driving. Observe the following safety instructions when
driving the power wheelchair:
n Do not drive on inclines and slopes of more than 12 %.
n When driving downhill, reduce speed in accordance
with the degree of the incline.
n Do not cross obstacles with differences in height of
more than 5 cm.
n Do not cross steps or curbs without braking rst.
The power wheelchair has been approved for driving on in-
clines and slopes of no more than 12 %. You are not al-
lowed to drive on inclines or slopes steeper than this.
To ensure safe downhill driving, the driving speed must be
reduced in accordance with the degree of incline (e.g. set it
to speed level 1).
The critical obstacle height of the power wheelchair is 5 cm.
It is not permitted to cross obstacles higher than 5 cm. Ob-
stacles such as steps or curbs must be crossed at reduced
speeds.
If there are obstacles in the travel path, it is important to
drive around them with a large margin of safety. On uneven
ground, the driving behaviour of the wheelchair may get out
of control. Therefore the speed must always be adapted to
the ground conditions.
The joystick (see g. 14, item1) is used for driving. The fur-
ther the joystick is moved away from the mid-position, the
faster the power wheelchair will drive in this direction.
The maximum speed with full deection of the joystick de-
pends on the selected speed level. Releasing the joystick
automatically activates the brake function, which brings the
wheelchair to a halt. When standing still, the mechanical
brakes are automatically active so the power wheelchair
cannot move.
The power wheelchair has ve speed levels. The speed but-
tons (see g. 14, Items 2/3) are used to increase or de-
crease the speed level. The current speed level is indicated
by lighting the “Speed Level” LED. The signal tone will
change when the highest/lowest speed level was achieved.
