Fan running when trigger pressed is normal however to make it fire you need to press on the work probe first and the fan should start running, at this point the gas should be injected and pressing the trigger should create the spark to fire the gun, if all works as above but the gun won't fire check the gas, the metering valve on the can should have a yellow ring and when pressing the can nozzle on a hard surface, gas should be released, if not the can either has (a) insufficient gas, (b) the nozzle is not correctly fitted (c) the metering valve is faulty, if the can emits gas the gun will need to be checked for spark and the seals will need checking
First thing is to check date on the bottom of fuel cell. Make sure fuel cell is before that date. Now when you depress the safety and the fan comes on listen very closly at the top of the tool. If you hear a snap. Problem is solved. The plug wire is shorting to the head and is not getting into the chamber to fire the tool. Some times if you turn the lights out you can see were it is shorting. Many times it is were the wire goes on to the plug. If this is the case a little dilectric grease will take care of the problem.I remove the plug wire (you will need to remove the four cap screws on top) put the grease around the spark plug and reinstall my wire. reassemble and test. Good luck
This is a bottom fire tool. (NV83A2) You need to hold the trigger down and then as you place the nailer to the wood the safety will depress and it will fire once. This is usually done in one, swift action. If you do this in the opposite way by placing the tool to the wood and then pulling the trigger they often will double fire.
Not much information to go on. first thing to check is the date on the fuel cell. On the bottom of the fuel cell you will find a use before this date. fuel goes bad. next is tomake sure the battery is fully charged (light on tool should be green when you put battery in). With fastners in tool depress on wood. Now you should hear the fan start. Pull trigger and it should fire. If t doesn't, make sure there is not a jambed nail. Open quick release on front of tool. Remove jambed nail push driver back inside tool with small screw driver. Try to fire tool again, you may have to lift the tool again off the wood and press back down. when doing this you are putting fuel in the chamber and you might have to do it more than once. Hope this helps. please give more information if it des not. Good luck
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
You may have a broken tip or bent driver. Remove tha nails from gun and dry fire into a piece of wood. You should see a nice little indention. If you continue to hold the trigger and the nailer against wood after firing, the driver will stay in the lower position for examination. Just fire into wood and keep gun against wood while holding trigger and lean gun to side untill you see the tip. If you see broken tip or no tip order repair kit that includes driver, or driver alone from www.bostitch.com or ebay. Good luck
its all about the pressure you apply...to solve this try pushing down then firing....i know its a pain and slows work a bit but it'll save you staples and from possibly firing THROUGH the shingle...pulling them up is enough of a pain anyway... also see if you can tighten the tip of the gun...that should make it less responsive, tighten the trigger as well...good luck
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.
