Makita launches first 4-stroke disc cutter
By Sarah Ann McCay12 November 2012
Power tool manufacturer Makita has introduced the world’s first 4-stroke 12-inch disc cutter.
The Makita EK7650H 4-stroke 76 cc engine delivers 4 hp with low noise output and fuel consumption.
The new Makita MM4 engine has the attributes of 4-strokes with lower engine vibrations than a 2-stroke equivalent. The EK7650H uses a vibration damping system to effectively isolate the motor and drive system from the chassis, to reduce the effect to the operator of the HAV (hand arm vibration) risks. The Makita EH7650H has the lowest vibration ratings of all competitive 2-stroke brands, claimed the company.
The 12-inch blade can run at up to 4300 rpm and gives a 97 mm maximum depth of cut.
The Makita EK7650H is equipped with an in-built water dust suppression system, with an air intake and air cleaner at the very top of the engine, in the cleanest zone.
The 4-stroke unit, which weighs 12 kg, also has an automatic decompression that reduces the pull cord effort by 40% and rapid start spring-assisted recoil starting. Other easy start functions include an on-off choke combination switch.
