PaceSaver Scout Boss, Boss 6NS & Boss 6.75 OWNERS MANUAL
Introduction
Congratulations on your choice of a power wheelchair! It is a dependable vehicle built for power and performance. Its easy to operate controls give
you more of what you are looking for in a wheelchair.
But it is important that you understand what your power wheelchair is,
and what it is not. Our power wheelchairs (like all power wheelchairs) ar e designed
to provide safe, reliable transportation to older or moderately physically disabled
individuals who have diffi culty in getting around. It will safely take you everywhere
the specifi cations indicate as long as you follow the simple safety guidelines shown
on the next few pages.
The power wheelchair is not an all terrain vehicle that you can use out in
the fi elds to drag brush around or climb steep hills. It was not meant to go hunting
in, or transport you thru hazardous environments. It also was not designed for the
severely handicapped individual who should not be in a power wheelchair. You must
have good stability , motor contr ol and above all else, good common sense to use our
wheelchair , or any other brand. If you feel that you cannot safely operate this vehicle
at all times, you should not use this power wheelchair!
Important
Please read the entire manual carefully before attempting to drive your
new power wheelchair.

Please use common sense, courtesy, and obey the following guidelines for vehicle
operation.
READ THIS ENTIRE MANUAL
BEFORE DRIVING THIS VEHICLE.
Safety Guidelines
Always turn the power switch to the OFF position when stopped or when getting off or
on the power wheelchair. This keeps you from accidentally hitting the throttle and
causing an accident. For persons with limited lower body strength, or persons who
make slide transfers and may forget to turn the power switch off, we recommend

Keep your feet on the footrests while riding the power wheelchair to avoid hitting
them on objects as you drive. Always wear shoes while operating your power
wheelchair.
Always wear your lap belt when riding your power wheelchair.
Secure the removable seat assembly before operating the power wheelchair to
prevent yourself from falling from the seat while moving.
Remember, The power wheelchair is built to carry a single person. Do not carry
passengers under any circumstances or accidents and bodily injury will occur.
Ensure driving surface, ramp, platform lift or elevator is capable of supporting
combined weight of user and wheelchair.

Use caution when driving off even a small curb or raised surface. The act of dropping of f
the edge subjects the power wheelchair to extreme forces that can damage the frame
and other components. This type of damage is not covered under warranty.
Disconnect the batteries before performing any maintenance or if you will not be riding
the power wheelchair for more than a few days. This avoids both the possibility of
injuries due to shock and helps lengthen the battery life. Make sure that the batteries
are secure when you are using the power wheelchair.

Follow the directions of your doctor and/or pharmacist at all times. Do not drive the
power wheelchair while taking medications that affect your refl exes or judgment,
as your driving will be impaired and accidents may result. Do not drink alcohol
or use any other stimulants while operating this or any other vehicle.
The following are important things to help you drive the power wheelchair in the
safest possible manner. Please take note of each and every one.
WARNING DO NOT engage in the following activities with your power wheelchair or
serious personal injury may result.
DO NOT ride the power wheelchair with the brake disengaged at anytime.
DO NOT drive the power wheelchair diagonally across inclines, turn sharp on an incline or
make turns at or near full throttle at any time. Doing this will result in the power wheelchair
losing traction and control which can result in tipping and possibly serious injuries.
DO NOT drive the power wheelchair with the seat assembly higher than necessary as tip-
ping and serious injury may result. The lower the seat, the better your stability.
DO NOT drive the power wheelchair with under-infl ated tires as this increases the possibil-
ity of tipping and injury. Your stability and effi ciency (power and range) are also greatly
affected.
DO NOT remain seated on your power wheelchair while it is being loaded into a vehicle
using anything other than a special wheelchair lift, or personal injury may result.
DO NOT
ride on soft, uneven surfaces as this can cause lose of traction and control causing
tipping and that may result in serious injury.
DO NOT
stop on any incline to rest or dismount. Although the electric brake will stop and
hold you, it is best to stop in level, fl at areas where there is no possibility of rolling, or tipping
the unit or having the occupant fall out.
DO NOT ride your power wheelchair without wearing your lap belt at all times or
serious injury may result. This is especially important on ramps or inclines.

DO NOT drive up, down or across inclines greater than the rating for your style power
wheelchair or tipping will result. Refer to the Specifi cation Sheet (Please Note:
Soft surfaces reduce the incline capability by more than 50%). Wet or slick surfaces
reduce steering and braking controls tremendously. Use extreme caution in these
circumstances.
DO NOT travel down ramps at high speed. Doing so will reduce traction and increase
stopping distance.
DO NOT allow the power wheelchair controls to become wet. Never wash off the
power wheelchair using a hose or a stream of water, drive through standing water or
ride in the rain. Possible loss of control and/or electronic damage will occur. Do not
attempt to ride a power wheelchair that has been soaked until it has had a chance to dry
thoroughly.
DO NOT leave the power wheelchair where it is exposed to high temperatures
(a car trunk, etc.) or to poor weather conditions such as rain or snow or freezing
conditions as damage to the unit will occur.
DO NOT disassemble any wheel at any time while still infl ated. The pressure may
blow wheel rims apart while you are loosening them.
DO NOT ride the unit near platforms, stairs, ledges, curbs or in any other potentially
dangerous situation as serious injury can result.
DO NOT ride the power wheelchair over power cords, oxygen lines, hoses or any other
material that could become entangled in the wheels or get caught in the drive mechanism
of the power wheelchair or while connected to equipment off of the power wheelchair.
DO NOT attempt to reach objects if you have to move forward in the seat.
DO NOT attempt to reach objects if you have to pick them up from the fl oor by reaching
down between your knees.

