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.
0
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,

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-
I
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.

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.

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.
I
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
*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.
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.

Invacare recommends that the following procedures be performed by an Authorized Dealer or Quali­fied Service Technician.
The following “Do’s” and “Don’ts” are provided for your convenience and safety.
DON’T DO
Don’t perform any installation or maintenance without first reading this manual.
Don’t perform installation or main­tenance of batteries in an area that could be damaged by battery spills.
Don’t make it a habit to discharge batteries to the lowest level.
Don’t use randomly chosen batter­ies or chargers.
Don’t put new batteries into service before charging.
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.
16
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.

FIGURE 1 - CONNECTING THE DIGITAL
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.

MOTOR BRUSH INSPECTION (FIGURE 4)
WARNING
Invacare recommends that the following proce­dures be performed by an Authorized Dealer or Qualified Service Technician.
Long End Cap Motors (Internally Concealed Brushes)
NOTE: There are two (2) contact brushes on P7E motors.
Motor brushes are located under the motor end cap. Re­move the end cap, by removing the two (2) phillip screws.
NOTE: It is very important to note which way the brush comes out of the motor. It MUST be placed into the motor exactly the same way to ensure good contact with the commutator.
18
TROUBLESHOOTING
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 rear of the wheelchair up on blocks 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.

ELECTROMECHANICAL PARKING BRAKE TESTING (FIGURE 5)
WARNING
Invacare recommends that the following proce­dures be perfor med by an Invacare Dealer or Qualified Service Technician.
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.
3. Measure the resistance between the two (2) brake contacts. A normal reading is 100 ohms (W). A read­ing of 0 ohms (W) 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, it is recommended that the motor be sent to Invacare Technical Service for inspection/repair.
CAUTION
A short circuited brake will damage the brake output section in the controller. DO NOT connect a bad electromechanical brake to a good con­troller module. A shorted electromechanical brake MUST be replaced.

BATTERIES
WHEN TO CHARGE BATTERIES (FIGURE 5)
It is advantageous to recharge frequently rather than only when necessary. In fact, a batterys life is extended if the charge level is maintained well above a low condition.
MKIV-RII Joystick
BATTERY GAUGE DISPLAY (BGD) - Located at the front of the joystick housing provides information on the remaining charge in the batteries. At full charge the BGD will be Green. As the battery becomes discharged, the BGD will become Yellow (Amber), then Red and finally the BGD will flash ON and OFF Red. At this level, the user should charge the batteries as soon as possible.

FIGURE 5 - WHEN TO CHARGE BATTERIES
CHARGING THE BATTERIES (FIGURE 6)
NOTE: New batteries MUST be fully charged prior to ini­tial use of the wheelchair.
WARNING
Always charge new batteries before initial use or battery life will be reduced.
As a general rule, you should recharge your bat­teries as frequently as possible to assure the long­est possible life and to minimize the required charging time. Plan to recharge them when you do not anticipate using the wheelchair for a long period of time.
Never attempt to recharge the batteries by at­taching cables directly to the battery terminals or clamps. Use the recharging plug located on either the side of the wheelchair frame or on the front of the joystick.
DO NOT attempt to recharge the batteries and operate the power wheelchair at the same time.
42
PROCEDURE 6BATTERIES
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 Charger ­Standard 4 AMP Battery Charger
The charger automatically reduces the charge from an ini­tially high rate to a zero reading at a fully charged condition.
NOTE: The Charger output and green light will stay ON until the power switch on the battery charger is moved to the OFF position.
There are some basic concepts which will help you understand this automatic process:
The amount of electrical current drawn within a given time to charge a battery is called charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate is high. As a charge builds up, the charge rate is reduced and the battery charger rate decreases to a "trickle charge".
NOTE: If performing the charging procedures indepen­dently, READ and CAREFULLY follow the individual in­structions for each charger (supplied or purchased).
NOTE: The Charger output and green light will stay ON until the power switch on the battery charger is moved to the OFF position.
Wheelchairs Equipped With Mark IV RII Joystick (Detail "B" of FIGURE 6)
1. Attach the battery charger connector to the charger port on the FRONT of the joystick.
2. Plug the chargers AC power cord, or extension, into the grounded 120 VAC wall outlet.
3. Wait until charging is complete.
NOTE: Allow eight (8) hours for normal charging. Larger batteries (greater than 55 ampere-hours) or severely dis­charged batteries may require up to sixteen (16) hours to be properly charged and equalized. If the charger oper­ates for sixteen (16) hours and is unable to fully charge the batteries, an internal timer turns the charger off and begins to fast blink the green light.
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.
