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 putdoors. Also wear protective hair covering to contain long
hair. ALWAYS WEAR SAFETY GLASSES WITH
SIDE SHIELDS. Everyday eyeglasses have only impact-resistant ienses; 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 tooi.
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., ail 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 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.
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 12 in.
KEEP BLADES CLEAN, SHARP AND WITH SUFFICIENT SET. Sharp blades minimize stailing 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 white 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.

RULES FOR SAFE OPERATION (ContinuecQ
ALWAYS SUPPORT LONG WORKPIECES to minimize risk of blade pinching and kickback.
Saw may siip, waik, or siide whiie cutting iong or
heavy boards. BEFORE MAKING A CUT, BE SURE ALL
ADJUSTMENTS ARE SECURE. GUARD AGAINST KICKBACK. Kickback occurs
when the biade staiis rapidly and wol1фiece is
driven back towards the operator, it can puii your
har>d into the biade resuiting in serious personal injury. Stay out of blade path and turn switeh off immediately if blade binds or stalls.
AVOID CUTTING NAILS. Inspect tor 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 TNE 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 toe free scrap end of
toe workpiece in any operation. If a work damp
and length stop are used together, they must both be installed on toe same side of toe 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 toe 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 hartos
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 toe blade. ALWAYS make sure you have good balance. NEVER operate your miter saw on toe 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 toe saw blade to stop rotating before raising it out of the workpiece.

Your compound miter saw has been adjusted at the factory for making very accurate cuts. However, some of tee 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 tee following adjustments before you begin using saw. Make any readjustments that are necessary and periodically check tee 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 p^, 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 compourKi miter saw. This is intentional so that 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 throat plate to
allow for blade cleararrce. To cut the ^t, 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.

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 tile 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 su'm 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 taible support.
Note: ITie miter table support is located inside miter table.
The depth stop is factory set to provide maximum cutting capacity for the 12 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 cleararwe 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 Wade is lowered by turning the screw counter-clockwise and raised by turning the screw clockwise.

ADJUSTMENTS
■ Lower the blade into the zero clearance throat plate of the miter table. Check blade clearance and maximum cutting distance (distance from fence where biade enters) to front of miter tabie slot
■ Readjust if necessary.
A WARNING: Do not start your compound miter
saw without checking for interference between the blade and the miter tabie support. Damage could result to №e 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 white tightening the hex nut.

APPLICATIONS

(Use only for the purposes listed below)
■ Cross ojtting 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 ojserations, 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, bolt or nail your compound miter saw to a workbench. Never operate your miter saw on the floor or in a crouched position.
Failure to heed friis warning can result in serious personal injury.

CUTTING WITH YOUR COMPOUND MITER SAW

A 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 couid 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 tabie 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“, 15°, 22-1/2°,
31.62°, and 45° left or right by releasing the lock plate as you rotate frie 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.
ik WARNING: To avoid serious personal injury,
** ftiways tighten the miter lock handle securely
before making a cut. Failure to do so could result in movement of frie control arm or miter table while making a cut.
19
Page 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 26.
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 wifri the miter table set at the zero degree position and the blade set at an angle between 0" and 45“.
Place the workpiece flat on the miter table with
one edge securely against the fence. If the board
is waiped, 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 H^th 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-ciamp to secure the workpiece when possible. See Figure 26.
WARNING: To avoid serious personal 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 tumirig 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, press the lock-off tab down, then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.

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 toe miter table must be rotated to the correct angle and toe saw arm must be tilted to the correct bevel angle. Care
should always be taken when m£d<ing compound miter setups due to toe 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 toe 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 toe 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 materieti.

OPERATION

CUTTING CROWN MOLDING

Your compound miter saw does an excellent job of cutting crown molding. In gerreral, 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 exb'eme 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 rrolding 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°.
CEHJNG
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 toe bevel and miter angles for com pound miters, remember that toe settings are interde pendent; changing one angle changes toe 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 exar^y 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.

CUTTING WARPED MATERIAL

See Figures 33 and 34.
Fig. 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 completion of the cut.
iV WARNING: To avoid a kickback and to avoid
serious personal injury, never position the concave edge of bowed or warped material against the fence.

MAINTENANCE
WARNING: When servicing, use only identicat
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 №eir 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 acc^erated 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 №e 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, ete., during cutting operation.
WARNING: Check extension cords before each
use. If damaged, replace immediately. Never use tool wito 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.

MAINTENANCE
iW 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.

Your saw has externally accessible brush assemblies that should be periodicaiiy checked for wear.
Proceed as follovro 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 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.
