1.  The chassis brackets are suitable for AL-KO caravan chassis manufactured after 1992 that have pre-drilled mounting holes already on the chassis.

2.  The chassis brackets should be mounted, behind the axles on both sides. 

3.  2 sets of bolts, washers and nyloc nuts are supplied for fixing the brackets onto both sides of the caravan. 

4.   Working on the outside of the chassis face, line-up the holes on one of the brackets (6) with the pre-drilled chassis holes and insert the bolts with washer through the apertures.

Note: The bolt heads and washers must be on the outside of the chassis with the nyloc nuts on the inside. 

5.  Screw on the nyloc nuts and tighten securely. Ensure that the brackets are, as close as possible, at 90º degrees to the horizontal floor of the caravan. The use of a spirit level is advised.

6.  Repeat the procedure to fit the remaining bracket to the opposite side. Ensure that the bolts are sufficiently tightened up to 86Nm. 



1.   Before jacking, the caravan must be attached to the towing vehicle and the handbrake must be applied on both the caravan and the vehicle. 

2.  Chock the caravan wheels (back & front) on the opposite side to the wheels to be lifted/changed. Place the jack in-line with the bracket on the side of the caravan to be raised. If the ground surface is soft, a board, plank or similar should be placed underneath the jack.

Warning Only use the jack on a flat, hard surface.

Warning Gloves should be used to avoid hand injury.

5.  Once correctly aligned, continue to turn handle to raise the caravan to the required height. 

6.  To lower the caravan, secure the Handle (8) to the Connection Point (1) keeping the handle  level turn anti-clockwise until caravan is completely lowered. 


Caution Do not raise the caravan more than necessary; only raise until the wheel is sufficiently clear of the ground. 

Caution Do not lie underneath the caravan whilst it is jacked up as this could result in serious injury. 



1.  Do not use the jack if damaged.
