SAFETY
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 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.Atrained 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.Awide 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 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.
Perform the following inspections prior to using your power chair:
n Check for proper tire inflation. Maintain but do not exceed 35 psi (2.4 bar) in each tire (if equipped with pneumatic tires).
n Check all electrical connections. Make sure they are tight and not corroded.
n Check all controller connections to the power base. Make sure they are secured properly.
n Check the brakes. See VIII. “Care and Maintenance.”
n Check battery charge. See VI. “Batteries and Charging.”
NOTE: If you discover a problem, contact your Quantum Rehab Specialist for assistance.

Weight Limitations
Your 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 damage 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 carry 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 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. 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.
n Proceed with extreme caution as you approach the downgrade of a ramp or other incline.
n 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.
n When 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.”
n 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 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. Doing so may result in personal injury and/or
damage to your power chair.
WARNING! Never travel down an incline backwards. This may result in personal injury.

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,
resulting in personal injury and/or damage to your power chair.
In compliance with theAmericans with DisabilitiesAct 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 Slope (Ascending and Descending)
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
While 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, always exercise common sense when
cornering.
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.

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. 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.
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.
nReduce your power chair’s speed when driving on uneven terrain and/or soft surfaces.
nAvoid tall grass that can entangle the running gear.
nAvoid loosely packed gravel and sand.
nIf you feel unsure about a driving surface, avoid that surface.
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 2 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.
Figure 2. Correct Curb Approach
Figure 3. Incorrect Curb Approach
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. You may cause injury to
yourself and to others and/or damage your power chair.

Transfers
Transferring onto and off of your power chair requires a
good sense of balance.Always have an attendant or health-
care professional present while learning to properly trans-
fer yourself.
To eliminate the possibility of injury, Pride recommends that
you or a trained attendant perform the following tasks be-
fore attempting a transfer:
n Turn the power off. See VII. “Operation.”
n Ensure your power chair is not in freewheel mode.
See III. “Your Power Chair.”
n Turn the caster wheels toward the transfer destination
to improve power chair stability during transfer.
n Make sure both armrests are flipped up or removed
from your power chair.
n Flip up the foot platform or move the leg rests aside;
this will help to keep your feet from getting caught on
the foot rigging during the transfer.
n Reduce the distance between your power chair and
the object you are transferring onto.
Figure 4. Ideal Transfer Position
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 and causing injury.
WARNING! Avoid using your armrests for weight bearing purposes. Such use may cause the power
chair to tip and cause personal injury.
WARNING! Avoid putting all of your weight on the foot riggings. Such use may cause the power
chair to tip and cause personal injury.
Doors
nDetermine if the door opens toward or away from you.
nDrive your power chair gently and slowly forward to push the door open. Or drive your power chair gently and slowly
backwards to pull the door open.
Elevators
Modern elevators have a door edge safety mechanism that, when pushed, reopens the elevator door(s).
nIf 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.
nUse 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 lift/elevation product to aid in transporta-
tion. Pride recommends that you closely review the instructions, specifications, and safety information set forth by the
manufacturer of the lift/elevation product before using that product.

Removable Parts
WARNING! Do not attempt to lift or move a power chair by any of its removable parts. Personal
injury and/or damage to the power chair may result.
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.
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.
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.
Alcohol
The power chair user must exercise care and common sense when operating his/her power chair. This includes awareness
of safety issues while under the influence of alcohol.
WARNING! Do not operate your power chair while you are under the influence of alcohol, as this
may impair your ability to operate your power chair in a safe manner.
Electromagnetic and Radio Frequency Interference (EMI/RFI)
WARNING! Laboratory tests have shown that 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 two-way
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.
PROHIBITED! To prevent unintended movement, turn off the power to the electrically-powered
mobility vehicle before using a cell phone, two-way radio, lap-top, or any other type of radio
transmitter. Avoid coming into close proximity of radio or 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.
tended 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.

BATTERIES AND CHARGING
The Quantum 500 uses two long-lasting, 12-volt, deep-cycle batteries. These batteries are sealed and maintenance free.
Since they are sealed, there is no need to check the electrolyte (fluid) level. Deep-cycle batteries are designed to handle a
longer and deeper discharge. Though they are similar in appearance to automotive batteries, they are not interchangeable.
Automotive batteries are not designed to handle a long, deep discharge, and also are unsafe for use in power chairs.
WARNING! Battery posts, terminals, and related accessories contain lead and lead compounds.
Wash hands after handling.
Charging the Batteries
The battery charger is essential in providing long life for your power chair batteries. It is designed to optimize your power
chair’s performance by charging the batteries safely, quickly, and easily.
WARNING! You must recharge your power chair’s batteries with the supplied off-board battery
charger. Do not use an automotive-type battery charger.
PROHIBITED! Removal of grounding prong can create electrical hazard. If necessary, properly
install an approved 3-pronged adapter to an electrical outlet having 2-pronged plug access. Failure
to heed could result in personal injury and/or property damage.
PROHIBITED! Never use an extension cord to plug in your battery charger. Plug the charger directly
into a properly wired standard wall outlet.

