REPAIR OR SERVICE INFORMATION

If the wheelchair does NOT perform to specifications, turn the wheelchair OFF immediately and contact authorized dealer.

OPERATING INFORMATION

WARNING

To determine and establish your particular safety limits, practice bending, reaching and transferring activities in several combinations in the presence of a qualified health professional BEFORE attempting active use of the wheelchair.

DO NOT attempt to reach objects if you have to move forward in the seat. DO NOT attempt to reach objects if you have to pick them up from the floor by reaching down

between your knees. DO NOT lean over the top of the back upholstery to reach objects from behind as this may cause the

wheelchair to tip over. DO NOT shift your weight or sitting position toward the direction you are reaching as the wheelchair

may tip over. DO NOT tilt the wheelchair without assistance. DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur. Before attempting to transfer in or out of the wheelchair, every precaution should be taken to reduce

the gap distance. Turn both casters toward the object you are transferring onto. Also be certain the power is OFF and wheel locks are engaged to prevent the wheels from moving.

Wheel locks are an OPTION on this wheelchair, (you may order with or without wheel locks). Invacare strongly recommends ordering the wheel locks as an additional safeguard for the Action wheelchair user. Transfer to and from the wheelchair in the presence of a qualified healthcare professional to determine individual safety limits.

DO NOT engage or disengage the clutches until the power is in the OFF position. DO NOT operate on roads, streets or highways.

DO NOT climb, go up or down ramps or traverse slopes greater than 9 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 wheelchair. DO NOT use unauthorized parts, accessories, or adapters other than those authorized by Invacare. DO NOT leave the power ON when entering or exiting your wheelchair. 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 stand on the frame of the wheelchair. Anti-tippers MUST BE attached at all times. 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 wheelchair. ALW AYS wear your seat restraint.

SAFETY SUMMARY

SAFETY SUMMARY (CONTINUED)

TIRE PRESSURE DO NOT use your power 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.

ELECTRICAL Grounding Instructions:

DO NOT, under any circumstances, cut or remove the round gr ounding prong from any plug used with or for Invacare products. Some devices are equipped with three-pr ong (gr ounding) 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 W ARNING TAGS on some equipment. DO NOT remove these tags. Carefully read battery/battery charger information prior to installing, servicing or operating your wheelchair.

RAIN TEST INVACARE has tested it’s Action power wheelchairs in accordance with ISO 7176 Part 9 “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 your power wheelchair in a rain storm of any kind. DO NOT use your power wheelchair in a shower or leave it in a damp bathroom while taking a shower. DO NOT leave your power wheelchair in a damp area for any length of time. Direct exposure to rain or dampness will cause the wheelchair to malfunction electrically and me-

chanically; may cause the wheelchair 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 IMMEDIA TELY.

SAFETY SUMMARY

SAFETY SUMMARY (CONTINUED)

U M M

CAUTION:

T IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EFFECTS OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR.

WARNING

Electromagnetic Interference (EMI) From Radio Wave sources Powered wheelchairs and motorized scooters (in this text, both will be referred to as powered wheel-

chairs) may be susceptible to electromagnetic interference (EMI), which is interfering electromagnetic energy (EM) emitted from sour ces 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 fr om the more common sources of radiated EMI. This powered wheelchair model as shipped, with the MKIV-RII-LP controller has an unknown immunity level.

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 exposur e is unavoidable. However, we believe that by following the warnings listed, your risk to EMI will be minimized.

The sources of radiated EMI can be broadly classified into thr ee 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.

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 are recommended to prevent possible interference with the control system of the powered wheelchair.

SAFETY SUMMARY

SAFETY SUMMARY (CONTINUED)

WARNINGS

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 MKIV-RII-LP controller has an unknown immunity level. P7E Frame with MKIV-RII Joystick.

Modification of any kind to the electronics of this wheelchair as manufactured by Invacare may adversely affect the RFI immunity levels.

