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
• 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 dust masks that are
specially designed to filter out microscopic particles.

GENERAL SAFETY INSTRUCTIONS
BEFORE USING THE MITER 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.
.
.
3.
.
READ and become familiar with the entire Operators
Manual. LEARN the tool's application, limitations and
possible hazards.
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.
KEEP WORK AREA CLEAN. Cluttered areas and
benches invite accidents.
5. DON'T USE IN DANGEROUS ENVIRONMENTS.
Don't use power tools in damp locations, or expose
them to rain or snow. Keep work area well lighted.
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. 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 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.
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-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. It's safer than using your hand and it
frees both hands to operate tool.
15.DISCONNECT TOOLS before the 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
Operators 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.
20.NEVER LEAVE THE TOOL RUNNING UNATTENED.
TURN THE POWER "OFF". Don't walk away from a
running tool until the blade comes to a complete stop
& unplug the unit.
21. DON'T OVERREACH. Keep proper footing and
balance at all times.
22. MAINTAIN TOOLS WITH CARE. Keep tools sharp
and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.
23.WARNING: Dust generated from certain materials
can be hazardous to your health. Always operate saw
in well-ventilated area and provide for proper dust
removal.
. USE ONLY CROSS-CUTTING SAW BLADES. When
using carbide tipped blades, make sure they have a
negative hook angle. IMPORTANT: DO NOT USE
THIN KERF BLADES- they can deflect and contact
guard and can cause possible injury to the operator.
2. DO NOT operate the miter saw until it is completely
assembled and installed according to these
instructions.
.
.
.
IF YOU ARE NOT thoroughly familiar with the
operation of miter saws, seek guidance from your
supervisor, instructor, or other qualified person.
ALWAYS hold the work firmly against the fence and
table. DO NOT perform any operation free hand (use
clamp wherever possible).
KEEP HANDS out of the path of the saw blade. If the
workpiece you are cutting would cause your hands to
be within 8-1/2" inches of the saw blade, the
workpiece should be clamped in place before making
the cut.
6. BE SURE the blade is sharp, runs freely, and is free
of vibration.
7. ALLOW the motor to come up to full speed before
starting a cut.
8. KEEP THE MOTOR AIR SLOTS CLEAN and free of
chips or dust.
9. ALWAYS MAKE SURE all handles are tight before
cutting, even if the table is positioned in one of the
positive stops.
10.BE SURE both the blade and the collar are clean and
the arbor bolt is tightened securely.
11. USE only blade collars specified for your saw.
12. NEVER use blades larger or smaller in diameter
than 12-inches.
13. NEVER apply lubricants to the blade when it is
running.
14. ALWAYS check the blade for cracks or damage
before operation. Replace a cracked or damaged
blade immediately.
15. NEVER use blades recommended for operation at
less than 4000 RPM.
16. USE the blade guards at all times.
17.ALWAYS keep the blade guards in place.
18.NEVER reach around the saw blade.
19.MAKE SURE the blade is not contacting the
workpiece before the switch is turned ON.
20. IMPORTANT: After completing the cut, release the
power switch and wait for the blade to stop before
returning the saw to the raised position.
21.MAKE SURE the blade has come to a complete stop
before removing or securing the workpiece, changing
the workpiece angle, or changing the angle of the
blade.
22. NEVER cut metals or masonry products with this tool.
This miter saw is designed for use on wood and
wood-like products.
23.NEVER cut small pieces. If the workpiece being cut
would cause your hand or fingers to be within 8-1/2"
inches of the saw blade the workpiece is too small.
24.PROVIDE adequate support to the sides of the saw
table for long work pieces.
25.NEVER use the miter saw in an area with flammable
liquids or gases.
26.NEVER use solvents to clean plastic parts. Solvents
could possibly dissolve or otherwise damage the
material.
27.SHUT OFF the power before servicing or adjusting
the tool.
28. DISCONNECT the saw from the power source and
clean the machine when finished using.
29.MAKE SURE the work area is clean before leaving
the machine.
30.SHOULD any part of your miter saw be missing,
damaged, or fail in any way, or any electrical
component fail to perform properly, shut off the switch
and remove the plug from the power supply outlet.
Replace missing, damaged, or failed parts before
resuming operation.
ELECTRICAL REQUIREMENTS
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.
DOUBLEINSULATED[]

.....
,J
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.
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.
This tool is intended for indoor use only.
MOTOR SAFETY PROTECTION
IM PORTANT:
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 120V, 15 amp. circuit with a 15
amp. 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"
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 - 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 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 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 # 12 wire and should be
protected with a 15 Amp time delay fuse. 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.

