Operating Instructions
Note:
The lock nut is tightened and loosened without additional tools (i.e. by hand).
The supplied wrench is provided to assist, if necessary, in loosening the lock nut.
The mechanism is to be checked on a regular basis.
To ensure proper functioning and a long dependable operating life of the moving parts
in the receiver pipe, the tow bar should be always be removed and the sealing plug
fitted during journeys without a trailer.
If the visibility of the licence plate or the lights is impaired by the towing hitch, the towing
hitch must be removed when a trailer is not being towed.
Always grease the tow bar before inserting.
The tow bar (even when not installed) must always be in the vehicle.
Attach the sign provided to the vehicle near the support tube or on the inside of the
luggage compartment in a clearly visible location.

1.) Turn sealing nut

ring and pull out sealing plug.
2.) Insert tow bar into receiver pipe as far as it
will go. The red ring marking must no longer

The lock nut must be screwed on far enough
that the coiled spring can pass through the
safety bore
(directly in front of the lock
nut)
through
the receiver pipe and tow
bar
without difficulty (see illustration).
Only when these conditions are fulfilled is
the tow bar properly locked in place and
may it be used.
If the coiled spring does
not fully
protrude
through the safety bore, the tow bar is not
properly locked in place and, because of the
associated accident risk, it must not be
used under any circumstances.
To determine and rectify possible damage,
consult an appropriate service center.
