your miter saw works. Read this manual to understand this miter saw.
Safety Signal Words
DANGER: means if the safety infor-
mation is not followed someone will
be seriously injured or killed.
Before Using The Saw
WARNING: Some dust created by
power sa ndin g, s awi ng, gri ndi ng,
drilling, and other construction
activities contains chemicals
known (to the State of California)
to cause cancer, birth defects or
other rep r od uc ti v e harm. Some
examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks
and cement and other mason ry
products, and
• Arsenic and chromium from
chemically-treate d lumber.
Y o ur risk from these exposures
varies , depending on how often
you do th is 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 to filter
out microscopic particles.
WARNING: means if the safety infor-
mation is not followed someone
could be seriously injured or killed.

posi t ion s . Un pl ug t h e pow er c or d.
To reduce the risk of back injury, get
help when you need to lift the saw.
Never carry the tool by the cord or
power head trigger handle. Damage
to insulation could cause an electric
shock. Damage to wire connections
could cause a fire.
Reduce the Risk of Dangerous
Environment. Use the miter saw in a
dry, location, protected from rain.
Keep work area well lighted.
Place the saw so neither the user nor
bystanders are forced to stand in line
with the blade. Thrown debris could
injure people in its path.
To reduce the risk of injury from
unexpected saw movement:
• Pla ce the miter saw on a firm level
surface where there is plenty of
room for handling and properly sup-
porting the workpiece.
• Support the miter saw so the tabl e is
level and the saw does not rock.
• Bolt, screw or clamp the saw to its
support.
• Never Stand On To ol. Serious
injury could occur if the tool tips or
you accidentally hit the cutting tool.
Do not store anything above or near
the tool where anyone might stand
on the tool to reach them.
To reduce the risk of injury or
death from electrical shock:
• Make sure your fingers do not touch
the plug’s metal prongs when plugging or unplugging the miter saw.

order, and in proper adjustment.
Maintain Tools With Care. Keep the
miter saw clean for best and safest
performance. Follow instructions for
lubricating. DON’T put lubricants on
the blade while it’s spinning.
Remove Adjusting Keys And
Wrenches from tool before turning it
on.
To Reduce the Risk of Injury From Jams, Slips Or Thrown Pieces
• Use Only Recommended Accessories. (See “Accessory” section
within.) Consult this owner’s manual
for recommended accessories. Follow the instructions that come with
the accessories. The use of
improper accessories may cause
risk of injury to persons.
• Choose the right 12-inch diameter
blade for the saw and the material
you plan to cut.
• Mak e sure the blade is sharp,
undamaged and properl y aligned.
With the saw unplugged, push the
power head all the way down. Hand
spin the blade and check for clearance. Tilt the power head to 45
degrees left and right bevel and
repeat the check. If the blade hits
anything, make the adjustments
shown in “Alignment (Adjustments)”
section.
• Make sure the blade and arbor collars are clean.
• Make sure the collars' recessed
sides are facing the blade.
• Using the 1/4” hex end of combination wrench (supplied) or a 1/2-inch
box end wrench, make sure the left
hand thread arbor screw is firmly
tightened counterclockwise.
• Make sure all clamps and locks are
tight and there is no excessive play
in any parts.
• Keep Work Area Clean. Cluttered
areas and benches invite accidents.
Floor must not be slippery .
To reduce the risk of burns or other
fire damage, never use the saw near
flammable liquids, vapors or gases.
Plan Ahead To Protect Your Eyes, Hands, Face and Ears
Know Your Miter Saw. Read and
understand the owner ’s manual and
labels affixed to the tool. Learn its
applications and limitations as well as
the specific potential hazards peculiar
to this tool.
To reduce the risk of injury from accidental contact with moving parts,
don’t do layout, assembly, or setup
work on the miter saw while any parts
are moving.
To Reduce the Risk of Accidental
Starting. Make sure switch is “OFF”
before plugging miter saw into a
power outlet.
Plan your work.
Use The Right Tool. Don’t force tool
or attachment to do a job it was not
designed to do. Use a different tool
for any workpiece that can’t be held in
a solidly braced, fixed position.

