precautions

• Make sure the area is clear of all persons before you start operating.
• Never allow the booms or turntable to enter traffic lanes without proper barricading. Park to block traffic. When parking on a street put out traffic barriers to oncoming traffic. As necessary, use a signal person to control traffic.
• Check the clearance overhead. Note any obstructions. Know exactly how much clearance all parts of your digger derrick have around energized power lines.

DANGER: NON-INSULATED machines shall NOT be used on or near any energized power line. Death or serious injury will result from contact with or inadequate clearance to energized power lines or apparatus.

• MAINTAIN SPECIFIED DISTANCE FROM ELECTRICAL LINES AND APPARATUS. Never approach energized power lines with any part of your machine unless all local, state/provincial and federal (OSHA) required safety precautions have been taken. Use extreme caution.
• YOU MUST ALLOW FOR PLATFORM SWAY, ROCK AND CREEP. ALSO ELECTRICAL LINE SWAYING.
• Beware of strong and/or gusty wind conditions.
• Barriers are required when the boom is near energized conductors.
• A machine working near energized conductors MUST ALWAYS BE CONSIDERED ENERGIZED.
• No one is allowed near the machine during operation except the operator. THE OPERATOR MUST REMAIN ON THE MACHINE AT ALL TIMES. (10)
• Always make sure that you follow the manufacturer's recommendations while operating the digger derrick.

Lifting Loads

WARNING: Park on a firm surface before operating the derrick. Always use wheel chocks and parking/holding brakes. Outriggers must be extended as directed in manufacturer's operating manual. Outrigger pads must be used on all unpaved, asphalt or other soft surfaces. (11)

Before Starting

Working load depends on many job conditions (i.e. support surface, slope, wind, hazardous surroundings, operator experience, machine condition and others). The operator must deduct from maximum loads for these factors. Weights of load handling devices, platforms etc. must be considered as a part of the maximum load. Proper deductions must be made from chart loads to obtain allowable loads when these devices are used. If any factors are between values listed on the capacity chart, the lower value must be used.

Read your manufacturer's operation manual before lifting a load. Make sure you are aware of and have received instruction in the location, function and proper use of winch, boom and rotation controls.

Before starting, walk around the equipment. Make sure no one is under, on or close to the unit. Let other workers or bystanders know you are starting up. Don't start until everyone is clear of the unit.

Lifting

Before lifting a load, see the manufacturer's manual or load chart affixed to the boom for the lifting capacity of your machine with the boom in various positions. (12)

Know the rated load of your winch line. Refer to your operators manual for proper use of a multiple part winch line and snatch block with your equipment.

WARNING: Overloading is dangerous. Know the weight you are lifting. If you do not know the weight of the load, you must determine it before lifting.

• Make certain you are within the safe load and work radius limitations of this derrick.
• Make sure you are on solid level ground within manufacturer's maximum slope before lifting any load.
• Never allow anyone to enter the derricks rotation area or walk under the boom or suspended load.
• DO NOT OPERATE the boom or winch function controls from the ground.
• Never allow anyone to ride on the load or load hook.
• Do not operate during high winds or electrical storms.
• Be careful of loose objects falling from the boom when you start up.
• DO NOT make side pulls with the loadline. The boom head must be directly over the load before lifting.
• Check the brake when lifting. Stop the load 3 to 5 feet above the ground and slowly meter the control to lower, and then stop the load.
• Do not allow the loadline block to contact the boom tip by winching up, lowering or extending the boom.
• Rotate the boom slowly so the load does not sway or swing around. Use a tag line, if necessary, for greater control.
• Keep the load as low as possible during rotation.
• Operate all controls slowly and smoothly to avoid shock loads and excessive movement of the load. Lower the load slowly to avoid shock loading of the boom and vehicle.
• Be extremely cautious when lowering or extending the boom while lifting a load. This will have an immediate effect on the load capacity and stability of the derrick. REFER TO THE CAPACITY CHART.
• Be aware of the boom and load location at all times. Have a signal person watch any area blind to the operator. You must maintain a safe distance from overhead wires during lift operations. Allow for boom rise when load is relieved.

DANGER: Maintain clearance as specified in local, State/Provincial, company work rules and Federal (OSHA) rules from energized power lines. Contact with or inadequate clearance from energized conductors will cause DEATH or serious injury to persons in contact with or near the vehicle, load or any extensions of them.

