SECTION 8—WHEELS

Part No 1148078 49 Crossfire™Series Wheelchairs

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.
