GENERAL POWER TOOL
SAFETY WARNINGS
WARNING
Read all safety warnings, instruc-
tions, illustrations and specica-
tions 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 instructions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-oper-
ated (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 atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operat-
ing 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. Unmodied 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 condi-
tions. 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 an 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 inuence 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 o󰀨-position before connecting to power
source and/or battery, picking up or carrying
the tool. Carrying power tools with your nger 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.
•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
jewelry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry 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 o󰀨. 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, 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 a󰀨ect 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 di󰀨erent from those intended 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 specied by the
manufacturer. A charger that is suitable for one
type of battery may create a risk of re when used
with another battery.
• Use power tools only with specically designated
battery. Use of any other battery may create a risk
of injury and re.

3
• When battery 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 re.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact ac-
cidentally 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 or tool that is damaged or
modied. Damaged or modied batteries may exhibit
unpredictable behavior resulting in re, explosion or
risk of injury.
• Do not expose a battery or tool to re or exces-
sive temperature. Exposure to re or temperature
above 265°F (130°C) may cause explosion.
•Follow all charging instructions and do not charge
the battery or tool outside the temperature range
specied in the instructions. Charging improperly
or at temperatures outside the specied range may
damage the battery and increase the risk of re.
