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 POSITIONING STRAPS
Invacare recommends that wheelchair users 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.
AS REGARDS RESTRAINTS - SEAT POSITIONING STRAPS - IT IS THE OBLIGATION OF THE DME
DEALER, THERAPISTS AND OTHER HEALTHCARE PROFESSIONALS TO DETERMINE IF A SEATING
POSITIONING STRAP IS REQUIRED TO ENSURE THE SAFE OPERATION OF THIS EQUIPMENT BY
THE USER. SERIOUS INJURY CAN OCCUR IN THE EVENT OF A FALL FROM A WHEELCHAIR.

REPAIR OR SERVICE INFORMATION
Set-up of the Electronic Control Unit is to be performed ONLY by individuals certified by
Invacare. The final tuning adjustments of the controller may affect other activities of
the wheelchair. Damage to the equipment could occur under these circumstances. If
non-certified individuals perform any work on these units, the warranty is void.
OPERATING INFORMATION
Performance adjustments should only be made by professionals of the healthcare field
or persons fully conversant with this process and the driver's capabilities. Incorrect
settings could cause injury to the driver, bystanders, damage to the chair and to surrounding property.
After the wheelchair has been set-up, check to make sure that the wheelchair performs to the specifications entered during the set-up procedure. If the wheelchair
does NOT perform to specifications, turn the wheelchair OFF immediately and reenter
set-up specifications. Repeat this procedure until the wheelchair performs to specifications.
GENERAL GUIDELINESPROCEDURE 1
GENERAL WARNINGS
DO NOT operate on roads, streets or highways.
DO NOT climb, go up or down ramps or traverse slopes greater than 9
o
.
DO NOT attempt to move up or down an incline with a water, ice or oil film.
DO NOT attempt to drive over curbs or obstacles. Doing so may cause your wheelchair
to turn over and cause bodily harm or damage to the chair.
DO NOT use parts, accessories, or adapters other than those authorized by Invacare.
DO NOT leave the power button ON when entering or exiting your wheelchair.
DO NOT stand on the frame of the wheelchair.
DO NOT use the footplates as a platform. When getting in or out of the wheelchair,
make sure that the footplates are in the upward position or swing footrests towards the
outside of the chair.
ALWAYS wear your seat positioning strap.
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 suggestions may cause the tire to explode
and cause bodily harm. The recommended tire pressure is listed on the side wall of the
tire.

GENERAL WARNINGS (CONTINUED)
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 or sealed lead acid batteries. Invacare strongly
recommends their use as the power source for this unit.

RAIN TEST
INVACARE has tested it’s power wheelchairs in accordance with ISO 7176 Part 9
“Rain Test”. This provides the end user or his/her attendant 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.
DO NOT use power wheelchair in a shower or leave it in a damp bathroom while
taking a shower.
DO NOT leave power wheelchair in a damp area for any length of time.
Direct exposure to rain or dampness will cause the chair to malfunction electrically
and mechanically; may cause the chair to prematurely rust.
Check to ensure that the battery covers are secured in place, 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.
WEIGHT TRAINING
Invacare DOES NOT recommend the use of its wheelchairs as a weight training
apparatus. Invacare wheelchairs have NOT been designed or tested as a seat
for any kind of weight training. If occupant uses said wheelchair as a weight
training apparatus, INVACARE SHALL NOT BE LIABLE FOR BODILY INJURY AND THE
WARRANTY IS VOID.

FIELD LOAD TEST (FIGURE 1)
NOTE: The following test can also be performed through
T
the controller of the wheelchair along with a remote pro-
I
grammer. Refer to the individual CONTROLLER
N
MANUAL supplied with each wheelchair.
Old batteries lose their ability to store and release power, due
to increased internal resistance. This means that as you try
to take power from the battery , some of that power is used up
in the process of passing through the battery , resulting in less
voltage at the posts. The more power drawn, the lower the
voltage available. When this lost voltage drops the output 1.0
volts under load (2.0 for a pair), replace the batteries.
4. Place the voltmeter leads into the charger plug on the
wheelchair. Most digital voltmeters are not af fected by
polarity , however, analog meters (meters with swinging needles) can be and should be used carefully . A
good meter reading should be 25.5 to 26 VDC.
5. Have two (2) individuals (one [1] on each arm) apply
as much downward pressure as possible on the arms
of the wheelchair.
6. Turn the wheelchair ON and push the joystick forward, trying to drive the wheelchair through the stationary object. This puts a heavy load on the batteries
as they try to push through the stationary object. Read
the meter while the motors are straining to determine
the voltage under load.
NOTE: If the voltage drops to less than 23.5 volts from a
pair of fully charged batteries while under load, they should
be replaced regardless of the unloaded voltages.
Battery Charger
(-)
Connector
(+)
Testing under load is the only way to spot this problem.
While special battery load testing equipment is available,
it is costly and difficult to transport.
Use a digital voltmeter to check battery charge level at the charger
connector. It is located on the base of the wheelchair frame.
NOTE: READ the instructions CAREFULLY before using the digital voltmeter.
NOTE: Invacare recommends that ONLY qualified ser-
vice personnel perform this test.
1. Ensure that power is OFF.
2. Make sure battery is fully charged. An extremely discharged battery will exhibit the same symptoms as a
bad one.
3. Remove the footrests from the wheelchair and place
the CASTERS of the wheelchair against a wall,
workbench or other stationary object.

