(TR Series, YG Series, YR Series, ZR Series, Aero Z,
BB and Evo)

Adjusting the Quad Quick Release Handle

WARNING
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 any adjustments be made by an authorized TiLite
dealer. 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 no play in the quad quick release handle, or
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 rear wheel and quick release
axle. See Figure 87.
2. Flip quick release handle to 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 69.
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.
