Ensure front (towing eye) section is set level
When raising towing eye, set rear joint first, then front joint.
When lowering towing eye, set front joint first, then rear joint.
After setting, fully tighten each joint by hand and then tighten fur-
ther to the next pin. Refit the pin.
When parking always use the handbrake and, if necessary,
suitable wheel chocks.
Make sure wheels, tyres and tow bar connectors are in safe
operating condition and tow bar is properly connected before
towing.
Safety chains / connections and their adjustment
The legal requirements for the joint operation of the
breakaway cable and safety chains are as yet unidentified by
71/320/EEC or UK regulations. Consequently we offer the
following advice / instructions.
Where brakes only are fitted:
a) Ensure that the breakaway cable is securely coupled to the
handbrake lever and also to a substantial point on the towing
vehicle.
b) Ensure that the effective cable length is as short as possible,
whilst still allowing enough slackness for the trailer to articulate
without the handbrake being applied.
Where brakes and safety chains are fitted:
a) Loop the chains onto the towing vehicle using the towing
vehicle hitch as an anchorage point, or any other point of similar
strength.
b) Ensure that the effective chain length is as short as possible
whilst still allowing normal articulation of the trailer and effective
operation of the breakaway cable.
Where safety chains only are fitted:
a) Loop the chains onto the towing vehicle using the towing
vehicle hitch as an anchorage point, or any other point of similar
strength.
b) When adjusting the safety chains there should be sufficient
free length in the chains to allow normal articulation, whilst also
being short enough to prevent the towbar from touching the
ground in the event of an accidental separation of the towing
vehicle from the trailer.