ELECTRICAL
EXTREME care should be exercised when using oxygen in close proximity to electric circuits. Contact your oxygen supplier for instruction in the use of oxygen.
Grounding instructions:
DO NOT, under any circumstances, cut or remove the round grounding prong from any plug
used with or for Leisure-Lift products. Some devices are equipped with three-prong (grounding) plus for protection against possible shock hazards. Where a two-prong wall receptacle
is encountered, it is the personal responsibility and obligation of the customer to contact a
qualifi ed electrician and have the two-prong receptacle replaced with a properly grounded
three-prong wall receptacle in accordance with the National Electrical Code. If you must use
an extension cord, use ONLY a three-wire extension cord having the same or higher electrical rating as the device being connected. In addition, Leisure-Lift has placed RED/ORANGE
WARNING TAGS on some equipment. DO NOT remove these tags. Carefully read battery/
battery charger information prior to installing, servicing or operating your wheelchair.
RAIN & MOISTURE
LEISURE-LIFT has established the following rules for dealing with moisture.
End user or their attendant should allow suffi cient time to remove his/her power wheelchair
prior to a rain storm or inclement weather to retain wheelchair operation.
DO NOT leave your power wheelchair in a rain storm of any kind.
DO NOT use your power wheelchair in a shower or leave it in a damp bathroom while
taking a shower.
DO NOT leave your power wheelchair in a damp area for any length of time.
Direct exposure to rain or dampness will cause the wheelchair to malfunction electrically and
mechanically; may cause the wheelchair to prematurely rust.
Check to ensure that the batteries are secured in place, the joystick boot is NOT torn or
cracked where water can enter and that all electrical connections are secure at all times.
DO NOT use the joystick if the boot is torn or cracked. If the joystick boot becomes torn or
cracked, replace IMMEDIATELY.

SAFETY/HANDLING OF POWER WHEELCHAIRS
“Safety and Handling” of the wheelchair requires the close attention of the wheelchair user as
well as the assistant. This manual points out the most common procedures and techniques involved in the safe operation and maintenance of the wheelchair. It is important to practice and
master these safe techniques until you are comfortable in maneuvering around the frequently
encountered architectural barriers.
Use this information only as a “basic” guide. The techniques that are discussed on the following pages have been used successfully my many.
Individual wheelchair users often develop skills to deal with daily living activities that may
differ from those described in this manual. Leisure-Lift recognized and encourages each individual to try what works best for him/her in overcoming architectural obstacles that they may
encounter. Techniques in this manual are a starting point for new wheelchair users and assistants with “safety” as the most important consideration for all.
ST ABILITY AND BALANCE
WARNING
Always wear your lap belt.
To assure stability and proper operation of your wheelchair, you must at all times maintain
proper balance. Your wheelchair has been designed to remain upright and stable during normal daily activities as long as you do not move beyond the center of gravity.
The anti-tip wheels are normally positioned approximately two inches off the ground (with a
rider in the chair) but may be adjusted in height downward by your dealer . Because your
wheelchair is a "midi" (3/4) drive chair the anti-tip wheels are normally only used when brak-
ing going forward down a steep incline. Reducing this setting causes the powerchair to tilt
forward at a lesser angle before resting on the anti-tip wheels if you decelerate rapidly while
going down a hill. The normal adjustment should allow the
inch obstacle.
DO NOT lean forward out of the wheelchair any further than the length of the armrests.

