BEFORE USE

Check the work area to make sure that it is clear of debris and clutter.

Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

OPERATION

1.Confirm the clutch dial position (see Fig. 5)

The three modes of screwdriver, drill and hammer drill can be switched by the position of the clutch dial in this unit.

(1)When using this unit as a screwdriver, line up the one of the numbers “1, 4, 7 ... 22” on the cap, or the black dots, with the triangle mark on the outer body.

(2)When using this unit as a drill, align the clutch dial drill mark “” with the triangle mark on the outer body.

(3)When using this unit as a hammer drill, align the

clutch dial hammer mark “” with the triangle mark on the outer body.

CAUTION

●The clutch dial cannot be set between the numerals “1, 4, 7 ... 22” or the black dots.

●Do not use with the clutch dial numeral between “22” and the black line at the middle of the drill mark. Doing so may cause damage (See Fig. 6).

2.Tightening torque adjustment

(1)Tightening torque

Tightening torque should correspond in its intensity to the screw diameter. When too strong torque is used, the screw head may be broken or be injured. Be sure to adjust the cap position according to the screw diameter.

(2)Tightening torque indication

The tightening torque differs depending on the type of screw and the material being tightened. The unit indicates the tightening torque with the numbers “1, 4, 7 ... 22” on the cap, and the black dots. The tightening toque at position “1” is the weakest and the torque is strongest at the highest number.

(3)Adjusting the tightening torque

Rotate the clutch dial and line up the numbers “1, 4, 7 ... 22” on the clutch dial, or the black dots, with the triangle mark on the outer body. Adjust the clutch dial in the weak or the strong torque direction according to the torque you need.

CAUTION

●The motor rotation may be locked to cease while the unit is used as drill. While operating the hammer drill take care not to lock the motor.

●Too long hammering may cause the screw broken due to excessive tightening.

3.Rotation to Impact changeover (See Fig. 5)

The “Rotation (Rotation only)” and “Hammer (Hammer + Rotation)” can be switched by aligning

the drill mark “” or the hammer mark “” with the triangle mark on the outer body.

To make holes in the metal, wood or plastic, switch to “Rotation (Rotation only)”.

To make holes in bricks or concrete blocks, switch to “Hammer (Hammer + Rotation)”.

CAUTION

●If an operation which is normally performed at the “Rotation” setting is performed at “Hammer“ setting,the effect of making holes does not only increase but it may also damage the bit or other parts.

●If it is hard to turn the cap to hammer mark “” position, turn the chuck slightly in either direction

and then turn the cap to hammer mark “” position again.

4.Change rotation speed

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.
