I talked to Lincoln today who makes my Pneumatic grease gun. They pointed me to this Video which should be informative to most folks in some way.
I also have the Lucas manual gun like the video above. The Lincoln Pneumatic has a slimmer coupler, but that makes it harder to get on and off because it seems tighter.
