part time

[675602]

I am working on a Porter Cable finish nailer, FN250A, I have gotten a kit for the upper end part # 903767. My question is on the skematic of the tool it shows a part number 125, check seal. How far on the cylinder does this check seal slide? Do you slide it past the slotted holes in the cylinder or is it supposed to cover the slots?

Hi there,
The check seal will slide up from the bottom of the cylinder and completely cover the holes in the sleeve. Be sure that the thicker part is pointing up, and that the seal is lightly oiled before you up slide the seal onto the cylinder. I hope this helps,