STAIRWAYS - WARNING
DO NOT attempt to move an occupied power wheelchair between fl oors using a stairway or
escalator. Use an elevator to move an occupied power wheelchair between fl oors. If moving a
power wheelchair between fl oors by means of a stairway, the occupant MUST be removed and
transported independently of the power wheelchair Again, DO NOT use an escalator to move
a wheelchair between fl oors. Serious bodily injury may occur..
Extreme caution is advised when it is necessary to move an UNOCCUPIED power wheelchair
up or down the stairs. Leisure-Lift recommends disassembling your wheelchair into smaller,
more manageable components to keep from personal injury. Lifting by means of any removable (detachable) parts of a wheelchair may result in injury to the user or damage to the wheelchair.
Follow this procedure for moving wheelchair between fl oors when an elevator is NOT available:
ESCALATORS - WARNING
DO NOT use an escalator to move a wheelchair between fl oors. Serious bodily injury may occur.
TRANSFERRING TO/FROM OTHER SEATS
WARNING
ALWAYS turn the wheelchair power OFF and engage the motor locks/clutches to prevent the
wheels from moving BEFORE attempting to transfer in or out of the wheelchair. Also make
sure every precaution is taken to reduce the gap distance. Always have an attendant or healthcare professional present while learning to properly transfer yourself.
CAUTION
When transferring, position yourself as far back as possible in the seat. This will prevent
damaging the upholstery and the possibility of the wheelchair tipping forward. See section
Getting On and Off the Power Wheelchair.
PERCENTAGE OF WEIGHT DISTRIBUTION
WARNING
DO NOT attempt to reach objects if you have to move forward in the seat or pick them up
from the fl oor by reaching down between your knees.
Many activities require the wheelchair user to reach, bend and transfer in and out of the
wheelchair. These movements will cause a change to normal balance, center of gravity, and
weight distribution of the wheelchair. To determine and establish your particular safety limits,
practice bending, reaching and transferring activities in several combinations in the presence
of a qualifi ed health professional BEFORE attempting active use of the wheelchair. Remem-
ber. . . Keep your lap belt on at all times.
Never roll backward down an incline as caster rotation reduces rearward stability.
11
Page 12
REACHING, LEANING, BENDING AND BENDING - FORWARD
Position the rear casters so that they are extended as far rearward as possible and engage motor locks/clutches. DO NOT LEAN FORWARD OF THE ARMRESTS.
REACHING, BENDING - BACKWARDS
WARNING
DO NOT lean over the top of the back upholstery. This will change your center of gravity and
may cause you to tip over.
Position wheelchair as close as possible to the desired object. Point rear casters rearward to
create the longest possible wheelbase. Reach back only as far as your arm will extend without
changing your sitting position.
Persons having disabilities which limit their ability to remain erect without assistance,
(stroke patients, severe muscular diseases, etc.) should carefully evaluate whether they
should operate a wheelchair at all. If they decide, with the advise of their physician or another advisor, that they are capable of safely operating a wheelchair, they should consider
the use of a bicycle helmet or pads when operating a wheelchair. These articles would help
protect them should they fi nd themselves in a hazardous situation where they could tip over
or fall because of their lack of balance.
DIFFERENT STYLES OF POWER WHEELCHAIRS HAVE DIFFERENT INCLINE CLIMBING ABILITIES. CAREFULL Y STUDY THE CHAR T TO SEE THE CORRECT SPECIFICATIONS FOR YOUR UNIT. DO NOT EXCEED THE SPECIFICATIONS OF THE POWER

Getting On and Off The Power Wheelchair
The following is a recommended method for getting on your Power Wheelchair
1. The wheelchair should be stopped on a fl at, level surface with the power switch in the OFF posi-
tion (no visible lights).
2. Raise the foot rest plate so that you may back up to the wheelchair squarely. WARNING: Do not use the
footplate as a platform. When getting in or out of the wheelchair make sure that the footplates are in the upward position or swing footrest towards the outside of the wheelchair.
We realize that many bariatric persons can not do a side transfer or raise their legs to raise and lower the footplate. If and only if you must step on the footplate for entering or exiting the power wheelchair, you must follow these instructions. Your power wheelchair is equipped with a patented infi nitely adjustable rigid anti-tip
system (see fi gure 1 under Battery Removal Section). When both of the front anti-tip wheels are lowered to
contact the fl oor, you can step on the platform without tipping the chair forward. After entry the wheels must
be raised to adjust to the driving environment - 1/4” for fl at fl oors and up to 2” for outdoor terrain. Always
keep the adjustment as low as possible for your driving area. Warning: Failure to lower the anti-tip wheels
for entry and exit will result in the chair tipping forward when you stand on the footplate which can cause you
to fall and result in possible serious injury. Warning: As with any wheelchair part should the anti-tip assembly become damaged, discontinue use immediately and contact your dealer for service. Warning: Always
keep anti-tip wheels at the same height from fl oor to prevent tipping to side.
(SEE WARNING BELOW)
3. Position yourself squarely in front of the seat and lower yourself into the seat using the armrests if necessary. (Never use the control housing or joystick as a support while getting on and off the wheelchair.)
4. Lower the footrest and place your feet securely on the footrest.
5. Buckle the safety belt around yourself belt to help hold yourself securely in the chair.
6. Push the power button on the speed control, the LED lights should activate.
7. When seated comfortably, you can drive the power wheelchair.
The method for getting off is the reverse procedure.
1. Turn the power switch OFF when stopped (no visible lights).
2. Unfasten your safety belt and raise (or have someone raise) the footrest bracket.
3. Make sure your feet are planted fi rmly on the ground and stand up.
WARNING
Keep the power button in the OFF position at all times when stopped or when getting on or off the wheelchair. Sudden accidental movement of the wheelchair will be avoided with the power switch in the OFF
position.
Tipping can occur if you get on the power wheelchair in a manner other than recommended. Tipping can be
avoided by keeping your weight away from the outer edges until seated. If you step into the wheelchair, sit
directly in the center of the seat, not near the edge. Tipping, loss of control or traction (wheel spin) can also occur
if you turn the joystick sharply while traveling at or near full throttle and on slick surfaces or inclines.

