WHEELCHAIR USER
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of
Action 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 appropri-
ate 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 wheel-
chair 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 SEAT-
ING POSITIONING STRAP IS REQUIRED TO ENSURE THE SAFE OPERATION OF THIS EQUIP-
MENT BY THE USER. SERIOUS INJURY CAN OCCUR IN THE EVENT OF A FALL FROM A WHEEL-

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 GENERAL WARNINGS
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 set-
tings 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 speci-
fications. Repeat this procedure until the wheelchair performs to specifications.
DO NOT use parts, accessories, or adapters other than those authorized by Invacare.
TIRE PRESSURE
DO NOT use your wheelchair unless it has the proper tire pressure (P.S.I.). DO NOT overin-
flate 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.
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 Elec-
trical 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 re-
move these tags. Carefully read battery/battery charger information prior to installing,
servicing or operating your wheelchair.
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.
Battery connecting cables are NOT interchangeable. Battery connecting cables with
single fuse setup MUST only be used on wheelchairs with conventional motor/gearbox
assembly. Otherwise, damage may result. Refer to INSTALLING/REMOVING BATTERIES
INTO/FROM BATTERY BOX(ES) in PROCEDURE 9 of this manual.

FIELD LOAD TEST (FIGURE 1)
NOTE: The following test can also be performed through
the controller of the wheelchair along with a remote pro-
grammer. Refer to the individual CO TROLLER
MA UAL 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 rom the battery, some o that power is used up
in the process o 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 or a pair), replace the batteries.
Testing under load is the only way to spot this problem.
While special battery load testing equipment is available,
it is costly and di icult to transport.
Use a digital voltmeter to check battery charge level at the charger
connector. It is located on the base o the wheelchair rame.
NOTE: READ the instructions CAREFULLY before us-
ing the digital voltmeter.
NOTE: Invacare recommends that O LY qualified ser-
vice personnel perform this test.
1. Ensure that power is OFF.
2. Make sure battery is ully charged. An extremely dis-
charged battery will exhibit the same symptoms as a
bad one.
3. Remove the ootrests rom the wheelchair and per-
orm one (1) o the ollowing:
A. RWD MODELS - place the CASTERS o the
wheelchair against a wall, workbench or other
stationary object.
B. MWD MODELS - place the STABILIZER
wheels o the wheelchair against a wall, work-
bench or other stationary object.
C. WD MODELS -place the DRIVE wheels o
the wheelchair against a wall, workbench or
other stationary object.
USING HYDROMETER TO CHECK
BATTERY CELLS (LEAD ACID)
(FIGURE 2)
NOTE: erform 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.

This Procedure Includes the Following:

Using Hydrometer To Check Battery Cells (Lead
Acid)
Motor Testing
Motor Brush Inspection
Electro-Mechanical Parking Brake Testing
4. Place the voltmeter leads into the charger plug on the
wheelchair. Most digital voltmeters are not a ected by
polarity, however, analog meters (meters with swing-
ing needles) can be and should be used care ully. 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
o the wheelchair.
6. Turn the wheelchair ON and push the joystick or-
ward, trying to drive the wheelchair through the sta-
tionary 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.

WARNING
When reading a hydrometer, DO NOT al-
low 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 wheel-
chair, 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 INSTALLING/
REMOVING ATTERY OXES - GROUP 24 AT-
TERY ASE FRAMES or INSTALLING/REMOVING
ATTERY OX - GROUP 22 ATTERY ASE
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.
NOTE: DO NOT fill hydrometer more than 3/4 full.
5. Draw up sufficient acid to cover float balls.
6. Tap lightly to remove air bubbles.
7. Number of floating balls indicates charge.
Number of Floating Balls
0 Discharged
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 prop-
erly read. A shorted or dead cell can be detected when
it is the only cell that does not charge.
FIGURE 2 - USING HYDROMETER TO CHECK
BATTERY CELLS (LEAD ACID)
Number of Floating
Balls Will Vary
ccording to Charge
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/RE-
MOVING ATTERY OXES - GROUP 24 ATTERY
ASE FRAMES or INSTALLING/REMOVING AT-
TERY OX - GROUP 22 ATTERY ASE FRAMES
in PROCEDURE 9 of this manual.
MOTOR TESTING (FIGURE 3)
NOTE: This procedure should only be performed on
wheelchairs with the conventional motor/gearbox assem-
bly. For gearless/brushless motors, there are no service-
able parts. Return motor to manufacturer for testing.
1. On the 4-pin motor connector, locate the two (2) con-
tacts 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: normal reading is between 1 and 5 ohms
(Ω). 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.

ELECTRO-MECHANICAL PARKING
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 con-
tacts. 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 connec-
tion respectively. If either condition exists, send the motor
to Invacare Technical Service for inspection/repair.
CAUTION
A shorted electro-mechanical brake will
damage the brake output section in the con-
troller. DO NOT connect a shorted electro-
mechanical brake to a good controller mod-
ule. A shorted brake MUST be replaced.
NOTE: bad motor can damage the controller module
but a bad controller will NOT damage a motor.

MOTOR BRUSH INSPECTION
(FIGURE 4)
NOTE: This procedure should only be performed on wheel-
chairs with conventional motor/gearbox assembly.
There are two (2) contact brushes on ACTION STORM mo-
tors 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-be-
tween. 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.
