Foot brake adjustment
Parking brake adjustment
Adjustment of the lifting draw-bars of the hitch for a single-axle semi-trailer
Adjusting the bowden cable
Before the adjustment of the foot brake the parking brake
lever must be in the unbraked position and between the
nut (1) and pin (2) in the disc brake lever (3) there must be
some play. If you find zero play, loosen the nut (1) slightly.
Lift both the rear wheels and instruct your assistant to turn
one of them by hand. At the same time tighten the
adjustment nut (4) until the wheel cannot be turned. Stop
tightening. Then, loosed the adjustment nut by 5/6 of
a turn (5 tabs of the nut) and check the turning of the
wheel.
After this basic adjustment check the operation of the foot
brakes to see whether the braking effect of both the
wheels is the same. If not, loosen the adjustment nut (4)
by the required value on the side where the braking effect
is hi
her.

lever (3).
After this basic adjustment check the operation of the
parking brake to see whether the braking effect of both the
wheels is the same. If not, loosen the adjustment nut (1)

with the position control selected and the vibration

- 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.
