Brake adjustment
FHD18N079
Brake adjustment nuts are accessible from the rear of the tractor near the brake cylinders (A).
Before adjusting the brakes, the handbrake lever must be in the released position.
First, secure the tractor against movement, lift the left rear wheel with the jack to avoid touching the ground
and support the rear axle.
Let the assistant spin the left rear wheel by the hand. At the same time, tighten the adjustment nut (1) on the
left brake cylinder until the left rear wheel stops spinning. Do not tighten more. Then adjust the adjustment
nut (1) by 5/6 turns (5 sides of the nut) and check that it can be turned around. In the same way, adjust the
right rear wheel brake with the nut (1) on the right brake cylinder.
After this basic adjustment, check the operation of the foot brakes for both wheels to have the same braking
effect.
If this is not the case, then on the side having a greater braking effect, loosen the adjusting nut (1) by the
required value.
Adjustment of the lifting draw-bars of the hitch for a single-axle semi-trailer
- Raise the hydraulic arms to the upper - transport position
with the position control selected and the vibration
compensator off.
- Screw the nuts on the adjustable draw-bars towards the
guiding pipe without any play.
- Tighten the nuts by another 3.5 turns.
- Check whether it is possible to tilt off the supporting
hooks freely.
- By lowering and repeated lifting of the hydraulic arms to
the transport position check whether the engine does not
tend to 'stall' at the idle speed - the relief valve of the
hydraulic pump must not be in operation.
- Then, lower the arms slightly.
