General Safety Rules
Warning! Read and understand all
instructions. Failure to follow all
instructions listed below may result
in electric shock, re and/or serious
personal injury.
PLEASE SAVE THESE INSTRUCTIONS!
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
operating a power tool. Distractions can cause
you to lose control.
Electrical Safety
Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase
the risk of damage.
Personal Safety
• Always wear eye protection. Care must be
taken to prevent chips from hitting other
workers in the same area.
• 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 dust mask, non-skid safety shoes,
hard hat, or hearing protection used for ap-
propriate conditions will reduce personal
injuries.
• 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 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 con-
trol of the power tool in unexpected situa-
tions.
• Dress properly. Do not wear loose cloth-
ing or jewelry. Keep your hair, clothing and
gloves 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.
• Keep ngers and body parts away from the
blade opening.
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 dan-
gerous and must be repaired.
• Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing ac-

cessories, or storing power tools. Such preven-
tive safety measures reduce the risk of starting
the power tool accidentally.
• 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.
• Maintain power tools. 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 acci-
dents 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 blades
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.
Service
Have your power tool serviced only by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