• DO NOT attempt to use the winch to pull a pole that is imbedded in the ground.

Pole  Setting

Your unit may be equipped with a pole guide and boom flares designed to be used along with the winch to set poles. You must follow all of the instructions for load lifting when setting poles. Refer to your manufacturer's operating manual for proper use of the pole guide and boom flares for setting poles. If there is no manual with the machine—get one. Read and understand it before you start work. If there is something in the manual you don't understand, ask your supervisor to explain it to you.

WARNING: Pole guides are for aligning and positioning poles. Severe injury or death can result if pole guides are used for pole lifting or pole pulling operations. Pole weight must be supported at all times by the winch load line. Do not wrap the load line around the pole. Use a lifting sling when lifting the pole to avoid damage to the load line.

WARNING: Park on a firm surface before operating the derrick. Always use wheel chocks and parking/holding brake. Outriggers must be extended as directed in manufacturer's operating manual. Outrigger pads must be used on all unpaved, asphalt or other soft surfaces.

Digging Operations
Before Starting

Read your manufacturer's operation manual before digging. Make sure you are aware of and have received instruction in the location, function and proper use of winch, boom, rotation and auger controls. If there is no manual with the machine—get one. Study it before you start work. If there is something in the manual you don't understand, ask your supervisor to explain it to you.

WARNING: Park on a firm surface before operating the auger. Always use wheel chocks and parking brakes. Outriggers must be extended as directed in manufacturer's operating manual. Outrigger pads must be used on all unpaved, asphalt or other soft surfaces.

WARNING: Inspect the auger windup cable/rope each day. If the cable/rope shows signs of wear replace it immediately. A worn windup cable/rope could fail causing a free swinging auger. A free swinging auger could cause death or serious injury.

WARNING: All personnel must be clear of the area before stowing or unstowing the auger. (13) A free swinging auger can cause death or serious injury.

Digger Operation

Refer to your manufacturers manual for instructions on digger operation.

Position the unit on a level surface, apply the parking brakes and chock the wheels. Engage the PTO and properly set the outriggers.

Unstowing The Auger

Raise and rotate the booms high enough so that when the digger is lowered, it will clear the vehicle, obstacles and all personnel.

DANGER: Maintain clearance as specified in local, State/Provincial, company work rules and Federal (OSHA) rules from energized power lines. Contact with or inadequate clearance from energized conductors can cause DEATH or serious injury to persons in contact with or near the vehicle, load or any extensions of them.

• Make sure digger is in low speed.
• Move the auger control slightly to the clean or dig side (depending on the direction of windup) to relieve the weight from the stow latch.
• Retract the stow latch from under the auger tube.
• Move the auger control to the correct position to slowly unwind and lower the auger.
• When the auger tube has cleared the stow latch, return the control to the locked position.
• When the auger is in the vertical position, remove the windup cable from the auger flight.

Underground Hazards

Before digging—make sure you know the location of all existing underground hazards such as electric lines, gas lines, fiber-optic cables, water lines, sewer lines, pipe lines, tanks or others.

WARNING: Always contact your local One-Call system and any utility companies which do not subscribe to One-Call before the start of your digging project. (See page 5, One-Call First.)

Emergency Procedures

Electrical strike and you are on the digger derrick:

• DO NOT LEAVE the machine. WARN OTHERS that an electrical strike has occurred and to stay away.
• RAISE the digger to break contact.

Electrical strike and you are on the ground:

• STAY where you are and DON'T MOVE.
• DO NOT TOUCH the machine or anything connected with the machine.
• WARN OTHERS that an electrical strike has occurred.

Gas strike procedure

• WARN others that a gas strike has occurred.
• WARN bystanders that a gas strike has occurred and to stay away.
• IMMEDIATELY SHUT OFF engine(s) and remove any ignition sources.
• DO NOT SMOKE or do anything that could cause a spark.
• EVACUATE and SECURE the area.
• CALL or have someone call 911 and other local EMERGENCY NUMBER(S).

Fiber-optic strike procedure

• DO NOT LOOK into the cut ends of a fiber-optic or unidentified cable. A cut fiber-optic cable can cause severe eye injury if you look into the damaged end of the cable.
• WARN OTHERS that a fiber-optic strike has occurred.

