Abstract: A cut-off saw includes a saw housing having a support arm that protrudes outward from the housing front end. A blade drive assembly disposed in the support arm includes a gear set and is configured to transmit rotational motion of a motor to the cutting blade. A lock handle is pivotably mounted on an outer surface of the support arm and is configured to actuate a locking pin. In a folded position, the lock handle is configured so that the locking pin is disengaged from a drive gear whereby the blade drive assembly free to drive the cutting blade. In the unfolded position, the lock handle is configured to cam the locking pin into engagement with the drive gear, preventing rotation of the cutting blade. The unfolded lock handle serves as a manual grip that permits a user to stabilize the saw while attaching and detaching a cutting blade.
