General Safety Instructions
WARNING! Read and understand all instructions. Failure to
follow all instructions listed below, may result in electric shock,
fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
• Keep your work area clean and well lit. Cluttered benches and
dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquids, gases, or dust.
Power tools create sparks which may ignite the dust or fumes.
• Keep bystanders, children, and visitors away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
• Grounded tools must be plugged into an outlet properly
installed and grounded in accordance with all codes and
ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any adaptor plugs. Check
with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically
malfunction or break down, grounding provides a low resistance
path to carry electricity away from the user. Applicable only to
Class I (grounded) tools.
• Double insulated tools are equipped with a polarized plug
(one blade is wider than the other.) This plug will fit in a
polarized outlet only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation
the need for the three wire grounded power cord and grounded
power supply system. Applicable only to Class II (double
insulated) tools.
• 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.
• Don’t expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord to carry the
tools or pull the plug from an outlet. Keep cord away from
heat, oil, sharp edges or moving parts. Replace damaged
cords immediately. Damaged cords increase the risk of electric
shock.
• When operating a power tool outside, use an outdoor
extension cord marked “W-A” or “W.” These cords are rated
for outdoor use and reduce the risk of electric shock. When using
an extension cord, be sure to use one heavy enough to carry the
eliminates

current your product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and overheating.
The following table shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt, use the
next heavier gauge. The smaller the gauge number, the heavier
the cord.

PERSONAL SAFETY
• Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use tool
while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating power
tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing or jewelry.
Contain long hair. Keep your hair, clothing, and gloves
away from moving parts. Loose clothing, jewelry, or long hair
can be caught in moving parts. Air vents often cover moving
parts and should also be avoided.
• Avoid accidental starting. Be sure switch is off before
plugging in. Carrying tools with your finger on the switch or
plugging in tools that have the switch on invites accidents.
Total length of cord in meters (m)
Minimal cross-sectional area of the
cord in meters (mm2 )
• Remove adjusting keys or wrenches before turning the tool
on. A wrench or a 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 enables better control of the
tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust
mask, non-skid safety shoes, hard hat, or hearing protection
must be used for appropriate conditions.
TOOL USE AND CARE
• Use clamps or other practical way to secure and support
the workpiece to a stable platform. Holding the work by
hand or against your body is unstable and may lead to loss of
control.
• Do not force tool. Use the correct tool for your application.
The correct tool will do the job better and safer at the rate for
which it is designed.
• Do not use tool if switch does not turn it on or off. Any tool
that cannot be controlled with the switch is dangerous and must
be repaired.
• Disconnect the plug from the power source before making
any adjustments, changing accessories, or storing the tool.
Such preventative safety measures reduce the risk of starting
the tool accidentally.
• Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
• Maintain tools with care. Keep cutting tools sharp and
clean. Properly maintained tools, with sharp cutting edges are
less likely to bind and are easier to control.
• Check for misalignment or binding of moving parts, breakage
of parts, and any other condition that may affect the tool’s
operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.

• Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool, may become hazardous when used on
another tool.
SERVICE
• Tool service must be performed only by qualified repair
personnel. Service or maintenance performed by unqualified
English
personnel could result in a risk of injury.
• When servicing a tool, use only identical replacement
parts. Follow instructions in the Maintenance section of
this manual. Use of unauthorized parts or failure to follow
maintenance instructions may create a risk of electric shock or
injury.
Additional Specific Safety Instructions
for Jig Saws
• Hold tool by insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden
wiring or its own cord. Contact with a “live” wire will make
exposed metal parts of the tool “live” and shock the operator.
• Allow the motor to come to a complete stop before
withdrawing the blade from the kerf (the slot created by
cutting). A moving blade may impact the workpiece causing a
broken blade, workpiece damage or loss of control and possible
personal injury.
• Keep handles dry, clean, free from oil and grease. This will
enable better control of the tool.
• Keep blades sharp. Dull blades may cause the saw to swerve
or stall under pressure.
• Clean out your tool often, especially after heavy use. Dust
and grit containing metal particles often accumulate on interior
surfaces and could create an electric shock hazard.
• Do not operate this tool for long periods of time. Vibration
caused by the operating action of this tool may cause permanent
injury to fingers, hands, and arms. Use gloves to provide extra
cushion, take frequent rest periods, and limit daily time of use.
WARNING: Always wear eye protection while operating this
power tool.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chemicals
known 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 and other masonry
products, and
• arsenic and chromium from chemically-treated lumber
(CCA).
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 filter 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, eyes, or lay on
the skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust,
which may cause serious and permanent respiratory or other injury.
Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face
and body.
WARNING: ALWAYS USE SAFETY GLASSES. Everyday
eyeglasses are NOT safety glasses. Also use face or dust mask if
cutting operation is dusty. All users and bystanders MUST ALWAYS
wear certified safety equipment:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
