Abstract: A system includes a power tool and an automatic safety system communicatively coupled to the power tool. The automatic safety system includes one or more sensors disposed about the power tool, where the one or more sensors are configured to gather data about a safety parameter related to an operation of the power tool.

Abstract: A method for controlling a motor (2) which drives a disk-shaped tool (4) of a power tool (1) and to which a motor voltage in the amount of a nominal value is applied in an “on” position of a motor switch (6), includes determination of an actual motor current (IM) applied to the motor (2) and comparing it to a first predetermined threshold (GW1), and automatically triggering of a control process for protecting the motor (2) when an overload condition which is defined in that the first predetermined threshold (GW1) is exceeded beyond a first predetermined limiting time period (grDt1), is met, the control process including reduction of the motor voltage applied to the motor (2) by a magnitude that can be perceived by the user as a choke value.

Abstract: A hand-held power tool includes a motor (13) for driving the cutting or grinding tool (11), a fan (15) for cooling the motor (13), a protective cover device (30) for at least partially covering the cutting or grinding tool (11), and a guide shoe (20) for placing the hand-held power tool on a to-be-treated workpiece and having a tool opening (26) for the cutting or grinding tool (11) and at least one air guide channel (21) having at least one inlet opening (22) for connecting the air guide channel (21) with the fan (15) and at least one blow-out opening (23) arranged sidewise of the tool opening (26).
