WARNING: Failure to follow these safety precautions may lead
to a serious accident. 8. PRECAUTIONS FOR MAINTENANCE
MAINTENANCE WITH CHASSIS RAISED
‡ When carrying out operations with the work equipment or chassis raised, lock the front and rear
frames with the safety bar, return the control levers to HOLD, set the control lever safety lock to
the LOCK position, and block the work equipment and chassis.
‡ Block the wheels on the opposite side before jacking up. Set blocks under the machine after
checking up.
WORK ON TOP OF MACHINE
‡ When carrying out maintenance on top of the machine, make sure that the footholds are clean
and free of obstructions, and follow the precautions below to prevent yourself from falling.
• Do not spill oil or grease.
• Do not leave tools lying around.
• Mind your step when you are walking.
‡ Never jump down from the machine. When getting on or off the machine, always use the steps
and handrails, and maintain three-point contact (both feet and one hand or both hands and one
foot) at all times.
‡ Use protective equipment if necessary.

‡ When wiping the front glass of the cab, stand on the step on
the front frame. Move to the stop on the front frame from the
side step by fully articulating the machine.
MAINTENANCE WITH ENGINE RUNNING
To prevent injury, do not carry out maintenance with the engine running. If maintenance must be
carried out with the engine running, carry out the operation with at least two workers and do as
follows.
‡ One worker must always sit in the operator’s seat and be ready to stop the engine at any time.
All workers must maintain contact with the other workers.
‡ When carrying out operations near rotating parts, there is danger of being caught in the parts, so
be extremely careful.
‡ When cleaning inside the radiator, set safety lock 1 to the LOCK position to prevent the work
equipment from moving.
In addition, turn parking brake switch 2 to ON.
‡ Do not touch any control levers. If any control lever must be operated, always give a signal to the
other workers to warn them to move to a safe place.
‡ Never touch the fan blade or fan belt with any tool or any part of your body. There is danger of
serious injury.