Water or sewage strike procedure

• WARN OTHERS that a water or sewage strike has occurred. Sewage may contain pathogens. It may be advisable to seek medical attention for personnel coming in contact with sewage.

In all cases:

• CALL or have someone call 911 or other local EMERGENCY NUMBER(S).
• CALL or have someone call the affected utility and the statewide One-Call System.
• DO NOT RESUME work until the utility has cleared you to do so.

Digging

• Use the intermediate boom extension and rotation controls to position the digger directly over the hole location.
• A moderate steady down force on the digger using the boom control will produce the most efficient digging.
• Be careful not to use excessive down force as this may cause the auger to corkscrew into the ground. If this occurs stop digging and use the clean function to release the auger.
• Use the boom controls to follow the auger into the ground. This is especially true if the auger is positioned at a side angle to the boom.
• Maintain alignment of the hole and the auger shaft.
• Failure to do so can bend the auger or auger extension shaft. If the auger or auger shaft bends, stop digging immediately. A bent auger or shaft must be straightened or replaced immediately.

WARNING: Use extreme caution when stowing or unstowing a bent auger or auger extension shaft. Failure of the digger output shaft, auger extension shaft or auger windup could occur causing a free swinging auger. Death or serious injury could result.

Stowing The Digger

WARNING: All personnel must be clear of the area before stowing or unstowing the auger. A free swinging auger can cause death or serious injury.

• Return the auger extension shaft to its original position if it has been lengthened.
• Fully retract the intermediate boom.
• Make sure the digger speed switch is in the low position.
• Rotate the boom to a position that will allow the boom and auger to clear all obstacles when the digger is stowed.
• Attach the auger windup rope/cable to the auger following the manufacturer's instruction.
• Meter the dig control to the correct position, following your manufacturer's operating instructions, until the auger slowly winds up into the stowed position.
• Refer to your manufacturer's manual for proper operation of the auger latch.

WARNING: Failure to meter the auger control could result in rapid windup of the digger and shock loading when it enters the auger stow bracket. Component failure due to shock loading could cause a free swinging auger. which may cause death or serious injury.

Remote Power Tool Usage

Your digger derrick may be equipped with remote tool outlets to accommodate hydraulic tool accessories. Before connecting or disconnecting a tool to a remote outlet bleed off any hydraulic pressure by turning the pump off and cycling the controls several times. Make sure and keep hydraulic hose connectors clean and dry at all times. Read and follow the manufacturer's instructions for proper use of the tools.

WARNING: Tool circuits may reach very high pressures if a tool is stalled. This could cause bursting or leakage of the hoses or tool. Hydraulic fluid under pressure can penetrate the skin or eyes and cause injury, blindness or death. If any fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury.

DANGER: The booms must not be elevated near energized conductors when operating a lower tool system. Lower tool system hoses may be conductive. If the machine were to become electrically charged, death or serious injury will result.

Pole Puller

The pole puller should be used to break a pole loose from the ground. The winch and boom functions can then be used to remove the pole from the ground.

The pole must be within the machines load capacity and booms must not be raised near energized conductors.

Before using the pole puller, attach the winch line at the top of the pole to support the pole once it is loose in the ground.

WARNING: Use only one wrap of chain around the pole. A "choke" chain could cause the chain to break with great force. A chain flying off the pole could cause serious injury to nearby personnel.

WARNING: Clear all personnel from the area before extending the pole puller cylinder. A falling pole could cause death or serious injury.

When finished using the tool outlet, the circuit pressure should be bled off by stopping the pump and cycling the hydraulic controls several times. The control should be returned to the off position. All hoses and tools must be returned to their stowed position. Wipe up any spilled hydraulic fluid.

Personnel Platform

Your digger derrick may be equipped with a personnel platform mounted on the upper boom. This platform is to be used to position personnel for aerial operations. Follow the manufacturer's instructions contained in the operator's manual for proper deployment of the personnel platform.

WARNING: Insulated machines require that specific configuration, maintenance and boom deployment instructions be followed to maintain the dielectric rating. These instructions are found in the manufacturer's manuals and on decals and signs on the digger derrick. Failure to follow these instructions can lead to serious injury or death in the event of electrical contact.

