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. Invacare highly
recommends working with a certified rehab technology supplier and/or a member
of NRRTS or RESNA.
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS (TRRO OR
TRBKTS)
TRRO includes four factory-installed transport brackets and a wheelchair anchored
pelvic belt. TRRO has been crash-tested in accordance with ANSI/RESNA WC Vol 1
Section 19 Frontal Impact Test requirements for wheelchairs with a 168 lb crash
dummy, which corresponds to a person with a weight of 114 to 209 lbs.
TRBKTS includes four factory-installed wheelchair transport brackets. TRBKTS has
not been crash-tested in accordance with WC 19. Use these transport brackets only
to secure an unoccupied wheelchair during transport.
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.
Refer to Transport Ready Package on page 123 for more information about transporting the wheelchair.

3G Storm Series® Wheelchairs
SPECIAL NOTES
TRRO AND TRBKTS WARNINGS
Only use the transport brackets included with TRRO and TRBKTS for the purposes
described in this manual.
Battery support brackets MUST be installed at all times. Otherwise, the wheelchair
will not be WC/19 compliant. Refer to Installing/Removing Batteries Into/From
Battery Boxes on page 91.
WARNING
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 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.
Wheelchairs should be examined during maintenance for signs of corrosion (water
exposure, incontinence, etc.). Electrical components damaged by corrosion should
be replaced IMMEDIATELY.
Wheelchairs that are used by incontinent users and/or are frequently exposed to
water may require replacement of electrical components more frequently.
POWERED SEATING SYSTEM WARNING
This seating system has been custom designed and will be assembled to the
wheelchair base before delivery to the user. The information contained in this
manual is for maintaining and adjusting the seating system. There are very few
adjustments that can safely be made by the user. If there is a procedure or
adjustment that needs to be performed on the seating system that is not in this
manual, DO NOT perform that procedure. Have the seating system serviced by a
qualified technician.
RECLINER WARNINGS
TO HEALTHCARE PROFESSIONALS/ASSISTANTS:
Make sure the occupant of the wheelchair is properly positioned.
When returning the occupant of the wheelchair to the full upright position, more
body strength will be required for approximately the last twenty degrees of incline
(reverse recline). Make sure to use proper body mechanics (use your legs) or seek
assistance if necessary to avoid injury.

*NOTE: Weight limitation is total weight (user weight plus any additional items that the user may
require [back pack, etc.]). Example: If weight limitation of the wheelchair is 300 lbs and additional
items equal 25 lbs, subtract 25 lbs from 300 lbs. This means the maximum weight limitation of the
user is 275 lbs.
**NOTE: Values for range are calculated for maximum chair weight rating using largest batteries
applicable (GP24), per test procedures described in ANSI/RESNA WC/VOL2-1998 Section 4 and
meet federal reimbursement requirements for this product. While considered typical, they are
derived based on certain ideal conditions. Variances in battery condition, user weight, usage
pattern or overall terrain conditions will result in actual values for range that differ from these
stated values. Users should become accustomed to how their unique conditions impact their
individual results. Users should become familiar with the battery discharge indicator on the
joystick to determine the range of their wheelchair. Refer to When to Charge Batteries on page 98
for more information about the battery discharge indicator.

3G Storm Series® Wheelchairs
SECTION 1—GENERAL GUIDELINES
Inasmuch as wheel locks are an option on this wheelchair, (You may order with or
without wheel locks.) transfer to and from the wheelchair in the presence of a qualified
healthcare professional to determine individual safety limits. Invacare strongly
recommends ordering the wheel locks as an additional safeguard for the wheelchair user.
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.
DO NOT overtighten hardware attaching to the frame. This could cause damage to the
frame tubing.
ALWAYS keep hands and fingers clear of moving parts to avoid injury.
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.
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. Align both casters parallel
with the object you are transferring onto.
DO NOT use with a broken or missing joystick knob.
DO NOT use if joystick does not spring back to the neutral position or becomes sticky or
sluggish.
DO NOT use if joystick boot is torn or damaged.
ALWAYS check foam grips for looseness before using the wheelchair. If loose, contact a
qualified technician for instructions.
ALWAYS engage both wheel locks AND reduce the gap distance BEFORE transferring to
and from the wheelchair. Turn all casters parallel to the object you are transferring onto.
Anti-Tippers must be used at all times. When outdoors on wet, soft ground or on gravel
surfaces, anti-tippers may not provide the same level of protection against tip over. Extra
caution must be observed when traversing such surfaces.
Avoid storing or using the wheelchair near open flame or combustible products. Serious
injury or damage to property may result.
DO NOT engage or disengage the motor locks until the power is in the OFF position.

