Publication number: 20240123523Abstract: A saw including a lockout mechanism having a lever and a plunge stop. The lever has a trigger abutment surface and is movable between a safety position in which the trigger abutment surface inhibits actuation of a trigger and a use position in which the trigger abutment surface permits actuation of the trigger. The plunge stop is coupled to the lever and is movable with the lever between a first position and a second position. The first position corresponds with the safety position of the lever. In the first position, the plunge stop inhibits a motor housing of the saw from being moved from a raised position toward a plunged position. The second position corresponds with the use position of the lever. In the second position, the plunge stop permits the motor housing to be moved from the raised position toward the plunged position.Type: ApplicationFiled: October 18, 2022Publication date: April 18, 2024Inventor: David E. Dutterer

The lever is coupled to and movable with the lockout actuator and the pin. The pin is movable between a first position and a second position. The first and second positions correspond with the safety position and use position, respectively. In the first position, the pin is configured to inhibit a motor housing from being moved from a raised position toward a plunged position. In the second position, the pin is configured to permit the motor housing to be moved from the raised position toward the plunged position.Type: ApplicationFiled: February 24, 2022Publication date: August 24, 2023Inventor: David E.
