SAFETY
WARNING! 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 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 X. “Care and Maintenance.”
Perform the following inspections prior to using your power chair:
n Check for proper tire inflation. Maintain 30-35 psi 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 electronics tray. Make sure they are secured properly.
n Check the brakes. See X. “Care and Maintenance.”
n Check battery charge. SeeVIII. “Batteries and Charging.”

NOTE: If you discover a problem, contact your authorized Pride provider 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 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 30-35 psi 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 30-35 psi 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 IX. “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.
Pride LX Series/Rev B/Feb 03

I I .
S A F E T Y
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.
In compliance with the Americans with Disabilities Act of 1990, all handicap public access ramps are required to
have a maximum slope of 5°. 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°. See figure 1.
WARNING! Any attempt to climb or descend a slope steeper than 5° 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
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 rear caster 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. To avoid personal injury and/or property damage, always exercise common sense
when cornering.
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.

Reduce your power chair’s speed when driving on uneven terrain and/or soft surfaces.
Avoid tall grass that can entangle the running gear.
Avoid loosely packed gravel and sand.
If you feel unsure about a driving surface, avoid that surface.
Freewheel Mode
Your 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 V. “Your
Pride LX.”
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.
Figure 2. Correct Curb Approach
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 backward down any step, curb, or
other obstacle. This may cause the power chair to tip and cause personal injury.
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.

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.
Doors
n Determine if the door opens toward or away from you.
n 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).
n 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.
n Use care that pocketbooks, packages, or power chair accessories do not become caught in elevator doors.
EMI & RFI
Laboratory tests performed by the Food and Drug Administration (FDA) have shown that radio waves can cause
unintended motion of electric mobility vehicles. Radio waves are a form of electromagnetic energy (EM). When
EM adversely affects the operation of an electronic device, it is called Electromagnetic Interference (EMI) or
Radio Frequency Interference (RFI). For more information, see III. “EMI/RFI.”
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
transportation. 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.
Motor Vehicle Transport
Currently, there are no standards approved for tie-down systems in a moving vehicle of any type to transport a
person while seated in a power chair.
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 recommends that you or a trained attendant perform the following tasks
before attempting a transfer:
n Turn the power off. See IX. “Operation.”
n Ensure your power chair is not in freewheel mode. See V. “Your Pride LX.”
n Turn both 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 the footrest up, or move the leg rests aside; this will help to keep your feet from getting caught on the
footrest or the leg rests during the transfer.
n Reduce the distance between your power chair and the object you are transferring onto.

Pride LX Series/Rev B/Feb 03
I I .
S A F E T Y
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 footrest. Such use may cause the power chair
to tip and cause personal injury.
Positioning Belts
Your authorized Pride 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. 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.
WARNING! Do not sit on your power chair while it is in a moving vehicle. Personal injury and/or
property damage may result.
WARNING! Always be sure your power chair and its batteries are properly secured when it is
being transported. Failure to do so may result in personal injury and/or damage to your power
chair.
Inclement Weather Precautions
WARNING! Pride recommends that you do not operate your power chair in icy or slippery conditions
or on salted surfaces (i.e., walks or roads). Such use may adversely affect the performance and
safety of your power chair, resulting in an accident and personal injury.
WARNING! Do not expose your power chair to any type of moisture at any time (rain, snow, mist,
or wash). Such exposure can damage your power chair. Never operate your power chair if it has
been exposed to moisture until it has dried thoroughly.
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.
Keep your hands away from the tires when driving.

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 Charging.”
WARNING! Power chair batteries weigh approximately 60 pounds each. 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 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.
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.