Part No 1134791
SECTION 1—GENERAL GUIDELINES
NEVER operate the wheelchair or elevate/lower the seat while in any tilted/reclined/back
angle position over 20° relative to the vertical position. If the drive lock-out does not stop
the wheelchair from operating or the seat from elevating/lowering in a tilt position over
20° relative to vertical, DO NOT operate the wheelchair or elevate/lower the seat. DO
NOT attempt to adjust the drive lock-out. Have the wheelchair serviced by a qualified
technician.
Use only TSS, TRSS, TRCM, and SAC actuator controls to activate the tilt/recline/elevate
functions*. DO NOT USE any other actuator controls. Such devices may result in excess
heating and cause damage to the actuator and associated wiring and could cause a fire,
death, physical injury or property damage. If such devices are used, Invacare shall not be
liable and the limited warranty is void.
*NOTE: Specific actuator controls are noted for each function or combination throughout this
manual.
DO NOT operate tilt seat around children.
ALWAYS keep hands and feet out from underneath tilt seat - otherwise serious injury
may result.
DO NOT tip the seating system/wheelchair without assistance.
DO NOT store items under seat.

entangled and damaged during normal operation of seating system.
2G Tarsys Equipped with Vent Tray Only - Reduced tilt/recline limits apply. See the
electronics manual listed in Reference Documents on page 2.
2G Tarsys Equipped with Power Legrests Only - NEVER allow items to become trapped
between the legrest assemblies, otherwise damage to the power legrest may occur.
Wheelchairs with Manual Recliners Only
NEVER operate the wheelchair while in any recline position over 105° relative to the seat
frame. If the limit switch does not stop the wheelchair from operating in a recline position
greater than 105° relative to the seat frame, DO NOT operate the wheelchair. Have the
limit switch adjusted by a qualified technician.
Both gas cylinders MUST be operational and adjusted properly before using the recliner.
DO NOT operate the recliner option if only one of the gas cylinders is operational or
adjusted properly.

SECTION 1—GENERAL GUIDELINES
Tire Pressure
DO NOT use your wheelchair unless it has the proper tire pressure (P.S.I.). DO NOT
overinflate the tires. Failure to follow these recommendations may cause the tire to
explode and cause bodily harm. The recommended tire pressure is listed on the side wall
of the tire.
Electrical
Grounding Instructions:
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. 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.
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.
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 device being connected. Use of improper extension cord could result in 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.
3G Storm Series® Wheelchairs

SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS
SECTION 2—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 climb, go UP or DOWN ramps or traverse slopes greater than 9°.
Invacare strongly recommends proceeding down ramps or slopes slowly to avoid
hard braking or sudden stops.
DO NOT leave elevating legrests in the fully extended position when proceeding
down ramps or slopes.
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.
Part No 1134791
33
3G Storm Series® Wheelchairs
SECTION 2—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. Make sure the casters are pointing in the forward position whenever you lean
forward. This can be achieved by advancing the wheelchair and then reversing it in a
straight line.
Coping with Everyday Obstacles
Coping with the irritation of everyday obstacles can be somewhat alleviated by learning
how to manage your wheelchair. Keep in mind your center of gravity to maintain stability
and balance.
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.
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 floor 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 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.
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.
When using the recliner/high back van seat, the motor/gearbox or motor MUST use
most REARWARD mounting holes on the suspension arm assembly.

