Technology

MM4® 4-Stroke Engine
Engine seizure due to improper fuel and oil mixing is one of the most common failures of 2-stroke power equipment. Makita has a solution with efficient MM4® 4-stroke engine power equipment. The Makita MM4® 4-stroke advantage means no more fuel mixing for simplified operation and no need for a separate mixed oil-fuel can. In addition, Makita MM4® 4-stroke engines are engineered for lower noise, improved fuel economy, reduced exhaust, and faster, easier starts for increased efficiency. MM4® 4-stroke power equipment includes a concrete power cutter as well as blowers, hedge trimmers, string trimmers, pole pruners, and more.
