RYOBI introduces the 18V ONE+ Grease Gun Kit with 2.0 Ah Battery and 18V Charger. It has a maximum pressure of 10,000 PSI, and a max flowrate 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 1 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 19 grease cartridges per charge when using a P108 4.0 Ah LITHIUM+ Battery (not included). The included battery and charger are compatible with all RYOBI 18V ONE+ Tools. Backed by the RYOBI 3-Year Manufacturer's Warranty, the 18V ONE+ Grease Gun, a 2.0 Ah Battery, an 18V Charger, and an operator's manual.
