INTRODUCTION

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.

A Look for this symbol to point out important safety precautions. It

means attention!!! Your safety is involved.

CAUTION: Carefully read 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.

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 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. Always wear eye protection which is

marked to comply with ANSI Z87.1.

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.

three-wire grounded power cord. All exposed metal
parts are isolated from interna! 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 should be performed only by a qualified
service technician. For service we suggest you return
the tool to your nearest Sears store or repair center for
repair. Always use original factory replacement parts
when servicing.

^ 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

RULES FOR SAFE OPERATION (Continued)

USE THE PROPER EXTENSION CORD. Make
sure your extension cord is in good condition.
Use only a cord 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 least 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.

miter lock handle. Lock the saw arm (bevel
function) by secureiy tightening the bevei 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.

Your compound miter saw has been adjusted at the
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.

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.

Your saw has three scale indicators, two on either
side of the bevel scale and one on the miter scale.
After squaring adjustments have been made, it may

be necessary to loosen the indicators screws and
reset them to zero.

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° 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°, 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°.

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 or repair center 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 or repair center

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 10 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 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 counter-clockwise
and raised by turning the screw clockwise.

^ 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 wrench while tightening the

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.

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.

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.

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 0’ position. Miter crosscuts are made
with the miter table set at some angle other than zero.

TO CROSSCUT WITH YOUR MITER SAW

■ Pull out the lock pin and lift saw arm to its full

height.

■ Loosen the miter lock handle. Rotate the miter
lock handle approximately one-half turn to the left

to loosen.

■ Press the miter lock plate down with your thumb
and hold.

■ Rotate the control arm until the pointer aligns with

the desired angle on the miter scale.

■ Release the miter lock plate.
Note: You can quickly locate 0", 22-1/2° left or

right, and 45° left or right by releasing the lock
plate as you rotate the control arm. The lock plate

will seat itself in one of the positive stop notches,

located in the miter table frame.

■ Tighten the miter lock handle securely.

WARNING: To avoid serious personal injury,
always tighten the miter lock handle securely
before making a cut. Failure to do so could result

in movement of the control arm or miter table

while making a cut.

19

OPERATION

■ Slowly lower the blade into and through the

workpiece. See Figure 26.

■ Ftelease 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°.

C-CLAMP

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.

Fig, 26

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. See Figure 31.
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.

^ WARNING: To avoid serious personai 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.
Grasp the saw handle firmly then squeeze the

switch trigger. Allow several seconds for the blade

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
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.

21

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 moiding than
any other tooi 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 moiding
that fit fiat 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 fiat against
the wail) 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 comer, 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 angies 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 moiding 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.

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.

CUTTING WARPED MATERIAL

See Figures 33 and 34.

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

CLAMPING WIDE WORKPIECES

See Figure 35.

When cutting wide workpieces such as a 2 in. x 6 in.,

boards should be clamped with a C-clamp as shown in

figure 35.

MAINTENANCE

^ WARNING: When sen/icing, use only identical

Craftsman replacement parts. Use of any other
part may create a hazard or cause product

damage.

GENERAL

Avoid using solvents vtrhen 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, wall

board, 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 recom
mended that this tool be used for extended work on
any fiberglass material, wallboard, spackling com
pounds, or plaster. During any use on these materials
it is extremely important that the tool is cleaned
frequently by blowing with an air jet.

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.

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.

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 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
length. 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.

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.
