WHEELCHAIR USER
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of
wheelchairs to meet many needs of the end user. However, final selection of the
type of wheelchair to be used by an individual rests solely with the user and his/her
healthcare professional capable of making such a selection.
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS
Wheelchair users should not be transported in vehicles of any kind while in
wheelchairs. As of this date, the Department of Transportation has not approved
any tie-down systems for transportation of a user while in a wheelchair, in a moving
vehicle of any type.
It is Invacare’s position that users of wheelchairs should be transferred into
appropriate seating in vehicles for transportation and use be made of the restraints
made available by the auto industry. Invacare cannot and does not recommend any
wheelchair transportation systems.
ꢀ WARNING
The seat positioning strap is a positioning belt only. It is not designed for use as a
safety device withstanding high stress loads such as auto or aircraft safety belts. If
signs of wear appear, the belt MUST be replaced immediately.
Invacare products are specifically designed and manufactured for use in conjunction
with Invacare accessories. Accessories designed by other manufacturers have not
been tested by Invacare and are not recommended for use with Invacare products.
The drive behavior initially experienced by the user may be different from other
chairs previously used. This power wheelchair has Invacare’s SureStep technology, a
feature that provides the chair with optimum traction and stability when driving
forward over transitions and thresholds of up to 1-inch.

SECTION 1—GENERAL GUIDELINES
Batteries
The warranty and performance specifications contained in this manual are based on the
use of deep cycle gel cell batteries. Invacare strongly recommends their use as the power
source for this unit.
Carefully read battery/battery charger information prior to installing, servicing or
operating your wheelchair.
The use of rubber gloves is recommended when working with batteries.
Some battery manufacturers mold a carrying strap and/or hold down flanges directly into
the battery case. Batteries that interfere with the battery box cannot be used for these
applications. Attempting to “wedge” a battery into a battery box may damage the box, the
battery and/or be a fire hazard, resulting in serious injury or further damage to property.
Charging Batteries
ꢁ DANGER
When using an extension cord, use only a three wire extension cord having at least
16 AWG (American Wire Gauge) wire and the same or higher electrical rating as
the devise being connected. Use of improper extension cord could result in a risk of
fire and electric shock. Three prong to two prong adapters should not be used. Use
of three prong adapters can result in improper grounding and present a shock
hazard to the user.
NEVER attempt to recharge the batteries by attaching cables directly to the battery terminals.
DO NOT attempt to recharge the batteries and operate the wheelchair at the same time.
DO NOT operate wheelchair with extension cord attached to the AC cable.
DO NOT attempt to recharge the batteries when the wheelchair has been exposed to any
type of moisture.
DO NOT attempt to recharge the batteries when the wheelchair is outside.

DO NOT, under any circumstances, cut or remove the round grounding prong from any
plug used with or for Invacare products. Some devices are equipped with three‐prong
(grounding) plugs for protection against possible shock hazards and fire. Where a two‐
prong wall receptacle is encountered, it is the personal responsibility and obligation of the
customer to contact a qualified 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,
Invacare has placed RED/ORANGE warning tags on some equipment. DO NOT remove
these tags.
Rain Test
Invacare has tested its power wheelchairs in accordance with ISO 7176 “Rain Test.” This
provides the end user or his/her assistant sufficient time to remove his/her power
wheelchair from a rain storm and retain wheelchair operation.
DO NOT leave power wheelchair in a rain storm of any kind.

SECTION 2—EMI INFORMATION
SECTION 2—EMI INFORMATION
ꢀ WARNING
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 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 fields 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 classified 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", security, fire and police transceivers, cellular telephones,
and other personal communication devices).
NOTE: Some cellular telephones and similar devices transmit signals while they are ON,
even when not being used.
2) Medium-range mobile transceivers, such as those used in police cars, fire 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, cassette players, and small appliances, such as elec-
tric shavers and hair dryers, so far as we know, are not likely to cause EMI problems to
your powered wheelchair.

SECTION 2—EMI INFORMATION
ꢀ WARNING
Powered Wheelchair Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense as one moves closer to the
transmitting antenna (source), the EM fields from hand-held radio wave sources
(transceivers) are of special concern. It is possible to unintentionally 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.
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 communication devices, such as cellular
phones, while the powered wheelchair 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 device has been tested to a radiated immunity level of 20 volts per meter;
3) The immunity level of the product is unknown.
Modification of any kind to the electronics of this wheelchair as manufactured by
Invacare may adversely affect the EMI immunity levels.

SECTION 4—SAFETY/HANDLING OF WHEELCHAIRS
SECTION 4—SAFETY/HANDLING OF
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 by many.
Individual wheelchair users often develop skills to deal with daily living activities that
may differ from those described in this manual. Invacare recognizes and encourages each
individual to try what works best for him/her in overcoming architectural obstacles that
they may encounter, however all warnings and cautions given in this manual MUST be
followed. Techniques in this manual are a starting point for the new wheelchair user and
assistant with “safety” as the most important consideration for all.
Stability and Balance
ꢀ WARNING
ALWAYS wear your seat positioning strap. The seat positioning strap is a
positioning belt only. It is not designed for use as a safety device withstanding high
stress loads such as auto or aircraft safety belts. If signs of wear appear, belt MUST
be replaced immediately.
DO NOT attempt to reach objects if you have to move forward in the seat or pick
them up from the floor by reaching down between your knees.
Proper positioning is essential for your safety. When reaching, leaning, bending or
bending forward, it is important to use the casters as a tool to maintain stability and
balance.
Many activities require the wheelchair user to reach, bend and transfer in and out of
the wheelchair. These movements will cause a change to the 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 qualified healthcare
professional before attempting active use of the wheelchair.
Be aware that carrying heavy objects on your lap while occupying the wheelchair
may adversely affect the stability of the wheelchair, resulting in serious bodily injury
to the user, damage to the wheelchair and surrounding property.
This wheelchair has been designed to accommodate one individual. If more than
one individual occupies the wheelchair this may adversely affect the stability of the
wheelchair, resulting in serious bodily injury to the user and passenger and damage
to the wheelchair and surrounding property.