EMI/RFI
Laboratory tests performed by the Food and Drug Administration (FDA) have shown that radio waves can cause
unintended motion of power chairs. Radio waves are a form of electromagnetic energy. When this energy adversely
affects the operation of an electronic device, it is called Electromagnetic Interference (EMI) or Radio Frequency
Interference (RFI).
WARNING! Radio waves may interfere with the control of power chairs.
Frequently Asked Questions (FAQs)
The following FAQs summarize what you should know about EMI/RFI. Use this information to minimize the risk
that EMI/RFI will affect your power chair.
Where do radio waves come from?
Radio waves are emitted from the antennas of cellular phones, mobile two-way radios (such as walkie-talkies),
radio stations, TV stations, amateur radio (HAM) transmitters, wireless computer links, microwave sources, and
paging transmitters. Radio waves are a form of electromagnetic energy. Because electromagnetic energy is more
intense closer to the transmitting antenna (source of emission), the electromagnetic energy fields from two-way
radios are of special concern to power chair users.
If my power chair is affected by EMI/RFI, what kind of motion should I expect?
This is hard to predict. It would depend on a number of factors:
n Strength of the radio waves
n Construction of the power chair
n Position of the power chair (whether it is on level ground or on an incline)
n Whether or not the power chair is in motion
An affected power chair’s movement can be erratic. It may move by itself or come to a sudden stop. Furthermore,
it is possible for EMI/RFI to unexpectedly release the brakes on a power chair. Some intense sources of EMI/RFI
can even damage the control system of the power chair.
Is there any way to know for sure whether radio waves are responsible for the unintended motion of my
power chair?
Unfortunately, interference from radio wave sources may be difficult to recognize, since the signals from these
sources are invisible and may be intermittent. However, the FDA recommends that you report all incidents of
unintended motion or brake release to the power chair manufacturer and, if possible, note whether there was a
radio wave source nearby at the time of the incident.
Has anyone been hurt from erratic, unintended motion of power chairs?
The FDA has reports of injuries that resulted from the apparent uncontrolled motion of power chairs. However, it
is unclear how many of these incidents were actually caused by radio wave interference.
Pride LX Series/Rev B/Feb 03

I I I .
E M I / R F I
Are all power chairs susceptible to EMI/RFI?
Each make and model of chair differs in its ability to resist electromagnetic interference. That is, each has a
particular level of “immunity” to interference, measured in volts per meter (V/m). A higher immunity level offers
greater protection. In other words, a power chair with a high immunity level is less likely to be affected by a strong
radio source than one with a low immunity level.
What is the FDA doing about the problem?
The FDA has written to the manufacturers of power chairs and requested that they test their new products to be
sure that they provide a reasonable degree of immunity against EMI/RFI. The letter states that power chairs should
have an immunity of at least 20 V/m. This provides a reasonable degree of protection against the common sources
of EMI/RFI.
The FDA has also requested that these manufacturers clearly label their products with the immunity level, or state
that the immunity level is not known. The labeling and informational material supplied with the power chair must
explain what the immunity level means, and the labeling or informational material must warn users about the
possibility of EMI/RFI and how to avoid it. In addition, the FDA has recommended that manufacturers establish an
educational program to inform users of power chairs, and their caregivers, about the problems associated with
EMI/RFI, and the actions they can take to minimize the risk.
What can I do to find out if my power chair is likely to be affected by EMI/RFI?
If you’ve had your power chair for a long time and haven’t experienced any unintended motion, it is not likely that
you will have problems in the future. But it is always possible that problems could arise if you are close to a source
of radio waves. Therefore, it is very important to be alert to this possibility. The Pride LX meets or exceeds an
immunity level of at least 20 V/m.
What can I do to reduce the risk that my power chair could be affected by EMI/RFI?
Here are some precautions you can take:
n Do not turn on or use hand-held personal communications devices, such as citizens band (CB) radios and
cellular phones, while the power chair is on.
n Be aware of nearby transmitters, such as radio or TV stations and hand-held or mobile two-way radios, and
try not to come close to them. For example, if you are in a power chair with an immunity level of 20 V/m,
you should remain at least three feet from a hand-held two-way radio and ten feet from a mobile two-way
radio.
n Be aware that adding accessories and/or components, or modifying the power chair may make it more
susceptible to interference from radio wave sources. There is no easy way to evaluate their effect upon the
overall immunity of the power chair.
What should I do if my power chair moves unexpectedly?
If unintended motion or brake release occurs, turn the power chair off as soon as it is safe to do so. Call Pride at
800-424-8205 to report the incident.

