1.

    The inclusion of 2 spirit level vials per bracket (9) (one for the length of the caravan and one for width) 

provides the caravanner with accurate guidance in determining and adjusting the level of the caravan.

2.

    With the aid of the easy to use hydraulic jack, the level of the caravan can be adjusted simply and 

chocked accordingly with suitable platforms.

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.

3.

    Tighten release valve on base of jack by turning the valve (4) clockwise, 

do not over-tighten.

4.

    Insert the operating handle (5) into the handle socket (1) and pump the handle up and down until the 

slotted saddle (2) is aligned with the base of the chassis bracket (6/7).

CAUTION!

This jack is designed for lifting purposes only. After jacking,

always use safety stands to support load before making any

repairs. For your safety, do not overload beyond rated capacity

and do not adjust safety valve.

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. 2 sets of bolts, washers and 

nylock nuts are supplied for fixing the brackets onto both sides of the caravan.

3.

    Please refer to Diagram A. Working on the outside of the chassis face, line-up the holes on one of the 

outer brackets (6) and inner brackets (7) 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 

nylock nuts on the inside.

4.

    Screw on the nylock nuts and tighten securely. Ensure that the brackets are, as close as possible, at 90° 

degrees to the horizontal floor of the caravan. Careful fitting at the stage, ensures that the spirit levels will 

give a true reading to aid accurate levelling.

5.

    Repeat the procedure to fit the remaining brackets to the opposite side. Ensure that the bolts are 

sufficiently tightened up to 86Nm.

Only use the jack on a flat, hard surface.

Gloves should be used to avoid hand injury.
