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 of 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
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 tires 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.
4

(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.
safety shoes, hard hat, or hearing protection 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 loss 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 form 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 hands 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 tool's 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 with 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.

HOW TO USE THE SCREW DRIVER
1. Switch operation and rotational speed adjustment
Bit rotational speed can be adjusted between 0–6000/min (W6VM) or 0–4500/min
(W6V4) or 0–3000/min (W6VA4) or 0–2600/min (W6VB3) or 0–1700/min (W8VB2)
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 6000/min (W6VM)
or 4500/min (W6V4) or 3000/min (W6V A4) or 2600/min (W6VB3) or 1700/min (W8VB2)
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 released. By
pulling the trigger switch again, the switch stopper disengages 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 and tightens 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 remove screws.
CAUTION
Never change the direction of hex-socket (or bit holder) 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 (or bit holder) rotation.
