I just bought some brand tentative air nailers but the piece didnt come with a brochure. it came near some oil and theres for a while sticker on each gun (3 1/2" framing nailer, 2 1/2" finish nailer, 1 1/4" brad nailer) that say to oil it everyday. theyre campbell hausfeld brand . i cant find a spot to in fact put oil contained by either. where on earth do i put this oil, how much of it, and how regularly? and do they come pre oiled or should i abstain from using them before oil them?
I enjoy had like peas in a pod nail gun since 1977.....and I've put a few drops of grease in the gun where on earth it connects to air hose. One piece I found out years ago....DO NOT use WD-40 ...it causes the seal to dry out and break. I don't oil mine respectively and every day I use them....but after a few hundred nail I put a little more grease in it.


Put a couple of drops of oil into the upper air inlet fitting. Once you connect it to the air hose, the grease will coat the innards of the nailer. I would say that each day oiling is overkill. I own used my for years with solitary and occasional drop of oil.

No sense over doing it because you will grasp oil everywhere.
Answers:    We oil ours 1 x month - put a few drops within the inlet air nouns. AND has be mentioned DO NOT USE WD 40!!! That's good direction!
