Coupling
NOTE
The trailer coupling RO 244 is intended for a
tow-bar eye in accordance with DIN 74054
(bore diameter 40 mm) or DIN 8454 (bore
diameter 35 mm)
– Take measures to prevent the trailer from
rolling away, e.g. use wheel chocks.
– Push the hand lever (4) upwards and open
the tow coupling.
CAUTION
When being coupled, the tow-bar eye must engage
in the middle of the coupling jaw. Failure to follow
these instructions could result in damage to the
coupling jaw or to the tow-bar eye!
– Ensure that the tow-bar eye enters the coupling
jaw centrally.
– Slowly move the truck backwards.
DANGER
If the coupling pin works loose during towing, the
trailer will become loose and uncontrollable. This
causes a risk of accident!
– Ensure that the coupling pin is engaged cor-
rectly.
– If it is not, repeat the coupling procedure.
– Remove any items used to prevent the
trailer from rolling away.
– Tow the trailer.
Uncoupling
– Take measures to prevent the trailer from
rolling away, e.g. use wheel chocks.
– Push the hand lever upwards.
– Slowly drive the truck forward until the
tow-bar eye and towing jaws are separated.
– Close the tow coupling.
