OPERATION
WARNING! Your power chair's road performance may be influenced by electromagnetic fields caused by mo-
bile telephones or other radiating devices, such as hand-held radios, radio and television stations, wireless
computer links, microwave sources, and paging transmitters.
WARNING! Your power chair can be a source of electromagnetic and radio frequency interference.
MAXIMUM RECOMMENDED GRADE
Pride performs extensive testing with on our power chair. Our results indicate that the maximum grade your power chair can
climb safely is 8.7% at maximum weight capacity. See figure 1. Seven percent is the angle of most handicap access ramps.
Any attempt to climb a steeper grade may put your power chair in an unstable position.

WARNING! Although your power chair may be capable of climbing grades greater than those illustrated above,
do not, under any circumstances, exceed the grade guidelines or any other specifications presented in this
manual. Doing so could cause instability in your power chair, resulting in personal injury and/or damage to
your power chair.
WARNING! Always exercise extreme caution when negotiating an incline. Do not zigzag or drive at an angle.
Drive your power chair straight up the incline. This greatly reduces the possibility of a tip or a fall.
WARNING! You should not travel up or down a potentially hazardous grade (i.e., areas covered with snow, ice,
cut grass, or wet leaves). Pride will not be held responsible for injuries and/or property damage resulting from
zigzagging, driving at an angle up the face of an grade, failing to exercise extreme caution when negotiating a
grade, and/or traveling on a low traction surface grade.
WARNING! When on any sort of a grade, never place the power chair in freewheel mode while seated on it or
standing next to it.
KERB CLIMBING
If you are going to attempt to climb onto a kerb, approach it slowly and head-on. Try to keep your power chair moving. If you
must stop in the middle of the climb, start again slowly and accelerate cautiously.
WARNING! The front anti-tip wheels may cause trouble when ascending or descending a kerb if they are not
adjusted correctly. Contact your authorised Pride provider for more information.
CORNERS
We do not recommend high cornering speeds. While your power chair is equipped with caster wheels and anti-tip wheels for
increased stability, excessively high cornering speeds can still create the possibility of tipping. Factors which affect the possi-
bility of tipping include, but are not limited to:
l cornering speed.
l steering angle (how sharply you are turning).
l riding on uneven road surfaces.
l riding on inclined road surfaces.
l 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).
l making abrupt directional changes.
WARNING! To avoid personal injury or property damage, always exercise common sense when cornering. If
the situation arises where you have to negotiate a sharp corner, reduce your speed and steering angle (i.e.,
lessen the sharpness of the turn). This greatly reduces the possibility of a tip or fall.
