Operating Instructions for
AKS 2004
REGULATIONS
1. The AKS 2004 must be used in
conjunction with 50 mm dia. towballs
which conform to EC Directive 94/20 (DIN
74058 or local equivalent).
2. Suitable for attachment to drawbars or
approved overrun braking equipment for
single (and tandem axle) caravan/trailers,
with a minimum weight of 200 Kg and a
maximum permissible weight of 2000 Kg.
3. EC design approval has been given to the
AL-KO AKS 2004 coupling under permit
No. e1*94/20*0930*00.
RESTRICTIONS OF USE
1. The trailer coupling may only be
connected to towing vehicles where the
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.
Clearances for Stabiliser Handle
(Fig. 19)
The area above the towball of the vehicle
must be free from vehicle components or
attachments (A) (eg spare wheels,
platforms etc.)
The clearance for the stabiliser handle
must be at least 330 mm (B) + the stroke
movement (D) (85mm-100mm), which
equates to 440 mm when used in
conjunction with an AL-KO overrun.
Max. 50 mm (C) clearance between the
centre of the towball and top of the
overrun assembly or fairing, to ensure
both coupling handle and stabiliser
handle do not foul on operation.
Maintain the same clearances for other
manufacturers’ overrun assemblies.
2. Not suitable for use with overrun devices
which can revolve above 25 (Fig. 20).
3. Swan Neck towbars (fixed or detachable)
are suitable for use with the AKS 2004
providing they comply to EC Directive
94/20 and have the required minimum 60
mm clearance, measured from the centre
of the towball (Fig. 20).
