The 18V X2 (36V) LXT® Brushless Cordless Couple Shaft Power Head Kit with String Trimmer and Pole Saw attachments is a welcome solution for a range of trimming and cutting applications. With zero emissions, lower noise and maximum versatility, the power head delivers maximum performance and run time without the hassles of gas and without leaving the 18V LXT battery platform. The lever style lock system allows for quick tool-less installation and replacement of attachments. The 10" Pole Saw Attachment provides 7-foot fixed length for trimming hard to reach branches and the String Trimmer Attachment includes a rapid loading bump and feed trimmer head loaded with 0.080" twisted quiet line. The couple shaft can also be used with multiple other attachments for edging, cultivating, and brush cutting (sold separately). The Makita-built BL™ Brushless Motor delivers up to 7,000 RPM with String Trimmer Attachment and 3,940 FPM with 10" Pole Saw Attachment. Makita’s efficient BL™ Brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per battery charge than similar non-brushless tools. Other features include a variable speed trigger to control cutting speed and Extreme Protection Technology (XPT™). XPT is a protective seal inside the tool, engineered for improved operation in harsh conditions by channeling water and dust from key internal components. It’s part of Makita’s expanding 18V LXT System, the world’s largest cordless tool system powered by 18V lithium-ion slide-style batteries. Makita® 18V LXT Lithium-Ion Batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. For improved tool performance and extended battery life, Makita created Star Protection Computer Controls™. Star Protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT Lithium-Ion Batteries with the star symbol on the battery indicating Star Protection inside.
