NOTICE

THE INFORMATION CONTAINED IN THIS DOCUMENT IS SUBJECT TO

CHANGE WITHOUT NOTICE.

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 RESTRAINTS (TRRO AND

TRBKTS)

TRRO includes four factory-installed transport brackets and a wheelchair anchored

pelvic belt. TRRO has been crash-tested in accordance with ANSI/RESNA WC Vol 1

Section 19 Frontal Impact Test requirements for wheelchairs with a 168 lb. crash

dummy, which corresponds to a person with a weight of 114 to 208 lbs.

TRBKTS includes four factory-installed wheelchair transport brackets. TRBKTS has

not been crash-tested in accordance with WC 19. Invacare recommends that these

transport brackets be used only to secure an unoccupied wheelchair during

transport.

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

appropriate 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

wheelchair transportation systems.

Refer to About Transport Ready Packages on page 68 for more information about

transporting the wheelchair.

 TRRO AND TRBKTS WARNING

Only use the transport brackets included with TRRO and TRBKTS for the purposes

described in this manual.

SIGNAL WORD MEANING

DANGER Danger indicates an imminently hazardous situation which,

if not avoided, will result in death or serious injury.

WARNING Warning indicates a potentially hazardous situation which, if

not avoided, could result in death or serious injury.

CAUTION

Caution indicates a potentially hazardous situation which, if

not avoided, may result in property damage or minor injury

or both.

SPECIAL NOTES

Pronto® M91™Base with SureStep® 8Part No 1143153

 WARNINGS

The seat positioning strap is a positioning belt only. It is not designed for use as a

safety device withstanding high stress loads such as auto or aircraft safety belts. If

signs of wear appear, belt must be replaced IMMEDIATELY.

POWERED SEATING SYSTEMS ONLY - This seating system has been custom

designed and will be assembled to the wheelchair base before delivery to the user.

The information contained in this manual is for maintaining and adjusting the

seating system. There are very few adjustments that can safely be made by the user.

If there is a procedure or adjustment that needs to be performed on the seating

system that is not in this manual, do not perform that procedure. Have the seating

system serviced by a qualified technician.

The drive behavior initially experienced by the user may be different from other

chairs previously used. This Power Wheelchair has Invacare’s SureStep technology,

a feature that provides the wheelchair with optimum traction and stability when

driving forward over transitions and thresholds of up to 3-inches. The following

warnings apply specifically to the SureStep Feature.

• DO NOT use on inclines greater than 9°.

• DO NOT use on inclines with wet, slippery, icy or oily surfaces. This may include

certain painted or otherwise treated wood surfaces.

• DO NOT traverse down ramps at high speed. Doing so will reduce traction and

increase stopping distance.

• The end user’s weight can materially affect traction on sloped surfaces. Great

care should be taken when traversing such slopes.

To determine and establish your particular safety limits, practice use of this product

on various sloping surfaces in the presence of a qualified healthcare provider before

attempting active use of this wheelchair. Other general warnings listed within this

document also apply.

Wheelchairs should be examined during maintenance for signs of corrosion (water

exposure, incontinence, etc.). Electrical components damaged by corrosion should

be replaced IMMEDIATELY.

Wheelchairs that are used by incontinent users and/or are frequently exposed to

water may require replacement of electrical components more frequently.

SECTION 2—EMI INFORMATION

 WARNING

CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION

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 wheelchairs) may be susceptible to electromagnetic interference (EMI),

which is interfering electromagnetic 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.

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 exposure 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 elec-

tric shavers and hair dryers, so far as we know, are not likely to cause EMI problems to

your powered wheelchair.

SECTION 2—EMI INFORMATION

Part No 1143153 19 Pronto® M91™Base with SureStep®

 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 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) This device has been tested to a radiated immunity level of 20 volts per meter;

3) The immunity level of the product is unknown.

Modification of any kind to the electronics of this wheelchair as manufactured by

Invacare may adversely affect the EMI immunity levels.

Stability and Balance

 WARNING

ALWAYS wear your seat positioning strap. The seat positioning strap is a

positioning belt ONLY. It is not designed for use as a safety device withstanding high

stress loads such as auto or aircraft safety belts. If signs of wear appear, belt must be

replaced IMMEDIATELY.

DO NOT climb, go up or down ramps or traverse slopes greater than 9°.

Invacare strongly recommends proceeding down ramps or slopes at half speed or

slower and to avoid hard braking or sudden stops.

DO NOT leave elevating legrests in the fully extended position when proceeding

down ramps or slopes.

Be aware that carrying heavy objects on your lap while occupying the wheelchair

may adversely affect the stability of the wheelchair, resulting in serious bodily injury

to the user, damage to the wheelchair and surrounding property.

This wheelchair has been designed to accommodate one individual. If more than

one individual occupies the wheelchair this may adversely affect the stability of the

wheelchair, resulting in serious bodily injury to the user and passenger and damage

to the wheelchair and surrounding property.

Proper positioning is essential for your safety. When reaching, leaning, bending or

bending forward, it is important to use the casters as a tool to maintain stability and

balance.

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.

SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS

Part No 1143153 21 Pronto® M91™Base with SureStep®

 WARNING

Many activities require the wheelchair user to reach, bend and transfer in and out of

the wheelchair. These movements will cause a change to the 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 healthcare

professional BEFORE attempting active use of the wheelchair.

Lifting/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 assistants and

making thorough preparations.

Use ONLY secure, nondetachable parts for hand-hold supports.

It is strongly recommended to lift the wheelchair only by the rear frame and the

front forks - otherwise injury or damage may occur.

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.

The weight of the wheelchair with batteries and without the user is between 203

WARNING

Make sure power to the wheelchair is Off before performing this section.