ACCESSORIES
Visit your Sears Hardware Department or see the Sears
Power and Hand Tool Catalog to purchase recommended
accessories for this power tool.
To avoid the risk of personal injury, do not modify this
power tool or use accessories not recommended by Sears.
Read warnings and conditions on your CARBIDE TIPPED
SAW BLADE. Do not operate the saw without the proper
saw blade guard in place. Carbide is a very hard but brittle
material. Care should be taken while mounting, using, and
storing carbide tipped blades to prevent accidental
damage. Slight shocks, such as striking the tip while
handling, can seriously damage the blade. Foreign objects
in the workpiece, such as wire or nails, can also cause tips
to crack or break off. Before using, always visually
examine the blade and tips for bent teeth, cracks,
breakage, missing or loose tips, or other damage. Do not
use if damage is suspected. Failure to heed safety
instructions and warnings can result in serious bodily
injury.

ALIGNING THE LASER GUIDE (Fig. P, Q, R)
This adjustment was made at the factory however
minor adjustment may be required before the tool is
used for the first time. Also, the laser alignment
should be checked periodically to verify accuracy. You
also have the option to change the laser projection to
the left, middle or right side of the blade according to
your preference when using the laser to guide the
cutting operation. When using the laser on an edge of
the workpiece, it may require recalibration to cut at the
left or right of the kerf.
For your own safety, never connect the plug to
power source outlet until all the adjustment steps
are complete and you have read and understood
the safety and operational instructions.
How to Check Laser-beam Alignment
1. Find a 90 ° square scrap workpiece and scribe a
90 ° line as the calibrating pattern and position the
workpiece on the table.
2. Turn on the laser and line up the laser beam with
the scribed line.
3. Lower the cutting head to verify the blade is parallel
to the side of the scribed line.
Parallel Laser Beam Adjustment (Fig. P)
Lower the cutting head so the blade is flush with the
side of the scribed line. Turn on the laser beam, loosen
the screw (4 - Fig. R) ¼ turn and adjust the thumbscrew
(2 - Fig. R) accordingly then retighten the screw (4).

