Abstract: A motor control module designed to control operation of a plurality of different motors in a plurality of different tools a power tool uses an electronic clutch in the module in conjunction with a mechanical clutch in the tool to protect the tool against an overload event. The module is adapted to implement methods to provide aural and/or tactile feedback to a tool user as a warning of an impending or current fault condition in the tool. The module can prevent power from inadvertently turning on either after an overload event has cleared with the tool plugged in and its power switch on, or after plugging in the tool within the power switch on. The control module is adapted to provide torque control for the power tool, to estimate tool motor temperature and to inform a tool user when a servicing need in the tool is required.

Abstract: A filtration system for a gas powered concrete saw allows the user to inspect and/or determine how much dust is accumulated in the filter. In addition, manual filter cleaners are provided to allow the user to easily clean the filter without needing to open up the tool. In addition, the system is provided to deactivate the tool or notify the user if no filter is being utilized, or the filter is damaged. The system can also provide system lock out in the case of a missing or damaged filter. In addition, automatic methods are also provided to allow cleaning of the filter.