Frequently Asked Questions (FAQs)
Howdoesthechargerwork?
The battery charger takes the standard wall outlet voltage of 120 VAC (alternating current) and converts it to 24 VDC
(direct current). The power chair batteries use direct current to run your power chair. When the battery voltage is low, the
charger works harder to charge the battery.As the battery voltage approaches full charge, the charger doesn’t work as
hard to complete the charging cycle. When the battery is fully charged, the amperage from the charger is nearly at zero.
This is how the charger maintains a charge but does not overcharge the battery.
CanIuseadifferentbatterycharger?
Youshouldusethechargersuppliedwiththepowerchair.Itisthesafest,mostefficienttooltochargethebatteries.Wedo
not recommend using other types of chargers (e.g., an automotive battery charger).
NOTE: Your power chair’s charger will not operate after the batteries have been discharged to nearly zero
voltage. If this happens, call your Quantum Rehab Specialist for assistance.
How often must Icharge thebatteries?
Many factors come into play when deciding how often to charge the batteries.You may use your power chair all day on a
daily basis or you may not use it for weeks at a time.
n Daily Use
If you use your power chair on a daily basis, charge the batteries as soon as you are finished using your power chair.
Your power chair will be ready each morning to give you a full day’s service. It is recommended that you charge the
batteries 8 to 14 hours after daily use.
n InfrequentUse
If you use your power chair infrequently (once a week or less), you should charge the batteries at least once per week
for 12 to 14 hours.
NOTE: Keep your batteries fully charged and avoid deeply discharging your batteries. Do not charge the
batteries for more than 24 hours at a charging cycle.
How can I get maximum range or distance per charge?
Rarely do you have an ideal driving situation such as smooth, flat, hard terrain with no wind, hills, or curves. More often you
are presented with hills, sidewalk cracks, uneven and loosely packed surfaces, curves, and wind.All of these factors will
affect the distance or running time per battery charge. Below are a few suggestions for obtaining the maximum range per
charge:
n Always charge the batteries fully prior to your trip.
n Plan your trip in advance to avoid inclines if possible.
n Limit baggage weight to essential items.
n Try to maintain an even speed and avoid stop-and-go driving.
What type of batteries should I use?

WARNING! Corrosive chemicals contained in batteries. Use only AGM or Gel-Cell batteries to
reduce the risk of leakage or explosive conditions.
Why do my new batteries seem weak?
Deep-cycle batteries employ a much different chemical technology than that used in car batteries, nickel-cadmium (nicads),
or in other common battery types. Deep-cycle batteries are specifically designed to provide power, drain down their
charge, and then accept a relatively quick recharge.AGM and Gel-Cell batteries should be charged as often as possible.
They do not have a “memory” like nickel-cadmium batteries.
Weworkcloselywithourbatterymanufacturertoprovideabatterythatbestsuitsyourpowerchair’sspecificdemands.
Fresh batteries arrive regularly at Pride and are promptly shipped with a full charge. During shipping, the batteries encoun-
ter temperature extremes that may influence initial performance. Heat robs the charge from the battery, and cold slows the
power available and extends the time needed to recharge the battery (just as with a car battery).
It might take a few days for the temperature of the battery to stabilize and adjust to its new ambient temperature. More
importantly, it will take a few “charging cycles” (a partial drain— then a full recharge) to establish the critical chemical
balance that is essential to the battery’s peak performance and long life. It will be well worth it to take the time to break in
your battery properly.
NOTE: The useful life of a battery is quite often a reflection of the care it receives.
How can I ensure maximum battery life?
Afully charged deep-cycle battery will provide reliable performance and extended battery life. Keep your power chair’s
batteries fully charged whenever possible. Batteries that are regularly and deeply discharged, infrequently charged, or
stored without a full charge may be permanently damaged, causing unreliable power chair operation and limited battery life.
How should I store my power chair and its batteries?
If you do not use your power chair regularly, we recommend maintaining battery vitality by charging the batteries at least
once per week.
If you do not plan on using your power chair for an extended period, fully charge the batteries prior to storage. Disconnect
the battery harnesses and store the power chair in a warm, dry environment.Avoid temperature extremes, such as freezing
and excessively hot conditions, and never attempt to charge a frozen battery.Acold or frozen battery should be warmed
for several days prior to recharging.
What about public transportation?
AGM and Gel-Cell batteries are designed for application in power chairs and other mobility vehicles. These batteries are
FederalAviationAdministration (FAA) approved, allowing safe transportation on aircraft, buses, and trains, as there is no
dangerofspillageorleakage.Wesuggestyoucontactthecarrier’sticketcounterinadvancetodeterminethatcarrier’s
specific requirements.
What about shipping?
If you wish to use a freight company to ship your power chair to your final destination, repack your power chair in the
original shipping container and ship the batteries in separate boxes.

