DETERMINING TOE IN/TOE OUT (FIGURE 7)
1. Inflate all pneumatic tires to recommended tire pressures (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 (DETAIL "A").
NOTE: For optimum accuracy, perform STEP 2 with the wheelchair occupied.
3. Determine the difference between the two (2) measurements. If the
difference
be-
tween 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
condition exists
(FIGURE 7).
4. If the difference between measurements is not 1/8-inch, correct toe-in/toe-out
condition. Refer to ADJUSTING TOE-IN/TOE-OUT in this procedure of the manual.
