6 Maintenance of the
wheelchair
The wheelchair’s lifespan is dependent on it
being well maintained.

fi c settings,
maintenance or repair work, please contact
your dealer. Always be sure to mention the
model, year of manufacture and identi
fi cation
number provided on the identi fi cation plate of
the wheelchair when contacting your dealer.
Note!
The wheelchair should be serviced by your
dealer once a year or, in the case of intensive
use, every six months.

6.2 Batteries
The wheelchair uses two 12V ‘dry’ gel batteries
in series. These batteries are fully sealed and
require no maintenance.
Note!
Do not use ‘wet’ batteries.
Take into account the fact that the wheelchair’s
range is reduced at low temperatures. During a
period of light frost, the capacity is roughly 75%
of the normal capacity. At temperatures below
-5˚C this will be roughly 50%.
Charging the batteries
(

Battery charger
)
Consult the user manual for the battery charger
to determine whether it is suitable for the
batteries in use. See chapter 8.
• Switch off the wheelchair’s controller.
• Plug the battery charger’s charging plug into
the charging connector on the controller.
• Activate the battery charger. Consult the
user manual for the battery charger.
Charge the batteries if the wheelchair is not
being used for an extended period of time. The
batteries should be charged every night under
normal use. The battery charger’s display will
indicate when the batteries are fully charged.
Depending on how depleted the batteries are,
it may take up to 12 hours to fully charge the
batteries again.
Maintaining the batteries
Note!
Ensure that the batteries are always fully
charged. Not using the batteries for an
extended period of time can damage them.
Do not use the wheelchair if the batteries are
almost depleted and never completely deplete
the batteries. This can seriously damage the
batteries and you may run the risk of coming to
an unintended standstill.
Replacing the batteries
If the capacity of the batteries is continually
decreasing so that the wheelchair can only be
used for short trips, then this means that the
batteries are reaching the end of their lifespan.
The batteries will then need to be replaced.
Please contact your dealer for assistance.
Warning!
Batteries contain acids. Damaged batteries are
a serious health hazard. Follow the instructions
on the batteries at all times.
