4 SAFETY/HANDLING OF WHEELCHAIRS

4 Safety/Handling of Wheelchairs

4.1 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

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.

4.2 Stability and Balance

WARNING

ALWAYS wear your seat positioning strap. Inasmuch as the seat positioning strap is an option on this wheelchair (you may

order with or without the seat positioning strap), Invacare strongly recommends ordering the seat positioning strap as an

additional safeguard for the wheelchair user. 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 attempt to lift a wheelchair by lifting on any removable (detachable) parts. Lifting by means of any removable

(detachable) parts of the wheelchair may result in injury to the user or damage to the wheelchair.

ALWAYS check hand grips for looseness before using the wheelchair. If loose and/or worn, replace IMMEDIATELY.

Anti-tippers MUST be attached at all times. Inasmuch as the anti-tippers are an option on this wheelchair (you may order

with or without the anti-tippers), Invacare strongly recommends ordering the anti-tippers as an additional safeguard for the

wheelchair user.

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

4 SAFETY/HANDLING OF WHEELCHAIRS

WARNING

Invacare strongly recommends proceeding down ramps or slopes slowly to avoid hard braking or sudden stops.

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

the wheelchair and surrounding property.

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.

Virtually all activities which involve movement in the wheelchair have an effect on the center of gravity. Invacare recommends using seat positioning

straps for additional safety while involved in activities that shift your weight.

DO NOT lean forward out of the wheelchair any further than stability will allow. Make sure 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.

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.

The position of the footrest, camber tube, back angle, the tautness of the back upholstery as well as the user's condition are

directly related to the wheelchair's stability. Any change to one or any combination of the five may cause the wheelchair to

decrease in stability. Use EXTREME caution when using a new seating position. The addition of anti-tippers may be

required.

Many activities require the wheelchair owner to reach, bend and transfer in and out of the wheelchair. These movements will cause a change to the

normal balance, the center of gravity, and the 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-care professional before attempting active use of wheelchair.

Proper positioning is essential for your safety. When reaching, leaning, bending forward, it is important to use the front casters as a tool to maintain

stability and balance.

4.3 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.

4.4 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.

WARNING

Do not attempt to lift a wheelchair by lifting on 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.

Download from Www.Somanuals.com. All Manuals Search And Download.

4 SAFETY/HANDLING OF WHEELCHAIRS

Also, be aware of any removable (detachable) parts. 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.

4.5 Tipping

WARNING

DO NOT tip the wheelchair without assistance

Do not let the wheelchair drop the last few inches to the ground. This could result in injury to the occupant.

When tipping the wheelchair, an assistant should grasp the back of the wheelchair on a non-removable (non-detachable) 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 and/or pinch points. Apply a continuous motion until the balance point is achieved. At this point, the assistant will feel a difference in

the weight distribution. Turn the wheelchair in the desired direction if necessary. Slowly lower the wheelchair in one continuous movement.

Tipping - Curbs

WARNING

Invacare does not recommend that sport wheelchairs be used where traversing curbs present an obstacle. Possible injury

to occupant and/or assistant(s) can occur. Transfer to an everyday use wheelchair is recommended if any such obstacles

may be encountered.

After mastering the techniques of tipping the wheelchair, use the following method to tackle curbs, short stairs, etc.

Turn the anti-tippers, if equipped, so the wheels are facing UP. Unless the first assistant has exceptional upper body strength, it is recommended that two

assistants perform this operation. 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 stand on the sidewalk and turn the wheelchair so that the rear wheels are against the curb. The wheelchair should be tilted

back to the balance point and, in one continuous upward movement, the rear wheels should be pulled up and over the curb. DO NOT return the

front casters to the ground until the wheelchair has been pulled backward far enough for the front casters to clear the edge of the curb.

4 SAFETY/HANDLING OF WHEELCHAIRS

WARNING

When lowering the front casters of the wheelchair,

Do not let the wheelchair drop the last few inches

to the ground. This could result in injury to the

occupant and/or damage to the wheelchair.

Roll the wheelchair backward 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. Turn

the anti-tippers so the wheels are facing down.

FIGURE 3 Tipping - Curbs

4.6 Stairways

WARNING

Extreme caution is advised when it is necessary to move an occupied or unoccupied wheelchair up or down the stairs.

