The 18V LXT® Lithium-Ion Cordless Compact Recipro Saw (model XRJ01) is a versatile cutting solution that combines variable speed and 1/2” stroke length with an exclusive dual-position on/off switch that allows for either paddle or trigger switch operation. Contractors get faster, more efficient cutting along with the convenience of “tool-less” blade changes and a fast charge time. It’s part of Makita’s expanding 18V Lithium-Ion series, the world’s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. Makita 18V 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® and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.
