Grease gun help
I never thought of myself as being mechanically challenged, but...
I have a new garden-variety, lever-action grease gun. The coupling easily attaches to grease zerks, stays on, doesn't leak, I can grease whatever; it works great. Until... I try to detach the damned thing from the zerk. I can't pull it off, can't pry it off, and have even yanked out the zerks trying.
The only way I can disengage the coupling is to disassemble it.
What's the secret? Do I have a faulty coupling? I can't believe it's supposed to work this way.
