7.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. 9).

￿ 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. 9).

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.

8.Automatic spindle-lock mechanism

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

9.Confirm that the battery is mounted correctly10.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. 10). (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.

11. 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.

12.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.

13.Using the hook

CAUTION

￿When using the hook, pay sufficient attention so that the main equipment does not fall. If the tool falls, there is a risk of accident.

￿Do not attach the tip tool except phillips bit to the tool main unit when carrying the tool main unit with the hook suspended from a waist belt.

Injury may result if you carry the equipment suspended from the waist belt with sharp tipped components such as drill bit attached.

The hook can be installed on the right or left side and the angle can be adjusted in 5 steps between 0° and 80°.

(1)Operating the hook

(a)Pull out the hook toward you in the direction of arrow (A) and turn in the direction of arrow (B) (Fig. 11).

(b)The angle can be adjusted in 5 steps (0°, 20°, 40°, 60°, 80°).

Adjust the angle of the hook to the desired position for use.

(2)Switching the hook position

CAUTION

Incomplete installation of the hook may result in bodily injury when used.

(a)Securely hold the main unit and remove the screw using a slotted head screwdriver or a coin (Fig. 12).

(b)Remove the hook and spring (Fig. 13).

(c)Install the hook and spring on the other side and securely fasten with screw (Fig. 14).

NOTE

Pay attention to the spring orientation. Install the spring with larger diameter away from you (Fig. 14).

(3)Using the bit holder (Hook with bit holder)

￿Installing the bit

Slide the bit from the side, and then insert firmly until the groove on the bit locks in the protruded section of the hook.

￿Removing the bit

Securely hold the main unit and pull out the bit by

holding the tip with your thumb (Fig. 15).

CAUTION

￿Only Hitachi STANDARD ACCESSORIES phillips bit (No. 2 ⋅ 65L; Code No. 983006) may be used. Do not

use other bits since they may come loose.

(4)Using as an auxiliary light (Hook with light)

(a)Press the switch to turn off the light.

If forgotten, the light will turn off automatically after 15 minutes.

(b)The direction of the light can be adjusted within the range of hook positions 1 - 5 (Fig. 16).

￿ Lighting time

AAAAmanganese batteries: approx. 15 hrs. AAAA alkali batteries: approx. 30 hrs.

CAUTION

Do not look directly into the light.

Such actions could result in eye injury.

(5)Replacing the batteries (Hook with light)

(a)Loosen the hook screw with a phillips-head screwdriver (No. 1) (Fig. 17).

Remove the hook cover by pushing in the direction of the arrow (Fig. 18).

(b)Remove the old batteries and insert the new batteries. Align with the hook indications and position the plus (+) and minus (–) terminals correctly (Fig. 19).

(c)Align the indentation in the hook main body with the protuberance of the hook cover, press the hook cover in the direction opposite to that of the arrow shown in Fig. 18 and then tighten the screw. Use commercially available AAAA batteries (1.5 V).
