Hitachi 83a2 (s) framing nailer jamed, there are 2 nails in cylinder, not sure how to clear the chamber. .
1.Remove the air hose
2.Hold the nose down on a 2x4 on the ground. Make sure the safety guide is full depressed.
3.Squeeze the trigger.
(I realize that sounds redundant, but I have to insure your safety as much as possible. We at FixYa want you to be safe. A Framer Nailer can be dangerous if safety precautions aren't observed)
4.Pull the slide back, and grab around it with your hand, up against the back of the gun. (Magazine)
If you accidentally bump the latch lever, the slide won't spring forward, possibly causing you injury by using this method.
5.Remove any nails. Pull the plastic strip of nails out.
6.The method I use here is to rest the air chamber cover on a table. (Top of the gun) Nose AWAY from your face. I use a small flat tip screwdriver, and see if I can move the Driver back up into the gun. Then see if I can ease one nail out at a time, by moving the nail down out of the nose.
You have two nails trying to drive out at the same time. They need to be separated from each other, so that you can get one nail out at a time.
Most of the time this occurs because of lack of lube. The gun is supposed to have 4 to 5 drops of pneumatic oil, added to the air hose inlet before starting the day out.
(Gun is faced so that the air inlet connection is straight up, oil is added, while the trigger is being squeezed in at the same time)
I don't rely on oilers in the air line. I think they're a bunch of hooey. I've had very few problems, when I have added oil manually at the start of the day.
Sometimes using those 'bargain' nails will cause a problem also. If you find a brand of nails that are cheap, this is the usual result.
Sometimes we framers are too fast on the trigger, and do not have the safety guide fully depressed, before firing the next 'shot'.
If you have further questions please post them.
