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 power 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. How to install Drill bit
CAUTION:
To prevent accidents, make sure to turn the switch off and disconnect to the plug from the receptacle.
NOTE
：
When using tools such as Tine chisel, drill bits, etc., make sure to use the genuine parts designated by
our company.
(1) To attach the drill bit (SDS-max shank), insert it into the hole until it contacts the innermost end of
the hole as illustrated in
Fig.1.
If you continue to turn the drill bit with slight pressure, you can feel a spot where there is a hitch.
