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 POSITIONING STRAP

Invacare recommends that wheelchair users 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 seat-

ing 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.

AS REGARDS RESTRAINTS - SEAT POSITIONING STRAP - IT IS THE OBLIGATION OF THE

DME DEALER, THERAPISTS AND OTHER HEALTHCARE PROFESSIONALS TO DETERMINE IF

A SEATING RESTRAINT IS REQUIRED TO ENSURE THE SAFE OPERATION OF THIS EQUIP-

MENT BY THE USER. SERIOUS INJURY CAN OCCUR IN THE EVENT OF A FALL FROM A WHEEL-

CHAIR.

TO HEALTHCARE PROFESSIONALS/ASSISTANTS:

The Invacare Orbit wheelchair MUST be operated by a HEALTHCARE professional or assistant

when in ANY tilt position.

ANTERIOR (FORWARD) TILT

Anterior (forward) tilt is a feature of this wheelchair designed for the USE OF A HEALTHCARE

STABILITY

WARNING

The seat height, seat depth, back angle, pivot point of seat frame, seating system, caster position, size and

position of the rear wheels, as well as the user condition directly relate to the stability of the wheelchair. Any

change to one (1) or any combination of the nine (9) may cause the wheelchair to decrease in stability. These

adjustments MUST be performed by a qualified technician.

OPERATING INFORMATION

WARNING

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 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 top of the back upholstery to reach objects from behind as this may cause the wheelchair to tip over.

DO NOT shift your weight or sitting position toward the direction you are reaching as the wheelchair may tip over.

DO NOT tip the wheelchair without assistance.

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

DO NOT attempt to stop a moving wheelchair with the wheel locks. WHEEL LOCKS ARE NOT BRAKES.

Before attempting to transfer in or out of the wheelchair, every precaution should be taken to reduce the gap distance.

Turn both casters toward the object you are transferring onto. When transferring to and from the wheelchair, ALWAYS

ENGAGE BOTH WHEEL LOCKS.

DO NOT operate on roads, streets or highways.

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

o

.

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

DO NOT attempt to ride over curbs or obstacles. Doing so may cause your wheelchair to turn over and cause bodily

harm or damage to the wheelchair.

DO NOT use unauthorized parts, accessories, or adapters other than those authorized by Invacare.

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.

DO NOT stand on the frame of the wheelchair.

Anti-tippers MUST BE attached at all times.

DO NOT use the footplate as a platform when getting in or out 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.

TIRE PRESSURE: DO NOT use your wheelchair unless it has the proper tire pressure (P.S.I.). DO NOT overinflate the tires.

Failure to follow these suggestions may cause the tire to explode and cause bodily harm. The recommended tire

pressure is listed on the side wall of the tire.

Replacement of a tire or tube MUST be performed by a qualified technician.

DO NOT use the release pedal of the tilt mechanism to gain leverage in tipping the wheelchair. The release pedal

was not designed to be used in this manner and may cause injury to the assistant and/or user or damage to the

wheelchair.

WEIGHT TRAINING: Invacare DOES NOT recommend the use of its wheelchairs as a weight training apparatus. Invacare

wheelchairs have NOT been designed or tested as a seat for any kind of weight training. If occupant uses said

wheelchair as a weight training apparatus, Invacare shall NOT be liable for bodily injury and the warranty will be voided

immediately.

WEIGHT LIMITATION: The Orbit wheelchair has a weight limitation of 150 lbs.

SPECIFICATIONS

NOTE: Invacare recommends that rear seat-to-floor height be AT LEAST 3/8-inch shorter than front

seat-to-floor height. Otherwise a forward seat dump can occur. The rear seat-to-floor heights are based

on pneumatic tires or pneumatic tires with flat free inserts. If wheelchair is equipped with urethane tires,

subtract 1/4-inch from the measurements listed above. All heights are approximate to +1/4-inch due to

tire wear and air pressure. The front seat-to-floor heights are approximate to +1/4-inch.

(FIGURES 3, 4 AND 5)

NOTE: Refer to Procedure 1 - General Guidelines

which include GENERAL and SPECIFIC WARNINGS

concerning wheelchair stability.

1. Determine the necessary back position for the

desired seat depth. Refer to FIGURES 4 AND 5

for proper back positioning.

2. If necessary, remove the rear wheels from the

wheelchair. Refer to REMOVING/INSTALLING

THE REAR WHEEL in PROCEDURE 7 of the

owner's manual, part number 1073955.

NOTE: Note the back angle before removing for

proper reinstallation. If a change in the back angle

is desired, refer to CHANGING THE BACK ANGLE

in PROCEDURE 3 of this manual.

3. Remove the two (2) mounting screws, washers

and locknuts that secure the two (2) back angle

plates to the wheelchair frame. Repeat for op-

posite side (FIGURE 3).

4. Align the mounting holes in the back angle plates

with the mounting holes in the rear seat rail de-

termined in STEP 1.

5. Secure the back angle plates to the wheelchair

frame, at the angle noted previously, with the

two (2) mounting screws, washers and locknuts.

Repeat for opposite side. Securely tighten.

NOTE: Make sure the back angle plates are at the

same angle BEFORE using the wheelchair.

STEP 2: Review the chart below to determine the allowable seat frame width and base frame width com-

binations.

WARNING

The seat frame width MUST NOT EXCEED the base frame width by more than 2-inches. Any seat width

greater than 2-inch in relation to the base frame WILL cause the wheelchair to decrease in stability.

These adjustments MUST be performed by a qualified technician.

NOTE: The seat frame and base frame widths are measured in inches.

CHANGING THE WIDTH OF THE TILT-IN-SPACE ORBIT

NOTE: The Orbit wheelchair has a unique feature enabling the user to position a wider seat frame onto a much

narrower base frame or vice versa. The following steps were developed to provide assistance in successfully

determining and changing the orbit into the desired configuration.

STEP 1: Carefully review the following charts and understand the width sizes for the Orbit.

SEAT FRAME WIDTHS

NOTE: SMALL seat frames require one (1) tilt

mechanism.

NOTE: LARGE seat frames require two (2) tilt mechanims.

STEP 3: Determine the statement that corresponds with your desired change. Then, within that

section, determine if a change in the base frame width is desired. Continue to follow

that row all the way over to the right column. This will tell you which sections in this

procedure need to be followed to complete your width change.
