SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications provided
with this power tool. Failure to follow all instructions
listedbelowmayresultinelectricshock,reand/or
seriousinjury.
Save all warnings and instruc-
tions 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
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
whichmayignitethedustorfumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
youtolosecontrol.
Electrical safety
1. 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. Unmodiedplugsandmatchingoutletswill
reduce risk of electric shock.
2. Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tricshockifyourbodyisearthedorgrounded.
3. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
4. 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.
5.
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.
6. If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
7. Power tools can produce electromagnetic
elds (EMF) that are not harmful to the user.
However, users of pacemakers and other similar
medical devices should contact the maker of their
device and/or doctor for advice before operating
this power tool.
Personal safety
1. 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 inuence of drugs, alcohol or med-
ication. A moment of inattention while operating
powertoolsmayresultinseriouspersonalinjury.
2. 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.
3. Prevent unintentional starting. Ensure the
switch is in the o󰀨-position before connecting
to power source and/or battery pack, picking
up or carrying the tool.Carryingpowertoolswith
yourngerontheswitchorenergisingpowertools
that have the switch on invites accidents.
4. 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.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away
from moving parts.Looseclothes,jewelleryor
long hair can be caught in moving parts.
7. 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.

8.
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.
9. Always wear protective goggles to protect
your eyes from injury when using power tools.
The goggles must comply with ANSI Z87.1 in
the USA, EN 166 in Europe, or AS/NZS 1336
in Australia/New Zealand. In Australia/New
Zealand, it is legally required to wear a face
shield to protect your face, too.
It is an employer's responsibility to enforce
the use of appropriate safety protective equip-
ments by the tool operators and by other per-
sons in the immediate working area.
Power tool use and care
1. 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.
2. Do not use the power tool if the switch does
not turn it on and o󰀨.Anypowertoolthatcannot
be controlled with the switch is dangerous and
must be repaired.
3. Disconnect the plug from the power source
and/or remove the battery pack, if detachable,
from the power tool before making any adjust-
ments, changing accessories, or storing power
tools.Suchpreventivesafetymeasuresreduce
theriskofstartingthepowertoolaccidentally.
4. Store idle power tools out of the reach of chil-
dren 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.
5. Maintain power tools and accessories. Check
for misalignment or binding of moving parts,
breakage of parts and any other condition that
may a󰀨ect the power tool’s operation. If dam-
aged, have the power tool repaired before use.
Manyaccidentsarecausedbypoorlymaintained
power tools.
6. Keep cutting tools sharp and clean.Properly
maintained cutting tools with sharp cutting edges
arelesslikelytobindandareeasiertocontrol.
7. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing into account the working conditions and
the work to be performed. Use of the power tool
foroperationsdi󰀨erentfromthoseintendedcould
result in a hazardous situation.
8.
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.
9. When using the tool, do not wear cloth work
gloves which may be entangled. The entangle-
mentofclothworkglovesinthemovingpartsmay

Holdthetoolrmlyandplacethepointofthedriverbit
inthescrewhead.Applyforwardpressuretothetoolto
theextentthatthebitwillnotslipo󰀨thescrewandturn
the tool on to start operation.
NOTICE: If you use a spare battery to continue
the operation, rest the tool at least 15 min.
NOTE: Use the proper bit for the head of the screw/
boltthatyouwishtouse.
NOTE: When fastening M8 or smaller screw, choose
aproperimpactforceandcarefullyadjustpressureon
the switch trigger so that the screw is not damaged.
NOTE: Hold the tool pointed straight at the screw.
NOTE:Iftheimpactforceistoostrongoryoutighten
thescrewforatimelongerthanshowninthegures,
thescreworthepointofthedriverbitmaybeover-
stressed,stripped,damaged,etc.Beforestartingyour
job,alwaysperformatestoperationtodeterminethe
properfasteningtimeforyourscrew.
Thefasteningtorqueisa󰀨ectedbyawidevarietyof
factorsincludingthefollowing.Afterfastening,always
check the torque with a torque wrench.
1. Whenthebatterycartridgeisdischargedalmost
completely,voltagewilldropandthefastening
torque will be reduced.
2. Driver bit or socket bit
Failure to use the correct size driver bit or socket
bit will cause a reduction in the fastening torque.

3. Bolt
• Eventhoughthetorquecoe󰀩cientandthe
class of bolt are the same, the proper fasten-
ingtorquewilldi󰀨eraccordingtothediame-
ter of bolt.
Even though the diameters of bolts are the
same,theproperfasteningtorquewilldi󰀨er
accordingtothetorquecoe󰀩cient,theclass
of bolt and the bolt length.
4. The manner of holding the tool or the material
ofdrivingpositiontobefastenedwilla󰀨ectthe
torque.
5. Operating the tool at low speed will cause a reduc-
tion in the fastening torque.
