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

Wheelchair users should NOT be transported in vehicles of any kind while in
wheelchairs. 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.

SEAT POSITIONING STRAP

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.

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.

SECTION 1—GENERAL GUIDELINES

Anti-Tippers

Anti-tippers are specific to the different seat-to-floor angles and/or seat-to-floor heights.
Refer to the charts in Installing/Adjusting Anti-tippers on page 42 for correct usage and
adjustment. If these requirements cannot be achieved, DO NOT use the wheelchair.
Contact a qualified technician. If changing the seat-to-floor height with or without a
change to seat-to-floor angle, the correct anti-tippers MUST be used to maintain a 1½ to
2-inch ground clearance.

Anti-tippers MUST be fully engaged and release buttons fully protruding out of
adjustment holes.

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.

ALWAYS use anti-tippers. When outdoors on wet, soft ground or on gravel surfaces, anti
tippers may not provide the same level of protection against tipover. Extra caution MUST
be observed when traversing such surfaces.

Operating Information

After ANY adjustments, repair or service and before use, make sure all attaching
hardware is tightened securely - otherwise injury or damage may result.

Unless otherwise noted, all service and adjustment should be performed while the
wheelchair is unoccupied.

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.

When cleaning rear cane or hand grip areas use only a clean towel lightly dampened with
cool water. Verify that grips are dry prior to use. Use of soap or ammonia based cleaning
solutions will result in the hand grips sliding off the cane assembly. Failure to observe this
warning may result in injury to the user or bystanders.

If the wheelchair is exposed to extreme temperature (above 100°F or below 32°F), high
humidity and/or becomes wet, prior to use, ensure that the handgrips DO NOT twist on
the handle. Otherwise, damage or injury may occur.

Avoid storing or using the wheelchair near open flame or combustible products. Serious
injury or damage to property may result.

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

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

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

NEVER leave an unoccupied wheelchair on an incline.

DO NOT operate on roads, streets or highways.

Tracer® IV 10 Part No. 1110558

SECTION 1—GENERAL GUIDELINES

DO NOT attempt to ride over curbs or obstacles. Doing so may cause your wheelchair to
tip over and cause bodily harm to you or damage to 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 behind you, as this may
cause the wheelchair to tip over.

DO NOT shift your weight or sitting position toward direction you are reaching as the

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

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 parallel to the object you are
transferring onto. When transferring to and from the wheelchair, ALWAYS engage both
wheel locks.

DO NOT attempt to lift the wheelchair by 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.

DO NOT stand on the frame of the wheelchair.

DO NOT stand on the footplates. When getting in or out of the wheelchair, make sure that
the footplates are in the upward position or swing the footrests towards the outside of the
wheelchair.

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.

on this wheelchair (you may order with or without the handrims), Invacare strongly
recommends ordering the handrims as an additional safeguard for the wheelchair user.

Part No. 1110558 11 Tracer® IV

SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS

SECTION 2—SAFETY/HANDLING OF
WHEELCHAIRS

Safety/Handling of Wheelchairs

Safety and handling of the wheelchair require 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
heeded. Techniques 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

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.

 WARNING

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.

 WARNING

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.

Tracer® IV 12 Part No. 1110558

SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS

To assure stability and proper operation of your wheelchair, you MUST maintain proper
balance at all times. 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/chest positioning straps for additional
safety while involved in activities that shift your weight.

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 tipping the
wheelchair or traversing curbs, or other impediments.

DO NOT attempt to lift the wheelchair by 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.

If the wheelchair is exposed to extreme temperature (above 100°F or below 32°F), high
humidity and/or becomes wet, prior to use, ensure handgrips DO NOT twist on the
wheelchair’s handle - otherwise damage or injury may occur.

When learning a new assistance technique, have an experienced assistant help you before
attempting it alone.

 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 seat depth, back height/angle, seat angle, size/position of the front casters,
size/position of the rear wheels, anti-tipper model, as well as the user condition
directly relate to the stability of the wheelchair. Any change to one or any combina­tion of the ten may cause the wheelchair to decrease in stability. These adjustments
MUST be performed by a qualified technician.

Part No. 1110558 13 Tracer® IV

SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS

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 healthcare professional before attempting
active use of the wheelchair.

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

Reaching, Leaning and Bending 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.

NOTE: For this procedure, refer to
FIGURE 2.1.

Position the front casters so that they are
extended as far forward as possible and
engage wheel locks.

FIGURE 2.1 Reaching, Leaning and Bending

Reaching and Leaning Backwards

 WARNING

DO NOT lean over the top of the back
upholstery to reach objects behind you,
as this may cause the wheelchair to tip
over.

NOTE: For this procedure, refer to
FIGURE 2.2.

Forward

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.

Tracer® IV 14 Part No. 1110558

FIGURE 2.2 Reaching and Leaning

SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS

Step Tube

Tipping

 WARNING

DO NOT tip the wheelchair without assistance.

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 tipping 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.

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

DO NOT allow the user to leave the wheelchair while the seat is tilted. ALWAYS return
the seat to upright position when transferring the user in or out of the wheelchair.

Method 1 - Wheelchair With Step Tubes

NOTE: For this procedure, refer to FIGURE 2.3.

Place foot on the step tube and begin to tilt the wheelchair toward you. Apply a
continuous downward motion until the balance point is achieved and the front casters
clear the curb. At this point, the assistant will feel a difference in the weight distribution.

