NOTE

The charging time may vary according to temperature and power source voltage.

1. Disconnect the charger's power cord from the receptacle

2. Hold the charger firmly and pull out the battery NOTE

After operation, pull out batteries from the charger first, and then keep the batteries properly.

How to make the batteries perform longer.

(1) Recharge the batteries before they become completely exhausted.

When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.

(2) Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

CAUTION

When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging.

○If the battery is recharged when it is warm due to battery use or exposure to sunlight, the pilot lamp map light in green.

The battery will not be recharged. In such a case, let the battery cool before charging.

When the pilot lamp flickers in red (at 0.2-second intervals), check for and take out any foreign objects in the charger's battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

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. 5)

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 black dots, with the triangle mark on the outer body.

(2) When using this unit as a drill, align the cap drill mark "###" 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.

CAUTION

○The cap cannot be set between the numerals "1, 3, 5 ... 22" or the black dots.

○Do not use with the cap 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, 3, 5 ... 22" on the cap, and the black dots. The tightening torque at position "1" is the weakest and the torque is strongest at the highest number (See Fig. 5).

(3) Adjusting the tightening torque

Rotate the cap and line up the numbers "1, 3, 5 ... 22" on the cap, or the black 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.

CAUTION

☐The motor rotation may be locked to cease while the unit is used as drill. While operating the impact driver 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 "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. 7 and 8).

When the shift knob is set to "LOW", the drill rotates at a low speed.!»en 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 between "17" and "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 4.

Table 4

Work Suggestions
Drilling	Brick	Use for drilling purpose.
	Wood
	Steel
	Aluminum
Driving	Machine screw Use the	bit or socket matching the screw diameter.
	Wood screw Use after drilling a pilot hole.

6. How to select tightening torque and rotational speed

Table 5

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 screws.	For 6 mm or smaller diameter screws.
	Wood screw 1 -		For 6.8 mm or smaller nominal diameter screws.	For 3.8 mm or smaller nominal diameter screws.
Drilling	Brick		For 13 mm or smaller diameters.	For 10 mm or smaller diameters.
	Wood		For 36 mm or smaller diameters.	For 18 mm or smaller diameters.
	Metal		For drilling with a metal working drill bit.	—

CAUTION

☐ The selection examples shown in Table 5 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 driver 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 driver drill at LOW (low speed) when using a machine screw.

NOTE

The use of the Li-ion battery in a cold condition (below 0 degree Centigrade) can sometimes result in the weakened tightening torque and reduced amount of work. This, however, is a temporary phenomenon, and returns to normal when the battery warms up.

7. Using the hook

The hook is used to hang up the power tool to your waist belt while working.

CAUTION:

When using the hook, hang up the power tool firmly not to drop accidentally. If the power tool is dropped, it may lead to an accident.

When carrying the power tool with hooked to your waist belt, do not fit any bit to the tip of power tool. If the sharp bit such as drill is fitted to the power tool when carrying it with hooked to your waist belt, you will be injured.

○Install securely the hook. Unless the hook is securely installed, it may cause an injury while using.

(1) Removing the hook.

Remove the screws fixing the hook with Philips screw driver. (Fig. 9)

(2) Replacing the hook and tightening the screws.

Install securely the hook in the groove of power tool and tighten the screws to fix the hook firmly. (Fig. 10)

8. About Remaining Battery Indicator

When pressing the remaining battery indicator switch, the remaining battery indicator lamp lights and the battery remaining power can be checked. (Fig.11) When releasing your finger from the remaining battery indicator switch, the remaining battery indicator lamp goes off. The table 6 shows the state of remaining battery indicator lamp and the battery remaining power.

Table 6

State of lamp	Battery Remaining Power
[TCWK]	The battery remaining power is enough.
	The battery remaining power is a half.
	The battery remaining power is nearly empty.Re-charge the battery soonest possible.

As the remaining battery indicator shows somewhat differently depending on ambient temperature and battery characteristics, read it as a reference.

NOTE:

○Do not give a strong shock to the switch panel or break it. It may lead to a trouble.
To save the battery power consumption, the remaining battery indicator lamp lights while pressing the remaining battery indicator switch.

9. How to use the LED light

Every time you press the light switch on the switch panel, the LED light lights or goes off. (Fig. 12) To prevent the battery power consumption, turn off the LED light frequently.

CAUTION:

○Do not expose directly your eye to the light by looking into the light.
If your eye is continuously exposed to the light, your eye will be hurt.

NOTE:

To prevent the battery power consumption caused by forgetting to turn off the LED light, the light goes off automatically in about 15 minutes.

10. Mounting and dismounting of the bit

(1) Mounting the bit

Loosen the sleeve by turning it toward the left (in the counterclockwise direction as viewed from the front) to open the clip on the keyless chuck. After inserting a driver bit, etc., into the keyless drill chuck, and tighten the sleeve by turning it toward the right (in the clockwise direction as viewed from the front) (See Fig. 13).

○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

Loosen the sleeve by turning it toward the left (in the counterclockwise direction as viewed from the front), and then take out the bit, etc. (See Fig. 13).

NOTE

If the sleeve is tightened in a state where the clip of the keyless chuck is opened to a maximum limit, a click noise may occur. This is the noise that occurs when the loosening of the keyless chuck is prevented and is not a malfunction.

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

11. Automatic spindle-lock mechanism

This unit has automatic spindle-lock mechanism for quick bit changes.

12. Confirm that the battery is mounted correctly

13. 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. 14). (The (L) and (R) marks are provided on the selector button.)

CAUTION

○Always use this unit with clockwise rotation, when using it as an impact drill.

14. 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 switch 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.

15. 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 driver 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. Maintenance of the motor

The motor unit winding is the very "heart" of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

4. Inspecting the carbon brushes (Fig. 15)

The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones when it becomes worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

NOTE

When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No. 999054.

5. Replacing carbon brushes

Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a flat head screw driver, etc., as shown in Fig. 17.

When installing the carbon brush, choose the direction so that the nail of the carbon brush agrees with the contact portion outside the brush tube. Then push it in with a finger as illustrated in Fig. 18. Lastly, install the brush cap.

CAUTION

Be absolutely sure to insert the nail of the carbon brush into the contact portion outside the brush tube. (You can insert whichever one of the two nails provided.)

Caution must be exercised since any error in this operation can result in the deformed nail of the carbon brush and may cause motor trouble at an early stage.

6. Cleaning on the outside

When the Impact driver 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.

7. Storage