Read and understand your manufacturer's operation manual before using the platform. Make sure you are aware of and have received instruction in the location, function and proper use of all controls. If there is no manual with the machine—get one. Read and understand it before you start work.

If there is something in the manual you don't understand, ask your supervisor to explain it to you.

WARNING: Park on a firm flat surface before operating the platform. Always use wheel chocks and parking/holding brakes. Outriggers must be extended as directed in manufacturer's operating manual. Outrigger pads must be used on all unpaved, asphalt or other soft surfaces

DANGER: Maintain clearance as specified in local, State/Provincial, company work rules and Federal (OSHA) rules from energized power lines. Contact with or inadequate clearance from energized conductors will cause DEATH or serious injury to persons in contact with or near the vehicle, load or any extensions of them.

Utilities - Overhead

Electrocution can result from contacting or approaching energized overhead power cables. Only INSULATED machines are suitable for this work.

WARNING: No digger derrick, insulated or not, is considered PRIMARY protection for the operator from electrical contact. Use all required protective equipment, maintain specified distance from electrical lines or apparatus and follow all local, state/provincial and federal (OSHA) required safety precautions. Failure to take these precautions can result in serious injury or death in the event of electrical contact.

DANGER: An insulated platform provides no protection from contact between two energized conductors or between an energized conductor and a grounded conductor by the operator, even with insulated machines.

WARNING: Due to the presence of metal parts the boom-tip of a digger derrick must be considered conductive. If any part of the boom-tip contacts an energized conductor, the entire boom-tip, including the control, must be considered grounded.

WARNING: Hydraulic fluid is flammable. Contact by any part of the boom-tip with an energized conductor while the boom-tip is also in contact with another energized source or a grounded object can cause the hydraulic fluid at the boom-tip to burn or explode and cause serious injury or death.

DANGER: Never pass platforms between energized power lines, even with insulated machines. (16)

DANGER: With an insulated machine, never approach energized power lines with any part of your machine unless all local, State/Provincial, company work rules and Federal (OSHA) required safety precautions have been taken. Use extreme caution. YOU MUST ALLOW FOR PLATFORM SWAY, ROCKING AND CREEP, AS WELL AS ELECTRICAL LINE SWAYING.

Check overhead clearances: Know your margin of safety. If possible, have power to the lines disconnected. If not possible, request a signal person for guidance to maintain at least minimum distance required by OSHA from energized power lines.

DANGER: Contact with energized power lines will cause DEATH or serious injury to persons in the platform and those on the ground in contact with the machine. Maintain adequate clearance.

WARNING: Do not operate your digger derrick during electrical storms. (17)

WARNING: Your platform and platform liner, synthetic winch cable and insulated boom section must be dry and clean before operating your digger derrick on or near energized power lines and apparatus. Moisture, grease and debris will defeat the insulating value of these components, which could result in serious injury or death.

WARNING: DO NOT drill drain holes in insulated platform or platform liners.

DANGER: NO DIGGER DERRICK, WHETHER INSULATED OR NOT, PROVIDES ANY ELECTRICAL PROTECTION TO ANY OCCUPANT OF THE PLATFORM IF THERE IS PHASE-TO-PHASE OR PHASE-TO-GROUND CONTACT. SUCH CONTACT WILL CAUSE SEVERE INJURY OR DEATH.

DANGER: Contact can be made when any portion of the boom tip is in contact with a phase or ground and the operator is in contact with another phase or ground and contact is made with any area of the boom tip by the operator.

WARNING: In case of an accident, or other emergency, involving any energized electrical source. DO NOT approach or enter the vehicle unless you are certain the vehicle is NOT energized. If the vehicle is energized, or you are not sure. stand on an insulated pad or blanket, use a long insulated pole to operate the emergency/lower control system to bring the platform down. (18)

Operation

WARNING: Anyone operating the platform must wear an approved fall protection device and lanyard attached to the anchor point.

