The Makita MM4 4-Stroke Engine Mist Blower is equipped with a 75.6 cc 3.67 HP commercial-duty engine for efficient spray dispersion. The MM4 4-stroke engine runs on straight gas and requires no fuel mixing. At 3.9 gallons, the PM7650H has the largest chemical tank capacity in the category. The PM7650H has a single-action on/off switch to activate liquid chemical flow, with a spray range of 52 ft. (horizontal). It has a 61 oz. fuel tank with large openings for longer run time and easy refueling.

For user comfort, the MM4 mist blower has heavy-duty padded shoulder straps, anti-vibration mounts between the frame and engine to help reduce vibration on the user, and an L-shaped chemical tank to lower the center of gravity for improved balance. The PM7650H is equipped with mechanical automatic engine decompression for quicker and easier starts. By turning off the spray valve, the PM7650H can be used for blower applications.
