PROCEDURE FOR RELEASING INTERNAL PRESSURE IN HYDRAULIC CIRCUIT
WARNING
q
The hydraulic system is always under internal pressure, so when inspecting or replacing the piping or
hoses, always release the pressure in the circuit before starting. If the pressure is not released, high
pressure oil may spurt out and cause serious personal injury.

The parts and oil are at high temperature after the engine is stopped, and may cause serious burns.
Wait for the temperature to go down before starting the operation.

When the oil filler cap is removed, oil may spurt out, so turn the cap slowly to release the pressure
before removing the cap.

Stop the machine on firm level ground.
2.
Lower the blade to the ground, then stop the engine.
3.
To release the internal pressure, operate the blade control
lever in each direction to the end of its stroke within 15 sec-
onds after stopping the engine.

Loosen oil filler cap (F) at the top of the hydraulic tank
slowly to release the internal pressure.
5.

then stop the engine and operate the work equipment con-
trol lever to the front, rear, left, and right.
q
Repeat Step 3, 2 - 3 times to completely remove the
remaining pressure.
