1.6 Safety instructions
L When getting into and out of the wheelchair, do not stand on the footrests. The footplate
should be folded up beforehand.
L Investigate the effects of shifting the centre of gravity on the behavior of the wheelchair,
for example on up or down gradients, on laterally sloping ground, or when overcoming
obstacles. Obtain support from an attendant.
L If you want to pick up something (lying in front of, on the side, or to the rear of the
wheelchair), you should not lean too far out to avoid tipping over.
L When moving through doors, arches, etc. ensure that there is enough room at the sides
so that you do not get your hands or arms caught or crushed and that there is no
damage to the wheelchair.

L WARNING: Risk of injury - Check that all plugs (battery charger and
programming unit) are removed before setting the wheelchair in motion.
The socket for connecting the charger supplied is located on the
front of the operator control. Here, too, is the connnection for the
programming unit, which should only be connected and used by
authorised persons who have been trained to program it (Vermeiren
personnel).
2.15.5 Your first trip
L
LL
L WARNING: Control your electric wheelchair - Accustom yourself with the driving
behavior of your electric wheelchair.
•Driving
Once you are seated on your electric wheelchair and have started it as described above,
take the joystick with your hand and push this in the required direction i.e.:
PUSH ACTION FORWARD = FORWARD MOVEMENT
PUSH ACTION BACKWARD = BACKWARD MOVEMENT
•Braking
To brake, let go of the joystick, which will let it return to the zero position and slow down your
electric wheelchair to a gentle stop. Practice pulling away and braking to get accustomed to
the electric wheelchair. You need to be able to estimate how your electric wheelchair will
react when you drive or brake.
•Driving in corners and bends
L
LL
L WARNING: Risk of tipping over - Reduce your speed before you enter a curve or
corner.
L
LL
L WARNING: Risk of clamping - Always maintain an adequate distance from
corners and obstacles.
L
LL
L WARNING: Risk of injury - Be careful with the front wheel drive wheelchair, the
rear of the wheelchair can swing while turning.
Move the joystick into the position you wish to turn. The back wheels will turn accordingly
and steer the electric wheelchair into a new direction. It is very important that you ensure that
there is enough space allowing you to go around bends and corners. Narrow passages must
preferably be approached in a large curve so as to allow you to enter the narrowest part as
straight from the front as possible.

Take care not to enter curves and corners diagonally. By ‘cutting the corner’, chances are
that your rear wheels, back of wheelchair will run into obstacles and destabilize your electric
wheelchair.
2.15.6 Backward movement
L
LL
L WARNING: Control your electric wheelchair - Accustom yourself with the driving
behavior of your electric wheelchair.
L
LL
L WARNING: Control your speed - Always go backward in the lowest speed
possible.
L
LL
L WARNING: Risk of collision - Always look to the back when you go backward.
Rearward driving requires increased concentration and care. This explains why we have
greatly reduced the speed of rearward movement in comparison with forward driving. But we
still recommend that you put the speed on minimum when you drive backward.
Left and right controls act inverse when driving backwards.
2.15.7 Going uphill
L

L WARNING: Control your electric wheelchair - Accustom yourself with the driving
behavior of your electric wheelchair.
L
LL
L WARNING: Control your electric wheelchair - Never put your electric wheelchair
in freewheel on slopes.
L
LL
L WARNING: Control your speed - Move on slopes as slow as possible.
L
LL
L WARNING: Risk of tipping over - Do not exceed the maximum gradient of static
and dynamic stability uphill (see paragraph "Technical specifications")
L
LL
L WARNING: Never reverse going uphill.
Always approach slopes directly from the front and, to avoid tipping over, see that all four
wheels stay in contact with the ground at all times (ramps, driveways, etc.).
If you come to a stop on a slope by letting go of the joystick, the engine break will prevent
your electric wheelchair from rolling backward. As soon as the joystick returns to zero
position, the engine break is activated.
To resume your uphill drive, push the joystick as much as possible to the front to ensure the
release of a sufficient amount of power. This will allow your electric wheelchair to slowly
ascend the slope.
If your wheelchair is unable to drive up, turn the speed control up and try again.
