3. Check the rotational direction

Triger switch

R marks L marks

R L

Selector

Button

Fig. 6

The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the selector button.

The L-side of the selector button is pushed to turn the bit counterclockwise. (See Fig. 6). (The L and R marks are provided on the body.)

◯When the trigger switch is depressed, the tool rotates. When the trigger is released, the tool stops.

◯The rotational speed of the drill can be controlled by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more.

◯When releasing the trigger of the switch, the brake will be applied for immediate stopping.

4. Change rotation speed

High speed Low speed

Shift knob	Shift knob
Fig. 7	Fig. 8

Operate the shift knob to change the rotational speed. Move the shift knob in the direction of the arrow (see Figs. 7 and 8).

When the shift knob is set to “LOW”, the drill rotates at a low speed. When set to “HIGH”, the drill rotates at a high speed.

CAUTION:

●When changing the rotational speed with the shift knob, confirm that the switch is off. Changing the speed while the motor is rotating will damage the gears.

●When a large force is required for operation (operations indicated in the following chart) set the shift knob to “LOW”. If “HIGH” is set and the unit is used, it may cause the motor to burn out or malfunction prematurely.
