4 Lock nut
The locking mechanism must be adjusted using a semi-trailer with-
out forced steering with an unworn king pin as described below:
Park the vehicle on flat, firm ground and uncouple the trailer
Undo the lock nut (4)
Unscrew the adjusting screw (3) by approx. 15 turns
Couple the semi-trailer up, if necessary lightly tapping the han-
dle (1) in the closing direction A to bring the locking bar into its
limit position
Release the handle (1) (lift the safety latch - see figure G50/20
in section 4.3) swing into position B and hold (get someone to
assist).
Tighten the adjusting screw (3) again until the handle (1) starts
to move (have an assistant check this)
To set the recommended basic play of 0.3 mm, tighten the ad-
justing screw (3) by a further 1½ turns and secure it with the
lock nut (4)
Apply the semi-trailer brake
Move off with the tractor and check the maximum play in the
locking mechanism.
ADVICE!
If there is still excessive play, the wearing ring and the
lock jaw must be replaced as described in the repair in-
structions.