miter saw.
• Avoid accidental starting
Make sure the switch is OFF before plugging the
miter saw into a power outlet.
16
PLAN YOUR WORK
Use the right tool. Don't force a tool or attachment
to do a job it was not designed to do. Use a
different tool for any workpiece that can't be held in
a solidly braced, fixed position.
CAUTION: This machine is NOT designed for cutting
masonry, masonry products & ferrous metals (steel,
iron, and iron-based metals.) Use this miter saw to cut
only wood, wood-like products, or soft metals like
aluminum. Other material may shatter, bind the blade,
or create other dangers. Remove all nails that may be
in the workpiece to prevent sparking that could cause a
fire.
DRESS FOR SAFETY
Any power tool can throw foreign objects into the eyes.
This can result in permanent eye damage. Everyday
eyeglasses have only impact resistant lenses and are
not safety glasses. Glasses or goggles not in
compliance with ANSI Z87.1 could seriously injure you
when they break.
• Do not wear loose clothing, gloves, neckties or
jewelry (rings, watches). They can get caught and
draw you into moving parts.
• Wear non-slip footwear.
• Tie back long hair.
• Roll long sleeves above the elbow.
• Noise levels vary widely. To avoid possible hearing
damage, wear ear plugs when using any miter
saw.
• For dusty operations, wear a dust mask along with
safety goggles.
INSPECT YOUR WORKPIECE
Make sure there are no nails or foreign objects in the
part of the workpiece being cut.
Plan your work to avoid small pieces that may bind,
or that are too small to clamp and get a solid grasp
on,
Plan the way you will grasp the workpiece from start to
finish. Avoid awkward operations and hand positions.
A sudden slip could cause your fingers or hand to move
into the blade.
DON'T OVER-REACH
Keep good footing and balance. Keep your face and
body to one side, out of the line of a possible kickback.
NEVER stand in the line of the blade.
Never cut freehand:
• Brace your workpiece firmly against the fence and
table stop so it will not rock or twist during the cut.
• Make sure there is no debris between the
workpiece and the table or fence.
• Make sure there are no gaps between the
workpiece, fence and table that will let the
workpiece shift during the cut.
• Keep the cut off piece free to move sideways after
it is cut off. Otherwise, it could get wedged against
the blade and thrown, possibly causing injury.
• Only the workpiece should be on the saw table.
• Secure work. Use clamps or a vise to help hold
the work when it's practical.
USE EXTRA CAUTION WITH LARGE OR ODD
SHAPED WORKPIECES.
• Use extra supports (tables, sawhorses, blocks, etc.)
for workpieces large enough to tip.
• Never use another person as a substitute for a
table extension, or as an additional support for a
workpiece that is longer or wider than the basic
miter saw table, or to help feed, support, or pull the
workpiece.
• Do not use this saw to cut small pieces. If the
workpiece being cut would cause your hand or
fingers to be within 8-1/2" inches of the saw blade
workpiece is too small. Keep hands and fingers out
of the "no hands zone" area marked on the saws
table.
• When cutting odd shaped workpieces, plan your
work so it will not bind in the blade and cause
possible injury. Molding, for example, must lie flat
or be held by a fixture or jig that will not let it move
when cut.
• Properly support round material such as dowel
rods, or tubing, which have a tendency to roll when
cut, causing the blade to "bite".
To avoid injury, follow all applicable safety instructions,
when cutting non-ferrous metals:
• Use only saw blades specifically recommended for
non-ferrous metal cutting.
• Do not cut metal workpieces that must be hand
held. Clamp workpieces securely.
• Cut non-ferrous metals only if you are under the
supervision of an experienced person.
WHEN SAW IS RUNNING
Don't allow familiarity from frequent use of your miter
saw to result in a careless mistake. A careless fraction
of a second is enough to cause a severe injury.
Before cutting, if the saw makes an unfamiliar noise or
vibrates, stop immediately. Turn the saw OFF. Unplug
the saw. Do not restart until finding and correcting the
problem.
17
BODY AND HAND POSITION (Fig. S)
Proper positioning of your body and hands when
operating the miter saw will make cutting easier and
safer. Never place hands near the cutting area. Place
hand at least 8-1/2" away from the path of the blade.
Hold workpiece firmly against the fence to prevent
movement toward the blade. Keep hands in position
until the trigger has been released and the blade has
completely stopped. Before making a cut, with the
power switch in the OFF position bring the saw blade
down to the workpiece to see the cutting path of the
blade.
• Keep children away. Keep all visitors a safe
distance from the miter saw. Make sure
bystanders are clear of the miter saw and
workpiece.
• Don't force the tool. It will do the job better and
safer at its designed rate. Feed the saw into the
workpiece slowly with a firm downward motion.
Before freeing jammed material
• Turn switch OFF.
• Unplug the miter saw.
• Wait for all moving parts to stop.
After finishing a cut
• Keep holding the power head down.
• Release the switch, and wait for all moving
parts to stop before moving your hands.
• If the blade doesn't stop within 6 seconds, unplug
the saw and follow refer to THE
TROUBLESHOOTING GUIDE.

Fig.
BB
CUTTING BOWED MATERIAL (Fig. AA)
A bowed workpiece must be positioned properly before
cutting. Do not position workpiece incorrectly or try to
cut the workpiece without the support of the fence. This
will cause the blade to bind and could result in personal
injury.
Fig. AA
WORKPIECE SUPPORT (Fig. BB)
Long pieces need extra support. The support should be
placed under the workpiece. Keep your hand holding
the workpiece positioned 8-1/2" or more away from the
blade. The support must let the workpiece lay flat on
the work table during the cutting operation.
NOTE: When mounted on a flat surface, the miter saw
table is 3-13/16 inches high.
NOTE: When mounted on a flat surface, the miter
saw table is 3-7/8" high.
When making multiple or repetitive cuts that result in
cut-off pieces of one inch or less, it is possible for the
saw blade to catch the cut-off piece and throw it out of
the saw or into the blade guard and housing, possibly
causing damage or injury. To minimize this risk, turn off
the machine, wait until the blade comes to a complete
stop, unplug the unit & remove the cut pieces.
AUXILARY WOOD FENCE (Fig. CC)
Holes are provided in the saw fence to attach an
auxiliary wood fence (this provides additional depth of
cut). This fence should be constructed of straight
auxiliary wood approximately 3/4 inch thick by 2-1/2
inches high by 21 inches long. Attach the wood fence
securely and make a full depth cut to make a blade slot.
Check for interference between the wood fence and the
lower blade guard. Adjust if necessary.

