Abstract:
1. A method for controlling a fastener driving tool, said method comprising: (a) providing a fastener driving tool that includes: (i) a housing, (ii) a system controller having a processing circuit and a memory circuit, (iii) a fastener driving mechanism that moves a driver member toward an exit end of the mechanism, (iv) a prime mover that moves a lifter member which moves said driver member away from said exit end of the mechanism, wherein said lifter member acts both as a holding member and a release mechanism for said driver member, (v) a safety latch control device that is automatically controlled by said system controller, said safety latch control device, when commanded, being configured to move a safety latch member which has a catching surface, (vi) a user-actuated trigger, and (vii) a fastener; (b) initiating a driving cycle by pressing said exit end against a workpiece and actuating said trigger, thereby: (c) said system controller automatically actuating said prime mover, thereby moving said lifter member and causing said driver member to move away from said exit end toward said ready position; and (d) said system controller then automatically de-activating said safety latch control device, which allows a mechanical biasing of said safety latch member to move the catching surface of the safety latch member to a position that interferes with movements of said driver member.
