Wheel brake adjustment
Prevent the wheel brake swivel cam from
operating by inserting a tool (fig. item A, 4 mm
diameter pin) through the positioning hole.
Tighten up the adjusting nuts (fig. item C) on the
wheel brakes with a screwdriver (fig. item B or D)
or a spanner, depending on the design, until the
wheel will not rotate in the direction of travel.
Centre the brake shoes by applying the parking
brake several times.
Design 1:
Turn back the adjusting bolt by approx. one
turn, until no braking effect can be felt when
the wheel is turned in a forward direction.
Design 2:
Turn back the adjusting nut by approx. 3-5 teeth,
until no braking effect can be felt when the
wheel is turned in a forward direction.
Check the position of the brake equalizer
compensators with the parking brake applied.
Positioned at right angles to the brake rods =
even play on both wheel brakes. Readjust
brakes if necessary. As a test, apply the parking
brake slightly and check that the braking effect
(in the direction of travel) on both wheels (right
and left) is the same. Remove the locking device
(4 mm diameter pin) from the swivel cams.
Adjusting the transmission device
Always adjust the brake before readjusting the
transmission device.
With the transmission linkage supported, adjust
it so that there is no play or tension on the
turnbuckle (1) or the equalising compensator
(2). All the equalising compensators must be at
right angles to the brake linkage. Tighten all the
locknuts on the brake transmission system.
