The Makita 18V LXT® Lithium-Ion Cordless 4 Ft. Concrete Vibrator Kit (model XVR01) delivers more run time with maximum vibrations per minute (VPM) for strengthening concrete when running a corded tool is not an option. The XVR01 weighs only 7.7 lbs. with battery, with high vibration and ergonomic features for top performance. The Makita-built motor delivers 13,000 VPM and up to 25 minutes run time under load using a fully-charged 18V LXT® 3.0Ah battery. The 4 Ft. shaft is 1” thick for more effective leveling and removal of air bubbles in concrete. 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.
