Flush Too deep
NOTES:
When adjusting the adjuster, it does not rotate more
than 3 mm from the deepest point where a nail goes
down. Do not rotate the adjuster by force beyond
that point.
The nail-driving depth can also be adjusted by
changing the air pressure used. Carry this out together
with movement of the adjuster. Using a high air
pressure that does not match the nail-driving
resistance will shorten the life of this nailer.
