Push Mode on Stairs
If the wheelchair stops in the middle of stair, it is possible to evacuate the user to the next landing in a controlled manner.
Risk of pinching due to rotating main wheels
The wheelchair’s main wheels turn during the evacuation. Beware of the danger of getting fingers and hands caught.
Do not get out of the wheelchair on the stairs
If possible, please have yourself lowered to the next accessible landing or flat platform before getting out of the wheelchair. The device may be unstable on the stairs and getting out of it may be dangerous because of its high elevation.
Downward evacuation from a stair (recommended)
Power the wheelchair off using the main switch at the back (see Figure 4, “Labelling of main switch and brake release”).
Ask pedestrians who may be below the wheelchair to move away from it. They could be injured.
Ask an assistant to press the “Brake Release” button at the back (see Figure 4, “Labelling of main switch and brake release” very briefly (about half a second) before releasing it again. → This releases the brakes briefly and the wheelchair begins to slowly descend on its tracks.
Ask the person assisting you to keep pressing the button repeatedly to enable you to descend slowly until you reach the landing below you. The button must be released immediately if the wheelchair moves too quickly.
If necessary, the wheelchair’s alignment on the stairs can be altered by braking the left or right wheel (press against the tyre with your hand). The wheelchair can be moved completely onto the next landing by rotating the main wheels forwards. The main wheels act as a transmission so that no great force is necessary.
Upward evacuation from a stair
Danger at the top of the stairs
When arriving at the top of the stairs, the wheelchair must be tilted backwards over the edge and supported by your assistants. Otherwise the wheelchair could tip over. For this reason, Scewo always recommends that the evacuation is carried out by going down the stairs where possible.
If necessary and provided that at least three people can provide assistance, the wheelchair can also be moved up the stairs on its main wheels. The main wheels act as a transmission so that no great force is necessary:
Assistant 1 and 2 should stand to the left and right of the wheelchair respectively and block the wheels by holding on to the spokes.
Once assistant 1 and 2 are ready, assistant 3 should press the brake release button (see Figure 4, “Labelling of main switch and brake release”). Assistants 1 and 2 will now feel a slight pressure on the wheels.
Assistants 1 and 2 can now move the wheelchair up the stairs by rotating the wheels backwards.
If one of the assistants gets tired, the process can be interrupted at any point and for as long as necessary by releasing the brake release button. The wheelchair will then simply come to a stop on the stairs.
Caution! Once the top of the stairs has been reached, the wheelchair must be guided gently over the edge. Assistant 3 has to prevent the wheelchair from tipping backwards by holding onto the top of the back support.
Evacuation from a stair if a track has fallen out of the guide
If a track has fallen out of the guidance system, you should stop immediately and proceed according to Rubber Track Fell out of the Guidance System.
