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 yourproduct will draw. An undersized cord will cause

a drop in line voltage resulting in loss of powerand overheating. A wire gage size (A.WG.) of atleast 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, theheavier 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 intomoving 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 WITHSIDE SHIELDS. Everyday eyeglasses have only •impact-resistant lenses; they are NOT safetyglasses.

• PROTECT YOUR LUNGS. Wear a face or dustmask if the cutting operation is dusty. •

• PROTECT YOUR HEARING. Wear hearingprotectionduring extended periods of operation.

• SECURE WORK. Use clamps or a vise to holdwork 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 toolssharp 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 bedisconnected. •

• AVOID ACCIDENTAL STARTING. Be sure

switch is off when plugging in.

• USE RECOMMENDED ACCESSORIES. The

use of improper accessories may cause risk ofinjury.

• NEVER STAND ON TOOL. Serious injury couldoccur 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 damagedshould be carefully checked to determine that itwill operate properly and perform its intended

Note: The above procedure can be used to checkblade squareness of the saw blade to the mitertable at both 0° and 45° angles.

Your saw has three scale indicators, two on eitherside of the bevel scale and one on the miter scale.After squaring adjustments have been made, it maybe necessary to loosen the indicators screws andreset them to zero.

CUTTING A SLOT IN THE ZEROCLEARANCE THROAT PLATE

In order to use your compound miter saw, you mustcut a slot through the zero clearance throat plate toallow for blade clearance. To cut the slot, set yoursaw at 0 degrees miter, turn saw on and allow theblade to reach full speed, then carefully make astraight cut as far as it will go through the throat plate.Turn your saw off and allow the blade to come to acomplete stop before raising the saw arm.

Next, adjust the bevel angle to 45 degrees, turn yoursaw on and allow the blade to reach full speed, thencarefully make another cut through the zero clearancethroat plate. The throat plate willthen be wide enoughto allow the blade to pass through it at any angle fromO to 45 degrees.

Note: These adjustments were made at the factoryand normally do not require readjustment.

TRAVEL PIVOT ADJUSTMENT

• The saw arm should rise completely to the upposition by itself.

If the saw arm does not raise by itself or if there isplay in the pivot joints, have saw repaired by aqualified service technician at your nearest Searsstore to avoid risk of personal injury.

BEVEL PIVOT ADJUSTMENT

• Your compound miter saw should bevel easily byloosening the bevel lock knob and tilting the sawarm 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 ofpersonal injury.

DEPTH STOP

The depth stop limits the blade's downward travel. Itallows the blade to go below the miter table enough tomaintain 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 mitertable.

The depth stop is factory set to provide maximumcutting capacity for the 10 in. saw blade provided withyour saw. Therefore, the saw blade provided shouldnever need adjustments.

However, when the diameter of the blade has beenreduced due to sharpening, it may be necessary toadjust the depth stop to prov!de maximum cuttingcapacity. Also, when a new blade is installed, it isnecessary to check the clearance of the blade to themiter table support before starting the saw. Makeadjustments if needed.

DEPTH STOP ADJUSTMENTSSee Figure 25.


,_ WARNING: Failure to unplug your saw couldresult in accidental starting causing possibleserious personal injury.

• To adjust the depth stop use a 17 mm wrench oradjustable wrench and loosen the hex nut at therear of the miter saw arm.

Use the 5 mm hex key wrench provided to adjustthe depth stop adjustment screw. The saw bladeis lowered by turning the screw counter-clockwiseand raised by turning the screw clockwise.

CUTTING WITH YOUR COMPOUNDMITER SAW

A WARNING: When using a work clamp or

C-clamp to secure your workpiece, clamp

workpiece on one side of the blade only. Theworkpiece must remain free on one side of theblade to prevent the blade from binding in

workpiece. The workpiece binding the blade willcause motor stalling and kickback. This situationcould cause an accident resulting in possible

serious personal injury.

CROSSCUTTINGSee Figure 26.

A crosscut is made by cutting across the grain of theworkpiece. A straight crosscut is made with the mitertable set at the zero degree position. Miter crosscutsare made with the miter table set at some angle otherthan zero.

COMPOUND MITER CUT

A compound miter cut is a cut made using a miterangle and a bevel angle at the same time. This type ofcut is used to make picture frames, cut molding, makeboxes with sloping sides, and for certain roof framingcuts.

To make this type of cut the control arm on the mitertable must be rotated to the correct angle and the sawarm must be tilted to the correct bevel angle. Careshould always be taken when making 'compound mitersetups 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 themiter setting you change the effect of the bevelsetting. Also, each time you adjust the bevel settingyou 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 settingthe second angle, since adjusting the second angleaffects the first.

Once the two correct settings for a particular cut havebeen obtained, always make a test cut in scrapmaterial before making a finish cut in good material.

CUTTING CROWN MOLDING

Your compound miter saw does an excellent job ofcutting crown molding. In general, compound mitersaws do a better job of cutting crown molding thanany 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 moldingthat fit ftat against the ceiling and the wall of a roomare 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 againstthe wall) of 38 °.

To use this method for accurately cutting crownmolding for a 90 ° inside or outside corner, lay themolding with its broad back surface flat on the mitertable 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 angleas well.

Keep in mind that the angles for crown moldings arevery precise and difficult to set. Since it is very easyfor these angles to shift, all settings should first betested on scrap molding. Also most walls do not have

angles of exactly 90 °, therefore, you will need to finetune your settings.

_I, WARNING: When servicing, use only identicalCraftsman replacement parts. Use of any otherpart may create a hazard or cause productdamage.

GENERAL

Avoid using solvents when cleaning plastic parts.Most plastics are susceptible to damage from varioustypes of commercial solvents and may be damagedby their use. Use clean cloths to remove dirt, carbondust, etc.

,_, WARNING: Do not at any time let brake fluids,gasoline, petroleum-based products, penetratingoils, etc. come in contact with plastic parts. Theycontain chemicals that can damage, weaken ordestroy plastic.

It has been found that electric tools are subject toaccelerated wear and possible premature failure whenthey are used on fiberglass boats, sports cars,wallboard, spackling compounds, or plaster. Thechips and grindings from these materials are highlyabrasive to electric tool parts such as bearings,brushes, commutators, etc. Consequently, it is notrecommended that this tool be used for extendedwork on any fiberglass material, wallboard, spacklingcompounds, or plaster. During any use on thesematerials it is extremely important that the tool iscleaned frequently by blowing with an air jet.

LUBRICATION

All of the bearings in this tool are lubricated with asufficient amount of high grade lubricant for the life ofthe unit under normal operating conditions. Therefore,

no further lubrication is required.

EXTENSION CORDS

The use of any extension cord will cause some loss ofpower. To keep the loss to a minimum and to preventtool overheating, use an extension cord that is heavyenough 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 inlength. When working outdoors, use an extensioncord that is suitable for outdoor use. The cord's jacketwill be marked WA.

A CAUTION: Keep extension cords away from thecutting area and position the cord so that it willnot get caught on lumber, tools, etc., duringcutting operation.

WARNING: Check extension cords before eachuse. If damaged, replace immediately. Never usetool with a damaged cord since touching thedamaged area could cause electrical shockresulting in serious injury.

A WARNING: Always wear safety goggles orsafety glasses with side shields during powertool operation or when blowing dust. If operationis dusty, also wear a dust mask.
