RULES FOR SAFE OPERATION (Continued)
USE THE 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. A wire gage size (A.W.G.) of at
ieast 14 is recommended for an extension cord
25 feet or less in length. If in doubt, use the next
heavier gage. The smaller the gage number, the
heavier the cord.
INSPECT EXTENSION CORDS PERIODI
CALLY and replace if damaged.
DRESS PROPERLY. Do not wear loose clothing,
gloves, neckties, rings, bracelets, or other
jewelry. They can get caught and draw you into
moving parts. Rubber gloves and nonslip foot
wear are recommended when working outdoors.
Also wear protective hair covering to contain long
hair.
ALWAYS WEAR SAFETY GLASSES WITH
SIDE SHIELDS. Everyday eyeglasses have only
impact-resistant ienses; they are NOT safety
glasses.
PROTECT YOUR LUNGS. Wear a face or dust
mask if the cutting operation is dusty.
PROTECT YOUR HEARING. Wear hearing
protection during extended periods of operation.
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.
DO NOT OVERREACH. Keep proper footing and
balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools
sharp and clean for better and safer perfor
mance. Follow instructions for lubricating and
changing accessories.
DISCONNECT ALL TOOLS. When not in use,
before servicing, or when changing attachments,
blades, bits, cutters, etc., all tools should be
disconnected.
AVOID ACCIDENTAL STARTING. Be sure
switch is off when plugging in.
USE RECOMMENDED ACCESSORIES. The
use of improper accessories may cause risk of
injury.
NEVER STAND ON TOOL. Serious injury could
occur if the tool is tipped or if the blade is unin
tentionally contacted.
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 a qualified service technician at a Sears store
to avoid risk of personal injury.
NEVER LEAVE TOOL RUNNING UNAT
TENDED. TURN THE POWER OFF. Do not
ieave tool until it comes to a complete stop.
FIRMLY CLAMP OR BOLT your miter saw to a
workbench or table at approximately hip height.
USE ONLY CORRECT BLADES. Do not use
blades with incorrect size holes. Never use blade
washers or blade bolts that are defective or
incorrect. The maximum blade capacity of your
saw is 12 in.
KEEP BLADES CLEAN, SHARP AND WITH
SUFFICIENT SET. Sharp blades minimize
stalling and kickback.
DO NOT REMOVE THE SAW'S BLADE
GUARDS. Never operate the saw with any guard
or cover removed. Make sure all guards are
operating properly before each use.
KEEP HANDS AWAY FROM CUTTING AREA.
Keep hands away from blades. Do not reach
underneath work or around or under the blade
while blade is rotating. Do not attempt to remove
cut material when blade is moving.
WARNING: Blade coasts after turn off.
DO NOT ABUSE CORD. Never yank cord to
disconnect it from receptacle. Keep cord from
heat, oil, and sharp edges.
INSPECT TOOL CORDS PERIODICALLY and if
damaged, have repaired by a qualified service
technician at a Sears store. Stay constantly
aware of cord location and keep it well away
from the rotating blade.
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.
DO NOT USE TOOL IF SWITCH DOES NOT
TURN IT ON AND OFF. Have defective switches
replaced by a qualified service technician at a
Sears store.
KEEP TOOL DRY, CLEAN, AND FREE FROM
OIL AND GREASE. Always use a clean cloth
when cleaning. Never use brake fluids, gasoline,
petroleum-based products, or any solvents to
clean tool.
Page 5
RULES FOR SAFE OPERATION (Continued)
ALWAYS SUPPORT LONG WORKPIECES to
minimize risk of blade pinching and kickback.
Saw may slip, walk, or slide while cutting long or
heavy boards.
BEFORE MAKING A CUT, BE SURE ALL
ADJUSTMENTS ARE SECURE.
GUARD AGAINST KICKBACK. Kickback occurs
when the blade stalls rapidly and workpiece is
driven back towards the operator. It can pull your
hand into the blade resulting in serious personal
injury. Stay out of blade path and turn switch off
immediately if blade binds or stalls.
AVOID CUTTING NAILS. Inspect for and
remove all nails from lumber before cutting.
ALWAYS USE A CLAMP to secure the work
piece when possible.
NEVER TOUCH BLADE or other moving parts
during use.
NEVER START A TOOL WHEN THE BLADE IS
IN CONTACT WITH WORKPIECE. Allow motor
to come up to full speed before starting cut.
MAKE SURE THE MITER TABLE AND SAW
ARM (BEVEL FUNCTION) ARE LOCKED IN
POSITION BEFORE OPERATING YOUR SAW.
Lock the miter table by securely tightening the
miter lock handle. Lock the saw arm (bevel
function) by securely tightening the bevel lock
knob.
NEVER USE A LENGTH STOP ON THE FREE
SCRAP END OF A CLAMPED WORKPIECE.
NEVER hold onto or bind the free scrap end of
the workpiece in any operation. If a work clamp
and length stop are used together, they must
both be installed on the same side of the saw
table to prevent the saw from catching the loose
end and kicking up.
NEVER cut more than one piece at a time. DO
NOT STACK more than one workpiece on the
saw table at a time.
NEVER PERFORM ANY OPERATION "FREE
HAND". Always place the workpiece to be cut on
the miter table and position it firmly against the
fence as a backstop. Always use the fence.
NEVER hand hold a workpiece that is too small
to be clamped. Keep hands clear of the no hands
zone.
NEVER reach behind, under, or within three
inches of the blade and its cutting path with your
hands and fingers for any reason.
NEVER reach to pick up a workpiece, a piece of
scrap, or anything else that is in or near the
cutting path of the blade.
AVOID AWKWARD OPERATIONS AND HAND
POSITIONS where a sudden slip could cause
your hand to move into the blade. ALWAYS
make sure you have good balance. NEVER
operate your miter saw on the floor or in a
crouched position.
NEVER stand or have any part of your body in
line with the path of the saw blade.
ALWAYS release the power switch and allow the
saw blade to stop rotating before raising it out of
the workpiece.
DO NOT TURN THE MOTOR SWITCH ON AND
OFF RAPIDLY. This could cause the saw blade
to loosen and could create a hazard. Should this
ever occur, stand clear and allow the saw blade
to come to a complete stop. Disconnect your saw
from the power supply and securely retighten the
blade bolt.
REPLACEMENT PARTS. All repairs, whether
electrical or mechanical, should be made by
qualified service technician at a Sears store.
WARNING: When servicing use only identical
Craftsman replacement parts. Use of any other
parts may create a hazard or cause product
damage.
NEVER USE IN AN EXPLOSIVE ATMO
SPHERE. Normal sparking of the motor could
ignite fumes.
NEVER ieave the miter saw unattended while
connected to a power source.
POLARIZED PLUGS. To reduce the risk of
electric shock, this tool has a polarized plug (one
blade is wider than the other). This plug will fit in
a polarized outiet only one way. If the plug does
not fit fully in the outiet, 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.
IF ANY PART OF THIS MITER SAW IS MISS
ING or should break, bend, or fail in any way, or
should any electrical component fail to perform
properly, shut off the power switch, remove the
miter saw plug from the power source and have
damaged, missing, or failed parts replaced
before resuming operation.
DO NOT OPERATE THIS TOOL WHILE UN
DER THE INFLUENCE OF DRUGS, ALCOHOL,
OR ANY MEDICATION.
ALWAYS STAY ALERT! Do not allow familiarity
(gained from frequent use of your saw) to cause
a careless mistake. ALWAYS REMEMBER that
a careless fraction of a second is sufficient to
inflict severe injury.

