OK - what is the correct way to do this....

I'm sure many of you are familiar with the 3oz. mini-grease cartridges. One end is open when you take the cap off, the other end has a foil seal on it.

Do you slit the seal, puncture a hole in it, peel it off or just leave it?

What is the correct way to use and install this type of set up?

Thanks in advance for your advice!

I'll try this from memory. Pull the spring-loaded plunger out the bottom, until it clicks over and stays put. Unscrew the "head" from the cylinder, remove the old tube. Remove the cap, and slide the grease cartridge in, foil end up. Remove the foil, and screw the head back on. Once the head has been tightened, release the plunger from the bottom end.
Make any sense?

Bingo... you got'er HRG. I have one. Just pucture the foil instead of trying to peel it off.

A puncture is all it takes

Those things have driven me crazy trying to pump grease after a cartridge change. If you have the same problem, what I've found to correct the problem is to leave the grease tube hand tight in the pump. After changing a cartridge, I remove the tube and pump the air out first.

Bad idea. Hand grease pumps can generate 10,000-15,000 psi, easily forcing a piece of foil through and into your bearing.

I peel the foil off. Never thought it may pump it thru to the bearing.

At the risk of being booted from the Manly Man club, read the directions.

throw it away and get real grease gun!

If you have problem with a grease gun that is airlocked, do the same thing to the grease gun that you can do with a bottle of ketchup.
Use a hammer and hit the grease gun outlet side and hammer toward the plunger. By banging on the outlet side of the grease gun, the grease is forced toward the outlet - expelling the air in the cartridge.

That is the same thing to do to get the air out of a ketchep bottle.
Don't bang on the bottom of the bottle. That simply knocks the ketchup back toward the bottom. Rather bang on the neck of the bottle, which will knock the bottle up in the air and thus bring the ketchup toward the open downward pointed outlet.

Take care

I always find that the rubber plunger that is supposed to go into the cardboard tube gets stuck on the edge going in and stops there. then it is a mess getting to go into the tube.

I have 2 of these guns and have never had that problem

maybe you need a new grease gun...

Small ones are even tougher. Unscrew gun, pull rod out in locked position. Helps to do this on ground, put rod on concrete so it dosent slip off. Pull all the aluminum off, drop in, spin on topper, now before pushing rod in get air out gun first like 6 or so pumps. Push it in see if you can get grease out.
