O. REAR AXLE
1. To Mount and Remove Rear Wheels
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.
NOTE– Axle is not locked until the quick-release button (A) pops out fully.

2. To Install Wheel
a. Depress quick-release button (A) fully. This will release tension on ball bearings at
other end.
b. Insert axle through hub of rear wheel (B).
c. Keep pressure on button (A) as you slide axle (C) into axle sleeve (D).

3. To Remove Wheel
a. Depress quick-release button (A) fully.
b. Remove wheel by sliding axle (C) out of axle sleeve (D).
c. Repeat steps on other side.
4. Rear Wheel Axle Adjustment
Tight axle sleeves should be maintained for proper performance of the wheelchair.
a. To adjust the axle you will need a 3/4" wrench (E) to turn the outside axle nuts (D).
b. 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.
c. Turn the outside axle nut clockwise to tighten.
d. There should only be zero to ten thousandths of an inch (.010") of play.
5. 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, provid-
ing 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.
6. Axle Position Adjustment
a. Remove both wheels from the chair.
b. Remove the bolts (G) from the axle plate (H) on both sides of the chair.
c. Reposition the axle plate in desired position.
d. Insert and tighten bolts (G).
IMPORTANT NOTE– The adjustment on each side of the chair should be exactly equal.
IMPORTANT NOTE– Do not attempt to make this adjustment. This adjustment must be done by an
authorized supplier only.
NOTE– Use a torque setting of 120 in.-lbs. When setting-up the axle plate.
7. Axle Height Adjustment
a. Loosen and remove bolts (G).
b. Set axle at desired height using pre-set holes in the axle plate (H) on both sides.
c. Replace and tighten bolts.
IMPORTANT NOTE– The adjustment on each side of the chair should be exactly equal.
IMPORTANT NOTE– Do not attempt to make this adjustment. This adjustment must be done by an
authorized supplier only.
