Tow Bar Removal and Installation

ring.

Tow bar installation
1.) Turn sealing nut counterclockwise to stop
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
be visible.
3.) Tighten lock nut by turning clockwise.
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.
