Works like a champ. Did not work until figured out how to prime the unit. To all the ones that gave it one star Gun will not prime properly when restricted 1) remove hose\ tube with nozzle 2) install cartridge 3) connect air supply 4) operate trigger to eject grease 5) install preferred output connection Enjoy a great tool
Don't waste your money on this item it is a piece of junk! This thing stopped working after 3 shots of grease, you could hear the the pump locked up. I returned this and was given a replacement, and sure enough after the first shot the end of the hose blows off and then this one wouldnt stop shooting grease. Had to return and am now on the third one, wont even take this piece of **** out of the box.
It will not pump grease.
It does not want to pump grease.
It will never pump grease.
Add "H3LL" in front of each no.
I rated it one star because there are no minus stars.
Returned it. It was hard to load the grease cartridge, and when loaded, it wouldn't pump it out. I've been a mechanic for 40 years, and would not recommend.