NEVER allow any of your tools and/or battery cable(s) to contact both battery

terminal(s)/post(s) at the same time. An electrical short may occur and serious

personal injury or damage may occur.

The use of rubber gloves is recommended when working with batteries.

Always use a battery lifting strap when lifting a battery. It is the most convenient

method and assures that the battery acid will not spill. It also helps to prolong the

life of the battery.

DO NOT tip the batteries. Keep the batteries in an upright position.

Avoid storage or use near external flame or combustible products.

Invacare strongly recommends that battery installation and battery replacement

always be done by a qualified technician.

After any adjustments, repair or service and before use, make sure all attaching

hardware is tightened securely - otherwise injury or damage may result.

Battery terminal configuration shown below MUST be used. Batteries that have the

reversed terminal configuration MUST NOT be used - otherwise serious injury or

damage may occur.

CAUTION

When connecting the battery cables to the battery(ies), the battery cable(s) MUST

be connected to the battery terminal(s)/post(s) as shown in FIGURE 9.3 otherwise

damage to the battery may result.

For proper battery connection, batteries MUST use post style terminals with

mounting holes through the terminal.

Charging Batteries

 DANGER

When using an extension cord, use only a three wire extension cord having at least

16 AWG (American Wire Gauge) wire and the same or higher electrical rating as

the devise being connected. Use of improper extension cord could result in a risk of

fire and electric shock. Three prong to two prong adapters should not be used. Use

of three prong adapters can result in improper grounding and present a shock

hazard to the user.

WARNING

Never attempt to recharge the batteries by attaching cables directly to the battery

terminals.

DO NOT attempt to recharge the batteries and operate the wheelchair at the same

time.

DO NOT attempt to recharge the batteries when the wheelchair has been exposed

to ANY type of moisture.

DO NOT attempt to recharge the batteries when the wheelchair is outside.

DO NOT sit in the wheelchair while charging the batteries.

DO NOT attempt to recharge the batteries using both the on-board battery

charger AND an independent battery charger (plugged into the joystick charger

port) at the SAME time. Doing so will reduce the life of the batteries.

READ and CAREFULLY follow the manufactures instructions for each charger

(supplied or purchased). If charging instructions are not supplied, consult a qualified

technician for proper procedures prior to use.

CAUTION

New batteries MUST be fully charged prior to initial use of the wheelchair.

Always fully 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 required charging time. Plan to

recharge them when you do not anticipate using the wheelchair.

Battery Charger Operation

WARNING

READ and CAREFULLY follow the manufacturer’s instructions for each charger

(supplied or purchased). If charging instructions are not supplied, consult a qualified

technician for proper procedures prior to use.

If the circuit breaker trips repeatedly, IMMEDIATELY unplug charger and contact

dealer or a qualified technician.

Three prong to two prong adapters should not be used. Using three prong adapters

can result in improper grounding and present a shock hazard to user.

On-Board Battery Charger

WARNING

Use of improper extension cord could result in risk of fire and electric shock.

When using an extension cord, use only a three wire extension cord having at least

16 AWG (American Wire Gauge) wire and the same or higher electrical rating as

the device being connected.

Ensure the pins of the extension cord plug are the same number, size, and shape as

those on the charger.

DO NOT under any circumstances cut or remove the round grounding plug from

the charger AC cable plug or the extension cord plug.

 WARNING

Contact Invacare Corporation (800-333-6900) with any questions about using this

wheelchair for seating in a motor vehicle.

When feasible, wheelchair occupants should transfer into the vehicle seat and use

the OEM (Original Equipment Manufacturer) vehicle-installed restraint system.

This wheelchair has been dynamically tested in a forward-facing mode with the

specified crash test dummy restrained by BOTH pelvic and shoulder belt(s), and

that BOTH pelvic and upper torso belt(s) should be used to reduce the possibility of

head and chest impacts with vehicle components.

Use ONLY Wheelchair Tie-down and Occupant Restraint Systems (WTORS) which

meet the requirements of the SAE (Society of Automotive Engineers) J2249

Recommended Practice during travel in a motor vehicle.

This wheelchair has been tested for seating in a motor vehicle with the factory

installed seating system ONLY.

This wheelchair MUST be in a forward facing position during travel in a motor

vehicle.

This wheelchair is equipped and has been dynamically tested to rely on

WHEELCHAIR-ANCHORED pelvic belts. If desired, VEHICLE-ANCHORED pelvic

belts may be used.

IT IS STRONGLY RECOMMENDED THAT BOTH PELVIC AND UPPER-TORSO

BELT(S) BE USED TO REDUCE THE RISK OF INJURY.

To reduce the potential of injury to vehicle occupants, wheelchair-mounted

accessories, including but not limited to IV poles, trays, respiratory equipment,

backpacks, and other personal items should be removed and secured separately.

Postural supports, positioning devices, and/or strap(s) should not be relied on for

occupant restraint. These items may be used IN ADDITION TO the wheelchair-

anchored or vehicle-anchored belts.

Wheelchairs with adjustable seat angles MUST be set to 10°.

DO NOT alter or substitute wheelchair frame parts, components, or seating

systems.

A sudden stop and/or collision may structurally damage your wheelchair.

Wheelchairs involved in such incidents should be replaced.

Spill proof batteries, such as “gel cells”, should be installed on wheelchairs to be

used during travel in a motor vehicle.

frontal crash. Steeper angles will reduce

the tendency for a vertical gap to

develop between the user and the belt

due to compliance of seat cushions and

belt movement, thereby reducing the

tendency for the user to slip under the

belt and for the belt to ride up on the

soft abdomen during normal use.

Steeper belt angles also reduce the tendency for upper-torso belts to pull the pelvic

belt onto the abdomen during frontal impact loading.
