paslode nailer

[geechj]

I have a new paslode finishing nailer that is currently not working. The fan kicks in and it appears to be activating the fuel, but no firing. I've followed the instructions and did a thorough cleaning of everything, but that didn't affect the 'no firing' problem. I removed the fuel cell and attempted to fire it to see if i was getting spark and i could hear a "phh", which i assume is the spark. Any experiences or thoughts??
thanks.
