(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)To remove the tool, fully pull the grip in

the direction of the arrow and pull out the tool.

7.Regulating the number of rotations and hammering (Fig. 3)

This hammer drill is equipped with a built-in electronic control circuit that can adjust and regulate the number of rotations and times of hammering. This hammer drill can be used by adjusting the dial, depending upon the contents of operation, such as boring holes into fragile materials, chipping, centering, etc.

The scale ‘1’ of the dial is designed for a minimum speed with the number of 120 rotations per minute and 1,200 times of blow per minute. The scale ‘5’ is designed for a maximum speed with the number of 250 rotations per minute and 2,500 times of blow per minute.
