- Take the similar procedure for the front brake circuit and rear brake circuit. (2 places each).
- Perform air bleeding in order of right side of rear axle -> left side of rear axle -> right side of front axle -> left side of front axle -> slack adjuster.
Bleeding air
1. Start the engine to accumulate pressure in the accumulator, and then stop the engine.
2. Remove inspection cover (1) of the front frame.
- When removing the inspection cover with the boom raised, place a stand under the boom to support the boom securely.
3. Connect hose [1] to bleeder screw (2) of slack adjuster, and place one end of hose [1] in the oil
container.
4. Depress the brake pedal, and then loosen bleeder screw (2) to bleed air.
- Release the brake pedal slowly after tightening bleeder screw (2).
5. Connect hose [1] to bleeder screw (3) of wheel brake, and place one end of hose [1] in the oil
container.
6. Depress the brake pedal and then loosen bleeder screw (3) to bleed air.
- Release the brake pedal slowly after tightening bleeder screw (3).
7. Repeat this operation until the oil flowing through hose [1] becomes free from bubbles.
Then depress the pedal fully, and tighten bleeder screw (2) and (3) while the oil is flowing.
