Adjustment of the slack adjuster
– every 200 hours in operation –
Move the slack adjuster by hand in the
direction of brake application. If there is a
maximum free play on the long�stroke
diaphragm cylinder of 35 mm, the wheel
brake must be adjusted.
Adjust the free play "a" to 10�12 % of
the length (B) of the brake lever connected
to it.
E.g. for a lever length of 150 mm,
the free play is 15�18 mm.

Brake adjustment
Depending on the nature and extent of
operation, the brakes should be checked
regularly and adjusted, if necessary.
Adjustment is necessary when approx.
2/3 of the maximum cylinder stroke is
used under heavy braking. For this
purpose, jack up the axle and secure the
vehicle against accidental movement.

Adjustment of the brake lever
– every 200 hours in operation –
Undo the hexagonal nuts, remove the
bolts. Bend open the slot in the brake
levers a little. The brake levers can now be
withdrawn.
Turn the brake camshafts until the linings
start to rub against the brake drums. Push
the brake levers onto the brake camshafts
in the correct position until they are fully
home. Insert the bolts and fit the nuts.

Brake lining check
– every 200 hours in operation –
Open the inspection hole by removing
the rubber bung (if present).
If the remaining thickness of the brake
lining is
a: for riveted linings,
5 mm
(N 2504)
3 mm
b: for bonded linings
2 mm
the brake lining must be replaced.
Re�insert the rubber bung.

Adjustment of wedge-type brakes
– every 200 hours in operation –
S 3006�7 RAZG:
Secure the trailer to prevent it moving and
jack it up. Disconnect the pull rods from
the overrun hitch and the handbrake lever.
Lock the swivel cam on the wheel brake
with the help of special tool A (< 4 mm dia�
meter pin) by inserting it through the posi�
tioning hole (at least 50 mm into the hole).
Tighten the adjusting nuts (item C) on the
wheel brakes with a spanner, with the help
of the adjusting bolt (item B), until the
wheel will not turn in the direction of travel.
Turn back the adjusting bolt until no brak�
ing effect can be felt when the wheel is
turned in a forward direction.
Caution:
The wheel brake must only be adjusted
by means of the adjusting bolt.
Reconnect the pull rods to the overrun
hitch and adjust so that there is no free play.
For this purpose, the drawbar of the over�
run mechanism must be completely
extended and the reversing must lever rest
on the drawbar.
As a test, apply the parking brake slightly

and check that the braking effect (in
the direction of travel) on the wheels
is the same on both sides. Check that
the individual brakes take effect at the
same time.
Caution:
Remove the locking device (< 4 mm
diameter pin) from the swivel cams.
