3 Intended Use
• Transporting of goods, with the exception of
hazardous goods, e.g. explosive, chemical or liquid
materials.
• Transporting of small garden vehicles, motorcycles,
bicycles, with corresponding fitted accessories and a
suitable trailer type with loading aids.
• Transporting of fixed / loose loads.
4 Foreseeable misuse
• Transporting of persons or animals.
• Driving over the ramp wall with an excessive load or
a high point load.
• Tipping of goods into areas where there are persons
or objects.
• Tipping the cargo bed while persons are on it.
• Driving with the wood/aluminium cover / loading
ramps / cargo bed / drop sides unlocked.
• Driving with side wall extensions / H-frame not
bolted to stanchions.
• For "Steely" type: Driving with goods projecting over
the back of the vehicle.
• Driving with insufficient load securing.
• Non-observance of the safety instructions in the
operating instruction manual, "Car Trailers" (Part 1).
5 General Safety Instructions
Opening the ramp wall!
An unlocked ramp wall may fold down and hit /
bump you!
►►Stand to one side when unlocking the
ramp wall - not directly behind it.
Unsecured tilting cargo bed!
In tilting trailers, the cargo bed may tilt on its own
while driving.
►►Before driving off, check that the cargo bed is
secured with the eccentric tension locks.
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 mark-
ings - increased accident risk!
►► Before driving off, check that all drop sides / side wall
extensions are closed and secured.
►► Before driving off, check that the side wall extensions are
bolted to the stanchions.
Single-axle trailer snaps open!
Single-axle trailers can snap open during loading /
unloading and parking, and crush fingers / hands /
feet or collide with you.
►► Only park the empty trailer on the jockey wheel or the
drawbar support.
►►Only couple/uncouple the trailer when it is empty.
►►Make use of the prop stands during loading / unloading
or couple the trailer to the towing vehicle.
Observe the other general safety recommenda-
tions in the operating instruction manual, "Car
Trailers" (General Points - Part 1).
WARNING
CAUTION

OI (Part 2): Steely, HA, Startrailer Version 2019/01 13
6 Loading and Unloading
Single-axle trailers may only be loaded and
unloaded with goods after being coupled to the
towing vehicle.
6.1 Load distribution
CAUTION
Negative / insufficient drawbar load!
Maximum permissible drawbar load exceeded!
A negative / too-low drawbar load or exceeding the maximum
permissible drawbar load may result in accidents.
►►Distribute the weight evenly across the trailer.
►►Do not fall below the minimum drawbar load of the
trailer (for trailers up to 750 kg gross weight, this is:
4% of the towed load or 25 kg).
►► Do not exceed the maximum permissible drawbar load
of the towing vehicle and trailer coupling.
►►Where possible, make use of the maximum permissible
drawbar load (see COC papers, Section 19).
►► Observe the information on the maximum
permissible drawbar load in your vehicle papers
and the trailer coupling.
►►Do not exceed the maximum permissible drawbar load
of the trailer. Observe the information on the maximum
permissible drawbar load in the COC papers, Section 19.
Avoid turning your load into a projectile.
• The static force [m] is used as a point of departure
for dimensioning the means of load securing.
• As the speed increases, so does the inertia /
centrifugal force of the load.
• Sample calculation:
[m] = 1 kg ~ 1 daN static force
[v] = acceleration speed of mass
[Ekin] Formula: Ekin= m • v2

at 0 kph = 1 kg kinetic energy

Forces acting on trailer when fully braked
Conclusion:
• When doubling the speed, the kinetic energy that
can be released by the unsecured load when the
trailer is fully braked increases four-fold.
• Wrongly / poorly distributing the load results in
serious accidents, even at low speeds.
• Overloading the trailer means intentionally producing a
risk, which can result in the trailer skidding and meeting
with a serious accident even after a minor steering
manoeuvre, a bump in the road or a gust of wind!

e.g. 500 kg must be secured with 250 daN

14 Version 2019/01 OI (Part 2): Steely, HA, Startrailer
►►Counteract the potential release of forces by:
• Correct load distribution
• Using adequate means to secure the load in
accordance with its weight (tie-down equipment,
tie-down points)
• Using anti-skid materials (anti-slip mats)
• Correctly attaching the load, e.g. with a cover net,
tarpaulin or cover
• Adapted speed
• Additional accessories (H-frame, side wall extensions)

►►Preferably secure the load as 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-be-
tween.
6.2.1 Projecting goods
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).
For the "Steely", the goods generally must not
project beyond the back of the trailer!
> 1 m
1
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!
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!
►►Remove the front and rear drop side.
►►Before driving off, check that the restricted
swerving range will allow you towing vehicle to
drive around bends.
►►Adjust the distribution of the load (towards the
middle of the drawbar) if necessary.
