Milwaukee2646-20 M18 2-Spd Grease Gun Bare Tool

I like the features, selectable pumps speed, and best of all no leaks or waste of grease. I have 3 vehicles to do the grease PM's on this tool makes simple work of the jobs. I was considering the yellow black tool however it leaks and does not last as long this coming from a shop that greases 10 to 14 rental machines a day that use 1 yellow and black and 4 red grease tools. No issues with the red tool.Quality and long term use with no issues was my decision for the comparative price.

The best battery powered grease gun I have used. I would buy again.

This grease gun works great! It makes greasing your equipment so much faster... just pull the trigger and grease. No more pumping handles, etc., especially in hard to reach areas!

Am in love with this grease gun . I tried other grease gun in the pass and they're nothing like this . I use it on my dump truck and it awesome .work fast and easy to use

Works well, I like the ability to control the speed and number of pumps if you choose to do so. I added a LockNlube pressure return valve on mine to make it easier to release off the fitting when they get too much pressure.

What can I say Milwaukee has done it again! I run a small mechanic shop and this thing works great. When it needs a new tube of grease theirs no hassle of bleeding the pump and making a mess. Worth the money

My husband loves it. He uses them at work and thinks they are quite the handy thing. He has several pieces of equipmentand it can end up taking a fair bit of time and effort to keep things maintained. It is very pricey, in my opinion, considering manual grease guns can be a tenth of the price. So, if you have lots of equipment that needs greased or some physical issue that makes manual applications difficult then it is definitely worth the price. Apparently, it's a great tool. Up to you if you think the benefit is worth the price.

For now, my rating of this gun is 4.5. Unfortunately, I only get to display 4 or 5 so 4 it is. I haven't got to use the gun yet, but I expect it to work just fine on my hobby farm small equipment. Should I have reason to alter that opinion, I will update this review.With that said, I want to focus on the #1 complaint about this gun. How hard it is to prime it. Others have already suggested relacing the OEM barrel with the barrel off a different gun. This may well work as I have no reason to doubt others words. However, I think there is a simpler more cost effective solution.Just like many others, I couldn't get the gun to prime on the first cartridge load, but I was aware of this issue from reading reviews and didn't panic. Although I couldn't find a video or write up specifically talking about how to do what I'm going to explain, I figured out what to try based on context clues from a few videos. Here is what I found.For some reason, possibly because the plunger is stuck or because there is a blockage in the path of the grease that the spring isn't strong enough to overcome, the plunger us not moving down. No amount of trigger pulling will make the gun work if the plunger isn't feeding down the tube. No amount of pushing the air release valve will work. So what I did was pull the rod back out without locking it in place. This was the first clue, the rod should not stay fully retracted all by itself. So I turned the rod until it seemed to lock into the plunger. There is no positive stop, you can turn the rod 3000 degrees. But if you stop at short intervals in the rotation, the rod seems to lock on the plunger. While holding the air relief valve, I pressed on the rod against the plunger and with a bit of force (not a ton), I heard a pop and the plunger pushed down the tube and grease shot out of the air reliefe hole. I turned the rod till it disconnected from the plunger, pushed it all the way back in, pulled the trigger and hey presto, the gun started feeding grease. You're welcome.I expect the reason a new barrel resolves the problem is because the plunger is getting stuck for some reason and the spring isn't strong enough to un stick it. Other barrels probably dont have a sticking issue. There may be some small defect in the barrels that come on the gun. But that issue may clear up once it gets broke in. Even if it doesn't, now you know how to deal with it.
