controls again, the brakes must be released to switch
over to the pushing mode. In this case, contact a
specialist dealer as soon as possible.
r
If the controls do not emit an error signal as soon as
the brake lever is activated, something has malfunc-
tioned. The settings must be checked by a specialist
dealer.
r
The power wheelchair can be used for transportation
of the person in vehicles for the disabled, with some
restrictions. Please read the information contained in
section 5 (Storage/Transport).
r
Explosive gases can develop while the batteries are
charging. For this reason, the following precautions
are to be taken during charging:
– The controls must be turned off.
– Provide for sufficient ventilation when using the
battery charger in closed rooms.
– Smoking and fire are not permitted. Sparks must
be avoided.
– The vent slots of the housing must not be covered.
r
For power wheelchairs featuring a battery drawer:
When closing the battery drawer, the release bolt must
engage in the recess provided for this purpose. The
release bolt must be easy to see and touch on the
underside of the drive unit sustainer.
r
In case of power wheelchairs which feature gas com-
pression springs, attention must be paid to oil leaking
from the piston rod. Leakages reduce the functional
capabilities of the gas compression springs and result
in their failure.
r
Defective gas compression springs (e. g. scratches
or damage to the piston rod caused by impact; defor-
mation of the cylinder tube) must be replaced imme-
diately. Piston rods do not need lubrication. They are
maintenance-free.
r
When the wheelchair is not used for extended periods
of time, or if the tyres are heated strongly (e. g. near
radiators or by sunlight shining through a window),
permanent deformation of the tyres will result. There-
fore always make sure that the wheelchair has suffi-
cient distance from sources of heat, move your wheel-
chair from time to time, or jack up the wheelchair when
storing it.
