7. Driving

7.1 Driving with manual wheelchair wheels

In chapter 2 you learned how to mount the e-ﬁx wheels to and remove them from your

wheelchair. So you have the choice to use the conventional wheels that are manually

propelled or the electrically powered e-ﬁx wheels.

The parking brakes attached to your wheelchair [45] are adjusted to the e-ﬁx

wheels. When operating your wheelchair with the conventional wheels, the parking

brakes [45] may need readjusting!

7.2 Driving with e-ﬁx wheels in manual operation

The e-ﬁx wheels can be used manually like conventional wheels or in the power mode

(Change the mode only at a standstill).

· Switch off the e-ﬁx on the control unit.

· Turn the coupling ring [2] clockwise as far as it will go.

· If the release cover [1] protrudes beyond the coupling ring [2] and “

0“ is displayed

in the window [46], you are in “free wheeling“. The wheelchair can now be operated

manually.

· Should you unintentionally attempt to drive the e-ﬁx in this manual mode via the

control unit, a warning signal is emitted (if control unit is switched on). An error

message also appears on the display of the control unit (see Chapter 9.1).

Do not forget to apply the parking brakes [45] when the wheelchair is stationary.

These brakes that are attached to the wheelchair and adjusted to the e-ﬁx wheels,

prevent unintentional movement. Use of the e-ﬁx drive wheels in manual operati-

on in combination with a pulling device, for example in excess of 10 km/h, is not

permitted. For this purpose, use your manual wheels.

7.3 Driving with e-ﬁx wheels in electrically powered operation

For the electrically powered mode of the e-ﬁx, the wheels must be engaged accordingly.

· Turn the coupling ring [2] until it reaches the middle stop.

· “

1“ is then displayed in the window [46]. The release cover [1] is also ﬂush with

the coupling ring [2].

· Switch on the e-ﬁx at the control unit.

· The e-ﬁx cannot be pushed manually in the electrically powered mode.

When driving downhill, current is fed from the drive wheels back into the power

pack in order to increase range. If you drive downhill with a fully-charged or almost

fully-charged power pack and the power pack cannot accept anymore current, you

will be informed of this by a blinking power pack display and an acoustic warning

signal (5 short signal tones). If current continues to be fed into the power pack, the

electronics automatically reduce the speed by up to approx. 2 km/h. As soon as the

current consumption increases, in other words when travelling on a level surface or

uphill, the e-ﬁx accelerates until its previous speed is reached.

This behaviour may temporarily occur on level surfaces immediately after conclusion

of the charging process.”
