3.3 Locking brake facilities
The components of the brake facilities, particu-
larly the overrunning equipment, wheel brakes
and towbar were checked in accordance with
the appropriate EU Guidelines and may only be
used in a licensed combination.
If you alter or modify any components of the
brake facilities, the operation permission loses
its validity. Modifications may only be made with
the manufacturer's permission.
Noises while driving
Generally, the friction pads of the AKS 2004/AKS
3004 do not make noises! Any clicking, creaking
and screeching noises could be caused by the
following:
• foreign matter or dirt between the friction pad
and the drawbar ball
• dry operation of the drawbar/tie rod in the
bushings of the overrun coupling
• drawbar ball on the base vehicle can be re
-
moved and there is too much tolerance in the
lock mechanism
• surface coating has not been removed from
drawbar ball (grease, galvanised, Dacomet,
varnish, KTL or any other coating)
To eliminate
• Clean the drawbar ball and the friction pads
by lighting sanding the pads with sandpaper
(grain: 100-120).
• Use the lubricating nipple to grease the bu
-
shings. In addition, pull the gangway bellows
on the overrun coupling off towards the front
and grease all of the exposed drawbar (Fig.
25).
• Lubricant: multi-purpose grease in accor
-
dance with DIN 51 825.
• Take the camper to an authorised specialist
company. Have the contact surfaces checked
for damages and the lock mechanism che-
cked that it is functioning correctly. If neces
-
sary, replace the drawbar ball or, if permitted,
regrease the lock mechanism (please refer
also to the operating manual for the remova-
ble drawbar ball).
