For safety reasons, the spare parts for
heating devices must conform with
the manufacturer's instructions. They
must be installed by the manufacturer
or an authorised representative.
Coupling ball on base vehicle
Ensure that the coupling ball meets the required
dimensions and is undamaged, clean and free of
grease. When using dacromet-coated (dull silver
anti-corrosion coating) as well as lacquered cou-
pling balls, the coating must be removed com-
pletely with sandpaper (200-240 grain) so that
it does not create deposits on the friction lining.
The metal surface of the coupling ball must be
bright. A damaged or dirty coupling ball causes
increased wear of the friction linings; a greasy
one greatly diminishes the stabilization effect.
Thinning solvents or spirit are both suitable for
cleaning.
12.2 Drawgear
The camper's turning rod spring
axle unit is equipped with compact
wheel bearings. The cylinder hub,
compact bearings and axle nuts
form a closed unit. The compact
bearings are free of maintenance
due to their special grease.
The wheel brake may never be
repositioned on the xing lock or on
the yoke end of the bars!
Only reposition the wheel brake on
the self-securing stationary hexago-
nal nut!
You can nd further guidelines in
the operating instructions from the
axle supplier.
