1. A saw comprising:
a shoe;
a motor housing pivotably coupled to the shoe and movable between a raised position in which a saw blade is located above the shoe and a plunged position in which at least a portion of the saw blade is located beneath the shoe;
a motor located within the motor housing configured to rotate the saw blade;
a trigger configured to activate the motor in response to being actuated; and
a lockout mechanism including
a lockout actuator movable between
a safety position in which the lockout actuator inhibits actuation of the trigger, and
a use position in which the lockout actuator permits actuation of the trigger,
a lever having a first end coupled to and movable with the lockout actuator, the first end being movable along an actuator axis, and an opposite, second end movable along a pin axis, the actuator axis and the pin axis being transverse to the saw blade, and
a pin coupled to the second end of the lever and movable with the lever between
a first position corresponding with the safety position of the lockout actuator and configured to inhibit the motor housing from being moved from the raised position toward the plunged position, and
a second position corresponding with the use position of the lockout actuator and configured to permit the motor housing to be moved from the raised position toward the plunged position.
