Not all nailers have the ability to bump-fire. It depends on the type of trigger and the firing valve that the trigger contacts. Remove gun from air supply and remove the nails (for safety). Take a close look at the trigger itself looking for a bump fire setting. It will have a rotary dial to select single or repeat fire. If no setting, look at how the safety foot contacts the trigger's inner trip lever (the trip lever inside the trigger is what actually contacts the firing valve pin). With trigger pressed in, push the safety foot in and notice if the safety contacts the inner trigger lever. On bump fire trigger, the safety foot mech. will push up on the inner lever each time that you press in safety (and you will see that the inner lever will depress the firing pin). On single fire trigger, with trigger pressed, when you push on safety foot, the mech. will not contact inner trigger lever because the lever is too short to allow safety to make contact with it. On single fire triggers, the inner lever can make contact with safety only when trigger is in the resting position. With trigger released, depress safety and notice that safety contacts inner trigger liver and will remain in contact untill you press the trigger at which time the inner lever will depress the firing pin then fall away from safety. If you are a tinker-er, you can make adjustment to inner lever so that it will make constant contact (the rotary dial on triggers that are made to give you a choice of bump or single actually make the inner lever longer or shorter ). If you make any adjustments, make various and numerous tests with-out nails to make sure that it will not fire accidently.

Nailer wont advance the nails then it shoots blank


Try ez test to check for proper operation. Remove nails and air supply, point nose of gun up then down again. The driver should not move from the top of cylinder position. If driver is moving up then down replace the driver oring. If driver oring seems ok then connect air supply and bump fire the nailer without nails against soft wood and door open so that you can see the driver and feeder moving. Bump fire the gun and make sure that the driver is moving all the way back up to top of cylinder and the feeder is moving rapidly back and forward. If movement seems ok then hold the nose down on soft wood and depress and hold the trigger. This will fire the gun but driver will stay at the bottom position and not return until you release the trigger or lift the gun. When holding the gun with the driver down position, no air should leak out the top or bottom of the gun. If air leaks out bottom, replace lower bumper, if air leaks out the top replace the upper bumper. Good luck

Keeps repeating itself


Most nailers have a two position setting on the trigger to allow for single fire or bump fire. If set on bump fire, the gun will work better when you bump fire the gun instead of placing the gun on the work then depress trigger. Bump fire works best when safety spring has good tension. Easy test. Make sure that the safety spring is in place (with air hose removed, contact foot should spring back quickly when pushed against work). With air connected, hold trigger and quickly bounce the gun against the work. If the gun does not fire when you bump, the trigger is most likely set to single fire. With trigger set to single fire, you must place the gun against the work, then depress trigger. If the gun shoots two nails while set to single fire, most likely worn trigger or worn out trigger valve. These parts are not expensive and are easy to replace. Good luck

My makita an451 roof nailer keeps shooting 2 nails I've tried 2 different brands of nails


Nailers that use strips of nails (one nail directly behind the other) will sometimes drive two nails at once and is caused by damage to the driver. The nails are so close together that the driver will hit the first and part of the second nail head. Coil nailers, as your an451, use nails seperated by welded wire making it very difficult the the driver to hit the second nail. Usually when a coil nailer shoots two nails, it is acutally the trigger valve that acutates twice (two very rapid fires). Two very rapid fires is caused by faulty trigger valve. I have seen a roofing coil nailer fire one nail and a second nail drops out of the gun. Caused by weak / malfunction of nail feeder or wire used to weld nails together is too thick.

How does the framing nailer work with a black button grey button


Dewalt has two triggers available for their framing nailer. The black trigger (390746-00) is a bump style trigger. While holding the trigger, you will be able to fire a nail by pressing nose against work. This trigger is preferred by most framers because it is much faster. Gray trigger will only allow one nail to be fired. Bumping will not work with the gray trigger. With trigger released, you must place the nose against work then pull trigger to fire. To fire next round, you must release trigger, pull gun off the work, again place nose against work then press trigger. Check dewalt web site for recall information. Some dewalt framers have been recalled for faulty trigger. Good luck with your projects.

Gun will not shoot nails completely;no matter what wood,thickness,etc.they drive all but 1/2"


May be due to broken tip. Easy to check. Remove nails and leave door open. With door open, lightly tap the nose of the gun against coiled rubber hose or soft wood. The driver should stay at top position. If driver falls to bottom of the cylinder, replace piston oring. Now press nose of the gun against old coiled up air hose or soft wood and squeeze and hold trigger. The gun will fire and the driver should stay in the down position untill you release the trigger (if not single fire trigger, if single fire trigger remove trigger and press the trigger pin with finger). While the driver is down, make sure that the tip extends past the nose about 1/4 inch (if air leaks past the nose in this position, replace lower bumper). If the driver does not extend past the nose, replace driver. Good luck

Bostitch RN46 will not fire nail, only releases air when trigger is held and firing tip is touched to surface of material. Any ideas on what is wrong?


Gun will not fire if air is leaking past orings in head /headvalve or safety /trigger is not pushing trigger pin all the way into trigger valve. Test: Remove trigger to expose trigger valve pin. Remove nails. Place nose of gun against thick rubber mat or coiled rubber hose to absorb blow of driver. Very quickly and deliberately press trigger pin all the way in. If gun fires, safety foo or trigger is not pushing trigger pin all the way in. Make adjustments or replace worn parts. If gun still does not fire, remove head and pull out headvalve. Apply lots of silicone paste lube on the orings and the surface of the head where orings make contact. Reinstall head and test as above. If the gun fires then orings were leaking. Replace orings and sand any scratches on body of cap with very fine sand paper. Parts are at www.toolpartsdirect.com Good luck

What are my trigger options


The best way to soot 1 nail at a time out of a pneumatic roof nailer is to bounce fire it. Hold down the trigger and lat the safety fire the nailer as you bounce it against the roof.
