How to Replace the Air Filter on a Makita Cut-Off Saw Model DPC7311

If engine rust and concrete dust are cutting into your construction budget, it's time to face the fix. Whether you are a master mason or a backyard builder, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.

Because of the amount of dust and debris generated by this type of saw, a clean air filter is critical to ensuring optimum engine performance and longevity.

Although the manufacturer recommends routine intervals for replacement, the air filter should be inspected frequently, and replaced at the first sign of damage or deterioration. Heavy use conditions (such as using the saw to cut concrete without the water system attached) will necessitate more frequent filter replacement.

The air filter can typically be cleaned several times before it actually needs to be replaced. Often, cleaning the filter is as simple as tapping it against any hard surface to remove heavier deposits of dust and debris. Compressed air may also be used (carefully) to blow debris out of the paper pleats.

A thorough inspection should be performed each time the air filter is removed for cleaning. If any part of the filter is found to be damaged, it will need to be replaced. This article will show you how to quickly remove, inspect, clean and/or replace the air filter in your Makita DPC7311 (Power Cutter) cut-off saw.
