INTRODUCTION

T

Your saw has many features for making cutting
operations more pleasant and enjoyable. Safety,

performance and dependability have been given top
priority in the design of this saw making it easy to
maintain and operate.

^ Look for this symbol to point out important safety precautions. It means attention!!! Your

safety Is inyolved.

A WARNING:

The operation of.any power tool can result in foreign objects being thrown into your eyes,
which can result in severe eye damage. Before beginning power tool operation, always
wear safety goggles or safety glasses with side shields and a full face shield when needed.
We recommend Wide Vision Safety Mask for use over eyeglasses or standard safety
glasses with side shields, available at Sears Retail Stores.

CAUTION: Carefully reakf through this entire
owner’s manual before using your new saw. Pay
close attention to the Rules For Safe Operation,
and all Safety Alert Symbols including Danger,
Warning and Caution. If you use your saw

properly and only for what it is intended, you will

enjoy years of safe, reliable service.

RULES FOR SAFE OPERATION

The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols, and
the explanations with them, deserve your careful attention and understanding. The safety warnings do

not by themselves eliminate any danger. The instructions or warnings they give are not substitutes for
proper accident prevention measures.

DOUBLE INSULATION

Double insulation is a concept in safety, in electric
power tools, which eliminates the need for the usual
three-wire grounded power cord. All exposed metal
parts are isolated from internal metal motor
components with protecting insulation. Double
insulated tools do not need to be grounded.

IMPORTANT

Servicing requires extreme care and knowledge of the
system and ^ould be performed only by a qualified
service technician. For service we suggest you return
the tool to your nearest Sears store for repair. Always
use original factory replacement parts when servicing.

/k WARNING: Do not attempt to operate this tool

until you have read thoroughly and understand
completely all instructions, safety rules, etc.
contained in this manual. Failure to comply can
result in accidents involving fire, electric shock,
or serious personal injury. Save owner's manual
and review frequently for continuing safe
operation, and instructing others who may use
this toot.

READ ALL INSTRUCTIONS

■ KNOW YOUR POWER TOOL. Read the owner's

manual carefully. Learn №e saw's applications
and limitations as well as the specific potential
hazards related to this tool,

■ GUARD AGAINST ELECTRICAL SHOCK BY
PREVENTING BODY CONTACT WITH
GROUNDED SURFACES. For example; pipes,

radiators, ranges, refrigerator enclosures.

■ KEEP GUARDS IN PLACE and in good working
order.

■ REMOVE ADJUSTING KEYS AND

WRENCHES. Get in the habit of checking to see

that hex keys and adjusting wrenches are
removed from tool before turning on saw.

KEEP THE WORK AREA CLEAN. Cluttered
work areas and work benches invite accidents.
DO NOT leave tools or pieces of wood on the
saw while it is in operation.

DO NOT USE IN DANGEROUS ENVIRON
MENTS. Do not use power tools near gasoline or

other flammable liquids, in damp or wet loca

tions, or expose them to rain. Keep the work
area well lit.

KEEP CHILDREN AND VISITORS AWAY. All
visitors should wear safety glasses and be kept a
safe distance from work area. Do not let visitors
contact tool or extension cord while operating.

MAKE WORKSHOP CHILD-PROOF with
padlocks and master switches, or by removing
starter keys.

better and safer at the rate for which it was

designed.

USE THE RIGHT TOOL. Do not force the tool or
attachment to do a job it was not designed for.

Don't use it for a purpose not intended.

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 voitage resulting in loss of power
and overheating. A wire gage size (A.W.G.) of at

least 14 is recomnnended 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 non^ip 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 lenses; 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. If 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 properiy 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

leave tool until it comes to a compiete 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 10 in.

KEEP BLADES CLEAN, SHARP AND WITH
SUFRCIENT SET. Shaqs 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.

RULES FOR SAFE OPERATION (Continued)

ALWAYS SUPPORT LONG WORKPIECES to
minimize risk of blade lynching 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 lengtii 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 tabie arKf position it firmly against the

fence as a backstop. Always use the fence.

NEVER hand hold a workpiece that is too smalt

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 arxj 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 leave 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 wilt 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.

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.

RULES FOR SAFE OPERATION (Continued)

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.

STAY ALERT AND EXERCISE CONTROL

Watch what you are doing and use common
sense. Do not operate tool when you are tired.

Do not rush.

