    Can this be used to pump motor oil? I know it is not designed for it. For work we use a hand grease gun to add oil to valve actuators with a threaded connection. I am tired of hand pumping. Would this work for that same application or it has to be grease

    We do not recommend using the 20V MAX Cordless 10,000 PSI Variable Speed Grease Gun (Tool Only) in this way.

      Answer This Question

      No, you will need to use the purge valve to bleed off any air that may be trapped in the cartridge.

            The DCGG571B is compatible with the FLEXVOLT battery. The FLEXVOLT battery will act as a 20V battery in DEWALT 20V tools.

                    Out of the box all you need to do is load a tube of grease, put a battery on and go. I work for a rail company and it used to take 20-30 minutes a wheel to lube. Now it takes 5 minutes. Loading and unloading the tube is so much easier than my old grease gun. Fits into my toolbox easily and does not leak in the toolbox. Overall totally satisfied with this purchase

                    This product works very well. I used it for wheel bearings and had no issues. It was very easy to blend the air out of it and fit a grease tube well. Just make sure to have rubber plunger fight way for tube or drum grease which is in the instructions. Mine was set up for tube out of box.

                    This grease gun is the best out there, pumps very fast and is lightweight. Easy to use, very efficient and it’s easy to change the tubes out. The light at the bottom comes in very handy and i love the length of the hose. Has a relief screw just in case u have issues priming it. It saves me a lot of time over a manual grease gun because i grease semi trucks. Ordered it online and it came the next day.

                    Great Gun to Save your Hand from Cramps!
                    I have had numerous grease guns, from pistol grips to long handles but they all require one thing, pumping by hand! I wish I could go back in time and save myself the trouble of fighting with manual guns by buying this product a long time ago!

                      I am satisfied with this product. The variable speed trigger is a great feature. It allows me to control the flow of grease with ease. First, I lightly press the trigger to verify that the fitting is not clogged, then I press the trigger further to quicken the greasing time. The pressure relief valve is another thing to admire. This is the first time I have used a grease gun with this feature. I must admit, when i saw it purge I thought something went wrong. Then I read the manual and it became clear. The reason it purged was due to the fact that the fitting was clogged. This prevents the grease gun from over working the motor, which increases the longevity of the tool. I like that! The last thing I would like to share is that the bundle was an amazing deal. The bundle included a 4.0A 20V battery! The battery alone is worth $100. There’s was no way I was going to let this opportunity pass. Thank you

                      I always had access to a powered grease gun at my old job. The Company supplied one for us. After I retired away from that jobsite, I thought I could get along without one. WRONG! I have since acquired several DeWalt power tools, so when this deal popped up, along with a special on the batteries, it was a no-brainer! Along with this deal, I got called out of retirement which brought up the need for a power greasegun of my own. Wins across the board!!
