CHAPTER 9: AXLES

Stainless and Titanium Quick-Release Axles

Adjusting

I WARNING
Quick-Release Axles are pre-adjusted to permit minimal "play" in the axle. Permobil Manual recommends that you do not
adjust the axle. Improperly adjusting the axle could cause it to malfunction—too much "play" can cause the axle to bend and
become stuck in the axle sleeve or Zero Play camber tube; too little "play" can prevent the locking balls from engaging fully,
causing the wheel to disengage from the chair without warning. Permobil Manual recommends that an authorized dealer
make any adjustments.
If you ignore this Warning, you may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or
damage the wheelchair.
Tools Needed:
• 19 mm Open End Wrench
• 11 mm Open End Wrench
1. Depress the release button and remove the rear wheel and Quick-Release Axle. See Figures 9-1 and 9-2.
2. Remove the axle from the wheel by depressing the release button and sliding the axle through the rear wheel hub.
3. Once removed from the hub, release the release button (the locking balls should be fully extended).
4. Increase or decrease axle play by adjusting the locknut while securing the opposite end of the axle using the smaller
wrench at the flats at the end of the axle.
5. Depress the release button on the Quick-Release Axle and slide the axle through the rear wheel hub.
6. Depress the release button and reinstall the rear wheel into the axle sleeve or Zero Play camber tube.
7. Before riding in the chair, make sure the locking balls have fully secured the wheel in the axle sleeve or Zero Play
camber tube by pulling on the hub without depressing the release button on the Quick-Release Axle. If the locking balls
do not fully engage, repeat these procedures and increase the play (i.e., increase the distance between the locknut and
the locking balls) to permit the locking balls to fully engage properly. Also, check to make sure there is not too much
play in the axle.
