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 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 faulty 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
conditions conforming to prescribed precautions.

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.
