Safety Time Out & Self-Correction Capability Fusion is the smartest nailer ever developed! Time Out: Helps prevent accidental actuation of the tool when carried with the trigger in the “bump fire” mode. Self-Correction Mode: If the battery runs out of power, or if there is a jam resulting in a time-out, the tool automatically resets itself when actuated again (safety depressed/trigger pulled). After it resets, the tool is read to operate. Lithium Ion Battery - Up to 600 Shots Per Charge On charge, the 18v battery reaches 80% capacity in approximately 15 minutes (100% in 45 minutes).