SECTION 3—EMI INFORMATION
SECTION 3—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 electric shavers and hair dryers, so far as we know, are not likely to cause EMI problems to
your powered wheelchair.
3G Storm Series® Wheelchairs

Part No 1134791
SECTION 3—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) The immunity level of this product is unknown.
Modification of any kind to the electronics of this wheelchair as manufactured by
Invacare may adversely affect the RFI immunity levels.

SECTION 5—WHEELCHAIR OPERATION
Using the Joystick to Drive the Wheelchair
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 setting of the speed-control knob.
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 steps:
1. Perform one of the following:
• MKIV-A and MKIV-RII Joysticks - Adjust speed control knob to the appropriate
setting.
• MKIV-A+ Joysticks - Select the desired drive program.
2. Turn the power on. Refer to Turning the Power On/Off on page 49.
3. Maneuver the joystick in the following manner:
MOVEMENT
ACTION
Forward
Push forward on the joystick.
Reverse
Pull back on the joystick.
Turn Left
Move the joystick right.
Turn Right
Move the joystick left.

SECTION 5—WHEELCHAIR OPERATION
A Note About Drive Lock-Out
WARNING
NEVER operate the wheelchair or elevate/lower the seat while the back is in any
tilted/reclined/back angle position over 20° relative to the vertical position. If the
drive lock-out does not stop the wheelchair from operating or the seat from
elevating/lowering in a tilt/recline/back angle position over 20° relative to the
vertical position, DO NOT operate the wheelchair or elevate/lower the seat. DO
NOT attempt to adjust the drive lock-out. Have the wheelchair serviced by a
qualified technician.
The wheelchair user MUST have a clear line of sight to drive safely. On initial wheelchair delivery and after adjusting the back angle, drive lock-out switch, tilt system or
recline system, tilt and recline the seat back to the farthest driving position immediately before drive lock-out engages and ensure there is a clear line of sight present
in which to drive the wheelchair. If a clear line of sight is not present, have the back
angle repositioned or readjust the lockout angle such that safe driving with a clear
line of sight is achieved. Otherwise injury or damage may occur.
The LED on the single function toggle switch will light when the drive lock-out feature
has been activated. Drive lock-out is a feature designed to prevent the wheelchair from
being driven after the seating system has been tilted or reclined beyond 20°* relative to
the vertical position. The back can be positioned at a 10° relative offset to the seat base,
thereby resulting in a back angle potential of 30° before which the drive lock-out is
activated. This may affect the wheelchair user’s line of sight while driving. Make sure the
wheelchair user can see properly to ensure safe driving.
*NOTE: 20° back angle can be any combination of recline, tilt, back angle and/or surface angle.
NOTE: Refer to Typical Product Parameters for 2G Tarsys on page 23 or Elevating Seat/Power
Tilt Only on page 24 for tilt and/or recline angle ranges.

GENERAL WARNINGS
Refer to A Note About Drive Lock-Out on page 51 BEFORE performing this
procedure.
Pinch points may occur when returning the seat from any tilted position to the full
upright position or when lowering the elevating seat. Make sure the hands and body
of both the occupant and attendants/bystanders are clear of all pinch points before
returning the seat to the full upright position or lowering the elevating seat.
NEVER operate the wheelchair or elevate/lower the seat while the back is in any
tilted/reclined/back angle position over 20° relative to the vertical position. If the
drive lock-out does not stop the wheelchair from operating or the seat from
elevating/lowering in a tilt/recline/back angle position over 20° relative to the
vertical position, DO NOT operate the wheelchair or elevate/lower the seat. DO
NOT attempt to adjust the drive lock-out. Have the wheelchair serviced by a
qualified technician.

