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, sa win g, g rin ding ,
drilling, and other construction
activities contains chemicals
known (to the State of California)
to cause cancer, birth defects or
other repr 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 masonry
products, and
• Arsenic and chromium from
chemically-treated lumber.
Yo ur 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 to filter
out microscopic particles.

When Installing Or Moving The Miter Saw
Before moving the saw, lock the
miter, bevel, slide and power head
posi ti on s. Unp lu g th e po wer cor 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, lo ca tion, 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:
• Place 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 Tool. 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.
• This TOOL IS DOUBLE INSULATED to give you added protection. Double insulation does not take
the place of normal safety precautions when operating this tool. When
servicing this double insulated tool,
use only identical parts.
Before Each Use
Inspect your miter saw.
Disconnect The Miter Saw. To
reduce the risk of injury from accidental starting, unplug the saw, before
changing the setup, changing the
blade or adjusting anything.
Compare the direction of rotation
arrow on the guard to the direction
arrow on the blade. The blade teeth
should always point downward at the
front of the saw.
Tighten the arbor screw.
Tighten the cover plate stop screw.
Check For Damaged Parts. Check
for:
• Proper Alignment of moving parts,
• Damaged electric cords,
• Binding of moving parts,
• Broken parts,
• Stable mounting,
• Function of arm return spring and
lower guard: Push the arm all the
way down, then let it rise up until it
stops by itself. Check the lower
guard to see if it closed fully. If it did
not, follow the instructions in the
“Troubleshooting” section.
• Smooth, solid movement of sliding
assembly.
• Other conditions that may affect the
way the miter saw works.

If any part of t his miter saw is missing,
bent, or broken in any way, or any
electrical parts don't work, turn the
saw off and unplug it. Replace damaged, missing, or failed parts before
using the saw again.
Keep Guards In Place, in working
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.
T o 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.
• Make sure the blade is sharp,
undamaged and properly 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, arbor collars
and laser system are clean.
• Make sure the arbor collars' and
laser discs’ recessed side s 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 Red uce 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 slidin g
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 Fo 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 eyeglasses 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.
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 long hair.
• 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.
Preparing to Make Cut
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 suddenly cli mb up on
top of the workpiece and force
itself toward you .
6
Page 7
Plan The Way You Will Hold The Work piece 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.
• Cut 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.
• Secure W o rk. Use clamps or a
vise to help hold the wor k wh en it’s
practical.
Use extra caution with large, very
small or awkward workpieces:
• 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 not u se thi s s a w to cut p i eces
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: Do n't al low famil iarity
(gained 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. T urn the saw
off. Unplug the saw. Do not restart
until finding and correcting the problem.
Keep Children Away. Ke ep all visitors a safe distance from the miter
saw. Make sure bystanders are clear
of the miter saw and workpiece.
7
Page 8
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. This 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.

and bevel knobs and lock the
power head in the lower position.
b. To reduce the risk of back
injur y, hold the tool clos e to
your body when lifting. Bend
your knees so you can lift with
your legs, not your back. Lift
by using the hand-hold areas
at each side of the bottom of
the base, by the carrying handle, or the handles on the front
of base.
c. Never carry the miter saw by
the power cord or the trigger
Place the saw in the desired location
either on a work bench or other recommended leg set. The base of the saw has
eight holes to mount the mit er saw. Four
smaller holes for screws are labeled A.
Four holes for bolts are labeled B (see
illustration) . If t he saw is to be used in o ne
location, permanent ly fas ten it to the work
bench or leg set.
NOTE: When mounted on a large flat surface, the miter saw table is 4-1/2” high.
Three stacked 2 x 4’ s can be used as a
work support extension.
Portable Applications
To mount the saw to a 3/4” piece of plywood, use 4, 1/4" bolt holes or
holes. The mounting board can then be
clamped down to prevent it from tipping.
Plywood mount also helps protect saw from
damage during the rough handling associated with portable miter saw usage.

