How to connect coil spring in the channel of a hitachi roundhead framing nailker

SOURCE: I took my Hitachi NR83A

You do not need any special tools to assemble the pusher into the rails, however there is a trick to getting the spring in the proper position. I use a small pair of vice grips and a paper clip to hold the spring in position. The pusher slides into the rails easily. The back part of the pusher slides into the rails first. On the back part of the pusher there is a groove that accepts the spring, spring spool and pin. The pin will be in a vertical position and the spring will have the end tab with hole towards you. As you push this assembly into the rails you will loose sight of the spring end tab. You must hold the spring end tab at the bolt hole while you push in the assembly. This is done by bending the paperclip straight with very small hook on one end. Hook paperclip on spring tab hole and hold paperclip with vicegrip to position spring tab hole at bolt hole and push assembly all the way into rails untill it locks at rear or rails. This procedure can be varried with goal of holding spring tab at bolt hole. While holding tab in position insert rails into nose of gun and bolt rails. Just leave paper clip hook end there or pull out it does not matter. You are done. Good luck

Hi,
It goes thru the same hole as the magazine bolt on the nose. Sounds like yours is broken.

Are you using full round head nails?

The hissing indicates your O-rings are worn out and need to be replaced. This is not covered by warrenty and is common for all nail guns. Lots of kits are available on Ebay or your local Hitachi service center should stock them.

Hope this helps,

Cheers

You have one or more worn o-rings in the head of the gun. They direct the air to the proper parts of the gun to first drive the nail then to return the driver to the top of the gun for the next nail. Depending on the manufacturer and your model number, some companies make kits to replace the o-rings (always replace all of them). For some companies you have to get a breakdown of the gun and order each o-ring seperately.

it could be you are using the wrong nails, the gun should describe the correct angle and size.
