Service Brake - Air Bleeding - Case WX145 Operator's Manual

SECTION 4

SERVICE BRAKE - AIR BLEEDING

The braking system of this machine consists of two
braking circuits. One circuit is designed for the pair
of wheels of the steering axle, while the other circuit
is designed for the pair of wheels of the rigid axle.
If works have been performed on the braking sys-
tem, causing the penetration of air inside of the sys-
tem, for instance during a hose replacement, once
these works have been completed, bleed the air
from the concerned circuit.
Secure the machine so that it cannot move acciden-
tally.
Link a hose on the connection (1) of a multi-plate
brake.
Connect the other end of the hose with a container,
previously filled with hydraulic oil.
Start the engine.
Depress the pedal and hold, until hydraulic oil, flows
out from the hose without air bubbles.
Repeat this operation also with the other brake of
the same axle. In this way air is bleeded from one
braking circuit.
STEERING ADJUSTMENT
To ensure the correct travel and steering operation,
the steering stop has to be adjusted according to
machine type. According to the axle and tyres type,
also the steering stop changes.
At each axle or tyres change, adjust correctly the
steering stop and keep it constantly under control.
Through the axle joint rotation (4), the steering force
are transferred to the wheel, which on its turn, is
steered by the stub axle. The steering stop is limited
by a spacer (1), fastened to the joint by means of a
screw (2) and a thrust stop (3), placed on the axle
body. In this way the steering wheels can turn safely
without coming in touch with other elements, even
when they are completely steered and the axle is
fully inclined.
