Maintenance
SAFETY WARNINGS
1. In accordance with EC Directive 94/20,
couplings of type A 50-1 cannot be used
(see Fig. 21), your warranty will be invalid
if this type of towball is used.
2. For UK use, please use the extended
neck towball (type A50-X).
3. A bolted-in type ball coupling (Fig. 22) is
only permissible if the thread is locked or
welded.
4. The AKS 2004 cannot be used with a
laterally attached reversing lever, on the
left side, when facing direction of traffic.
5. The towball must be free from grease,
paint and other residue, otherwise the
stabilising effect will be greatly reduced.
6. If friction pads become contaminated
with grease, they should be replaced.
7. The AKS 2004 should only be operated
by one person, when opening or closing
the handle, to reduce injury risks.

Coupling
Pull the coupling handle (Fig. 25/Item 1) up
in the direction of arrow. The coupling
mechanism has an open position ie. as long

the handle will remain open. Put the opened
coupling onto the clean towball. The handle
must now make an audible click and return
