better and more safely at the rate for which it was

designed.

• USE THE RIGHT TOOL FOR THE JOB. Do not force the tool or attachment to do a job it was not

designed for. Use it only the way it was intended.

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.

• INSPECT TOOL CORDS AND EXTENSION CORDS PERIODICALLY and, if damaged, have

repaired by a qualified service technician at a

Sears store or repair center. Stay constantly aware of cord location and keep Jtwell away from the moving blade.

• DRESS PROPERLY. Do not wear loose clothing,

gloves, neckties, rings, bracelets, or other

jewelry that can get caught and draw you into

movmg parts. Nonslip footwear is recommended. Also wear protective hair covering to contain long

hair. ALWAYS WEAR SAFETY GLASSES WITH

SIDE SHIELDS. Everyday eyeglasses have only impact-resistant lenses, they are NOT safety glasses.

WEAR A DUST MASK to keep from inhaling fine particles.

PROTECT YOUR HEARING. Wear hearing protection during extended periods of operation.

FIRMLY CLAMP OR BOLT your miter saw to a workbench or table at approximately hip height.

USE ONLY CORRECT BLADES. Use the right blade size, style and cutting speed for the mate-

nal and the type of cut. Do not use blades with mcorrect size 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 staihng 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 CUl-rlNG AREA.

Do not reach underneath work or in blade cutting

RULES FOR SAFE OPERATION (Continued)

BEFORE MAKING A CUT, be sure all adjust- ments are secure.

BE SURE BLADE PATH IS FREE OF 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 for any reason.

BE SURE THE BLADE CLEARS THE WORK- PIECE. Never start the saw with the blade

touching the workpiece. Allow motor to come up to full speed before starting out.

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 itscutting 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.

n 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 itout 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.

USE ONLY SEARS REPLACEMENT PARTS. All repairs, whether electrical or mechanical,

should be made by a qualified service technician at a Sears store or repair center.

WARNING: When servicing, use only identical

Craftsman replacement parts. Use of any other

parts may create a hazard or cause product

damage.

NEVER USE THIS TOOL IN AN EXPLOSIVE ATMOSPHERE. Normal sparking of the motor could ignite fumes.

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. Ifthe 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.

ALWAYS STAY ALERT! Do not allow familiarity

(gained from frequent use of your saw) to cause

a careless mistake. ALWAYS REMEMBER that

a careless fraction of a second is sufficient to

inflictsevere injury.

STAY ALERT AND EXERCISE CONTROL.

Watch what you are doing and use common

sense. Do not operate tool when you are tired.

Do not rush.

MAKE SURE THE WORK AREA HAS AMPLE

LIGHTING to see the work and that no obstruc-

tions will interfere with safe operation BEFORE

performing any work using your saw.

_ WARNING: Some dust created by power

sanding, sawing, grinding, drilling,and other construction activities contains chemicals known

to cause cancer, birth defects or other reproduc- tive harm. Some examples ofthese chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement

and other masonry products, and

• arsenic and chromium from chemically-

treated lumber.

Your risk from these exposures varies, depending

on how often you do this type of work. To reduce

your exposure to these chemicals, work in a well ventilated area and work with approved safety

equipment, such as those dust masks that are specially designed tofilter out microscopic

particles.

Arbor The shaft on which a blade or cutting tool is mounted.

Bevel Cut A cutting operation made with the blade at any angle

other than 90" to the miter table. Crosscut

A cutting or shaping operation made across the grain of the workpiece.

Compound Miter Cut A compound miter cut is a cut made using a miter angle and a bevel angle at the same time.

Freehand Performing a cut without using a fence, vise, fixture,

work clamp, or other proper device to keep the workpiece from twisting or moving during the cut.

Gum A sticky, sap based residue from wood products. Miter Cut

A cutting operation made with the blade at any angle other than 90" to the fence.

Resin

A sticky, sap base substance that has hardened.

Revolutions Per Minute (RPM)

The number of turns completed by a spinning object

in one minute.

Saw Blade Path The area over, under, behind, or in front of the blade. As it applies to the workpiece, that area which will be,

or has been, cut by the blade.

Set

The distance that the tip of the sawblade tooth is bent

(or set) outward from the face of the blade.

Throw-Back Throwing of a workpiece in a manner similar to a

kickback. Usually associated with a cause other than the kerr closing, such as a workpiece not being

against the fence, being dropped into the blade, or being placed inadvertently in contact with the blade.

Through Sawing Any cutting operation where the blade extends completely through the thickness of the workpiece.

Workpiece The item on which the cutting operation is being done. The surfaces of a workpiece are commonly referred to

as faces, ends, and edges.

Zero Clearance Throat Plate A plastic throat plate inserted in the miter table that

allows for blade clearance. When you make your first cut with your compound miter saw, the saw blade cuts

a slot through the throat plate the exact width ofthe blade. This provides for a zero clearance kerr that minimizes workpiece tear-out.

No Hands Zone

The area between the marked lines on the left and

right side of the miter table base. This zone is identified by no hands zone labels placed inside the

marked lines on the miter table base.
