The 18V LXT Lithium-Ion cordless 29 oz. Caulk and adhesive gun (XGC01ZC, tool only) is a versatile, powerful, and lightweight solution for any contractor dispensing large amounts of caulk and adhesives, including window installers, drywall contractors, fire stop installers, commercial glazers, boat builders, and more. Its part of Makita's expanding 18V Lithium-Ion series, the worlds 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. The XGC01ZC delivers 1,100 lbs. of dispensing force for even the highest viscosity adhesives and sealants. It features a 5-speed dial with 0 to 66 In. per minute (IPM), and a variable speed trigger that allows the user to optimize the flow rate according to the application. It has a compact design at 18-7/8 in. with less weight (only 5.9 lbs. with 18V LXT battery, sold separately). Convenience features include a 360 rotatable cartridge holder that fits 28 to 29 oz. Cartridges, as well as a built-in L.E.D. light that illuminates the work area for improved visibility. The XGC01ZC also features an overload indicator light that notifies the operator when the tool is nearly overloaded to minimize breakage of the sealant cartridge.