Operating the Power Wheelchair
Controls for the power wheelchair operation are located on the arm mounted joystick console and
the power module mounted to the frame. Become familiar with all controls with the power button
in the OFF position. Each is described in the following section
1. On/Off
2. Increase/Decrease Speed
3. Battery Gauge
4. Joystick
5. Horn
6. Speedometer
7. Attendant Control LED
8. Service Indicator LED
Joystick Console
1. TURNING THE POWER ON Press the Power button. All indicators will fl ash briefl y. The
current state of battery charge will be displayed and the powerchair may be operated as normal.
Note: If the SHARK is turned on while the joystick is out of neutral, an OONAPU fault will be dis-
played - refer to the SHARK Display Information Chart.. Release the joystick back to neutral and
the fault will disappear.
OONAPU (Out Of Neutral At Power Up) is a featur e that prevents SHARK for driving if the joystick
is out of neutral when SHARK is turned on or an inhibit condition removed.
This feature prevents sudden and unexpected powerchair movements.
1.1 TURNING THE POWER OFF Press the Power button. The LED's will turn off.
Note: Alternatively, SHARK may be placed into a Lock Mode (See Locking Instructions). This may
be preferable to turning the power off if leaving the power chair at a place where unauthorized persons may attempt to use the powerchair.
2. ADJUSTING THE DRIVING SPEED The user can adjust the chair's top speed to suit their preferences and environment.
The currently selected top speed is shown on the Speedometer and
can be adjusted using the "Increase Speed" (Hare) and "Decrease
Speed" (Tortoise) buttons.

the Increase Speed (Decrease Speed) Button
ramps the top Speed up (down) in fi ne steps,
allowing practically any top speed to be selected. This can be particularly useful for matching
the chair speed to the walking speed of an accompanying pedestrian.
VSP is an extremely powerful feature, allowing both fast stepping between fi xed top speeds
by using quick presses or fi ner control using long presses. The VSP feature can be enabled or
disabled. Users can toggle between the "VSP" and "5 Speed" Modes by holding down both the
Increase Speed and Decrease Speed Buttons for approximately 2 seconds while the unit is powered up. The control unit will beep when the mode has been changed.
2.1. USING THE SPEEDOMETER The Speedometer is used to gauge the
relative speed of the chair in comparison to the maximum speed possible. The right-most LED
indicates current maximum speed, which can be adjusted using
the Increase (Decrease) Speed button. Refer to Adjusting the
Driving Speed for further details. Using the joystick, as the speed
of the chair increases, the LED's will fi ll in until the maximum
speed (as displayed) is reached.

3. BATTERY INDICATOR. The SHARK Information Gauge (located on the joystick
console) is the primary source of user feedback. It displays every possible status that SHARK
may have.
True state-of-battery-charge, including notifi cation of when the battery desperately requires
charging.
• Any green LED's lit indicates well-charged batteries.
• If only amber and red LED's are lit, the batteries are moderately charged.
Recharge before undertaking a long trip.
• If only red LED's are lit the batteries are running out of charge. Recharge as soon
as possible.
4. THROTTLE CONTROL JOYSTICK LEVER. The joystick mounted on the top
of the control panel is both the throttle and direction control lever (Push Slowly). Pushing the
joystick with your thumb in the direction of the horn button on the control faceplate will make
the wheelchair go forward or backward accordingly . Pushing the joystick in slightly will makes
the wheelchair begin to move. The further you depress the joystick, the faster the wheelchair
moves. The top speed set by the Tortoise/Hare buttons is reached by fully depressing the joystick. Completely releasing the joystick will stop power to the motor, activate the brakes, and
you will come to a complete stop. For faster stops in forward, pull the joystick into reverse until
the unit stops moving, then release the joystick.
5. HORN BUTTON
Your unit also comes
PLEASE NOTE:
equipped with a built in horn, activated by depressing the horn button.
Should the joystick / brake control system not stop the unit, turning the power
switch off will engage all brakes and stop the unit abruptly. This backup system should only
be used in the unlikely event that the primary brake control is disabled, as the quick stop could
CAUSE YOU TO SLIDE OFF THE WHEELCHAIR. Remember to wear your lap belt.

6. LOCKING THE SHARK Most SHARKs are supplied with a factory programmed
LOCK Feature that prevents unauthorized people from turning the SHARK on.
TO LOCK:
While the power is ON, press and hold the Power button for 4 seconds.
The horn will sound a short beep and all LED's will fl ash briefl y. The
powerchair will then turn off.
TO UNLOCK:
While the SHARK is locked, press the Power button to turn the SHARK
on. All LED's will fl ash briefl y. The LED's will then perform a right-
to-left "chase". Press the Horn button twice before the timer completes
its pass (approximately 10 seconds). The current state-of-charge will
then be displayed and SHARK may be operated normally.
Note: If the user does not press the Horn button twice within the time
limit, the Horn will sound a short beep and SHARK will turn itself off. The unlock sequence must
be completed successfully before the SHARK will drive again normally.

METHODS FOR CONTROLLING THE DIRECTION OF YOUR
POWER WHEELCHAIR.
Pushing the joystick
straight forward will
cause the wheelchair
to move in a forward
direction. Your speed
is determined by how
far forward you push
the Joystick and by
the speed
control setting (# 2).
Pulling back on the
joystick causes the wheelchair to move
in the reverse direction
The diffi cult part of controlling a power wheel-
chair is all of those moves in between the four
main directions. Shown here are different direc-

tions for turning the wheelchair as you operate
the vehicle, but remember these moves may be
anywhere in between, it depends on the direction of travel required at the time. The important thing to remember is that in the forward
positions, the joystick is like a pointer, point and
that is the direction you will go. In reverse, the
pointer is indicating the direction the front of the

wheelchair will go, not the back. The best thing
to do is learn to operate your power wheelchair
in a large fl at open space, and practice making
the chair move in the direction you desire.
Moving the joystick directly to the left (while
stationary or moving) will
cause the chair to turn to the
left. Conversely , moving to
the right will cause it to turn
right. If you are stationary ,
the chair will tend to rotate
where it sits. You may use
this to position your self in
place, or to prepare to travel
in a different direction.

