Abstract: The present invention relates to a motor timeout of a power tool. When a trigger of the tool is unintentionally actuated, power is provided to a motor of the tool to cause an output assembly of the tool to operate. This can be problematic when the tool is being stored. To address this situation, the tool initiates or starts a motor timer when the motor is running at any nonzero speed. If the trigger remains continuously actuated, with the motor running at any nonzero speed, and the motor timer reaches a threshold limit, the tool ceases or discontinues to allow power to be provided to the motor, thereby shutting off the motor. This reduces the power source from being unintentionally discharged, and the chance of the tool creating a situation where the output assembly can unintentionally cause damage to the storage mechanism or other surroundings.
