PRIOR TO OPERATION
1.Power source
Ensure that the power source to be utilized conforms to the power requirements specified 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 sufficient 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 provided in the green tube (Fig. 1).
(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.