VSI ELECTRONIC CONTROLLER
The electronic controller is what you use to operate your power chair. The electronic controller enables you to move the
power chair, as well as monitor battery charge, electronic controller functions, and the condition of your electrical system.
TheVSI electronic controller is an integral electronic controller.All of the electronics necessary to operate the power chair
are contained in one module. See figure 23. Typically, the VSI is mounted to one of the armrests and is connected to the
motors and batteries at the power base. The VSI may be used to control some optional systems such as power elevating
leg rests.
The controller supplied with your power chair has been pre-programmed to meet the needs of the end user. The program
is set using either a personal computer with software provided by the controller manufacturer or with a hand-held program-
mer, also provided by the controller manufacturer.
WARNING! The controller program can affect speed, acceleration, deceleration, and braking. But
if it is programmed incorrectly or outside of the safe limits as determined by your healthcare
professional, it can create a dangerous situation. Only the power chair manufacturer, an autho-
rized representative of the manufacturer, or a trained service technician should program the
controller.
The VSI consists of:
1. joystick
2. keypad
3. off-board charger/programming socket
4. actuator connector (optional)
5. battery connector
6. motor connector
7. motor connector
Joystick
The joystick controls the direction and speed of your power
chair. When you move the joystick from the neutral (center)
position, the electromagnetic brakes release and allow your
power chair to move. The farther you push the joystick
from its neutral position, the faster your power chair moves.
When you release the joystick and allow it to return to the
neutral position, you engage the electromagnetic brakes.
This causes your power chair to decelerate and come to a
complete stop.
Figure 23. VSI Controller (Optional 6-key Shown)
WARNING! If your power chair begins to move in an unexpected manner, immediately release the
joystick. Unless the joystick is damaged, this action should stop your power chair.

as soon as possible; VSI operational, and electrical system OK.
NOTE: When the batteries approach a discharged state, the first red light will begin to slowly flash, remind-
ing you the batteries need to be charged immediately!
n Rapid flash of lights: Indicates a fault in the VSI or the electrical system. Refer to “VSI Error Codes.”
n Ripple side to side of lights: The joystick was not in the neutral position when the controller was turned on. If you
get “ripple side to side of lights,” turn off the controller, allow the joystick to return to the neutral position, then turn on
the controller.
NOTE: If you still get “ripple side to side of lights,” contact your Quantum Rehab Specialist.
Speed/Profile Keys
The speed/profile keys control either the speed setting or the drive profile. Press the speed/profile increase key to increase
the speed setting or change the drive profile to a higher number. Press the speed/profile decrease key to decrease the
speed setting or change the drive profile to a lower number. The speed setting or drive profile is displayed on the maximum
speed/profile indicator. If your power chair was programmed with a drive profile, contact your Quantum Rehab Specialist
for more information.
NOTE: We recommend that the first few times you operate your power chair, you use the lowest speed setting
until you become familiar with your new power chair.

Thermal Rollback
TheVSI controller is equipped with a thermal rollback circuit. This circuit monitors the temperature of the controller, which
roughly translates to motor temperature. In the event that the VSI controller becomes excessively hot (above 140° F), motor
current (amperage) is reduced. For every degree above 140° F, the motor current limit is reduced by .55 amps until theVSI
controller reaches 158° F, at which time the current output is reduced to zero. This reduces your power chair’s “power,”
which could also reduce your power chair’s speed, and allows the electrical components and motors to cool down. When the
temperature returns to a safe level, your power chair resumes its normal operation.
VSI Error Codes
TheVSI controller is designed with the user’s safety as the prime consideration. It incorporates many sophisticated self-
test features which search for potential problems at a rate of 100 times per second. If the VSI detects a problem either in
its own circuits or in the power chair’s electrical system, it may decide to stop the power chair, depending on the severity
of the problem. TheVSI is designed to maximize the user’s safety under all normal conditions. The table below identifies
the individual error codes. Error codes are displayed as a rapid flashing of the battery condition meter lights. If you get one
of these error codes, contact your Quantum Rehab Specialist.

CARE AND MAINTENANCE
Your Quantum 500 is a sophisticated power chair. Like any motorized vehicle, it requires routine maintenance checks.You
can perform some of these checks, but others require assistance from your Quantum Rehab Specialist. Preventive mainte-
nance is very important. If you follow the maintenance checks in this section as scheduled, you can help ensure that your
power chair gives you years of trouble-free operation. If you have any doubt as to your power chair’s care or operation,
contact your Quantum Rehab Specialist.
WARNING! Prevent injury. Do not service the power chair when the seat is occupied.
Your power chair, like most electrical equipment, is susceptible to damage from the elements. Avoid damp areas of
any kind.
WARNING! Direct exposure to water or dampness could cause the power chair to malfunction
electronically and mechanically. Water can cause electrical components to corrode and the chair’s
frame to rust.
Should your power chair come in contact with water:
1. Dry your power chair as thoroughly as possible with a towel.
2. Allow your power chair to sit in a warm, dry place for 12 hours to allow unseen water to evaporate.
3. Check the joystick operation and the brakes before using your power chair again.
4. If any inconsistencies are found, take your power chair to your Quantum Rehab Specialist.