WARNING: Never allow anyone to tamper with, service. or operate an digger derrick from the lower control station while personnel are in the platform. except in an emergency or equipment malfunction. Move the controls smoothly. For final positioning of the platform. gently "feather" the controls

WARNING: Jerking the controls will cause sudden starts and stops in platform operation. This can cause damaging shock loads and/or cause the platform to sway violently. When the platform has been raised to the working position, be extremely cautious to prevent any objects from striking or interfering with the operating controls. Secure all tools, equipment or other materials placed on the platform to keep them from shifting or falling. (19)

WARNING: Never disconnect your fall protection device while aloft. Any sudden machine movement can cause you to fall from the platform. (20)

WARNING: Never belt off to an adjacent pole, tree or other structure when working from a digger derrick platform. (21)

WARNING: Never attempt to transfer from the platform to a pole. tower, tree or any adjacent structure while the booms are in a raised position.

WARNING: When raising, lowering or rotating the platform, use extreme caution. Always look in the direction of movement. Watch out for obstructions above, below and to all sides. If necessary, use a signal person on the ground to guide you.

Stowage And Preparation For Transport (22)

After completing work at a jobsite, follow instructions in your operating manual for proper stowage of equipment and attachments. While each unit and work site will be slightly different, the following should be included:

• Stow the auger if it is not already stowed.
• If the personnel platform is deployed, remove all tools, equipment and other loose objects. Stow and lock the platform in its travel position.
• Return the load line, hook and boom attachments to their stowed position.
• Return the boom to its travel position being careful to meter the controls during this process. Fasten all straps and locks. Place the boom rotation brake (if equipped) in the travel position.
• Clean and stow all tools and equipment so no loose objects remain in the truck bed.
• Retract the outriggers to the stowed position. Be careful that all crew members and bystanders are clear of the outriggers
• Disengage the PTO and return the engine to idle. Replace wheel chocks and barriers in their travel positions. Check the work area for tools and equipment.
• Make note of any operating occurrence that indicates a need for maintenance or repair.

Proper maintenance is necessary to provide safe, reliable operation of the digger derrick.

Be certain that the digger derrick you are operating has been properly maintained by qualified personnel. Read and understand the manufacturer's manual(s) pertaining to your equipment. Perform all operator's inspections required by the manuals and or federal, local, or state/provincial regulations.

Prepare The Work Area (24)

Choose a clean, level work area. Make sure you have sufficient room. Check clearances. Make certain there is adequate light and ventilation. Clean the walking and working surfaces. Remove oil, grease, and water to eliminate slippery areas. Put sand or other absorbent material on slippery areas.

Prepare Yourself (25)

Wear all the protective clothing the job requires. Wear a rubber apron and rubber gloves when working with corrosive materials. Wear gloves and safety shoes when handling wooden blocks, wire rope or sharp-edged metal or heavy objects. Safety shoes must be worn at all times.

Safety glasses, goggles or a face-shield are always needed for eye protection from electric arcs from shorts, fluids under pressure, while grinding, servicing batteries, and from flying debris or loose material when engine is running or tools are used. Wear a face-shield when you disassemble spring loaded components or work with battery acid. Wear a helmet or goggles with special lenses when you weld or cut with a torch.

Do not sand. grind. flame-cut, braze or weld without a NIOSH/MSHA approved respirator or appropriate ventilation. If welding is required on this machine, refer to the manufacturer's manuals or consult your equipment dealer for proper procedures including welder certification requirements, proper grounding procedures and disconnecting of alternator or battery.

Block the boom or purge the cylinders of all air when doing maintenance to prevent free fall.

Handle tools and heavy parts CAREFULLY—with regard for yourself and other persons. LOWER ITEMS—DON'T DROP THEM. (26)

WARNING: Keep clear of all rotating components. Wrapping or entanglement may result in serious injury or death. KEEP HANDS—AND CLOTHING—AWAY FROM ALL MOVING PARTS. Don't tempt fate with dangling ties. loose sleeves, rings or long hair. Keep pockets free of all objects which could fall out—and into machinery. (27)

Prepare The Machine

WARNING: START THE ENGINE FROM THE DESIGNATED CONTROL AREAS ONLY. If starting from a remote station be sure the transmission is in park or neutral, the parking brake is set and the wheels are chocked. NEVER ATTEMPT TO START THE ENGINE BY SHORTING ACROSS STARTER TERMINALS OR REACHING FROM THE GROUND OR OUTSIDE THE CAB. It may start in gear if neutral-start circuitry is bypassed. This could cause the unit to move suddenly and cause serious injury or death to anyone in its path. Move the machine onto a level surface. Stop engine, release all hydraulic pressure. Attach the cylinder rod support struts or block all hydraulically operated components if they must be in a raised position.

