Paslode finish nailer fan motor runs all the time will not shut off gun will not fire

SOURCE: impulse gun wont fire and fan doesnt run

could be a bent probe not allowing full travel of the safety , fan motor, loose wire, or circuit assembly. If you are handy with tools, remove the battery and fuel cell. remove the 4 screws holding the cover on top of the cylinder assembly and down where the saety is remove the 2 screws there also. gently pull the cylinder off the tool. when you have apart check toe condition of the Oring on the top plate where the fan motor is. Now reinsert the battery and you will see a rocker switch towards the top, depress it and the fan motor should come on. if not try and depress the trigger switch and again the fan motor should come on. If neither start looking for loose or broken wires, if you find none then I would guess the terminal board would be bad. you can also remove the handle halves and look for a loose connection at the board itself, they sometimes wiggled loose where it plugs in. Good luck and let me know.

Here's what I found at the Paslode Troubleshooting Site:
Tool will not cycle - fan runs, indicator light
is solid green.

Lockout bracket is stuck in lockout position.
Work-contacting element is bent, or build-up of
debris in track restricts operation.
Follower is not behind fasteners.
Fuel Cell empty.
Spark wire out of spark plug.
Spark plug is dirty.
No spark is generated.
Check lockout.

Remove and inspect lower probe. Clean and
lubricate track with Paslode Impulse® oil.
Repair or replace lower probe as required.
Position follower behind fasteners.
Replace fuel cell.
Remove cap and check spark lead, insert in
spark plug and replace cover.
Clean tool cylinder head and spark plug.

If this doesn't work, I suggest contacting Paslode directly 800-222-6990

there is no pendulum inside these guns it should work no matter what angle or upside down you are shooting it. If it is not retracting the piston trying cleaning the area and then lubricating really well that should do it if not repost and tell what that does.

Hope it helps you

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.

Sounds like it needs a drop or two of light machine oil in the air fitting