Part No 1134791
SECTION 5—WHEELCHAIR OPERATION
Vernier Shear Reduction (VSR) moves the back of the seating system along with the
recline function. VSR reduces shear between the user and the seating system as the
seating system reclines.
NOTE: VSR is electronically linked to the recline function of the seating system and operating the
recline function automatically activates VSR.
VSR function can also be used independently from the recline function to allow for a
change in seating position or access to additional seating system options. Refer to Using
Vernier Shear Reduction (VSR) Independently of Recline Function on page 57.
Using Vernier Shear Reduction (VSR) Independently of Recline Function
WARNING
The back of the seating system MUST be returned to original position before the
degree of recline is changed (increased or decreased). Otherwise, the relationship
between VSR and the recline function of the seating system will change, possibly
resulting in injury to the user.
1. Make sure the wheelchair is on a level surface.
2. Note the current position of the back.
3. Push four-way toggle switch toward the left of the wheelchair until the desired VSR is
achieved.
NOTE: Left and right are determined by standing behind the wheelchair.
NOTE: The four-way toggle switch will alternate functions (move VSR actuator up, move VSR
actuator down) after it has been released to the neutral position for a minimum of one second.
NOTE: If the wheelchair is equipped with switch options, scan to the correct ECU or Auxiliary
Mode and activate the control device in the corresponding "left" direction to operate the tilt

When to Charge Batteries
NOTE: For this procedure, refer to FIGURE 10.4.
MKIV-A and MKIV-RII Joysticks
The Battery Discharge Indicator (BDI) is a bar graph display located on the MKIV joystick.
It will keep you informed as to power availability. A visual warning is given before the
power becomes too low to operate the wheelchair. At full charge the two Left segments
and the farthest Right segment of the bar graph will be illuminated. As the battery
becomes discharged, the farthest Right segment will progressively move to the Left until
only the last two bars (Left) are illuminated. At this level the last two bars (Left) will start
to Flash On and Off to indicate that the end user should charge the batteries as soon as
possible.
MKIV-A+ Joysticks
The left half of the second line on the LCD is the Battery Discharge Indicator (BDI). It
provides information on the remaining charge in the batteries. At full charge solid blocks
fill in all ten segments between E (Empty) and F (Full). As the battery becomes
discharged, the farthest right segments will progressively disappear a half bar at a time
until no segments appear between E and F. At this level the word RECHARGE will appear
on the second line to indicate that the user should charge the batteries as soon as possible.

Charging Batteries
NOTE: For this procedure, refer to FIGURE 10.5.
NOTE: New batteries MUST be fully charged prior to initial use of the wheelchair.
WARNING
NEVER attempt to recharge the batteries by attaching cables directly to the
battery terminals or clamps. Always use the recharging plug located on the side of
the wheelchair frame.
DO NOT attempt to recharge the batteries and operate the power wheelchair at
the same time.
During use and charging, batteries may vent hydrogen gas, which is explosive in the
right concentration with air.
3G Storm Series® Wheelchairs
98
Part No 1134791
SECTION 10—BATTERIES
WARNING
DO NOT sit in wheelchair while charging batteries.
CAUTION
Always charge new batteries before initial use or battery life will be reduced.
NOTE: As a general rule, batteries should be recharged daily to assure the longest possible life and
minimize the required charging time. Plan to recharge the batteries when it is anticipated the
wheelchair will not be used for a long period of time.
The range per battery charge using recommended batteries should be approximately 5 to
9 hours of typical operation. Extensive use on inclines may substantially reduce per
charge mileage.
Description and Use of Battery Chargers
The charger automatically reduces the charge from an initially high rate to a zero reading
at a fully charged condition. If left unattended, the charger should automatically stop
charging when full charge is obtained.
There are some basic concepts which will help you understand this automatic process.
They are:
The amount of electrical current drawn within a given time to charge a battery is called
the “charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate
is high, as indicated by the green light on the charger. Initially, the green light will stay
illuminated for a short period of time followed by a longer period of off time. As a charge
builds up, the charge rate is reduced, and the green light will stay illuminated for a longer
period of time followed by a shorter off time.
WARNING
NEVER leave the charger unattended when the charger circuit breaker is tripping
on and off. A condition between the battery charger and batteries exists. Contact
an Invacare dealer.
NOTE: If performing the charging sections independently, read and carefully follow the individual
instructions for each charger (supplied or purchased).
NOTE: If charging instructions are not supplied, consult a qualified service technician for proper
instructions.
NOTE: Have the following tools available:
•
Battery Charger
•
Extension Cord*
*NOTE: 3-prong plug, 15 ampere current rating; industrial type.

