RYOBI introduces the 18-Volt ONE+ Lithium-Ion Cordless Grease Gun Kit with 1.3 Ah Battery and Charger. It has a maximum pressure of 10,000 PSI, and a max flow-rate up to 7.5 oz./minute. The on-board LED work-light helps illuminate the workspace, while the 30 in. flexible hose helps to reach it. The plunger rod has markings that allow one to see exactly how much grease is left in the tube and the air bleeder valve primes the pump and reduces air pockets. Fearing runtime? Not anymore - pump up to 6 grease cartridges per charge when using the included 1.3 Ah Compact Lithium-Ion Battery. Best of all, this kit is part of the RYOBI ONE+ World's Largest 18-Volt Tool System*. Backed by the RYOBI 3-Year Manufacturer's Warranty, the 18-Volt ONE+ Grease Gun Kit includes a 1.3 Ah Compact Lithium-Ion Battery, an 18-Volt Charger, and an operator's manual.
