IMPORTANT SAFETY INFORMATION
General Power Tool Safety Warnings
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, fire 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.
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
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
Never modify the plug in any way.
Do not use any adapter plugs with grounded
power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
2� Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is grounded.
3� Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase 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
influence of drugs, alcohol or medication.
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 Trigger is in the off-position before
connecting to power source, picking up or
carrying the tool.
Carrying power tools with your finger on
the Trigger or energizing power tools that
have the Trigger on invites accidents.
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 Ground Fault Circuit
Interrupter (GFCI) protected supply.
Use of a GFCI reduces the risk of electric shock.
4� Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
5� Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry
or long hair can be caught in moving parts.
6� 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.
7� Only use safety equipment that has been
approved by an appropriate standards agency.
Unapproved safety equipment may not provide
adequate protection. Eye protection must be
ANSI-approved and breathing protection
must be NIOSH-approved for the
specific hazards in the work 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 Trigger
does not turn it on and off.
Any power tool that cannot be controlled with the
Trigger is dangerous and must be repaired.
3� Disconnect the plug from the power source
before making any adjustments, 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
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.
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,
taking into account the working conditions
and the work to be performed. Use of the
Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
