HANDLING ACCUMULATOR
WARNING
On machines equipped with an accumulator, for a short time after the engine is stopped, if the blade con-
trol lever is moved to the LOWER position, the work equipment will move down under its own weight.
After stopping the engine, always place the safety lever in the LOCK position.
The accumulator is filled with high-pressure nitrogen gas, and it is extremely dangerous if it is handled in
the wrong way. Always observe the following precautions.
● Never make any hole in the accumulator or expose it to flame or fire.
● Do not weld any boss to the accumulator.
● When disposing the accumulator, it is necessary to release the gas from the accumulator, so please
contact your Komatsu distributor.
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 to the position shown in the dia-
gram on the right.
