8.0 Maintenance and troubleshooting

The pulling device is equipped with an 8.5" or 14" drive
wheel.
With 14" drive wheels, make sure that the tyres are
always at the recommended tyre pressure, as this will
significantly affect the driving characteristics. If the tyre
pressure is too low, movement and manoeuvrability is
made more difficult due to the increased rolling resistance
and this also increases the amount of effort required.
The optimum tyre pressure (usually 3-4 bar) is indicated
on the tyre wall.

8.1. Fitting and repairing the tyre (14"):

NOTE:
The 8.5" wheel has a solid rubber tyre. Please contact
your dealer when tyres need to be changed.
• Switch the battery off and carefully remove it from the
pulling device.
• Unplug the cable which connects the drive wheel to the
pulling device at the connection. Make sure that no dirt
or moisture can get into the plug and clean the contacts
with a clean, dry cloth. Do not use lubricating or
penetrating oil to clean the contacts.
• Remove the drive wheel, by undoing the nuts which are
used to screw the drive wheel onto the fork on both
sides and then pull the drive wheel downwards off the
fork.
• Now pull the tyres off the rim using two plastic tyre
levers.
Before fitting a new inner tube:
• Inspect the base of the rim and the tyre inner wall for
foreign bodies and if necessary clean thoroughly
• Check the condition of the rim tape, particularly at the
valve hole. Only well fitting, strong rim tape offers long-
term protection against inner tube damage through
burrs and sharp spoke heads.
Fit by following the instructions in reverse order.
DANGER!
• Make sure you use the right torque for the wheel nuts
on the left and right of the fork (40 Nm).
• After fitting, check the tyre pressure again.

8.2. Regular maintenance

Your pulling device is subject to high levels of stress
when being used, and requires regular checks in order to
guarantee your safety.
DANGER!
Carry out the visual inspections/maintenance as
described below regularly, at least every 4 weeks, and
ideally before you set off each time:
• Make sure that all screws and fasteners are secure.
• Functional and safety check of all lights (if fitted).
• Functional/safety check of the docking system (pulling
device and wheelchair) to make sure they are secure
and check for wear.
• Check the brake pads for wear and that the brakes
work properly. The disk brake must be re-adjusted/
maintained regularly by a dealer.
• Check function of the disk brake (get your dealer to
replace cables and brake pads if needed).
• Visual inspection of the fork and intermediate sub-frame
for damage (e.g. cracks, corrosion, deformation etc.).
• Visual inspection of the wheelchair frame and back
tubes for damage (e.g. cracks, deformation, etc.)".
• Check tyres (tread, cracks, damages) and replace if
needed.
• Check the spoke tension and the rim and hub of all
wheels (wheelchair wheels as well) for damage.
• Check all cable and electrical connectors.
• Check that the steering head and handlebar are
secure.

8.3. Electrical system

If fault codes arise, or the electrical system of the pulling
device does not function as intended:
• Contact your dealer.
• Press the button on the charge status display in order
to wake the battery from "Deep sleep mode" if
necessary.
• Switch the pulling device on and push it forwards 1 m
by hand – check that it is working again
• Switch the battery off and carefully remove it from the
pulling device.
• Check all freely-accessible plug connections for dirt or
moisture. Clean the contacts if necessary with a clean,
dry cloth. Use contact spray if necessary, but do not
use lubricating or penetrating oil to clean the contacts
under any circumstances.
