							OPERATING INSTRUCTIONS FOR 
AL-KO AKS 1300 STABILISER
RESTRICTIONS OF USE
Spare wheels fitted to rear door of vehicle, or vehicle with 
platforms etc:
1 The AKS 1300 Stabiliser is based on the latest regulations.  
This means the new DIN 74070 (dimensions of couplings) 
are  also adhered to.
2 The trailer coupling may only be connected to towing 
vehicles where the clearance for the stabiliser can be
 observed, in accordance with Directive 94/20 EC (DIN 
74058). If these clearances are infringed by special
 attachments, then the use must be checked separately.
3 Not suitable for use with overrun devices which revolve 
above 25°.
4 For Swan Neck towbars (fixed or detachable), refer to 
clearances on page 4.
5 This product is not suitable for use where the overrun has a 
reverse lock fitted, on the side (Fig 3).
6 For GB use, please use the AL-KO extended neck towball. 
WARNINGS
1 In accordance with EC Directive 94/20, couplings type A 
50-1 cannot be used (see Fig 1).
2 A bolted-in type ball coupling (Fig 2) is only permissible if 
the thread is locked.

REMOVAL OF EXISTING FIXING BOLTS
Before you start to remove the existing fixing bolts, please 
note that on most over-run assemblies, the shock absorber is 
secured by the fixing bolt (Fig 4/Item 2).
WARNING
The shock absorber (damper) extends independently. Enclosed 
with this box is a retaining pin (Fig 5) to aid assembly.
a Remove gaiter
b Loosen self-locking nut from hexagon cap bolt (Fig 4/1 Fig 4/2)
c Push or knock out hex. cap bolt (Fig 4/Item 1)
d Knock through retaining pin (Fig 5/2) with (Fig 5/1) & leave 
the pin in the shaft for centring the shock absorber (damper)
e Any spacers originally fitted must be re-used
PLEASE CHECK THE CONDITIONS FOR ATTACHMENT BY 
FOLLOWING THE STEPS LISTED BELOW
TOWING VEHICLE WITH TOWBALL ATTACHMENT
The equipment may only be used for connecting to towballs to 
(DIN 74058 or local equivalent), where the clearance below the 
ball, measured from the centre of the coupling point, is at least 
60 mm (Fig. 13). According to British Standards the prescribed 
rotation of ±25 o  will thus be achieved.

STABILISER LEVER CLEARANCES (FIG 7)
No component parts are allowed in the space marked X. The 
measurement of X  should correspond at least to the travel of 
the overrun equipment (as a rule 80 - 100 mm according to 
type).  Measurement is taken with a fully extended drawbar. 
AL-KO overrun equipment fulfils this requirement.
Coupling to Trailer Measurements (attachment hole 
dimensions B horizontal or cross) Please check dimensions 
of  your coupling (Fig 7) on your overrun equipment and also 
refer to table 1 for dimensional information.
ALL EC COUNTRIES
The installation is to be examined 
in conformity to the stipulations in 
Appendix 1, No.5.10, according to the 
demands of Appendix VII of Directive EC 
94/20. These installation and operating 
instructions are to be included with the 
caravan/trailer papers. 
GB - Installation only possible with special towball attached to 
towing vehicle. Towball type A50-X (included with this kit).
See regulations and restrictions of use on page 2.

Fig. 10/Item 2: Handwheel
Fig. 11/Item 3: Coupling Handle 
COUPLING/UNCOUPLING
When coupling or uncoupling, the stabiliser lever must be in 
the up position (open) and the handwheel (2) must be unwound 
until a slight resistance is felt (Fig 10).
WARNING  
Do not turn the handwheel against the stop by force.
OPERATING INSTRUCTIONS FOR 
AL-KO AKS 1300 STABILISER
COUPLING UP
Open coupling handle - to do this, pull the coupling handle (Fig 
11/1) in the direction of arrow. The coupling mechanism has 
an open position, i.e. as long as the AKS 1300 is not placed on 
the ball, the coupling handle will remain open. Place the open 
coupling onto the towball. The coupling handle should audibly 
click back into starting position. 
SAFETY WARNING
If the stabiliser is correctly coupled to the towball, then the 
green edge of the safety indicator is visible. The coupling 
mechanism is correctly positioned when the hand lever can no 
longer be pressed down even by hand.
If the AKS 1300 is not correctly coupled to the towball, then the 
trailer/caravan can become disconnected from the towing vehicle.

