General power tool safety warnings
WARNING: Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions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.
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 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 off-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, clothing, and gloves
away from moving parts.Looseclothes,jewel-
lery 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.
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 off.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 the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such pre-
ventive 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. 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.
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 different from those intended could
result in a hazardous situation.
Battery tool use and care
1. Recharge only with the charger specied by
the manufacturer.Achargerthatissuitablefor
onetypeofbatterypackmaycreateariskofre
when used with another battery pack.
2. Use power tools only with specically desig-
nated battery packs. Use of any other battery
packsmaycreateariskofinjuryandre.
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. Shorting the battery

4ENGLISH
terminalstogethermaycauseburnsorare.
4. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If con-
tact accidentally occurs, ush with water. If
liquid contacts eyes, additionally seek medical
help.Liquidejectedfromthebatterymaycause
irritation or burns.
Service
1. Have your power tool serviced by a qualied
repair person using only identical replacement
parts.Thiswillensurethatthesafetyofthepower
tool is maintained.
2. Follow instruction for lubricating and chang-
ing accessories.
3. Keep handles dry, clean and free from oil and
grease.
