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.
4. Bleed the wheel cylinders in the calipers of the
axles in the steps same as above.
[NOTICE]
The vehicle has four air-bleed plugs for the 1st axle
and two for the 2nd and 3rd axles.
4. Hydraulic motor assy
4.1 Slewing motor
[NOTICE]
Do not apply any load to the motor before
completing air bleeding.
Bleed the slewing motor by following either (1), (2) or
(3).
(1) Pour the hydraulic oil from the drain port until the
oil flows out.
(2) Perform the right or left slewing operation slowly
for approximately one minute.
(3) With the slewing brake being actuated, perform
the right or the left slewing operation and keep
the slewing circuit hydraulic pressure at
approximately 4.9 MPa (50 kgf/cm
