Safety
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 exceeded 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 stability 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 correctly 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.
Never drive without a proper connection to the Swiss-Trac.
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.
Safety
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 influence 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 maintenance (see p. 29) has to be updated by the specialist dealer.

Overview
Checking the Bracket on the Wheelchair
The bracket, which is mounted to the wheelchair, is necessary to attach the SwissTrac 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.
Driving
Attach and Detach
Make sure to be on a flat surface during attaching and apply the brakes to your
wheelchair.
Attach
. Align your wheelchair as straight as possible behind the Swiss-Trac. Now lock the
wheelchair on both sides. Firstly, move the drawbar until its tip is at the height of
the seat cover. The drawbar should be located perpendicular to the bracket on
the wheelchair.
Should you be located too close to the tractor, move the Swiss-Trac forward
slightly in such a manner that you can barely reach it with both hands.
. Hold the handlebars with both hands and tilt the Swiss-Trac until the drawbar is at
the level of the bracket on the wheelchair and the control panel is just above your
knees.
. Now drive the Swiss-Trac backwards carefully and very slowly. During this process,
the drawbar has to slip into the bracket on the wheelchair. An audible click confirms a proper connection.
If the handlebars are held too high or the wheelchair is not aligned behind the
Swiss-Trac properly, your wheelchair might be pushed backwards by the SwissTrac. You can correct such misalignment by moving the handlebars slightly.
9
Detach
. Lock the wheelchair to detach. Keep the Swiss-Trac switched on.
. Turn the handlebars slightly to the left until you can reach the lever lug. Now
move the lever lug to the maximum.
. Drive the Swiss-Trac forward very slowly. The drawbar slips out of the bracket.
Release the gas stick as soon as the drawbar is free.
Do not push on the handlebars during detaching, as the drawbar will jam in the
bracket!
10
Driving
On-Road and O-Road Driving
Take your time for the first attempts at driving. Operate the gas stick carefully and
avoid driving around tight corners.
Before driving, check that the brakes are released on both the Swiss-Trac and
wheelchair.
Extensive driving instructions are provided by your specialist dealer.
The front wheels of your wheelchair should be raised about 2 cm when driving. To
achieve this, push the handlebar of the Swiss-Trac slightly forward when driving.
This ensures a more comfortable drive on uneven surfaces and trails.
To achieve ideal handling properties, the bracket has to be assembled on the wheel-
chair professionally (see p. 7 "Checking the Bracket on the Wheelchair").
With a driving assistance, the drawbar can be attached in such a manner that the
combination automatically remains in the ideal driving position (see p. 14 "Driving
Assistance").
Brakes
The Swiss-Trac is equipped with a motor brake, controlled by the motor-speed
control. This guarantees maximum driving safety.
Motor Brake
The motor brake is operated by means of the gas stick: When the gas stick is
moved into neutral position during driving, the motor brake engages automatically. When driving downhill, the motor brake limits the speed reliably at all
times.
To drive more slowly, switch the fast / slow toggle switch to level 1.
Gas Stick
Fast / Slow Toggle
Switch
Driving
Do not be startled if the Swiss-Trac rolls backwards slowly when you stop on a hill.
This is a controlled process which does not impose a risk. You can react to this by
slightly accelerating forwards.
If you intend to stop with the tractor for a longer period of time, you can utilize
the handbrake to secure the combination.
Handbrake (Parking Brake)
The handbrake may only be used for parking – with its help the Swiss-Trac can be
locked. Pull the handbrake and at the same time push the spring to the left with the
other hand. First release the handbrake, then the spring.
11
Spring for
Handbrake Handbrake
The handbrake must not be used while driving. The risk of skidding is very
high, especially on steep ground!
Turns and Turning Radius
Reduce the speed in tight curves if necessary. Disable the driving assistance during
manoeuvring.
Please consider that the turning radius can be more than 1.5 m depending on
the wheelchair. In narrow aisles or in front of an elevator, it could prove difficult
to turn the combination. In such cases, we recommend detaching the tractor,
turning the Swiss-Trac and the wheelchair separately and reattaching them again
afterwards.
12
Driving
Passing Ledges and Obstacles
Passing over ledges requires a bit of practice. You will soon be able to carry out this
process with ease.
The driving assistance must always be released before passing over obstacles
to avoid damaging the front wheels of the wheelchair.
Upwards
.
