Two Workers For Maintenance When Engine Is Running; Proper Tools - Komatsu HD325-6 Operation & Maintenance Manual

SAFETY

TWO WORKERS FOR MAINTENANCE WHEN ENGINE IS RUNNING

To prevent personal 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.
Set the dump lever to the HOLD position, and lock with dump
lever lock (1) to prevent the dump body from moving. In
addition, set parking brake valve lever (2) 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 the gear shift lever or dump lever. If the gear shift lever or dump 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.
