WARNING
Quad quick-release axles are pre-adjusted to permit minimal “play” in the axle. TiLite 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; too little “play” can prevent the locking balls from engaging fully, causing the wheel to
disengage from the chair without warning. TiLite recommends that an authorized TiLite 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 too little “play” so
the locking balls do not properly engage, follow this procedure:
1. Flip the quick-release handle to the unlocked position and remove the rear wheel and the quad quick-release axle. See
Figure 9-2, 9-3 and 9-4.
2. Adjust Set Screw 3 on the quad 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, securely tighten Set Screw 1 so the collar is securely on the axle sleeve.
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 counter-
clockwise 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 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.

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.
