Pilot Accumulator Functions
The pilot accumulator (1) is a pressure storage reservoir of the
control circuit which supplies pressure and enables to operate
the control circuit even after stopping the engine.
Thus, the front attachment can be lowered with its own weight
by using the control lever and pressure in the hydraulic circuit
can be released after stopping the engine.
Pressure Release Procedure of Hydraulic Circuit
1. Set the machine in the parking position.
2. Pull the pilot control shut-off lever to the LOCK position.
Perform items from 3 to 5 within 15 seconds.
As pressure in the accumulator gradually decreases after
stopping the engine, pressure in the hydraulic circuit can be
released only immediately after stopping the engine.
3. Stop the engine. Turn the key switch ON.
4. Push the pilot control shut-off lever to the UNLOCK
position.
5. Move the control levers and attachment pedals forward
and rearward or left and right to release pressure from
the hydraulic circuit.
6. Pull the pilot control shut-off lever to the LOCK position
and turn the key switch OFF.
