Air Bleeding Procedure

2. Winch brake [NOTICE]

Bleed the main and auxiliary winch circuits by following the procedures below. The procedures are common to the both circuits.

1. Engine speed: Idling (700 min-1)

2. Lever operation: Operate the lever by inching operation within the range that the drum can fun. Operate the lever so that the working pressure does not exceed the value described below.

2.5 MPa (25.5 kgf/cm2) (360 psi) (during hoisting up)

4.5 MPa (45.9 kgf/cm2) (650 psi) (during hoisting down)

3. Bleeding will be completed when the oil flowing out of the air-bleed plug hole contains no bubbles.

3. Service brake [NOTICE]

The vehicle has two boosters; one for the front wheel brakes and the other for the rear wheel brakes

Take care of spattering the brake fluid and the fluid level in the fluid reservoir while bleeding.

1. With the sufficient compressed air in the air reservoir, depress the brake pedal and loosen the air-bleed plug on the booster to bleed the circuit

2. Then tighten the air-bleed plug before releasing the brake pedal.

3. Repeat the above steps until the flowing brake fluid contains no air bubbles. After the air bubbles go out, tighten the air-bleed plug while letting the fluid flow out.

[NOTICE]

The vehicle has each two air-bleed plugs for the front axle and two for the rear axle.

4. Bleed the wheel cylinders in the calipers of the axles in the steps same as above.