Safety Instructions for Miter Saws (continued)
CAUTION: Because of the slid ing
action of this saw, this machine
is not designed for cutting metals. Use this miter saw to cut
only wood and wood like products. Other materials may shatter , bind on the blade, start fires
or create other dangers.
Dress F o r Safety
Any power tool can throw foreign
objects into the eyes. This can result
in permanent eye damage. Wear
safety goggles (not glasses) that
comply with ANSI Z87.1 (or in Canada CSA Z94.3-99) shown on package. Everyday eyeglas ses have only
impact resistant lenses. They are not
safety glasses. Safety goggles are
available at many local retail stores.
Glasses or goggles not in compliance
with ANSI or CSA could seriously hurt
you when they break.
Preparing to Make Cut
Do not wear loose clothing, gloves,
neckties or jewelry (rings, wrist
watches) They can get caught and
draw you into moving parts.
• Wear nonslip footwear.
• Tie back lon g ha ir.
• Roll long sleeves above the elbow.
• Noise levels vary widely. To reduce
the risk of possible hearing damage,
wear ear plugs or muffs when using
miter saw for hours at a time.
• For dusty operations, wear a dust
mask along with safety goggles.
Inspect Your Workpiece. Make sur e
there are no nails or foreign objects in
the part of the workpiece to be cut.
Plan your work to reduce the risk
of thrown pieces caused when the
workpiece binds on the blade and
is torn from your hands.
Plan how you will make the cut.
Always:
• Make sure the blade is not spinning.
• Raise the blade.
• Slide the saw out above the front
edge of the workpiece before starting saw, and
• Push the sawblade down on top of
the wood and back toward the rear
of the saw to make the cut.
DANGER: NEVER pull the saw
toward you during a cut. The
blade can sudden ly climb up on
top of the workpiece and force
itself toward you.
6
Plan The Way You Will Hold The Workpiece From Start To Finish.
• Avoid awkward operations and hand
positions where a sudden slip could
cause fingers or hand to move into
the blade.
• Don’t Overreach. Keep good footing and balance.
• Keep your face and body to one
side of sawblade, out of line with a
possible thrown piece.
• Cu t only one workpiece at a time.
• Never cut Freehand :
- Brace your workpiece solidly
against the fence and table top so
it will not rock or twist during the
cut.
-Make sure there’s no debris
between the workpiece and its
supports.
- Make sure no gaps between the
workpiece, fence and table will let
the workpiece shift after it is cut in
two.
• Keep the cut off piece free to move
sideways after it's cut off. Otherwise,
it could get wedged against the
blade and thrown violently.
• Clear everything except the workpiece and related support devices
off the table before turning the miter
saw on.
• Secu re Work . Use cl amps or a
vise to help hold the wor k wh en it’s
practical.
Use extra caution with large, very
small or awkward work pieces:
• Use extra supports (tables, saw
horses, blocks, etc.) for any workpieces large enough to tip when not
held down to the table top.
• Never use another person as a substitute for a table extension, or as
additional support for a workpiece
that is longer or wider than the basic
miter saw table or to help feed, support or pull the workpiece.
• Do n o t u s e th is saw to cut pieces
too small to let you easily hold the
work while you keep the thumb side
of your index (pointer) finger against
the outside edge of the fence.
• When cutting irregularly shaped
workpieces, plan your work so it will
not slip and pinch the blade and be
torn from your hands. A piece of
molding, for example, must lie flat
against the table or fence, or be held
by a fixture or jig that will not let it
twist, rock or slip while being cut.
• Properly support round material
such as dowel rods, or tubing. They
have a tendency to roll while being
cut, causing the blade to "bite." To
avoid this, always use a fixture
designed to properly hold your
workpiece.
Whenever Saw Is Running
WARNING: Don't al low familiarity
(gain ed f rom f requent use of
your miter saw) cause a careless
mistake. A careless fraction of a
second is enough to cause a
severe injury.
Before starting your cut, observe the
miter saw while it runs. If it makes an
unfamiliar noise or vibrates excessively , stop immediately. Turn the saw
off. Unplug the saw. Do not restart
until finding and correcting the problem.
Keep Children Away. Keep all visitors a safe distance from the miter
saw. Make sure bystanders are clear
of the miter saw and workpiece.
7
Safety Instructions for Miter Saws (continued)
Never confine the piece being cut
off. Never hold it, clamp it, touch it, or
use length stops against it while the
blade is spinning. It must be free to
move sideways on its own. If confined, it could get wedged against the
blade and be thrown violently.
Let the blade reach full speed
before cutting. T his will help avoid
thrown workpieces.
Don’t Force Tool. It will do the job
better and safer at its designed rate.
Feed the saw into the workpiece only
fast enough to let the blade cut without bogging down or binding.
Before Leaving The Saw
Never Leave Tool Running Unattended. Turn power off. Wait for all
moving parts to stop.
Make Workshop Child Proof. Install
a padlock through the hole provided
Before freeing jammed material:
• Turn miter saw “OFF” by releasing
trigger switch.
• Wait for all moving parts to stop.
• Unplug the miter saw.
After finishing a cut:
• Keep holding the power head down.
• Release the switch, and wait for all
moving parts to stop before moving
your hands or raising power head.
• If blade doesn’t stop within 6 seconds, unplug the saw and follow the
instructions in the Trouble Shooting
section for fixing the blade brake
before using the saw again.

