Driving on slopes
Warning!
When driving up or down a slope always use
an anti-tip device.
It is advised to use the Assist rims when
driving up/down a slope, since you have direct
control for driving and braking.
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.
Only drive on slopes where 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 significant 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.
The stopping distance on slopes can be
significantly greater than on level grounds.
When descending without using the rims,
the motor can start generating energy and
charging the battery when braking on the
motor is activated.
When descending with a too high speed, the
power assist can shut down automatically due
to over-voltage. The wheels continue to run,
but power assistance is not available anymore.
Driving up slope with Assist rim
1.
Propel the Assist rim slowly forward.
2. When releasing the Assist rim, the motor
brakes and prevents rolling back.
3.
The Assist rim can now be propelled forward
again.
4. Repeat steps 1-3 until the complete slope is
taken.
Warning!
When pushing back yourself e.g. from a table
the brake function as described above might
get active: To avoid this always push back
only with a very low speed.
Driving down slope with Assist rim
When driving down slope with the Assist rims
and you want to slow down, you can push back
the Assist rims softly. The motor will brake and
keep the speed constant.
Warning!
When the absolute speed limit is reached,
the user can notice a difference between both
wheels. This may cause the Power assist
diverge from its direction.
When driving down slope use both Assist rims
to correct the driving direction. Using only
one of the Assist rims might result in braking
on one side and cause an unexpected turn.
Driving down slope with Drive rim
Driving down slope with the Drive rim offers a
max speed of 6 km/h which can make it more
easy to drive a constant speed.
