Handling (Operation)
Uncoupling and coupling
Note: The handle of the ball hitch and the handbrake lever must not be used as a
manoeuvring aid. There is a risk of damage to the internal components!
The coupling head (ballhead hitch) on your BPW chassis is designtested. The maximum
load supported at the coupling point must be complied with.
Lower the jockey wheel to the ground. Reverse the car up to the trailer or, in the
case of a small trailer, manoeuvre the trailer up to the car's trailer coupling.

Ballhead must be free
from oil and lubrication
Coupling:
Place the open ballhead hitch on the ballhead of the
towing vehicle (greasefree). If pressed simultaneously
downwards  usually the support load is sufficient  the
ballhead is closed automatically and locked securely.
The stabilising device is activated by moving the operating
lever down to the stop, i.e. opposite of direction of travel.
In doing so the spring element is tensioned, thus generat
ing via the friction elements the contact pressure force
onto the ballhead of the coupling. Connect the break
away cable and electrical plug to the towing vehicle.
Raise jockey wheel fully upwards and secure. Release
parking brake before setting off.
Visual check: the ballhead should no longer be
visible in coupled condition.
Noises may occur during driving as a result of friction
between the elements and the ball hitch. However, these
noises do not have any effect on the function of the
trailer ball hitch.
Uncoupling:
Lower the jockey wheel down.
Disconnect breakaway cable
and electrical plug. Lift the
operating lever in opposite
travel direction to the open
position. Lift the safety cou
pling. Secure the trailer by
means of a wheel chock
and/or by applying the park
ing brake.
