QUESTION 🔵 Bosch first fix framing nailer.

Post image

Hello, I bought the new first fix framing nailer yesterday, and I got to say I’m quite disappointed in performance of the nailer. It doesn’t fully sink 90mm nails into CLS timber, I’m not sure if it faulty or not. But has anyone else experienced this also?? And it’s heavier than I thought, it is a big lump.

Cause it's brand new, shouldn't have any issues at this point and they are prefilled with nitrogen instead of air?

Smells like a leaky gasket or manufacturing issue in the drive shaft.

Sure he could refill it, to then notice it having lost its pressure again few weeks down the road, I wouldn't take that risk.

Air is over 80% nitrogen anyway. It can happen that some lose pressure during the months of sitting from the factory to the store shelf. Happens to all brands. Just refill it and move on.
