4. Do not expose power tools to rain
or wet conditions. Water entering
a power tool will increase the risk of
electric shock.
4. Remove adjusting keys or wrench-
es before turning the power tool
on. A wrench or a key that is left at-
tached to a rotating part of the power
tool may result in personal injury.
5. Do not abuse the Power Cord.
Never use the Power Cord to carry 5. Do not overreach. Keep proper
the tools 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. Dam-
aged Power Cords increase the risk
of electric shock.
footing and balance at all times.
Proper footing and balance enables
better control of the power tool in
unexpected situations.
6. Use safety equipment. always
wear eye protection. Dust mask,
nonskid safety shoes, hard hat, or
hearing protection must be used for
appropriate conditions.
6. When operating a power tool out-
side, 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.
TOOL USE aND CaRE
1. Use clamps (not included) or other
practical ways to secure and sup-
port the workpiece to a stable
platform. Holding the work by hand
or against your body is unstable and
may lead to loss of control.
PERSONaL SaFETY
1. Stay alert. Watch what you are do-
ing, 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 inatten-
tion while operating power tools may
result in serious personal injury.
2. Do not force the tool. Use the cor-
rect tool for your application. The
correct tool will do the job better and
safer at the rate for which it is de-
signed.
3. Do not use the power tool if the
Power Switch does not turn it on
or off. Any tool that cannot be con-
trolled with the Power Switch is dan-
gerous and must be replaced.
2. 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.
4. 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 ac-
cidentally.
3. avoid accidental starting. Be sure
the Power Switch is off before
plugging in. Carrying power tools
with your finger on the Power Switch,
or plugging in power tools with the
Power Switch on, invites accidents.

5. Store idle tools out of reach of chil-
dren and other untrained persons.
Tools are dangerous in the hands of
untrained users.
SPECIFIC SaFETY RULES
1. Wear aNSI-approved safety impact
eye goggles, hearing protection,
and a dust mask or respirator
6. Maintain tools with care. Keep cut-
ting tools sharp and clean. Prop-
erly maintained tools with a sharp
cutting edge are less likely to bind
and are easier to control. Do not use
a damaged tool. Tag damaged tools
“Do not use” until repaired.
when operating this product.
2. The Housing contains a high speed
Impeller that can amputate fingers,
grab loose clothing and long hair,
and propel sawdust at high velocities.
NEVER operate this product without
the all guards and screens in place
and working properly.
7. Check for misalignment or binding
of moving parts, breakage of parts,
and any other condition that may
affect the tool’s operation. If dam-
aged, have the tool serviced before
using. Many accidents are caused
by poorly maintained tools.
3. If using this product to help keep
airborne sawdust within acceptable
limits, you must regularly monitor air-
borne sawdust and maintain the Tool
to avoid exceeding dust limits. Each
application is unique, and your main-
tenance schedule must be tailored to
your specific use.
8. Use only accessories that are
recommended by the manufac-
turer for your model. Accessories
that may be suitable for one tool may
become hazardous when used on
another tool.
4. Industrial applications must follow
OSHA requirements.
5. Use the right tool or attachment
for the right job. Do not attempt to
force a small tool or attachment to
do the work of a larger industrial tool.
There are certain applications for
which this product was designed. It
will do the job better and more safely
at the rate for which it was intended.
Do not modify this product, and do
not use this product for a purpose for
which it was not intended.
SERVICE
1. Tool service must be performed
only by qualified repair personnel.
Service or maintenance performed by
unqualified personnel could result in
a risk of injury.
2. When servicing a tool, use only
identical replacement parts. Fol-
low instructions in the “Inspec-
tion, Maintenance, And Cleaning”
section of this manual. Use of
unauthorized parts or failure to follow
maintenance instructions may create
a risk of electric shock or injury.
6. Turn off the Tool and unplug the
Power Cord Plug from its electrical
outlet before changing accessories
or performing inspection, mainte-
nance, or cleaning procedures.

1. Tools marked with “Grounding Re-
quired” have a three wire cord and
three prong grounding plug. The
plug must be connected to a properly
grounded outlet. If the tool should
electrically malfunction or break
down, grounding provides a low
resistance path to carry electricity
away from the user, reducing the risk
of electric shock. (See 3-Prong Plug
and Outlet.)

3. The tool must be plugged into an
appropriate outlet, properly installed
and grounded in accordance with all
codes and ordinances. The plug and
outlet should look like those in the
preceding illustration. (See 3-Prong
Plug and Outlet.)
7. Make sure the extension cord is prop-
erly wired and in good electrical con-
dition. Always replace a damaged
extension cord or have it repaired by
a qualified electrician before using it.
8. Protect the extension cords from
sharp objects, excessive heat, and
damp or wet areas.
Extension Cords
RECOMMENDED MINIMUM WIRE
1. Grounded tools require a three wire
extension cord. Double Insulated
tools can use either a two or three
wire extension cord.

2. As the distance from the supply outlet
increases, you must use a heavier
gauge extension cord. Using exten-
sion cords with inadequately sized
wire causes a serious drop in voltage,
resulting in loss of power and pos-
sible tool damage.
