Changing the friction pads
It is very easy to exchange the friction pads
j
when they are
worn out. Messrs. Winterho oer a corresponding set of spare
parts. Please note the detailed instructions for assembly in the
manufacturer's spare part kit.
Noises
Certain noises can occur during towing your caravan; these
noises, however, have no inuence on the operative eectiveness
of the stabiliser hitch.
Possible causes of these noises can be:
1. a painted (dacromet coated) ball on the tow vehicle.
2. A galvanized or varnished tow ball on the tow vehicle.
3. A damaged, rusty or dirty tow ball on the tow vehicle.
4. dirty friction pads
j
on the stabiliser hitch head.
5. the towbar or brake rod in the linings of the overrunning
equipment are running dry.
Hints
For 1., 2. 3. and 4.:
Sand down the surfaces of the tow ball and clean them with a
thinning solvent or spirit.
for 5:
Use a lubricating nipple to grease the linings. Pull back the shock
absorber and grease the bare hitch shaft.

12.3 Brakes
Initial inspection
The brakes must rst be inspected after you have driven 500 km.
Inspections must be documented in the KNOTT service manual by the
authorised specialist who carries out the inspection. A documented
report is just as much a prerequisite for any possible guarantee claims
as is the compliance with the regulations for maintenance and upkeep.

After exchanging the brake pads, drive the rst 100 km
carefully, because the full brake force has not yet been
reached.
