DETERMINING TOE IN/TOE OUT
(FIGURE 7)
1. Inflate all pneumatic tires to recommended tire pres-
sures (listed on the sidewall of the tire).
2. Measure the distance between the centerlines at the
rear and front of the rear wheels at approximately
12-inches from the ground/floor (FIGURE 7).
NOTE: For optimum accuracy, perform STEP 2 with the
wheelchair occupied.
3. Determine the difference between the two (2) mea-
surements. If the difference between the two (2)
measurements is NOT within +1/8-inch, one (1) of
two (2) conditions exists:
A. If the back centerline measurement of the rear
wheels is SMALLER than the front centerline
measurement of the rear wheels, a TOE-OUT
condition exists (FIGURE 7).
B. If the back centerline measurement of the rear
wheels is LARGER than the front centerline
measurement of the rear wheels, a TOE-IN con-
dition exists (FIGURE 7).

Axle Tube Positioning For 0°/3°, 0°/6°, 3°/6°
or 9°/12° Camber Inserts (FIGURE 8)
CAUTION
DO NOT rotate the axle tube if the axle tube is
locked out by the toe adjustment rings. If a locked
out axle tube is rotated, damage to the toe ad-
justment rings will occur.
NOTE: Refer to FIGURE 8 for a description of a locked
out axle tube.
There is NO adjustment required to maintain a cor-
rect toe in/toe out measurement.
NOTE: The axle tube will be locked out by the toe adjust-
ment rings and will NOT rotate.