In an emergency or a "Quick-Stop" situation, you may pull straight back
on the joystick momentarily to cause the motors to apply reverse current
and stop quickly. Use extreme caution, as this may cause your body to
pitch forward in the chair. Always wear your lap belt.

For your fi rst ride, we recommend the following.
When possible, always work with your dealer or therapist to learn how to use your power wheelchair.
Different chairs have different adjustable features such as spring suspension, programmable controllers,
front anti-tips, footrest height & angle, length adjustments and arm adjustments etc.
Work with your dealer to make sure the wheelchair is specifi cally fi tted to YOUR needs.
1. Make sure the area is a fl at, hard, smooth, open and free of obstacles.
2.
Make sure your lap belt is securely fastened and the seat is securely locked.
3. Depress the power switch to turn the power switch to ON.
4. Adjust the SPEED setting display (Speedometer) to low.
5. Push the control knob forward to go forward.
6. Steer the chair in different directions to get a feel for how the controls operate.
7. SLOWLY increase the Max. SPEED indicator on the speedometer by holding the button
down with the "Hare" symbol on it until the desired top speed is reached. Remember,
power compensation will automatically gives you more power and allows you to keep a
slower speed should you need it. Refer to Adjusting the Driving Speed Instructions.
8. Release the joystick to come to a stop. Take note of how the braking
feels. The clicking you might hear upon starting, and shortly after releasing the
joystick is the Electric Brake disengaging and engaging.
9. Push the joystick backwards to thumb to go backward. There is a signifi cant reduction
in speed in the reverse direction without any change in the Max. SPEED setting. Always
make sure the area is clear behind you before backing up.
10. Remember to turn the power button OFF (no visible lights) when not driving, or
getting on or off the wheelchair.
Speed controller characteristics are pre-set for the average rider. The anti-tip wheels are normally
positioned approximately 1/2" off the ground (with a rider in the chair) but may be adjusted in height.
Because your power wheelchair is a "midi" (3/4) drive chair the anti-tip wheels are normally only
used when braking going forward down a steep incline. Reducing this setting causes the powerchair
to tilt forward at a lesser angle before resting on the anti-tip wheels if you decelerate rapidly while
going down a hill. See specifi cation page for maximum obstacle climbing capability.
Warning
The power wheelchair is designed for high maneuverability but use caution when encountering
obstacles. Failure to drive cautiously can result in tipping and/or collisions which may cause physical
harm. When approaching an obstacle, keep your speed at a minimum and maintain a safe distance
from that object. Avoid all small objects on the ground. The wheelchair's ground clearance may be
less than the size of the object. Running over an object or into a depression could cause overturning,
or damage to the wheelchair. NEVER ride the unit near platforms, stairs, ledges, curbs or in any other
potentially dangerous situation as severe injury can occur.

The Power Wheelchair Braking Systems
The power wheelchair's brake systems allow for smooth start up and safe braking without
undue jerking. There are three (3) separate modes to the braking system: Regenerative, Dynamic, and Posi-Lock Electric Braking. All braking occurs automatically during wheelchair
operation if the joystick power is "ON". If the joystick power is turned "OFF", the regenerative
braking and dynamic braking are not functional. WARNING: Always leave the joystick power
"ON" when parked on or attempting to stop on an incline. Failure to leave the joystick power
"ON" could result in partial loss of braking and steering control causing potential damage to
the equipment and/or harm to the rider. Each type of braking is described in the following.
1. Regenerative Braking is activated while driving the power wheelchair down an
incline. When the wheelchair picks up speed going down the incline, the motor
generates electricity. This electricity is channeled back through the power wheelchair
electronic control circuits to recharge the batteries. This action keeps the wheelchair
from picking up excess speed and provides for smooth speed control.
2. Dynamic Braking is activated WITHOUT delay when all power is stopped to the
motor by bringing the control knob back to the center position, as when coming to a
complete stop. This braking works until the Posi-Lock Electric brake is activated.
3. Posi-Lock Electric Braking Disk is activated with delay when all power is stopped to
the motor. This electric brake has a short delay and ultimately holds the power
wheelchair at a complete stop. The wheelchair cannot be moved when this brake is
activated. Dynamic Braking works in conjunction with Posi-Lock Electric Braking
to bring you to a gradual and complete stop.
MOTOR/BRAKE DISENGAGE MECHANISM
The power wheelchair is equipped with one Motor/Brake
Disengage lever (one for the entire motor). This systems allows
the wheelchair to be moved in the event the batteries are run
low , or there is a malfunction. T o operate the Motor disengage
mechanism, turn the power off to the wheelchair and push the
lever completely backwards. The motor/brake combination is
now disengaged and the wheelchair will not operate, but will
roll freely.
Caution:
DO NOT ride the power wheelchair with Motor/Brake Disengage Mechanism activated
since there is a
any type of brake system malfunction, DO NOT ride or sit on the wheelchair . Have the system
repaired immediately!

