About This Product

RYOBI introduces the 18V ONE+ Grease Gun (Tool Only). 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). Best of all, it's a part of the RYOBI ONE+ System of over 300 Cordless Products that all work on the same battery platform.

                  Can you leave the grease tube in the gun? I probably won't use very much of it at a time. The instructions indicate you need to remove the tube when storing the gun. In that case, can I put the cover back on the tube or something?

                  Hello, Cnick - When storing, please follow the below instructions:    Lock the switch trigger in the “off” position and remove the battery pack.  Remove the grease tube.  Discard the grease cartridge (if applicable) and remove any old grease from inside the tube.  Reinstall the grease tube.  Install a battery pack, point the grease coupler towards an approved grease container, and run the tool until all the grease is expelled.  Lock the switch trigger in the “off” position and remove the battery pack.  Store the unit, accessories, and grease in an area that does not reach freezing temperatures. Do not store near a furnace or other sources of heat that could dry out the pump, high-pressure hose, or other components. Keep out of the reach of children.

                    Where can I find parts for this? I recently bought one and only used it several times only on my second tube of grease. I go to pull back the grease plunger and the rod snaps in half so I need a new Rod. Where can I get that?

                      I bought a new excavator that has grease more grease fittings than Wendy has freckles. It was tough trying to use a manual grease gun on that many fittings. This battery powered unit is a touch heavy but it really pumps a lot of grease. I love it and would highly recommend it.
                      by
                      I love the 18volt One+ feature. I’m a huge RYOBI user because I always have a charged battery ready to go with my other RYOBI tools. The grease gun works perfect with no assembly required and does a great job getting into tight places and doesn’t require two hands to pump the leaver, just a pull on the trigger. Good tool to have for sure. William

                          [This review was collected as part of a promotion.] We just bought this and are very impressed with it! Changed wheel bearing grease with ease and other grease fittings as well! Cons: the tip or came with wa faulty and the first zero we put it on we could not get off no matter how much we loosed it and it broke the zerk off, now we have to install a new one...

                                [This review was collected as part of a promotion.] I got this grease gun as a Christmas gift. I have 4 pieces of equipment and dread greasing them then I got this. So portable and powerful, I use the new PBP004 battery and it lasts through 2 tubes of grease. This is my16th Ryobi tool, I've included a picture of my original "Blue" screw gun which I accidentally buried 6 years ago in a ditch and dug up the next day cleaned it up with air and have used it ever since. I've yet to be disappointed by these tools. Many more I'd like

                                  [This review was collected as part of a promotion.] This grease gun is amazing, it cuts the time it takes to grease my mini excavator and skid steer. I would recommend using a 4Ah battery on it especially if you have stuck zerks. Only con would be that it is quite heavy but that could also be a pro meaning it's well constructed. Depending on conditions, I go through 1 or 2 tubes of grease a week.

                                    Can't use right out of the box
                                    Bought and brought home yesterday. Put in a fresh battery and loaded with grease and put it in the truck. Get out on the road today and have to park up and wait for equipment to get going and decide to try out my new tool and the fitting on the end of the hose is screwed down so tight that I can't loosen it even with pliers and a wrench. This makes the tool completely unusable and worthless until I get off work and get to a store to purchase a new fitting for the end of the hose and replace the factory one. Someones idea of a sick joke I guess.
