METHOD FOR RELEASING PRESSURE IN CONTROL CIRCUIT OF
MACHINES EQUIPPED WITH ACCUMULATOR
1. Lower the work equipment to the ground. Close any attach-
ment such as the crusher.
2. Stop the engine.
3. Set the safety lock lever completely in the FREE position,
operate the right control lever and attachment control pedal
fully to the front, rear, left, and right, to release the pressure in
the control circuit.
4. Set the safety lock lever completely in the LOCK position,
then lock the control levers and attachment control pedal.
Note that this does not completely release the pressure, so
when removing the accumulator in the control circuit, loosen
the connections slowly and do not stand in the direction
where the oil spurs out.
LONG-TERM STORAGE
If the machine is not to be used for a long time, do as follows.
● Set the stop valve in the LOCK condition.
● Install a blind plug to the valve.
● Set the selector valve to the position for general attachments
such as the crusher.
If there is no breaker or general attachment installed, operating
the pedal may cause overheating.
SPECIFICATIONS

● Oil flow - Refer to clamshell and breaker manufacturers rec-
ommendations for oil flow for specific attachment.
