WARNING
The accumulator is charged with high-pressure nitrogen gas, so wrong handling may cause an explosion,
which will lead to serious personal injury or damage. When handling the accumulator, always observe the
followings.
q
The pressure in the hydraulic circuit cannot be completely removed. When removing the hydraulic
equipment, do not stand in the direction in which the oil spurts out when carrying out the work. In
addition, loosen the bolts slowly when carrying out the work.
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 or weld it.
q
Do not hit it, roll it, or subject it to any impact.
q
When disposing of the accumulator, the gas must be released. Ask your Komatsu distributor for the
work.
If operations are continued after the performance of the accu-
mulator drops, it will be impossible to release the remaining
pressure in the hydraulic circuit if there should be a failure on
the machine.
Ask your Komatsu distributor to replace the accumulator.
The accumulator is installed to the position shown in the figure
