the pin pushing your nails is loose and the guides are warned .
try to change the guides and you will see that this problem will will be gone .
one last thing , make sure the coils are in good shape as it may create some feeding problems and push 2 nails at once

the piston that drives the nail is commonly known as a single acting spring return meaning air pushes the piston and the drive pin down driving the nail in and a spring is supossed to push the piston and pin back up to load the next nail the springs are not usaly very strong so lubrication could be the problem as well try using some "air tool oil " available anyplace airtools are sold do not use wd-40 or engine oil while these may offer temporary help they will come back to haunt you if a good oil doesn,t sole your problem then its "spring time" although they have lots of safeties built in when working with a problomatic nail gun please be careful high presure air risk of injection fast moving projectile again risk of injection Good Luck

If the driver moves on it's own then it's o-ring is shot,replace it. Pop the feeder cap and clean all the roof crud that's built up underneath it.Now you can see the feeder spring,check to see if broke or old and replace.The feeder plunger is air assisted so hook the air up and depress it, it should depress hard and pop right back up. If not it needs to be cleaned and new o-rings. If this doesn't work then it's a new feeder plate you need. good luck.

Are you using full round head nails?
The hissing indicates your O-rings are worn out and need to be replaced. This is not covered by warrenty and is common for all nail guns. Lots of kits are available on Ebay or your local Hitachi service center should stock them.
Hope this helps,

Trigger may be dirty, as an electrical switch the contacts can be intermittent. Also check to see if the safety plunger is set to correct depth and moving freely. Dirt can build up here......

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.
