WARNING! Read all instructions. Failure to follow all instructions listed below may result in electric shock fire and/or serious
injure. The term “power tool” in all of the warning listed below refers to your mains-operated (corded) power tool or battery operated
(cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area Safety
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive atmosphere, such as in the presence of flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust of fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2) Electrical Safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an
increased risk of electric shock if your body is earthed or grounded.
c) Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord to carry, pulling or unplugging the power tool. Keep cord away from heat, oil,
sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor
use reduces the risk of electric shock.
3) Personal Safety
a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use power tool while you
are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may
result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions will reduce personal injuries.
Rubber gloves and non-skid footwear are recommended when working outdoors.
c) Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your finger on
the switch or plugging in power tools that have the switch on invites accidents.
d) Remove any adjusting keys or wrench before turning the power tool on. A wrench or a key that is left attached to a rotating
part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected
situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving parts
g) Secure work. Use clamps or a vice to hold the work. It is safer than using your hand and frees
both hands to operate the tool.
h) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and
properly used. Use of these devices can reduce dust-related hazards.
i) Use a safety device. Wear protective earmuffs to reduce personal injury.
4) Power tool Use and Care
a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and
safer at the rate for which it was designed.
b) Do not use power tool if switch does not turn it on / off. Any power tool that cannot be controlled with the switch is dangerous
and must be repaired.
c) Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the power tools.
Such preventive safety measures reduce the risk of starting the power tool accidentally.

instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
Do not let visitors touch the tool or extension cord. All visitors should be kept away from work area.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that
may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
Inspect extension cords periodically and replace, if damaged.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are
easier to control.
g) Use the power tools, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the
particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power
tool for operations different from intended could result in a hazardous situation.

WARNING！
DO NOT OPERATE THIS TOOL WITHOUT
PROTECTIVE EARTH CONNECTED
1、This tool should be grounded while in use to protect the operator from electric shock. NOTICE! To ensure the grounding result,
the grounding conductor of the power cord must be well connected with the grounding terminal of power facility. This tool is
equipped with grounding conductors. The Green (or Green and Yellow) conductor in the Power Cord is the grounding wire.
Never connect Green (or Green and Yellow) to a live terminal. The grounding wires in this tool can not only earth the electric
leakage safely, but also can eliminate ESD-the electrostatic that tool occurred while in use.
2、The grounding is the most important task for a user. Periodically, depends on the working condition and circumstance, for
maintaining a good function, the user has to check the grounding condition every 3~6 months by an electric meter and following
simple steps; Set the Ohm meter to level R*10(Ohm). Touching 2 test rods (“＋”＆”－”) together and reset the meter to “0”.
Using the Red(“＋”) rod to touch the Grounding wire on the Plug of controller’s cord, and the Black(“－”) rod to the end of Bit
Head. It stands for the grounding is normal if the meter is read as close as to “0”. For getting a normal indication on the meter
while in testing, need to press the test rods firmly to the testing objects.
3、The instrument QC of the tool is performed before the tool ex-factory. The grounding continuity test is conducted by input 8A or
25A current (depends on the model) to the end of earth terminal, and subject to the resistance value lower than 0.5(Input 8A
current) or 0.1(Input 25A current) Ohm.

To adjust the torque on these screwdrivers. Proceed as follows:
1. Determine the torque output of the tool by checking a tightened fastener with a torque wrench.
2. Increase or decrease the torque by turning the torque adjusting nut on the nose of the driver. Turning the nut clockwise to a
higher number on the torque scale increase torque output while rotating the nut counterclockwise to a lower number decreases
the torque output.
3. Check the adjustment with a torque wrench. A number of factors will affect torque output from one job to another. Final torque
adjustment should be made at the job through a series of gradual increase. Always start below the desired torque and work
upward.
4. Adjust the bit torque by changing the driving in length of the adjust nut at the end.
5. The relationship between torque scale on nut and bit torque is as shown in the torque diagram. The figures of torque scale do not
indicate bit torque actual values. However, the clamping torque of screw itself is different form type, size, material of the screw
and the material of its mating part. Use it as standard to obtain an appropriate clamping torque.
6. The (Return torque method) in which once-clamped screw is returned with torque wrench or the like is available as one of torque
control methods, however, note that the measured values by the return torque method generally appear in 10%~30% lower than
the actually clamping torque.
7. The torque tester measures the torque of screwdriver. The clamping torque of screw itself is different from the clamped
conditions. Understand the correlation between clamping torque values and the torque tester values perform the torque control
properly.
1. Also in reverse rotation, the clutch is shut-off in such manner as in normal rotation, stopping the motor running accordingly,
when the screw tightened at a large torque, set it to a higher torque scale.
2. The numbers from zero to eight on the torque scale are reference number only and not an indication of actual torque output.
3. Please refer to KILEWS website http://www.kilews.com.tw for the detail component list.
