REPAIRING/REPLACING REAR WHEEL TIRE/ TUBE

WARNING

Replacement of a rear wheel tire or tube MUST be performed by an authorized Invacare dealer or quali- fied technician.

ADJUSTING THE WHEELBASE LENGTH (FIGURE 8)

WARNING

The seat height, seat depth, back angle, seating sys- tem, 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 combi- nation of the seven (7) may cause the wheelchair to decrease in stability. These adjustments MUST be performed by an authorized dealer or qualified tech- nician.

RECLINERS ONLY: Before using ANY recline position of this wheelchair, make sure the rear wheels are in the MOST REARWARD position in the Extended Multi-Position axle plate to main- tain the stability of the wheelchair. Do not change the handling/maneuverability of the wheelchair by moving the rear wheels to ANY of the forward positions. Moving the rear wheels to ANY of the forward positions WILL change the center of grav- ity of the wheelchair, making the wheelchair less stable.

WARNING

Wheel locks MUST be adjusted BEFORE using the wheelchair.

Anti-tippers, if equipped, MUST be repositioned BEFORE using the wheelchair.

Lengthening the Wheelbase will increase stability and maintain standard maneuverability of the wheelchair.

Shortening the Wheelbase will increase maneuverabil- ity and distribute additional weight onto the rear wheels.

Centering the Wheelbase gives you maneuverability and stability.

1.Remove the rear wheel from the wheelchair. Refer to REMOVING/INSTALLING REAR WHEELS in this section of the manual.

2.Loosen the two (2) jam nuts that secure the axle bush- ing to the axle mounting plate.

3.Move the axle bushing forward or rearward to the desired position.

4.Securely tighten the jam nuts that secure the axle bushing to the axle mounting plate.

5.Reinstall the rear wheel onto the wheelchair. Refer to REMOVING/INSTALLING REAR WHEELS in this section of the manual.

6.Repeat STEPS 1-5for the opposite side of the wheel- chair.
