2.6.3 Travelling with the e-fix wheels in motorised operation
In motorised operation of the e-fix, its wheels must be engaged.
• Turn the coupling ring [5] anti-clockwise as far as it will go; the release catch [4]
must not under any circumstances be pressed in the process. A green marker is now
visible in the viewing window [3].
• Switch on the system (see chapter 5.2.1). The e-fix is now ready for motorised
operation.
When going downhill, power is fed back into the battery pack from
the drive wheels to increase the range. If you are travelling downhill
with a fully charged or almost fully charged battery pack and the
battery pack cannot take up any more power, this is indicated by a
warning in the control unit display (see table in chapter 6). If power
continues to be fed into the battery pack, the electronic system
automatically reduces the speed by 60 per cent.
If power consumption increases (if, for example you are travelling
on level ground or uphill), the e-fix can accelerate to the selected
maximum speed.
As soon as the charging process has finished, you can also accelerate
for a short time when driving on level ground.
The e-fix cannot be pushed manually in motorised operation.
The e-fix must only be used at temperatures between -25°C and
+50°C. Therefore, do not expose the e-fix to any heat sources (such
as intense sunlight) as this may cause surfaces to reach high tem-
peratures.
When not in use, do not expose your e-fix to strong sunlight for long
periods of time. This could cause the motor to heat up and in an
extreme case, not be able to operate at full power. Even plastic parts
age quicker under intense sunlight.
2.6.4 Range
All e-fix users are interested in the range of the system. In general, this is about 16 km
with a standard built-in battery pack (6 Ah), about 20 km for a battery pack of 7.5 Ah.
These are ideal values and relate to flat, paved terrain. Deviations may occur based on
topographical conditions, the ambient temperature, the surface being driven on, the tyre
pressure of the front wheels, the frame geometry, the weight of the wheelchair, the user
weight, and the type of drive wheels used.

For reasons of safety, the drive wheels must only be disengaged from motorised mode and set to push mode
while stationary and on a flat surface. The drive wheel must be load-free when being disengaged. To do so,
switch off the e-fix on the control unit. Actuating the clutch with a load or while travelling can damage the
internal mechanics and is thus not covered by the warranty or warranty service.
Disengaging on an incline can lead to a dangerous situation as the e-fix either switches either directly or sub-
sequently to neutral and thus, in the worst case, may start moving in an uncontrolled manner, i.e. may rotate
and/or roll downhill. Disengagement must only be performed on an incline in case of emergency and only if an
accompanying person is present to secure the wheelchair manually and using the wheelchair parking brake.
