I know more than one person who has ruined an expensive 2-stroke machine by accidentally fueling it with straight gasoline (instead of the required gas/oil mixture). That can’t happen with Makita’s new EK7651H power cutter because its 4-stroke engine uses regular unleaded gasoline.

The Makita machine takes a 14-inch blade and is designed for wet and dry cutting in material such as concrete, steel, and masonry. According to its maker, this cutter runs quieter, idles smoother, and is more efficient than comparable machines. Innovative features include automatic decompression (to reduce pull-starting force) and a wheel kit that retracts when not in use. The video below was shot at The World of Concrete.
