1. Disconnect the charger power cord from the AC outlet.
2. Hold the charger tight and pull out the battery.

PRIOR TO OPERATION

1. Setting up and checking the work environment

Check if the work environment is suitable by following the precautions.

HOW TO USE

1. Confirm the cap position

The three modes of screwdriver, drill and impact drill can be switched by the position of the cap in this tool.

(1) When the tool is used as a screwdriver, align the number displayed on the cap from "1" to "5" to the triangle mark of the housing.
(2) When the tool is used as a drill, align the drill mark "###" displayed on the cap to the triangle mark of the housing.
(3) When the tool is used as the impact drill, align the hammer mark "T" displayed on the cap to the triangle mark of the housing. (See Fig. 4.)

CAUTION

Align the number and mark on the cap to the triangle mark of the housing. The middle point of the numbers and marks on the cap cannot be secured.

2. Tightening torque adjustment

(1) Tightening torque
Tightening torque should correspond in its intensity to the screw diameter. When too strong power 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
Tightening torque should be changed according to the screw type and the materials to be tightened. Guidance of the tightening torque is indicated on the cap of this unit with numerals “1”, “2”, “3”, “4” and “5”. The minimum power is from “1” position and bigger the value the stronger is the power (see Fig. 4).
(3) How to adjust the tightening torque

Rotate the cap and set to one of the numerals.

Adjust the torque by cap rotation in such a way that when the torque is too strong, set to the next smaller numeral and set to the next larger numeral when too weak.

CAUTIONS

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

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

1. Rotation to Impact changeover (See Fig. 4.).

The "Rotation (Rotation only)" and "Impact (Impact + Rotation)" can be switched by aligning the drill

mark "dor the hammer mark" " to the triangle mark of the housing.

To make holes in the metal, wood or plastic, switch to "Rotation (Rotation only)".
○To make holes in bricks or concrete blocks, switch to "Impact (Impact + Rotation)".

CAUTION

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

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. 5 and 6).

When the shift knob is set to “L”, the drill rotates at a low speed. When set to “H”, 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 setting the shift knob to "H" (high speed) and the position of the cap is "4" or "5", it may happen that the clutch does not engage and that the motor is locked. In such a case, please set the shift knob to "L" (low speed).
○If the motor is locked, immediately turn the power off. If the motor is locked for a while, the motor or battery may be burnt.

5. The scope and suggestions for uses

The usable scope for various types of work based on the mechanical structure of this unit is shown

	Nut: 5 mm
	Wood screw: 5.1 mm (diameter) x 32 mm (length) Use after drilling a pilot hole.

6. How to select tightening power and rotational speed

Table 2

Use Cap Position			Rotating speed selection (Position of the shift knob)
			L (Low speed) H (High speed)
Driving	Machine screw 1 – 5		For 4 mm or smaller diameter screws.	For 5 mm or larger diameter screws.
	Wood screw 1 – 5 For 3.5 mm or smaller nominal diameter screws.			For 3.8 mm or larger nominal diameter screws.
Drilling	Brick ——			For drilling with a carbide tipped drill bit.
	Wood For 10 mm or larger diameters.			For 10 mm or smaller diameters.
	Metal		For drilling with a metal working drill bit.	——

CAUTION

☐ The selection examples shown in Table 2 should be considered as general standard. As different types of tightening screws and different materials to be tightened are used in actual works proper adjustments are naturally necessary.

7. Mounting and dismounting of the bit.

(1) Mounting the bit

After inserting a driver bit, etc. into the keyless drill chuck, firmly grasp the ring and tighten the sleeve by turning it toward the right (in the clockwise direction as viewed from the front). (See Fig. 7)

○If the sleeve becomes loose during operation, tighten it further. The tightening force becomes stronger when the sleeve is tightened.

(2) Dismounting the bit

Firmly grasp the ring and loosen the sleeve by turning it toward the left (in the counter-clockwise direction as viewed from the front). (See Fig. 7)

CAUTION:

When it is no longer possible to loosen the sleeve, use a vise or similar instrument to secure the bit. Set the clutch mode between 1 and 3 and then turn the sleeve to the loose side (left side) while operating the clutch. It should be easy now to loosen the sleeve.

8. Confirm that the battery is mounted correctly.

9. Check the rotational direction

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. 8). (The(L) and (R) marks are provided on the body.)

CAUTION:

Always use the impact drill with clockwise rotation, when using it as an impact drill.

10. Switch operation

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 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.

11. For drilling into brick

Excessive pressing force never increases drilling speed. It will not only damage the drill tip or reduce working efficiency, but could also shorten the service life of drill bit. Operate the impact drill within 10-15 kg pressing force while drilling into brick.

MAINTENANCE AND INSPECTION

1. Inspecting the tool

Since use of as dull tool will degrade efficiency and cause possible motor malfunction, sharpen or replace the tool as soon as abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

3. Cleaning on the outside

When the impact drill is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, for they melt plastics.

4. Storage

Store the impact drill in a place in which the temperature is less than 40^ C and out of reach of children.
