2. Wheel Base Width Adjustment
Adjusting the wheelbase width allows the rider the
option to move the wheels closer or further away from
the hips. This gives the proper wheel spacing to maxi-
mize pushing efficiency.
Adjusting the wheelbase width: (Fig. 10)
a. Loosen the nuts, and reposition the axle sleeve
(A) to the desired width.
b. Retighten nuts.
3. Seat Height Adjustment (Fig. 11)
To adjust the seat height, invert the axle plate and
move vertically to align with the appropriate predrilled
frame holes. Compare figures 9 and 11. Figure 9 repre-
sents the short seat height. Figure 11 represents the
tall seat height. This adjustment allows a 1.5" vertical
seat height adjustment.
NOTE– A new front caster wheel should be used to
correspond with any change in seat height.
4. Rear Wheel Axle Adjustment (Fig. 12)
Tight axle sleeves should be maintained for proper
performance of the wheelchair.
a. To adjust the axle you will need a 5/16" wrench
to turn the outside axle nuts.
b. You will also need a 9/16" wrench to lodge the
ball bearings, on the opposite end of the axle,
and prevent the axle from turning.
c. Turn the outside axle nut counterclockwise
to tighten.
d. There should only be zero to ten thousandths of
an inch (.010") of play.
F. SEAT SLING
The seat sling can be adjusted through the use of
VELCRO® material beneath the seat.
1. Adjustment
a. Remove the screws retaining the left side
seat sling.
b. Readjust VELCRO® material to adjust the tension
in the seat sling.
c. Replace screws.
d. If there is any difficulty in reattaching the screws,
try using a probe to help line up the holes.
G. CUSHION
1. Installation
a. Place cushion on seat sling with VELCRO® material
side down. The beveled edge of the cushion
should be in front.
b. Press firmly into place.
H. REAR AXLES
The most important adjustment on your Quickie wheel-
chair is the position of the rear axle. The center of
gravity, wheel camber and wheelbase are all deter-
mined by the axle adjustment.
Use a torque setting of 100 in.-lbs. when adjusting
rear axle.
1. Center of Gravity (Fig. 9)
Moving the center of gravity to the front will lighten
the force required to turn the chair. The further back
the axle, the more stable the chair becomes.
The center of gravity is adjusted by moving the rear
axle forward or backward on the indexed axle plate.
Moving the axle forward will increase your turning
speed and lighten the front end.
