my kids got me a m18 grease gun for christmas, this last year. i've used pump grease guns all my life and i am not stupid. i run 2-3 cases of grease a year on the farm equiptment, is there a secret to getting all the grease out of a tube. ive never had this issue before, on a manual pump, i could clear air pockets , with out thinking. i've run it on the fast setting and now i'm trying the slow setting. i've never had a issue with wasting the last 1-4 to a 1/5th of a tube before. what am i doing wrong. when i start maintanencing the combine this summer, i want to have this figured out, it takes like a whole tube maybe more , to do a once over. there is some areas, that have zero tolerences for neglect of maintanence.. i need to know i'm using the entire tube.
