Converting a Powerbuilt Mini Pistol grease gun to bulk fill?


I just purchased a Powerbuilt Mini Pistol Grease Gun (model 548755). I wanted to convert it to bulk fill. I tried to follow the Operating Instructions For Hand Operated Grease Guns that was included with the grease gun. Your diagram looks nothing like this grease gun. Can you provide better directions - or a better diagram -- for converting this grease gun to bulk fill?



Hello Peter,
Being careful to watch how the plunger is assembled inside the barrel and, keeping the plunger spring under pressure; remove the nut holding the rubber wiper, turn the rubber around and, re-assemble so you can develop suction for the bulk fill.

Thanks for asking,