strong possibility an accident with injuries will occur. Should you experience
21
Page 22
Seat Assembly Operation
The power wheelchair comes with removable/height adjustable arms. These arms are designed to
provide support for your arms while seated on the wheelchair, and for assistance when getting on and
off of the wheelchair. Each arm is designed to hold 300 pounds, and NOT THE PERSONS
TOTAL BODY WEIGHT. Persons with no use of their legs, or no ability to transfer weight to
the fl oor should seek other means of assistance (slide board, helper, etc.) when transferring in
and out of the wheelchair. Arm failure will result if excess weight is applied to the arm.
Width adjustable arm adjustments
1. Loosen the black knobs under the edge of the seat. Rotate counter clockwise to loosen.
2. Slide the armrests in or out as needed.
3. Tighten the black knobs. Rotate clockwise to tighten.
Should you wish to remove the armrests, simply pull them out when the knobs are loose. Re-
member to tighten the knobs to avoid their loss.
Seat Height Adjustment
The seat assembly is height adjustable.
1. Remove the seat assembly by unpinning the seat and lifting the seat assembly
straight up. Set aside.
2. Locate the seat height adjustment bolts and nut located on the post where pins were removed.
3. Remove the bolt, nut, and washers. Take note of their position in order to correctly re
place them.
4. The seat height post will now move up and
down.
5. Position the seat height to new desired position.
6. Replace the washers, bolt, and nut in their
proper order. Tighten until all play is
eliminated.
7. Replace the seat assembly and test the new
height.
It is recommended that the seat assembly be positioned
at the lowest comfortable seat height. The power wheelchair's stability will be improved with a lower height.

cable to the controller.
Follow the entry instructions elsewhere in this manual, and go for a ride.
CHARGING THE POWER WHEELCHAIR BATTERIES
Charging the batteries is the most important part of operating and maintaining your new wheelchair . Be sure
you do it properly! As per international standards, it is recommended that only gel cell or sealed suspended
lead-acid type deep cycle batteries be used on the wheelchair. These batteries should meet FAA (Federal
Aviation Administration) guidelines and be marked as non-spillable or spill proof.
Y our wheelchair comes with a fully automatic, 24 volt constant current of f-board charger . Which provides a
constant charging output until the batteries are fully charged and can be left “on charge” inde fi nitely without
harm to the batteries.
Please refer to the instructions packaged with your charger for additional information, including its
specifi c LED charging status indicators.
NOTE: Some chargers have a small cooling fan located inside the charger which is thermostatically controlled
and may come on when the internal temperatures exceed the design limits. This may or may not operate at
regular intervals. Do not rely on its operation as an indication of charger output.

Battery Charging
The satisfactory performance of the SHARK system is critically dependent on the type and state of the batteries. The battery charger used must be correctly selected and adjusted according to the battery manufacturer’s
instructions. Failure to do so may damage or destroy the batteries, give poor range, or be potentially dangerous. Batteries should not be abused (for example by deep discharging or overcharging) and must be operated
and maintained according to the manufacturer’s instructions.
The battery charger socket is a 3 pin XLR type with pin confi guration as shown below. Ensure that the
charger used is compatible with this pin out before connection. The safety link between B- and the Inhibit
pin must be fi tted so that the wheelchair is prevented from driving when the batteries are being charged.
Warning : Do not disconnect batteries or open circuit the circuit breaker during charging. This is dangerous to both people and equipment.

!! CAUTION !!: Be certain the wall cord is disconnected from the electrical outlet before moving the
wheelchair. Moving the wheelchair without disconnecting the wall cord could result in damage to the
wheelchair, the wall outlet or create a shock hazard condition.
++WARNING++: Because you will be connecting and disconnecting AC to the wheelchair, be cautious
of doing so in the presence of water (i.e., rain or puddled water). Electrical shock hazard could be present. Observe caution and safety warnings.
++WARNING++: Lead-acid batteries generate gasses which can be explosive. Avoid smoking, sparks
or open fl ames around charging batteries. Charge in area with adequate ventilation.
++WARNING++: Char gers can ignite fl ammable materials and gasses. Do not use near fuels, grain dust,
solvents, thinners or other fl ammable materials. Charge in area with adequate ventilation.
Charging Notes:
Regular use of your chair will require regular charging. It is a common misconception that batteries need
to be run into deep discharge before recharging. This is not true and can lead to damage of the batteries if
they are discharged too deeply before recharge. Likewise, if batteries are stored or used for a long period
of time without recharge, this may result in permanent damage to the batteries resulting in unreliable
operation and shortened battery life. Maximum driving range of your wheelchair can be obtained if the
batteries are fully charged prior to a lengthy trip. Because the charger is a fully automatic charger, it
can be "on charge" for an indefi nite period of time without harm to the batteries.
Fuse:
There are no replaceable fuses in the charger. This charger uses solid state technology to protect the
unit and the batteries until the fault has been removed.
Service/ Troubleshooting: Should your charger fail to perform:
1. First, check that all connections are properly made for a fully assembled wheelchair. On some
equipment, the charger lines go through the motor plug, so if the motor plug is disconnected for some
reason, then the charger will not function. Likewise, if the batteries are not connected, they will not
receive a charge, and the meter will not give an indication.
2. Check that the wall outlet has power to it. The outlet may be on a switch and will not function if
not switched on.
If these steps fail to produce satisfactory results, please refer to an authorized service center to have the
system fully analyzed.

