SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications provided
with this power tool. Failure to follow all instructions
listedbelowmayresultinelectricshock,reand/or
seriousinjury.
Save all warnings and instruc-
tions for future reference.
Theterm"powertool"inthewarningsreferstoyour
mains-operated(corded)powertoolorbattery-operated
(cordless)powertool.
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
whichmayignitethedustorfumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
youtolosecontrol.
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. Unmodiedplugsandmatchingoutletswill
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-
tricshockifyourbodyisearthedorgrounded.
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 inuence of drugs, alcohol or med-
ication. A moment of inattention while operating
powertoolsmayresultinseriouspersonalinjury.
2. Use personal protective equipment. Always
wear eye protection.Protectiveequipmentsuch
asadustmask,non-skidsafetyshoes,hardhator
hearing protection used for appropriate conditions
willreducepersonalinjuries.
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.Carryingpowertoolswith
yourngerontheswitchorenergisingpowertools
that have the switch on invites accidents.

4ENGLISH
4. Remove any adjusting key or wrench before
turning the power tool on.Awrenchorakeyleft
attachedtoarotatingpartofthepowertoolmay
resultinpersonalinjury.
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.Looseclothes,jewelleryor
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
causesevereinjurywithinafractionofasecond.
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
powertoolwilldothejobbetterandsaferatthe
rate for which it was designed.
2. Do not use the power tool if the switch does
not turn it on and o.Anypowertoolthatcannot
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.Suchpreventivesafetymeasuresreduce
theriskofstartingthepowertoolaccidentally.
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 aect the
power tool’s operation. If damaged, have the power
tool repaired before use.Manyaccidentsarecaused
bypoorlymaintainedpowertools.
6. Keep cutting tools sharp and clean.Properly
maintained cutting tools with sharp cutting edges

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
foroperationsdierentfromthoseintendedcould
result in a hazardous situation.
8.
Keep handles and grasping surfaces dry, clean
and free from oil and grease.Slipperyhandlesand
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 entanglement of cloth work
glovesinthemovingpartsmayresultinpersonalinjury.
Battery tool use and care
1. Recharge only with the charger specied by
the manufacturer. A charger that is suitable for
onetypeofbatterypackmaycreateariskofre
whenusedwithanotherbatterypack.
2. Use power tools only with specically desig-
nated battery packs.Useofanyotherbattery
packsmaycreateariskofinjuryandre.
3. 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.Shortingthebatterytermi-
nalstogethermaycauseburnsorare.
4.
Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact acci-
dentally occurs, ush with water. If liquid con-
tacts eyes, additionally seek medical help.Liquid

or rain.
A battery short can cause a large current
ow, overheating, possible burns and even a
breakdown.
6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50 °C (122 °F).
7. Do not incinerate the battery cartridge even if
it is severely damaged or is completely worn
out. The battery cartridge can explode in a re.

Tips for maintaining maximum
battery life
1.
Charge the battery cartridge before completely dis-
charged. Always stop tool operation and charge the
battery cartridge when you notice less tool power.
2.
Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3.

ture at 10 °C - 40 °C (50 °F - 104 °F). Let a hot
battery cartridge cool down before charging it.
4. Charge the battery cartridge if you do not use
it for a long period (more than six months).