SECTION 4—SAFETY/HANDLING OF WHEELCHAIRS
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. DO NOT lean forward out of the wheelchair any further than the length of the
armrests.
Coping With Everyday Obstacles
NOTE: For this information, refer to FIGURE 4.1.
Coping with the irritation of everyday obstacles can be alleviated somewhat by learning
how to manage your wheelchair. Keep in mind your center of gravity to maintain stability
and balance.
While the walking beam allows you to traverse up to a 1‐inch bump or threshold,
stopping after the wheels cross the bump poses a problem. The chair cannot reverse over
the bump at this point. Continue forward and then turn around.
While the wheelchair is designed for use
primarily in and around the home, the
provider should determine whether this
chair is suitable for the actual environment
the chair will be used in.
1-inch Bump
or Threshold
DO NOT go down ramp at full speed.
Some seat/back positions will cause
wheelchair to feel unstable.
CAUTION
Be aware of condition of ramp. Traction will be diminished/nonexistent on a
slippery surface. Proceed with caution.
A Note to Wheelchair Assistants
When assistance to the wheelchair user is required, remember to use good body
mechanics. Keep your back straight and bend your knees whenever tilting wheelchair or
traversing curbs or other impediments.
Also, be aware of detachable parts such as arms or legrests. These must NEVER be used
to move the wheelchair or as lifting supports, as they may be inadvertently released,
resulting in possible injury to the user and/or assistant(s).
When learning a new assistance technique, have an experienced assistant help you before
attempting it alone.

ꢀ WARNING
DO NOT attempt to move an occupied power wheelchair between floors using a
stairway. Use an elevator to move an occupied power wheelchair between floors. If
moving a power wheelchair between floors by means of a stairway, the occupant
MUST be removed and transported independently of the power wheelchair.
Extreme caution is advised when it is necessary to move an unoccupied power
wheelchair up or down the stairs. Invacare recommends using two assistants and
making thorough preparations.
Use only secure, nondetachable parts for hand-hold supports.
It is strongly recommended to lift the wheelchair only by the rear frame and the
front forks - otherwise injury or damage may occur.
DO NOT attempt to lift the wheelchair by any removable (detachable) parts.
Lifting by means of any removable (detachable) parts of a wheelchair may result in
injury to the user or damage to the wheelchair.
The weight of the wheelchair with batteries and without the user is approximately
125 lbs. Use proper lifting techniques (lift with your legs) to avoid injury.
NOTE: For this procedure, refer to FIGURE 4.3 on page 21.

Transferring To and From Other Seats
ꢀ WARNING
ALWAYS turn the wheelchair power Off and engage the Motor Release Levers 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 by
aligning both the front and rear casters parallel with the object you are transferring
onto.
CAUTION
When transferring, position yourself as far back as possible in the seat. This will pre-
vent broken screws, damaged upholstery and the possibility of the wheelchair tip-
ping forward.
NOTE: For this procedure, refer to FIGURE 4.4 on page 22.
NOTE: This activity may be performed
independently provided you have adequate
mobility and upper body strength.

SECTION 6—WHEELCHAIR OPERATION
Using the Joystick to Drive the Wheelchair
NOTE: For this procedure, refer to FIGURE 6.2.
The joystick is located at the front of the joystick housing and provides smooth control of
speed and direction. It is equipped with 360 degrees of mobility for ease of operation. The
joystick is spring‐loaded, and automatically returns to the upright (neutral) position
when released. Pushing the joystick in a given direction causes the wheelchair to move in
that direction.
The joystick has proportional drive control, meaning that the further it is pushed from the
upright (neutral) position, the faster the wheelchair moves. The maximum speed,
however, is limited by the speed control setting.
To slow the wheelchair to a stop, simply release the joystick. The wheelchair has
automatic speed and direction compensation to minimize corrections.
When first learning to drive, select a slow speed and try to drive the wheelchair as slowly
as possible by pushing the joystick slightly forward. This exercise will help you learn to
utilize the full potential of the proportional control and allow you to start and stop
smoothly.
To drive the wheelchair, perform the following:

63
Download from Www.Somanuals.com. All Manuals Search And Download.
SECTION 13—BATTERIES
CAUTION
New batteries MUST be fully charged prior to initial use of the wheelchair.
ALWAYS charge new batteries before initial use or battery life will be reduced.
As a general rule, you should recharge your batteries as frequently as possible to
assure the longest possible life and to minimize required charging time. Plan to
recharge them when you do not anticipate using the wheelchair.
Basic concepts which will help you understand this automatic process are:
The amount of electrical current drawn within a given time to charge a battery is called
“charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate is
high. As a charge builds up, the charge rate is reduced, and the battery charger rate
decreases to a “trickle charge”.
NOTE: If the batteries need to be charged more often or take longer to charge than normal, they
may need to be replaced. Contact a qualified technician.
NOTE: The batteries can be charged by plugging an independent battery charger into the port
located on the front of the joystick.
Battery Charger Operation
ꢀ WARNING
Read and carefully follow the manufacturer’s instructions for each charger (supplied
or purchased). If charging instructions are not supplied, consult a qualified
technician for proper procedures.
NEVER leave the charger unattended when the charger circuit breaker is tripping.
Use of improper extension cord could result in risk of fire and electric shock.
Read and carefully follow the individual instructions for each charger (supplied or
purchased). If charging instructions are not supplied, consult a qualified technician
for proper procedures.
