OPERATION OF MECHANISM
GENERAL
WARNING If you fail to heed these warnings, a fall or tip over may occur and
cause severe injury to you:
1. Start off slowly. If you are not familiar with the maneuverability of this wheelchair you may
loose control and tip over.
2. Have someone help you until you know what can cause a tip over and how to avoid doing
so. Never try a new maneuver on your own until you are sure you can do it safely.
3. Your chair is most stable when you are moving forward. Be very careful when you move
your wheelchair backward. You may lose control or tip over if one of the rear wheels hits an
object and stops rolling.
CENTER OF BALANCE
WARNINGS The point where the chair will tip forward, rearward or to the side
depends on its center of balance and stability. If you fail to heed
these warnings, a fall or tip over may occur and cause severe
injury to you.
1. To avoid a fall or tip over, you should have someone help you until you know the balance
points of your chair and how to avoid a tip over.
2. The center of balance and stability of your chair are affected by :
A. A shift in your body position, posture or weight distribution.
B. Riding your chair on a sloped surface.
CURBS AND SINGLE STEPS
WARNINGS If you fail to heed these warnings, a fall or tip over may occur and
cause severe injury to you or others:
1. The anti-tip devices are not removable and may interfere.
2. Do not try to climb or descend a curb or a step, more than 1 1/2 inches high. Whenever
possible, seek a suitable ramp or access designed for electric wheelchairs.
CAUTION The impact from dropping down from a curb or step can damage
the frame or other chair parts and may loosen fasteners. Check for
damage to the wheelchair or loose fasteners before each use.

9
DOORWAYS AND OBSTACLES
1. Make sure that the floor area where you use this chair is level and free of obstacles. You
may need to:
A. Remove or cover threshold strips between doors.
B. Install a ramp at some doors.
2. To help correct the center of balance of your wheelchair you should:
A. Lean your upper body forward slightly as you go up over an obstacle.
B. Press your upper body backward as you go down from a higher to a lower level.
ESCALATORS
WARNING Never take a chair on an escalator, even with an attendant. Doing
so is likely to cause a fall or tip over and severe injury to you and
others.
MOTOR VEHICLE SAFETY
WARNING Wheelchairs of Kansas wheelchairs do not meet the federal
standards for motor vehicle seating. If you fail to heed these
warnings, the rider may suffer a severe injury:
1. Never permit anyone to sit in this wheelchair while he or she is in a moving vehicle. The
rider may be thrown from the chair in an accident or sudden stop. Wheelchair positioning
belts will not prevent this.
2. Always move the rider to an approved vehicle seat. Secure the rider with proper motor
vehicle restraints.
3. Never transport this chair in the front seat of a vehicle. It may shift and interfere with the
driver. Always secure this chair so that it cannot roll or shift.
REACHING OR LEANING
(Example: Dressing or Changing Clothes)
WARNINGS Reaching or leaning affects the center of balance of your
wheelchair. If you fail to heed these warnings, a fall or tip over may
occur and cause severe injury to you:
OPERATION OF MECHANISM

10
OPERATION OF MECHANISM
1. Avoid reaching or leaning if you must shift your weight to do so. Ask for help or use a
device to extend your reach.
2. Never try to reach an object if you must move forward in your seat to do so. This may
cause the wheelchair to tip forward. Always keep your buttocks in contact with the
backrest.
3. Never reach with both hands. If you do so, you may not be able
to catch yourself to prevent a fall if the chair tips.
4. Never lean backward to reach an object.
5. If you must reach or lean from your chair:
A. Place your chair as close as you can to the object you wish to
reach.
B. Avoid putting pressure on the footrests/elevating legrests
while you reach. This may cause the chair to tip forward.
WARNINGS
2. Avoid turning on a slope, as a tip over is likely. Always go as straight up and straight down
as you can.
3. The power drive mechanism WAS NOT designed to climb a slope and/or incline greater
than 10 degrees. (A 10% slope means: One foot of elevation for every ten feet in length of
the slope.) Ask for help if the slope is greater than 10 degrees.
4. Controlling speed when going downhill:
A. The power drive mechanism was designed to maintain a safe speed while going down a
10 degree or less slope. Ask for help if the slope is greater than 10 degrees.
B. Never use the rear wheel locks to try to slow or stop your wheelchair. Doing so is likely
to cause you to veer out of control or tip over.
SLOPES
Going up or down a slope will change the center of balance of your
chair. If you fail to heed these warnings, you may suffer a severe
injury from a tip over, fall or lose of control:
1. Lean or press your body uphill to help correct the change in the center of balance.

