7.Press (and hold) the trigger Switch (24) to turn the drill on.

This Switch varies the speed depending on how far in it is pressed.

8.Optionally, after pressing in the trigger Switch, you can press the Switch On Locking Button to keep the drill running without keeping your finger on the trigger Switch (24).

Use this function when drilling soft materials only. Press the trigger Switch again to turn it off.

9.When you are finished drilling, release the trigger Switch to turn the Hammer Drill off.

Caution: Do not drill or hammer hard, brittle materials such as steel or concrete with the Switch On Locking Button pressed in (ON). If the drill bit catches on the material, the high torque of the drill will cause the tool body to twist around without stopping. This violent action could cause injuries to your hands and arms. It could also damage the Hammer Drill.