before power is applied to the saw.
CUTTING CROWN MOLDING (FIG. EE, FF)
Your compound miter saw is suited for the difficult task
of cutting crown molding. To fit properly, crown molding
must be compound-mitered with extreme accuracy. The
two surfaces on a piece of crown molding that fit flat
against the ceiling and wall are at angles that, when
added together, equal exactly 90 °.
Most crown molding has a top rear angle (the section
that fits flat against the ceiling) of 52°and a bottom rear
angle (the section that fits flat against the wall) of 38 ° .
In order to accurately cut crown molding for a 90 ° inside
or outside corner, lay the molding with its broad back
surface flat on the saw table.
When setting the bevel and miter angles for compound
miters, remember that the settings are interdependent;
changing one changes the other, as well. Also keep in
mind that the angles from crown molding are very easy
for these angles to shift slightly, all settings should be
tested on scrap molding.
Use a safety clamping vise, whenever possible, and
place tape on the area being clamped to avoid marks.

MAINTENANCE
DANGER
Never put lubricants on the blade while it is spinning.
To avoid fire or toxic reaction, never use gasoline,
naphtha acetone, lacquer thinner or similar highly
volatile solvents to clean the miter saw.
To avoid injury from unexpected starting or electrical
shock, unplug the power cord before working on the
saw.
For your safety, this saw is double-insulated. To avoid
electrical shock, fire or injury, use only parts identical to
those identified in the parts list. Reassemble exactly as
the original assembly to avoid electrical shock.
REPLACING CARBON BRUSHES (FIG. GG)
The carbon brushes furnished will last approximately 50
hours of running time, or 10,000 ON/OFF cycles.
Replace both carbon brushes when either has less than
1/4" length of carbon remaining, or if the spring or wire
is damaged or burned. To inspect or replace brushes,
first unplug the saw. Then remove the black plastic cap
(1) on the side of the motor (2). Remove the cap
cautiously, because it is spring-loaded. Then pull out
the brush and replace. Replace the other side in the
same manner. To reassemble, reverse the procedure.
The ears on the metal end of the assembly go in the
same hole the carbon part fits into. Tighten the cap
snugly, but do not overtighten.
NOTE: To reinstall the same brushes, first make sure
the brushes go back in the way they came out. This will
avoid a break-in period.
Fig. GG
LOWER BLADE GUARD
Do not use the saw without the lower blade guard. The
lower blade guard is attached to the saw for your
protection. Should the lower guard become damaged,
do not use the saw until the damaged guard has been
replaced. Develop a regular check to make sure the
lower guard is working properly. Clean the lower guard
of any dust or buildup with a damp cloth.
CAUTION: Do not use solvents on the guard. They
could make the plastic "cloudy" and brittle.
When cleaning the lower guard, unplug the saw from
the power source receptacle to avoid unexpected
startup.
SAWDUST
Periodically, sawdust will accumulate under the work
table and base. This could cause difficulty in the
movement of the worktable when setting up a miter cut.
Frequently blow out or vacuum up the sawdust.
If blowing sawdust, wear proper eye protection to keep
debris from entering eyes.
LUBRICATION
All the motor bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of
the unit under normal operating conditions; therefore,
no further lubrication is required.
Lubricate the Following as Required:
Chop pivot: light machine oil or aerosol will penetrate
from the ends of the junction points. A qualified service
technician can remove the pivot upstop to relieve
tension, and the 2 metric set screws holding the shaft,
in order to drive the shaft about 3/4" right. Exposed
surfaces are lubricated with automotive type oil.
Central pivot of plastic guard: Use light household oil
(sewing machine oil ) on metal-to-metal or
metal-to-plastic guard contact areas as required for
smooth, quiet operation. Avoid excessive oil, to which
sawdust will cling.
Link: (which actuates the lower guard movement) may
be oiled at the rear pivot, greased at ball bearing
contact, and oiled where the link actuates the acetyl
roller of the lower guard, if the down chop motion is
hard to start.