 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 forward and slowly
lower the front of the wheelchair in one
continuous movement onto the sidewalk.
Push the wheelchair forward until the rear
wheels roll up and over the curb.

FIGURE 2.3 Method 1 - Wheelchair With

Step Tubes

Method 2 - Wheelchair Without Step Tubes

 WARNING

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

Part No. 1110558 15 Tracer® IV

SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS

NOTE: For this procedure, refer to FIGURE 2.4.

This method requires two 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 stand on the
sidewalk and turn the wheelchair so that
the rear wheels are against the curb. Turn
the anti-tippers so the anti-tip wheels are
pointing up. 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.

FIGURE 2.4 Method 2 - Wheelchair

Without Step Tubes

 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. Turn the anti-tippers so the anti-tip wheels are facing down.

Stairways

 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.

Tracer® IV 16 Part No. 1110558

SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS

 WARNING

Extreme caution is advised when it is necessary to move an occupied 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.

NOTE: For this procedure, refer to FIGURE 2.5.

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

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

2. 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.

3. 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 foot on the next stair and repeats
STEP 1.

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

5. If necessary, rotate the anti-tippers so the wheels are facing down.

FIGURE 2.5 Stairways

Escalators

 WARNING

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

Part No. 1110558 17 Tracer® IV

SECTION 2—SAFETY/HANDLING OF WHEELCHAIRS

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.

Wheelchairs with adjustable height armrests only: Adjust armrests to lowest posi­tion prior to transferring into or out of wheelchair - otherwise injury or damage
may occur.

CAUTION

When transferring, position yourself as far back as possible in the seat. This will help
prevent damaged upholstery and the possibility of the wheelchair tipping forward.

NOTE: For this procedure, refer to FIGURE 2.6.

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

Position the wheelchair as close as possible
alongside the seat to which you are
transferring, with the front casters
pointing parallel to it. Remove or flip up
the armrest. Engage wheel locks. Swing
away or remove front rigging. 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.

FIGURE 2.6 Transferring To and From

Other Seats

Unfolding and Folding Wheelchair

 WARNING

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

DO NOT place hand or fingers on the underside of the seat frame rail when opening
or closing the wheelchair.

DO NOT sit or transfer into the wheelchair unless it is fully open and the seat frame
rails are fully seated into the side frame H-blocks.

Invacare recommends that a non-folding device be installed to keep the wheelchair

Maintenance Safety Precautions

 WARNING

After any adjustments, repair or service and before use, make sure all attaching
hardware is tightened securely. Otherwise injury or damage may result.

CAUTION

DO NOT overtighten hardware attaching to the frame. This could cause damage to
the frame tubing.

Suggested Maintenance Procedures

1. Before using your wheelchair, make sure all nuts and bolts are tight. Check all parts
for damage or wear and replace. Check all parts for proper adjustment.

CAUTION

As with any vehicle, the rear wheels, casters and tires should be checked periodi­cally for cracks and wear, and should be replaced if damaged.

2. The rear wheels, casters and tires should be checked periodically for cracks and wear,
and should be replaced by a qualified technician if damaged.

NOTE: Tire wear is excessive if:

• Pneumatic Tires - there is missing tread or the tires are bald.

• Urethane Tires - there are cuts, surface defects or the tires are loose on the rims.

• Rubber Tires - 30% or more of the tire has worn away.

NOTE: Invacare recommends that tires and casters be replaced every five years.

3. Periodically adjust wheel locks in correlation to tire wear. Refer to Adjusting Patient
Operated Wheel Locks on page 45.

4. Periodically check handrims to ensure they are secured to the rear wheels. If loose,
have them tightened by a qualified technician.

5. Periodically check caster and rear wheel bearings to make sure they are clean and free
from moisture. Use a Teflon® lubricant if necessary.

 WARNING

When cleaning rear cane or hand grip areas use only a clean towel lightly dampened
with cool water. Verify that grips are dry prior to use. Use of soap or ammonia
based cleaning solutions will result in the hand grips sliding off the cane assembly.
Failure to observe this warning may result in injury to the user or bystanders.

Installing/Adjusting Anti-tippers

 WARNING

Anti-tippers are specific to the different seat-to-floor angles and/or seat-to-floor
heights. Refer to the chart in this section of the manual for correct usage and
adjustment. If these requirements cannot be achieved, DO NOT use the
wheelchair. Contact a qualified technician. Any changes to the seat-to-floor angle or
seat-to-floor height may require different anti-tippers.

If so equipped, anti-tippers MUST be attached at all times. Inasmuch as the
anti-tippers are an option for this wheelchair (You may order with or without the
anti-tippers), Invacare strongly recommends ordering the anti-tippers as a
safeguard for the wheelchair user.

Anti-tippers MUST be fully engaged and release buttons fully protruding out of
adjustment holes.

ALWAYS use anti-tippers. When outdoors on wet, soft ground or on gravel
surfaces, anti tippers may not provide the same level of protection against tipover.
Extra caution MUST be observed when traversing such surfaces.

Ensure both anti-tippers are adjusted to the same mounting hole.

NOTE: For this procedure, refer to FIGURE 9.1 on page 43.

Installing Anti-Tippers

NOTE: To ensure the correct model anti-tipper is used refer to Detail “A” in FIGURE 9.1.
Measurements for anti-tippers are approximate and are taken with the extension tube in the bottom
hole position.
