# Intended Use

The class of user a saw is built for: consumer, semi-professional or professional. It summarises the duty cycle the machine is designed to sustain rather than any single technical measurement.

The classes differ in things that rarely appear as numbers: bearing quality, air filtration, ease of field service, magnesium versus polymer crankcases and the expected hours before a rebuild. A consumer saw used occasionally on firewood may outlast a professional one used daily, so the class describes intensity of use rather than quality in the abstract. Buying above your class is mostly a question of paying for durability you will not consume; buying below it shows up as overheating, premature wear and frustration. Match the class to hours per year first, then look at **Engine Displacement** and **Weight**.
