DANGER
If the coupling pindrops out during towing, the trailer
will work loose and can no longer be controlled.
There is a risk of accident!
A protruding safety handle means that the tow bar
eye has not been coupled correctly. The trailer
must not be towed in this condition.
– Make sure that the control pin does not protrude
from the control bush.
– Repeat the coupling process if necessary.
– Remove any items used to prevent the
trailer from rolling away.
– Tow the trailer.

Towing trailers
– Drivers who are towing a trailer for the first
time must practise driving with a trailer in a
suitable area.
– When passing through narrow road areas
(entrances, gates etc.), observe the dimen-
sions of the trailer and load.
– When towing multipl
e trailers, ensure
a sufficient minimum
distance to fixed
installations when
turning and cornering.
The permissible length of the trailer trains
depends on the roadways to be driven and
may need to be determined during the test
drive.
It is the responsibility of the operating com-
pany to instruct the drivers regarding the
permissible number of trailers and, where
required, any additional speed reductions on
individual sections of the route.
