EXTREME care should be exercised when using oxygen in close proximity to electric circuits. Contact your oxygen supplier for instruction in the use of oxygen.

BA TTERIES 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.

The use of rubber glovesand safety glasses is recommended when working with batteries. Carefully read battery/battery charger information prior to installing, servicing or operating your wheelchair .

GROUNDING INSTRUCTIONS: DO NOT , under any circumstances, cut or remove the round grounding pr ong from any plug used with

or for Invacare products. Some devices are equipped with thr ee-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 ONL Y 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 T AGS on some equipment. DO NOT remove these tags.

RAIN TEST INVACARE has tested it’s power wheelchairs in accordance with ISO 7176 Part 9 “Rain T est”. 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.

GENERAL GUIDELINES PROCEDURE 1

SAFETY/HANDLING OF WHEELCHAIRS

“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 techniques 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 encounter, however , ALL W ARNINGS and CAUTIONS given in this manual MUST be followed. T echniques in this manual are a starting point for the new wheelchair user and assistant with “safety” as the most important consideration for all.

Stability and Balance

WARNING

ALW AYS wear your seat positioning strap.

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.

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 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.

Stairways

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 ONL Y 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 the wheelchair between floors when an elevator is NOT available:

WARNING

The weight of the wheelchair without the user and batteries is still between 83 and 142 lbs. Use proper lifting techniques (lift with your legs) to avoid injury.

1. Remove the occupant from the wheelchair.

2. Remove the battery boxes from the wheelchair . Refer to one (1) of the following:

FWD WHEELCHAIRS -

INSTALLING/REMOVING

BATTERY BOXES in PROCEDURE 1 1 of this manual. MWD WHEELCHAIRS -

INSTALLING/REMOVING

BATTERY BOXES in PROCEDURE 12 of this manual.

3. Bend your knees and keep your back straight.

4. Using non-removable (non-detachable) parts of the wheelchair, lift the wheelchair off of the ground and transfer the wheelchair up or down the stairs.

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

ESCALA TORS? SORRY !

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

GENERAL GUIDELINESPROCEDURE 1

Transferring to and From Other Seats

E R A

L G

ALW AYS turn the wheelchair power OFF and engage the motor locks/clutches to prevent the wheels from moving BEFORE attempting to transfer in or out of the wheelchair. Also, make sure every precaution is taken to reduce the gap distance aligning both rear casters parallel with the object you are transferring onto.

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.

NOTE: This activity may be performed independently provided you have adequate mobility and upper body strength.

WARNING

CAUTION

1. Position the wheelchair as close as possible along side the seat to which you are transferring, with the rear casters pointing away from it.

2. Engage motor locks/clutches. Refer to one (1) of the following.

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 user 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 . T o determine and establish your particular safety limits, practice bending, reaching and transferring activities in several combinations in the presence of a qualified healthcare 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 rear casters as a tool to maintain stability and balance.

RII MWD WHEELCHAIRS ONLY.

WARNING

NEVER reposition the motors. Repositioning the motors rearward WILL reduce the stability of the wheelchair. This procedure MUST be performed by an Invacare Dealer.

be beneath you. Use a transfer board if at all possible.

RII FWD MODEL WHEELCHAIRS ONLY (FIGURE 1).

WARNING

The overall perfor mance of the wheelchair WILL be affected by the front wheel mounting position. The following charts show the mounting position of the motors for each seat width and depth depending on the factory setting or user's weight.

If the mounting position that corresponds to the user's weight is different than the factory setting, the mo-

MINIMIZE GAP

DISTANCE

tors MUST BE repositioned to maintain proper stability and controllability BEFORE using the wheelchair. Otherwise injury or damage can occur .

Periodically review the following charts to make sure the motor mounting position still corresponds to the user's weight to maintain the proper stability and controllability.

Repositioning the motors MUST be perfo rmed by an Invacare Dealer .

RANGER IIJR ON LY - NEVER reposition the motors. Repositioning the motors forward WILL reduce the controllability of the wheelchair. This procedure MUST be performed by an Invacare Dealer .

NOTE: If motors are repositioned, the front riggings may need to be repositioned. Refer to

WARNING

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

GENERAL GUIDELINES

WARNING

CAUTION: IT IS VERY IMPORT ANT THAT YOU READ THIS INFORMA TION REGARDING THE POSSIBLE EFFECTS OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR.

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 interf erence (EMI), which is interfering electr omagnetic energy (EM) emitted from sources 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 from the more common sources of radiated EMI. This powered wheelchair model as shipped 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 below, your risk to EMI will be minimized.

The sources of radiated EMI can be broadly classified into three 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.

GENERAL GUIDELINES PROCEDURE 1

WARNING

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

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 i s 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 MCC MKIV controller for this application has an unknown immunity level.

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