GENERAL GUIDELINES
MANDATORY! Do not operate your new power chair for the first time without completely reading
and understanding this owner’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 Pro-
vider 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 you become accustomed to oper-
ating your 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 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. Do not use
accessories if they have not been tested or approved for Pride products.
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:
Check for proper tire inflation. Maintain but do not exceed the psi/bar/kPa air pressure rating indicated on 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 power base. Make sure they are secured properly.
Check the brakes. See VII. “Care and Maintenance.”
Check battery charge. See VI. “Batteries and Charging.”
NOTE: If you discover a problem, contact your Quantum Rehab Provider for assistance.
II. SAFETY

Weight Limitations
Your power chair is rated for a maximum weight capacity. Please refer to the specifications table for this limit.
Keep in mind that the maximum weight capacity includes the combined weight of the user and any accessories
mounted to the power chair.
WARNING! Stay within the specified weight capacity of your power chair. Exceeding the weight
capacity voids your warranty. Pride will not be held responsible for injuries and/or property
damage resulting from failure to observe weight limitations.
WARNING! Do not carry passengers on your power chair. Carrying passengers on your power
chair may affect the center of gravity, resulting in a tip or a fall.
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 the psi/bar/kPa air pressure rating indicated on the tire 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 the
psi/bar/kPa air pressure rating indicated on the pneumatic tires at all times may result in tire
and/or wheel failure.
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.
NOTE: If the tire on your power chair lists the psi rating only, use the following conversion formulas to find
the bar or kPa rating: bar = psi x 0.06895; kPa = psi x 6.89476.
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.
Take 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 ensure
a safely controlled descent.
Avoid 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 speed 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 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 sort of an incline or decline, never place the power chair in freewheel
mode while seated on it or standing next to it.
WARNING! Never travel down an incline backward. Doing so may cause the power chair to tip.
II. SAFETY

Quantum 1121 Series www.pridemobility.com 9
Freewheel Mode
Your power chair is equipped with two manual freewheel levers 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.
“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. 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 center/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 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 and maintain a stable center of gravity.
This greatly reduces the possibility of a tip or fall.
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 stabilize the chair. Failure to heed
may 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 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.
II. SAFETY

Public Streets and Roadways
WARNING! You should not operate your power chair on public streets and roadways. Be aware
that it may be difficult for traffic to see you when you are seated on your power chair. Obey all
local pedestrian traffic rules. Wait until your path is clear of traffic, and then proceed with
extreme caution.
Outdoor Driving Surfaces
Your 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.
Avoid driving on uneven terrain and/or soft surfaces.
Avoid tall grass that can entangle the running gear.
Avoid loosely packed gravel and sand.
Do not use your power chair in fresh or salt water.
Do not use your power chair at the edge of a stream, lake, or ocean.
If you feel unsure about a driving surface, avoid that surface.
Inclement Weather Precautions
Exposure of your power chair to inclement weather conditions should be avoided whenever possible. If suddenly
caught up in rain, snow, severe cold or heat while operating your power chair, proceed to shelter at the earliest
opportunity. Thoroughly dry your power chair before storing, charging, or operating your power chair.
WARNING! Operating in rain, snow, salt, mist/spray conditions, and on icy/slippery surfaces can
have an adverse effect on the electrical system. Maintain and store your power chair in a dry
and clean condition.
WARNING! Prolonged exposure to hot or cold conditions may affect the temperature of
upholstered and non-upholstered items on the power chair, possibly resulting in skin irritation.
Exercise caution when using your power chair in extremely hot or cold conditions or when
exposing your power chair to direct sunlight for prolonged periods of time.
Stationary Obstacles (Steps, Curbs, etc.)
Proceed with extreme caution when driving near raised surfaces, unprotected ledges and/or drop-offs (curbs,
porches, stairs, etc.). Be sure your power chair is traveling perpendicular to any curb you may be required to navigate.
To navigate up over a curb or stationary obstacle:
1. Approach the curb or obstacle slowly, and make sure the power chair is traveling perpendicular to the obstacle.
See figure 2.
2. Increase the forward speed just before the front wheels come in contact with the obstacle.
3. Reduce the forward speed only after the rear wheels have cleared the obstacle.
To navigate down a curb or stationary obstacle:
1. Approach the curb or obstacle slowly, and make sure the power chair is traveling perpendicular to the obstacle.
See figure 2.
2. Reduce the forward speed just before the front wheels come in contact with the obstacle.
3. Increase the forward speed only after the rear wheels have cleared the obstacle and you are once again on a
level surface.
WARNING! Even though your power chair may be capable of handling greater obstacles, Pride
recommends that you do not attempt to negotiate a curb that has a height greater than 2 in.
(5 cm). Doing so could cause instability in your power chair.
WARNING! Do not attempt to have your power chair proceed backward down any step, curb, or
other obstacle. This may cause the power chair to tip.
II. SAFETY