Useful Battery Information
1. The battery indicator in the control panel takes into account time as well as battery
voltage to provide a more accurate estimate of battery capacity while you are driving. The
display simulates a bar graph where all LED's lit represent a full state of charge and a single
red LED represents the lowest state of charge. If, while you are driving, the indicator falls
into the red area, charge the batteries as soon as possible. Charging will bring deep cycle
condition batteries up to full charge. You will not see maximum battery life if the batteries
are routinely run to the deep cycle condition.
2. It is best to charge the batteries before they reach the deep cycle condition. Short
charge intervals to keep a battery “topped off” are better than long intervals for bringing a
battery up from deep cycle. The charger can be left on overnight or for several days at a time,
but once the batteries are fully charged, it is best to unplug the charger.
3. Keep the batteries away from heat. Areas with excessive sunshine or excessive
heat will cause a faster loss of charge in the batteries. Charging the batteries longer than
necessary will also introduce heat into them. Heat will cause the batteries to lose their charge
and also shorten their life.
4 Storage of batteries is very important to their life span. The very best way to maximize battery life is to store them in a fully charged condition in a cool place. Then, periodically
charge EVERY ONE TO TWO MONTHS to keep the batteries in this fully charged
condition. Batteries should never be subjected to freezing temperatures. Undercharged
batteries can be quickly ruined in freezing conditions.
5. Loose connections can keep the batteries from delivering their power. V isually check
the battery wire connections in the battery box periodically for looseness. Always connect
the red wire to the positive (+) battery terminal. Connect the black wire to the negative (-)
battery terminal.
WARNING: Do not use a non sealed liquid lead acid deep cycle battery. Spillage of
battery acid will cause severe burns, and will corrode metal components of the power wheelchair.

Storage of the Power Wheelchair
Short Term and Overnight Storage
When ending power wheelchair's use for the day, if the batteries do not need char ging, simply
turn the power OFF. The next morning, get in, lock the seat, activate the key, turn power ON
and you are ready to go again. In areas with public access, use of the key function will restrict
powered operation of your power wheelchair.
Long Term Storage
When the power wheelchair will not be used for an extended period of time, there are
several things you should do to help maintain its proper working condition.
The powerchair and its batteries should only be stored in a dry environment with
moderate temperatures. Long term exposure to excessive hot or cold temperatures will be
harmful to the life of the batteries. The batteries must be fully charged before they are stored.
We also recommend that you disconnect the battery leads or remove the batteries from the
powerbase.
Every one to two months, you should reconnect the battery leads and the charger to make
sure that the batteries are still fully charged.
Maintaining the Power Wheelchair
In general, The power wheelchair is very easy to maintain. Consult your dealer if any
repairs, adjustments, or damaged part replacements are needed.
Routine Maintenance
Daily
- Charge the batteries, if required, as described in the “Charging the

chair. The components that SHARK provides fault information for include, the motor, the park brakes, the
batteries, the cabling and the SHARK modules themselves.
Note that joystick OONAPU (Out OF Neutral At Power Up) is not a fault. Simply by removing your hand
from the joystick and allowing it to return to the neutral position, the fault will immediately clear.
The nature of the abnormal condition is indicated by a fl ash code. This is a sequence of fl ashes, separated
by a pause, followed by a repetition of the sequence. The number of fl ashes relates to the condition. For
instance, four fl ashes of the SHARK information gauge, a pause, followed by four fl ashes, etc. indicates a
right motor fault. Five fl ashes would indicate a left park brake fault.
Depending on the severity of the condition, the powerchair may or may not allow driving. In some cases
the chair may be allowed to drive but in a reduced speed ("limp") mode.
DIAGNOSTICS & FAULTS
Flash codes indicate the nature of an abnormal condition directly from the
SHARK Information Gauge. Without the use of any servicing tools, the condition
can be simply diagnosed.

Commonly Asked Questions and Possible Answers
Why has there been a sudden loss of power?
1. Undercharged batteries. Check the BATTER Y indicator . The BATTER Y indicator
indicates the charge condition of the batteries while you are driving. The indicator
will not indicate the “true condition” of their capacity until the wheelchair has been
setting on, in an idle condition, for several minutes. The green area corresponds to a
good charge. The red area corresponds to a low char ge, or a deep cycle condition.
It is possible to drive the wheelchair with the batteries in a deep cycle charge condition, but once they drop below a certain level of power, they will fail and you will be
stranded. If, while you are driving, the indicator falls into the red area, charge the
batteries as soon as possible. Charging will bring deep cycle condition batteries up
to full charge. You will not receive maximum battery life if the batteries are routinely
run to the deep cycle condition.
2. Under-infl ated tires. Check for proper infl ation (check the specifi cations for your
particular wheelchair).
3. Excessive weight on the wheelchair . Refer to the specifi cation chart for the maxi-
mum rider weight.
4. There may be other motor or driving mechanism malfunctions. Consult with your
dealer.
Will leaving the batteries for a long time damage them?
Yes. Storage of batteries is very important to their life span. The very best way to
maximize battery life is to store them in a fully charged condition in a cool place. Then periodically ( every 1-2 months!) charge to keep the batteries in this full charge condition. Do
not store in cold or freezing temperatures. Batteries should never be subjected to freezing
temperatures. Undercharged batteries can be ruined quickly in freezing conditions.

