The Makita 18V LXT® Cordless 4-1/2" Chain Saw (model XCU01Z, tool only) combines performance with the convenience of cordless in a compact size. It is an ideal cutting solution for limbing applications. 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 XCU01Z Chain Saw has a 4-1/2” guide bar and the Makita-built motor delivers 980 FPM for increased cutting speed. It has zero emissions and reduced maintenance, with no need to drain the fuel for storage. Simply pickup the XCU01Z, load an 18V LXT® Lithium-Ion battery (sold separately) and the saw is ready to use. Additional features include “tool-less” chain adjustments for convenient operation and maintenance, and an ergonomic top handle design at 16-5/8” long with less weight (only 5.4 lbs., with battery, sold separately).
