So for the better part of a decade I've had a pneumatic grease gun around the garage. But no instructions ever came with it. When I decide to grease something I just hook it up to the compressor, pull the trigger, and hope for the best. o No: Sometimes I get the goo, sometimes I don't. Do you pull the big handle out first? Do you push it in partly? Hey, I really don't know. After the last time I used it (successfully - I guess) it kept leaking goo out through what seems like a couple of relief valves at the top of the cylinder, even though it wasn't connected to air anymore. What's up with this? It finally quit oozing after a few months. But I don't know why! :laugh: I can't find instructions on the internet. Can one of you guys explain this crazy thing? :TU:
Hmm... I've never seen a grease gun that hooked up to an air compressor. Maybe you have some heavy duty gun that is not as common. I have a grease gun like the attached picture. Works like a caulk gun. Load a cylinder of grease, hook up gun to Zerk fitting, pump handle until new grease comes out. I've always had some extra "drip" with those guns as you build up pressure and take the gun away from the fitting before you have relieved that pressure.
Pneumatic grease guns are very common, but seem to work only so so. Mine works fine in perfect conditions, but if at an odd angle or sticky grease fitting, no no! Mine is a cheap one, so that might make a difference. I pull the trigger and get one squirt. I really wanted one that keeps pumping after the trigger is pulled. Any recommendations? - Bill
Yep - just like that one (only not in baby-blue :laugh. Mine is pink (not that there is anything wrong with that). Do you pull the plunger out (the t-handle thing) and then squeeze the trigger? That small round silver thing at the top of the cartridge - what does that do and why does mine expel grease even after unplugged from the air?
The gun loads like a regular gun. Leave the t handle in and simply pull the trigger. You should get one squirt. - Bill
