SAFETY
ACCUMULATOR, GAS SPRING
The accumulator and gas springs is charged with high-
pressure nitrogen gas. When handling the accumulator,
careless procedure may cause an explosion which could lead
to serious injury or property damage. For this reason, always
observe the following precautions.
q Do not disassemble the accumulator.
q Do not bring it near flame or dispose of it in fire.
q Do not make holes in it, weld it, or use a cutting torch.
q Do not hit or roll the accumulator, or subject it to any
impact.
q When disposing of the accumulator, the gas must be
released. Please contact your Komatsu distributor to have
this work performed.
PERSONNEL
Do not allow any unauthorized personnel into the area when servicing the machine. If necessary, employ a guard.
ATTACHMENTS
q Appoint a leader before starting removal or installation
operations for attachments.
q Place attachments that have been removed from the
machine in a stable condition so that they do not fall. And
take steps to prevent unauthorized persons from entering
the storage area.
WORK UNDER THE MACHINE
q If it is necessary to go under the work equipment or the
machine to carry out service and maintenance, support the
work equipment and machine securely with blocks and
stands strong enough to support the weight of the work
equipment and machine.
q It is extremely dangerous to work under the machine if the
track shoes are lifted off the ground and the machine is
supported only with the work equipment. If any of the
control levers is touched by accident, or there is damage
occurring to the hydraulic piping, the work equipment or the
machine will suddenly drop. This is extremely dangerous.
Never work under the work equipment or the machine.
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.