6. Remove the arbor screw, arbor
washer, outer blade collar, and the
blade.
NOTE: Pay attention to pieces removed,
noting their pos ition and direction they
face (see illustration). Wipe the blade collars clean of any sawd ust bef ore inst all ing
the new blades.
CAUTION: To reduce the risk of
cuts from extremely sharp teeth:
Wear gloves when installing or
removing sawblade.
See cautions in “Using Carbide Tipped
Blades” section concerning inspection,
use, and selection of carbide tipped and
other sawblades.
7.Install the new 12" blade (see recommended accesso ry l ist). Make sure
the rotation arrow on the blade
matches the clockwise rotation arrow
on the upper guard. The blade teeth
should always point downward at the
front of the saw.
8.Instal l the outer blade collar, blade
washer and arbor screw. Press the
arbor lock and turn the combination
wrench or the 1/2" wrench counter
clockwise to sec ure the bl ade. Tighten
arbor screw usin g modera te force, but
do not overtighten.
9.Lower the lower blade guard until the
slot in cover plate rests all the way
down on the cover plate stop screw.
Tight en the scr ew with the Phi llip s en d
of the combination wrench.
DANGER: Never use saw without
guard cover plate securely in
place. It keeps the arbor screw
from falling out if it accidentally
loosens, and prevents the spinning blade from coming off the
machine.
10.Be sure the arbor lo ck is released so
the blade turns freely.

WARNI NG: Make sure the collars
are clean and properly arran ged .
After installing a new blade,
make sure the blade clears the
table slot at the 0° and 45° bevel
positions. Lower the blade into
the table slot and check for any
contact with the base or turn
table structure. If blade contacts
table, seek authorized service.
If blade contacts insert, refer to “Alignment“section for adjustme nt.

Assembling Dust Bag
1. Locate the dust bag fram e and cloth
dust bag.
2. Clip the dust bag frame in place on the
slide tubes as shown.
3. Slide the cloth dust bag over the dust
bag frame.
4. Connect the dust elbow t o the dus t port
on the upper blade guard.
5. Clamp dust bag onto elbo w.
NOTE: If connecting a 2-1/2" wet/dry vac
hose to the saw, do not attach the dust
bag frame, dust bag and elbow to the
saw. Connect the wet/dry vac hose
directly to the dust port on the upper blade
guard.
Workpiece Clamp Installation
The workpiec e clamp is used to help hold
the workpiece in the correct cutting position. It may be used on either the left side
of the miter saw or the right side. Before
turning the saw on make sure the workpiece clamp does not int erfere with the
cutting action of the saw.
1. Align pin in clamp shaft with keyway in
fence. In sert clamp shaft and rot ate.
Four Basic Saw Controls
In order to properly adjust and align the
Sliding Compound Miter Saw there are
four basic controls that must be understood.

To change the miter setting of the
blade:
a. Raise the miter lock lever .
b. Rotate the miter index wheel partial ly
downward to disengage the current
index and engage the next index.
c. Rotate the miter index wheel com-
pletely downward to bypass all mit er
indexes.
d. Turn the tabl e to the desired miter
setting and lock the miter lock lever.

2. B e vel lo c k le v e r/i n de x pin
To change the bevel setting of the
blade:
a. Pull the bevel lock lever for w ard.
Then rotate the bevel index pin
downward. This will allow the blade
to be tilted and at the same time “bypass” the preset bevel indexes.
b. To engage the pr eset bevel indexe s,
rotate the bevel lock index pin up.
c. Engage bevel index pin and/or bevel
lock lever before cutting.
3. Depth Adjustment Cam and Head Hold
Down
To release the blade -
a. While applying light downward pres-
sure on the handle, pull the depth
adjustment cam to th e right, then
raise the blade.
NOTE: It is not necessary to loosen
depth adjustment knob.
b. Rotate the depth adjustment cam so
the flat on the cam is facing upward.
NOTE: Head Hold Down is for transport and storage purposes only. No
cutting operations should take place
while hold down is engaged.
To lock the blade in the lower posit ion.
a. Pull the depth adjustment cam to the
right and lower the blade into the
table.
b. Rotate the depth adjustment cam
until slot engages pin on upper
guard.
4. Slide lock knob
Turn the slide lock knob counterclockwise to loosen and clock wis e to tight en.

WARNING: To reduce the risk of
injury from unexpected starting
or electrical shock, do not plug
the saw in. The power cord must
remai n un pl ug ged when ev er y ou
are working on the saw.
Step One: Repositioning Zero Clearance Blade Insert
The zero cleara nce blade insert needs to
be repositioned so it is temporarily out of
the way when aligning the blade. It may
be replaced after the blade is aligned.
1. Loosen the three screws that secure
the zero cle arance blade insert on one
side of the blade.
2. Slide the zero clearance insert away
from the blade as far as possi b l e .
3. Retighten the three screws.
4. Repeat steps 1-3 for the opposite side
of the blade.
Step Two: Slide T ube Adju stment
1. Plac e the powerhead in the 0° miter/ 0°
bevel index and lock head in lower position.
2. Check to see that the blade is approxi-
mately centered between the two zero
clearance blade inserts. Also check for
play between the rig ht slide rai l and the
pivot assembly.
3. If adjustment is required loos en the jam
nuts on all four gib screws as shown.
4. Loosen the top two gib screws.
5. Tighten or loosen the lower two gib
screws as required to center the blade
between the zero clearance inser ts.
6. Tighten the lower two jam nut s.
7. To minimize play in the slide tubes
gradually tighten the top t wo gib
screws while at t he sam e ti m e sli ding
the powerhead back and forth. Tighten
the top jam nuts.
