GENERAL SAFETY RULES USAW2-’
(For All Tools)
WARNING! Read and understand all instructions. Failure
tofollow all instructionslisted below, may result inelectric
shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
1. Keepyour work area cleanand well lit. Cluttered benches and dark areas invite
accidents.
2. Do notoperate power tools in explosiveatmospheres, suchas inthe presence
of flammable 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.
Electrical Safety
4. Double Insulatedtools are equipped with apolarized plug(onebladeis 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 eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. Avoid body contact withgrounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is
grounded.
6. Donotexpose powertoolstorainor wetconditions. Water entering a power
tool
will increase the risk of electric shock.
7. Donotabuse the cord. Never use the cordtocarry the tools or pullthe plug
from an outlet. Keepcordaway from heat, oil, sharp edges or movingparts.
Replace damaged cords immediately. Damaged cords increase the risk
of
electric shock.
8. Whenoperating a powertooloutside, useanoutdoorextension cordmarked
“W-A“ or “W.“ These cords are rated for outdoor use and reduce the risk
of electric shock.
Personal Safety
9. Stay alert, watchwhat youare doing andusecommonsensewhenoperating
a power tool. Do not use tool while tired or under the influence of drugs,
alcohol, or medication. A momentof inattentionwhile operating power tools
may result
in serious personal injury.
IO. Dressproperly. Donotwear looseclothingorjewelry. Contain longhair. Keep
your hair, clothing, andglovesaway frommovingparts. Looseclothes, jewelry
or long hair can be caught
in moving parts.

11. Avoid accidental starting. Be sure switchis off before plugging in. Carrying
tools with your finger on the switch or plugging in tools that have the switch
on invites accidents.
12. Removeadjusting keys or wrenches before turning the tool on. A wrench
or
a key that is left attached to a rotatingpart of the tool may resultinpersonal
injury.
13.
Do notoverreach.Keepproperfootingand balanceat alltimes. Proper footing
and balance enables better control of the tool in unexpected situations.
14. 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
15. Use clamps or other practicalway tosecure and support the workpiece to
a stable platform. Holdingthe work by hand or against your body is unstable
and may lead to
loss of control.
16. Donotforce 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.
17. 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.
18. Disconnectthe plugfrom the powersource before makingany adjustments,
changing accessories, or storing the
tool. Such preventive safety measures
reduce the risk of starting the tool accidentally.
19. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
20. Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintainedtools, with sharp cuttingedges are less likelytobind andare easier
to control.
21. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tools operation.
If damaged, have
the tool serviced before using. Many accidents are caused by poorly
maintained tools.
22. Use only accessories that are recommended by the manufacturerfor your
model. Accessories that may be suitablefor one tool, may become hazardous
when used on another tool.
SERVICE
23. Tool service must be performedonly by qualifiedrepair personnel. Service
or maintenance performed
by unqualified personnel could result in a risk of
injury.
24. When servicing a tool, use only identical replacement parts. Follow
instructions
in the Maintenancesectionof this manual. Use of unauthorized
parts or failuretofollow Maintenance Instructionsmay createarisk of electric
shock or injury.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known
[to the State of Califomia] to
cause cancer, birth defects or other reproductive harm. Some examples of
these chemicals are:
9 Crystalline silicafrom bricksand cement and other masonry products, and
9 Arsenic andchromiumfrom 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 masksthat are specially designed
to filter out microscopic particles.
