ADJUSTMENT OF THE LIFTING DRAW-BARS OF THE HITCH FOR A SINGLE-
AXLE SEMI-TRAILER
Raise the hydraulic arms to the upper - transport position with the position control
selected and the vibration compensator off.
Screw the nuts on the adjustable draw-bars towards the guiding pipe without any
play.
Tighten the nuts by another 3.5 turns.
Check whether it is possible to tilt off the supporting hooks freely.
By lowering and repeated lifting of the hydraulic arms to the transport position check
whether the engine does not tend to “stall" at the idle speed - the relief valve of the
hydraulic pump must not be in operation.
Then, lower the arms slightly.
ADJUSTING THE BOWDEN CABLE
It is performed if the carrier with the tow-
ing hook is in contact with the supporting
hooks. The Bowden cable must be ten-
sioned to avoid any play of the control
lever in the cab. Then, the cable is se-
cured against loosening with a nut.
