I have a Grizzly G6049 angled finish nailer that keeps skipping firing
occasionally and then lodging a nail halfway in and halfway out. At
first it happened on 2 inch nails only, but lately it is happening on
all lengths. I have to disconnect, unjam the gun and push the driver
back down. This happens every 3 to 8 shots with the 3 being 2 inch nails
and the 8 being 1.5 inchers.

I was thinking this may be a compressor problem towards the low end of
the psi range it is factory set at(70 psi) but it is happening up to 80
psi. I guess the compressor, a Grizzly 2.5 hp. G8889 might have a
really bad gauge, but it would have to be off by 10-15 lbs since the gun
operates at 70-125 per the specs.

Any opinions as to whether this is a gun problem or a compressor
problem? The compressor cannot be set higher than 70 at the low end.

Or maybe it's a combination of both not doing so well?

Any ideas appreciated.

Ron:

Unless the pressure gets REALLY low, the gun will still operate. Some
of the framers and utility nailers won't function 100%, but with trim
guns this usually isn't the case. BTW, you can usually a few extra
pounds by adjusting the pressure switch - pull the cover off and you
will probably find a paper label telling you how you change the screw
setting to change the point it switches off and on.

Back to the guns. Some guns have return springs inside that wear out
or break. While they stay in their correct position so the pieces will
not chew up the inside of the cylinder, they do not operate properly.

Before you check that out, make sure the inside of the gun head is
really clean. Clean with a small wire brush and something like mineral
oil. DO NOT use an oil base lubricant such 3 in 1, or any other type
of household oil or lubricant as it can contribute to the dissolution
of your cylinder/trigger seals. (This is why air nailers use specific
lubes and oils).

Many times my guns need a really good cleaning to get the residual glue
from the nails off the head mechanism and they are fine. If not, take
the gun apart and look for something internal.

I hope to get a compressor HVLP paint gun and nail gun(s) shortly -- so =

the lesson is really appreciated.

Thank you.

Well it sounds like a recoil problem. You may want to be sure that the gun
is not bouncing away from the wood when you shoot. Secondly I shoot my
Senco gun at about 110#'s. 70 # sounds quite low and can also cause this
problem. The specs of you gun operating at 70# should be for thinner woods,
softer woods, or shorter nails.

Thanks guys. I'll look into the gun cleaning. I might also rent a
finish nailer and see if it does it also. I have a feeling my psi on
the compressor lowers to fast and then waits too long to recover.

In that case, add air capacity. Install a few 5-gal freon tanks
or the $30 air tanks from the current Schucks auto parts store ads.
Discharge air until the compressor kicks on and tank refills, then
shoot nails. You can run at higher pressures for longer times with
more air storage, Ron.

I think it would be cheaper and easier to simply have the pressure regulator
recalibrated.

Disassemble the gun, looking for dirt and bent pieces of mechanism.
Now clean it thoroughly, replacing bent and worn parts.
Oil all pieces as you reassemble unless instructions say otherwise.
Put it back together and see if it still skipfires.
