About the Stihl TS420 Cutquik Cut-Off Saw

The Stihl TS420 Cutquik concrete cut-off saw is so popular among concrete contractors, landscapers, pavers, masons and others, that it could be called the standard in cut-off saws. The TS420 is compact, lightweight, and dependable, proving to be one of the most popular saws on the market.

There are many features the Stihl TS420 is known for, but cutting performance is number one. The TS420 includes a superior air filtration system for an uncontaminated and long-lasting engine.

About Stihl TS420 Air Filters

The Stihl TS420 air filter includes three pieces; the pre-filter, inner filter and the air filter. The OEM part number for the TS420 air filter is 4223-140-4402. DHS Equipment offers value packs in sets of 5 or 10, or you can purchase single air filters.
