BATTERY STORAGE
If you no longer use your wheelchair, you can leave it connected to the battery charger. Charging is
automatically controlled by the battery charger. If you remove and store the batteries, kindly note the
following:
•
Remove the cable clamps from the poles of the battery.
•
The positive pole must be covered by at least one pole cap.
•
Only grasp the batteries by two opposite sides of the unit.
•
Make sure that no objects make contact with both poles during storage (danger of short circuits!).
•
Batteries should only be stored in dry, well-ventilated spaces at a temperature between 0°C and
+40°C.
•
Keep the batteries in the battery boxes for protection against damp or other external influences.
•
Protect the plugs and sockets of the battery boxes against corrosion.
•
Protect the batteries against drainage (see "Charging the batteries" section).
L
If batteries are not used, they can completely drain.
If you have further questions, consult your dealer who will gladly advise you on storing and
maintaining your batteries.
SYSTEM CONNECTION
THERMAL SAFETY MECHANISM
To protect the motor against overload, on the right side of the seat frame there is a thermal safety
mechanism (transition to the rear frame) that will automatically cut off the motor to prevent overheating
and thus rapid wear and tear or breakdowns. This can occur if you go up or down slopes that exceed
the maximum gradient indicated. Nominal loads exceeding the maximum could also trigger the safety
mechanism. If you try to drive with the brakes on, it could also result in overload. The values to comply
with are indicated in the “Technical Details” section. To be able to use the wheelchair again, remove
the overload and wait till the motor has cooled off, and then gently press in the thermal safety
mechanism again. The system is now ready for use again.
PARKING BRAKES
In addition to electromagnetic braking, your electric wheelchair could also be equipped with fixed
braking for each driving wheel. These must then be set for the wheels.
When pneumatic tyres are used, the parking brake can only function when the tyres are inflated hard
enough (see the section "Technical details").
L
Note that the tyre pressure should always correspond to the values given in the section "Technical
details", otherwise the action of the parking brakes would be reduced or even be zero.
