Obstacles & Kerbs - Sunrise Medical Quickie Q500 M Manuel D'utilisation

5.7 Obstacles & kerbs:
DANGER!
• Never descend a kerb backwards.
• Do not attempt to climb or descend a series of steps or use
on escalators. It is unsafe to do so and could cause personal
injury or damage the chair. This wheelchair has only been
designed to climb a single step or kerb.
• We recommend that users with upper trunk instability wear
restraint systems to keep the upright body position during
descending or ascending ramps, kerbs or obstacles.
Kerb climbing:
Always approach a kerb at 90° (Fig. 5.2).
• Approach the kerb or step, head on at a 90° angle.
• Drive forwards slowly and steadily.
• Stop the chair as soon as the castor wheels touch the kerb.
• Apply sufficient power to the motors to lift the front of
the chair up onto the kerb or step and then apply slightly
more power until the drive wheels climb the kerb or step
smoothly.
• As far as possible, keep the joystick in the straight forward
position.

Dismounting the kerb.
DANGER!
Move the chair slowly and carefully in a forward direction until
both front wheels are on the edge of the kerb, again in a 90°
position to the kerb.
Drive as slowly as possible off the kerb with the drive wheels.
Don't stop the chair during descent of the kerb. You will feel
more secure if you can lean backwards, but if you can't, don't
worry, the wheelchair is stable. As long as you stay within its
limitation, you will be quite safe.
All powered seating options need to be in home position. Your
powered leg rests may need to be adjusted to give enough
clearance to mount or dismount the kerb.
We recommend to use the lap strap to feel more secure during
declining the kerb. For extra protection we recommend to fit
every chair with the leg rests.
WARNING!
In a RWD chair it may be preferrable to dismount the kerb in
the reverse direction. Though it is advised to do so slowly and
to be aware of traffic and your surrounding environment. It
is also recommended to have assistance whilst undertaking
this procedure. Only kerbs less than the recommended 80mm
should be dismounted.
