The “Crossing” profile allows you to surmount obstacles of up to 15 cm in length, moving
forward at low speeds, because it is programmed for torque and instantaneous power
(powerful acceleration).
• It is recommended to use the “Steering lock” function when driving straight forward.
(See chapter 8.3. Steering lock).
The maximum speed limits authorized for surmounting obstacles are:
• 1 to 2 km / h while the front wheels climb the object (risk of tipping backwards if the
speed is excessive)
• 2 to 4 km / h while the rear wheels climb the obstacle (lack of speed here risks not
surmounting the obstacle)
• 1 to 2 km / h during the descent of obstacles (risk of tipping forward)
The procedure for climbing an occasional obstacle such as a footpath is as follows:
• Position yourself perpendicularly in front of the obstacle.
• Drive forward slightly in a straight line straight line in order to align the wheels with
the obstacle.
• It is recommended to engage the steering-lock while surmounting an obstacle in order
to maintain the straightness of the wheels.
• Approach the obstacle (20 cm minimum) and select the ‘’ crossing’’ driving profile.
• Set the speed between 3 and 5 in order to have enough speed (this may vary
depending on the chair, driving style and weight of the user).
• Adjust the chair with the seat parallel to the ground and the the backrest to a
perpendicular position in order to avoid any risk of tipping backwards while the front
wheels climb the obstacle.
• Advance at a reduced speed ( 1 or 2 km/h ) for the front wheels to mount.
• In this momentum, when the obstacle is in the middle of the wheelchair, accelerate ( 3
km/h maximum) to pass the rear wheels. It is necessary to accelerate, in order to have
sufficient power to pass the rear wheels.
• When descending an obstacle, position the wheelchair perpendicularly and descend
slowly (1 to 2 km / h) forwards.
7.3. STEERING LOCK
The steering lock allows you to lock the right wheels for easier maneuvers in reverse, when
surmounting an obstacle, getting the wheelchair into a vehicle or when the ground is slippery...
To lock the steering, first put the front wheels as straight as possible and pull the lever upwards.
To unlock the steering, push the lever downwards and shift it to the side to prevent it from
moving. (Fig. 4)
