n KEEP CHILDREN AND VISITORS AWAY. All visitors
should wear safety glasses and be kept a safe
distance from work area. Do not let visitors contact
tool or extension cord while operating.
n MAKE WORKSHOP CHILDPROOF with padlocks,
master switches, or by removing starter keys.
n DON’T FORCE THE TOOL. It will do the job better and
safer at the feed rate for which it was designed.
n USE THE RIGHT TOOL. Do not force the tool or at-
tachment to do a job for which it was not designed.
n USE THE PROPER EXTENSION CORD. Make sure
the extension cord is in good condition. Use only a
cord heavy enough to carry the current the product will
draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. A wire
gauge size (A.W.G.) of at least 16 is recommended for
an extension cord 25 feet or less in length. If in doubt,
use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
n DRESS PROPERLY. Do not wear loose clothing, neck-
ties, or jewelry that can get caught and draw you into
moving parts. Rubber gloves and nonskid footwear
are recommended when working outdoors. Also wear
protective hair covering to contain long hair.
n ALWAYS WEAR SAFETY GLASSES WITH SIDE
SHIELDS. Everyday eyeglasses have only impact-
resistant lenses, they are NOT safety glasses.
n SECURE WORK. Use clamps or a vise to hold work
when practical, it is safer than using your hand and
frees both hands to operate the tool.
n DO NOT OVERREACH. Keep proper footing and
balance at all times.
n MAINTAIN TOOLS WITH CARE. Keep tools sharp
and clean for better and safer performance. Follow
instructions for lubricating and changing accessories.
n DISCONNECT TOOLS. When not in use, before
servicing, or when changing attachments, blades, bits,
cutters, etc., all tools should be disconnected from
power source.
n AVOID ACCIDENTAL STARTING. Be sure switch is off
when plugging in any tool.
n USE RECOMMENDED ACCESSORIES. Consult the
operator’s manual for recommended accessories. The
use of improper accessories may result in injury.
n NEVER STAND ON TOOL. Serious injury could occur
if the tool is tipped.
n CHECK DAMAGED PARTS. Before further use of
the tool, a guard or other part that is damaged should
be carefully checked to determine that it will operate
properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts,
breakage of parts, mounting and any other conditions
that may affect its operation. A guard or other part that
is damaged must be properly repaired or replaced by
an authorized service center to avoid risk of personal
injury.
n USE THE RIGHT DIRECTION OF FEED. Feed work
into a blade, cutter, or sanding spindle against the
direction or rotation of the blade, cutter, or sanding
spindle only.
n NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN THE POWER OFF. Don’t leave tool until it
comes to a complete stop.
n PROTECT YOUR LUNGS. Wear a face or dust mask if
the cutting operation is dusty.
n PROTECT YOUR HEARING. Wear hearing protection
during extended periods of operation.
n DO NOT ABUSE CORD. Never carry tool by the cord
or yank it to disconnect from receptacle. Keep cord
from heat, oil, and sharp edges.
n USE OUTDOOR EXTENSION CORDS. When tool
is used outdoors, use only extension cords with
approved ground connection that are intended for use
outdoors and so marked.
n KEEP BLADES CLEAN, SHARP, AND WITH
SUFFICIENT SET. Sharp blades minimize stalling

Normal sparking of the motor could ignite fumes.
n INSPECT TOOL CORDS PERIODICALLY. If damaged,
have repaired by a qualified service technician at
an authorized service facility. The conductor with
insulation having an outer surface that is green with
or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Repair
or replace a damaged or worn cord immediately. Stay
constantly aware of cord location and keep it well away
from the rotating blade.
n INSPECT EXTENSION CORDS PERIODICALLY and
replace if damaged.
n KEEP TOOL DRY, CLEAN, AND FREE FROM OIL
AND GREASE. Always use a clean cloth when clean-
ing. Never use brake fluids, gasoline, petroleum-based
products, or any solvents to clean tool.
n STAY ALERT AND EXERCISE CONTROL. Watch
what you are doing and use common sense. Do not
operate tool when you are tired. Do not rush.
n DO NOT USE TOOL IF SWITCH DOES NOT TURN IT
ON AND OFF. Have defective switches replaced by an
authorized service center.
n USE ONLY CORRECT BLADES. Use the right blade
size, style, and cutting speed for the material and the
type of cut. Blade teeth should point down toward the
table.
n BEFORE MAKING A CUT, BE SURE ALL ADJUST-
MENTS ARE SECURE.
n BE SURE BLADE PATH IS FREE OF NAILS. Inspect
for and remove all nails from lumber before cutting.
n NEVER TOUCH BLADE or other moving parts during
use.
n NEVER START A TOOL WHEN ANY ROTATING COM-
PONENT IS IN CONTACT WITH THE WORKPIECE.

ELECTRICAL
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept the
tool’s plug. When using a power tool at a considerable
distance from the power source, use an extension cord
heavy enough to carry the current that the tool will draw.
An undersized extension cord will cause a drop in line
voltage, resulting in a loss of power and causing the motor
to overheat. Use the chart provided below to determine
the minimum wire size required in an extension cord. Only
round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.

**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
When working with the tool outdoors, use an extension
cord that is designed for outside use. This is indicated by
the letters “WA” on the cord’s jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
WARNING: Keep the extension cord clear of the
working area. Position the cord so that it will not get
caught on lumber, tools or other obstructions while
you are working with a power tool. Failure to do so
can result in serious personal injury.
WARNING: Check extension cords before each
use. If damaged replace immediately. Never use tool
with a damaged cord since touching the damaged
area could cause electrical shock resulting in serious
injury.
ELECTRICAL CONNECTION
This tool is powered by a precision built electric motor.
It should be connected to a power supply that is 120
volts, 60 Hz, AC only (normal household current). Do
not operate this tool on direct current (DC). A substantial
voltage drop will cause a loss of power and the motor will
overheat. If the saw does not operate when plugged into
an outlet, double check the power supply.
SPEED AND WIRING
The no-load speed of this tool is approximately 1,600
spm. This speed is not constant and decreases under
a load or with lower voltage. For voltage, the wiring in a
shop is as important as the motor’s horsepower rating. A
line intended only for lights cannot properly carry a power
tool motor. Wire that is heavy enough for a short distance
will be too light for a greater distance. A line that can
support one power tool may not be able to support two
or three tools.
GROUNDING INSTRUCTIONS
In the event of a malfunc
provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped with
an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a
matching outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor
with insulation having an outer surface that is green with or
without yellow stripes is the equipment-grounding
conductor. If repair or replacement of the electric cord or
plug is necessary, do not connect the equipmentgrounding conductor to a live terminal.
Check with a qualified electrician or service personnel if
the grounding instructions are not completely understood,
or if in doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
This tool is intended for use on a circuit that has an outlet
like the one shown in figure 1. It also has a grounding pin
like the one shown.