VI I I . BATTERIES AND CHARGING
Your Pride LX uses two long-lasting, 12-volt, deep-cycle batteries that 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 deep
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! Always protect batteries from freezing temperatures and never attempt to charge a frozen
battery. This damages the battery and may cause personal injury. Attempting to charge a battery in
freezing conditions does not prevent a battery from freezing.
Charging Your Batteries
Your Pride LX is equipped with an off-board charger. Typically, off-board chargers plug into the joystick/controller.
Refer to the instructions printed on the charger.
WARNING! You must recharge your Pride LX’s batteries with the supplied off-board charging system. Do
not use an automotive-type battery charger.
WARNING! Never use an extension cord to plug in your battery charger. Plug the charger directly into a
properly wired standard wall outlet.
Battery Break-in
To break in your Pride LX’s new batteries for maximum efficiency:
1. Fully recharge any new battery prior to its initial use. This will bring the battery up to about 90% of its peak
performance.
2. Drive your Pride LX about the house. Move slowly at first and don’t stray too far until you grow accustomed to
the controls and break-in the batteries.
3. Give the batteries another full charge of 8 to 14 hours and drive the Pride LX again. The batteries will now
perform at over 90% of their potential.
4. After four or five charging cycles, the batteries will top off at 100% charge and last for an extended period.
Battery Disposal and Recycling
If you encounter a damaged or cracked battery, immediately enclose it in a plastic bag and call your authorized
Pride provider for instructions or disposal. Your authorized Pride provider will also have the necessary information
on battery recycling, which is our recommended course of action.

VII I . BATTERIES AND CHARGING
Frequently Asked Questions (FAQs)
Can I use a different battery charger?
We do not recommend using other types of chargers (e.g., an automotive battery charger) other than the one
suggested by your authorized Pride provider.
How often must I charge the batteries?
Many factors come into play when deciding how often to charge the batteries. You may use your Pride LX all day
on a daily basis or you may not use it for weeks at a time. If you use your Pride LX on a daily basis, charge the
batteries as soon as you are finished using it for the day. Each morning, your Pride LX will be ready to give you a
full day’s service. We recommend that you charge the batteries for 8 to 14 hours after daily use. Do not charge the
batteries for more than 24 hours. If you use your Pride LX infrequently (once a week or less), you should charge the
batteries at least once per week for 12 to 14 hours.
NOTE: Keep the batteries fully charged and avoid deeply discharging the batteries. Do not charge them for more
than 24 hours at one charge.
How can I get maximum range or distance per charge?
Rarely will you have an ideal driving situation, such as smooth, flat, hard terrain with no hills or curves. More
often, you will encounter hills, sidewalk cracks, uneven and loosely packed surfaces, and curves. 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 fully charge the batteries prior to your trip.
n Plan your trip in advance to avoid inclines if possible.
n Limit the baggage weight to essential items.
What type of battery should I use?
We recommend deep-cycle batteries that are sealed and maintenance free. Both AGM and Gel-Cell are deep-cycle
batteries and are similar in performance.
Use these specifications to reorder deep-cycle batteries:

Type:
Size:
Voltage:
Amp Hours:
Deep-cycle (AGM or Gel-Cell)

