Failure
tofollow all instructions listed below, may result
in
electric
shock,
fire and/or serious personal injury.
SAVE
THESE
INSTRUCTIONS
Work Area
1.
Keep your work area cleanand well
lit.
Clutteredbenches and dark areas invite
accidents.
2.
Donotoperate powertools
in
explosiveatmospheres, such as
in
the 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.
DoubleInsulatedtools are equipped
with
a polarized plug (oneblade iswider
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
El
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.
Do
notabuse the cord. Never use the cordtocarry thetoolsor pullthe plug
from anoutlet. Keepcordaway fromheat, oil, sharp edges or movingparts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
8.
When operating apower tooloutside, usean outdoor extension cord marked
"W-A'
or "W." These cords are rated for outdoor use and reduce the risk
of
electric shock.

is
off
before
plugging
in.
Carrying
tools withyour finger onthe switchor plugging
in
tools that havetheswitch
on invites accidents.
12.
Remove adjusting keys or wrenches before turning the tool on. A wrench
or a key thatisleftattachedtoa rotatingpartofthetool may result
in
personal
injury.
13.
Do
notoverreach. Keepproper footingand balance atalltimes. Properfooting
and balance enables better control of the tool
in
unexpected situations.
14.

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 practical way to secure and support the workpiece
to
a stable platform. Holdingthe work by handor against your body is unstable
and may lead to loss of control.
16.
Do
notforce tool. Use the correct toolfor 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 plugfromthe power source before making any 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
maintained tools,
with
sharp cutting edges are less likely to
bind
and are easier
to control.
21.
Check for misalignment or binding of moving parts, breakageof 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 manufacturer for your
model. Accessories that maybe suitablefor one tool, may becomehazardous
when used on another tool.
