periods of operation of the tool, or if the operation is noisy.
!
GENERAL SAFETY WARNINGS
WARNING: Before using this tool or any of its accessories, read this
manual and follow all Safety Rules and Operating Instructions. The important
precautions, safeguards and instructions appearing in this manual are not
meant to cover all possible situations. It must be understood that common
sense and caution are factors which cannot be built into the product.
!

ELECTRICAL SAFETY
WARNING: To avoid electrical hazards, fire hazards or damage to the
tool, use proper circuit protection.
This tool is wired at the factory for 120 V AC operation. It must be
connected to a 120 V AC, 15 A circuit that is protected by a time-delayed
fuse or circuit breaker. To avoid shock or fire, replace power cord
immediately if it is worn, cut or damaged in any way.
GENERAL SAFETY WARNINGS
WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
WARNING: Dust that is created by power sanding, sawing, grinding,
drilling, and other construction activities may contain chemicals that are
known to cause cancer, birth defects, or other genetic abnormalities. These
chemicals include:
Lead from lead-based paints
Crystalline silica from bricks, cement, and other masonry products
Arsenic and chromium from chemically treated lumber
The level of risk from exposure to these chemicals varies, according to how
often this type of work is performed. In order to reduce exposure to these
chemicals, work in a well-ventilated area, and use approved safety
equipment, such as a dust mask that is specifically designed to filter out
microscopic particles.
!

GENERAL SAFETY RULES
WARNING: Read and understand
all instructions. Failure to follow all
instructions listed below may result in
electric shock, fire and/or serious personal
injury.
WORK AREA
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in potentially
explosive environments, such as in the
presence of flammable liquids, gas or dust.
Power tools create sparks that may ignite
dust or fumes.
Keep bystanders, children and visitors
away while operating the tool. Distractions
can cause the operator to lose control.
ELECTRICAL SAFETY
Double insulated tools are equipped with a
polarized plug (one blade is wider than the
other). This plug will only fit into a
polarized plug one way.
If the plug does not fit into the outlet
properly, reverse the plug. If it still does not
fit, contact a qualified electrician to install a
polarized outlet. Do not alter the plug in
any way. Double insulation eliminates the
need for the three-pronged grounded
power cord and grounded power supply
system.
Avoid contact between the operator's body
and grounded surfaces such as pipes,
radiators, ranges, and refrigerators. There
is an increased risk of electric shock if the
operator's body is grounded.
Do not expose power tools to rain or wet
conditions. Water entering the power tool
will increase the risk of electric shock.
Do not abuse the cord. Do not use the
power cord to carry the tool or to pull the
plug out of the outlet. Keep the power cord
away from heat, oil, sharp edges, and
moving parts. Replace a damaged power
cord immediately. A damaged power cord
increases the risk of electric shock.
When operating a power tool outdoors,
use an outdoor-rated extension cord type
“W-A” or “W”. These cords are rated for
outdoor use and they reduce the risk of
electric shock.
PERSONAL SAFETY
Stay alert, be aware of the surroundings,
and use common sense when operating a
power tool. Do not use a power tool while
tired or under the influence of drugs,
alcohol, or medication. A moment of
inattention while operating a power tool
may result in serious personal injury.
Dress properly. Do not wear loose clothing
or jewellery.
Contain long hair. Keep hair, clothing, and
gloves away from moving parts. Loose
clothing, jewellery, or long hair can get
caught in moving parts.
!
POWER TOOL SAFETY

6
PERSONAL SAFETY –cont’d
Avoid accidental start-ups. Verify that the
switch is in the OFF position before
plugging in the tool. Carrying a power tool
with a finger on the switch or plugging in a
tool that has the switch in the ON position
invites accidents.
Remove adjusting keys and wrenches
before turning the tool ON. A wrench or
key that is left attached to a rotating part of
the tool may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. Proper footing and
balance allows the operator to maintain
better control of the tool in unexpected
situations.
Use safety equipment. Always wear eye
protection.
Use a dust mask, non-skid safety shoes, a
hardhat, or hearing protection when
appropriate.
USE AND CARE OF POWER TOOLS
Use clamps or another practical means to
secure and support the workpiece to a
stable platform. Holding the work in a hand
or against the body is not stable, and may
lead to loss of control.
Do not force the tool. Use the correct tool
for the application. The correct tool will do
the job better and safer when used at the
rate that it was designed to work at.
Do not use a power tool if it cannot be
turned ON or OFF using the power switch.
A tool that cannot be controlled using the
switch is dangerous, and must be repaired.
Disconnect the plug from the outlet before
making any adjustments, changing
accessories, or storing the tool. Such
preventive safety measures reduce the risk
of accidental start-ups.
When power tools are not in use, store
them out of the reach of children or
untrained persons. Tools are dangerous in
the hands of untrained users.
Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained
cutting tools with sharp cutting edges are
less likely to bind, and are easier to
control.
Inspect the tool for misalignment or binding
of moving parts, broken parts, and any
other condition that may affect the
operation of the tool. If it is damaged, have
the tool serviced before using it. Many
accidents are caused by poorly maintained
tools.
Use only accessories that are
recommended by the manufacturer for this
model. Accessories that are suitable for
one tool may become hazardous when
used with another tool.
SERVICE
Tools servicing must be performed by
qualified personnel. Service or
maintenance performed by non-qualified
personnel could result in a risk of injury.
When servicing a tool, use only identical
replacement parts. Follow the instructions
in the Maintenance section of this Manual.
The use of unauthorized parts or failure to
follow the instructions in the Maintenance
section of this Manual may create a risk of
electric shock or injury.
POWER TOOL SAFETY

7
WARNING: Know your multi-
crafter. Do not plug the tool into the
power source until you have read and
understand this Instruction Manual.
Learn the tool’s applications and
limitations, as well as the specific
potential hazards related to this tool.
Following this rule will reduce the risk of
electric shock, fire, or serious injury.
Always wear eye protection.
Any power tool can throw
foreign objects into your eyes
and cause permanent eye
damage. ALWAYS wear safety goggles
(not glasses) that comply with ANSI safety
standard Z87.1. Everyday glasses have
only impact resistant lenses. They ARE
NOT safety glasses.
WARNING: Glasses or goggles
not in compliance with ANSI Z87.1
could cause serious injury when they
break.
Always keep hands out of the path of the
saw blade. Avoid awkward hand positions
where a sudden slip could cause your
hand to move into the path of the saw
blade.
Secure workpiece. Use clamps or a vice to
hold the workpiece. It is safer than using
your hand and it frees both hands to
operate the tool.
Make sure there are no nails or foreign
objects in the part of the workpiece to be
cut or sanded.
To avoid injury from accidental starting,
always remove the plug from the power
source before installing or removing an
accessory.
Never use dull blades in the tool. They will
cut slower, leave rough cuts and break
easily due to added pressure and
excessive heat. They will also overload the
motor and cause premature failure of the
tool.
Never use damaged or bent blades. They
will be brittle and break easily possibly
causing injury to the operator.
Never touch a saw blade immediately after
using the tool. The blade will be extremely
hot and will burn your hand.
Only use accessories designed for use
with this tool.
