Re: Air grease gun

Don, I can't image putting the tube in backwards, in the fact the
*only* way the plunger will slide in is from the "raw" end with the
pull-off cap. If you put in the pull tab towards the plunger it would
never "clear" that, because the metal "ring" is smaller than the "raw"
end. Also the metal ring end is what "seals" against the "top" end so
the grease doesn't uz out. In fact on my hand gun, that's the way you
prime it. Apon screwing the unit back together, you don't tighten it
all the way; there's a little air hole at the top; letting the air out,
while the plunger works it's way up the tupe. Then when there's grease
coming out the little hole, then you tighten up the tube, and that
metal end "squishes" against the inside top end and seals it. If you
reverse the tube that "raw" cardboard end would crush.

Oh another trick and observation, lots of times a new tube will have a
ding or two on the metal part and needed a good seal (at discribed
above) I "smooth" the rim with a blunt object, such as the *** end of
a screwdrive (handle). BTW the metal end's normally aluminum, so I
assume it's suppost to squish for that reason (for the seal).

I forgot to mention I accually have two manual guns, one's that 'old
famialir big lever on the side, and the other one's a hand grip, both
which work fine over the years.

Keep 'em coming.
