Needs very little oil, just few drops of sewing machine oil or nail gun oil sold at lowes or home depot. Purchase smallest size bottle of Paslode or bostitch nail gun oil (most likely they will not have hitachi oil). Do not by air tool oil as this oil is for air powered impact etc. Good luck

Factory and aftermarket parts are available. Check model number NR83a. Order from www.toolpartsdirect.com. Good luck

I usually order the springs from WWW.toolpartsdirect.com. Not expensive but shipping fee is about 8.95 if you order one part or many. Also check with nail or fastener companies in your area. If you buy nails from them they will give you a spring. To install spring check this forum for very good explanation. Good luck

Hitachi nailers cycle the whole cylinder as the air valve when gun fires. The orings are most likely too tight around the cylinder. Easy to check. Remove the head and depress the cylinder with thumbs and cylinder should pop back up. If the cylinder is down pull it back up and reinstall head. The hack method to get the cylinder up is to rap the gun head against hard rubber pad (with head installed and air connected). If cylinder moves down then up, most likely head valve gaskets (under headvalve ) or headvalve itself or top of cylinder damaged. Good luck

Easy to check. Remove nails from gun and connect to air supply. Using hard rubber pad or soft wood depress and hold trigger and push nailer safety against pad and hold there. The gun will fire but the driver will stay down until you pull back on the gun and relieve pressure on the safety foot. With driver down examine the tip of the driver. It should look square and should extend about 1/4 inch or more past the nose. If tip is broken replace driver. If lots of air is leaking past the nose during test, also replace the lower bumper. Good luck

Hi Gene, OK, so there's a factory recall on this one as you understand it. Have you been in contact with Hitachi, or one of their service centres to check this is correct? If this is NOT the case, it could possibly be that the timber you're using could be too hard??? just for you're own piece of mind, have you tried to fire the same nail into some soft pinewood to see if the result is the same? You've got everything else under control - pressure, leaks etc. so, the timber density may be the issue?

With the cordless nailers the problem is almost always bad fuel. When the pressure is low you don't get enough fuel by depressing it once, it may take two or three before it will fire. Just because you just bought it doesn't mean it's good - check the expiration date stamped on the bottom of the cylinder. There are also other problems - worn O-rings, bad spark wire, bent contact element that won't let the cylinder move all the way up to make the head switch to name a few.

The allen screw/s that you mention are there to plug holes where automatic equipment would normally connect (such as automatic nailing machines) . This is only a plug and should not be driven in too far. I have also seen allen screws installed in the head to repair small crack/s.

What model tool is it? -Jeff

oil it all the time

really depends on the model of compressor but if it is an oil less compressor best thing is to junk it and buy a oil lubricated with a cast iron pump dont get one with aluminum if you want a compressor to last you for many years.

Let it drain out then add oil to the compressor.

if its gas need engine info because it could be a couple of issues
