3. The surface of the towball must be free of
grooves, rust or seizing marks.
4. Towballs coated (with paint or similar)
must have this surface completely
removed (use 100 or 120 grain emery
paper). If this is not done, increased
towball wear will occur and may cause
damage to the AKS 3004 components.
5. In Winter, carefully spray only the visual
indicator with de-icer.
lubrication
Should lubrication of the stabiliser parts become
necessary, then the following must be observed.
a) Clean all parts thoroughly.
b) Areas may only be covered with a thin film
of grease (Fig. 38).

c) Use multipurpose grease DIN 51825 KTA 3K.
Warning: When lubricating, ensure none gets
into the friction pad or towball holding area.

overrun devices
In the importance of Safety, please familiarise
yourself with the operation of this overrun
device BEFORE using your caravan/trailer.
safety precautions
When parking your tow vehicle and caravan/
trailer on site, you must apply the caravan
handbrake. If the unit is parked but
disconnected from the tow vehicle, it is strongly
recommended that each wheel is chocked
using AL-KO or suitable wheel chocks.
If a ‘detachable’ type drawbar is fitted
(as with catering trailers). the drawbar must
not be removed from the trailer with the
hand-brake applied.
caution: please note when parking
the caravan/ trailer, the wheelbrake
auto-reverse mechanism will allow the
caravan/trailer to travel backwards
for approximately 25 cm (please allow
sufficient clearance when parking) .
operation
AL-KO overrun devices are a mechanical type,
using a hydraulic damper.
coupling up
