On a slope greater than 5°, take care to adopt a gentle drive, avoid jolts and braking suddenly and adjust the seat to be as stable
as possible. Do not attempt to do a U-turn on a lateral slope greater than 5°, as you could fall over sideways. If you cannot climb
a slope, try to reverse as perpendicular as possible up to it. Limit acceleration on slopes and favour an appropriate momentum.
If you have the steering lock option, it is advisable to use it to keep the wheels straight.
You will find details on joystick control in chapter 7.8.
7.2. «Crossing» driving profile
This procedure should only be used in case you have to cross over occasional obstacles of more than 4 cm high (sidewalks,
bumps, branches ...).
Warning
Take account of the recommendations of Part 2. Safety. Do not attempt to use the off-road or indoor driving profile with speeds of
greater than 3 km / h for obstacles greater than 4 cm.
The maximum speed limits permitted to cross over obstacles are:
• 1 to 2 km / h when the front wheels are in the climbing stage (risk of tipping back if going too fast)
• 2 to 4 km / h when the front wheels are in the climbing stage (if you do not go fast enough there is a risk that the rear
wheels won’t make it over the obstacle)
• 1 to 2 km / h when descending from obstacles (to have ease of use)
Be careful, occasional obstacles must only be crossed perpendicularly and in forward gear (avoiding the slopes). The seat incline
of the chair must be as parallel to the ground as possible and the incline of the backrest as perpendicular to the ground as
possible. The safety belt must be worn at all times. Make sure to respect the technical features of the chair (see corresponding
chapter).
The
PROFILE
button provides access to the driving profile «crossing». This driving profile is limited to 5 km / h when the
selected speed is at its maximum for the safety and comfort of the user.
If you have the «steering lock» option, it is advisable to engage the lock when the steering is straight. (See chapter 8.3 Steering
lock).
The crossing mode makes it possible to cross over obstacles of up to 15 cm in forward gear at low speeds, as it is programmed
to have instant maximum torque and power (strong acceleration).
The procedure for mounting a major obstacle such as a sidewalk is as follows:
• Align yourself as perpendicularly as possible to the obstacle.
• If you have the steering lock option, it is advisable to switch it on once the front wheels are aligned. To align the front wheels,
you will have to advance forward slightly.
• Approach the obstacle (20 cm minimum) and change the driving profile to «crossing» mode.
• Set the speed between to 3 and 5 in order to have enough speed to clear the obstacle (this may vary depending on the
wheelchair, the driving style and the weight of the user).
• Be careful as the incline of the seat must be as parallel to the ground as possible and the incline of the backrest must be as
perpendicular to the ground as possible. This will avoid any risk of tipping backwards when crossing the front wheels over
the obstacle.
• Advance at low speed to transition to the front wheels (between 1 and 2 km / h).
• When the obstacle is underneath the centre of the chair, use this momentum to accelerate and pass the rear wheels over it
(3km / h maximum). It is necessary to accelerate, as this gives the chair the power necessary to transition to the back wheels.
• When dismounting an obstacle, position yourself as perpendicularly as possible to it and descend slowly (1 to 2 km / h).
When you are in hilly or uneven areas with obstacles of more than 4 cm in height (dips, bumps, stones, branches ...), use the
driving profile «crossing» and do not exceed 3 km / h when passing over these obstacles. If you have the steering lock option,
it is advisable to use it.
