SAFETY
MANDATORY! Do not operate your ne po er chair for the first time ithout completely reading
and understanding this o ners manual.
Your power chair is a state-of-the-art life-enhancement device designed to increase mobility. Pride provides an extensive
variety of products to best fit the individual needs of the power chair user. Please be aware that the final selection and
purchasing decision regarding the type of power chair to be used is the responsibility of the power chair user, who is
capable of making such a decision, and his/her healthcare professional (i.e., medical doctor, physical therapist, etc.).
The contents of this manual are based on the expectation that a mobility device expert has properly fitted the power chair
to the user and has assisted the prescribing healthcare professional and/or the Quantum Rehab Specialist in the instruction
process for the use of the product.
There are certain situations, including some medical conditions, where the power chair user will need to practice operating
the power chair in the presence of a trained attendant. A trained attendant can be defined as a family member or care
professional specially trained in assisting a power chair user in various daily living activities.
As you begin using your power chair during daily activities, you will probably encounter situations in which you will need
some practice. Simply take your time and you will soon be in full and confident control as you maneuver through doorways,
on and off of elevators, up and down ramps, and over moderate terrain.
Below are some precautions, tips, and other safety considerations that will help the user become accustomed to operating
the power chair safely.
Modifications
Pride has designed and engineered your power chair to provide maximum mobility and utility. A wide range of accessories
is available from your Quantum Rehab Specialist to further customize your power chair to better suit your needs and/or
preferences. However, under no circumstances should you modify, add, remove, or disable any feature, part, or function
of your power chair.
WARNING! Do not modify your po er chair in any ay not authorized by Pride. Unauthorized
modifications may result in personal injury and/or damage to your po er chair.
Pre-Ride Safety Check
Get to know the feel of your power chair and its capabilities. Pride recommends that you perform a safety check before
each use to make sure your power chair operates smoothly and safely.
Perform the following inspections prior to using your power chair:
nCheck for proper tire inflation. Maintain but do not exceed 35 psi (2.4 bar) in each tire (if equipped with pneumatic tires).
nCheck all electrical connections. Make sure they are tight and not corroded.
nCheck all controller connections to the power base. Make sure they are secured properly.
nCheck the brakes. See VIII. Care and Maintenance.
nCheck battery charge. See VI. Batteries and Charging.

II. SAFETY
Weight Limitations
Your power chair is rated for a maximum weight capacity. Please refer to the specifications table for this limit.
WARNING! Exceeding the eight capacity voids your arranty and may result in personal injury
and/or damage to your po er chair. Pride ill not be held responsible for injuries and/or property
damage resulting from failure to observe eight limitations.
WARNING! Do not carry passengers on your po er chair. Carrying passengers on your po er
chair may result in personal injury and/or property damage.
Tire Inflation
If your power chair is equipped with pneumatic tires, you should check or have the air pressure checked regularly. Proper
inflation pressures will prolong the life of your tires and help ensure the smooth operation of your power chair.
WARNING! It is important that 35 psi (2.4 bar) tire pressure be maintained in pneumatic tires at all
times. Do not underinflate or overinflate your tires. Lo pressure may result in loss of control, and
overinflated tires may burst. Failure to maintain 35 psi (2.4 bar) tire pressure in pneumatic tires at
all times may result in tire and/or heel failure, causing serious personal injury and/or damage to
your po er chair.
WARNING! Inflate your po er chair drive tires from a regulated air source ith an available pressure
gauge. Inflating your tires from an unregulated air source could overinflate them, resulting in a
burst tire and/or personal injury.
Incline Information
More and more buildings have ramps with specified degrees of inclination, designed for easy and safe access. Some ramps
may have turning switchbacks (180-degree turns) that require you to have good cornering skills on your power chair.
nProceed with extreme caution as you approach the downgrade of a ramp or other incline.
nTake wide swings with your power chairs front wheels around any tight corners. If you do that, the power chairs rear
wheels will follow a wide arc, not cut the corner short, and not bump into or get hung up on any railing corners.
nhen driving down a ramp, keep the power chairs speed adjustment set to the slowest speed setting to ensure a
safely controlled descent. See VII. Operation.
nAvoid sudden stops and starts.
hen climbing an incline, try to keep your power chair moving. If you must stop, start up again slowly and then accelerate
cautiously. hen driving down an incline, set your power chair to the slowest setting and drive in the forward direction
only. If your power chair starts to move down the incline faster than you anticipated or desired, allow it to come to a
complete stop by releasing the joystick, then push the joystick forward slightly to ensure a safely controlled descent.
WARNING! When climbing an incline, do not zigzag or drive at an angle up the face of the incline.
Drive your po er chair straight up the incline. This greatly reduces the possibility of a tip or a fall.
Al ays exercise extreme caution hen negotiating an incline.
WARNING! You should not travel up or do n a potentially hazardous incline (i.e., areas covered
ith sno , ice, cut grass, or et leaves).
WARNING! When on any sort of an incline or decline, never place the po er chair in free heel
mode hile seated on it or standing next to it. Doing so may result in personal injury and/or
damage to your po er chair.
WARNING! Never travel do n an incline back ards. This may result in personal injury.

II. SAFETY
Figure 1. Maximum Safe Slope (Ascending and Descending)
WARNING! Even though your po er 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 po er chair,
resulting in personal injury and/or damage to your po er chair.
In compliance with the Americans with Disabilities Act of 1990, all handicap public access ramps are required to have a
maximum slope of 5° (8.7%). Therefore, Pride recommends that the maximum slope of an incline you attempt to safely
ascend or descend on your power chair does not exceed 5° (8.7%). See figure 1.
WARNING! Any attempt to climb or descend a slope steeper than 5° (8.7%) may put your po er
chair in an unstable position and cause it to tip, resulting in personal injury.
Braking Information
Your power chair is equipped with two powerful brake systems:
1. Regenerative  uses electricity to rapidly slow the vehicle when the joystick returns to the center/stop position.
2. 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
hile your power chair is equipped with four caster wheels, excessively high cornering speeds can still create the possibil-
ity 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. This greatly reduces the possibility of a
tip or fall. To avoid personal injury and/or property damage, al ays exercise common sense hen
cornering.
Public Streets and Road ays
WARNING! You should not operate your po er chair on public streets and road ays. Be a are
that it may be difficult for traffic to see you hen you are seated on your po er chair. Obey all
local pedestrian traffic rules. Wait until your path is clear of traffic, and then proceed ith extreme
caution.
