11.19 HANDLING THE ACCUMULATOR
WARNING
On machines equipped with an accumulator, for a short time af-
ter the engine is stopped, if the work equipment 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 safety lock 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 of the accumulator, it is necessary to re
lease the gas from the accumulator, so please contact your
Komatsu distributor.
This machine is equipped with the accumulator in the control circuit.
The accumulator is a device to store the pressure in the control circuit,
and when it is installed, the control circuit can be operated 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 diagram on
the right.
