OPERATING INSTRUCTIONS 
MANOEUVRING
For easier manoeuvring (on campsites etc), pull the stabiliser  
lever to the ‘up’ position.
Please do not use the stabiliser lever as a manoeuvring 
handle. Please use the handles on the caravan or fit the AL-KO 
manoeuvring handle to your jockey wheel (available separately).
1. During opening or closing, the AKS must only be 
operated by one person.
2. Press stabiliser lever down by hand force only. DO NOT 
use your foot or an extension bar, this will damage the...

NOISES WHILST DRIVING
As a rule, the friction pads of the AKS 3004 do not make a noise 
during driving. Any clicking, creaking or squeaking noises that 
do arise may be due to the following:
a. Foreign bodies, dirt or exhaust particle build up between the 
friction pad and towball.
b. Dry operation of the drawshaft inside the overrun device.
c. A detachable towball which has too much play in the 
locking mechanism.
REMEDIAL ACTION
a.  Clean the towball and friction pads before each journey by 
lightly...

CHECKING THE EFFICIENCY OF 
THE SIDE 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 13/Item 1) down until 
resistance is felt (i.e. The friction pads are in contact with 
the ball but not yet under pressure).
3. Check the position of the arrowhead on the arm of the 
stabiliser. If it lines up with the two green lines then the 
friction pads are...

CHECKING THE EFFICIENCY OF THE 
FRONT/REAR FRICTION PADS
1. Couple the AKS 3004 stabiliser to the towball but do not 
activate the stabiliser.
 2. If a green indicator is visible (on the handle), then the 
AKS 3004 is in a new condition or the pads and towball 
are within the permissible limits (Fig 16/Item 2).
3. If only a red indicator is visible (Fig 17/Item 3), then this 
may have the following causes:
a. AKS 3004 is okay but the towball has reached the 
lowest limit of 49.61mm.
b. AKS 3004...

IMPORTANT MAINTENANCE & CLEANING ADVICE
1. The towball should be cleaned regularly to remove grease 
or other residue, to maintain the efficiency of the friction 
pads. The use of thinners, white spirit or brake cleaner is 
recommended for cleaning the towball and friction pads. 
2. If friction pads are contaminated, they should not be 
cleaned but replaced. 
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...

FAQS
STABILISER
CAN THE RED AND/OR GREEN INDICATOR 
BUTTONS BE REPLACED IF BROKEN/MISSING?
This is usually caused by catching the button with the hitch 
lock when fitting the hitch lock. The green section can in 
some circumstances be replaced. Please contact AL-KO for 
further advice.   
The red part cannot be replaced.
THE STABILISER ARMS KEEP LIFTING 
UP WHEN I TRAVEL.
The most likely cause is the handbrake handle catching on 
the stabiliser lever when braking.
Gently tease the handle away from the...

FAQS
WHEN TOWING I CAN HEAR 
LOUD CREAKING OR GROANING.
2 possible causes:
1 The incorrect towball could be fitted. Check your towball 
is compatible with your stabiliser, and if it isn’t replace 
it immediately. Failure to do so could result in your 
caravan becoming unhitched during towing. 
 The necessary clearances are outlined on page 4, and 
AL-KO recommends the AL-KO extended neck towball 
which complies to all the necessary specifications. 
2 Contamination may have built up on the friction...
