WARNING
• The operation of any power tool can result in foreign objects being thrown into your eyes,
which can result in severe eye damage. Before beginning power-tool operation, always wear
safety goggles or safety glasses with side shields and a full-face shield, when needed. We
recommend using a wide vision safety mask over eyeglasses or standard safety glasses
with shields. Always use eye protection marked to comply with ANSI Z87.1.
• Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contains chemicals known to the state of California to cause cancer, birth defects,
or other reproductive harm. Some examples of these chemicals are:
– Lead from lead-based paints
– Crystalline silica from bricks, cement, and other masonry products
– Arsenic and chromium from chemically-treated lumber
• Your risk from these exposures varies, depending upon how often you do this type of work.
To reduce your exposure to these chemicals:
– Work in a well-ventilated area.
– Work with approved safety equipment, such as dust masks that are specially designed to
lter out microscopic particles.
– Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and
other construction activities. Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth or eyes or to lie on the skin may promote
absorption of harmful chemicals.

General Power Tool Safety Warnings
WARNING
• Read all safety warnings, instructions, illustrations and specications 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
• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, 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
• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use
any adaptor plugs with earthed (grounded) power tools. Unmodied plugs and matching

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 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 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 that 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 faction 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 off. 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 pack,
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

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 affect 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 different from those intended could result in
a hazardous situation.
