II. SAFETY
SAFETY
MANDATORY! Do not operate your new power chair for the first time without completely
reading and understanding this owner’s manual.
Y our 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 authorized Pride Provider 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 authorized Pride Provider 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 power chair in any way not authorized by Pride. Unauthorized modifications may result in personal injury and/or damage to your power 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 . See IX. “Care and Maintenance.”
Perform the following inspections prior to using your power chair:
! Check for proper tire inflation. Maintain 35 psi (2.4 bar) in each tire if equipped with pneumatic tires.
! Check all electrical connections. Make sure they are tight and not corroded.
! Check all controller connections to the electronics tray . Make sure they are secured properly .
! Check the brakes. See IX. “Care and Maintenance.”
! Check battery charge. See VIII. “Batteries and Charging.”

II. SAFETY
NOTE: If you discover a problem, contact your authorized Pride Provider for assistance.
Weight Limitations
Y our power chair is rated for a maximum weight capacity . Please refer to the specifications table for this limit.
WARNING! Exceeding the weight capacity voids your warranty and may result in personal
injury and/or dama ge to your power chair. Pride will not be held responsible for injuries
and/or property damage resulting from failure to observe weight limitations.
WARNING! Do not carr y passengers on your power chair. Carrying passengers on your
power 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 at least
once a week. 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. Low 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 wheel failure, causing
serious personal injury and/or damage to your power chair .
WARNING! Inflate your power chair drive tires from a regulated air source with 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.
! Proceed with extreme caution as you approach the downgrade of a ramp or other incline.
! T ake 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.
! When driving down a ramp, keep the power chair’s speed adjustment set to the slowest speed setting to en-
sure a safely controlled descent. See VII. “Operation.”
! A void sudden stops and starts.
When climbing an incline, try to keep your power chair moving. If you must stop, start up again slowly and then
accelerate cautiously . When 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.
Jazzy 1122 www.pridemobility .com 7
II. SAFETY
WARNING! When climbing an incline, do not zigzag or drive at an angle up the face of the
incline. Drive your power chair straight up the incline. This greatly reduces the possibility
of a tip or a fall. Always exercise extreme caution when negotiating an incline.
WARNING! You should not travel up or down a potentially hazardous incline (i.e., areas
covered with snow, ice, cut grass, or wet leaves).
WARNING! When on any sor t of an incline or decline, never place the power chair in
freewheel mode while seated on it or standing next to it. Doing so may result in personal
injury and/or damage to your power chair .
WARNING! Never trav el do wn an incline bac kwards. This may result in personal injury .
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
power chair in an unstable position and cause it to tip, resulting in personal injury .

Figure 1. Maximum Safe Angle (Ascending and Descending)
Braking Information
Y our 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
While your power chair is equipped with rear caster wheels and front 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. This greatly reduces the possibility of a tip or fall. T o avoid personal injury and/or property damage, always exercise common sense when cornering.

II. SAFETY
Outdoor Driving Surfaces
Y our power chair is designed to provide optimum stability under normal driving conditions—dry , level surfaces
composed of concrete, blacktop, or asphalt. However, Pride recognizes that there will be times when you will
encounter other surface types. For this reason, your power chair is designed to perform admirably on packed soil,
grass, and gravel. Feel free to use your power chair safely on lawns and in park areas.
! Reduce your power chair’ s speed when driving on uneven terrain and/or soft surfaces.
! Avoid tall grass that can entangle the running gear .
! A void loosely packed gravel and sand.
! If you feel unsure about a driving surface, avoid that surface.
Freewheel Mode
Y our power chair is equipped with a manual freewheel lever to allow for manual maneuverability by a trained
attendant. For more information about how to place your power chair into and out of freewheel mode, see III.
“Y our Power Chair.”
WARNING! Do not use your power chair in freewheel mode without an attendant present.
Personal injury may result.
WARNING! Do not attempt to personally place your power chair in freewheel mode while
seated on it. Personal injury may result. Ask an attendant for assistance if necessary.
WARNING! Do not place your power chair in freewheel mode while on an incline. The
chair could roll uncontrollably on its own, causing personal injury .
Stationary Obstacles (Steps, Curbs, etc.)
Proceed with extreme caution when driving near raised surfaces, unprotected ledges and/or drop-offs (curbs,
porches, stairs, etc.). The correct method for approaching a curb is illustrated in figure 2.
WARNING! Do not attempt to have your power chair climb or descend an obstacle that is
higher than two inches unless you have the assistance of an attendant.
WARNING! Do not attempt to have your power chair proceed backwards down any step,
curb, or other obstacle. This may cause the power chair to tip and cause personal injury .

