PROBLEM TO BE SOLVED: To provide a power tool capable of notifying a user of a difference in operation at a low temperature.SOLUTION: When a cell temperature measured by a temperature measurement section is a prescribed temperature Ts or below or cell voltage measured by a voltage measurement section is a prescribed voltage Vs1 or below, a microcomputer and a control section perform rotation control of a motor which is different from normal rotation control when the cell temperature is higher than the prescribed temperature Ts and the cell voltage is higher than the prescribed voltage Vs1 so as to notify a user of the effect.SELECTED DRAWING: Figure 2 |
