CALIFORNIA PROPOSITION 65
WAR.I.Gl
Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contains 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, cement and other masonry products, and
®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
filter out microscopic particles. Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or
lay on the skin may promote absorption of harmful chemicals.

,A WARNING 1
To avoid electrical hazards, fire hazards or damage to the tool, use proper
circuit protection. This tool is wired at the factory for 110=120 Volt operation.
It must be connected to a 110=120 Volt /15 Ampere time delay fuse or circuit
breaker. To avoid shock or fire, replace power cord immediately if it is worn,
cut or damaged in any way. Before using your tool, it is critical that you read
and understand these safety rules. Failure to follow these rules could result
in serious injury to you or damage to the tool.

GENERAL SAFETY iNSTRUCTiONS
BEFORE USING THiS POWER TOOL
,
Safety is a combination of common
sense, staying alert and knowing how
to use your power tool. 8.
[,A WARNING1
To avoid mistakes that could cause
serious injury, do not plug the tool in 9.
until you have read and understood
the following.
1. _ READ and become familiar
with the entire Operator's
Manual. LEARN the tool's
application, limitations and possible
hazards.
2. KEEP GUARDS iN PLACE and in
working order.
3. REMOVE ADJUSTING KEYS
AND WRENCHES. Form the habit
of checking to see that keys and
adjusting wrenches are removed
from the tool before turning ON.
4. KEEP WORK AREA CLEAN.
Cluttered areas and benches invite
accidents.
10.
MAKE WORKSHOP CHILD
PROOF with padlocks, master
switches or by removing starter
keys.
DO NOT FORCE THE TOOL. It will
do the job better and safer at the
rate for which it was designed.
USE THE RIGHT TOOL. Do not
force the tool or an attachment
to do a job for which it was not
designed.
USE PROPER EXTENSION
CORDS. Make sure your extension
cord is in good condition. When
using an extension cord, be sure to
use the one heavy enough to carry
the current that the product will
draw. An undersized cord will result
in a drop in line voltage and in
loss of power which will cause the
tool overheat. The table on page
11 shows the proper wire gauge
size usage to each extension cord
length and ampere rating. If in
doubt, use the next heavier gauge.
The smaller the gauge number, the
heavier the cord.
5. DO NOT USE iN DANGEROUS
ENVIRONMENTS. Do not use
power tools in damp locations, or
expose them to rain or snow. Keep
work area well lit.
6. KEEP CHILDREN AWAY. All visitors
and bystanders should be kept a
safe distance from work area.
11.WEAR PROPER APPAREL. Do
not wear loose clothing, gloves,
neckties, rings, bracelets or other
jewelry which may get caught in
moving parts. Nonslip footwear is
recommended. Wear protective
hair covering to contain long hair.

12. _ ALWAYS WEAR EYE 17.
%) PROTECTION, Any power
tool can throw foreign
objects into the eyes and could
cause permanent eye damage.
ALWAYS wear Safety Goggles (not
glasses) that comply with ANSi

you when they break.
13. _ WEAR AFACE MASK
OR DUST MASK. Sawing
operation produces dust.
14. SECURE WORK. Use
clamps or a vice to hold
work when practical. It is
safer than using your hand and
it frees both hands to operate
the tool,
15. DISCONNECT TOOLS FROM
POWER SOURCE before servicing,
and when changing accessories
such as blades, bits and cutters.
16. REDUCE THE RISK OF
UNINTENTIONAL STARTING,
Make sure switch is in the OFF
position before plugging the tool in.
20.
21.
USE RECOMMENDED
ACCESSORIES. Consult
this Operator's Manual for
recommended accessories.
The use of improper accessories
may cause risk of injury to yourself
or others.
NEVER STAND ON THE TOOL,
Serious injury could occur if the
tool is tipped or if the cutting tool is
unintentionally contacted.
CHECK FOR 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 should
be properly repaired or replaced.
NEVER LEAVE THE TOOL
RUNNING UNATTENDED. TURN
THE POWER "OFF". Do not walk
away from a running tool until the
blade comes to a complete stop
and the tool is unplugged from the
power source.
DO NOT OVERREACH. Keep
proper footing and balance at all
times. NEVER reach across the
path of the cutting blade while tool
is in operation.

POWER SUPPLY AND MOTOR
SPECiFiCATiONS
The AC motor used in this saw is
a universal, nonreversible type.
See "MOTOR" in the "PRODUCT
SPECIFICATIONS" section on page 3.
WARNINGl
To avoid electrical hazards, fire
hazards, or damage to the tool, use
proper circuit protection. Your saw
is wired at the factory for 120 V
operation. Connect to a 120 V,
15 A circuit and use a 15 A time
delay fuse or circuit breaker, To
avoid shock or fire, if power cord is
worn or cut, or damaged in any way,
have it replaced immediately.
ELECTRICAL REQUIREMENTS =
DOUBLE INSULATEDr_
The power tool is double insulated to
provide a double thickness of insulation
between you and tool's electrical
system. All exposed metal parts are
isolated from the internal metal motor
components with protecting insulation.
Replacement parts - When servicing
use only identical replacement parts.
Polarized plugs - This saw has a plug
that looks like the one shown below:
To reduce the risk of electrical shock,
this saw has a polarized plug (one
blade is 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 the proper outlet. Do not change
the plug in any way.
WARNING}
Double insulation does not take the
place of normal safety precautions
when operating this tool.
To avoid electrocution:
1. Use only identical replacement
parts when servicing a tool with
double insulation. Servicing
should be performed by a
qualified technician.
2. Do not use power tools in wet or
damp locations or expose them
to rain or snow.
MOTOR SAFETY PROTECTION
IMPORTANT:
To avoid motor damage, the motor
should be blown out or vacuumed
frequently to keep sawdust from
interfering with the motor ventilation.
1. CONNECT this sawto a 120 V, 15A
circuit with a 15 A time-delay fuse or
circuit breaker. Using the wrong size
fuse can damage the motor.
2. If the motor won't start, release the
trigger switch immediately. UNPLUG
THE SAW. Check the saw blade to
make sure it turns freely. If the blade
is free, try to start the saw again. If
the motor still does not start, refer to
the TROUBLESHOOTING GUIDE.
