￿Turning the switch off

Release your hold of switch lever. Then, the switch lever returns forward on the main body by the spring’s force, and the switch gets turned off.

2.Pressing force of drill

You can not get holes quickly even if pressing it by strong force more than necessary.

It not only damages the tip of drill bits and decreases the efficiency of operation, but also shortens the life of the drill.

3.When drilling completely through the material

When the drill bit bores completely through the material, careless handling often results in a broken drill bit or damage to the drill body itself due to the sudden movement of the drill. Always be alert and ready to release pushing force and hold the drill body securely with both hands when drilling through the material.

4.Adjusting the drilling speed

D10YB is equipped with electric control circuit which enables non-step speed control.

To adjust the speed, turn the dial shown in Fig. 6. When the dial is set to “1”, the drilling speed is minimum speed (500/min). When the dial is set to “5”, the drilling speed is maximum speed (2300/min). Adjust the

drilling speed according to the material.

NOTE:

When the dial is set to “1”, there can be cases where no rotation takes place due to a power situation,etc.Inthiscase,raisethedialslightly before use.
