PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specifi ed 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 suffi cient 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 or
machine oil (Fig. 1).
Grease or machine oil
(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, pull
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.
