ACCUMULATOR, HANDLING

WARNING
On machines equipped with an accumulator, for a short time after the engine is stopped, if the work equip-
ment control lever is moved to the LOWER position, the work equipment will move down under its own
weight.
After stopping the engine, always place the work equipment lock lever and parking lever in the LOCK posi-
tion.
The accumulator is charged with high-pressure nitrogen gas, so improper operation may cause an explo-
sion which will lead to serious injury or damage. When handling the accumulator, always do as follows:
Pressure in the control circuit cannot be completely removed. When removing the hydraulic equipment,
do not stand in the direction that oil spurts out when performing the operation.
Loosen the bolts slowly.
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. Contact your Komatsu distributor for
proper disposal.
The accumulator is a device to store the pressure in the control
circuit, and when it is installed, the control circuit can be oper-
ated for a short time even after the engine is stopped.
Therefore, if the control lever is moved in the direction to lower
the work equipment, it is possible for the work equipment to
move under its own weight.
The accumulator is installed in the position shown in the dia-
gram on the right.
METHOD OF RELEASING PRESSURE IN OPERATING CIRCUIT ON MACHINE EQUIPPED
WITH ACCUMULATOR
3
1.
Lower the work equipment and stop the engine.
2.
After stopping the engine, operate control lever full strokes
to the front, rear, left, and right to release pressure inside
the work equipment circuit.
However, the pressure cannot be completely released, so
if accumulator in the work equipment circuit is removed,
loosen the screws slowly, and never stand in the direction
oil spurts out.
