I second what he says many times i flipped on the welder and the trigger was touching something when i didnt know and put it in the alternate setings menu and messed everything up.
I went a little big for my garage just to figure in the efficiency loss at low temps. Garage is 20 x 24 i went with a 24k btu innovair from ebay. I can get 70 in here no problem at -20 can cool down to 69 in no time at 95 degrees . I couldnt be more happy with this after 2 year
I bought two of these for the shop to replace the 60 inch ones I bought from mcmaster. One lasted a little over a year , the other is still going. Btx they sucked I got more air from the 60 inchers

I have both snap on and mayhew , i prefer the snap on by a long shot. I wont even use the other ones they flex like a diving board. Never know whats going to happen when what your prying lets loose.
The few times I actually oiled my hammer, which I would use 4+ hours a day. I would just do a quick shot of pb blaster down the barrel. Otherwise sticking would occur like you said.
I work on garbage trucks and recycling facilities my job is defiantly not going anywhere. Throw away society that we are in just makes my job more busy. Some days I love my job some days I hate but that will be anwhere. but in the end I have a great family and every possibly material possession...
