GENERAL SAFETY mNSTRUCTMONS
BEFORE USING THE M_TER SAW
Safety is a combination of common sense, staying alert
and knowing how to use your miter saw.
To avoid mistakes that could cause serious injury, do
not plug the tool in until you have read and understood
the following.
t. READ and become familiar with the entire
Operators Manual. LEARN the tool's application,
limitations and possible hazards.
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.
.
DON'T USE IN DANGEROUS ENVIRONMENT.
Don't use power tools in damp locations, or expose
them to rain or snow. Keep work area well lighted.
.
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. DON'T 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 tool or
attachment to do a job for which it was not designed.
1&USE 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 wilt draw. An
undersized cord wilt result in a drop in line voltage
and in loss of power which will cause the toot 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.
!2.ALWAYS WEAR EYE PROTECTION. Any power
toot 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 - resistance 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, lt's safer than using your hand and it
frees both hands to operate tool.
15.DISCONNECT TOOLS before servicing, and when
changing accessories such as blades, bits and
cutters.
1&REDUCE THE RISK OF UNINTENTIONAL
STARTING. Make sure switch is in OFF position
before plugging in.

ELECTRgCAL REQUBREMENTS
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.
To avoid electrical hazards, fire hazards, or
damage to the tool, use proper circuit protection.
Your saw is wired at the factory for 120V ....
operation. Connect to a 120V, 15 Amp circuit and
use a 15 amp. 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.
DOUBLE INSULATED [_
The power tool is double insulated to provide a double
thickness of insulation between you and tool's electrical
system. Aft exposed metal parts are isolated from the
internal metal motor components with protecting
insulation.
Replacement parts-When servicing use only identical
replacement parts.
Pomarized 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. tf 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.
Double insulation does not take the place of normal
safety precautions when operating this tool.
To avoid electrocution:
t. Use only identical replacement parts when servicing a
too! 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.
This toot is intended for indoor use only.
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.
I. CONNECT this saw to a 120V, 15 amp. circuit with a
15 amp. time delay fuse or circuit breaker. Using the
wrong size fuse can damage the motor.
2. IFthe motor won't start, release the trigger switch
immediately. UNPLUG THE SAW. Check the saw
blade to make sure it turns freely. Ifthe 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.
4. FUSES may "blow" or circuit breakers may trip
frequently if:
a. ]MOTOR is overloaded °V 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,
however the voltage at motor terminals must equal
the voltage specified on the nameplate.
c. mMPROPER 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.
GUBDEUNES FOR EXTENSION CORDS
USE 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 cause 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.
Be sure your extension cord ks 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 # 12 wire and should be
protected with a 15 Amp time delay fuse. Before
connecting the toot 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.
