NOTE emphasizes essential information.
SAFETY
GENERAL SAFETY RULES
WARNING: Read and understand all instructions.
Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
1. Work Area
(1) Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
(2) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
(3) Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.
2. Electrical Safety
(1) Double Insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double Insulation eliminates the need for the three wire grounded power cord and grounded power supply system.
(2) Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
(3) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
(4) Do not abuse the cord. Never use the cord to carry the tools or pull the plug from a receptacle. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
(5) When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W". These cords are rated for outdoor use and reduce the risk of electric shock.
3. Personal Safety
(1) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
(2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
(3) Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.
(4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.
(5) Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
(6) Use safety equipment. Always wear protective grasses. Dust mask, non-skid safety shoes, hard hat, or ear plugs must be used for appropriate conditions.
4. Tool Use and Care
(1) Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to lose of control.
(2) Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
(3) Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
(4) Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
(5) Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hand of untrained users.
(6) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control.
(7) Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
(8) Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.
5. Service
(1) Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
(2) When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instruction may create a risk of electric shock or injury.
- Never touch moving parts.
Never place your hands, fingers or other body parts near the tool's moving parts.
- Never operate without all guards in place.
Never operate this tool without all guards or safety features in place and in proper working order. If maintenance or servicing requires the removal of a guard or safety feature, be sure to replace the guard or safety feature before resuming operation of the tool.
- Use right tool.
Don't force small tool or attachment to do the job of a heavy-duty tool.

Cracks in the tool's housing or handle can lead to electric shock. Such tools should not be used until repaired.
13.Blades and accessories must be securely mounted to the tool.
Prevent potential injuries to yourself or others. Blades, cutting implements and accessories which have been mounted to the tool should be secure and tight.
- Keep motor air vent clean.
The tool's motor air vent must be kept clean so that air can freely flow at all times. Check for dust build-up frequently.
15.Operate power tools at the rated voltage.
Operate the power tool at voltages specified on its nameplate.
If using the power tool at a higher voltage than the rated voltage, it will result in abnormally fast motor revolution and may damage the unit and the motor may burn out.
16.Never use a tool which is defective or operating abnormally.
If the tool appears to be operating unusually, making strange noises, or otherwise appears defective, stop using it immediately and arrange for repairs by a Hitachi authorized service center.
17.Never leave tool running unattended. Turn power off.
Don't leave tool until it comes to a complete stop.
18.Carefully handle power tools.
Should a power tool be dropped or struck against hard materials inadvertently, it may be deformed, cracked, or damaged.
19.Do not wipe plastic parts with solvent.
Solvents such as gasolie, thinner, benzine, carbon tetrachloride, and alcohol may damage and crack plastic parts. Do not wipe them with such solvents.
Wipe plastic parts with a soft cloth lightly dampened with soapy water and dry thoroughly.
SPECIFIC SAFETY RULES AND SYMBOLS
- Hold tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator.
- Wear ear plugs when using the tool for extended periods. Prolonged exposure to high intensity noise can cause hearing loss.
- Employ a driver bit appropriate for the screw diameter.
- Apply the screw driver body perpendicularly to a screw head when driving a screw.

To ensure safer operation of this power tool, HITACHI has adopted a double insulation design. "Double insulation" means that two physically separated insulation systems have been used to insulate the electrically conductive materials connected to the power supply from the outer frame handled by the operator. Therefore, either the symbol "□" or the words and "Double insulation" appear on the power tool or on the nameplate.
Although this system has no external grounding, you must still follow the normal electrical safety precautions given in this Instruction Manual, including not using the power tool in wet environments.
To keep the double insulation system effective, follow these precautions:
Only HITACHI AUTHORIZATIONED SERVICE CENTER should disassemble or assemble this power tool, and only genuine HITACHI replacement parts should be installed.
Clean the exterior of the power tool only with a soft cloth moistened with soapy water, and dry thoroughly.
Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve.