Approach the ledge slowly and as
perpendicular as possible. Start to lift
the handle slightly, so that the front
wheels of the Swiss-Trac are raised a
little above the ground.
.
As soon as the front wheels of the
Swiss-Trac touch the ledge, push the
handlebars hard forwards with both
hands and accelerate briefly. Like this,
the front wheels have enough strength
to pull you over the ledge.
If the rear wheels spin, you might
have pushed the handlebar forwards
too late.
.
Hold the handlebars in a forward
position during the entire process. The
front wheels of the wheelchair should
be raised enough so that they do not
bump against the ledge.
It is advantageous to shift your
upper body forwards at the moment
you pass over the ledge.
Driving
Downwards
.
Approach the ledge slowly and at a
right angle until the front wheels
of the Swiss-Trac reach over the edge.
Then push the handlebar hard forwards until the front wheels touch the
ground below.
The front wheels of the Swiss-Trac
must touch the ground below before the rear wheels. Otherwise, the
bracket or the wheelchair could be
damaged.
.
Hold the handlebars pushed forward
until the entire combination has
passed the edge. Afterwards, lower
the handlebars to the normal driving
position.
13
Maximum height of obstacles: 13 cm upwards, 15 cm downwards.
Do not try to drive over stairs with several steps!

Driving
Driving Assistance
The driving assistance takes strain off the shoulders and arms by stabilizing the
combination in the ideal driving position when enabled. At the same time, the effort
required while driving decreases markedly. It is an addition to the drawbar which,
when engaged, constantly holds the front wheels of the wheelchair in an elevated
position.
For persons with limited functionality of the upper extremities and less strength in
arms and hands, this makes driving longer distances with the Swiss-Trac possible.
Drawbar without
Driving Assistance
Wheelchair and SwissTrac are movable via
the drawbar. The driver
balances the combination
actively.
Drawbar with Driving
Assistance
When the driving
assistance is engaged,
the wheelchair and SwissTrac remain in the driving
position automatically,
the wheelchair front
wheels are raised about
2 cm.
Depending on the degree of disability, type of wheelchair and individual needs,
different types of driving assistances and drawbars are utilized. Let your specialist dealer advise you.
Batteries
Batteries
The AGM lead-acid batteries (dry-cell batteries) used for the Swiss-Tracs are of high
quality. They are leakproof and meet the current requirements for safety and environmental compatibility. They also meet the current IATA / ICAO special provision A67
requirements and are approved for air transport.
For air travel, you can find a confirmation of the compliance with all safety stand-
ards on our website www.swisstrac.ch (see also p. 20 "On Planes").
Avoid discharging the batteries completely (i.e. Avoid driving until the Swiss-
Trac stops operating). Complete discharge of the batteries reduces the battery
capacity and decreases the battery life drastically.
The replacement of batteries has to be carried out by the specialist dealer. The
factory-set charging characteristics of the charger match the installed batteries
and are not to be altered. The wrong charger may damage the batteries and the
charging socket.
Battery Display
The battery display on the control panel displays the charge level of the batteries:
15
Full
The charge level is displayed as a red bar when
the batteries are fully
charged.
Almost Empty
The display will start
flashing in red when the
batteries have discharged
by about 75 % of their
capacity. In this case, only
drive in level 1.
Empty
When the last 2 bars start
flashing alternately, the
batteries are empty and
urgently need to be recharged. If you continued
to drive at this point, the
batteries’ life would be
decreased.
16
Range
The range of the Swiss-Trac with fully charged batteries depends on several factors,
such as weight, tyre equipment, gradient and the batteries’ capacity.
On flat routes with an average speed of 5 km/h, a distance of about 30 km or more
can be driven.
Ascents with high gradients reduce the range significantly. During descent, the
batteries are partially recharged again.
Charging the Batteries
The Swiss-Trac is equipped with maintenance-free AGM lead-acid batteries and an
external charger. Extensive information on the charger can be found in the corresponding instruction manual.
Batteries
The charging socket for charging the batteries is located beneath a black hinged
lid. Plug the round charging plug of the charger into the charging socket and the
power plug into the power supply.
Charging the batteries completely takes at least 8 hours. Overcharging is not possible.
The charger operates with a voltage of 100 – 240 volts and can be used worldwide
with a corresponding travel adaptor.
In general, the batteries should be charged after every long drive. Only charge the
batteries in dry, well ventilated rooms at a temperature of +10 °C to +45 °C.
