Warning!
Danger of injury by the heavy ball hitch.
f When removing the ball hitch, hold it in such a
way that your hand cannot be pressed onto the
road surface.
2. Hold ball hitch E with your left hand. Pull
handwheel D out in arrow direction 1 and
then, with the handwheel still pulled out, turn it
as far as it will go in arrow direction 2.
Hold handwheel in this position.
3. Remove ball hitch from the mounting tube in
arrow direction 3.
Release handwheel.
The ball hitch has now been tensioned and can
be stowed in the tool box in this state.
4. Always insert the plug into the mounting tube
to protect against soiling.
Tip on driving
The ball hitch must always be removed when
driving without a trailer.
Care instructions
The ball hitch and mounting tube must be kept
clean to ensure proper functioning.
Remove the ball hitch and insert the plug before
cleaning the vehicle with a high-pressure cleaner,
steam cleaner or similar device.
The ball hitch must not be cleaned with a high-
pressure cleaner, steam cleaner or similar device,
because this would wash out the lubricating
grease inside the ball hitch.
