V. SET UP & USE OF YOUR WHEELCHAIR
R. Wheel Installation & Removal
1. Installing Wheels:
a. Push in the axle release button on the axle to allow the
locking 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 (Fig. 28).
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 (Fig. 28).
d. Release the button to lock axle in sleeve. If release but-
ton 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. 29).
2. Adjusting Axles
a. To adjust the axle you will need a 19mm wrench to turn
the outside axle nuts.
b. You will also need an 11mm wrench to hold the ball
bearings on the opposite end of the axle and prevent
the axle from turning.
c. When the wheel is installed, if the axle does not lock,
loosen the axle nut until it locks and axle can move in
and out slightly when locked. If the axle locks, but
moves in and out slightly, proceed to step d.
d. Turn the axle nut counterclockwise until it is tight then
turn the axle nut clockwise 1/3 turn at a time. Check to
see if it is properly adjusted after each 1/3 turn. When properly adjusted there should be no
perceptible movement of the axle in and out in the sleeve, but the axle release button
should be easy to push in.
Review and understand Section R. 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 push button is 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.
