1. Power source
Ensure that the power source to be utilized conforms
to the power source requirements specifi ed on the
product nameplate.
2. Power switch
Ensure that the switch is in the OFF position. If the

use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short
as practicable.
WARNING
Damaged cord must be replaced
or repaired.
4. Check the receptacle
If the receptacle only loosely accepts the plug, the
receptacle must be repaired. Contact a licensed
electrician to make appropriate repairs.
If such a fautly receptacle is used, it may cause
overheating, resulting in a serious hazard.
5. Confi rming condition of the environment:
Confi rm that the work site is placed under appropriate

6. How to install tool
CAUTION
For tools such as a drill bit and a bull point, use
only Hitachi genuine parts.
(1) Clean, then smear the tool shank with the grease
provided in the green tube.
(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.
