•
Some dust created by power sanding, sawing, grinding,
drilling and other construction activities contains
chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
–
Lead from lead-based paints.
–
Crystalline silica from bricks, cement, and other
masonry products.
–
Arsenic and chromium from chemically-treated
lumber.
•
Your risk from these exposures varies, depending upon
how often you do this type of work. To reduce your
exposure to these chemicals:
–
Work in a well-ventilated area.
–
Work with approved safety equipment, such as dust
masks that are specially designed to filter out
microscopic particles.
–
Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing
dust to get into your mouth or eyes or to lie on the skin
may promote absorption of harmful chemicals.
GENERAL SAFETY WARNINGS
Read all safety warnings,
instructions, illustrations and
specifications provided with this power tool. Failure
to follow all instructions listed below may result in
electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND
INSTRUCTIONS FOR FUTURE REFERENCE.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-
operated (cordless) power tool.
WORK AREA SAFETY
•Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
•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.
•Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
ELECTRICAL SAFETY
•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.
•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.
•Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
•Do not abuse the cord. Never use the cord for
carrying, 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.
•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.
•If operating a power tool in a damp location is
unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of a GFCI
reduces the risk of electric shock.
PERSONAL SAFETY
•Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a 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.
•Use personal protective equipment. Always wear
eye protection. Protective equipment such as a
dust mask, non-skid safety shoes, hard hat or
hearing protection used for appropriate
conditions will reduce personal injuries.
•Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on
the switch or energizing power tools that have
the switch on invites accidents.
•Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.

3
•Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
•Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
•If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust- related hazards.
•Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
•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.
•Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
•Disconnect the plug from the power source
and/or remove the battery pack, if detachable,
from the power tool before making any
adjustments, changing accessories, or storing
power tools. Such preventive safety measures
reduce the risk of starting the power tool
accidentally.
•Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the
hands of untrained users.
•Maintain power tools and accessories. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition that
may affect the power tool's operation. If
damaged, have the power tool repaired before
use. Many accidents are caused by poorly
maintained power tools.
•Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
•Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to
be performed. Use of the power tool for
operations different from those intendeds could
result in a hazardous situation.
•Keep handles and grasping surfaces dry, clean
and free from oil and grease.
•Slippery handles and grasping surfaces do not
allow for safe handling and control of the tool in
unexpected situations.
BATTERY TOOL USE AND CARE
•Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one
type of battery pack may create a risk of fire
when used with another battery pack.
•Use power tools only with specifically designated
battery packs. Use of any other battery packs
may create a risk of injury and fire.
•When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together
may cause burns or a fire.
•Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause
irritation or burns.
•Do not use a battery pack or tool that is damaged
or modified. Damaged or modified batteries may
exhibit unpredictable behaviour resulting in fire,
explosion or risk of injury.
•Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or
temperature above 265 °F may cause explosion.
•Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specified in the instructions.
Charging improperly or at temperatures outside
the specified range may damage the battery and
increase the risk of fire.
SERVICE
•Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
•Never service damaged battery packs. Service of
battery packs should only be performed by the
manufacturer or authorized service providers.
SAFETY WARNINGS FOR IMPACT WRENCH
•Hold the power tool by insulated gripping
surfaces, when performing an operation where
the fastener may contact hidden wiring.
Fasteners contacting a "live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.

VARIABLE-SPEED TRIGGER SWITCH
See Fig. 5
Your tool is equipped with a variable-speed trigger
switch. The tool can be turned "ON" or "OFF" by
depressing or releasing the trigger.
The variable-speed trigger switch delivers high- er
speed with increased trigger pressure and lower
speed with decreased trigger pressure.
CHANGING THE IMPACT FORCE MODE
See Fig. 6,7
a.When the bit rotates clockwise (forward direction),
you can change the impact force among 3 modes
(low / mid / high) (Fig. 6). This allows a tightening
force suitable to the work. Each time you press the
red MODE button, the mode program will be
switched to low mode, mid mode and high mode.
·Indicator light "L" shines green to indicate "low-
speed mode".
·Indicator light "M" shines green to indicate
"mid-speed mode".
·Indicator light "H" shine green to indicate "high-
speed mode".
b.When the bit rotates counterclockwise (reverse),
you can change the impact force among two
modes (Reverse Rotation Auto-stop Mode /
Standard Mode). (Fig. 7)
The innovative Reverse Rotation Auto-stop Mode
stops rotation and impact when fastener is
loosened adequately. This prevents the nut from
falling off the bolt.
Press the Mode button to toggle between the two
functions.
·Indicator light "RAS" shines green to indicate
"Reverse Rotation Auto-stop Mode".
In Reverse Rotation Auto-stop Mode, if the
IMPACT WRENCH does not feel enough
resistance, it will only rotation a few circles and
then stop, such as rotation at no load. Otherwise,
it will continue to run until the resistance is very
low.
·All Indicator light are off, indicating "Standard
mode". This mode allows the IMPACT WRENCH
run at full speed and high impact frequency.
NOTICE: The impact force mode can be changed only
when the trigger switch is not depressed. The impact
force mode cannot be activated when the motor is
running.
The impact force mode will be stored and applied in
the next operation when the tool is turned on again
or when the direction of rotation has been changed.
Reset the impact modes as desired.