WARNING: DO NOT DISCONNECT HYDRAULIC COMPONENTS WHEN THERE IS PRESSURE IN THE SYSTEM. Disconnecting pressurized hose can result in serious injury to the exposed, unprotected face or other parts of your body. (28)

WARNING: Never work on machinery with the engine running unless so instructed for specific service, by the manufacturer's operator's or service manuals.

WARNING: Never operate any type of engine without proper ventilation—EXHAUST FUMES KILL. (29)

If it is necessary to run an engine in an enclosed area, remove the exhaust fumes from the area with an exhaust pipe extension. If you do not have an exhaust pipe extension, make sure you open the doors and get outside air into the area. If adjustments must be made with the engine running, always work as a two-person team with one person sitting in the driver's seat while the other works on the machine. Remove only guards or covers that provide access. Wipe away excess grease and oil. Never leave guards off or access doors open when unattended. Keep bystanders away if access doors are open. Make certain all guards, screens or panels, and safety signs are reinstalled on the machine as recommended by the manufacturer.

DANGER: Never substitute a conductive wire braid type hose for any insulated or nonconductive hose. Death or serious injury will result from the bridging of an insulated gap with a conductive hose. Most non-conductive hoses are orange in color and are marked as "nonconductive". Hoses must not have pinhole perforations. bubbles or cuts.

Insulated Test

Test the liner and insulated boom section(s) of your digger derrick regularly per ANSI's A92 (A92.2) latest revision. (30) (Periodic/Maintenance Test Procedures)

WARNING: When hose. oil or other components that pass through the insulated section of the boom(s are replaced, an electrical insulation test must be performed.

Use Jacks And Hoists Carefully

If you must work beneath a raised vehicle during disassembly or maintenance, always use a truck lift or use wood (NOT CONCRETE) blocks, jack-stands or other rigid and stable supports to brace all movable portions of the digger derrick. (31) If these steps are not taken, components may shift or move during disassembly which could cause pinching or crushing injuries. When using jacks and hoists always be sure they are adequately supported.

WARNING: Never use concrete blocks for supports. They can collapse even under light loads. Make sure the hoist or jacks you use are in good repair. Never use jacks with cracked, bent or twisted parts. Never use frayed. twisted or pinched cables. Never use bent or distorted hooks.

31 RIGHT

Avoid Electrical System Hazards

Disconnect the battery before working on the electrical system. Remove the ground cables first. When reconnecting the battery, reconnect the ground cable last. Never work on the electrical system unless you are thoroughly familiar with system details and the special handling required. (32)

Brake Safety Tips

Always follow manufacturer's manual(s) when adjusting brakes. Improperly adjusted brakes can cause an accident. Block wheels before purging air from the brake system. Air trapped in brake lines can cause erratic performance or loss of brakes.

Use only brake fluid recommended by manufacturer.

Be Careful With Fluids Under Pressure

The hydraulic system may be under pressure whenever the engine is running and may hold pressure even after shutdown. Install cylinder rod support struts or block the cylinders and equipment securely before working on the hydraulic system. Cycle all hydraulic steering and other controls after shutdown to relieve system pressure. When venting or filling the hydraulic system, loosen the filler cap slowly and remove it gradually. If the system is equipped with an accumulator, see the manufacturer's service manual for discharge and recharge instructions. Do not permit an open flame around the hydraulic system. Clean up spilled fluid immediately.

WARNING: Diesel fuel or hydraulic fluid under pressure can penetrate the skin or eyes and cause serious injury, blindness or death. Fluid leaks under pressure may not be visible. Use a piece of cardboard or wood to find leaks but do not use your bare hand. (33) Wear a face shield or safety goggles for eye protection. If any fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury.

Be Careful With Hot Cooling Systems (34)

WARNING: Liquid cooling systems build up pressure as the engine gets hot. Before removing the radiator cap, stop the engine and let the system cool. Remove the radiator cap only after the coolant is cold. For cooling systems with an overflow tank, the coolant can usually be checked at the tank without removal of the radiator cap. See manufacturer's instructions.

