Checking the function of the automatic linkage adjuster
1. Remove the rubber stopper cap.
2. Slacken the adjusting screw (arrow) with a
ring spanner
(Fig. 88) approx. ¾ of a turn anti-clockwise.
There must be free travel of at least 50 mm
for a lever length of 150 mm.
3. Actuate the brake lever several times by
hand. This should cause a smooth auto-
matic readjustment; it should be possible to
hear the coupling engaging and, on the
back stroke, the adjusting screw should turn
clockwise slightly.
4. Refit the stopper cap.
5. Lubricate with BPW ECO_Li91 special high
melting point grease.

Adjusting the S3008 RAZG expanding lever brake
1. Tension lever system for ramp equipment
and for releasing the hand brake lever.
2. Tighten the regulating screws on the wheel
brakes in the direction of the arrow, using a
screwdriver, until the wheel is hard to turn in
the direction of travel.
3. Turn the regulating screw back until a brak-
ing effect can no longer be felt when the
wheel turns forwards.
4. Reinstall the tension lever system for ramp
equipment and adjust it so that it is free
from play.
5. As a test, apply the parking brake slightly
and use the same braking torque (in the di-
rection of travel) to check the wheels on the
left and right.
