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.

READ ALL INSTRUCTIONS

KNOW YOUR POWER TOOL. Read the owner's

manual carefully. Learn the 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 piecesof wood on the saw

while it is in operation.

DO NOT USE IN DANGEROUS ENVIRON-

MENTS. Do not use power tools near gasoline or otherflammable liquids,in damp or wet locations, or expose them to rain. Keep the work area well

lit.

KEEP CHILDREN AND VISITORS AWAY. All visitors shoutd 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 pad- locks and master switches, or by removing starter

keys.

DO NOT FORCE THE TOOL. It will do the job

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 voltage resulting in loss of power

and overheating. A wire gage size (A.WG.) 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.

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-resistantlenses; 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 protectionduring 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. _1,

• DO NOT OVERREACH. Keep proper footing and

balance at a_Ltimes. •

• 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

unintentionally 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 leave tool untilitcomes 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 incorrectsize 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 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 whileblade is rotating. Do not attempt to remove

cut material whenblade 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 qualifiedservice

technicianat a Sears store. Stay constantly aware of cord location and keep it well away

from the rotatingblade USE OUTDOOR EXTENSION CORDS. When

tool isused outdoors,use only extension cords with approvedground connectionthatare

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 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. 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. Allrepairs, 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 ahazard 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 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.

• 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 111 (gained from frequent use of your saw) to cause

a careless mistake. ALWAYS REMEMBER that a careless fraction of a second issufficientto

inflictsevere injury. STAY ALERT AND EXERCISE CONTROL.

Watch what you are doingand use common sense. Do not operate tool when you are tired,

Do not rush.

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 loosenthe 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 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 willthen be wide enough to allow the blade to pass through it at any angle from O to 45 degrees.

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 posi-

tions 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 prov!de 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.

APPLICATIONS (Use onty for the purposes |isted below)

• Cross cutting wood and plastic.

• Cross cutting miters, joints, etc. for picture frames,

moldings, door casings, and fine joinery.

Note: The 104 tooth crosscut 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.

_1= 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 zero degree 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.

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 thetwo correctsettings for a particular cut have

been obtained, always make a test cut in scrap material before making a finish cut in good material.

TO MAKE A COMPOUND CUT WITH • YOUR MITER SAW:

• Pull outthe lockpin and lift saw armto itsfull •

height.

• Loosenthe miter lock handle. Rotate the miter lock

handle approximatelyone-half turn to the le_tto

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

• Rotate the controlarm until the pointer aligns with the desired angle on the miter scale.

• Release the miter lockplate. •

Note: You can quicklylocate0", 22-1/2" leftor right,and 45" leftorrightby releasingthe miter •

lock plate as you rotate the control arm. The miter lock plate willseat itselfin one of the positive stop notches, locatedin mitertable frame.

COMPOUND-ANGLE SETTINGS FOR POPULAR STRUCTURES

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 ftat 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.

Whencutting crown molding by this methodthe bevel

angle should be set at 33.85 °. The miter angle should

be set at 31.62° either rightor left, depending on the

desired cutfor the application. See the chart below for correct angle settingsand correct positioningofcrown

moldingon mitertable.

The settingsinthe chart below can be used for cutting All Standard (U.S.) crown molding with 52° and 38°

angles. The crownmoldingis placed flat on the miter table using the compoundfeatures of your miter saw.

When cuttingwarped 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.

_ WARNING: To avoid a kickback and to avoid

serious personal injury,never position the concave edge of bowed or warped material against the fence.

_I, 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.

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 issuitable 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.

_1= WARNING: To ensure safety and reliability, all

repairs -- with the exception of the externally

accessible brushes-- should be performedby a qualifiedservice technician at a Sears storeto avoid riskof personal injury,

Your saw has externally accessible brush assemblies that should be periodically checked for wear.

Proceed as follows when replacement is required:

• Unplug yoursaw.

_WARN|NG: Failure to unplug your saw could

result in accidental starting causing serious

injury.

• Remove brush cap with a screwdriver, Brush assembly is spring_oadedand will pop o_ 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.
