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 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, depress 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) To remove the tool, fully depress the grip in the

direction of the arrow and pull out the tool.

5. Regulating the number of rotations and hammering
