13.7 Braking the electric wheelchair
The braking mechanism; i.e. the process from initiating the braking process until the electric wheelchair
comes to a stop, depends very heavily on a number of factors, such as:
› Surface and nature of the surface being travelled on.
› Total weight of the electric wheelchair (vehicle plus driver).
L L
On braking during cruising speed at about 6km/h, your electric wheelchair has a braking distance of
about 1 metre!
L L
When the brake is engaged at high speeds, specially in downhill travel, the electric wheelchair may
roll or skid. For this reason, avoid braking suddenly!

For your own safety you must observe and follow the following advice during uphill and downhill travel:
› Set the seat position to its hindmost position and scantlings back slightly in order to prevent slipping.
› Always drive with your safety belt on.
› Avoid braking suddenly during downhill travel to prevent the the electric wheelchair from rolling or skid-
ding.
› During uphill and downhill travel, select a low drive level and speed to prevent you from losing control of
the electric wheelchair at any point.
› The stability of the electric wheelchair cannot be guaranteed during uphill or downhill travel involving a
slope of more than 7°; such travel will involve danger of the electric wheelchair tipping over.
› When going downhill, the power generated is channelled into the accumulators. If the battery was fully
charged on starting travel, the safety system switches to emergency stop, in order to prevent damage to
the vehicle's electronic components through electrical overload. If this should occur, switch on an electri-
cal device (e.g. the lights) to run down the battery, and then continue your journey.

During uphill and downhill travel, the brake release lever should be set to "LOCK". The motor brake
only functions in "LOCK" position. Otherwise, the vehicle will travel downhill with no brake being
applied.
