The lifting links must always have a certain amount of clearance when the rear
linkage is in its upper position. However, they must be adjusted in such a way
that the pick-up hitch is securely locked by the pawl, even when the towing hook
is loaded.
1. Raise the rear linkage to its upper position.
Use the lifting/lowering switch.
2. Check the adjustment by moving the lifting links manually.
The adjustment is correct when the links are slightly tensioned. When the
linkage is lowered, the towing hook is locked positively by the pawl.
3. Make sure that the spring returns the pawl completely.
4. If necessary, adjust the length of the links by removing the cotter at the upper
end of the links and turning them until the correct length is obtained.
The link shortens when turned clockwise and extends when turned
anticlockwise.
5. Check that both lifting links are of the same length after the adjustment.
Correctly adjusted, the lifting links ensure that the rear linkage can be raised to its
uppermost position. The pick-up hitch is locked when the linkage is lowered to
the point where the hitch rests on the pawl. This prevents unnecessary loading
on the hydraulic pump and overheating of the oil.
