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 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
???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.
MSECURE WORK. Use clamps or a vise to hold work when practical. It'ssafer than using your hand and it frees both hands to operate tool.
DO NOT OVERREACH. Keep proper footing and balance at all times.
mMAINTAIN 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.
MAVOID ACCIDENTAL STARTING. Be sure switch is off when plugging in.
mUSE 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 leave tool until it comes to a complete stop.
mRRMLY 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 sew is 10 in.
mKEEP BLADES CLEAN, SHARP AND WITH SUFRCIENT SET. Sharp blades minimize stalling and kickback.
mDO NOT REMOVE THE SAW'S BLADE GUARDS. Never operate the sew with any guard or cover removed. Make sure all guards are operating properly before each use.
mKEEP 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.
_k 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.
mINSPECT 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.
mUSE 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.
nDO 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,

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 CU'R'INGNAILS. 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. Look the miter table by securely tightening the miter lock handle. Look the sew 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 sew table to prevent the sew 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 workpiooe, 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 sew 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 sew blade to loosen and could create a hazard. Should this ever occur, stand clear and allow the sew 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 sew 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 electdcian 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 sew 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.

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 sedous injury.
Note: Many of the illustrations in this manual show only portions of your compound miter saw. This is intentional so that we can cleady 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 throat plate will then be wide enough to allow the blade to pass through it at any angle from
0 to 45 degrees.

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 seffing 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.

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 fiat 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 exacUy 90 ??, therefore, you will need to fine tune your settings.

Whencuttingcrownmolding by this method the bevel angle should be sot at 33.85 ??. The miter angle should be sot 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.

CUTTING WARPED MATERIAL
See Figures 33 and 34.
When cuffing 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.
WARNING: To avoid a kickback and to avoid serious personal injury, never position the
concave edge of bowed or warped material against the fence.

WARNING: When servicing, use only identical Craftsman replacement ports. 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,
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, usa 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 16 is recom- mended for an extension cord 50 feet or less in length. When working outdoors, use an extension cord that is suitable for outdoor use. The cord'sjacket will be marked WA.
&CAUTION: Keep extension cords away from the cuffing area and position the cord so that it will
not get caught on lumber, tools, etc., during cutting operation.
AWARNING: 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.
