New EK7651H gives contractors convenience, faster starts, improved fuel economy, and more

La Mirada, CA – Makita has created the world’s first 4-stroke engine power cutter, the 14" MM4™ 4-Stroke Power Cutter (model EK7651H). The EK7651H is the latest innovation in Makita’s extensive range of concrete solutions.

"Engine seizure due to improper fuel and oil mixing is one of the most common failures of 2-stroke commercial power cutters," said Adam Livingston, Product Manager, Commercial Products. "Makita has changed the game and delivered the solution with the development of the world’s first 4-stroke engine power cutter. This latest innovation from Makita goes beyond exceptional tool performance, as users will now need only one gas can for all their power equipment."
Makita applied years of research into the development of the EK7651H power cutter to solve the most common user pains including fuel mixing, but also start-up’s, fuel economy, ease-of-use during long cuts, and more.  
"This new 4-stroke engine power cutter runs quieter, idles smoother and is more fuel efficient," said Livingston. "It also has several other innovative features including automatic decompression which reduces pull-starting force by up to 40%, and an all-aluminum integrated wheel kit that retracts when not in use."  
Makita 4-Stroke Advantage
The new 4-stroke engine EK7651H delivers several advantages over 2-stroke: 
  • No oil mixing offers simplified operation and prevents engine failure due to improper mix
  • Eliminates the need for separate mixed oil/fuel can
  • Lower noise at 92.7 dB(A) and smoother idle for continuous operation
  • Lower fuel consumption at .45 gallons per hour
  • Reduced exhaust and intake carbon build-up for long cylinder life
  • Three-ring piston for improved commercial engine durability
Power and Performance for Demanding Applications
The EK7651H has a 4.6 (75.6 cc) engine with 4.1 HP (maximum horsepower) and a no load speed of 9,350 RPM to take on the most demanding applications. The automatic engine decompression valve is engineered into the cam gear to reduce pull start force by 40% for easier starts. In addition, the pressure-compensating carburetor with vented choke plate is engineered to reduce flooding by automatically adjusting to deliver the proper amount of fuel. For increased ease-of-use and maintenance, the EK7651H has a five-stage foam-paper-nylon filtration system with Advance Direction Air Flow to provide cleaner air to the engine for improved engine durability. 
The power and performance features of the EK7651H make it a best-in-class 14" power cutter for a range of professional concrete cutting applications and is ideal for landscapers, road construction crews, railroad crews, rescue crews, general steel contractors, masons, and welders. 
"The conversation is no longer about slightly more power or a little less weight, it is now about how much this new jobsite solution can save in run costs, repair and maintenance expenses, and productivity," said Livingston. "The future of power cutters is now, and the EK7651H is in a class by itself."
