Senco Finish Pro 35 issue - Contractor Talk - Professional Construction and Remodeling Forum

sore thumb · 11-23-2008, 07:04 PM

i have a finish pro 35 that i used primarilly as a interior door gun

broke it out to do some exterior cornice work and it refuses to counter sink 2'' nails in exterior MDF

i have a SFN 40 that has no issues,the driver looks fine on the FP 35 so i dont know why its having issues,setts fine on softer wood,and yes its adjusted as deep as it can go

any ideas? they want $40 + bucks for a new driver blade,thought maybe it is broken but made a clean break but i dont want to shell $40 bucks out on a roll of the dice

any ideas?

Increase the air pressure?

Sometimes its the most obvious things that get overlooked - so unless the guns defective, it sounds like it needs some PM

Had the same problems with it on interior hardwoods, i believe it's just not as good of a quality gun as the snf40. Never had a problem with my snf40.

Is the gun clean & lubricated? I always run some marvel mystery oil through them first & then some air tool oil. The marvel seems to do a good job cleaning out any old oil & water that forms like a coating on the piston. At the very least it doesn't hurt anything, I use a little marvel in all my fuel cans for small equipment & it really does seem to keep the engines clean inside.

Maybe the piston is gunged up. If it has been sitting for a while it may need a good strip and clean. Unless you have shot quite a few thousand nails I would not think the blade is trashed. Do you use a water seperator on your compressor? If not then cleaning the gun thoroughly is where I would start. I have the sfn 40 and it's a beast so I would assume the 35 should be pretty good.

120 is the "Maximum Working Pressure". I have found that at this pressure, nails, brads and assorted fastners are usually "overdriven".

There does appear to be some other factor inhibiting your gun.

As for the $40.00. PEANUTS! C.O.D.B. (Cost of doing Business). Charge it out in another project.

I use the FP 35 on a daily basis. I have shot 10's of thousands of nails through it with out any problems. I use it on interior and exterior with SS, Galv and bright.

I make sure to oil it regularly and it serves me very well. It's funny...I had the "better" SFN40 a few years ago and it broke which forced me to use the back up FP35. I have used it ever since.

I would tear it apart and clean the piston and chamber. Even with regular oiling crap does build up causing some bad juju

thanks fellas,i'll dig into it this weekend and see what it looks like inside

cost of doing business yes,tossing $40 bucks away frivolously on a part that appears to be fine isnt really a good practice in any situation....all of my jobs are sq ft jobs with sq ft prices already set

thanks again fellas