“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 tech-

niques 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 encoun-

ter. Techniques in this manual are a starting point for new wheelchair users and assistants with “safety” as the most important consideration for all.

STABILITY AND BALANCE

WARNING

AL WAYS WEAR YOUR SEAT RESTRAINT. To assure stability and proper operation of your

wheelchair, you must at all times maintain proper balance. Y our 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 alleviated somewhat 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 the wheelchair or traversing curbs, or other impediments.

Also, be aware of detachable parts such as arms or legrests. These must NEVER be used for hand-hold or 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.

TILTING

WARNING

DO NOT tilt the wheelchair without assistance.

When tilting the wheelchair, an assistant should grasp the back of the wheelchair on a non-removable (nondetachable) part. Inform the wheelchair occupant before tilting the wheelchair and remind him/her to lean back. Be sure the occupant’s feet and hands are clear of all wheels.

TILTING - CURBS:

After mastering the techniques of tilting the wheelchair, use this procedure to tackle curbs, short stairs, etc.

Unless the first assistant has exceptional upper body strength, it is recommended that this procedure be performed with two (2) assistants. The second assistant should be positioned at the front of the wheelchair lifting upward on a non-removable (non-detachable) part of the wheelchair frame when lifting the wheelchair and stabilizing the wheelchair when the wheelchair is being lowered to the ground.

The first assistant should turn the anti-tippers so the wheels are pointing up, apply a continuous downward motion until the balance point is achieved and the front casters clear the curb. At this point, the assistants will feel a difference in the weight distribution.

Roll the wheelchair forward and Slowly lower the wheelchair in one continuous movement. Do not let the wheelchair drop the last few inches to the ground. This could result in injury to the occupant. Push the wheelchair forward until the rear wheels roll up and over the curb.

WARNING

Make sure anti-tipper wheels are pointing down towards the ground/floor BEFORE using the wheelchair.

Turn the anti-tipper wheels down towards the

ground/floor.

TILTING: CURBS

SAFETY/HANDLING

STAIRWAY

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 (2) assistants and making thorough preparations. Make sure to use ONLY secure, non-detachable parts for hand-hold supports.

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.

Follow this procedure for moving wheelchair between floors when an elevator is NOT available:

CAUTION

The weight of the wheelchair without the user and batteries is still over 78 lbs. Use proper lifting techniques (lift with legs) to avoid injury.

1. Remove the occupant from the wheelchair.

2. Remove the battery box(es) from the rear of the wheelchair. Refer to INSTALLING/REMOVING BATTERY BOX(ES) in PROCEDURE 6 of this manual.

3. Remove the anti-tippers from the wheelchair. Refer to INSTALLING/REMOVING THE ANTI-TIPPERS in PROCEDURE 10 of this manual.

4. Disengage the clutches. Refer to ENGAGING/DISENGAGING CLUTCHES in PROCEDURE 10 of this manual.

5. After the wheelchair has been tilted back to the balance point, one assistant (in the rear) backs the wheelchair up against the first step, while securely grasping a non-removable (non-detachable) part of the wheelchair for leverage.

6. The second assistant, with a firm hold on a non-detachable part of the framework, lifts the wheelchair up and over the stair and steadies the wheelchair as the first assistant places one (1) foot on the next stair and repeats STEP 1.

7. The wheelchair should not be lowered until the last stair has been negotiated and the wheelchair has been rolled away from the stairway.

WARNING

Make sure anti-tipper wheels are pointing down towards the ground/floor BEFORE using wheelchair.

3. Reinstall the anti-tippers to the wheelchair. Refer to INSTALLING/REMOVING THE ANTI-TIPPERS in PROCEDURE 10 of this manual.

9. Engage the clutches. Refer to ENGAGING/DISENGAGING CLUTCHES in PROCEDURE 10 of this manual.

ESCALATORS? SORRY!

DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur.

TRANSFERRING TO/FROM OTHER SEATS

WARNING

BEFORE attempting to transfer in or out of the wheelchair, every precaution should be taken to reduce the gap distance. Turn both casters toward the object you are transferring onto. Also be certain the wheel locks* are engaged to help prevent the wheels from moving.

