5 General safety instructions
Observe the other general safety recommendations in
the operating instruction manual, “Trailers up to 3.5 to”
(General Points – Part 1).
WARNING
Driving with folded down/unsecured
drop sides/side wall extensions.
Folded down/unsecured drop sides and side wall extensions may
be torn off and flung away while driving – risk of impact/crushing!
Folded down drop sides cover the vehicle lights/vehicle
markings – increased accident risk!
►►Before driving off, check that all drop sides/side wall
extensions are closed and secured.
►►Remove all drop sides/side wall extensions/
stanchions when using the trailer as a flat-bed.
Loading/unloading bulk goods!
The bulk goods can press against the drop sides
during loading. Unsecured drop sides may spring
open, presenting a hitting/crushing risk!
►►Before loading bulk goods, make sure that all drop sides
are closed and secured.
►►Stand to one side when unlocking the drop sides – not
directly in front of it.
Materials on the trailer!
Materials such as snow/ice can be thrown on the road during
the journey – accident risk!
►►Remove ice and snow from the cargo bed/tarpaulin in
general and before driving off.
►►Check that there are no loose objects on the cargo bed/
tarpaulin before driving off.
Loose objects on the cargo bed
Climbing on the tarpaulin is absolutely prohibited!
The operator accepts full responsibility if this is disre-
garded.

10 Version 2019/01 Tandem HA, HN & HT Operating Instruction Manual (Part 2)
6 Loading and unloading
6.2.1 Loading/unloading the trailer
The trailer must be secured so it cannot roll away.
►►Make sure that road traffic safety is not impaired
when loading and unloading the trailer.
►►If necessary, use additional signalling devices, e.g., signs,
barriers.
6.1 Load distribution
Before loading, check the max. load capacity that you
are able to transport with your trailer.
Check that the max. permissible body dimensions of
your trailer are not exceeded.
The load distribution works directly on the road handling of the
towing vehicle tension.
NOTICE
Poor/one-sided load distribution of the goods!
Strongly uneven/point load distribution can lead to
overstressing and damage to the trailer components.
►►Before loading your trailer, check which
load objects are the heaviest.
►►Position the heaviest objects centrally on
the cargo bed and in the area of the axles.
►►Distribute the goods evenly over the cargo bed
- Avoid point/one-sided load distribution.
CAUTION
Folding ramp wall
After unlocking, the ramp wall can fall down
uncontrollably, e.g., from load pressure – impact
risk!
This can result in feet being crushed.
►►Stand to the side when unlocking the ramp wall.
►►Relieve the load pressure beforehand if necessary.
►►Allow the ramp wall to fall to the floor if the gas struts
are defective.
Never try to stop it.
►►Keep your feet away from the area around the
ramp wall.
►►Keep people away from the area around
the ramp wall during unfolding.
►►Use .
Walking on the mudguards is prohibited!
You can fall if you walk on the mudguards, since
the plastic mudguard gives way.
►►Do not climb on the mudguards.
►►If necessary, use a stable access aid, e.g., a ladder or stool.

Tandem HA, HN & HT Operating Instruction Manual (Part 2) Version 2019/01 11
Correct load distribution
kg
Load in axle area
The trailer and the towing vehicle are stable with all wheels on
the ground.
Incorrect load distribution
kg
Load too far forward (toward motor vehicle)
The trailer tilts forwards; the towing vehicle tilts backwards = the max.
drawbar load has been exceeded.
Incorrect load distribution
kg
Load too far backwards (from motor vehicle)
The trailer tilts backwards; the towing vehicle tilts forwards = the
drawbar load is too low or is negative.
6.2 Load securing
For relevant safety information for load securing, refer to
the section “General load securing” in the operating
instruction manual “Trailers up to 3.5 to – General part 1.”
WARNING
Unsecured load!
The load can be thrown around during the journey. The trailer
may start to lurch – accident risk!
►►Make sure that the load is secured by form and force-fit-
ting before driving off.
►►If required, have tie-down points retrofitted.
►► Ideally, secure the load with a combination of form-fitting
and force-fitting:
- Force-fitted by: Direct tie-down of the load.
- Form-fitted by: Supporting the various components
of the load against each other, against the drop sides
and against the cargo bed extensions, without spaces
in-between.
Tie-down options
The hook of the ties can be fastened to the tie-down bracket
from the inside or from the outside.
Loose load, not secured

6.2.1 Projecting load
In Germany, goods that project over the cargo bed or
drop sides must be marked in accordance with
Section 22 of the StVO (German Road Traffic Act).
> 1 m
Marking goods
1. Sign/flag (30 cm x 30 cm) or cylindrical body (ø 35 cm x 30 cm),
bright red
►►Check that your load does not exceed the maximum
permissible values according to Section 22,
“Goods,” of the StVO.
►►Mark any projecting goods.
- Make use of the prescribed means for doing so.
►►Do not load the goods too far forward.
- The required swerving range for driving around bends
must remain open!
WARNING
Restricted swerving range – risk of collision!
Supporting the load on the front drop side and allowing it to
project forwards reduces the swerving range when driving
around bends – accident risk!
►►Before driving off, check that the restricted swerving
range will allow your towing vehicle to drive around
bends.
►►Adjust the distribution of the load towards the centre
between the drawbar if necessary.
►►If necessary, remove the front drop side.
