CHAPTER 9: AXLES
If the release handle does not flip back and forth from locked to unlocked properly, or if you cannot fully engage it in
the locked position or the unlocked position, the procedure below will permit you to adjust the operation of the handle.
Tools Needed:
• 5/64" 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. Flip the quick-release handle to the locked position.
3. To adjust the "play" between the quick-release handle and the release button inside the quick-release nut: (a)
loosen Set Screw 2 on the quick release nut; (b) rotate the quick-release nut clockwise or counter-clockwise on
the axle until the release button inside the quad quick-release nut just touches the release handle while it is in the
locked position; and (c) tighten Set Screw 2.
4. Adjusting the "play" in the quick-release handle may necessitate an adjustment to the "play" between the collar
and the wheel hub. See "Adjusting the Play" on page 9-3.
5. With the quick-release handle in the unlocked position, reinstall the rear wheel on the chair.
6. Before riding in the chair, make sure the locking balls have fully secured the wheel in the axle sleeve by pulling
on the hub with the release handle in the locked position. If the locking balls do not fully engage, repeat these
procedures to increase the "play" (i.e., increase the distance between the quick-release nut 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. See "Adjusting the Play" on page 9-3.
