SAFETY
PRECAUTIONS FOR MAINTENANCE
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.
HANDLING SUSPENSION CYLINDER, ACCUMULATOR
The suspension cylinders and accumulator are charged with high-pressure nitrogen gas. If any mistake is made in
handling, it may cause serious personal injury. To prevent this, always follow the procedure below.
Do not remove or disassemble the cylinder.
Do not bring it near flame or dispose of it in fire.
Do not make holes in it, weld it, or use a cutting torch.
Do not bear any shock by hammering, rolling, etc..
Ask for your Komatsu distributor when sealing gas into the cylinder or releasing gas from it.
PERSONNEL
Only authorized personnel can service and repair the machine. Do not allow unauthorized personnel into the area.
If necessary, employ an observer.
WORK UNDER THE MACHINE
If it is necessary to go under the machine when it is raised in
order to carry out service or maintenance, support the machine
securely with blocks and stands strong enough to support the
weight of the machine.
When carrying out inspection of the machine with the dump
body raised, always set the dump lever to the HOLD position,
lock with the safety lock knob, then use the safety pin.
For details of using the safety pin, see "SAFETY PIN (PAGE
3-46)".
NOISE
When carrying out maintenance of the engine and you are exposed to noise for long periods of time, wear ear covers
or ear plugs while working.
If the noise from the machine is too loud, it may cause temporary or permanent hearing problems.
