Where to add Oil?
I recently went to pick up my Dad's old compressor and it is similar to these types of compressors, in the picture.
Prior to firing this thing up, I wanted to know where I would add oil to it?
It seems to have a motor with a small wheel and another unit with a big wheel spun by a belt.
Do both units require oil? and if so, where do I apply and what type of oil do I use?
