PRECAUTIONS FOR MAINTENANCE SAFETY
2–46
WORK ON MACHINE
WORK ON MACHINE:PC-0000-2AWK00A
q
When carrying out maintenance work on the machine,
maintain the foothold clean and orderly to prevent falling.
Always observe the followings.
q
Avoid spilling of oil and grease.
q
Do not litter the tools.
q
Watch your step when walking around on the machine.
q
Remove mud and greases stuck to the shoe sole.
q
Do not try to jump down from the machine. When getting on
or off the machine, use the ladder and handrail, and support
your body at three points using hands and feet (both feet
and a hand or both hand and a foot).
q
You must walk along the access aisle for checking being
paved with non-slip pads. Do not try to climb on the engine
hood and cover to prevent personal injuries from falling or
failing over due to losing your footing.
WORK UNDER MACHINE OR WORK EQUIPMENT
WORK UNDER MACHINE OR WORK EQUIPMENT:ALL-0000-2AFK00A
Serious personal injuries can result from a falling machine or work equipment. Always observe the following.
q
Make sure the hoists or jacks you use are in good condition
and strong enough to handle the weight of the component.
Never use jacks at places where the machine is damaged,
bent, or twisted. Never use frayed, twisted or pinched wire
rope. Never use bent or distorted hooks.
q
It is extremely dangerous to work under the machine if the
track shoes are lifted off the ground and the machine is sup-
ported only with the work equipment. If any of the control
levers is touched by accident, or there is damage occurring
to the hydraulic piping, the work equipment or the machine
will suddenly drop. This is extremely dangerous. Never
work under the work equipment or the machine.
q
If it is necessary to raise the work equipment or the machine and then go under it to carry out inspection or
maintenance, support the work equipment and machine securely with blocks and stands strong enough to
support the weight of the work equipment and machine.
If the work equipment and machine are not supported, there is a hazard that they may come down and that this
may lead to serious personal injury or death.
q
Never use concrete blocks for supports. They can collapse under even light loads.
