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.

14" and 8,5" wheel disassembly
• 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.
• Loosen the Allen screws
(A) on left and right side of
the wheel.
• Detach the safety locks
from the wheel nuts
• Remove the drive wheel,
by undoing the nuts which
are used to screw the
drive wheel onto the fork
