How to Change the Air Filter in Your Concrete Cut-Off Saw

Gas-Powered Concrete Saws are an important tool that sees heavy usage every day in the construction industry. Like most machinery, these saws require regular maintenance to ensure optimal performance and longevity. A crucial aspect of maintenance that is often overlooked is ensuring the quality of your air filter.

Importance of your Air Filter

The air filter in a concrete saw serves an important purpose in the performance of the saw. The air filter prevents dust, debris and other concrete particles from entering the engine and damaging the internal components of the saw. Without a clean, quality air filter, the dust can clog the engine leading to reduced power, increased fuel consumption, and potential long-term damage to the saw. Ensuring a quality air filter can ensure your saw cuts further, faster and stays off the repair bench.
