Maintenance precautions [60621721]
• Do not attempt repairs unless trained. Refer to manuals
and experienced repair personnel for help.
• Before you service the machine, always place a DO
NOT OPERATE tag on the key switch. Make sure that
the machine is clearly “tagged out”.
• Wear protective glasses and other required safety
equipment when servicing or repairing the machine.
• Wear gloves to protect hands when handling cable.
• Disconnect the battery before working on the electrical
system. Know the consequences of disconnecting any
electronic or computer devices.
• Avoid lubrication or mechanical adjustments with the
machine in motion or the engine operating. If the en-
gine must be in operation to make certain adjustments,
place the transmission in neutral, apply the parking de-
vice, place the bucket/attachment in a safe position, se-
curely block the wheels and use extreme caution.
• Securely block the machine or any component that may
fall before working on the machine or component. If
possible, use a back up or secondary blocking device
as well.
• Unexpected vehicle movement can result in death or
serious injury. Apply parking brake, turn off engine and
secure machine with wheel chocks.
• To prevent unexpected movement, securely block
working elements when repairing or changing working
tool parts such as cutting edges.
• Never make repairs on pressurized components, fluid,
gas or mechanical until the pressure has been relieved
according to the manufacturer’s instructions.
• Use extreme caution when removing radiator, reservoir,
or tank caps, drain plugs, grease fittings or pressure
taps. Park the machine and let it cool before opening a
pressurized tank.
• Release all pressure before working on systems which
have an accumulator.
• Hydraulic oil or diesel fuel leaking under pressure can
penetrate the skin and cause infection or other injuries.
To prevent personal injury, relieve all pressure before
disconnecting fluid lines or performing work on the hy-
draulic system. Before applying pressure, make certain
all connections are tight and components are in good
condition.
• Use a piece of cardboard, newspaper, or wood to check
for any pressurized leaks to prevent fluid penetrating
the skin. Pressurize accumulators with the proper gas
according to manufacturer’s recommendations.
• When inflating tires, use a self-attaching inflation chuck
with remote shutoff and stand clear of the tire. Position
yourself beside the tire and not beside the rim.
• Towing this machine is not recommended.
• When absolutely necessary to tow the machine, do not
exceed the recommended towing speed. Be sure the
towing machine has sufficient braking capacity to stop
the towed load. If the towed machine cannot be braked,
a tow bar must be used or two towing machines must
be used - one in front pulling and one in the rear to act
as a brake. Avoid towing over long distances.
• Always observe proper maintenance procedures.
• Always replace all missing, illegible or damaged safety
signs or decals as necessary. Keeps all safety signs
and decals clean and legible.
Observe proper maintenance procedures
• Whenever servicing or replacing hardened pins, etc.,
use a brass drift or other suitable material between the
hammer and pin. Alt: Use a brass hammer, drift or
suitable material on the pin, etc.
• Keep the brakes and steering systems in good operat-
ing condition.