factory for making very accurate cuts. However, some
of the components might have been jarred out of
alignment during shipping. Also, over a period of time,
readjustment will probably become necessary due to
wear. After unpacking your saw, check the following
adjustments before you begin using saw. Make any
readjustments that are necessary and periodically
check the parts alignment to make sure that your saw
is cutting accurately.
WARNING: Your saw should never be
connected to power supply when you are
assembling parts, making adjustments, installing
or removing blades, or when not in use.
Disconnecting your saw will prevent accidental
starting that could cause serious injury.

ADJUSTMENTS
Note: Many of the illustrations in this manual show
only portions of your compound miter saw. This is
intentional so that we can clearly show points being
made in the illustrations. Never operate your saw
without all guards securely in place and in good
operating condition.
CUTTING A SLOT IN THE ZERO
CLEARANCE THROAT PLATE
In order to use your compound miter saw, you must
cut a slot through the zero clearance throat plate to
allow for blade clearance. To cut the slot, set your
saw at 0 degrees miter, turn saw on and allow the
blade to reach full speed, then carefully make a
straight cut as far as it will go through the throat plate.
Turn your saw off and allow the blade to come to a
complete stop before raising the saw arm.
Next, adjust the bevel angle to 45 degrees, turn your
saw on and allow the blade to reach full speed, then
carefully make another cut through the zero clearance
throat plate. The slot in the throat plate will then be
wide enough to allow the blade to pass through it at
any angle from 0 to 45 degrees.

