Grease Gun Help

I got a grease gun that uses air by accident. Am I still able to manually pump the grease out? I don’t have a air compressor. I think should be able to but I’m not sure. I don’t want to try it out just in case I need a manual one because I don’t have a air compressor.

Just return it and get the right one . Problem solved , your welcome.

No.

That’s why it’s called a pneumatic grease gun.

Yup I have one and you need air pressure so just return it. The standard ones are cheaper anyway, but why not get a compressor?
