- The measurement sensor must be properly adjusted and attached to the vehicle; observe device manufacturer's operating instructions.
- Perform wheel run-out compensation: permissible axial run-out of the wheel rims can exceed the specified toe setting tolerance. If compensation for wheel run-out is not performed, it will not be possible to obtain a correct toe-in adjustment.
- Over time, wheel alignment platforms and computer equipment can lose their original leveling setting and adjustments. They should be calibrated at least once a year as part of the maintenance.
- Handle highly sensitive units with care.
- If necessary, contact the manufacturer for instruction on the proper use of the equipment.
