drive knob or adjuster (A) f ig. 19. Test fire fastener and check depth. If   
the nail is driven too deep, rotate the adjuster clockwise to make the safe 
bracket push downward. Whereas, rotate the adjuster counterclockwise to   
make the safe bracket push upward. Repeat this step to achieve desired
