V. SET UP & USE OF YOUR WHEELCHAIR
O. Wheel Installation & Removal
1.
Installing Wheels (Fig. 19)
a. Push in the axle release button on the axle to allow the lock-
ing balls to retract. Make note of the difference between the
extended and depressed position of the axle release button
and its effect on the locking balls on the other end of the
axle.
b. Insert the axle into the bearing housing on the wheel if it's
separate.
c. Push on quick release button again and slide axle into axle
sleeve.
d. Release the button to lock axle in sleeve. If release button
does not fully extend and the locking balls do not move into
the locked position after releasing the button, the axle length
needs to be adjusted (Fig. 20).
2. Adjusting Axles
a. To adjust the axle you will need a 19mm wrench to turn the
adjustment nut. You will also need an 11mm wrench to securely hold the ball detent end of
the axle to prevent it from turning.
b. If the wheel and axle will not lock into the camber adapter, the axle requires adjustment.
Turn the nut counterclockwise approximately ¼ revolution and try to lock the axle into the
camber plug. If it doesn't lock, continue making small nut adjustments until it securely locks.
c. If the wheel is locked on the chair but there is excessive wheel play (the wheel hub can be
pushed back and forth on the axle), then adjust the nut clockwise until there is no percepti-
ble gap between the wheel and camber tube and the axle is securely locked onto the chair.
Review and understand Section O. Wheel Installation & Removal before attempting an axle
adjustment!
3. Removing Wheels
a. Hold the wheel close to the hub and push in the button on the outside end of the axle.
b. While still holding the button, pull the wheel and axle out of the axle sleeve.
DANGER: Make sure the axle push buttons are completely extended and the locking balls on
the inside of the chair are fully engaged before operating the wheelchair. Failure to do so may
result in the wheel falling off and may cause serious injury or death.
