3. Propel the Assist rim slowly forward. Drive
down the curb carefully and as slowly as
possible without changing direction.
Pushing the wheelchair to take an obstacle
An obstacle can be taken by an attendant
pushing the wheelchair. Put the power assist off
before pushing.
Driving on slopes
Warning!
When driving up or down a slope always use
an anti-tip device.
Only drive up/down a slope using the Assist
rims, since you have direct control for driving
and braking. Never use the Drive rims in this
case.
It is advised to use fully charged batteries
when driving up a slope (less charged
batteries can supply less power than fully
charged batteries). For taking slopes at least
2 LEDs of the battery indicator should be on.
Never use the Drive rims when driving up or
down a slope (only drive up/down a slope
using the Assist rims) and only in case you
would feel comfortable doing so (even) with a
manual wheelchair without Power assist.
Avoid sudden, jerky movements; always
drive carefully and with the highest
concentration.
Avoid making emergency stops on a slope.
For your safety: avoid changing direction on
a slope whenever possible.
Do not drive on slopes with loose gravel or a
sandy surface, as one of the driving wheels
could slip/spin.
If you notice a signifi cant decrease in speed
when driving up a slope, try to take a route
which is less steep.
Take special care when driving down slopes
of any kind. Adjust your speed to maintain
safe control.
When descending at a high speed, the power
assist can switch into the free running mode
due to over-voltage. The wheels continue to
run, but power assistance is not available
anymore.
Do not drive on slopes for extended periods
of time in order to prevent the motor from
overheating.
