FIGURE 5.1

Lifting jack support point

(1) wheel axle, (2) U bolt, (3) lower frame

Preparation procedures

Hitch trailer to tractor, braking tractor with parking brake.

Park tractor and trailer on hard level ground.

Tractor must be placed to drive forward.

Place securing chocks under one trailer wheel. Ensure that trailer shall not

move during inspection.

Raise the wheel (opposite to the side where chocks are placed).

The lifting jack should be placed between U bolts (2) - figure (5.1)

securing axle (1) to shock absorber leaf springs, or as near as

possible to leaf spring mounting. Recommended support points are

marked with arrows. Lifting jack must be suitable for the weight of

trailer.
