ADJUSTMENT OF THE RELEASING
BOWDEN CABLE
The hitch is in the working position. The
Bowden cable must be under such ten-
sion so that the control lever in the cab
has no clearance. If the Bowden cable is
not tensioned sufficiently, adjust it by
means of the adjusting screw (1) by
screwing on or off. Lock the adjusting
screw with the lock nut (2) after finishing
of adjustment.
