SOURCE: Hitachi Framing Gun Not Firing - Bad Battery?

Does the fan run and the light blink ont he nailer? I have one that I just bought. I put in the wrong type of nails and got one stuck. I had to take the front apart to clear it and now the damm thing wont fire. The green light blinks and the gas cartridge is basically full, even the fan does run after I release the push lever, but no fire???

I wonder if yours is the same as mine did fire for a couple nails first just fine then got jammed...

I will try to charge the battery more.... MAybe like yours it needs a strong charge for the spark...

Check the spark plug for debris:
This manual: Item 11 left side of the page.

Also make sure the spark plug wire is connected. You have all the indications that you shuold be able to fire... just no fire. That only leaves the spark plug item 11 and the wiring to the spark plug as suspected problem areas. Try removing the spark plug and testing it by grounding it to the chassis and pulling the trigger in a firing configuration. You may have gotten something in the plug during repairs or damaged the spark plug. You said you fixed a bad wire... given you have no spark is the repaired wired chaffing where you taped it and exposed and are of the spark plug wire to chassis ground? (

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

Fan is constantly
I deal with more paslodes but think Its the same concept... Theres a button/switch on the trigger and back cap... the back cap one turns on the fan when the tool is depressed and the trigger one fires the spark to ignite the gas.
Seems like the one on the back cap at the rear of the cylinder is stuck on.... or theres a problem with the circuit board

Paslode nail gun 325 black not firing
Any time these guns become intermittent or stop firing but the fan still runs, the first the to check is the expiration date on the gas cartridges. The do expire and this will make the gun work inconsistently or not at all.

IM250 Paslode straight brad nailer, fan wont shut off
My paselode was doing the same thing, and I followed all of the cleaning instructions, but the problem continued.

If it was left alone for a minute, it would fire again, so I removed the cover over the trigger assy, and checked the spark plug wire connection. The trigger came out, and during reassembly, I noticed that the electrical switch was hanging, and slowly pushing back out.

I cleaned and lightly spray/oiled the switch pin, and voila.........works like a charm.

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
