4.8 Lifting the power assist
wheels
Caution!
In order to mount or lift the power assist
wheels, only hold them at the tyre or Assist
rim (fi gure 19). Never use the Drive rim,
the wheel handle or battery pack handle for
lifting the wheel (fi gure 20 and 21). This may
cause severe damage to the sensor system.
Warning!
If you do not feel secure lifting the power
assist wheel due to the weight of it, ask an
attendant to lift the wheel.

4.9 Safety functionalities

For your safety, several safety functionalities
are implemented in the system. Most of them
will not be noticed, but some can become
obvious in case of unintended use. These
intentional functionalities are described here.
1. When the wheel handle is in open position,
no support is possible. The system will
detect this situation and will switch off the
power.
2. A continuous Power assist request during
about ¾ wheel rotation will disable the
Power assist functionality (e.g. when the
Assist rim is blocked). Pushing one of the
profi le buttons will enable the function again.
3. Support is only available up to 6 km/h. If the
speed exceeds approximately 10 km/h, the
power assist will enable the 'braking on the
motor' feature to limit the speed increase;
In the most unlikely situation of generation
exceeding high voltage limits (>38V) the free
running mode will be activated.
4. If during the activation of the system the
Drive and/or Assist rim has a displacement
from the initial rest position, one or both of
the rims must be placed to the initial rest
position fi rst, before the function can be
used.
5. In case you are charging the main batteries
the motor is disabled.
