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.
[,_ WARNING]
To avoid mistakes that could cause serious injury,
do not plug the tool in until you have read and
understood the following.
,
2. KEEP GUARDS IN PLACE and in working order.
, 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.
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,
7. MAKE WORKSHOP CHILD PROOF with padlocks,
master switches or by removing starter keys.
8. DO NOT FORCE THE TOOL. It will do the job better
and safer at the rate for which it was designed.
9. USE THE RIGHT TOOL. Do not force the tool or an
attachment to do a job for which it was not designed.
10. USE PROPER EXTENSION CORDS. Make sure
your extension cord is in good condition. When
using an extension cord, be sure to use one heavy
enough to carry the current your product will draw.
An undersized cord will result in a drop in line
voltage and in loss of power which will cause the
tool to overheat. The table on page 5 shows the
correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next
heavier gauge. The smaller the gauge number, the
heavier the cord.
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.
READ and become familiar with the
entire Operator's Manual. LEARN the
tool's application, limitations and possible
hazards.
12._ ALWAYS WEAR EYE 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 Safety standard
Z87.1. Everyday eyeglasses have only impact-
resistant lenses. They ARE NOT safety glasses.
Safety Goggles are available at Sears. NOTE:
Glasses or goggles not in compliance with ANSI
Z87.1 could seriously injure you when they break.
13. WEAR A FACE MASK OR DUST MASK. Sawing
operation produces dust.
14.
SECURE WORK. Use clamps or a vise 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.
17. 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.
18. NEVER STAND ON THE TOOL. Serious injury
could occur if the tool is tipped or if the cutting tool
is unintentionally contacted.
19.
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
20.
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,
21.

changing the workpiece angle or changing the angle
of the blade.
20. NEVER cut metals or masonry products with this
tool. This miter saw is designed for use on wood
and wood-like products.
21. NEVER cut small pieces. If the workpiece being cut
would cause your hand or fingers to be within 8-3/4
in. of the saw blade the workpiece is too small.
22. PROVIDE adequate support to the sides of the saw
table for long work pieces,
23. NEVER use the miter saw in an area with flammable
liquids or gases.
24. NEVER use solvents to clean plastic parts. Solvents
could possibly dissolve or otherwise damage the

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 2.
I_ WARNING]
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.
5
ELECTRICALREQUIREMENTS- cont'd
DOUBLE INSULATED []
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.
4. FUSES may "blow" or circuit breakers may trip
frequently if:
a. MOTOR is overloaded - overloading can occur
if you feed too rapidly or make too many start/
stops in a short time.
b. LINE VOLTAGE is more than 10% above or
below the nameplate voltage rating. For heavy
loads, the voltage at motor terminals must equal
the voltage specified on the nameplate.
c. IMPROPER or dull saw blades are used.
5. Most motor troubles may be traced to loose or
incorrect connections, overload, low voltage or
inadequate power supply wiring. Always check the
connections, the load and supply circuit if the motor
doesn't run well. Check minimum gauge for the
length of cord you are using on the chart below.
GUIDELINES FOR EXTENSION CORDS
Use a proper extension cord. Make sure your extension
cord is in good condition. When using an extension
cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord will
cause a drop in line voltage, resulting in loss of power
and overheating. The table below shows the correct size
to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
[,_ 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 saw to a 120 V circuit. This circuit
must not be less than a #12 wire with a 20 A time
lag fuse or a #14 wire with a 15 A time lag fuse.
NOTE: When using an extension cord on a circuit
with a #14 wire, the extension cord must not exceed
25 feet in length.
2. If the motor will not 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.
3. If the tool suddenly stalls while cutting wood, release
the trigger switch, unplug the tool and free the blade
from the wood. The saw may now be started and
the cut finished.
Be sure your extension cord is properly wired and
in good condition. Always replace a damaged extension
cord or have it repaired by a qualified person before
using it. Protect your extension cords from sharp
objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This
circuit must not be less than a #12 wire with a 20 A
time lag fuse or a #14 wire with a 15 A time lag fuse.
NOTE: When using an extension cord on a circuit with
a #14 wire, the extension cord must not exceed 25 feet
in length. Before connecting the tool to the power line,
make sure the switch is in the OFF position and the
electric current is rated the same as the current stamped
on the motor nameplate, running at a lower voltage will
damage the motor.
