2. Operation
2.1 Hitching
The regulations of the relevant employer’s liability insurance
association must be observed when hitching and unhitching.
x Push hand lever upwards until it engages when hitching.
x Check whether funnel is locked.
x Release brake on front axle of full trailer (Fig. 2).
x Set drawbar eye to height of coupling point (centre of
funnel).
x Slowly reverse tractor unit.
When hitching a central-axle trailer (Fig. 2) please note the
following:
x Drawbar eye must mate with centre of funnel. If not, this can
result in damage to funnel, drawbar eye, automatic unit and
support unit.
Check
Caution:
After every hitching operation it is essential to check that
the coupling is engaged as required by regulations.
The check pin must be flush with its guide bush after hitching
(see Fig. 3).
If the check pin protrudes from its guide bush (this can also
be established by touch if dark), this indicates that hitching has
not been carried out correctly, and that you are at risk
of an accident.
The truck may not be driven with the trailer in this condition!
Remedy:
– Advance tractor unit approx. 1 m and then reverse again.
– Check again.
In-cab status indicator upgrade kit available for retrofitting.