AL-KO AKS 1300 STABILISER
STABILISER UNIT
Starting Position: The AKS 1300 is connected to the towball.  
Turn the handwheel to the right (clockwise) (Fig. 12/1), until the 
torque limit can be heard and felt to ratchet. Press the stabilising 
lever (Fig. 13/2) down . The AKS 1300 is now functional. 
UNCOUPLING
Uncoupling of the trailer from the towing vehicle takes place in 
reverse order. Pull the stabiliser lever up, until the marking on 
the stabiliser lever (Fig. 13/Item 1) matches the marking on the
stabiliser cover (top end position of the stabilising lever). Turn 
the hand wheel in an anti-clockwise direction (left) until a slight 
resistance is felt. Open coupling handle and lift AKS 1300 from 
the towball of the towing vehicle.
Coupling and uncoupling can be made easier by use of the 
jockey wheel.
SAFETY TIPS
The AKS 1300 should only be operated by one person when 
coupling or uncoupling. 
WARNING
Never operate with foot or extension bar! The components will 
be overloaded and damaged (Fig 14).
When opening or closing the stabilising lever, care should be taken 
not to trap fingers between the lever and the coupling handle (Fig 
15). See grip areas (Fig 15). When applying the stabiliser lever 
some resistance should be experienced. Should this not be the 
case, then the handwheel may be jammed.

							OPERATING INSTRUCTIONS FOR 
AL-KO AKS 1300 STABILISER
IF NO STABILISING EFFECT IS FELT
The handwheel has been turned forcibly against the end top on 
opening. You should contact AL-KO on 01926 818 500.
IMPORTANT OPERATING FACTORS
The towball should be completely free of grease and other  
residue. Clean thoroughly with Thinners or Brake Cleaning fluid. 
HINTS
The surface of the towball must be free of grooving, rust and 
scratch marks, Otherwise increased wear and tear will occur. If 
pads are contaminated by paint or if they are glazed, they can 
be cleaned with 100-200 grain sandpaper. 
Painted towballs or similar coatings: In the event of the ball being 
coated, this must be thoroughly removed (with 100-200 grain 
sandpaper). Otherwise reduced stabilising effect, increased wear 
and damage to AKS 1300 components may occur.
During winter use, spay a tiny amount of de-icer onto the 
indicator button.  Ensure that this fluid does not come into 
contact with the friction pads. 
STABILISING UNIT
Should lubrication of the stabiliser unit parts become necessary 
then the following must be observed:
1 Clean all parts thoroughly.
2 Areas may only be covered with a thin film of grease (Fig 15 
& 16). Remove both friction pads (Fig 17) and lubricate the 
post only. Lever arm joint should also be lubricated regularly.
3 Use multi-purpose grease to DIN 51825 KTA 3 K (or equivalent).
WARNING
When lubricating - no oil or grease should be allowed to come 
into contact with the friction pads or onto the ball holding area. 
If friction pads are contaminated with grease, they should 
not be cleaned as this will have a reduced stabilising effect.   
Therefore friction pads should be replaced.

OPERATING INSTRUCTIONS FOR 
AL-KO AKS 1300 STABILISER
REPLACING FRICTION PADS
Loosen retaining ring (Fig 17/Item 1) with pointed object. Push 
out friction pad (Fig 17/ Item 2) from outwards to inwards. Only 
replace one pad at a time. Fit new pad, replace ball race and 
secure with a new retaining ring. Proceed in the same way on 
the other side. Remember, if any washers come away with the 
pad, please replace on the new pad.
GENERAL INFORMATION
MANOEUVRING BY HAND
Stabilising lever may not be used as a manoeuvring handle. 
Please use the handles on your caravan or the AL-KO 
manoeuvring handle which can be purchased separately to
attach to your jockey wheel. 
Failure to comply results in danger of overloading component parts.
 
NOISES WHEN DRIVING
The friction linings should not make a noise when driving. Any 
clicking, creaking, or squeaking noise arising, could be due to:
1 Foreign bodies or dirt between the friction pad and towball.
 Remedial action: Clean the towball and clean friction pads by 
lightly rubbing over the pad with sandpaper (100-200 grain).
2 Dry operation of the towball shaft in the sleeve of the 
overrun equipment.
 Remedial action: Lubrication of the sleeves through the 
grease nipples (use multi-purpose grease DIN 51825 KTA 
3K), additionally pull the gaiter off the overrun, towards the 
front and grease all of the exposed drive shaft.
3 The towball on the towing vehicle has too much play in the 
locking mechanism (if detachable). 
 Remedial action: Go to specialist workshop. Have the 
towball checked for damage. If necessary change towball or 
if permissible re-lubricate locking mechanism.