Use only the original charger. Other chargers can cause a short circuit in the
charging socket and the charging plug, and damage the batteries.
Batteries
Maintenance when Not in Use
When the Swiss-Trac is not in use, it is recommended to charge the batteries every
4 to 5 weeks.
If lead-acid batteries are not used over several months, the battery capacity decreases due to self-discharge. To avoid this, charge the batteries completely prior to
storage and proceed as follows to remove the main fuse:
17
. Fold up the clasp on the upper
end of the bonnet.
. Open the bonnet by pulling on
the luggage carrier.
. The main fuse (40 amps) is orange
and is located on the side, next to
the batteries. Pull the main fuse out
vertically upwards.
The batteries are damaged if the main fuse is not removed for longer storage
periods.
Disposal
The battery life is about 2 years. However, it also depends on usage and charging
cycles. At the end of this battery life, the batteries are disposed of by your SwissTrac specialist dealer according to environmental regulations.
18
Transport
Transport
The Swiss-Trac can be loaded into a standard estate car independently by the
wheelchair user. The Swiss-Trac can be transported on wheelchair accessible public
transport. Transport on planes is also possible.
In the Car
Loading ramps are provided for loading the Swiss-Trac into a car. These can be
used with every vehicle with a loading sill up to a height of 55 cm off the ground.
For cars with a higher loading sill, longer, foldable loading ramps are available
(see p. 25 "Accessories").
Loading
. Place the loading ramps on the loading sill and insert the spacer bar between the
loading ramps.
. Drive the Swiss-Trac backwards onto the loading ramps on speed level 1 until all 4
wheels are located on the ramps.
.
Loosen the lever screw of the steering handle while the Swiss-Trac is slightly rolling
downwards again (see p. 6). The handlebars should remain raised for the moment.
. Drive with the wheelchair diagonally to the left, next to the ramps, in such a way
that you can still reach the gas stick with your right hand. Reverse the Swiss-Trac
slowly and press on the control panel with your hand.
As soon as the Swiss-Trac is moving out of reach, swing the steering handle down
to the side and release the gas stick.
. The Swiss-Trac should be completely inside the car by now. Switch it off and ap-
ply the handbrake (see p. 11 "Brakes"). Finally, place the loading ramps in the car.
The Swiss-Trac should be secured during transport in the car. If your car is
equipped with restraining belts, e.g. in the corners of the boot, span them
tightly around the bumper of the Swiss-Trac.
Transport
Unloading
. Place the loading ramps on the loading sill and insert the spacer bar between the
loading ramps.
. Drive the Swiss-Trac very slowly onto the loading ramps.
. Without accelerating, let the Swiss-Trac roll downwards. In order to avoid tilting
of the Swiss-Trac, push downwards lightly on the steering handle above the drive
wheels.
. When the Swiss-Trac comes to a halt on the bottom of the loading ramps, swing
the steering handle upwards and tighten the lever on the steering handle.
Do not park the car with a loaded tractor in the sun! Extreme heat can damage
the Swiss-Trac!

20
In Public Transport
The Swiss-Trac can be transported in wheelchair accessible public transport, such
as a train, bus, tram, cable cars and passenger ships.
Where possible, stay connected to the tractor in buses and trams. That way, the
entire combination is more stable during bumpy drives.
In case of doubt, clarify the precise procedure with the transport service.
On Planes
As a rule, all big airlines transport the Swiss-Trac free of charge as an accessory of the
wheelchair. On our website you can find a leaflet with travel information and a confirmation that the utilized batteries meet the current requirements of the "ICAO Special
Provision A67":
The Swiss-Trac weigh 65 kg (SWT-1) and 55 kg (SWT-2), respectively.
Normally, you will be able to drive the Swiss-Trac up to the check-in or the bulky
lugagge counters and then make it ready for transport.
. Remove the key and the main fuse (see p. 17 "Maintenance when Not in Use"),
then fold the steering handle downwards.
. The lever screw for locking the steering handle must be tightened again.
. Apply the handbrake and secure the drawbar with a strap or string on the side of
the luggage carrier.
. The key, main fuse and bracket are best transported in the hand luggage and not
the suitcase.
www.swisstrac.ch
Transport
Do not transport the tractor on a belt. Attach the transport banner, which is
available as an accessory, to the Swiss-Trac before the flight (see p. 25 "Accessories").
