Stuart - this sounds like an air problem - you should perform the following test. With the air nailer close to the compressor you must monitor the airpressure after the gun fires. it sounds like the air is not gettting through diapram fast enough or there is a blockage in line. Blockage in line is not suspected for the following reason . It sounds like the air hose is holding enough air to fire 2-4 nails and then you must wait for the line to fill up again and then it fires ok. The pressure regulator out to the line controls this and they do fail. try this test and report back to me - I know I can solve this for you as I have extensive background in compressor and the like.

SOURCE: Bostitch nail gun loss of pressure, won't fire nail

Hello. I can help you. The nail gun you have uses 18 gauge brads. I would use only original Bostitch 18 gauge.

The one MM of difference you mention is the reason why you do not have the pressure you did have. Get rid of those 31MM brads and get the 18 gauge. Home Depot carries the Bostitch line. I would go there or to homedepot.com

SOURCE: gun does not fire every time

When you cleaned it, you may have pinched the large brown o-ring that is around the fan. Take gun apart again and reassemble. before you place the orange head valve cover on, press the nose of the gun into a wood surface and assure the o-ring goes into chamber unrestricted. Basically, the aluminum fingers of the cylinder should not pinch off the o-ring.

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

Makita gn900 gas nailer, trigger is sticking sometimes and I have to push prongs in to release, can anyone help..?


Wild guess. You've been using a long time. I'd try a little WD-40.
NO help? may need to replace trigger mechanism.

Makita gn900 nail gun wont fire on half full gas cell


Hi... mine had the same problem when I bought it cheap second-hand. I made a spacer out of a washer that slips over the gas stem adapter and so far 100% fire rate. It holds the adapter closer to the cartridge nozzle and opens the valve that releases the gas when the trigger is pulled. Too easy! Good luck.

Nail not firing, battery charged, fuel cell good,


When you took it apart to clean it, you may have piched off the large brown o-ring on the head valve. To check this, take the orange head valve cover off and push the gun downard onto a piece of wood as if firing it. Watch the o-ring to see if it clears all the metal fingers around the fan.

Jammed makita an923 nail gun


On most all nailguns when the trigger is activated air pressure is released from the headvalve causing the headvalve to open and fire the piston. If air leaks through the headvalve orings or through the headgasket port to headvalve, it will not fire. Try applying light grease to headvalve orings and make sure that headgasket is sealing around vent hole. If it fires then replace orings in headvalve for long term repair. Secondary problem is worn safety parts and trigger or trigger pin. If these parts are worn the trigger will not push the trigger valve pin all the way in when you bump fire the gun. With air supply disconnected, apply pressure to safety while depressing the trigger and check thet the pin is moving all the way into the trigger valve. Adjust or replace as necessary. Enjoy

Nail Guns Safety problem


Professional-grade varieties are automatic, and fire a nail directly upon pulling the trigger. A semi-automatic nail gun is more appropriate for beginners, since it requires a two step process: pull the trigger and then tap the barrel against the wood. This safety feature protects the user from accidentally firing a nail gun and injuring himself or others.