Quantum 1121 Series www.pridemobility.com 11
Stairs and Escalators
Power chairs are not designed to travel up or down stairs or escalators. Always use an elevator.
WARNING! Never use your power chair to negotiate steps or escalators.
Doors
Determine if the door opens toward or away from you.
Drive your power chair gently and slowly forward to push the door open. Or drive your power chair gently
and slowly backward to pull the door open.
Elevators
Modern elevators have a door edge safety mechanism that, when pushed, reopens the elevator door(s).
If you are in the doorway of an elevator when the door(s) begin to close, push on the rubber door edge or allow
the rubber door edge to contact the power chair and the door will reopen.
Use care that pocketbooks, packages, or power chair accessories do not become caught in elevator doors.
Lift/Elevation Products
If you will be traveling with your power chair, you may find it necessary to use a vehicle-mounted lift system or
elevation product to aid in transportation. Pride recommends that you closely review the instructions, specifica-
tions, and safety information set forth by the manufacturer of the lift/elevation product before using that product.
WARNING! Not all lift systems/elevation products are rated for use with an occupied mobility
device. Pride recommends that you do not remain seated in your power chair when it is being
used in connection with any type of lift system/elevation product unless:
That product is rated for occupied use by the manufacturer.
You are able to occupy your mobility device in strict conformity with the warnings,
instructions, specifications, and safety guidelines set forth by the manufacturer.
WARNING! Always turn off the power to the controller when you are being transferred via an
elevation product. Failure to do so may result in accidental joystick contact, resulting in
unintended movement and personal injury or product damage.
Motor Vehicle Transport
Pride recommends that you do not remain seated in your power chair while traveling in a motor vehicle. The
power chair should be stowed in the trunk of a car or in the back of a truck or van with batteries removed and
properly secured. In addition, all removable power chair parts, including the armrests, seat, front riggings, con-
troller, and shrouds should be removed and/or properly secured during motor vehicle transport.
WARNING! Do not sit on your power chair while it is in a moving vehicle.
WARNING! Always be sure your power chair and its batteries are properly secured when it is
being transported. Batteries should be secured in an upright position and protective caps should

Positioning Belts
Your Quantum Rehab Provider, therapist(s), and other healthcare professionals are responsible for determining
your requirement for a positioning belt in order to operate your power chair safely.
WARNING! If you require a positioning belt to safely operate your power chair, make sure it is
fastened securely in order to reduce the possibility of a fall from the power chair.
WARNING! The positioning belt is not designed for use as a seat belt in a motor vehicle. Nor is
your power chair suitable for use as a seat in any vehicle. Anyone traveling in a vehicle should
be properly belted into seats approved by the vehicle manufacturer.
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 VI. “Batteries and Charging.”
WARNING! Battery posts, terminals, and related accessories contain lead and lead
compounds. Wear goggles and gloves when handling batteries and wash hands after
handling.
WARNING! Power chair batteries are heavy. See specifications table. If you are
unable to lift that much weight, be sure to get help. Use proper lifting techniques and
avoid lifting beyond your capacity.
WARNING! Always protect the batteries from freezing and never charge a frozen
battery. Charging a frozen battery may result in damage to the battery.
WARNING! Connect your battery harnesses in the proper manner. RED (+) cables
must be connected to positive (+) battery terminals/posts. BLACK (-) cables must be
connected to negative (-) battery terminals/posts. Protective caps should be installed
over all battery terminals. REPLACE cables immediately if damaged.
Removable Parts
WARNING! Do not attempt to lift or move a power chair by any of its removable parts, including
the armrests, seat, front riggings, controller, and shrouds.
Preventing Unintended Movement
WARNING! If you anticipate being seated in a stationary position for an extended period of time,
turn off the power. This will prevent unexpected motion from inadvertent joystick contact. This
will also eliminate the possibility of unintended chair movement from electromagnetic (EM)
sources.
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 or if you have to reach over the back of the seat. Movements
such as these may change your center of gravity and the weight distribution of the power chair,
possibly causing your power chair to tip.
WARNING! Keep your hands away from the tires when driving. Be aware that loose fitting
clothing can become caught in drive tires.
II. SAFETY

