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.

2.2 Closing coupling manually

(e.g. for tow-rope)
x Raise coupling pin with suitable tool

or

x Strike hand lever knob briefly in opening direction with heel of

hand.

3. Maintenance

3.1 Care

x Lubricate coupling pin, support ring and drawbar eye with

heavy-duty grease (EP3) which is waterproof if possible before
first use and after extended period in use.

x Low-maintenance automatic unit has a grease reservoir

(regular greasing unnecessary, please see below for repair
information).

x Lubricate lower funnel bearing (F) and bearing (L) with EP3

(intervals: 6 months or 50.000 km), see Fig. 4

x Close coupling before cleaning with high-pressure washers

(see para. 2.2).

x After cleaning, relubricate coupling pin and support ring

with EP3.

Please note the following when carrying out repairs on coupling
(e.g. changing coupling pin):

x Remove as much of old grease as possible.
x Relubricate with multi-purpose grease NLGI 2.
