Maintenance
Bleeding air from the front brake
circuit
After having carefully carried out operations 1 to 7 to bleed
the rear brakes, proceed in the following way:
1 - Depress both brake pedals at the same time. Use
the special coupling lock to keep the pedals together.
Unscrew the bleed screw (4) on the on-off valve (3)
until bubble-free oil flows out.
Re-tighten the screw and release the pedals.
2 - Depress both pedals at the same time and slacken
off the two bleed screws (5) at the rear of the central
part of the front axle.
Repeat this operation until bubble-free oil flows out.
NOTE: if the tractor is equipped with a valve for hydraulic
trailer braking, it will also be necessary to bleed off
any air in the piloting tube of this valve. A screw on
the body of the valve allows this operation to be easily
carried out.(6)
3 - Check free pedal travel and that the front brakes act
at the same time. Do this by testing the action on
the road.
4 - After having done this, top up the level in the reservoir
with oil of the prescribed type.
WARNING: Always keep the brake pedals cou-
pled for on-road driving in order to ensure si-
multaneous braking on both sides. Never use
the brakes independently on public roads.
When working on slopes, avoid using the
brakes as much as possible. Instead, select a
lower gear and use engine braking.
GENERAL MAINTENANCE
WARNING: Always use specific personal safety devices
for each operation. Beware of burns caused by hot
tractor parts.