O Tightening Drywall screws, wood screws and self-drilling screws
NOTE:
For tightening the Self-drilling screws, sub-stopper (B) and non-magnetic bit holder (sold separately) are recommended.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms to the power source requirements specified on the product nameplate.
2. Power switch
Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while the switch is in the ON position, the power tool will start operating immediately and can cause serious injury.
3. Extension cord
When the work area is far away from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.
WARNING: Damaged cord must be replaced or repaired.
4. Check the receptacle
If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs.
If such a faintly receptacle is used, it may cause overheating, resulting in a serious hazard.
5. Confirming condition of the environment:
Confirm that the work site is placed under appropriate conditions conforming to prescribed precautions.
6. Confirm the direction of bit rotation (Fig. 2)
The bit rotates clockwise (viewed from the rear side) when the reversing switch lever is set to the "R" side position. When the lever is set to the "L" side position, the bit rotates counterclockwise and can be used to loosen and retract screws.
CAUTION:
Never change the bit rotating direction while operating the Screw Driver. Turn the main switch off before changing the rotating direction, otherwise, burning of the motor will result.
7. Adjusting the tightening depth (Fig. 3)
Pull the lock sleeve in the direction of arrow to remove it from the spline installed in the gear cover.
While pulling the lock sleeve and turning it right and left, adjust the position of locator. Push the lock sleeve and align the gear cover spline with the lock sleeve spline.
The lock sleeve is inserted onto the gear cover spline and locked.
(1) For hex-head screws (Fig. 4)

HOW TO USE THE SCREW DRIVER
1. Switch operation and rotational speed adjustment
Bit rotational speed can be regulated between 0 - 2600/min (W6VB2) or 0 - 1700/min (W8VB) varying the degree by which the trigger switch is pulled. Rotational speed increases as the trigger switch is pulled, and reaches a maximum speed of 2600/min (W6VB2) or 1700/min (W8VB) when the trigger switch is pulled fully.
To facilitate continuous operation, pull the trigger switch and depress the switch stopper. The switch will then remain ON even when the finger is removed. By pulling the trigger switch again, the switch stopper is disengaged and the switch is turned OFF when the trigger switch is released.
2. Screw driver operation
When the switch is turned ON, the motor starts to run but the hex-socket (or the bit) does not rotate. Attach the hex-socket to the screw head groove, and push the screw driver against the screw. The hex-socket then rotates, tightening the screw.
CAUTION
Ensure that the screw driver is held truly perpendicular to the head of the screw. If held at an angle, the driving force will not be fully transferred to the screw, and the screw head and/or hex-socket will be damaged. Hex-socket rotation stops when pushing force is released.
3. Direction of hex-socket rotation
The hex-socket rotates clockwise (viewed from the rear side) when the reversing switch lever is set to the "R" side position. When the lever is set to the "L" side position, the hex-socket rotates counterclockwise, and can be used to loosen and retract screws.
CAUTION
Never change the direction of hex-socket rotation while the motor is running. To do so would seriously damage the motor. Turn the power switch OFF before changing the direction of hex-socket rotation.
- Tightening Self-drilling screw
When the supplied magnet bit holder is used to tighten the Self-drilling screw into a steel plate, cut material stuck in the magnet bit will degrade the work efficiency.
To prevent this, the non-magnetic bit holder (optional accessory) is recommended. The stainless locator with bushing (optional accessory) will prevent the bushing from being worn.
MOUNTING AND DISmountING THE HEX-SOCKET OR THE BIT
CAUTION
Be sure to switch power OFF and disconnect the plug from receptacle to avoid serious trouble.
- Dismounting the hex-socket (Fig. 7)
(1) While rotating the Sub-Stopper pull it out from the locator.
(2) Remove the hex-socket, hold it with the opposite side of bit with hand or vise and pull out the bit with pliers. - Dismounting the bit (Fig. 8)
Remove the sub-stopper (A) alike case of hex-head socket and remove the bit holder, then pull out the bit with pliers.
- Dismounting the bit (Fig. 9)
Remove the sub-stopper (C) alike case of hex-head socket and remove the bit holder, then pull out the bit with pliers.
- Mounting the hex-socket or the bit Install the bit in the reverse order to remove.
