To free the lock button, squeeze the trigger and release.

NOTE: The lock button can be engaged only when the drill is running at maximum speed.

Never use the lock button when you may have to stop the drill suddenly.

3.This model is provided with a reversing switch (B) Fig. 2, and will operate in either the forward direction (clockwise rotation) for drilling holes, or the reverse direction (counter-clockwise rotation). For counter-clockwise rotation, stop the motor by releasing the trigger switch, and move the reversing switch toward the right side of the drill (or in the opposite direction for clockwise rotation).

NOTE: Never attempt to change the direction of rotation while the switch is “ON”. To do so may damage the interlock feature built into the switch. Be certain that the switch is “OFF” and that the motor has completely stopped before changing direction of rotation.

Be sure that the switch is “OFF” before connecting the drill to the power circuit.

4.Connect the drill to the power circuit. Make sure that the power circuit voltage is the same as that shown on the specification plate of the drill.

DRILLING OR HAMMER-DRILLING

Select the mode of operation by rotating the mode selecting knob (A) Fig. 3 in either direction (clockwise or counterclockwise). With the “D” toward the indicating mark (B) Fig. 3 on the gear case, the drill is in the drilling mode. With the “H” toward the indicating mark, the drill is in the hammering mode. You can change the mode of operation while the drill is running.
