							OPERATING INSTRUCTIONS FOR 
AL-KO SECURITY DEVICE FOR AKS 1300 STABILISERS
THESE INSTRUCTIONS SHOULD ALSO BE FOLLOWED FOR 
THE AL-KO SECURITY DEVICES FOR AK 160/300 COUPLINGS
INTRODUCTION
The AL-KO Security Device (Hitch Lock) helps protect against 
the following unauthorised operations: 
1) Uncoupling from the towing vehicle
2) Coupling onto another towing vehicle
3) Theft of the stabiliser/coupling from the trailer/caravan
MAINTENANCE
Clean strain bolt, locking bolts and the cutaway portion in the 
locking plates if they become dirty. 
A little grease may be applied but remove excess with a cloth so 
that only a thin film remains.
Operate the locking cylinder periodically, if the cover has not 
been used for a while. If the lock only operates with difficulty, 
spray the cylinder with WD 40 or comparable releasing fluid. 
For general lubrication use a Graphite based spray powder. 
SAFETY BALL
The safety ball is designed to be used in conjunction wth with the 
AL-KO Security Device. The Safety ball is inserted into the coupling 
area of the Stabiliser, before the AL-KO Security Device is locked 
into position. This prevents your caravan from being coupled to 
any other tow hook or smaller towball and being towed away.  
APPROVAL
This product holds full TUV approval.
 
WARRANTY
Product warranty is given in accordance with S10, Clause 1-7 of 
the General Terms of Business and is usually 12 months from

							With cross-type bolt fixing, do not forget to insert half moon 
shaped plates (Fig 7/Item 4) and section washer (Fig 7/Item 5).
For horizontal bolts, tighten with Allen Key (size 8),  as the nuts 
are fixed and cannot be moved.
For vertical bolts, tighten nut and torque as shown in Fig 9.
Secure gaiter with tie wrap.
Put security device on and lock. If the cover is difficult to put on or 
lock/unlock then you need to reposition the locking plates.  Loosen 
front bolt and the plates can now move laterally. Re-tighten bolts to

PROCEDURE
Push Gaiter onto the drawshaft followed by the AK160/300 
coupling or AKS 1300 stabiliser with spacers (Fig 8) if 
necessary, so that the fixing holes line up. If present, position 
the spacer sleeve in the draw shaft.
Fit parts as shown in Figs 6 or 7. If a spacer sleeve is in the draw 
shaft, thread this on as well. Push retaining pin (Fig 5/Item 1) 
through (with the bolt behind - horizontal or vertical). Shock 
absorber (damper), is threaded on.
FOR YOUR OWN SAFETY, PLEASE CHECK
To make sure the shock absorber (damper) is threaded on, push 
the draw shaft in and out. If you can feel resistance, then it is 
correctly positioned. Always insert horizontal bolts as shown in 
Figs 6 and 7. ie from right to left (when facing caravan) as this 
allows correct clearances. Always insert vertical bolt from top to 
bottom and re-use original shim used on the overrun.