OPERATION OF MECHANISM
STREETS AND ROADWAYS
WARNINGS In most states, wheelchairs are not legal for use on public roads. Be
alert to the dangers of motor vehicle traffic on roads or in parking
lots.
1. At night, or when lighting is poor, use reflective tape on your wheelchair and clothing to
make it easier for drivers to see you.
2. Due to low position, it may be hard for drivers to see you. Make eye contact with drivers
before you go forward. When in doubt, yield until you are sure it is safe.
TRANSFERS
WARNINGS If you fail to heed these warnings, a fall or tip over may occur and
cause severe injury to you:
1. Transfers require good balance and agility and are very dangerous. Be aware that there is
a point during each transfer when the chair seat is not below you.
2. Always lock the rear wheels before you transfer.
3. Locking the rear wheels will not keep your chair from sliding away from you or tipping. To
avoid a fall, you should:
A. Learn how to position your body and how to support yourself during a transfer.
B. Work with your doctor, nurse or therapist to learn safe transfer methods.
C. Have someone help you until you are sure you can perform
safe transfers on your own.
4. Rotate the front casters into position show to make the chair
more stable.
5. Be careful of the footrests. To avoid a trip or fall when you
transfer, you should:
A. Make sure your feet do not “hang up” or get caught in the
space between the footrests.
B. Avoid putting weight on the footrests as the chair may tip
forwards.
C. If you can, remove or swing the footrests out of the way.
6. Removing armrest may be helpful.

OPERATION OF MECHANISM
TRANSPORTING A CHAIR AND RIDER UP OR DOWN STAIRS
WARNING Wheelchairs of Kansas does not endorse or recommend the lifting
of the chair, with a person in it. Other means of transport must be
used to carry a person over stairs or obstructions in the pathway if
no ramp or other means is provided to properly roll the chair
around or over the stairs or obstructions.

ANTI-TIP DEVICE
WARNING The anti-tip devices are not designed to bear the weight of the
wheelchair and rider. Failure to heed this warning when climbing or
descending stairs, curbs, steps or other objects could result in
damage to the wheelchair and cause the wheelchair to tip or fall
causing severe injury to you or others.
ARMREST
The armrests are detachable. They are not designed to bear the weight of the wheelchair.
WARNING Never try to lift the wheelchair by its armrest. They may come loose
or break. If this occurs, the wheelchair may fall and cause severe
injury to you or others. Lift the wheelchair only by non-detachable
parts of the main frame.
BATTERIES
Never tamper with the batteries on this wheelchair.
WARNING The type of batteries used on this wheelchair contain a highly
corrosive acid. Never let the acid come in contact with yourself or
any other object. If you fail to heed these warnings, you may suffer
severe burns or other injury and/or cause damage to anything that
comes into contact with the acid.
If the batteries become damaged, contact your authorized
Wheelchairs of Kansas dealer immediately for replacement. Always
read and follow battery manufacturer’s directions.
Your PEV Powerchair could have either Gel batteries (sealed) or Lead Acid. You and your
dealer, once having assessed your intended use of the powerchair, should make this choice.
The primary difference between the two types are, lead acid holds approximately 20% more
charge so they can go longer between charges. Lead acid can also be recharged in twice the
time of a sealed battery. Lead acid batteries require periodic maintenance. If tipped over they
can leak acid and need special handling if being transported by an airline.
Do not rely on the battery charger to tell whether or not the batteries are fully charged. Do not
rely on the voltage indicator on the joystick to tell whether or not the batteries have been fully
charged, or if the batteries can maintain a charge. Periodic inspection needs to be done with
the proper test equipment and trained service personnel. It is normal for batteries to gradually
wear down and require longer charging times. See maintenance section for additional care
instructions of battery.

FEATURES
CHARGING THE BATTERY:
Connect the charger to the bottom side of the joystick, then
connect to the wall outlet. Always connect the charger to the
powerchair first, then connect to the wall outlet.
Always keep your powerchair fully charged. Connect the
batteries to a charger every night and then disconnect them in
the morning. A charging pattern of 12 to 14 hours on a charger
and 12 to 14 hours off a charger will help to maintain strong fully
charged batteries.
When charging Gel or sealed batteries, do not exceed a 8-amp charge rate. Doing so runs the
risk of irreversible damage to the battery by causing it to split open or burst. The proper
charger is shipped with the powerchair.
When charging lead acid batteries do not exceed a 12-amp charge rate. Doing so runs the risk
of prematurely wearing out the batteries.
When charging is complete, disconnect the charger from the wall outlet first, then from the
powerchair. Always disconnect the charger from the wall outlet first, then from the powerchair.

splitting. Check visually only, do not handle the gaiter.
Mounting: Make sure the controller is securely fixed to your wheelchair. Do not over tighten
any screws.
Precautions For Use
The VR2 control system has been designed with the user’s safety as the prime consideration.
It incorporates many sophisticated self-test features which search for potential problems at a
cycle of 100 times per second. If the control system detects a problem either in its own circuits,
or in the wheelchair’s electrical system, it may decide to halt the wheelchair depending on the
severity of the problem. The VR2 is designed to maximize the user’s safety under all normal
conditions.
In spite of its sophistication, the VR2 cannot take into account circumstances which put the
wheelchair and/or the controller outside of their specified operation conditions, and so it is
important that the user follows the precautions below:
1. Do not drive the wheelchair:
A. Beyond restrictions indicated in the wheelchair user manual, for example maximum
inclines, curb height etc.
