Determining Toe In/Toe Out - Invacare Top End T-3 Tennis Adjustable Operating And Maintenance Manual

PROCEDURE 6
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 within +1/8-inch, correct toe-in/toe-out
condition. Refer to ADJUSTING TOE-IN/TOE-OUT in this procedure of the manual.
