WARNING: When using locking
position of the lifting links of the hitch,
both lifting links must be locked.
2. Checks and Adjustments
2.1. Adjusting lifting links of trailer hitch
The lifting links should always have a certain
amount of clearance when the hydraulic lift is in its
upper position. However, they must be adjusted in
such a way that the trailer hitch is securely locked
by the pawl.
Before adjusting, raise the hydraulic lift to its upper
position. Check the adjustment by moving the lifting
link by hand. Adjustment is correct when the link
moves loosely. Adjust if necessary by turning the
cotter at the upper end of the links until a suitable
length is obtained. Check that both lifting links are
the same length after adjustment.
Correctly adjusted lifting links ensure that the
hydraulic lift can be raised to its uppermost position.
The trailer hitch is locked when the lift is lowered so
far that the hitch rests on the pawl, thereby
preventing unnecessary loading on the hydraulic
pump and overheating of the oil.
2.2. Checking locking of trailer hitch
Make sure that the spring returns the pawl fully
home. When the pawl is turned upwards the trailer
hitch should move up 10-14 mm.
2.3. Check wear of the trailer hitch
WARNING: When the trailer hitch
has worn down to 44 mm from the
thinnest part, it has to be replaced.
