Adjusting The "Play - Permobil Aero Z 2 Series Owner's Manual

CHAPTER 9: AXLES
I WARNING
The threads on the set screws on the Quad Quick-Release Axles assemblies are treated with Loctite
strength thread lock. If you loosen any set screw, you MUST remove and reapply Loctite
strength thread lock.
If you ignore this Warning, your rear wheel could become loose or fall off and you could fall, tip over or lose control of the
wheelchair and seriously injure yourself or others or damage the wheelchair.

Adjusting the "Play"

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.
If there is too much "play" in the axle so the wheel is loose when locked into position in the axle sleeve or Zero Play camber
tube or too little "play" so the locking balls do not properly engage, follow this procedure:
Tools Needed:
• 2 mm Allen Wrench
1. Flip the quick-release handle to the unlocked position and remove the rear wheel and Quick-Release Axle.
See Figures 9-3 and 9-4.
2. Adjust Set Screw 3 on the quick-release nut so that no portion of Set Screw 3 is protruding out of the opposite side
of the quick-release nut (the side adjacent to the wheel hub).
3. Loosen Set Screw 1 on the collar.
4. Replace the wheel on the chair.
5. With the wheel still on the chair and the quad quick-release handle in the locked position so the locking balls are fully
engaged, be sure the collar is snug against the outer rear wheel bearing and securely tighten Set Screw 1 so the collar
is securely on the axle.
6. With the release handle in the unlocked position, turn Set Screw 3 clockwise to remove any remaining play between the
wheel hub and collar.
7. Flip the quad quick-release handle to the locked position and check the "play" in the axle. Make sure the locking balls
fully engage and lock the axle into the camber tube. If there is still too much "play" in the axle, repeat the procedure
in Step 6. If you have taken too much "play" out of the axle, repeat the procedure in Step 6, but turn Set Screw 3
counterclockwise to add "play" to the axle.
8. Before riding in the chair, check the "play" in the wheel and check to make sure the locking balls have fully secured the
axle inside the axle sleeve or Zero Play camber tube by pulling on the hub with the quad quick-release handle in the
locked position. If the locking balls do not properly engage or there is too much "play", return to Step 1 and repeat this
procedure.
I WARNING
The threads on the set screws on the Quad Quick-Release Axle assemblies are treated with Loctite
thread lock. If you loosen any set screw, you MUST remove and reapply Loctite
thread lock.
If you ignore this Warning, your rear wheel could become loose or fall off and you could fall, tip over or lose control of the
wheelchair and seriously injure yourself or others or damage the wheelchair.
