PRECAUTIONS FOR MAINTENANCE
BEFORE PERFORMING MAINTENANCE
Warning Tag
•
Starting the engine or operating the controls while
others are performing maintenance on the truck
can lead to serious injury and/or death.
•
Always attach the warning tag to the steering
wheel in the operator's cab to alert others that
you are working on the machine. Attach
additional warning tags around the machine, if
necessary.
•
Tags are available from your Komatsu distributor.
•
Warning tag part number (09963-03001)
Proper Tools
•
Use only tools suited
to
the
task.
Using
damaged, low quality,
faulty,
or
makeshift
tools
can
cause
personal injury.
Stopping The Engine Before Service
•
Before performing inspections or maintenance,
stop the machine on firm, flat ground. Lower the
dump body, stop the engine and apply the
parking brake.
•
If the engine must be operated during service,
such as when cleaning the radiator, always move
the transmission control lever to the NEUTRAL
position and apply the parking brake. Always
perform this work with two people. One person
must sit in the operator's seat to stop the engine,
if necessary. Never move any controls, not
related to the task at hand, during these
situations.
•
When servicing the machine, DO NOT touch any
moving parts. Never wear loose clothing or
jewelry.
•
Put wheel blocks under the wheels to prevent
machine movement.
•
When performing service with the dump body
raised, always place the dump lever in the HOLD
position. Install the body-up retention cable,
securely.
Securing The Dump Body
Any time personnel are required to perform main-
tenance on the vehicle with the dump body in the
raised position, the body-up retention cable must
be installed.
The Komatsu body-up retention cable can only
be used with a Komatsu body. Non-OEM dump
bodies may not accommodate the Komatsu
body-up retention cable. The end user must
ensure that a proper cable/sling is used.
1. To hold the dump body in the raised position,
raise the body to it's maximum height. Refer to
Figure 20-1.