*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 Action wheelchair user.

CAUTION

When transferring, position yourself as far back as possible in the seat. This will prevent broken screws, damaged upholstery and the possibility of the wheelchair tipping forward.

T Y

H A N D

N G

Position the wheelchair as close as possible along side the seat to which you are transferring, with the front casters pointing toward it. Engage wheel locks*. Shift body weight into seat with transfer.

During independent transfer, little or no seat platform will be beneath you. Use a transfer board if at all possible.

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 owner to reach, bend and transfer in and out of the wheelchair. These movements will cause a change to 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 health 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 front casters as a tool to maintain stability and balance.

REACHING, LEANING, BENDING AND BENDING - FORWARD

Position the front casters so that they are extended as far forward as possible and engage wheel locks*. DO NOT LEAN FORWARD OF THE ARMRESTS.

WARNING

FUNCTIONAL REACH FROM A WHEELCHAIR

The approximate reach-limit values shown in the accompanying graphs were derived on the basis of a sample of 91 male and 36 female subject wheelchair users. Note the difference between the maximum and the comfortable reach limits, a subjective but important consideration in design.

REACHING, BENDING - BACKWARDS

WARNING

DO NOT lean over the top of the back upholstery. This will change your center of gravity and may cause you to tip over.

Position wheelchair as close as possible to the desired object. Point front casters forward to create the longest possible wheelbase. Reach back only as far as your arm will extend without changing your sitting position.

Don’t tip or tilt batteries. Don’t use ordinary tap water. Don’t overfill cells. Don’t use uneven levels of distilled

water in the cells. Don’t tap on the clamps and ter-

minals with tools. Don’t mismatch your battery

and chargers.

WARNING

Read and understand this manual and any service information that accompanies a battery and charger before operating the wheelchair.

Move the wheelchair to a work area before checking the fluid level, adding distilled water, cleaning terminals, or opening battery box(es).

Recharge as frequently as possible to maintain a high charge level and extend battery life.

Follow recommendations in this manual when selecting a battery or charger.

Fully charge a new battery before using. Use a carrying strap to remove, move or install a battery. ONL Y use distilled water to refill. Keep the liquid level in the cells at the “split ring” level. Maintain the liquid in all cells at the “split ring” level. Push the battery clamps on the terminals. Spread clamps

wider if necessary. Use ONLY a GEL charger or GEL setting for a GEL or sealed

battery and a regular charger or regular setting (wet) for regular batteries.

FIELD LOAD TEST

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.

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 side of the wheelchair frame.

NOTE: READ the instructions CAREFULLY before using the digital voltmeter.

TROUBLESHOOTING

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 front of the wheelchair against a wall, workbench or other stationary object.

VOLTMETER TO THE WHEELCHAIR

4. Place the voltmeter leads into the charger plug on the wheelchair. Most digital voltmeters are not affected 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 power 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.

USING HYDROMETER TO CHECK BATTERY CELLS (DIGITAL VOLTMETER NOT AVAILABLE) (LEAD ACID) (FIGURE 2)

WARNING

Invacare recommends that the following procedure be performed by an Authorized Dealer or Qualified Service Technician.

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 safety glasses is recommended when testing the battery cells.

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 IMMEDIA TEL Y .

The battery acid can damage your wheelchair, clothing, and household items. Therefore, take readings cautiously and only in designated areas.

Most batteries are not sold with instructions. However, warnings are frequently noted on the cell caps. Read them carefully.

CAUTION

ONLY use distilled water when topping off the battery cells. Ordinary tap water will shorten the life of the battery.

1. Remove the battery box(es) from the wheelchair. Refer to INSTALLING/REMOVING BATTERY BOX(ES) in PROCEDURE 6 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.

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.

5. Draw up sufficient acid to cover float balls.

6. Tap lightly to remove air bubbles.
