Stanley Bostitch HP118K 23 Gauge Headless Pin Nailer Kit Questions & Answers
SB 1842bn
When a firing pin won't return it's usually caused by damaged o-rings inside the gun. The most likely culprits are the o-rings around the outside of the cylinder or the rings on the drive piston. Another cause could be a cracked cylinder or bent driver. Remove the cap on top of the gun and check the condition of the o-rings, cylinder and driver. You'll have to order any parts that need to be replaced as Bostitch doesn't make a rebuild kit for this gun. Don't forget to lightly oil the o-rings with pnumatic gun oil when reassembling the gun. Most pin and finish nailers say they are oil-less but they still need a drop once in a while to keep the o-rings from being damaged.
Just purchased a bostitch air
First, check all the air connections to see if there is anything that prevents the air to flow (pieces of cadrboard, packking chips or seals that need to be broken)
Check also if there is any manual valve and also if the quick connects are not entirely plugged in.
