service center.
Stall Release (Fig. J)
If the nailer is used in harder material where all available 
energy in the motor is used to drive a fastener, the tool may 
stall. The driver will 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. 
NOTE: The tool will disable itself and not reset until the 
battery pack has been removed and reinserted. If the 
driver does not automatically return to the home position, 
proceed to Clearing a Jammed Pin. If the unit continues 
to stall please review the material and fastener length to 
be sure that it is not too rigorous an application. The nailer 
could also be overheated and needs time to cool before 
further use.
