Adjustment and Readjustment of the Overrun
Braking System
ADJUSTING THE BRAKING SYSTEM
Preparations:
1.
Place the trailer on jacks with the wheels off of the
ground.
2.
Release the handbrake
3.
Pull out the drawbar as far as it will go.
Preliminary Requirements:
1.
When carrying out adjustments, always start with the
wheel brakes.
2.
When carrying out adjustments, turn the wheel only in
the direction of forward travel.
3.
Do not pre-tension the expanding locking mechanism
in the brake. If necessary, loosen the brake linkage at the
brake compensator.
4.
Check the expanding locking mechanism and control
cable for ease of movement.
NEVER READJUST THE BRAKING SYSTEM OR BRAKES BY THE BRAKE LINKAGE
OR TURNBUCKLES (IF APPLICABLE) IN THE LINKAGE. THE COMPRESSION
SPRING MAY ONLY BE LIGHTLY PRE-TENSIONED AND MUST NOT BECOME
FULLY COMPRESSED WHEN ACTIVATED!
ADJUSTMENT PROCEDURE
1.
Brake
a.
Loosen the linkage
b.
Tighten the adjusting screw (12) (on the outside of
the brake plate, opposite the cable entry[13]), turn-
ing clockwise until the wheel can only be turned
with difficulty or not at all.
c.
Ease off the adjusting screw (12) in the counter-
clockwise direction (approx. 1/2 turn) until the
wheel turns freely. Slight rubbing noises, which do
not effect the free turning of the wheel, are permit-
ted.
d.
When the brake is correctly adjusted, the actuating
travel of the control cable (11) will be 5-8 mm.
e.
Repeat the procedure on the other wheel.
