Attach the breakaway cable so that cornering
is possible without problems.
The breakaway cable must not wind itself
around the support wheel.
When fitting the breakaway cable, comply
with country-specific regulations.
Jockey wheel
Make sure that the support wheel is seated
firmly.
Parking
If the trailer is uncoupled from the towing ve-
hicle, then the following must be done:
the parking brake must be engaged.
the trailer must be secured with two addi-
tional chocks.
the support wheel must be lowered and
locked.
When parking or laying up the vehicle/trai-
ler combination, engage the trailer's parking
brake.
CAUTION!
The trailer may roll back 25 to 30 cm un-
til the full force of the brake takes effect.
When laying up the trailer, ensure suffi-
cient clearance.
CAUTION!
When you apply the parking brake en-
sure that it functions correctly.
Incorrect function may be noticeable by the follo-
wing:
Noticeable loss of force
The handbrake lever does not move smoothly
The handbrake is difficult to move
Loose components
ASSEMBLY
CAUTION!
Risk of accidents!
In an emergency, it must be ensured
that after the breakaway cable has been
used to engage the handbrake lever
(handbrake in the closed position), the
lever remains accessible. If the hand-
brake were to make contact with the
road surface, the functioning of the emer-
gency brake could no longer be assured.

The attachment to the vehicle with regard
to height-adjustable support equipment (sup-
port wheel) for imposed loads greater than
50 kg as well as the setting of the coupling

ties.
2. Always pull the handbrake firmly past the
dead centre point (5-1).
