Question about Hitachi NR83A2 2" To 3 1/4" Full Head Framer with Depth of Drive
My gun will fire and sink nails easy, however it leaks air from the
saftey plunger.I have found that the air leaks back from the head assembly through the tubes.I have replaced all the o-rings and gaskets
in the trigger and in the head.Anybody have some advice on what I
might have overlooked?
Most all Hitachi nailers that use the plunger style of firing/safety mech will leak air past plunger (part #877-339) when firing, however should not leak when connected to air or resting. If air is leaking past plunger when connnected to air check following:
Remove head to reveal cylinder plate (part#877-318). Remove plate and check outer oring for nicks or broken. If nicked or broken, replace and problem solved. If in good condition, remove cylinder guide (part #877-310) and check two outer orings for nick /cut. Use caution when removing/installing cylinder guide. It is easy to pinch orings when installing causing air leak at plunger. If orings are in good shape then problem is warped body of gun not allowing outer orings to seal. To check for warped body, use the cylinder plate as a guage by lowering it into the area where the cylinder guide rests. Good Luck with your repair.
