When the pins on the lifting links of the towing hook are
set into their holes (drawbar must be locked on the upper
position), the lift is locked in its uppermost position. In this
case the lift will not be lowered if the lever is moved to the
lowering position. Using this locking system ensures
safety when you have to do adjustments with the lift up.
When the pins are not used, they are kept in the holders
(A) which are on the lifting link rods.
WARNING: When using locking position of the lifting
links of the hitch, both lifting links must be locked.

Checks and Adjustments
2.1. Adjusting lifting links of trailer hitch
69---109
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 (on electrohydraulic linkage use the position
control knob, the transport height selector must be on
max 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.
On electrohydraulic models the lifting links may be
tightened when lifting with push buttons.
2.2. Checking locking of trailer hitch
69---110
10---14
mm
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
min 44 mm
69---127
DANGER! When the trailer hitch has worn
down to 44 mm from the thinnest part, it has
to be replaced.
