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 Dealer
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 manoeu-
vre through doorways, on and off of lifts, 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 Dealer to further customise your power chair to better suit your
needs and/or preferences. However, under no circumstances should you modify, add, remove or disable any fea-
ture, part or function of your power chair.
WARNING! Do not modify your power chair in any way not authorised by Pride.
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 tyre inflation. Maintain but do not exceed the psi/bar/kPa air pressure rating indicated on
each tyre if equipped with pneumatic tyres.
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 Dealer for assistance.

Quantum 1650 www.pridemobility.com 11
II. SAFETY
Weight Limitations
Your power chair is rated for a maximum weight capacity. Please refer to the specifications table for this limit.
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 centre of gravity, resulting in a tip or fall.
Tyre Inflation
If your power chair is equipped with pneumatic tyres, you should check or have the air pressure checked regularly.
Proper inflation pressures will prolong the life of your tyres 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 tyres be
maintained in pneumatic tyres at all times. Do not underinflate or overinflate your tyres. Low
pressure may result in loss of control, and overinflated tyres may burst. Failure to maintain the
psi/bar/kPa air pressure rating indicated on the pneumatic tyres at all times may result in tyre
and/or wheel failure.
WARNING! Inflate your power chair drive tyres from a regulated air source with an available
pressure gauge. Inflating your tyres from an unregulated air source could overinflate them,
resulting in a burst tyre and/or personal injury.
Note: If the tyres on your power chair list 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 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 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! 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 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! 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.

12 www.pridemobility.com Quantum 1650
II. SAFETY
WARNING! Never travel down an incline rearward. Doing so may cause the power chair to tip.
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 stabilise 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 8.7% (5°). See figure 1.
WARNING! Any attempt to climb or descend a slope steeper than 8.7% (5°) 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)
Freewheel Mode
Your power chair is equipped with a manual freewheel system to allow for manual manoeuvrability 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 or
decline. 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 centre/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 castor wheels in back and anti-tip wheels in front, 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.

Quantum 1650 www.pridemobility.com 13
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 tarmac. However, Pride recognises 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.
PROHIBITED! 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 the 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, Kerbs, etc.)
Proceed with extreme caution when driving near raised surfaces, unprotected ledges and/or drop-offs (kerbs,
porches, stairs, etc.). Be sure your power chair is traveling perpendicular to any kerb you may be required to navigate.
To navigate up over a kerb or stationary obstacle:
1. Approach the kerb 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 kerb or stationary obstacle:
1. Approach the kerb 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 kerb that has a height greater than 5 cm (2
in.). Doing so could cause instability in your power chair.
WARNING! Do not attempt to have your power chair proceed rearward down any step, kerb or
other obstacle. This may cause the power chair to tip.

II. SAFETY
Stairs and Escalators
Power chairs are not designed to travel up or down stairs or escalators. Always use a lift.
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 rearward to pull the door open.
Lifts
Modern lifts have a door edge safety mechanism that, when pushed, reopens the lift door(s).
If you are in the doorway of a lift 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 handbags, packages or power chair accessories do not become caught in lift doors.
Lift Systems/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 boot 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.

II. SAFETY
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
be installed on the battery terminals. Batteries should not be transported with any flammable or
combustible items.
Positioning Belts
Your Quantum Rehab Dealer, therapist(s) and other healthcare professionals are responsible for determining your
requirement for a positioning belt in order to operate your power chair safely. Typically, the positioning belt is
not designed for use as a restraining device in a motor vehicle.
Positioning belts should be installed as detailed in this manual. See V. “Comfort Adjustments.” Once installed,
the belt should be placed across the pelvis as determined by the user’s healthcare dealer. Anchor points of the
positioning belts should be located so that a projected side-view angle of the pelvis is between 30°-75° of hori-
zontal depending on the user’s weight, posture and seat cushion thickness.
WARNING! If you require a positioning belt to safely operate your power chair, make sure it is
fastened securely. Serious personal injury may result if you 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.”
MANDATORY! 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.

16 www.pridemobility.com Quantum 1650
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 centre 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 centre of gravity and the weight distribution of the power chair.
WARNING! Keep your hands away from the tyres when driving. Be aware that loose
fitting clothing can become caught in drive tyres.
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.
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 and
personal injury.
WARNING! Avoid putting all of your weight on the front riggings. Such use may cause the power
chair to tip.
II. SAFETY
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 properly 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. See III. “Your Power Chair.”
Turn both castor wheels toward the transfer
destination to improve power chair stability
during transfer.
Make sure both armrests are flipped up or
removed from your power chair.
Flip up the foot platform or move the leg rests
aside; this will help to keep your feet from getting
caught on the front rigging during the transfer.
Reduce the distance between your power chair
and the object you are transferring onto. See
figure 4.

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 authorised 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 unin-
tended motion or brake release occurs, turn your power chair off as soon as it is safe to do so. Contact your
Quantum Rehab Dealer to report the incident.

Electrical Components
The electrical components are located on the power base. See figure 7.
Thermal Fuse: The thermal fuse is located on the front of the power base. If the batteries and the motors are
heavily strained (e.g., from excessive loads), the thermal fuse will reduce the amount of current going to the
electronic controller by 60%. The current will automatically return to 100% when the fuse cools to within its
normal operating temperature range.
Power Module: The power module supplies battery power to the motors. It is connected to the controller through
a controller harness.
Battery Connectors: The battery connectors provide a connection between the battery wiring harnesses and the
power module. The standard battery package has two battery connectors. The extended range package has four
battery connectors.
Circuit Breaker (not shown): The circuit breaker is self-resetting and nonserviceable. Contact your Quantum
Rehab Dealer if the circuit breaker resets itself repeatedly.
