A power tool of the present teachings comprises a prime mover that drives a tool, a main switch that causes the prime mover to operate when the main switch is turned on and causes the prime mover to stop operating when the main switch is turned off, an illuminator that lights a working area of the tool, and a lighting mode selector switch for switching the lighting mode of the illuminator between a plurality of lighting modes which include a first lighting mode and a second lighting mode. When the first lighting mode is selected, the illuminator will be turned on for a first predetermined period from the point at which the main switch is turned off. When the second lighting mode is selected, the illuminator will not be turned on during the first predetermined period from the point at which the main switch is turned off.

1. A power tool comprising: a prime mover that drives a tool;a main switch that causes the prime mover to operate when the main switch is activated and causes the prime mover to stop operating when the main switch is deactivated;at least one illuminator that lights a working area of the tool;a lighting mode selector switch that is configured to be operated by a user independently from the main switch to selectively switch a lighting mode of the illuminator among a plurality of lighting modes, the plurality of lighting modes including at least a first lighting mode, a second lighting mode, and a third lighting mode; anda controller that is configured to: allow the lighting mode selector switch to change the lighting mode when the lighting mode selector switch is operated while the main switch remains deactivated,forbid the lighting mode selector switch to change the lighting mode while the main switch is activated even when the lighting mode selector switch is operated, andcontrol the at least one illuminator in accordance with the lighting mode selected with the lighting mode selector switch, whereinwhen the first lighting mode is selected, the controller turns on and off the at least one illuminator in accordance with activation and deactivation, respectively, of the main switch,when the second lighting mode is selected, the controller keeps the at least one illuminator turned off regardless of the activation and deactivation of the main switch,when the third lighting mode is selected, the controller turns on the at least one illuminator at the time that the third lighting mode is selected, andthe controller comprises a microcomputer that is configured to begin a setting process to enable the lighting mode selector switch to change the lighting mode of the at least one illuminator when the main switch is activated. 2. The power tool as set forth in claim 1, wherein when the first lighting mode is selected, the at least one illuminator is turned on at the point when the main switch is activated and turned off at the end of a first predetermined period from when the main switch is deactivated. 3. The power tool as set forth in claim 2, wherein a duration of the first predetermined period is adjusted with the lighting mode selector switch. 4. The power tool as set forth in claim 3, wherein the duration of the first predetermined period is adjusted in accordance with an amount of time that the lighting mode selector switch is continuously operated. 5. The power tool as set forth in claim 2, wherein the duration of the first predetermined period is adjusted in accordance with an amount of time the lighting mode selector switch is continuously operated. 6. The power tool as set forth in claim 1, wherein, when the third lighting mode is selected, the at least one illuminator is turned off at the end of a second predetermined period from when the third lighting mode is selected. 7. The power tool as set forth in claim 1, wherein a luminance of the at least one illuminator is adjusted with the lighting mode selector switch. 8. The power tool as set forth in claim 7, wherein the luminance of the at least one illuminator is adjusted in accordance with an amount of time the lighting mode selector switch is continuously operated. 9. The power tool as set forth in claim 1, further comprising: a mode indicating device that indicates selection of the first lighting mode when the first lighting mode is selected with the lighting mode selector switch. 10. The power tool as set forth in claim 9, wherein the mode indicating device turns on the at least one illuminator when the first lighting mode is selected. 11. The power tool as set forth in claim 1, further comprising: a storage device that stores the lighting mode selected with the lighting mode selector switch. 12. The power tool as set forth in claim 11, further comprising: a speed selector switch configured to switch an operating speed of the prime mover between a plurality of predetermined operating speeds,wherein the storage device stores, for each operating speed that is selected with the speed selector switch, the lighting mode selected with the lighting mode selector switch. 13. A power tool comprising: a prime mover that drives a tool;a main switch that causes the prime mover to operate when the main switch is activated and causes the prime mover to stop operating when the main switch is deactivated;at least one illuminator that lights a working area of the tool;a lighting mode selector switch that is configured to be operated by a user independently from the main switch to selectively switch a lighting mode of the at least one illuminator among a plurality of predetermined lighting modes, the plurality of predetermined lighting modes including at least a first lighting mode, a second lighting mode, and a third lighting mode; anda controller that is configured to control the at least one illuminator in accordance with the lighting mode selected with the lighting mode selector switch, whereinwhen the first lighting mode is selected, the controller turns on and off the at least one illuminator in accordance with activation and deactivation, respectively, of the main switch,when the second lighting mode is selected, the controller keeps the at least one illuminator turned off regardless of the activation and deactivation of the main switch,when the third lighting mode is selected, the controller turns on the at least one illuminator when the third lighting mode is selected, andthe controller comprises a microcomputer configured to begin a setting process to enable the lighting mode selector switch to change the lighting mode of the at least one illuminator when the main switch is activated. 14. The power tool as set forth in claim 13, wherein the microcomputer is configured to automatically quit the setting process when there is no operation to the main switch during a predetermined wait period. 15. The power tool as set forth in claim 14, wherein the microcomputer comprises a memory configured to store the lighting mode that is selected such that the selected lighting mode is maintained. 16. The power tool as set forth in claim 13, wherein when the third lighting mode is selected, the at least one illuminator is turned off at the end of a second predetermined period from when the third lighting mode is selected. 17. A power tool comprising: a prime mover that drives a tool;a main switch that causes the prime mover to operate when the main switch is activated and causes the prime mover to stop operating when the main switch is deactivated;at least one illuminator that lights a working area of the tool; anda lighting mode selector switch that is configured to be operated by a user independently from the main switch to selectively switch a lighting mode of the illuminator among a plurality of predetermined lighting modes, the plurality of predetermined lighting modes including at least a first lighting mode, a second lighting mode, and a third lighting mode, whereinwhen the first lighting mode is selected, the at least one illuminator is turned on and off in accordance with activation and deactivation, respectively, of the main switch,when the second lighting mode is selected, the at least one illuminator is kept turned off regardless of the activation and deactivation of the main switch,when the third lighting mode is selected, the at least one illuminator is turned on at the time that the third lighting mode is selected, andthe lighting mode selector switch is configured to become able to change the lighting mode of the at least one illuminator after the main switch is activated. 18.
