Safety Instructions
The Swiss-Trac is a high-performance tractor for manual wheelchairs. Please comply
with the following instructions to guarantee operating safety:
Trailing Load and Gradability
Never overload your Swiss-Trac or use it for purposes other than those intended. The
maximum trailing load of 80 kg or 150 kg (see p. 24 "Technical Data") must not be ex-
ceeded under any circumstances. The maximum gradability of 20 % depends on the
ground surface. This value can decrease drastically with wet conditions or snow.
Cross Slope
Additionally, please follow the safety instructions in the instruction manual of your
wheelchair. The maximum permissible tilt in particular depends on the lateral stabil-
ity of your wheelchair, not on the Swiss-Trac.
Do not drive on a road or a path with a steep cross slope. There is a risk of tipping
sideways.
Bracket and Wheelchair
The bracket must only be used in its original condition and after having been cor-
rectly attached. To guarantee functional safety, please have the wheelchair’s bracket
checked annually together with the Swiss-Trac.
Driving and Steering
Avoid sudden acceleration or sharp steering motions.
Braking
Do not use the handbrake while driving. It only serves for parking. The Swiss-Trac
is equipped with a very efficient motor brake, with which the combination can be
slowed down reliably at any time.
Ledges and Obstacles
Kerbs and other obstacles always have to be driven over at right angles, never
sideways. Do not try to drive over ledges higher than 13 cm. This can damage the
wheelchair.
Parking
When parking the Swiss-Track, always remove the key and apply the handbrake.
Reflectors and Rear Lights
We recommend the installation of yellow reflectors on the spokes of the wheelchair
wheels and 2 red rear lights on the back of the wheelchair.
Never drive without a proper connection to the Swiss-Trac.

Road Safety and Liability
The Swiss-Trac is an auxiliary drive for wheelchairs and can be driven in pedestrian
areas at walking speed. Please follow the current traffic regulations. We recommend
taking out liability insurance.
Electromagnetic Fields
Radiation from electronic equipment, such as radio equipment, portable radios or
other powerful transmission devices, generates electromagnetic fields. This can in-
fluence the Swiss-Trac controls. If you notice unusual performance, stop and switch
off the Swiss-Trac. In certain cases, the Swiss-Trac itself can cause malfunctions of
electromagnetic fields. However, the use of wireless telephones and mobile phones
does not pose a problem.
Maintenance
Check the functionality of the gas stick at least once a week. Please do not drive if
the gas stick does not return exactly to neutral position due to the internal spring
resistance. Inform your specialist dealer and arrange for a repair.
Keep the Swiss-Trac and the wheelchair in dependable working order. In particular,
the brakes of the wheelchair must work flawlessly.
To guarantee functional safety, the Swiss-Trac and its bracket have to be main-
tained by an authorised specialist dealer once every year. The proof of mainte-
nance (see p. 29) has to be updated by the specialist dealer.

Checking the Bracket on the Wheelchair
The bracket, which is mounted to the wheelchair, is necessary to attach the Swiss-
Trac to the wheelchair.
Due to the many different types of wheelchairs, assembly and adjustment of the
bracket requires expertise and experience. Therefore, the assembly must be carried
out by an authorised specialist dealer. This also applies to a change of wheelchair or
after changes to the sitting position or inclination.
The bracket is properly adjusted when only minimum effort is needed for driving
and the front wheels of the wheelchair are lifted sufficiently when passing over
ledges.
During driving, hold the handlebars loose and between 10 and 15 cm above your
thighs. The front wheels of your wheelchair should always be 1.5 – 2 cm above the
ground.
If this is not the case, request an adjustment by your specialist dealer.
You can easily check the adjustment
yourself with a connected Swiss-Trac
during standstill, as shown here:

Ignition
Insert the key into the ignition switch on the control panel and turn it to the right.
After turning, the control light ignites and signals that Swiss-Trac is ready to be driven.
Do not operate the gas stick during startup / ignition. Otherwise, the procedure
described above has to be repeated after a short waiting time.
The control light also serves as an error display. In combination with an acoustic
signal, it indicates possible errors or improper operation (see p. 26 "Optical and
Acoustic Error Display").
Driving and Controlling Speed
The forward speed and backward speed can be controlled continuously with the
help of the gas stick. Move the gas stick slowly and constantly. To stop, move the gas
stick back into neutral position.
You can preselect the maximum speed using the fast / slow toggle switch: 4.5 km/h
on level 1 and 6 km/h on level 2.
The operating elements are arranged inversely on the special version with the "Gas stick on the right".
