Is P3120H1-epc seized?
Snap On P3120H1-epc
I have a portable snap-on compressor very similar to the one pictured above. model P3120H1-epc. about 10 years old but rarely used.
It has 2 caps on top between the cylinder heads. One soft rubber,the other a screw type. Which of these stores the lubricant, how much, and what type?