PIVOT ADJUSTMENTS
Note: These adjustments were made at the factory
and normally do not require readjustment.
TRAVEL PIVOT ADJUSTMENT
■ The saw arm should rise completely to the up
position by itself.
■ If the saw arm does not raise by itself or if there is
play in the pivot joints, have saw repaired by a
qualified service technician at your nearest Sears
store to avoid risk of personal injury.
BEVEL PIVOT ADJUSTMENT
■ Your compound miter saw should bevel easily by
loosening the bevel lock knob and tilting the saw
arm to the left.
■ If movement is tight or if there is play in the pivot,
have saw repaired by a qualified service techni
cian at your nearest Sears store to avoid risk of
personal injury.
DEPTH STOP
The depth stop limits the blade's downward travel. It
allows the blade to go below the miter table enough to
maintain full cutting capacities. The depth stop
positions the blade 1/4 in. from the miter table
support.
Note: The miter table support is located inside miter
table.
The depth stop is factory set to provide maximum
cutting capacity for the 12 in. saw blade provided with
your saw. Therefore, the depth stop should not need
an adjustment for the saw blade provided.
However, when the diameter of the blade has been
reduced due to sharpening, it may be necessary to
adjust the depth stop to provide maximum cutting
capacity. Also, when a new blade is installed, it is
necessary to check the clearance of the blade to the
miter table support before starting the saw. Make
adjustments if needed.
DEPTH STOP ADJUSTMENTS
See Figure 25.
■ Unplug your saw.
WARNING: Failure to unplug your saw could
result in accidental starting causing possible
serious personal injury.
■ To adjust the depth stop use a 17 mm wrench or
adjustable wrench and loosen the hex nut at the
rear of the miter saw arm.
■ Use the 5 mm hex key wrench provided to adjust
the depth stop adjustment screw. The saw blade
is lowered by turning the screw counterclockwise

Failure to heed this warning can result in serious
personal injury.
CUTTING WITH YOUR COMPOUND
MITER SAW
^ WARNING: When using a work clamp or
C-clamp to secure your workpiece, clamp
workpiece on one side of the blade only. The
workpiece must remain free on one side of the
blade to prevent the blade from binding in
workpiece. The workpiece binding the blade will
cause motor stalling and kickback. This situation
could cause an accident resulting in possible
serious personal injury.

■ Lower the blade into the zero clearance throat
plate of the miter table. Check blade clearance
and maximum cutting distance (distance from
fence where blade enters) to front of miter table
slot.
■ Readjust if necessary.
A WARNING: Do not start your compound miter
saw without checking for interference between
the blade and the miter table support. Damage
could result to the blade if it strikes the miter
table support during operation of the saw.
■ Tighten the hex nut with a 17 mm wrench or
adjustable wrench.
■ To prevent the depth stop adjustment screw from
turning while tightening the hex nut, carefully hold
it with the hex key while tightening the hex nut.
APPLICATIONS
(Use only for the purposes listed below)
■ Cross cutting wood and plastic.
■ Cross cutting miters, joints, etc. for picture frames,
moldings, door casings, and fine joinery.
Note: The blade provided is fine for most wood
cutting operations, but for fine joinery cuts or cutting
plastic, use one of the accessory blades available
from your nearest Sears store.
CROSSCUTTING
See Figure 26.
A crosscut is made by cutting across the grain of the
workpiece. A straight crosscut is made with the miter
table set at the zero degree position. Miter crosscuts
are made with the miter table set at some angle other
than zero.
TO CROSSCUT WITH YOUR MITER

