I bought this damn cordless grease gun the other day.


In the shop I'm at we use Lucas red grease and the other guys have cheap Lincoln grease guns that break all the time but have no problem pumping this stuff out,so I bought an ingersoll rand thinki it would be better but I was wrong.with the red grease it will only pump like a quarter of the tube and just stop.no matter what I do.i primed it right and everything,what's wierd is the way it ***** the grease.if I put a new tube in it will pump again but will stop again and can't even grease half a fifth wheel let alone a whole truck.i was able to run a whole tube through it only once and when it was done the tub was sucking it on itself on the side.when it stops pumping and I check the tube there's a sucked part on the side and in the center where it sucked the grease.

its ******* me off,in the other shop I found out they use a green Lucas grease.so I thought what the hell I'll try it.and guess what it worked and I pumped three tubes though it.the only thin is I have to hold the prim button when I push the piston rod back in.but it still works. So what the hell it should work with any grease,the other guys guns do.im thinking about trying to warranty it but what if the new one is the same and this design just doesn't like the red grease,maybe it's to thin?

What it looks like when it stops pumping

Anyone have an idea? I don't want to warranty it,I can use the green grease but still should work with red.WTF?!

I don't know. I had several tubes of the Lucas lithium and urea based grease and both of my guns at home did the same with the lithium (red) but not the urea (green), never had it happen with any other grease before or since. Just chalked it up to Lucas having air pockets or something in it and never bought any more. Wish I could still find Starplex II around here.

BTW, you really shouldn't mix the 2 kinds of grease. I have seen some bearing failures at my last place of employment after we switched over to urea based grease from the EP lithium. Did some research and found out the two bases aren't compatible.
