  • Page 55: Drive Mode (Balancing)

    Scewo AG 5.5. DRIVE MODE (BALANCING) Scewo BRO drives and balances itself on a single axle. By activating drive mode the tracks and support system are raised automatically. In doing so, the unevenness of the surface is automati- cally compensated for as much as possible. The user should always remain seated in a relaxed position and lean against the back support.
  • Page 56 Scewo AG Scewo BRO V1.1 Keep a safe distance from drop-offs (cliffs) In drive mode, always keep a safe distance from drop-off/cliffs (such as stairs) and high steps. Never accelerate sharply towards a drop-off. You could underestimate the braking distance or the wheelchair could move in an unexpected way. There is a danger that you could tumble over the edge and die.

  • Page 57: Activating Drive Mode

    Scewo BRO V1.1 Scewo AG Do not activate drive mode without a seated occupant Drive mode must not be activated without somebody sitting in the wheelchair. Since the center of gravity alters significantly if there is nobody sitting in the wheel- chair, a stable driving behavior cannot be guaranteed.

    Scewo AG Scewo BRO V1.1 (a) Side view (b) Display on control panel Figure 40. Drive mode 5.5.2. RESTART AFTER A BALANCING ERROR The device monitors a range of critical safety parameters during the balancing mode. In certain circumstances, the wheelchair can enter an emergency shutdown and exit drive mode automati- cally.

  • Page 59: Exiting Drive Mode

    Scewo BRO V1.1 Scewo AG Possible causes of a balancing error Centre of gravity too far to the front/back (e.g. the wheelchair suddenly rolled forward): Adjust the center of gravity (e.g. change the angle of the back support, remove heavy objects from the backpack).

  • Page 60: Turns

    The control panel and the foot supports are more exposed than other parts of the wheelchair and can become trapped and damaged if the clearance is too small. Scewo recommends maintaining the following minimum clearance from fixed objects when you are in drive mode: •...
  • Page 61 Scewo BRO V1.1 Scewo AG Figure 43. Thresholds may only be crossed at a 90° angle Make sure you have enough space when going over thresholds When crossing thresholds in drive mode, the wheelchair may accelerate sharply for a short time afterwards because of the braking effect exerted by the threshold and then move forwards.

  • Page 62: Slopes

    Automatic lowering of the tracks - reduce speed before going up and down slopes When you are driving fast on level ground, Scewo BRO automatically lowers the tracks slightly. If you towards an uphill slope quickly, the tracks can hit the ground at the front and the wheelchair will stop abruptly.

  • Page 63: Driving On Different Surfaces

    Descend slopes slowly. Particular care is required when driving down slopes as the wheelchair may pick up speed. When Scewo BRO detects that you are travelling on a slope, the tracks are automatically raised completely. The following maneuvers may cause the wheelchair to overturn or cause injury to the user if the instructions are not followed: •...

  • Page 64: Unexpected Movements Of The Wheelchair

CLIMBING UP STAIRS The user should always monitor the end of the stairs The sensors that detect the end of the stairs do not work reliably under all circum- stances. They were designed to be an auxiliary system. Even if the sensors have detected the end of the stairs, it may be that the system triggers the transition too late and you topple backwards.

  • Page 71: Maneuvering Mode

    Scewo BRO V1.1 Scewo AG 8. If the next set of stairs follows immediately (e.g. at an intermediate landing), it is best to cover the short distance on level ground directly in stair mode on the tracks. 9. Reverse at least 50 cm before switching back to drive mode.

  • Page 72: Climbing Down Stairs

    Scewo AG Scewo BRO V1.1 Maneuvering mode is automatically activated in stair mode when you are on level ground (not on the stairs). It enables you to turn on narrow landings (e.g. when the stairs continue in a different direction after a landing at a 90° angle) or to adjust your orientation in front of stairs: Make sure you are in stair mode and on level ground.

  • Page 73: Suitable Stairs

    Scewo BRO V1.1 Scewo AG Check that the edge of the top step has been detected correctly The tracks should lift up once the first step has been detected, and converge to the incline of the stairs. In rare cases, the beginning of the stairs may be detected too early.
  • Page 74 Scewo BRO V1.1 Scewo BRO is suitable for most straight and dry stairs. If you are unsure whether a flight of stairs is suitable, always try to climb them from the bottom first, never from the top! Once the wheelchair has completely climbed the first two steps (tracks no longer touch the lowest level), shake the wheelchair strongly to test its stability and traction.

  • Page 102 Scewo BRO V1.1 Do not transport the charger with Scewo BRO The charger is not designed to be transported with Scewo BRO. The charger could be damaged by vibrations and other environmental conditions. The wheelchair charging socket is on the left side.

    This backup battery will be exhausted after approx. 20-30 minutes and the brakes will lock automatically.

    Scewo BRO V1.1 Scewo AG Caution on thresholds Do not allow yourself to be pulled down over thresholds. The wheelchair could topple over backwards. If going over a threshold cannot be avoided, warn the person assisting you that they may have to support the wheelchair from behind if it tips backwards.

    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.
