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. How to install tool
NOTE:
For tools such as a bull point and a cold chisel,
use only Hitachi genuine parts.
(1) Clean, then smear the tool shank with the grease
provided in the green tube (Fig. 1).
(2) To attach the tool (SDS max shank), insert it into
the hole until it contacts the innermost end of the
hole as illustrated in Fig. 2.
If you continue to turn the tool with slight pressure,
you can feel a spot where there is a hitch. At that
spot, depress the grip to the direction of an arrow
mark and insert the tool all the way until it hits
the innermost end.
Releasing the grip reverts the grip and secures the
tool in place.
(3) To remove the tool, fully depress the grip in the
direction of the arrow and pull out the tool.
5. Regulating the number of rotations and hammering
(Fig. 3)
This rotary hammer is equipped with a built-in
electronic control circuit that can adjust and regulate
