ReAR AxLe (FIG.4.23-4.25)
To Mount and Remove Rear Wheels
WARnInG
•
Do not use this chair UNLESS you are sure both
quick-release axles are locked.
•
An unlocked axle may come off during use and cause
a fall.
•
Axle is not locked until the quick-release button (A)
pops out fully.
To Install Wheel (Fig.4.23)
•
Depress quick-release button (A) fully. This will
release tension on ball bearings at other end.
•
Insert axle through hub of rear wheel (B).
•
Keep pressure on button (A) as you slide axle (C)
into axle sleeve (D).
•
Release button to lock axle in sleeve. Adjust axle if it
does not lock.
•
Repeat steps on other side.
To Remove Wheel (Fig.4.23)
•
Depress quick-release button (A) fully.
•
Remove wheel by sliding axle (C) out of axle sleeve
(D).
•
Repeat steps on other side.
Rear Wheel Axle Adjustment (Fig.4.24)
•
Tight axle sleeves should be maintained for proper
performance of the wheelchair.
•
To adjust the axle you will need a 3/4" wrench (E) to
turn the outside axle nuts (G).
•
You will also need a 1/2" wrench to lodge the ball
bearings (F), on the opposite end of the axle, and
prevent the axle from turning.
•
Turn the outside axle nut clockwise to tighten.
•
There should only be zero to 0.254mm (.010") of
play.
Weight Distribution
Weight distribution between the front and rear wheels is
primarily adjusted by moving the rear axles forward or
rearward on the frame.
•
Moving the axles REARWARD provides better
forward and rearward tipping stability.
•
Moving the axles FORWARD shifts more of the
rider's weight onto the REAR wheels, providing the
following benefits: the front end of the wheelchair
becomes lighter, thus reducing the turning effort, and
with a shorter wheelbase the turning radius is
reduced.