Maintenance
21
Maintenance and Cleaning
Keep the Swiss-Trac and the wheelchair safe to operate. To guarantee your safety,
the Swiss-Trac and its accessories have to be periodically inspected and maintained. The inspection and maintenance has to be carried out by an authorised
specialist dealer at least once a year. Please contact your specialist dealer for this
(see p. 29 "Proof of Maintenance").
Gas Stick and Brakes
Check every week if the gas stick and the handbrake are functioning properly.
Please do not drive if the gas stick does not return to the neutral position au-
tomatically due to the internal spring resistance. Arrange for a repair by your
specialist dealer.
Bracket on the Wheelchair
The wheelchair and its bracket have to be included in the maintenance. Check the
mount and the proper functionality of the bracket (audible clicking when attaching) periodically.
Tyres and Air Pressure
Check the air pressure of the tyres every 2 months (see p. 22 "Air Pressure of the
Tyres"). Also check the tyre equipment of the wheelchair, its air pressure and the functionality of both wheelchair brakes.
The wheels can be cleaned with the help of a water hose. Make sure that the
bonnet and the charging socket’s lid are closed during the process.
Control Panel and Bonnet
The control panel and the bonnet are best cleaned with a damp cloth.
Do not spray the control panel with the water hose during cleaning! Do not use
high-pressure cleaners or aggressive cleaning agents to clean the tractor.
22 Maintenance
Tyre Equipment
All wheels of the Swiss-Trac are fitted with pneumatic tyres. Note that not all tyres
require the same air pressure.
Air Pressure of the Tyres Rear wheel Front wheel
Block Profile Tyres (standard) 2.0 bars 2.5 bars
Cross Profile, Tractor & Studded Tyres 1.5 bars —
See p. 25 "Accessories" for cross profile, tractor and studded tyres.
To increase driving comfort and ground contact, the air pressure of the tyres can
be lowered for trails.
Insufficient air pressure can damage the tyres. Therefore, please check the air
pressure at least every 2 months. All inner tubes are equipped with American valves
(Schrader valves). They can be pumped up at all petrol stations. To fill the front
wheels with air, the Swiss-Trac has to be tilted backwards onto the drawbar, then,
rotate the tyre until the tyre valve on the inside of the rim can be reached.
Wheel Repair
The large rear wheels can be removed entirely from the tractor when repairs are
necessary.
For a wheel repair, the following repair tools are required:
• Socket Spanner 10 mm with cross-handle and extension
• Hexagonal pin spanner / Allen wrench SW 4 mm (for the front wheels)
• Tyre pump for American valves
• Tyre repair kit (available at bicycle shops)
Rear Wheel (Drive Wheel)
. Deflate the tyre entirely by means of the valve.
. Loosen the 3 wheel nuts on the rim and remove the wheel.
. Loosen the remaining 3 nuts on the inside of the wheel.
. Take apart the two-part rim. The inner tube can be repaired with the help of the
tyre repair kit or by replacing it entirely.
. Put the inner tube into the tyre and fill it slightly before further assembly.
Make sure that the valve is not placed above a wheel nut.
. Assemble the wheel and attach it to the Swiss-Trac. Only now should the tyre be
fully inflated.
Maintenance
Front Wheel
In case of a flat tyre on the front wheel, it is not necessary to completely remove the
wheel to repair it. The rims also consist of 2 parts and the 5 screws on the inside of
the rim can be loosened. The repair process for the front wheel corresponds to the
repair process for the rear wheel.
Please contact your specialist dealer in case of any problems and for any spare
parts you may need to order.
23
Headlight
You can easily replace a defective headlight bulb by yourself:
. Switch off the Swiss-Trac.
. Open the bonnet (see p. 17).
. Turn the contact strip that pushes down the bulb in the middle to the side.
. Remove the bulb by turning it slightly.
. Put in the new bulb and finally turn back the contact strip.
Reuse and Disposal
The Swiss-Trac is a high-quality and durable product and therefore generally suitable for reuse. The requirement for this is the observation of the operating requirements and of the service and maintenance requirements.
The bracket of the wheelchair or its parts must never be reused.
Before reusing a Swiss-Trac it has to be inspected for functionality, condition and
wear by an authorised specialist dealer.
Used parts must not be used in a new Swiss-Trac.
According to the modern state of the art, the Swiss-Trac has a service life of between
5 and 10 years. At the end of this period, it can be returned to your Swiss-Trac specialist dealer for professional recycling.