1. Perform one of the following:
• Wheelchairs Equipped with MCC-MARK IV Joystick - Attach the battery charger
connector to the charger cable/battery harness.
NOTE: The battery charger connector is factory installed on the right side of the wheelchair. It
can be positioned on either side of the wheelchair for user convenience.
NOTE: For Recliners Only - If the wheelchair is a recliner, the battery charger connector as
well as the limit switch, are factory set on the right side of the wheelchair. However, they can
be positioned on either side for user convenience. The limit switch MUST be positioned on the
same side as the battery charger connector.
• Torque SP Equipped with MARK IV RII Joystick- Attach the battery charger
connector to the charger port on the Front of the joystick.
2. Plug the charger’s AC power cord, or extension, into the grounded 120 VAC wall
outlet.
3. Wait until charging is complete.
NOTE: It is advantageous to recharge frequently rather than only when necessary. In fact, a
battery’s life is extended if the charge level is maintained well above a low condition.
NOTE: If the batteries need to be charged more often or take longer to charge than normal, they
may need to be replaced. Contact an Invacare dealer for service.

The pelvic belt, provided by Invacare, has been designed to accommodate use on either
side of the vehicle. If necessary, follow the instructions below to reverse the orientation of
the pelvic belt to accommodate the vehicle-anchored upper-torso belt.
1. Install the pelvic belt pin (Detail "A" of FIGURE 17.2) into the large end of the slot in
the belt mounting bracket. Rotate downward and forward until it snaps into place into
the small end of the slot (Detail “B” or Detail “C”).
NOTE: Note the position of the male end of the belt when installing the pelvic belt onto the belt
mounting brackets. The male end of the pelvic belt (DETAIL "A" of FIGURE 17.2) has a pin which
is used to secure the vehicle-anchored upper-torso belt.
2. Repeat STEP 1 for the opposite belt mounting bracket.
3. Install the vehicle-anchored upper-torso belt onto the pin on the male end of the pelvic
belt.

Positioning Belts
WARNING
The angle of the pelvic belt should be
within the preferred zone of 45 to 75
degrees to the horizontal OR within the
optional zone of 30 to 45 degrees to the
horizontal.
Steeper side-view pelvic belt angles are
especially important if the pelvic belt is
intended to be used for postural support
in addition to occupant restraint in a
frontal crash. Steeper angles will reduce
the tendency for a vertical gap to
develop between the user and the belt
due to compliance of seat cushions and
belt movement, thereby reducing the
tendency for the user to slip under the
belt and for the belt to ride up on the
soft abdomen during normal use.
Side View
Preferred Zone
Optional Zone
45°
70°
30°
Steeper belt angles also reduce the tendency for upper-torso belts to pull the pelvic
belt onto the abdomen during frontal impact loading.
NOTE: For this procedure, refer to FIGURE 17.4.
1. The pelvic belt should be worn low across the front of the pelvis.
2. Position the upper-torso belt(s) over the shoulders.
3. The belt(s) should not be held away from the body by wheelchair components or
parts, including but not limited to wheelchair armrests or wheels. Refer to
FIGURE 17.4 for proper and improper positioning of the belts.
4. Ensure the belt(s) are not twisted.
5. Adjust belts as firmly as possible, being mindful of user comfort.
DO NOT POSITION BELT OUTSIDE OF
ARMRESTS, WHEELS, ETC.
DO POSITION BELT INSIDE OF
ARMRESTS, WHEELS, ETC.
