The 18V X2 LXT® Chain Saw (model XCU02PT) is powered by two 18V LXT® batteries (36V), so you get 36V performance and run time for corded and gas-powered demands, without leaving the 18V LXT® platform. Model XCU02PT is a kit and includes two fast-charging 18V LXT 5.0Ah batteries and an 18V Dual Port Charger that will charge two batteries simultaneously for increased productivity and less downtime. It’s part of Makita’s expanding 18V Lithium-Ion system, the world’s largest cordless tool system powered by 18V Lithium-Ion slide-style batteries. 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. The XCU02PT Chain Saw has a 12” guide bar and the Makita-built motor delivers 1,650 FPM for increased cutting speed, but with less noise (only 89dB(A)). It has zero emissions and reduced maintenance: there's no engine oil to change, no spark plug to replace, and no air filter or muffler to clean. And there's no need to drain the fuel for storage. Simply pick up your XCU02PT, load two 18V LXT® Lithium-Ion batteries, and the saw is ready to use. Additional features include a "tool-less" chain adjustments, a front hand guard engineered to actuate chain brake when engaged, an electric brake for maximum productivity, and more.
