Safety Warnings and
precautions
WARNING: When using tool, basic safety precautions should always be followed to reduce the risk
of personal injury and damage to equipment.
such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if
your body is grounded.
7. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
8. Do not abuse the power cord. Never use the
power cord to carry the tool or pull the plug
from an outlet. Keep the power cord away
from heat, oil, sharp edges, or moving parts.
Replace damaged power cords immediately.
Damaged Power Cords increase the risk of electric shock.
Read all instructions before using this
tool!
1. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases, or dust. Power tools create
sparks which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away
while operating a power tool. Distractions can
cause you to lose control. Protect others in the
work area from debris such as chips and sparks.
Provide barriers or shields as needed.
4. 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 adapter plugs. check
with a qualied electrician if you are in doubt
whether the outlet is properly grounded. If the
tool should electrically malfunction or break down,
grounding provides a low resistance path to carry
electricity away from the user.
5. Double insulated tools are equipped with a
polarized plug (one blade is wider than the
other). This plug will t in a polarized outlet
only one way. If the plug does not t fully in
the outlet, reverse the plug. If it still does not
t, contact a qualied electrician to install a
polarized outlet. Do not change the plug in any
way. Double insulation eliminates the need for the
three wire grounded power cord and grounded
power supply system.
6. Avoid body contact with grounded surfaces
9. When operating a power tool outside, use an
outdoor extension cord marked “W-A” or “W”.
These extension cords are rated for outdoor use,
and reduce the risk of electric shock.
personal Safety
10. Stay alert. Watch what you are doing, and use
common sense when operating a power tool.
Do not use a power tool while tired or under
the inuence of drugs, alcohol, or medication.
A moment of inattention while operating power
tools may result in serious personal injury.
11. Dress properly. Do not wear loose clothing
or jewelry. contain long hair. Keep your hair,
clothing, and gloves away from moving parts.
Loose clothes, jewelry, or long hair can be caught
in moving parts.
12. Avoid accidental starting. Be sure the power
Switch is off before plugging in. Carrying power
tools with your nger on the Power Switch, or
plugging in power tools with the Power Switch on,
invites accidents.
13. Remove adjusting keys or wrenches before
turning the power tool on. A wrench or a key
that is left attached to a rotating part of the power
tool may result in personal injury.
14. Do not overreach. Keep proper footing and
balance at all times. Proper footing and balance
enables better control of the power tool in unexpected situations.
15. use safety equipment. Always wear eye
protection. Dust mask, nonskid safety shoes,
hard hat, or hearing protection must be used for
appropriate conditions.
16. WARNING! Some dust created by power sanding,
sawing, grinding, drilling, and other construction

activities, contain 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.)
Service
23. tool service must be performed only by quali-
ed repair personnel. Service or maintenance
performed by unqualied personnel could result in
a risk of injury.
24. When servicing a tool, use only identical
replacement parts. Use of unauthorized parts or
failure to follow maintenance instructions may create a risk of electric shock or injury.
Specic Safety Rules
tool use and care
16. use clamps (not included) or other practical
ways to secure and support the work piece
to a stable platform. Holding the work by hand
or against your body is unstable and may lead to
loss of control.
17. Do not force the 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.
18. Do not use the power tool if the power Switch
does not turn it on or off. Any tool that cannot be
controlled with the Power Switch is dangerous and
must be replaced.
19. Disconnect the power cord plug from the
power source before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the risk
of starting the tool accidentally.
20. Store idle tools out of reach of children and
other untrained persons. Tools are dangerous
in the hands of untrained users.
21. Maintain tools with care. Keep cutting tools
maintained and clean. Properly maintained tools
are less likely to bind and are easier to control. Do
not use a damaged tool. Tag damaged tools “Do
not use” until repaired.
22. 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.

cONNEctION:
Check with a qualied electrician
if you are in doubt as to whether
the outlet is properly grounded.
Do not modify the power cord
plug provided with the tool.
Never remove the grounding
prong from the plug. Do not use
the tool if the power cord or plug
is damaged. If damaged, have it
repaired by a service facility
before use. If the plug will not t
the outlet, have a proper outlet
installed by a qualied
electrician.
Double insulated tools may be used in
2.
either of the 120 volt outlets shown in the
preceding illustration. (See Outlets for
2-prong plug.)
Extension cords
Grounded1. tools require a three wire
extension cord. Double Insulated
tools can use either a two or three wire
extension cord.
As the distance from the supply outlet 2.
increases, you must use a heavier gauge
extension cord. Using extension cords
with inadequately sized wire causes a
serious drop in voltage, resulting in loss
of power and possible tool damage.
(See table A.)
The smaller the gauge number of the 3.
wire, the greater the capacity of the cord.
For example, a 14 gauge cord can carry
a higher current than a 16 gauge cord.
(See table A.)