■ Slowly lower the blade into and through the
workpiece. See Figure 26.
■ Release the switch trigger and allow the saw
blade to stop rotating before raising the blade out
of workpiece. Wait until the electric brake stops
blade from turning before removing the workpiece
from the miter table.
BEVEL CUT
See Figures 27 and 28.
A bevel cut is made by cutting across the grain of the
workpiece with the blade angled to the workpiece. A
straight bevel cut is made with the miter table set at
the zero degree position and the blade set at an angle
between 0° and 45°.
Place the workpiece flat on the miter table with
one edge securely against the fence. If the board
is warped, place the convex side against the
fence. If the concave edge of a board is placed
against the fence, the board could collapse on the
blade at the end of the cut, jamming the blade.
See Figures 33 and 34.
When cutting long pieces of lumber or molding,
support the opposite end of the stock with a roller
stand or with a work surface level with the saw
table.
Align cutting line on the workpiece with the edge
of saw blade.
Grasp the stock firmly with one hand and secure
it against the fence. Use the work clamp or a Cclamp to secure the workpiece when possible.
See Figure 26.
^ WARNING: To avoid serious personal injury,
^ keep your hands outside the no hands zone; at
least 3 in. from blade. Never perform any cutting
operation freehand (without holding workpiece
against the fence). The blade could grab the
workpiece if it slips or twists.
Before turning on the saw, perform a dry run of the
cutting operation just to make sure that no
problems will occur when the cut is made.

COMPOUND MITER CUT
A compound miter cut Is a cut made using a miter
angle and a bevel angle at the same time. This type of
cut Is used to make picture frames, cut molding, make
boxes with sloping sides, and for certain roof framing
cuts.
To make this type of cut the control arm on the miter
table must be rotated to the correct angle and the saw
f
arm must be tilted to the correct bevel angle. Care
should always be taken when making compound miter
setups due to the Interaction of the two angle settings.
Adjustments of miter and bevel settings are Interde
pendent with one another. Each time you adjust the
miter setting you change the effect of the bevel
setting. Also, each time you adjust the bevel setting
you change the effect of the miter setting.
It may take several settings to obtain the desired cut.
The first angle setting should be checked after setting
the second angle, since adjusting the second angle
affects the first.
Once the two correct settings for a particular cut have
been obtained, always make a test cut In scrap
material before making a finish cut In good material.

OPERATION
CUTTING CROWN MOLDING
Your compound miter saw does an excellent job of
cutting crown molding. In general, compound miter
saws do a better job of cutting crown molding than
any other tool made.
In order to fit properly, crown molding must be com
pound mitered with extreme accuracy.
The two contact surfaces on a piece of crown molding
that fit flat against the ceiling and the wall of a room
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°.
LAYING MOLDING FLAT ON THE
MITER TABLE
See Figure 32.
To use this method for accurately cutting crown
molding for a 90° inside or outside corner, lay the
molding with its broad back surface flat on the miter
table and against the fence.
When setting the bevel and miter angles for com
pound miters, remember that the settings are interde
pendent; changing one angle changes the other angle
as well.
Keep in mind that the angles for crown moldings are
very precise and difficult to set. Since it is very easy
for these angles to shift, all settings should first be
tested on scrap molding. Also most walls do not have
angles of exactly 90°, therefore, you will need to fine
tune your settings.
25
Page 26
OPERATION
When cutting crown molding by this method the bevel
angle should be set at 33.85°. The miter angle should
be set at 31.62° either right or left, depending on the
desired cut for the application. See the chart below for
correct angle settings and correct positioning of crown
molding on miter table.
The settings in the chart below can be used for cutting
All Standard (U.S.) crown molding with 52° and 38°
angles. The crown molding is placed flat on the miter
table using the compound features of your miter saw.

Type of Cut
When cutting warped material, always make sure it is
positioned on the miter table with the convex side
against the fence as shown in figure 33.
If the warped material is positioned the wrong way as
shown in figure 34, it will pinch the blade near the
completion of the cut.

A WARNING: To avoid a kickback and to avoid
serious personal injury, never position the
concave edge of bowed or warped material
against the fence.
CLAMPING WIDE WORKPIECES

