Remove the nails and air hose. tap the gun lightly and does the driver fall down?? if so it needs new o rings and doesn't have enough seal to drive the nail. also look at the condition of the driver. FOLLOW CLOSELY, reconnect the gun and remove the nails pull back on the follower and using a piece of wood to activate the safety hold gun at an angle, weara safety glasses and depress and hold trigger to expose the driver, does it extend past the nose and LOOK DONT TOUCH to check the condition of the end. release the trigger. this should give you some ideas why. also recheck the nails for proper collation and head are they clipped or full round. Let me know and I will try and help further. READ closely before attempting the above ideas.

Bostich RN-46 seems to be over sinking the nails even went set to low depth


Adjust the air pressure on the regulator to about 90 lbs. or lower. maybe higher than 90 but that should help you set the depth.

Miss fires and wont sink nails depth set deep and pressure over 120 psi


If no air is leaking from gun, miss-fire is usually caused by worn or too tight piston oring or lack of lubrication. Easy test. Disconnect airline, remove nails, point nose of gun up then down. Driver should stay in uppermost position. If driver moves up then down within gun replace piston oring and retest. Set pressure to about 100psi. Good luck with repair.

I have a dewalt framing nailer that will operate with a max pressure of 120psi. I have been using it for 2 weeks with 100psi. Now the piston will not return after shooting the first nail, unless I adjust...


Your gun should work in the 90-120 psi range to get a consistant drive depth and with a few drops, 5-6 or a small squirt, of oil at the start of work and a few more in the afternoon if you are using it a lot. It is possible to use too much oil, if you over oil it and the bottom of the cylinder chamber gets full of oil or other gunk attracted to the oil it can get high enough to interfear with the return function. Also if you are using something other than pneumatic nail gun oil it is possible some o-rings were damaged. Either way you have to remove the head cap and check the internal o-rings for damage and clean out anything in the cylinder and head chamber.

How do i set the depth


I have a older Hitachi 3 1/2 full roundhead nailer and on my there is a button on the front below the head at the end of the nails that you push sideways and hold and slide the nail gun tip up or down. There should be grooves across the front of the tip.

I have a RN45B roof nail gun that wont sink the nails all the way. How do I adjust depth of nails?


The adjustment is inside the magazine there are 3 setting depending on the length of nail. Here is a PDF of the owners manual for that tool, the procedure to set the depth is on page 6. http://www.bostitch.com/catalog_images/web_pdf/103280.pdf
If after setting the depth you are still having issues you can adjust the pressure on your compressor. The operating pressure for that unit is 70 - 100 psi. Do not exceed 100 psi and remember to disconnect your hose before loading/unloading or making adjustments to your nailer.

Adjusting airpresure


There is nothing on a nailer to adjust the air pressure. You have to do it at the pressure regulator. It is feasable to mount a regulator at the gun but more likely it's on the compressor. Most nail guns are rated for 90 to 120 psi. Set your regulator to hold the hose pressure between 90 and 100 psi. Using higher pressure to set the nail will ruin your nailer. Use the depth adjustment on the gun to set how far the nail is driven.

Hitachi nailer does not sink nails completely, no matter what size nail.


You must have broken tip or out of adjustment. Easy to check. Remove nails, and push safety against scrap air hose or rubber to absorb blow and squeeze trigger. Piston will stay in the down position until your release safety (on some models you will need to pull back on feeder sligtly). While piston is down examine the end of the driver for nice squared off tip protruding about 1/4 inch beyond nose. If no tip or looks broken, replace driver. If tip looks complete, adjust for more depth. Good luck

GUN NOT SETTING NAILS


Hello jsc.... the depth that the nailer drives the nail is dependent upon two factors, the hardness of the material you are driving the nail into and the air pressure. Generally when you want the nail to go in more you adjust the air pressure to a higher setting, going 5 psi at a time until you are close to perfect and then fine tuning the air pressure.

Sometimes people find that the air compressor itself is inadequate for the job. in that case, the only choice is to move up to a higher psi compressor. Joe

I have a Senco Framepro 701xp. I'm using a 3


What air pressure are you using? Try uping that, past 90 to about 105-110 max. What size air hose are you using? 1/4" is to small, need at least 3/8".

Framing nailer not setting nails


If your compressor pressure is right (im sure it is) there is a plunger located above the point where the nails come out. A moderately size tool store (not home depot) should have a rebuild kit. For me.it was where I bought my nails
