12. METHOD FOR RELEASING PRESSURE
IN HYDRAULIC CIRCUIT
The pressure in the hydraulic circuit cannot be completely removed. When removing the
hydraulic equipment, do not stand in the direction that the oil spurts out when caring out the
operation. In addition, loose the bolts slowly when carrying out the operation.
Refer to "Operation 3.3 Starting Engine" for starting the engine. Also refer to the description in
"Operation" for starting and stopping, and turning the travel direction, as applicable.
Carry out the following procedure to operate the blade control lever fully to the front and rear
within 15 seconds of stopping the engine. When the engine stops, the pressure in the
accumulator will gradually go down, so the pressure can only be release immediately after the
engine is stopped.
1. Stop the machine at leveled location.
2. Lower the blade to the ground.
3. Turn the starter switch to the OFF position and stop the engine.
4. Turn the starter switch to the ON position.
5. Set the lock lever to the FREE position (F), then operate each
work equipment control lever and blade control lever fully to the
front, rear ,left and right to release the pressure in the hydraulic
circuit.
6. Set the lock lever to the LOCK position (L) to lock the work
equipment control levers and blade control lever.
