Paslode 350 tell no light

If you have no light at all in the handle and you're sure you have a charged battery, then I would look at the battery contacts - that tool has the contacts molded into a circuit board assembly so if it is not obvious I would take it to a repair center to be diagnosed.

Changed the circuit board on a Paslode IM350 and now the fan wont work any Ideas welcome

fan motor could have gone bad, spark unit(little black box in handle) could be bad. one of the three top conections could be loose, or hooked up wrong, battery contacts on end of circuit board assembly could be placed a little off( battery not making contact with circuit mold assembly) pinched one of the wires going to the trigger area, or fan area

Paslode fan runs half spped and will not fire unless fan motor is unplugged

if your fan motor is ok, which it probably is, it has got to be the spark unit . the spark unit is the brains of the operation. the little black box located in the handle of the tool( the spark unit ) can cause fan to run slow or not at all. its a bit expensive( probably 60-80 dollars) but not that hard to change out. if its the original be careful pulling it out its glued in from the factory.

I have a paslode cordless framing nailer 900420, just changed the molded circuit board and worked fine, put it away for about 4 weeks when I went to use it again the fan will not come on and will not fire


Here is a tip that I wrote about the Paslode nailers and the problems that can come up with them.

I also have a link to the Paslode manuals which contain Paslode cleaning and troubleshooting guides.

If you need parts for your Paslode, there also is a link for a site that sells the Paslode nailer parts.

Paslode fires just as you realease the gun from the surface

sounds like the trigger m8 the only way to cure it is to replace the molded circuit assembly 900475. but try cleaning the trigger switch and make sure the spring is seated properly. hope this helps m8

Paslode 900420 piece fell out

Be sure to remove the metal nose piece that covers the lockout bar when assembled. It may be stuck to the other half of the gun. Replace the bar and the spring and put the metal nose piece in its position over the lockout bar. At this point the metal nose piece will be on the opposite side. This will allow you to replace the 2 halves carefully so as not to loose the spring.
