AL-KO COUPLING
THE AL-KO AKS STABILISER AND
COUPLING
The trailer coupling may only be connected
to towing vehicles where clearances for the
stabiliser can be observed, in accordance
with EC Directive 94/20 (DIN 74058). If
these clearances are infringed by special
attachments, then the use must be checked
separately.
The area above the towball of the vehicle
must be free from vehicle components or
attachments (A) (e.g. spare wheels, platforms
etc.)
The clearance for the stabiliser lever must be
at least 330mm (B) + the stroke movement
(D) (85mm-100mm), which equates to 440mm
when used in conjunction with an AL-KO
overrun.
Max. 50mm (C) clearance between the centre
of the towball and top of the overrun assembly
or fairing, to ensure both coupling handle and
stabiliser lever do not foul on operation.
Maintain the same clearances for other
manufacturers’ overrun assemblies.
May not be suitable for use with overrun
devices which can revolve above 25° (Fig 2) or
BPW overruns fitted with gas strut handbrakes
from 2001 model year onwards (If in any doubt
about usage consult your manufacturer).
Swan neck towbars (fixed or detachable) are
suitable for use with the AKS 3004 providing
they comply to EC Directive 94/20 and have
the required minimum 60mm clearance,
measured from the centre of the towball.
FIG. 1.
Pull the coupling handle (Fig. 2/Item 1) up
in the direction of the arrow. The coupling
mechanism has an open position, i.e. as long
as the AKS 3004 is not placed on the ball,
the handle will remain open. Put the opened
coupling onto the clean towball. The handle
must now make an audible click and return to
the flat position.
