SECTION 5-WHEELS ƽ WARNING NEVER position the camber inserts in the axle tube with more than 3-inches (7.62 cm) (12 indexing marks showing) of the camber insert outside of the axle tube. The camber inserts will not be securely tightened in the axle tube. Possible injury to the user and/or damage to the wheelchair may occur. 6. Position the camber insert to the desired position. Make sure there is no more than 3 inches (7.62 cm) (12 indexing marks) of the camber inserts outside of the axle tube. 7. Slide the indexing ring on the camber insert until it is flush with the camber clamp. NOTE: Before using the wheelchair, make sure both camber inserts are set to the same indexing mark. This will make sure the distance between the rear wheel and the wheelchair is the same on both sides. 8. Close the camber clamp. Refer to Opening/Closing Camber Clamps on page 34. 9. Repeat STEPS 1‐8 for opposite side of wheelchair. 10. Reinstall rear wheel to the wheelchair. Refer to Removing/Installing Rear Wheels on page 32. 11. Adjust toe in/toe out of wheelchair. Refer to Adjusting Toe In/Toe Out on page 37. Determining Toe In/Toe Out NOTE: For this procedure, refer to FIGURE 5.8 on page 36. 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 5.8). 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 1/2‐inch (1.27 cm) (0 + 1/4‐inch (.63 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 5.8). • 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 5.8). 4. If the difference between the measurements is greater than 1/2‐inch (1.27 cm), correct the toe‐in/toe‐out condition. Refer to Adjusting Toe In/Toe Out on page 37.