can cause personal injury and/or damage to the power chair and electrical system. Maintain
and store your power chair in a dry and clean condition.
Reaching and Bending
Never reach, lean, or bend while driving your power chair. If it is absolutely necessary to reach, lean, or bend while
seated on your power chair, it is important to maintain a stable center of gravity and keep the power chair from
tipping. Pride recommends that the power chair user determine his/her personal limitations and practice bending
and reaching in the presence of a qualified healthcare professional.
WARNING! Do not bend, lean, or reach for objects if you have to pick them up from the floor by
reaching down between your knees. Movements such as these may change your center of gravity
and the weight distribution of the power chair. This may cause your power chair to tip, possibly
resulting in personal injury.
WARNING! Prevent personal injury! Keep your hands away from the tires when driving. Be aware
that loose fitting clothing can become caught in drive tires.
Batteries
In addition to following the warnings below , be sure to comply with all other battery handling information. For
more information about your power chair’s batteries, see VIII. “Batteries and Char ging.”
WARNING! Power chair ba tteries are heavy . See specifica tions table. If you are unable to lift that
much weight, be sure to get help. Lifting beyond your capacity can result in personal injury .
WARNING! Battery posts, terminals, and related accessories contain lead and lead compounds.
Wash hands after handling.
WARNING! Always protect the batteries from freezing and never charge a frozen battery . Charging
a frozen battery may result in personal injury and/or damage to the battery .
Preventing Unintended Movement
WARNING! If you anticipa te being seated in a stationary position for an extended period of time,
turn off the power . This will prevent une xpected motion from inadvertent joystick contact. This
will also eliminate the possibility of unintended chair movement from electromagnetic (EM)
sources. Failure to do so may result in personal injury.
Prescription Drugs/Physical Limitations
Users must exercise care and common sense when operating a power chair. This includes awareness of safety
issues when taking prescribed or over-the-counter drugs or when the user has specific physical limitations.

Electromagnetic and Radio Frequency Interference (EMI/RFI)
WARNING! Laboratory tests have shown tha t electromagnetic and radio frequency waves
can have an adverse affect on the performance of electrically-powered mobility vehicles.
Electromagnetic and Radio Frequency Interference can come from sources such as cellular phones, mobile twoway radios (such as walkie-talkies), radio stations, TV stations, amateur radio (HAM) transmitters, wireless
computer links, microwave signals, paging transmitters, and medium-range mobile transceivers used by emergency
vehicles. In some cases, these waves can cause unintended movement or damage to the control system. Every
electrically-powered mobility vehicle has an immunity (or resistance) to EMI. The higher the immunity level, the
greater the protection against EMI. This product has been tested and has passed at an immunity level of 20 V/m.
WARNING! Be aware that cell phones, two-way radios, laptops, and other types of radio
transmitters may cause unintended movement of your electrically-powered mobility vehicle
due to EMI. Exercise caution when using any of these items while operating your mobility
vehicle and avoid coming into close proximity of radio and TV stations.
WARNING! The addition of accessories or components to the electrically-powered mobility
vehicle can increase the susceptibility of the vehicle to EMI. Do not modify your power
chair in any way not authorized by Pride.
WARNING! The electrically-powered mobility vehicle itself can disturb the perfo r mance
of other electrical devices located nearby , such as alarm systems.
NOTE: For further information on EMI/RFI, visit the Resource Center on www.pridemobility.com. If
unintended motion or brake release occurs, turn your power chair off as soon as it is safe to do so. Call
Pride at 800-424-8205 to report the incident.

Electronics T ra y
The electronics tray is located on the rear of your power chair. The electronics tray is located underneath the rear
sliding door . The electronics tray consists of the ammeter, the battery char ger plug, the main circuit breaker,
accessory connector (optional equipment), and the controller harness connectors.
Ammeter: The ammeter displays the char ger’s current output in amps. For more information, see VIII. “Batteries
and Charging.”
Charger Power Cord Receptacle: This plug is used whenever your battery needs recharging.
Main Circuit Breaker: The main circuit breaker is a safety feature built into your power chair . When the batter -
ies and the motors are heavily strained (e.g., from excessive loads), the main circuit breaker trips to prevent
damage to the motors and the electronics. If the circuit trips, allow your power chair to “rest” for approximately
one minute. Next, push in the circuit breaker button, turn on the controller, and continue normal operation. If the
main circuit breaker continues to trip repeatedly , contact your authorized Pride Provider.
Accessory Connector (Optional): This is where the accessory harness connects to the controller (power seat,
lighting).
Controller Connector: This is where the controller connects to the power base. The VSI uses a large, 9-pin
connector (not shown). The Remote Plus and Europa use smaller, multi-pin communications cable connectors.

III. YOUR POWER CHAIR
Active-T rac Suspension
Y our power chair is equipped with Active-Trac Suspension (A TS). A TS is a suspension system designed to make
your power chair traverse different types of terrain and obstacles while maintaining smooth operation. W ith ATS,
the front anti-tip wheels work in conjunction with the motor suspension to help you maneuver over obstacles.
As the front anti-tip wheels come in contact with an obstacle, the front anti-tip wheel assembly is drawn upward.
At the same time, the motors are forced downward. This allows the motors to push the power chair over an
obstacle and limits the possibility of your power chair getting caught on the obstacle.
A TS also helps in day-to-day operating conditions. For instance, when you release the joystick your power chair
begins to slow down. As the chair slows down, the front anti-tip wheels will automatically drop toward the ground.
This will reduce the forward tip that is typically encountered with center-wheel drive chairs.
Rear Suspension
Y our power chair is equipped with a rear suspension system. See figure 9. This suspension system works in
conjunction with the ATS and is designed to maintain a smooth ride when driving over rough terrain and up and
down curbs. This system works by allowing the caster forks to respond to weight transfers and uneven terrain. The
rear caster wheels will pivot as you drive over obstacles. This system also enhances performance when the front antitip wheels are set lower to the surface.