NOTE: Perform this procedure when a digital voltmeter is
not available.
WARNING
NEVER smoke or strike a match near the
batteries. If the caps of the battery cells
are removed, NEVER look directly into
them when charging the battery.
The use of rubber gloves and chemical
goggles or face shields is recommended
when working with batteries.

TROUBLESHOOTING
WARNING
PROCEDURE 2
When reading a hydrometer, DO NOT allow any liquid to come in contact with
your eyes or skin. It is a form of acid and
can cause serious burns, and in some
cases, blindness. If you do get battery acid
on you, flush the exposed areas with cool
water IMMEDIATELY. If the acid comes into
contact with eyes or causes serious burns,
get medical help IMMEDIATELY.
The battery acid can damage your wheelchair, clothing, and household items.
Therefore, take readings cautiously and
only in designated areas.
ONLY use distilled water when topping off
the battery cells.
Most batteries are not sold with instructions.
However, warnings are frequently noted
on the cell caps. Read them carefully.
1. Remove the battery box(es). Refer to
INST ALLING/
REMOVING BA TTERY BOXES - GROUP 24 BA TTERY BASE FRAMES or INST ALLING/REMOVING
BA TTERY BOX - 22NF BATTER Y BASE FRAMES
in PROCEDURE 9 of this manual.
2. Remove the battery caps from the battery .
3. Squeeze the air from the hydrometer.
4. Place the hydrometer into a battery cell.

According to Charge
FIGURE 2 - USING HYDROMETER TO CHECK
BATTERY CELLS (LEAD ACID)
9. Flush hydrometer in cold running water by allowing
the water to rise into hydrometer as far as possible.
Do this several times to guard against burn damage.
10. Replace the battery caps.
11. Reinstall battery boxes. Refer to
INSTALLING/REMOVING BA TTERY BOXES - GROUP 24 BATTERY
BASE FRAMES or INST ALLING/REMOVING BA TTERY BOX - 22NF BATTERY BASE FRAMES in
PROCEDURE 9 of this manual.

1 25% Charged
2 50% Charged
3 75% Charged
4 100% Charged
* 5 Overcharged
* Check charging system.
8. Flush the liquid back into the same cell after reading
the float. Repeat this step until all cells have been properly read. A shorted or dead cell can be detected when
it is the only cell that does not charge.
1. On the 4-pin motor connector, locate the two (2) contacts in the red and black housings.
2. Set the digital multimeter to measure ohms (Ω).
3. Measure the resistance between the two (2) motor
contacts.
NOTE: A normal reading is between 1 and 5 ohms
(Ω). A reading of 0 ohms (Ω) or in excess of 15 ohms
(Ω) indicates a problem. High readings are generally
caused by bad connections and/or damaged brushes.
Contact authorized dealer or Invacare.

MOTOR BRUSH INSPECTION
(FIGURE 4)
NOTE: This procedure should only be performed on wheelchairs with conventional motor/gearbox assembly .
There are two (2) contact brushes on STORM motors
located under the brush caps on the motor housing. If
these caps are hard to remove they are either overtightened or the motor has become very hot. Let motors cool. If caps still cannot be removed, it is recommended that the motor be sent to Invacare Technical
Services for inspection/repair.
NOTE: It is very important to note which way the brush
comes out of the motor. The brush MUST be placed into
the motor exactly the same way to ensure good contact
with the commutator.
1. Once the motor brush caps have been removed, pull
the brushes out of the motor. The end of the brushes
should be smooth and shiny and the spring should
not be damaged or discolored. If one or both of the
brushes are damaged, only the damaged or worn
brushes need be replaced. It is very important that
any time a brush is replaced, it must be “burned in”.
This is accomplished by running the motor for one
hour in each direction with a half hour break in-between. This should also be done with little or no load
on the motor, i.e., put the wheelchair up on blocks so
the drive (large) wheels do not contact the ground
and run the wheelchair. A motor with only one brush
replaced will only carry a small percentage of its rated
load capacity until the NEW brush is burned in.

BRAKE TESTING (FIGURE 5)
NOTE: This procedure should only be performed on
wheelchairs with conventional motor/gearbox assembly .
1. On the four-pin motor connector, locate the side by
side connectors in the black housings.
2. Set the digital multimeter to read ohms (Ω).
3. Measure the resistance between the two (2) brake contacts. A normal reading is 100 ohms (Ω). A reading of 0
ohms (Ω) or a very high reading; i.e., MEG ohms or O.L.
(out of limit) indicates a shorted brake or an open connection respectively . If either condition exists, send the motor
to Invacare T echnical Service for inspection/repair.
CAUTION
A shorted electro-mechanical brake will
damage the brake output section in the controller. DO NOT connect a shorted electromechanical brake to a good controller module. A shorted brake MUST be replaced.
NOTE: A bad motor can damage the controller module
but a bad controller will NOT damage a motor.
