Neutral (Fig. 9)

The Model DH 30PC2 has a neutral mode used for positioning a tool such as a cold chisel. Adjust the change

lever to "Neutral" ( mark). Engagement between the bevel gear and the clutch is released and no rotation is

transmitted. Then turn the grip of the tool retainer to adjust the tool to the desired position.

8-5. Caution when Using "Rotation Only"(No Hammering) Function

The chuck adapter and the drill chuck (optional accessories) are required for drilling into wood or metal materials.

The change lever of the Model DH 30PC2 permits changeover among "Rotation only," "Rotation and hammering"

and "Hammering only" functions. Be sure to adjust the change lever to "Rotation only" for drilling into wood or

metal materials by means of the chuck adapter and the drill chuck (optional accessories). If the change lever is

adjusted to "Rotation and hammering" or "Hammering only" for such operation, the drill chuck will be damaged by

hammering. Please caution the customers about the above.