WARNING! Corrosive chemicals contained in batteries. Use only AGM or Gel-Cell batteries to reduce the
risk of leakage or explosive conditions.
26
www.pridemobility.com
Pride LX Series/Rev B/Feb 03
VI I I . BATTERIES AND CHARGING
Why do my new batteries seem weak?
Deep-cycle batteries employ a 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, and
then accept a relatively quick recharge. Lead-acid batteries should be charged as often as possible. They do not
have a “memory” like nickel-cadmium batteries.
We work closely with our battery manufacturer to provide batteries that best suit the Pride LX’s specific demands.
Fresh batteries arrive regularly and are promptly shipped with a full charge. During shipping, the batteries encounter
temperature extremes that may influence their initial performance. Heat will rob the charge from the battery, and
cold will slow the power available and extend the time needed to recharge the battery (just as with a car battery).
It may take a few days for the temperature of a battery to stabilize and adjust to its new ambient temperature. More
importantly, it will take a few “charging cycles” (partial draining followed by full recharging) to establish the
critical chemical balance that is essential to a battery’s peak performance and long life.
It will be well worth it for you to take the time to break-in the batteries 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?
A fully charged deep-cycle battery will provide reliable performance and extended life. So, keep the 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 Pride LX operation and limited battery life.
How should I store my Pride LX and batteries?
If you do not use your Pride LX regularly, we recommend maintaining battery vitality by charging the batteries at
least once per week.
If you do not plan on using your Pride LX for an extended period of time, fully charge the batteries prior to storage.
Disconnect the battery harnesses and store the Pride LX in a warm, dry environment. Avoid temperature extremes,
such as freezing or excessively hot conditions, and never attempt to charge a frozen battery. A cold or frozen
battery should be warmed for several days prior to recharging.
NOTE: If you are storing your Pride LX for an extended period of time, you may wish to block the unit up off the
ground or floor with several boards placed under the frame. This will keep the tires off the ground and prevent the
possibility of flat spots developing where the tires rest on the ground or floor.
What about public transportation?
Sealed lead-acid and gel cell batteries are designed for application in power chairs and other mobility vehicles. We
suggest you contact the commercial carrier’s ticket counter in advance to determine the carrier’s specific
requirements.

Figure 28. Dynamic DL-50 Controller
Joystick
The joystick controls the direction and speed of your power chair. When you move the joystick from the netural
(center) position, the electromagnetic brakes release and allow your power chair to move. The further 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.
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.
On/Off Key
This is an on/off key located in front of the joystick which turns the DL-50 on and off.
WARNING! Unless faced with an emergency situation, do not use the on/off push button to stop the chair.
This will cause the power chair to stop abruptly.
WARNING! Always turn the power off when you are stationary to prevent unexpected movement.
Battery Condition Meter
The battery condition meter is located behind the joystick. This is a six-segment, three-color illuminated display
that indicates if the DL50 is turned on and also gives the battery status, the DL-50 status, and the electrical system
status. All six red lights lit represents a full state-of-charge and a single red light lit represents lowest state-ofcharge. A low state-of-charge warning is represented by the left-most light flashing on and off.
NOTE: Check your battery condition meter regularly and charge the batteries before they are completely discharged.
Speed Control
Sets the maximum speed of the power chair: clockwise to increase, counterclockwise to decrease.
NOTE: We recommend that the first few times you operate your power chair, you turn the speed control to the
slowest setting until you become familiar with your new power chair.

OPERATION
Off-board Charger/Programming Socket
Your DL-50 may have a 3-pin socket on the front which enables you to use an off-board battery charger. The socket
may also be used for reprogramming the controller by using a programmer, should this be necessary. Contact your
authorized Pride provider for more information.
Horn
Activates the horn.
9-pin Connector
This connects the DL-50 controller to the power chair’s batteries, motors, and motor brakes.
3-pin Charger Inhibit Connector
This connects the DL-50 to the onboard battery charger. This connection provides the DL-50 with an inhibit that
disables it when the battery charger is on. During charging, the battery condition meter will flash briefly to indicate
that the inhibit is active. The charger inhibit connector is coded with colored dots. The dots are positioned so that
you align the flat side of the male connector with the flat side of the female connector before making the connection.
CAUTION! Failure to properly align the connectors can result in damage to the controller, the charger
harness, and the connectors.
Joystick Out Of Neutral At Power Up
Your power chair joystick is equipped with Out Of Neutral At Power Up (OONAPU). If you power up the system
and the joystick is not in the neutral (center) position, the battery gauge flashes rapidly in 2.5-second intervals. The
battery gauge will flash as long as the joystick is out of the neutral position. If the joystick remains out of the
neutral position for four seconds or more, then the battery gauge will display a fault. If this happens, then return the
joystick to the neutral position and power off the DL-50. The next time you power on the DL-50, the code should
be cleared.
NOTE: If this condition persists, contact your authorized Pride provider.
Thermal Rollback
The DL-50 electronic controller features a thermal rollback circuit. This circuit monitors the temperature of the
motors, the power module, and the master remote. In the event these components become excessively hot (above
122° F), the power module reduces the motor voltage. For every degree above 122° F, the power module reduces
the voltage by 5 volts. This reduces your speed and allows the components to cool down. When the temperature
returns to a safe level, your power chair will resume its normal speed.
Troubleshooting
In addition to indicating battery charge, the lights also provide diagnostic information when the DL-50 detects
problems with either the electrical system, or the DL-50 itself. These codes are displayed when all lights flash the
number of times given by the fault code. The following table identifies the individual fault codes. If you get one of
these codes, contact your authorized Pride provider.