MAINTENANCE
^ WARNING: When servicing, use only identical
Craftsman replacement parts. Use of any other
part may create a hazard or cause product
damage.
GENERAL
Avoid using solvents when cleaning plastic parts.
Most plastics are susceptible to damage from various
types of commercial solvents and may be damaged
by their use. Use clean cloths to remove dirt, carbon
dust, etc.
WARNING: Do not at any time let brake fluids,
gasoline, petroleum-based products, penetrating
oils, etc. come in contact with plastic parts. They
contain chemicals that can damage, weaken or
destroy plastic.
It has been found that electric tools are subject to
accelerated wear and possible premature failure when
they are used on fiberglass boats, sports cars,
wallboard, spackling compounds, or plaster. The
chips and grindings from these materials are highly
abrasive to electric tool parts such as bearings,
brushes, commutators, etc. Consequently, it is not
recommended that this tool be used for extended
work on any fiberglass material, wallboard, spackling
compounds, or plaster. During any use on these
materials it is extremely important that the tool is
cleaned frequently by blowing with an air jet.
EXTENSION CORDS
The use of any extension cord will cause some loss of
power. To keep the loss to a minimum and to prevent
tool overheating, use an extension cord that is heavy
enough to carry the current the tool will draw.
A wire gage size (A.W.G.) of at least 14 is recom
mended for an extension cord 25 feet or less in
iength. When working outdoors, use an extension
cord that is suitable for outdoor use. The cord's jacket
will be marked WA.
CAUTION: Keep extension cords away from the
cutting area and position the cord so that it will
not get caught on lumber, tools, etc., during
cutting operation.
^ 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.
WARNING: Always wear safety goggles or
safety glasses with side shields during power
tool operation or when blowing dust. If operation
is dusty, also wear a dust mask.
LUBRICATION
All of the 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.

MAINTENANCE
A WARNING: To ensure safety and reliability, all
repairs — with the exception of the externally
accessible brushes — should be performed by a
qualified service technician at a Sears store to
avoid risk of personal injury.
BRUSH REPLACEMENT
See Figure 36.
Your saw has externally accessible brush assemblies
that should be periodically checked for wear.
Proceed as follows when replacement is required:
■ Unplug your saw.
A WARNING: Failure to unplug your saw could
result in accidental starting causing serious
injury.
■ Remove brush cap with a screwdriver. Brush
assembly is spring loaded and will pop out when
you remove brush cap.
■ Remove brush assembly.
■ Check for wear. Replace both brushes when
either has less than 1/4 in. length of carbon
remaining. Do not replace one side without
replacing the other.
■ Reassemble using new brush assemblies. Make
sure curvature of brush matches curvature of
motor and that brush moves freely in brush tube.
■ Make sure brush cap is oriented correctly
(straight) and replace.
■ Tighten brush cap securely. Do not overtighten.
ACCESSORIES
^ WARNING: To prevent accidental starting that
could cause possible serious personal injury,
assemble all accessories to your saw before
connecting it to power supply. Saw should never
be connected to power supply when you are
assembling parts, making adjustments, installing
or removing blades or accessories, or when not
in use.
DUST BAG
See Figure 37.
The dust bag fits over the exhaust port on the upper
blade guard. To install it, remove the dust guide from
the exhaust port. Then, squeeze the two metal clips to
open the mouth of the bag and slide it on the exhaust
port. Release the clips. The metal ring in the bag
should lock in between the grooves on the exhaust
port. For more efficient operation, empty dust bag
when no more than half full. This will permit better air
flow through the bag.

TABLE EXTENSIONS
See Figures 38, 39, and 40.
If you plan to use both the stop block and miter clamp,
slide the stop block on the back arm of the desired
table extension first. Next slide the clamp support on
the same table extension. See Figure 38.
To install table extensions, insert the ends of the
extensions into the two holes in each side of the base.
See Figures 38 and 39.
Secure each clamp bracket in place with a clamp
bracket screw. The clamp bracket screw threads
through the clamp bracket and tightens against the
bottom of miter table, securing clamp bracket against
table extension.
STOP BLOCK
See Figures 38 and 41.
Secure them in place by positioning a clamp bracket
under each table extension beneath the miter table.
Orient each clamp bracket as shown in figure 40.

The stop block is useful as a stop for cutting multiple
pieces to the same length. It can be installed on either
table extension on either side of the saw base:
■ Slide the stop block on the back arm of either table
extension, then insert the table extension into the
saw base. See Figure 38.
■ Use the small wing screw to secure the stop block
to the table extension. See Figure 38.
■ Loosen the small wing screw and adjust the stop
block the desired distance from the blade for the
cut to be made.
■ Tighten small wing screw securely.
■ Make a test cut in scrap material and measure the
length of the workpiece.
■ Make any necessary adjustments.
^ WARNING: When using the work clamp with
the stop block, install the clamp on the stop block
side of the blade. This will eliminate the
possibility of the saw catching the loose end and
kicking up. Failure to heed this warning can
result in serious personal injury.
