Stall Release (Fig. I)
If the nailer is used in rigorous application where all available

stall. The driver blade did not complete the drive cycle and the
jam/stall indicator will flash. Rotate the stall release lever
on the tool and the mechanism will release. If the driver blade
does not automatically return to the home position, proceed
to Clearing a Jammed Nail. If the unit continues to stall please
review the mode selection, material and fastener length to be
sure that it is not too rigorous an application.
If continuous stalling occurs, review speed selection.
Depending upon the application, a different speed setting may
be necessary.
