The tightening torques stated in the following list are based
on the thread diameter for the nuts and bolts for which no
specific values have been determined. All values assume
dry and de-greased threads.
The batteries are discharged. Charge the batteries
as soon as possible.
The batteries are depleted. Charge batteries.
If you switch the scooter off for a few minutes, the
batteries can often recuperate to such a stage that a
short journey is still possible. You should only do this
in an emergency, however, because this causes the
batteries to become excessively discharged.
The battery voltage is too high. If the battery charger
is connected, disconnect it from the scooter.
The electronic system charges the batteries when
running downhill and when braking. This fault is
caused when the battery voltage becomes too high
during this process. Switch the scooter off and on
again.
The maximum current was exceeded over too long a
period, probably because the motor was overloaded
or has been working against an immovable resistance.
Switch the scooter off, wait a few minutes and then
switch on again.
The electronic system has determined a motor
short-circuit. Check the wiring harness for short-circuit
and check the motor.
Contact your Invacare provider.
Ensure that the disengaging lever is in the engaged
position.
There is a defect in the braking coil or in the cabling.
Check the magnetic brake and cabling for open
or short-circuited circuitry. Contact your Invacare
provider.
Drive lever is not in neutral when the keyswitch was
turned. Put the drive lever in neutral, turn the power
off and then turn on again.
It may be necessary to replace the drive lever.
Contact your Invacare provider.
The drive lever controls could be faulty or
incorrectly connected. Check the cabling for open
or short-circuited circuitry.
Potentiometer is not correctly adjusted and must be
replaced. Contact your Invacare provider.
The motor or its cabling is defective. Check the
cabling for open or short-circuited circuitry.
Contact your Invacare provider.
The scooter has exceeded the permissible maximum
speed during pushing or freewheeling. Switch the
electronics system off and on again.