Invacare recommends that, if possible, the user be removed from the wheelchair prior to moving. Invacare

recommends using two assistants and making thorough preparations. Make sure to use only secure, non-detachable

parts for hand-held supports.

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

Moving Up Stairs

1. If necessary, rotate the anti-tippers so the wheels are facing up.

2. One assistant (positioned behind the wheelchair), securely grasps a non-removable (non-detachable) part of the wheelchair for leverage and tilts

the wheelchair back to the balance point.

3. After the wheelchair has been tilted back to the balance point, the assistant behind the wheelchair backs the wheelchair up against the first step.

4. The second assistant (positioned in the front of the wheelchair), with a firm hold on a non-detachable part of the framework, lifts the wheelchair

up and on to the next stair above and steadies the wheelchair as the assistant behind the wheelchair places one foot on the next stair above and

repeats process.

4.7 Escalators

WARNING

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

4.8 Transferring To and 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 parallel to the object you are transferring onto. Also be certain the wheel locks are engaged to help

prevent the wheels from moving.

When transferring, position yourself as far back as possible in the seat. This will prevent damaged upholstery and the

possibility of the wheelchair tipping forward.

This activity may be performed independently

provided you have adequate mobility and upper

body strength.



Position the wheelchair as close as possible along side the seat to which you

are transferring, with the front casters parallel to it. Remove the armrest, if

installed. 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.

After ANY adjustments, repair or service and BEFORE use, make sure all attaching hardware is tightened securely -

otherwise injury or damage may occur.

8.1 Unfolding/Folding the Back

WARNING

After unfolding the back, ensure that the plunger pins are fully engaged in the mounting holes of the adjustment square in

the back cane mounting brackets (Detail “C” in FIGURE 1). Back MUST be locked securely in place. Otherwise, serious

injury could result.

For this procedure, refer to FIGURE 1 on page 44.



1. To fold the back, pull up on the back release cord and push the back toward the seat of the wheelchair (Detail “A”).

2. To unfold the back, pull up on the back release cord and lift the back away from the seat until the back locks into place (Detail “B” and Detail “C”).

An audible “click” will be heard when the plunger pins fully engage into the adjustment square (Detail “C”) and the split ring

will be flush up against the back stop insert.



The back should have a small amount of movement when locked in the open position. Plunger pins should snap in and

release easily without resistance.

8.2 Back Angle Adjustment

For this procedure, refer to FIGURE 2 on page 47, F IGURE 3 on page 48, FIGURE 4 on page 49, and FIGURE 5 on page 50.



The numbers in the recess of the back angle plate are intended to define the resulting back angle of a chair that has 2 inch

seat drop (at 17 inch depth) and that is measured relative to true vertical with the chair sitting on a level surface. The plus

(+) sign increases the back angle and the minus (-) sign decreases the back angle. The resulting back angle will vary

somewhat depending on your chair configuration. Refer to FIGURE 3 on page 48 to see these settings converted into back

angle relative to the seat.

Perform this procedure on both sides of the wheelchair at the same time.

1. Fold down the back. Refer to Unfolding/Folding the Back on page 43.

2. Loosen the jam nut on the placement screw located at the bottom of the back cane (Detail “A”).

3. Tighten the placement screw so that the screw and jam nut are snug against the bottom of the back cane (Detail “B”).

4. Remove the mounting screw that secures the adjustment square to the back angle plate (Details “A” and“C”).

5. Remove the adjustment square from the recess of the back angle plate (Detail “C”).

Note the hole on the adjustment square. When the hole is positioned on top of the number inside the recess, this number

represents the back angle relative to true vertical. One side of the adjustment square provides back angles of -8°, 0° and -4°.



Flip the adjustment square over to obtain back angles of 8°, 4° and 0° (FIGURE 3).

WARNING

If the adjustment square is installed into the recess of the back angle plate so that the adjustment square hole is not on top

of a number, DO NOT use this position. Otherwise, injury will occur. When the adjustment square hole is not on top of a

number, it prevents the locking pins from locking into position when the back is raised.

6. Position the adjustment square in the recess of the back plate with the hole located aligned with a number (FIGURE 3).

7. Secure the adjustment square to the back angle plate with the mounting screw. Tighten securely.
