a battery pack selectively coupled to the housing;
a motor supported within the housing, the motor electrically coupled to the battery pack when the battery pack is coupled to the housing;
a switch supported within the housing, the switch moveable between a first position enabling activation of the motor by the battery pack and a second position disabling the motor;
a trigger movably coupled to the housing between an OFF position and an ON position, the switch moves from the second position to the first position in response to the trigger moving from the OFF position to the ON position; and
a trigger lock-off pivotably coupled to the housing between a lock position and an unlock position, the trigger lock-off engageable with the trigger to inhibit movement of the trigger from the OFF position to the ON position when the trigger lock-off is in the lock position, the trigger lock-off allowing movement of the trigger from the OFF position to the ON position when the trigger lock-off is in the unlock position;
wherein the trigger includes a protrusion pivotably coupled to the trigger for movement with the trigger between the OFF position and the ON position, and
