AL-KO COUPLING
FIG. 2.
The coupling is correctly engaged
when the green edge of the safety
indicator button is visible (Fig. 4/Item
3.)
Always ensure that the jockey wheel is fully
raised and secure before commencing any
journey.
FIG. 4.
STABILISER UNIT
To operate the stabiliser (once coupled to the
towball), simply press the stabiliser lever down
as far as it will go (Fig. 4/Item 2).
FIG. 5.
UNCOUPLING
Pull the stabiliser lever handle up as far as it
will go, lift the coupling handle and lift the AKS
3004 from the towball. With larger nose loads,
coupling and uncoupling can be made easier by
using the jockey wheel to assist lifting.
The friction pads are pressed against the
towball and hence generate a stabilising/
damping force. These pads are therefore
subject to wear over time; however they will
have a long service life (circa. 30,000 miles),
provided they are well maintained and kept
free of grease/dirt.
Having lowered the jockey wheel to the ground,
operate the handle as previously described.
Lift the coupling clear of the towing ball either
manually or by operating the telescopic jockey
wheel.
Checking the efficiency of the left/right friction
pads:
1. Check that the stabiliser is correctly
coupled by ensuring the coupling handle
is fully down and the red indicator button
is in the raised position.
2. Push the stabiliser lever (fig.5/item 1)
down until resistance is felt (i.e. the
friction pads are in contact with the ball
but not yet under pressure).