Avoid Fire And Explosion Hazards

Stop the engine and shut off electrical equipment while filling the fuel tank. Use extra caution when fueling a hot engine. Always ground the fuel nozzle against the filler neck to avoid sparks.

WARNING: NEVER SMOKE WHILE HANDLING FUEL OR WORKING ON THE FUEL SYSTEM. THE FUMES IN AN EMPTY FUEL CONTAINER ARE EXPLOSIVE, NEVER CUT OR WELD ON FUEL LINES, TANKS OR CONTAINERS. Handle all solvents and dry chemicals according to procedures identified on manufacturer's containers or MSDS bar material. Work in a well-ventilated area. Make sure you know where fire extinguishers are kept and how to use them. Remove all trash or debris from the vehicle. Make sure that oily rags or other flammable material are removed from the machine. Check for fuel, oil or hydraulic fluid leaks. Repair the leaks and clean the machine before you operate.

Ether is flammable. Do not smoke when using Ether. Always follow the instructions on the Ether can and in the manufacturer's manual(s) for your machine. Do not use Ether if the engine is equipped with a glow plug or other type of preheater. Always use a nonflammable solvent when you clean parts. Do not use gasoline, diesel fuel or other flammable fluids. (35) Store all flammable fluids and material away from your work area in suitable containers, as per local regulations. Do not store flammable fluid or gas containers in compartments with electrical controls. Check readiness of fire extinguishers.

Avoid Battery Hazards

WARNING: Lead-acid batteries contain sulfuric acid which can damage eyes or skin on contact. Always wear a face shield to avoid acid in eyes. If acid contacts eyes, flush immediately with clean water and get medical attention. Wear rubber gloves and protective clothing to keep acid off skin. If acid contacts skin, wash off immediately with clean water, then seek medical attention.

WARNING: Lead-acid batteries produce flammable and explosive gases. Keep arcs, sparks, flames and lighted tobacco away. Use flashlight to check battery electrolyte level. Always check with engine stopped.

Do not charge a battery or jump-start the engine if the battery is frozen. Warm to 60°F (15°C) or the battery may explode. (36)

Tire Maintenance

WARNING: Explosive separation of a tire and/or rim parts can cause serious injury or death. Always follow the manufacturer's recommendations or see your tire supplier. (37)

Special tools and procedures are required to change truck tires. To do it safely, it must be done correctly. Follow the step-by-step instructions given in a tire repair manual. Changing tires is a job better done by your tire service company. Always maintain the correct tire pressure. Do not inflate the tires above the recommended pressure. Inspect tires and wheels daily. Do not operate with low pressure, cuts, bubbles, damaged rims or missing lug bolts or nuts. Never cut or weld on the rim or rim parts. This could cause explosive decompression. Keep wheel lug nuts tightened to manufacturer's recommendations. A rise in tire pressure is normal during operation. It should NOT be reduced. When adjusting tire pressure, do so from a distance. Use a long hose with self-attaching chuck. Always stand behind tread when adjusting tire pressure.

Tire Repair

Tires are to be repaired only by a qualified individual using the proper procedures and safety equipment.

WARNING: Always use a safety cage or cable restraints when reinflating a repaired tire. (38)

Don't Exceed Safe Limits

Never set a relief valve, or other pressure limiting device, to a pressure higher than that recommended by the manufacturer. Don't close off overflow or bypass lines. (39)

Use parts, lubricants and service techniques recommended by the manufacturer.

Complete Servce And Repairs Before Machine Is Operated (40)

Tighten all bolts, fittings, and connections to torques specified by the manufacturer. Install all guards, covers, and shields after servicing. Replace or repair any damaged ones. Refill and recharge pressure systems only with manufacturer approved or recommended fluids.

Start the engine and check for leaks. Operate all controls to make sure machine is functioning properly. Cycle the boom, swing and outrigger controls several times to be sure cylinders are fully charged with oil. Road test machine if necessary. After testing, shut down, check the work you performed (any missing cotter pins, washers, locknuts, etc.). Recheck all fluid levels before releasing machine for operation.

Inspect all parts during repair and replace if cracked or damaged. Excessively worn or damaged parts can fail and cause injury or death. Replace any damaged or illegible decals.

WARNING: When hose, oil or other components that pass through the insulated section of the boom(s) are replaced, an electrical insulation test must be performed.