Can a regular liquid lead-acid battery be used, like in a car?
No! A DEEP CYCLE battery must be used. A car battery is not deep cycle. Deep
cycle batteries (boat type batteries) are available in both suspended liquid lead-acid and gel
cell lead-acid. Either type can be used. It is recommended that a gel cell or a sealed leadacid type battery be used on the power wheelchair. These batteries are maintenance free
and have no danger of spillage. They are also approved by the Federal Aviation Administration for air travel. Do not use a conventional liquid lead-acid deep cycle battery. Spillage of the battery acid can cause severe burns and will damage many components of your
power wheelchair. The charger which came with the power wheelchair is designed specifi -
cally to charge deep cycle batteries.
Why will my Power Wheelchair not climb an incline?
1. Excessive weight on the wheelchair for the grade of the incline. Refer to the Ramp Incline
Chart in this Owner’s Manual.
2. Batteries not fully charged, or are bad. Charge them and have them tested.
3. Under-infl ated tires.
4. Attempting to go up the incline in reverse. Remember, there is a signifi cant reduction in
speed when moving in the reverse direction.
Again, thank you for your purchase of a power wheelchair. We hope that
you will enjoy many years of trouble free service and freedom on your
new wheelchair. Remember, your investment and your safety depend
upon following the guidelines and suggestions contained in this manual.

ELECTROMAGNETIC INTERFERENCE
CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE
POSSIBLE EFFECTS OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED
WHEELCHAIR.
Electromagnetic Interference (EMI) From Radio Wave Sources
Powered wheelchairs and motorized scooters (in this text, both will be referred to as powered wheelchairs)
may be susceptible to electromagnetic interference (EMI), which is interfering to electromagnetic energy
(EM) emitted from sources such as radio stations, TV stations, amateur radio (HAM) transmitters, two-way
radios, and cellular phones. The interference (from radio wave sources) can cause the powered wheelchair
to release its brakes, move by itself, or move in unintended directions. It can also permanently damage the
powered wheelchair's control system. The intensity of the interfering EM energy can be measured in volts
per meter (v/m). Each powered wheelchair can resist EMI up to a certain intensity. This is called its "immunity level." The higher the immunity level, the greater the protection. At this time, current technology is
capable of achieving at least a 20 v/m immunity level, which would provide useful protection from the more
common sources of radiated EMI.
There are a number of sources of relatively intense electromagnetic fi elds in the everyday environment.
Some of these sources are obvious and easy to avoid. Others are not apparent and exposure is unavoidable.
However, we believe that by following the warnings listed below, your risk to EMI will be minimized.
The sources of radiated EMI can be broadly classifi ed into three types:
1) Hand-held portable transceivers (transmitters-receivers) with the antenna mounted directly
on the transmitting unit. Examples include: citizens band (CB) radios, "walkie talkie," sec urity, fi re, and police transceivers, cellular telephones, and other personal communication
devices. **NOTE: Some cellular telephones and similar devices transmit signals while they
are ON, even while not being used;
2) Medium-range mobile transceivers, such as those used in police cars, fi re trucks, ambulances,
and taxis. These usually have the antenna mounted on the outside of the vehicle; and
3) Long-range transmitters and transceivers, such as commercial broadcast transmitters (radio
and TV broadcast antenna towers) and amateur (HAM) radios.
NOTE: Other types of hand-held devices, such as cordless phones, laptop computers, AM/FM radios, TV
sets, CD players, and cassette players, and small appliances, such as electric shavers and hair dryers, so far
as we know, are not likely to cause EMI problems to your powered wheelchair.
38

Powered Wheelchair Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna (source),
the EM fi elds from hand-held radio wave sources (transceivers are of special concern). It is possible to un-
intentionally bring high levels of EM energy very close to the powered wheelchair's control system while
using these devices. This can affect powered wheelchair movement and braking. Therefore, the warnings
listed below are recommended to prevent possible interference with the control system of the powered
wheelchair.
WARNINGS
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM)
transmitters, two-way radios, and cellular phones can affect powered wheelchairs and motorized scooters.
Following the warnings listed below should reduce the chance of unintended brake release or powered
wheelchair movement which could result in serious injury.
1) Do not operate hand-held transceivers (transmitters-receivers), such as citizens band (CB)
radios, or turn ON personal communications devices, such as cellular phones, while the powered
wheel-chair is turned ON;
2) Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming close to
them;
3) If unintended movement or brake release occurs, turn the powered wheelchair OFF as soon as it
is safe;
4) Be aware that adding accessories or components, or modifying the powered wheelchair, may
make it more susceptible to EMI (Note: There is no easy way to evaluate their effect on the
overall immunity of the powered wheelchair); and
5) Report all incidents of unintended movement or brake release to the powered wheelchair
manufacturer, and note whether there is a source of EMI nearby.
Important Information
1) 20 volts per meter (v/m) is a generally achievable and useful immunity level against EMI
(as of May 1994) (the higher the level, the greater the protection).
2) This model of PaceSaver scooter has an immunity level of 20 volts per
meter (20 v/m).
The immunity level of this model of PaceSaver is unknown.
