6 Commissioning
►Carry out the following steps to drive with a trailer.
The towed trailer must always be approved and free of
defects!
Commission on solid, stable and level ground. Do no ob-
struct the trac on the roads. Do not impede road users
/ people and do not expose them to risks.
►Posion towing vehicle in front of the trailer.
- Trailer should be aligned with the towing vehicle
(in a straight line).
►Secure the towing vehicle to prevent it from rolling away.
►Release hand brake on the trailer (if present).

Operang Instrucon Manual V 2019/01 13/56
6.1 Hand brake without push buon
Funconal explanaon
• A hand brake (parking brake) is designed to prevent the
trailer from rolling away.
• Braked trailers have an overrun device with brake linkage
and brake compensaon.
• Unbraked trailers do not have a hand brake / parking
brake.
• The hand brake without a push buon needs to be moved
beyond a ratchet point.
WARNING
Releasing hand brake on unsecured trailer!
The trailer could start moving spontaneously - risk of
impact!
►Couple your trailer to the car.
►Release the hand brake once your trailer is secured with
wheel chocks.
Driving with the hand brake applied / not com-
pletely released!
The brake shoes could block the wheels - Risk of snak-
ing / accidents! The brakes get hot.
►Make sure that the hand brake is completely released
before driving o.
CAUTION
Operang the hand brake!
You could pinch / crush hands / ngers on the draw-
bar / ball head.
►Operate the hand brake slowly and carefully.
►Make sure that your hand and body are outside the
crushing / movement area.
Engaging the hand brake
Engaging the hand brake
1. Hand brake lever, engaged / top
2. Spring mechanism, extended
3. Jockey wheel (in parking posion)
►Wind down the jockey wheel (3) unl it reaches the oor.
►Pull up the hand brake lever (1) beyond the resistance
point so that the brake is fully applied.
►Push the trailer back slightly.
The spring mechanism (2) fully applies the hand brake.
CAUTION
Uncontrolled movement of the trailer when
the hand brake is applied!
Trailer could roll back approx. 25-30 mm when uncoupled unl
the full braking force is applied.
►Always apply the hand brake completely - if applicable,
push the trailer backwards slightly so that the full braking
force is reached.
►When parking your trailer, make sure there is enough
space behind it.

6.3 Trailer safety
Funconal explanaon
• Unbraked trailers (up to 750 kg) are ed with an arrester
cable.
• The arrester cable prevents the trailer from coming
uncoupled from the car in the event of the trailer coupling
disconnecng.
• Braked trailers (from 750 kg to 3500 kg) are ed with a
safety cable.
• In the event of the trailer coming unhooked, the safety
cable will trigger automac braking.
Driving without the arrester / safety cable aached is
prohibited by law!
Aaching the arrester / safety cable incorrectly is dan-
gerous and can result in nes in other countries!
Make sure the safety cable loop is suciently long to
allow cornering.
State of technology:
The safety cable may not be laid in a loop over the trailer cou-
pling. Where technically possible, it should be aached through a
ring or an exisng drilled hole in the coupling.
The snap hook on the safety cable is hooked into the pre-mount-
ed ring on the body, thus securing the trailer.
The car coupling as a mechanical coupling device must be state of
the art (Direcve ECE-R55).
The manufacturers of brackets must include aachment points
for secondary couplings (arrester / safety cable) or provide devic-
es which ensure that the trailer comes to a standsll in the event
that it comes uncoupled.
Pay aenon to the safety informaon and operang
instrucons from the manufacturer of the trailer
coupling on the car.
Driving with arrester / safety cable incorrectly aached!
The arrester / safety cable could detach from the ball head while
driving. If it came uncoupled, the trailer would be unsecured and
can't be braked - risk of accidents!
►Before seng o, check that the arrester / safety cable is
correctly and securely hooked into or threaded through a
xed ring / drilled hole / mechanical device - tying a loop
around the ball head is inadequate!
►If necessary, retrot an addional aachment device for
the arrester / safety cable if you have an older model
coupling (according to Direcve EEC 94/20).

6.4 Coupling / uncoupling the trailer
Funconal explanaon
• A coupling head is used on car trailers ed with a
Ø 50 mm ball head mounng.
• Always note and observe the maximum drawbar load and
trailer load of the ball head coupling.
Impact risk during coupling process!
Body parts in the area around the coupling may be
crushed or struck during the coupling process.
►Manoeuvre the towing vehicle carefully towards the
trailer.
►Make sure that no one is standing in the area
around the coupling.
► If necessary, arrange for an assistant to help
manoeuvre the vehicle using hand signals.
Operate the coupling head!
Your hands / ngers may be crushed between the
coupling head and ball head coupling on the car.
►Always hold the coupling by the handle.
- Do not grasp the ball mounng (spherical cup) from
below.
►Hold the drawbar / draw tube / handle when manoeu
vring the trailer.
►Only release the hand brake once the trailer is securely
coupled.
►Remove the wheel chocks.

5. Plug lock (an-the device)
The ball head on a car trailer coupling as well as the
coupling head on the trailer are subject to wear and tear
during operaon. This depends on the driving style as
well as adhering to regular maintenance of the ball head
and the trailer coupling. The dierent wear indicators on
the coupling head are there for your safety. These
display the status and wear of the ball head and the
coupling cup / spherical cup.
Driving with a worn coupling head!
Trailers can become detached, skid or p over while driving - risk
of accident!
►Do not drive with a worn / dirty coupling head.
►Before seng o, make sure that the coupling head
has clicked into place and the safety indicator is in the
green / posive area.
►A ball head on the car coupling with a diameter of less
than 49 mm needs to be replaced.

►Before connecng up your trailer for the rst me, make
sure that the car trailer coupling is aligned with the cou
pling head on the trailer:
• Height of both couplings
• Design of the car coupling
• Electrical connecon (plug: 7 or 13-pin)
Only to be used with ball head coupling according to
Direcve 94/20/EC or ECE R55 with a 50 mm Ø ball

Limited swivel range!
Short / incorrect car couplings can limit the necessary swivel

WARNING
The height of the coupling head
Coupling heads for trailers are built to DIN 74058 or ISO
1103 with a height of 430 ± 35 mm.
►Do not drive with a trailer which is at an extreme angle to
the car (or lted forwards or backwards).
The ball head must be greased to prevent premature
wear and the formaon of grooves on the ball head and
in the coupling housing (spherical cup).
Trailer at an angle!
The required swivel range is limited / increased coupling wear /
road handling is impaired - trailer could come uncoupled.
►Before connecng up your trailer for the rst me, check
that the height of the ball head on the car is in the range
of 395 - 465 mm between the road surface and the mid
dle of the ball head.
►Adjust the height of the ball head coupling on the car or
pad out the overrun device if the height dierence is too
great.
►If necessary, have a dierent ball head coupling aached
to your towing vehicle in a specialist workshop.
