Question about Air Tools & Compressors
I truly think the flashing is the sole problem & that they knew that, but wanted to ensure I would have to buy a new roof. It is very high & steep. I can get someone up there (does it have to be a roofer?) to replace the flashing, but what can I do about those 200 nail holes?! Thank you sooooo much! :)

Max nailers are very good quality and parts are not expensive. Parts and parts list at www.toolpartsdirect.com. Check the following to repair not feeding problem.
Check paw in the door should have a light spring action. Feed paw should have a medium spring action. You may have to pull the feed piston back and hold to check feed paw spring action. Feed piston should have heavy spring action. If springs seem ok then remove feed piston and replace two orings. If the feed piston spring is broken replace with correct part. Make sure that the ports that direct air to feed piston are not blocked with bits of rubber or dirt. Sometimes parts of the bumper will break off and spread thru-out the gun. Good Luck and enjoy. (parts not expensive)

The F28WW takes 28Deg nails that are collated with wire, so your nails won't work in that gun. The N80SB is also a 28Deg nailer so your 30 Deg nails won't work in that gun either. Sorry about the bad news but it looks like your going to have to spring for new nails

You dont mention how many holes there are to be sealed, I would assume less than 10? .. a couple of options spring to mind but there may be more!
1. Try using Eternibond sealing tape over the holes .. apparently good for 25-35 years! .. will need to clean the surrounding area carefully before application. Link to site http://www.eternabond.com/
2. You could always use the roofing screws and associated rubber grommets to ensure a watertight seal of the old holes. You may need to place some wood on the underside for the screws to bite into. This may be the cheapest option.
Hope this helps - if so, please leave feedback, if not let me know and I'll try and help some more!

SOURCE: my makita an451 roof nailer
Nailers that use strips of nails (one nail directly behind the other) will sometimes drive two nails at once and is caused by damage to the driver. The nails are so close together that the driver will hit the first and part of the second nail head. Coil nailers, as your an451, use nails seperated by welded wire making it very difficult the the driver to hit the second nail. Usually when a coil nailer shoots two nails, it is acutally the trigger valve that acutates twice (two very rapid fires). Two very rapid fires is caused by faulty trigger valve. I have seen a roofing coil nailer fire one nail and a second nail drops out of the gun. Caused by weak / malfunction of nail feeder or wire used to weld nails together is too thick.

If a gun is firing and nails are not being driven into the work it's because of one of two problems. The nails aren't feeding fully under the driver or the driver isn't fully retracting each time the gun is activated. Is looks like you've eliminated a feed problem so you are going to have to take the gun apart to find out why air is not being held in the bottom of the head long enough to push the driver back up the cylinder. Go to www.ereplacementparts.com and bring up your model so you can follow along. Remove the four screws holding the head cap on. The things that can cause your problem are: the piston seal & o-rnig are damaged, the cylinder is badly scored, the o-ring & cylinder ring on the bottom half ot the cylinder are damaged or out of place, or the driver guide under the bumper is broke or missing. If it turns out internal parts are damaged or missing, I highly recommend the overhaul kit to replace all the 'soft' parts inside the gun as long as you have it apart.
