CHECKING CHARGE PRESSURE OF NITROGEN GAS IN ACCUMULATOR (FOR CON-
TROL CIRCUIT)

4

WARNING

The accumulator is charged with high-pressure nitrogen gas, so mistaken operation may cause an explo-
sion, which will lead to serious injury or damage. When handling the accumulator, always do as follows.
The pressure in the hydraulic circuit cannot be completely removed. When removing the hydraulic equip-
ment, do not stand in the direction that the oil spurts out when carrying out the operation. In addition,
loosen the bolts slowly when carrying out the operation.
Do not disassemble the accumulator.
Do not bring it near flame or dispose of it in fire.
Do not make holes in it or weld it.
Do not hit it, roll it, or subject it to any impact.
When disposing of the accumulator, the gas must be released. Please contact your Komatsu distributor to
have this work carried out.

NOTICE
If the nitrogen gas charge pressure in the accumulator is low and operations are continued, it will become
impossible to release the remaining pressure inside the hydraulic circuit if a failure occurs on the
machine.

FUNCTION OF ACCUMULATOR

4

The accumulator stores the pressure in the control circuit.
Even after the engine is stopped, the control circuit can be
operated, so the following actions are possible.

q

If the control lever is operated in the direction to lower the
work equipment, it is possible for the work equipment to go
down under its own weight.

q

The pressure in the hydraulic circuit can be released.

The accumulator is installed to the position shown in the dia-
gram on the right.
