They use cartridges. Some are also convertible so you can pack it by hand from a bulk drum........Cartridges is the only way to go for less mess. Its easy to bleed them, or even a manual gun. I always pack the head portion with grease, and then only screw the head on partially, release the plunger rod, and then fish tightening up the head to cansister. 9 out of 10 times its sufficient to get any air out. I rarely use the bleeders on the top.
I made a pressure operated oil gun out of a manually operated grease gun. I use it to pressure lube odds and ends with heavy oils. Often oil does better at lubing something as it does not allow accumulated dirt etc to keep building up and is easly washed out and flushed with more oil. I use oil on my top link adjuster, and the ball ends on the lift arms.....
