◯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. 9).
(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. 10).
(b)Remove the hook and spring (Fig. 11).
(c)Install the hook and spring on the other side and
securely fasten with screw (Fig. 12).
NOTE
Pay attention to the spring orientation. Install the spring with larger diameter away from you (Fig. 12).
(3)Using the bit holder ◯ Installing the bit
Slide the bit from the side in the direction of Fig. 13, 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. 14).
CAUTION
◯ The bit may come loose from the hook and cause bodily injury when reversing the direction of the bit as shown in Fig. 13 or when using the driver with the bit stored incomplete.
◯ Only Hitachi OPTIONAL ACCESSORIES plus driver bits (Bit No. 2; Code No. 992671, Bit No. 3; Code No. 992672) may be used. Do not use other bits since they may come loose.
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. 15).
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. 15).
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 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.
8.Automatic
This unit has automatic
9.Confirm that the battery is mounted correctly
10.Check the rotational direction
The bit rotates clockwise (viewed from the rear side) by pushing the
the bit counterclockwise (See Fig. 16) (The L and R marks are provided on the body).
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.
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. 17)
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 whthin the brush holders.
NOTE
When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No. 999054.