In addition to indicating the current state of battery charge, the battery condition meter can also indicate possible
problems with your power chair. The battery condition meter has ten lights. The lights provide information by the
number of lights that are flashing. If any of the meter lights are flashing rapidly, the controller may be indicating a
fault. For instance, if the first light is flashing rapidly, the battery voltage is nearly depleted. The following is a list
of the possible errors signified by the rapidly flashing meter. When you get a trouble code, contact your authorized
Pride provider.

CARE
AND
MAINTENANCE
CARE AND MAINTENANCE
Your power chair is a sophisticated, motorized vehicle. Like any motorized vehicle, it requires routine maintenance
checks. You can perform some of these checks yourself. But other maintenance checks may require assistance
from an authorized Pride provider. Routine maintenance is very important. If you follow the routine 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 authorized Pride provider.
General Guidelines
n Avoid knocking or bumping the controller, especially the joystick.
n Avoid prolonged exposure of your power chair to extreme conditions, such as heat, cold, or moisture.
n Keep the controller clean.
n When the battery condition meter is completely lit, the batteries are fully charged, and the controller and the
electrical system are OK.
n If one red light on the battery condition meter is blinking slowly, the batteries are low and need to be charged,
but the controller and the electrical system are OK.
n If the battery condition meter or system status light is blinking rapidly, the controller has detected a fault in
either its own circuits or in your power chair’s circuits. See IX. “Operation.”
n Make sure the drive tires are inflated to 30 – 35 psi.
WARNING! Make sure your tires are inflated to 30-35 psi. Do not underinflate or overinflate your
tires. Low pressure may result in loss of control, and overinflated tires may burst. Serious
personal injury may result. Overinflatingtires can cause them to explode and can result in personal
injury.
WARNING! Do not use a high pressure hose to inflate your tires.
n Use a rubber conditioner on the tire sidewalls to help preserve them.
WARNING! Never use a rubber conditioner on the tread area of the tires; doing so may make the
tires slippery and cause your power chair to skid.
n Check all electrical connections. Make sure they are tight and are not corroded. Batteries must sit flat within
the battery well, with the battery terminals facing inward, toward each other. Refer to the battery wiring
label for the correct wiring layout. See figure 32.
n All wheel bearings are prelubricated and sealed. They require no subsequent lubrication.
Daily Checks
n With the controller turned off, check the joystick. Make sure it is not bent or damaged and that it returns to the
neutral position when you release it.
n Check the rubber boot around the base of the joystick for damage.
n Visually inspect the boot. Do not handle or try to repair it. See your authorized Pride provider if there is a
problem.
n Visually inspect the controller harness. Make sure that it is not frayed, cut, or has any wires exposed. See your
authorized Pride provider if there is a problem with any harnesses.
Weekly Checks
n Disconnect and inspect the controller from the electronics tray. Look for corrosion. Contact your authorized
Pride provider if necessary.

