introduction of this manual and the cautions presented
throughout the text of the manual.
This is the safety-alert symbol. When you see this
symbol on the machine or in this manual, be alert to the
potential for personal injury.
Technical manuals are divided in two parts: repair and
operation and tests. Repair sections tell how to repair the
components. Operation and tests sections help you
identify the majority of routine failures quickly.
Information is organized in groups for the various
components requiring service instruction. At the beginning
of each group are summary listings of all applicable
essential tools, service equipment and tools, other
materials needed to do the job, service parts kits,
specifications, wear tolerances, and torque values.
Technical Manuals are concise guides for specific
machines. They are on-the-job guides containing only the
vital information needed for diagnosis, analysis, testing,
and repair.
Fundamental service information is available from other
sources covering basic theory of operation, fundamentals
of troubleshooting, general maintenance, and basic type
of failures and their causes.

obstacles or overhead electrical lines. Never move
machine closer than 3 m (10 ft) plus twice the line
insulator length to overhead wires.
Keep bystanders clear at all times. Keep bystanders
away from raised booms, attachments, and unsupported
loads. Avoid swinging or raising booms, attachments, or
loads over or near personnel. Use barricades or a signal
person to keep vehicles and pedestrians away. Use a
signal person if moving machine in congested areas or
where visibility is restricted. Always keep signal person in
view. Coordinate hand signals before starting machine.
Operate only on solid footing with strength sufficient to
support machine. Be especially alert working near
embankments or excavations.
Avoid working under over-hanging embankments or
stockpiles that could collapse under or on machine.
Reduce machine speed when operating with tool on or
near ground when obstacles may be hidden (e.g., during
snow removal or clearing mud, dirt, etc.). At high speeds
hitting obstacles (rocks, uneven concrete or manholes)
can cause a sudden stop. Always wear your seat belt.

• Do not support machine with cinder blocks or wooden
pieces that may crumble or crush.
• Do not support machine with a single jack or other
devices that may slip out of place.
Understand service procedures before beginning repairs.
Keep service area clean and dry. Use two people
whenever the engine must be running for service work.
OUT4001,000026D –19–20NOV08–1/1
Service Cooling System Safely
Explosive release of fluids from pressurized cooling
system can cause serious burns.
Shut off engine. Only remove filler cap when cool enough
to touch with bare hands. Slowly loosen cap to first stop
to relieve pressure before removing completely.

Remove Paint Before Welding or Heating
Hazardous fumes can be generated when paint is heated
by welding or using a torch. Dust from sanding or grinding
paint can also be hazardous.
Remove paint to at least 76 mm (3 in.) from area to be
heated. Wear an approved respirator when sanding or
grinding paint. If a solvent or paint stripper is used, wash
area with soap and water. Remove solvent or paint
stripper containers from work area, and allow fumes to
disperse at least 15 minutes before welding or heating.
Work outside or in a well-ventilated area. Dispose of
waste, paint, and solvents properly.
TX03679,0001732 –19–29AUG07–1/1
Make Welding Repairs Safely
IMPORTANT: Disable electrical power before welding.
Turn off main battery switch or
disconnect positive battery cable.
Separate harness connectors to engine
and vehicle microprocessors.
Avoid welding or heating near pressurized fluid lines.
Flammable spray may result and cause severe burns if
pressurized lines fail as a result of heating. Do not let heat
go beyond work area to nearby pressurized lines.
Remove paint properly. Do not inhale paint dust or fumes.
Use a qualified welding technician for structural repairs.
Make sure there is good ventilation. Wear eye protection
and protective equipment when welding.

Drive Metal Pins Safely
9000
01
15
Always wear protective goggles or safety glasses and
other protective equipment before striking hardened parts.
Hammering hardened metal parts such as pins and
bucket teeth may dislodge chips at high velocity.
Use a soft hammer or a brass bar between hammer and
object to prevent chipping.
TX03679,0001745 –19–03JAN07–1/1
Service Tires Safely
Explosive separation of a tire and rim parts can cause
serious injury or death.
Do not attempt to mount a tire unless you have the proper
equipment and experience to perform the job.
Always maintain the correct tire pressure. Do not inflate
the tires above the recommended pressure. Never weld or
heat a wheel and tire assembly. The heat can cause an
increase in air pressure resulting in a tire explosion.
Welding can structurally weaken or deform the wheel.
When inflating tires, use a clip-on chuck and extension
hose long enough to allow you to stand to one side and
NOT in front of or over the tire assembly. Use a safety
cage if available.
Check wheels for low pressure, cuts, bubbles, damaged
rims or missing lug bolts and nuts.
