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.
5. Confirming condition of the environment:
Confirm 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
or 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.
(3) Pull the tool to make sure it is locked completely.
(4) To remove the tool, fully pull the grip in the
direction of the arrow and pull out the tool.
