Air Ratchet 3/8 CP where to oil?
I just got a Chicago Pneumatic 3/8 impact air ratchet used off eBay. Its old and I would like to get it up to speed. I know you oil thru the bottom a few drops before and after use, running it slowly each time after oiling for a minute. However, I am thinking that I need to take the ratchet apart and grease the parts. The is also a slotted screw on the side that I think I remove and fill with SAE 30 weight oil about halfway? I can not see a model number anywhere and this wrench is solid metal with not black pain on it anywhere.
Can someone please advise me more?
