General Power Tool Safety Warnings
WARNING Read all safety warnings
and instructions. Failure to follow the
warnings and instructions 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 batteryoperated (cordless) power tool.
1. Work area safety
a. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b. 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.
c. Keep children and bystanders
away while operating a
power tool. Distractions can
cause you to lose control.
2. Electrical safety
a. Power tool plugs must match the
outlet. Never modify the plug in
any way. Do not use any adapter
plugs with grounded power tools.
Unmodied plugs and matching outlets
will reduce risk of electric shock..
b. Do not expose power tools to
rain or wet conditions. Water

entering a power tool will increase
the risk of electric shock.
c. 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.
d. 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.
e. 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.
d. Do not overreach. Keep proper
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
e. 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.
f. 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 specic hazards in the work area.
4. Power tool use and care
3. Personal safety
a. 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 inuence of drugs,
alcohol or medication. A moment of
inattention while operating power tools
may result in serious personal injury.
b. Use personal protective equipment.
Always wear eye protection. Safety
equipment such as dust mask, non-
skid safety shoes, hard hat, or hearing
protection used for appropriate
conditions will reduce personal injuries.
c. 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.
a. 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.
b. 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.
c. 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 preventive safety
measures reduce the risk of starting
the power tool accidentally.
d. 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.

e. 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.
f. Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely
to bind and are easier to control.
5. Unplug before inspecting,
removing or installing chisel,
or performing any service.
6. Pull on chisel after installation
and before use; chisel may move
but MUST NOT slide out.
7. Do not operate this tool if you have
back, neck, or wrist injuries, or other
conditions that will be aggravated
by the severe jerking forces that this
tool exerts upon the operator.
g. 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.
5. Service
a. Have your power tool serviced by
a qualied repair person using
only identical replacement parts.
This will ensure that the safety of
the power tool is maintained.

pacemakers should:
• Avoid operating alone.
• Properly maintain and inspect to avoid
electrical shock.
• Any power cord must be properly
grounded. Ground Fault Circuit
Interrupter (GFCI) should also
be implemented – it prevents
sustained electrical shock.
15. WARNING: 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 and
cement or other masonry products
• Arsenic and chromium from chemically
treated lumber
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to
these chemicals: work in a well ventilated
area, and work with approved safety
equipment, such as those dust masks
that are specially designed to lter out
microscopic particles. (California Health
& Safety Code § 25249.5, et seq.)
16. WARNING: Handling the cord on this
product will expose you to lead, a
chemical known to the State of California

instructions discussed in this instruction
manual cannot cover all possible
conditions and situations that may
occur. It must be understood by the
operator that common sense and
caution are factors which cannot
be built into this product, but must
be supplied by the operator.
Vibration Safety
This tool vibrates during use. Repeated
or long-term exposure to vibration
may cause temporary or permanent
physical injury, particularly to the
hands, arms and shoulders. To reduce
the risk of vibration-related injury:
1. Anyone using vibrating tools regularly
or for an extended period should rst
be examined by a doctor and then
have regular medical check-ups to
ensure medical problems are not
being caused or worsened from use.
Pregnant women or people who have
impaired blood circulation to the hand,
past hand injuries, nervous system
disorders, diabetes, or Raynaud’s
Disease should not use this tool. If
you feel any symptoms related to
vibration (such as tingling, numbness,
and white or blue ngers), seek
medical advice as soon as possible.
2. Do not smoke during use. Nicotine
reduces the blood supply to the
hands and ngers, increasing the
risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration-free periods
each day of work.
6. Let the tool do the work.
7. To reduce vibration, maintain
the tool as explained in this
manual. If any abnormal vibration
occurs, stop use immediately.
