INTRODUCTION

Your saw has many features for making cutting
operations more pleasant and enjoyable. Safety,
performance and dependability have been given top
priority in the design of this saw making it easy to

maintain and operate.

A Look for this symbol to point out important safety precautions. It

means attention!!! Your safety is involved.

CAUTION: Carefully read through this entire

owner's manual before using your new saw. Pay
close attention to the Rules For Safe Operation,
and all Safety Alert Symbols including Danger,
Warning and Caution. If you use your saw
properly and only for what it is intended, you will
enjoy years of safe, reliable service.

A WARNING:

The operation of any power tool can result in foreign objects being thrown into your eyes,
which can result in severe eye damage. Before beginning tool operation, always wear safety
goggles or safety glasses with side shields and a full face shield when needed. We

recommend Wide Vision Safety Mask for use over eyeglasses or standard safety glasses

with side shields, available at Sears Retail Stores. Always wear eye protection which is

marked to comply with ANSI Z87.1.

RULES FOR SAFE OPERATION

The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols, and the

explanations with them, deserve your careful attention and understanding. The safety warnings do not by

themselves eliminate any danger. The instructions or warnings they give are not substitutes for proper accident

prevention measures.

DOUBLE INSULATION

Double insulation is a concept in safety, in electric
power tools, which eliminates the need for the usual
three-wire grounded power cord. All exposed metal
parts are isolated from interna! metal motor
components with protecting insulation. Double

insulated tools do not need to be grounded.

IMPORTANT

Servicing requires extreme care and knowledge of the
system and should be performed only by a qualified
service technician. For service we suggest you return
the tool to your nearest Sears store or repair center for
repair. Always use original factory replacement parts
when servicing.

^ WARNING: Do not attempt to operate this tool

until you have read thoroughly and understand
completely all instructions, safety rules, etc.
contained in this manual. Failure to comply can

result in accidents involving fire, electrical shock,
or serious personal injury. Save owner's manual
and review frequently for continuing safe
operation, and instructing others who may use
this tool.

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 it well 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

moving 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.

moving parts, breakage of parts, saw stability, mount

■ 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
rial and the type of cut. 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 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.

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. Aitow 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 tabie by securely tightening the
miter lock handle. Lock the saw arm (bevel
function) by secureiy tightening the bevei 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.

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