Quantum 1121 Series www.pridemobility.com 13
WARNING! Before transferring, position yourself as far back as possible in the power chair seat
to prevent the power chair from tipping forward during transfer.
WARNING! Avoid putting all of your weight on the power chair armrests and do not use the
armrests for weight bearing purposes, such as transfers. Such use may cause the power chair
to tip, resulting in a fall from the power chair and personal injury.
WARNING! Avoid putting all of your weight on the front riggings. Such use may cause the power
chair to tip.
WARNING! The controller and controller bracket are non-load bearing items on your power chair.
Do not use the controller or controller bracket for weight bearing purposes, such as transfers.
Such use may cause damage to these components, resulting in a fall from the power chair or
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.
WARNING! Consult your physician if you are taking prescribed or over-the-counter medication or
if you have certain physical limitations. Some medications and limitations may impair your
ability to operate your power chair in a safe manner.
II. SAFETY
Figure 4. Ideal Transfer Position
Transfers
Transferring onto and off of your power chair requires
a good sense of balance. Always have an attendant or
healthcare professional present while learning to prop-
erly transfer yourself.
To eliminate the possibility of injury, Pride recom-
mends that you or a trained attendant perform the fol-
lowing tasks before attempting a transfer:
Turn off the power to the controller.
Ensure your power chair is not in freewheel mode.

cigarette smoking. You must adhere to the following safety guidelines if you decide to smoke
cigarettes while seated in your power chair.
Do not leave lit cigarettes unattended.
Keep ashtrays a safe distance from the seat cushions.
Always make sure cigarettes are completely extinguished before disposal.
Electromagnetic and Radio Frequency Interference (EMI/RFI)
WARNING! Laboratory tests have shown that electromagnetic and radio frequency waves can
have an adverse effect on the performance of electrically-powered mobility vehicles.
Electromagnetic and Radio Frequency Interference can come from sources such as cellular phones, mobile two-
way radios (such as walkie-talkies), radio stations, TV stations, amateur radio (HAM) transmitters, wireless com-
puter 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 performance of other
electrical devices located nearby, such as alarm systems.
NOTE: For further information on EMI/RFI, go to 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 1-800-424-8205 to report the incident.

The electronics tray is located on the back of the power base. See figure 6.
Main Circuit Breaker: The main circuit breaker is a safety feature built into your power chair. When the batteries
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 Quantum Rehab Provider.
Controller Connector: This is where the controller connects to the power module. Each controller uses a differ-
ent type of harness. Regardless of which type of controller is used, the harness must be secured to the seat assem-
bly and not allowed to drag on the floor.
Active-Trac Suspension
The Quantum 1121 is equipped with Active-Trac Suspension (ATS). ATS is a suspension system designed to
make your power chair traverse different types of terrain and obstacles while maintaining smooth operation. With
ATS, the front anti-tip wheels work in conjunction with the motor suspension to help you maneuver over obstacles
in excess of 3 in. (7.62 cm) in height.
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 your power chair over an
obstacle without the possibility of becoming “hung up” on the obstacle.
ATS 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.

IV. ASSEMBLY
INITIAL ASSEMBLY
Your power chair may require some assembly either before initial use or after transportation. It may also require
disassembly to make some comfort adjustments.
NOTE: Any nylon insert lock nut removed during the disassembly or adjustment of the power chair must be
replaced with a new nut. Nylon insert lock nuts should not be reused as it may cause damage to the nylon insert,
resulting in a less secure fit. Replacement nylon insert lock nuts are available at local hardware stores or
through your Quantum Rehab Provider.
Seat Installation
The Universal Mounting System (UMS) consists of universal parts that may be used on the Specialty Seat or any
high-back seat, regardless of seat width or seat depth. The two main components are aluminum extrusions that can
be mounted to the seat base. These extrusions attach to a pair of trapeze bars that are mounted to four steel towers.
NOTE: If your power chair is equipped with a Specialty Seat, Synergy Seat, or Synergy TRU-Balance, refer to
the information provided in separate manuals. If your power chair is equipped with a contoured seating system,
refer to the following information.
WARNING!Do not pick up the seat frame by the armrests. They are free to pivot, and you may
lose control of the seat if they do so.
