PRECAUTIONS FOR MAINTENANCE

TWO WORKERS FOR MAINTENANCE WHEN ENGINE IS 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.
Lock the dump lever in HOLD position to prevent the operation
cab from moving. Also, set parking brake valve lever to the
PARKING position to prevent the machine from moving.
When carrying out operations near the fan, fan belt, or other rotating parts, there is a hazard of being caught in
the parts, so be careful not to come close.
Do not touch any control levers. If any control lever must be operated, give a signal to the other workers to warn
them to move to a safe place.
Never drop or insert tools or other objects into the fan or fan belt. Parts may break or be sent flying.

PROPER TOOLS

Use only tools suited to the task and be sure to use the tools
correctly. Using damaged, low quality, faulty, makeshift tools or
improper use of the tools could cause serious personal injury.
