PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, which could cause
a serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Mounting the drill bit (Fig. 1)
CAUTION
To prevent accidents, make sure to turn the switch
off and disconnect the plug from the receptacle.

work. Do not use them for wood or metal drilling
work.
Dump particles after every two or three holes when
