

WARNING

STAIRWAYS AND ESCALATORS

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. Make sure to use ONLY secure, non-detachable parts for hand-hold supports.

DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury 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 without the user and without batteries is between 203 and 318 lbs. Use proper lifting techniques (lift with your legs) to avoid injury.

Wheelchair users: DO NOT service or operate this equipment without first reading and understanding (1)the owner’s operator and maintenance manual and (2) the seating system’s manual (if applicable). If you are unable to understand the warnings, cautions, and instructions, contact Invacare technical support before attempting to service or operate this equipment - otherwise injury or damage may result.

Dealers and qualified technicians: DO NOT service or operate this equipment without first reading and understanding (1) the owner’s operator and maintenance manual, (2) the service manual (if applicable) and (3) the seating system’s manual (if applicable). if you are unable to understand the warnings, cautions and instructions, contact Invacare technical support before attempting to service or operate this equipment - otherwise, injury or damage may result.

2.2 Safety/Handling

“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. Users and assistants must be aware that the handling and maneuverability characteristics of center wheel drive wheelchairs are inherently different

from front and rear wheel drive wheelchairs. Handling and maneuverability differences will be most noticeable when traveling down declines (Example: ramps and slopes) or over obstacles and rough terrain as this may shift the users center of mass forward resulting in decreased stability. ALWAYS reduce speed and wear the seat positioning strap when driving under these conditions.

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 warnings and cautions given in this manual MUST be followed. Techniques in this manual are a starting point for the new wheelchair user and assistant with “safety” as the most important consideration for all.

Invacare strongly recommends that initial use of center wheel drive wheelchairs be supervised by an assistant.



WARNING

The seat positioning strap is a positioning strap 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, strap MUST be replaced IMMEDIATELY.

DO NOT leave the power button On when entering or exiting your wheelchair.

DO NOT go UP or DOWN ramps or traverse slopes greater than 9°.

NEVER leave an unoccupied wheelchair unattended on an incline.

DO NOT attempt to move up or down an incline with water, ice or oil film.

DO determine and establish your particular safety limits by practicing bending, reaching and transferring activities in the presence of a qualified healthcare professional before attempting active use of the wheelchair.

DO NOT attempt to reach objects if you have to move forward in your seat.

2 SAFETY

Part No 1143153

21 Invacare® Pronto® M91™

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 to move the wheelchair or as 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.



WARNING

ALWAYS shift your weight in the direction you are turning. DO NOT shift your weight in the opposite direction of the turn. Shifting your weight in the opposite direction of the turn may cause the inside drive wheel to lose traction and the wheelchair to tip over.

DO NOT make sharp turns in the forward or reverse directions at excessive speed. Failure to observe this warning can cause the wheelchair to tip over and may result in injury to users, bystanders and/or damage to product.

DO NOT shift your weight or sitting position toward the direction you are reaching as the wheelchair and/or seating system (if any) may tip over.

ALWAYS keep hands and fingers clear of moving parts to avoid injury.

DO NOT use with a broken or missing joystick knob.

DO NOT use if joystick does not spring back to the neutral position or becomes sticky or sluggish.

DO NOT use if joystick boot is torn or damaged.

DO NOT store items under seat - interference with seat latch may result.

ALWAYS check foam grips for looseness before using the wheelchair. If loose, contact a qualified technician for instructions.

DO NOT attempt to stop a moving wheelchair with the wheel locks. Wheel locks are not brakes.

DO NOT engage or disengage the motor locks until the power is in the off position.

ALWAYS wear your seat positioning strap. The seat positioning strap is a positioning strap ONLY. It is not designed for use as a safety device withstanding high stress loads such as auto or aircraft safety straps. If signs of wear appear, strap MUST be replaced IMMEDIATELY.

With regards to seat/chest positioning straps - it is the obligation of the DME dealer, therapists and other healthcare professionals to determine if a seat/chest 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.

The drive behavior initially experienced by the user may be different from other wheelchairs previously used. This 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.

• ALWAYS traverse down ramps at a reduced, constant speed to maintain stability and to avoid hard braking or sudden stops.

• The end user’s weight can materially affect traction on sloped surfaces. Great care should be taken when traversing such slopes.

ALWAYS reduce speed when traveling up or down an incline or over obstacles and rough terrain. Traveling under these conditions may shift the users weight forward resulting in reduced stability.

To assure stability and proper operation of your wheelchair, you must at all times maintain proper balance. Your 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.



WARNING

Exercise caution and avoid sudden stops when traveling up or down an incline or over obstacles and rough terrain. If stopping becomes necessary under these driving conditions, release the joystick and allow the wheelchair to come to a full stop. Then proceed at a slower speed.

DO NOT leave elevating legrests in the fully extended position when proceeding down ramps or 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.

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.

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.

DO NOT stand on the frame of the wheelchair.

DO NOT adjust the rear seat posts higher than the front seat posts.

Coping with Everyday Obstacles

Coping with the irritation of everyday obstacles can be somewhat alleviated by learning how to manage your wheelchair. Keep in mind your center of gravity to maintain stability and balance.

While the walking beam allows to traverse up to a 3 inch bump or threshold, stopping after the wheels cross the bump poses a problem. the wheelchair cannot reverse over the bump at this point. Continue forward and then turn around.

While the wheelchair is designed for use primarily in and around the home, the provider should determine whether this wheelchair is suitable for the actual environment in which the wheelchair will be used.

FIGURE1 Coping with Everyday Obstacles



WARNING

DO NOT attempt to drive over curbs or obstacles greater than 3 inches. Doing so may cause your wheelchair to turn over and cause bodily harm or damage to the wheelchair. Always stop before climbing an obstacle. Approach slowly until front casters are approximately 18 inches away from the obstacle. Slowly apply power to move forward, over the obstacle.

CAUTION

Be aware of the condition of the ramp. Traction will be diminished/nonexistent on a slippery surface. Proceed with caution.



For this procedure, refer to FIGURE1.

Do not go down a ramp at full speed. Some seat/ back positions will cause the wheelchair to feel unstable.

Footplates and Front Rigging



WARNING

If the wheelchair dips forward and the footplates touch the ground while the wheelchair is in motion, please contact your dealer for an inspection and avoid use of the wheelchair if possible. Otherwise the user could be injured.

ALWAYS maintain a minimum of 3-inches between bottom of the front riggings and the floor/ground while the wheelchair is in motion to ensure proper ground clearance. If necessary, adjust the front rigging height or tilt seat to achieve proper ground clearance.

When determining the depth of the telescoping front frame tubes, make sure the rear of the footrests DO NOT interfere with the movement of the front casters. Otherwise damage to the wheelchair may result or may impede proper operation.

DO NOT use the footplates/footboard 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.

Make sure detent balls of the quick-release pin are fully released before operating the wheelchair. Keep detent balls clean.
