Dual Dimensions
This shop manual provides specifications in both Metric (SI) and U.S. Customary systems of measurement. The primary specification is given in the system perceived as preferred for servicing a particular component. The secondary specification, enclosed in parentheses, is the converted equivalent. For example, a specification of "0.28 mm (0.011 inch)" would indicate that the metric measurement is preferred, with the U.S. Customary equivalent provided for reference.
