Decent grease gun
I bought this grease gun about a year ago. It never pumped grease very fast, and it finally quit. I figured I wasn’t out anything, so I took it apart and found a very fine screen that wouldn’t let #2 grease through. The best thing I did was to cut that fine screen out and put the gasket back in. Now it pumps like crazy and made it a way better grease gun.

I purchased this product when I started working as a heavy equipment mechanic. It has made that work far easier than with my old manual grease gun. In addition, I used this tool as a crewman on an M1A1 tank, and it was the envy of the company. It made jobs such as setting track tension significantly easier than they normally are with the USGI grease guns, and this tool survived getting thrown around in tank sponson boxes, dropped 10ft+ off of turrets (not intentionally and kept going. I still use it almost daily as a heavy equipment tech, and the only thing that has failed is the grease tube end got bent slightly, so that the pressure handle won't hold open for you to replace the cartridge (see 'dropped it off of a tank turret')

Buy it! Should have bought one when they first come out. Bleeding the air can be a little tricky, but 1 you tube video and it's simple now.

Makes greasing vehicles a breeze
I own many different off-road vehicles including ATV's, SxS's, sleds and an Argo. I have had many attempts at grease guns over the decades from various manufacturers and varying types. The DeWALT DCGG571 seems to have solved my issues - portability, ease of use, capability, flexibility.

I simply got tired of the pneumatic grease guns and air hoses getting tangled when i want to grease a tractor chassis. I'm very satisfied with this gun. It works great, powerful, and very easy to use. It may feel heavy when you're using it for a long period of time, but you get use to it.

Does it use same 20 volt battery as the XR Drill?
Junkyard on Aug 25, 2018

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
