Figure 1. Maximum Safe Slope (Ascending and Descending)
WARNING! If your power chair is equipped with a reclining seatback, do not attempt to negotiate
inclines with the seat in a reclined position. Do not attempt to negotiate obstacles with the seat
in a reclined position unless an attendant is present to help stabilise the chair. Failure to heed
could result in the power chair tipping over.
WARNING! Even though your power chair is capable of climbing slopes greater than those illustrated
in figure 1, do not, under any circumstances, exceed the incline guidelines or any other
specifications presented in this manual. Doing so could cause instability in your power chair.
Pride recommends that the maximum slope of an incline you attempt to safely ascend or descend on your power chair does
not exceed 10.5% (6°). See figure 1.
WARNING! Any attempt to climb or descend a slope steeper than 10.5% (6°) may put your power
chair in an unstable position and cause it to tip.
Freewheel Mode
Your power chair is equipped with two manual freewheel levers to allow for manual manoeuvreability by a trained atten-
dant. For more information about how to place your power chair into and out of freewheel mode, see III. “Your Power
Chair.”
WARNING! Do not use your power chair in freewheel mode without an attendant present.
WARNING! Do not attempt to personally place your power chair in freewheel mode
while seated on it. Ask an attendant for assistance if necessary.
WARNING! Do not place your power chair in freewheel mode while on an incline or
decline. This could cause the chair to roll uncontrollably on its own.
Braking Information
Your power chair is equipped with two powerful brake systems:
!
Regenerative — uses electricity to rapidly slow the vehicle when the joystick returns to the centre/stop position.
!
Disc Park Brake — activates mechanically after regenerative braking slows the vehicle to near stop, or when power is
removed from the system for any reason.
Cornering Information
While your power chair is equipped with front castor wheels and rear anti-tip wheels, excessively high cornering speeds can
still create the possibility of tipping. Factors which affect the possibility of tipping include, but are not limited to: cornering
speed, steering angle (how sharply you are turning), uneven road surfaces, inclined road surfaces, riding from an area of low
traction to an area of high traction (such as passing from a grassy area to a paved area – especially at high speed while turning)
and abrupt directional changes. High cornering speeds are not recommended. If you feel that you may tip over in a corner,
reduce your speed and steering angle (i.e., lessen the sharpness of the turn) to prevent your power chair from tipping.
WARNING! When cornering sharply, reduce your speed and maintain a stable centre of gravity.
This greatly reduces the possibility of a tip or fall. Always exercise common sense when cornering.
