CAUTION

If the battery is heated due to direct sunlight, etc., just after operation, the charger pilot lamp may not light up. At that time cool the battery first, then start charging.

1. Disconnect the charger power cord from the receptacle.
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 (see Fig. 4)

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

(1) When using this unit as a screwdriver, line up the one of the numbers “1, 3, 5 ... 22” on the cap, or the white dots, with the triangle mark on the outer body.
(2) When using this unit as a drill, align the cap drill mark “AID” with the triangle mark on the outer body.
(3) When using this unit as an impact drill, align the cap hammer mark "T" with the triangle mark on the outer body.

CAUTIONS

○The cap cannot be set between the numerals “1, 3, 5 ... 22” or the white dots.

○Do not use with the cap numeral between “22” and the white line at the middle of the drill mark. Doing so may cause damage. (See Fig. 5)

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, 3, 5 ... 22” on the cap, and a white dots. The tightening torque at position “1” is the weakest and the torque is strongest at the highest number. (See Fig. 4)

(3) Adjusting the tightening torque

Rotate the cap and line up the numbers “1, 3, 5, ... 22” on the cap, or the white dots, with the triangle mark on the outer body. Adjust the cap in the weak or the strong torque direction according to the torque you need.

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.

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

The “Rotation (Rotation only)” and “Impact (Impact + Rotation)” can be switched by aligning the drill mark “◀” or the hammer mark “T” 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 "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. 6 and 7).

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 setting the shift knob to “HIGH” (high speed) and the position of the cap is “17” or “22”, 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 “LOW” (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 in Table.1.

Table 1

Work Suggestions
Drilling	Brick	Use for drilling purpose.
	Wood
	Steel
	Aluminum
Driving	Machine screw Use the bit and socket matching the screw diameter.
	Wood screw 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)
			LOW (Low speed)	HIGH (High speed)
Driving	Machine screw	1 — 22	For 4 mm or smaller diameter screw.	For 6 mm or smaller diameter screw.
	Wood screw	1 —	For 5.1 mm or smaller nominal diameter screw.	For 3.8 mm or smaller nominal diameter screw.
Drilling Wood	Brick	T	—	For drilling with a carbide tipped drill bit.
	Wood	I	For 18 mm or smaller diameters.	For 18 mm or smaller diameters.
	Metal	I	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.

When using the impact drill with a machine screw at HIGH (high speed), a screw may damage or a bit may lose due to the tightening torque is too strong. Use the impact drill at LOW (low speed) when using a machine screw.

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. 8)

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

(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. 8)

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 11 and then turn the sleeve to the loose side (left side) while operating the clutch. It should be easy now to loosen the sleeve.

NOTE

○There is a plus driver bit on side of the main unit. The bit can be removed by pulling it forward. After using the bit, make sure to firmly attach it to the main body again.

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

CAUTION:

Always use this unit 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.

NOTE

○A buzzing noise is produced when the motor is about to rotate; This is only a noise, not a machine failure.

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.

12. Using the hook

The provided hook is so designed that it can be installed and removed on either right or left by one touch.

Use it correctly as occasion demands.

(1) Installing the hook

To begin with, remove the battery from the tool. Subsequently, insert the hook so that the grooves at 2 locations of the hook and the 2 protrusions of the hook installing part of the tool come together, check and confirm that the hook is securely fixed, and then install the battery. (See Figs. 10 and 11)

(2) Removing the hook

Remove the hook following the order of installation in reverse.

CAUTION

○Fix the hook securely before use. Any use with imperfect installation of the hook as is can result in injuries.

When you use the hook, be absolutely sure that it is in a state where the battery is installed. If you use it in a state where the battery is removed, the hook can come off or drop and result in injuries.

When you carry it hanging on a waist belt, do not install it on the drill chuck, but you can do so on the driver bit. If drills and the like with a sharp point are installed, injuries can result.

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.