Your compound miter saw has been adjusted at the
factory for making very accurate cuts. However, some
of the components might have been bumped out of

alignment during shipping. Also, over a period of time,

re-adjustment will probably become necessary due to

wear. After unpacking your saw, check the following

adjustments before you begin using saw. Make any

re-adjustments 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.

Note: Many of the illustrations in this manual show

only portions of your compound miter saw. This is

intentional so tiiat 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 tiiroat 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 throat plate will then be wide enough
to allow the blade to pass through it at any angle from

0 to 45 degrees.

ADJUSTMENTS

Using a 10 mm wrench or adjustable wrench,
loosen the lock nut securing positive stop adjust'
ment screw. Also loosen bevel lock knob.

Adjust positive stop adjustment screw to bring

saw blade into alignment with the square. See

Figure 24.

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 sup
port.

Note: The miter table support is located inside miter
table.

The depth stop is factory set to provide meiximum
cutting capacity for the 8-1/4 in. saw blade provided
with your saw. Therefore, the saw blade provided
should never need adjustments.

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 cuthng

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.

■ Retighten bevel lock knob. Next, retighten lock nut
securing the positive stop adjustment screw.

Recheck blade-to-table alignment.

Note: The above procedure can be used to check

blade squareness of the saw blade to the miter

table at both 0° and 45° angles.

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 a Sears store or
repair center to avoid risk of personal injury.

BEVEL PIVOT ADJUSTMENT

■ Your compound miter saw should bevel easily by
loosening bevel lock knob and tilting 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 or repair center
to avoid risk of personal injury.

A 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 provided to adjust the
depth stop adjustment screw. The saw blade is
lowered by turning the screw counter-clockwise
and raised by turning the screw clockwise.

APPLICATIONS

(Use only for the purposes listed below)

■ Cross cuttir>g wood and plastic.

■ Cross cutting miters, joints, etc. for picture frames,
moldings, door casings, and fine joinery.

Note: The 100 tooth crosscut blade provided is fine
for most wood cutting operations. For fine joinery cuts
or cutting plastic, use one of the accessory blades
available from your nearest Sears store.

A WARNING: Before starting any cutting

operation, clamp or bolt your compound miter
saw to a workbench. Never operate your miter
saw on the floor or in a crouched position.

Failure to heed this warning can result in serious
personal injury.

■ 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

iV 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 bindirvg the blade will
cause motor stalling and kickback. This situation
could cause an accident resulting in possible
serious personal injury.

Note: You can quickly locate 0°, 22-1/2° left or
right, and 45° left or right on the scale. The miter

table can be seated in one of the positive stop

notches, located in the miter table frame.

iV WARNING: To avoid serious personal injury,

always push the miter table clamp back down
before making a cut. Failure to do so could result
in movement of the miter table while making a
cut.

20

OPERATION

■ 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 fence and
miter table. A bevel cut is made with the miter table
set at the zero degree position arKt the blade set at an
angle between 0* and 45“.

INDICATOR

POINT

Place the workpiece flat on the miter table with

one edge securely against the fer>ce. 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 optional work clamp
or a C-clamp to secure the workpiece when
possible. See Figure 26.

I WARNING: To avoid serious personal injury,

^ keep your hands outside the no hands zone; at

least 3 in. from blade. Never perform any cutting

COMPOUND MITER CUT

See Figures 29 and 30.

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 miter table must be

rotated to the correct angle and the saw 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 toge№er, 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°.

CEIUNG

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 com­pourrd miters, remember that frie 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.

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.

OPERATION

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
completon of the cut.

CUTTING WARPED MATERIAL

See Figures 33 and 34.

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.

27

MAINTENANCE

iV WARNING: When serwcing, 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.

A 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 posable 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.

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.

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 №e tool will draw.
A wire gage size (A.W.G.) of at least 16 is recom

mended for an extension cord 50 feet or less in
length. When working outdoors, use an extension
cord that is suitaWe for outdoor use. The cord's Jacket
will be marked WA.

ÉL 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.

A WARNING: Check extension cords before each

use. If damaged, replace immediately. Never use

tool with a damaged cord since touchir^ the

damaged area could cause electrical shock
resulting in serious injury.

A 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.

28

MAINTENANCE

/k WARNING: To ensure safely 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 35.

Your saw has externally accessible brush assemblies

that should be periodically checked for wear.

Proceed as follows when replacement is required:

■ Unplug your saw.

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 botii brushes when
ei№er 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.
