PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power source requirements specified on the
product nameplate.
2. Power switch
Ensure that the switch is in the OFF position. If the
plug is connected to a receptacle while the switch is
in the ON position, the power tool will start operating
immediately and can cause serious injury.
3. Extension cord
When the work area is far away from the power source,
use an extension cord of sufficient 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.

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.
Turn the tool while gently pressing it in, and the groove
of the tool will catch, allowing the tool to enter more
deeply until it is inserted all the way.
