Abstract: A powered fastener driver includes a first cylinder, a first piston positioned within the first cylinder, a second cylinder in fluid communication with the first cylinder, and a second piston positioned within the second cylinder. The first piston is moveable between a top-dead-center position and at or near a bottom-dead-center position and the second piston is moveable between a top-dead-center position and a bottom-dead-center position to initiate a fastener driving cycle. A drive blade is coupled to the second piston for movement therewith and a drive mechanism is configured to drive the first piston between the top-dead-center position and at or near the bottom-dead-center position. The drive mechanism includes a crank arm that rotates less than 360 degrees for moving the first piston from at or near the bottom-dead-center position and the top-dead-center position and then back to at or near the bottom-dead-center position to complete the fastener driving cycle.

Abstract: A rotary tool including a tool body defining an axis extending between a rear end and an opposite working end, a motor configured to receive power from a power source, a drive shaft coupled to the motor with the motor, a chuck coupled to the drive shaft, and an axial adjustment mechanism. The axial adjustment mechanism includes an adjustment shaft having an axial end defining a floor of the chuck, where the floor limits an insertion depth within the chuck, and where the adjustment shaft is movable in a direction parallel to the axis between a first position defining a first insertion depth and a second position defining a second insertion depth.

Abstract: A heater including a housing, a heater unit, a control interface, and a fan unit. The housing includes a base. The heater unit is supported on the base and includes an ignitor mechanism and a heater element having an external surface configured to emit heat. The control interface is supported on an exterior of the housing and includes an actuator operable by a user. The fan unit is coupled to the base or the heater unit and is positioned to induce an airflow through the heater unit within the heater element to heat the airflow. The fan unit includes a fan shroud having an air outlet to direct the heated airflow radially outward.

Abstract: A power tool battery pack receptacle includes a cavity in which a portion of a battery pack is receivable, an insertion end, a closed end opposite the insertion end along an insertion axis of the battery pack, and a rail extending between the insertion end and the closed end. The rail includes a first portion having a variable height and a second portion having a substantially constant height. The first portion is positioned adjacent the insertion end and the second portion is spaced from the insertion end. The rail is configured to be received within a groove of the battery pack.

Abstract: A method for controlling a motor of a power tool including performing a load test on a battery pack of the power tool, determining, via a first controller, a first mechanism control scheme based on the load test, receiving, via the first controller, a user input indicative of beginning an operation cycle of the power tool, and isolating the first controller from a second controller. The method further including controlling, via the first controller, the motor based on the first mechanism control scheme, sensing a dataset indicative of a result of the operation cycle based on the first mechanism control scheme, receiving, via the second controller, the dataset, connecting the first controller to the second controller upon completion of the operation cycle, transmitting, via the second controller, the dataset to the first controller, and determining, via the first controller, a second mechanism control scheme based on the dataset.
