Performance of Maintenance
Unless otherwise specified, maintenance should be
performed with the machine parked on level ground,
the blade resting on the ground, the transmission
control lever in NEUTRAL, the parking brake engaged,
the engine stopped, and the electrical disconnect
switch in the OFF position.
Pressure air can cause personal injury. When using
pressure air for cleaning, wear a protective face shield,
protective clothing, and protective shoes.
The maximum air pressure must be below 205 kPa
(30 psi) for cleaning purposes.
Always use a board or cardboard when checking for a
leak. Escaping fluid under pressure, even a pin-hole
size leak, can penetrate body tissue, causing serious
injury, and possible death. If fluid is injected into your
skin, it must be treated immediately by a doctor
familiar with this type of injury.
Crushing or Cutting Prevention
Support equipment and attachments properly when
working beneath them. Do not depend on hydraulic
cylinders to hold them up. Any attachment can fall if a
control is moved, or if a hydraulic line breaks.
Never attempt adjustments while the machine is
moving, or the engine is running, unless otherwise
Where there are attachment linkages, the clearance in
the linkage area will increase or decrease with
movement of the attachment.
Stay clear of all rotating and moving parts.
Keep objects away from moving fan blades. They will
throw or cut any object or tool that falls, or is pushed,
Do not use a kinked or frayed wire rope cable. Wear
gloves when handling the wire rope cable.
Retainer pins, when struck with force, can fly out and
injure nearby persons. Make sure the area is clear of
people when driving retainer pins.
Wear protective glasses when striking a retainer pin,
to avoid injury to your eyes.
Chips, or other debris, can fly off objects when struck.
Make sure no one can be injured by flying debris
before striking any object.
Rollover Protective Structure (ROPS) or
Falling Objects Protective Structure (FOPS)
ROPS or FOPS are guards located above the
operator's compartment and secured to the machine.
To avoid any possible weakening of the ROPS or
FOPS, consult TACOM or any Caterpillar dealer before
altering, adding weight to, welding on, or cutting or
drilling holes into the structure.
Any alteration not specifically authorized by Caterpillar
invalidates Caterpillar's ROPS and FOPS certification.
The protection offered by the ROPS/FOPS will be
impaired if it has been subjected to structural damage.
Structural damage can be caused by an overturn
accident, by falling objects, etc.
At operating temperature, the engine coolant is hot
and under pressure. The radiator and all lines to
heaters, or the engine, contain hot coolant or steam.
Any contact can cause severe burns.
Steam can cause personal injury.
Check the coolant level only after the engine has been
stopped and the fill cap is cool enough to remove with
your bare hand.
Remove the cooling system fill cap slowly to relieve
Cooling system additive contains alkali that can cause
personal injury. Avoid contact with the skin, eyes, and
Allow cooling system components to cool before
Hot oil and components can cause personal injury. Do
not allow hot oil or components to contact the skin.
At operating temperature, the hydraulic tank is hot and
can be under pressure.
