Invacare T6 manual Determining Toe In/Toe Out

SECTION 8—WHEELS

Determining Toe In/Toe Out

NOTE: For this procedure, refer to FIGURE 8.13.

1.Inflate all pneumatic tyres to recommended tyre pressures (listed on the sidewall of the tyre).

2.Measure the distance between the centerlines at the rear and front of the rear wheels at approximately 12 inches (30.48 cm) from the ground/floor (FIGURE 8.13).

NOTE: For optimum accuracy, perform STEP 2 with the wheelchair occupied.

3.Determine difference between two measurements. If difference between the two measurements is greater than ½-inch (1.27 cm) (0 + ¼-inch (.64 cm) for maximum rollability), one of two conditions exists:

•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 8.13).

•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 8.13).

4.If the difference between the measurements is greater than ½-inch (1.27 cm), correct the toe-in/toe-out condition.