CARE
AND
MAINTENANCE
n Ensure that all parts of the controller system are securely fastened to your power chair. Do not overtighten any
screws.
n Check for proper tire inflation. There should be 30 – 35 psi in each pneumatic tire. If a tire does not hold air, see
an authorized Pride provider for replacement.
n Calibrate the joystick if you detect a noticeable difference in performance or if the joystick does not operate
properly. To calibrate the joystick, power off the unit, place the joystick in the neutral position, and power the
unit back on. If a problem still exists with your joystick’s performance, contact your authorized Pride
provider.
n Check the brakes. This test should be carried out on a level surface with at least three feet of clearance around
your power chair.
To check the brakes:
1. Turn on the controller and turn down the speed of your power chair to the lowest setting.
2. After one second, check the battery condition meter. Make sure that it remains on.
3. Slowly push the joystick forward until you hear the electric brakes click. Immediately release the joystick. You
must be able to hear each electrical brake operating within a few seconds of joystick movement. Repeat this
test three times, pushing the joystick backwards, then left, and then right.
Monthly Checks
n Check for extreme wear on the anti-tip wheels. Replace them as necessary.
n Check for drive tire wear. See an authorized Pride provider for repair.
n Check the casters for wear. Replace them as necessary.
n Check the rear forks for damage or fluttering which indicates that they may need to be adjusted or have the
bearings replaced. See an authorized Pride provider for repair.
n Keep your power chair clean and free of foreign material, such as mud, dirt, hair, food, and drink, etc.
Yearly Checks
Take your power chair to an authorized Pride provider for yearly maintenance. This helps ensure that your power
chair is functioning properly and helps prevent future complications.
Storage
Your power chair should be stored in a dry place, free from temperature extremes. When storing, disconnect the
batteries from the power chair. See VIII. “Batteries and Charging.”
WARNING! If you fail to store the unit properly, the frame can rust and the electronics can be
damaged.

CARE
AND
MAINTENANCE
Cleaning Precautions
CAUTION! Never hose off your Pride LX or place it in direct contact with water. Your LX has a
painted, ABS plastic body shroud that allows it to be easily wiped clean with a damp cloth.
CAUTION! Never use any chemicals to clean a vinyl seat, as they may cause the seat to become
slippery or dry out and crack. Use soapy water and dry the seat thoroughly.
CAUTION! 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 dry 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 you find any inconsistencies, take your power chair to an authorized Pride provider.
Temperature
Some of the parts of your power chair are susceptible to extreme changes in temperature. Always keep your power
chair between the temperatures of 18° F and 122° F.
n In extremely cold temperatures, the batteries may freeze. The specific temperature at which they freeze depends
on a number of factors, such as battery charge, usage, and composition of the batteries (e.g., sealed lead-acid or
gel cell).
n Temperatures above 122° F may cause your power chair to operate at a reduced speed. This reduced speed is a
safety feature built into the controller that helps prevent damage to the motor and other electrical components.
See IX. “Operation.”
Tires
You should check your tires at least once per week. This will
prolong the life of your tires as well as help ensure the perfect
operation of your chair. Look for cuts in your tires or uneven
wear. If you have solid tires, you must replace the whole wheel.
If you have pneumatic tires, you can replace the tire or the tube.
Replacement parts are readily available at your authorized Pride
provider.
17-MM DRIVE WHEEL NUT AND WASHER
WARNING! To avoid possible injury, be sure that the
controller’s power is turned off and the power chair
is not in freewheel mode before performing this
procedure.

Motor Brushes
The electric motors that power your power chair use carbon brushes. These brushes may become susceptible to
wear over a long period of time. The motor brushes are the two contacts located inside the motor assembly that
supply power to the motor. They are designed to provide several thousand hours of operation. However, if the
brushes become dirty with carbon deposits or wear out, the motor will run poorly or not at all.
CAUTION! If inspection determines excessive wear
on the brushes, they must be replaced or motor damage will result. Failure to maintain the brushes could
void your power chair’s warranty.
To inspect or replace the motor brushes:
1. Unscrew the motor brush caps. See figure 30.
2. Remove the brushes.
3. Inspect for wear. See figure 34.
4. Replace brushes, if necessary. Contact your authorized Pride
provider for replacement brushes.

Corrective Maintenance
If the battery condition meter does not light up when you turn on the power:
n Check the harness connections. Make sure they are tight.
n Check the circuit breaker. Reset it if necessary.
n Check the battery connections.
If the above conditions prove normal, you can load test the batteries with a battery load tester. These testers are
available at automotive parts stores. Disconnect both batteries before load testing and follow the directions that
come with the load tester. If either one of the batteries fails the load test, replace both of them. If your power chair
still does not power up, contact your authorized Pride provider.
