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 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 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.

GENERAL GUIDELINESPROCEDURE 1
This Procedure Includes the Following:
Repair or Service Information
Operating Information
Safety/Handling of Wheelchairs
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
settings could cause injury to the driver, bystanders, damage to the chair and to sur-
rounding property.
After the wheelchair has been set-up, check to make sure that the wheelchair per-
forms 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 specifi-
cations.
DO NOT operate on roads, streets or highways.
DO NOT climb, go up or down ramps or traverse slopes greater than 9o.
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 re-
placed 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 con-
nected. 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.
Carefully read battery/battery charger information prior to installing, servicing or
operating your wheelchair.
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.

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 BATTERY BOXES - GROUP 24 BAT-
TERYBASEFRAMESorINSTALLING/REMOVING
BATTERY BOX - 22NF BATTERY BASE FRAMES
in PROCEDURE 9 of this manual.
2. Remove the battery caps from the battery.
3. Squeeze the air from the hydrometer.
4. Placethehydrometer intoa batterycell.
NOTE: DO NOT fill hydrometer more than 3/4 full.
5. Draw up sufficient acid to cover float balls.
6. Taplightlytoremoveairbubbles.
7. Numberof 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
thefloat.Repeatthisstepuntilallcellshavebeenprop-
erlyread.Ashortedordeadcellcanbedetectedwhen
itis the only cell that doesnot charge.

9. Flush hydrometer in cold running water by allowing
the water to rise into hydrometer as far as possible.
Dothis severaltimes to guardagainst burndamage.
10. Replace the battery caps.
11. Reinstall battery boxes. Refer to INSTALLING/RE-

MOTOR TESTING (FIGURE 3)
NOTE: This procedure should only be performed on
wheelchairswiththeconventionalmotor/gearboxassem-
bly. For gearless/brushless motors, there are no service-
able parts. Return motor to manufacturer for testing.
1. Onthe4-pinmotorconnector,locatethetwo(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: 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
causedbybadconnectionsand/ordamagedbrushes.
Contact authorized dealer or Invacare.

BRAKE TESTING (FIGURE 5)
NOTE: This procedure should only be performed on
wheelchairswith conventionalmotor/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

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.

MOTOR BRUSH INSPECTION
(FIGURE 4)
NOTE:Thisprocedureshouldonlybeperformedonwheel-
chairs 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 over-
tightened or the motor has become very hot. Let mo-
tors cool. If caps still cannot be removed, it is recom-
mended 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 brushMUST be placed into
the motor exactly the same way to ensure good contact
withthecommutator.
1. Oncethemotorbrushcapshavebeenremoved,pull
thebrushes outof the motor.Theendof thebrushes
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
onthe motor, i.e., putthe wheelchair up on blocksso
the drive (large) wheels do not contact the ground
and run the wheelchair. A motor with only one brush
replacedwillonlycarryasmallpercentageofitsrated
load capacity until the NEW brush is burned in.