Safety Instructions for Basic Saw Operations
Before Each Use
Inspect your saw.
Disconnect The Miter Saw. To
reduce the risk of injury from accidental starting, unplug the saw, before
changing the setup, changing the
blade or adjusting anything.
Compare the direction of rotation
arrow on the guard to the direction
arrow on the blade. The blade teeth
should always point downward at the
front of the saw.
Tighten the arbor screw.
Tighten the cover plate stop screw.
Check Damaged Parts. Check for:
• Proper alignment of moving parts,
• Damaged electric cords,
• Binding of moving parts,
• Broken parts,
• Stable mounting
• Function of arm return spring and
lower guard: Push the arm all the
way down, then let it rise up until it
stops by itself. Check the lower
guard to see if it closed fully. If it did
not, follow the instructions in the
“Troubleshooting” section.
• Smooth, solid movement of sliding
assembly.
• Other conditions that may affect the
way the miter saw works.
If any part of this miter saw if missing,
bent, or broken in any way, or any
electrical parts don’t work, turn the
saw off and unplug it. Replace damaged, missing, or failed parts before
using the saw again.
Keep Guards In Place, in work in g
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.
T o 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 material you
plan to cut.
• Make sure the blade is sharp,
undamaged and properly 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
degree bevel and repeat the check.
If the blade hits anything, make the
adjustments shown in the Maintaining “Alignment (Adjustments)” section.
• Make sure the blade, arbor collars
and laser system are clean.
• Make sure the arbor collars' and
laser discs’ recessed side s are facing the blade.
• Using 1/4” hex end of combination
wrench (supplied) or 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.
23
Page 24
Safety Instructions for Basic Saw Operations (con’t.)
• Keep work area clean. Cluttered
areas and benches invite accidents.
Floor must not be slippery.
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
application 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.
Reduce the Risk of Accidental
Starting. Make sure switch is “OFF”
before plugging miter saw into a
power outlet.
Dress Fo r Safety
The operation of any power miter saw
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 eyeglasses 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.
To reduce the risk of burns or other
fire damage, never use the miter saw
near flammable liquids, vapors or
gases.
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.
CAUTION: Because of the sliding action of this saw, this
machine is not designed for cutting metals. Use this miter saw
to cut only w ood , and wood like
products. Other materials may
shatter, bind on the blade, start
fires or create other dangers.
• Do not wear loose clothing, gloves,
necktie s or je w elr y ( rin gs , w ris t
watches) They can get caught and
draw you into moving parts.
• Wear nonslip footwear.
• Tie back long hair.
• 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.
24
Page 25
Preparing to Make the Cut
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 avoid 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 th e cut.
DANGER: NEVER pull the saw
toward yo u during a cut. The
blade can suddenly climb up on
top of t he workpiece and forc e
itself toward you.
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
poss ible th r o wba c k.
• Cut 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.
• Cut only one workpiece at a time.
• Keep the cut off piece free to move
sideways after it's cut off. Otherwise,
it could get wedged against the
blade and could be thrown violently.
• Clear everything except the workpiece and related support devises
off the table before turning the miter
saw on.
• Secure Work. Use clamps or a vise
to help hold the work when it’s practical.
Use extra caution with large, very
small or awkward workpieces:
• 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 not u se thi s s a w to cut p i eces
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 or
be held by a fixture or jig that will not
let it twist, roc k or s lip w h il e be in g
cut.
25
Page 26
Safety Instructions for Basic Saw Operations (con’t.)
• Properly support round material
such as dowel rods. They have a
tendency to roll while being cut,
Whenever Saw Is Running
causing the blade to "bite." To avoid
this, always use a fixture designed
to properly hold your workpiece.
WARNING: Do n't al low famil iarity
(gained 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. Tu rn 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.
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 thrown violently.
Let the blade reach full speed
before cutting. This will hel p reduce
the risk of a thrown workpiece.
Don’t Forc e 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 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.
Before Leaving The Saw:
Never Leave Tool Running Unattended.Turn power off. Wait for all
moving parts to stop.
Make workshop child-p roof. Install
a padlock through the hole provided
in the trigger to prevent unauthorized
usage. Lock the shop. Disconnect
master switches. Store tool away
from children and others not qualified
to use the tool.

Basic Saw Operations
Making Common Slide Compound
Cuts
There are two types of cuts that can be
made with the slide compound miter saw;
1.Slide Cutting
a. The slide lock knob is left loose, the
cutting head is pulled towards the
operator, the sawblade is lowered into
the workpiece and then pushed to the
rear of the saw to complete the cut.
b. Used for cutting wide pieces.
2.Chop Cutting
a. The slide lock knob is tightened and
the saw handle is pushed down to
cut through the workpiece.
b. This type of cut is used mainly for
narrow pieces.
Slide Cutting
Plan your work to avoid the spinning
blade and keep the workpiece from
binding on the blade and flying out of
your hands.
DANGER: Never pull the saw
toward yo u during a cut. The
blade can suddenly climb up on
top of t he workpiece and forc e
itself toward you.
DANGER: Never lower the saw
completely in front of the workpiece and then cut only on the
forward push. The upward moving re ar porti on of the blade
could twist the workpiece from
your grasp.
Workpieces up to 13-1/2” wide and 3-1/2”
thick can be cut following the directions
below:
1. Put wood against fence and secure
with clamp as appropriate.
2.Lo osen the slide lock knob.
3.Gr asp the saw handle and pull the car-
riage until the arbor (center of sawblade) is over the fr ont edge of the
workpiece.
4.Swit ch on the saw and allow t o come to
full speed.
WARNING: For your co nv enient
use, your saw has a blade brake.
The brake is not a safety device.
Never rely on it to replace proper
use of the guard on your saw. If
the blade does not stop within 6
seconds, unplug the saw and follow the instructions in the T r ou ble Shooting section for fixing
the brake before using saw
again.
WARNING: Do not try to cut
short pieces. You cannot properly support the workpiece and
keep your hold down hand the
required distance from the blade.
5.Push the saw handle all the way down
and cut through the leading edge of the
workpiece.
6.Gently push the saw handle towards
the fence completing the cut.
7.Push power head to full rear position
after each cut.
8.Turn motor off and allow blade to come
to a complete stop before moving hands.

Body and Hand Position
• Never place hands near cutting area.
Place hand at least 4" from path of
blade.
• Hold workpiece fir mly t o the fence to
prevent movement toward the blade.
• When holding the workpiece to the left
side of the blade, always use your left
hand. Use your right hand to hold the
workpiece to the right side of the blade.
• Before making a cut, make a “dry run”
with the power off so you can see the
path of the blade.
• Keep hands in position unt il trigger has
been released and the blade has completely stopped.
WARNING: Do not try to cut short
pieces, you cannot properly support the workp iece and
your hold down hand the

Compound Cut
When a compound cut is required, select
the desired bevel and miter positions.
Cutting C om pound Miters on
Picture Frames and Boxes
A compound miter is a cut requiring both
a miter setting and bevel setting. A compound miter i s used for making frames or
boxes that have sloping sides and are
wide at one end and narrow at the opposite end. Compound miter s are “tricky” to
make because the miter s etti ng and bevel
setting are direct ly related to each other.
Every time the miter sett ing is changed
the bevel setting mu st al so be adjusted;
likewise every adjustment to bevel
requires a corresponding adjustment to
miter . Beca use it may t ak e several trie s to
obtain the desired angle, it is advisable to
make test cuts on a scrap piece of m aterial.
Cutting Bowed Material
Before cutting a workpi ece, check to
make sure it is not bowed. If it is bowed
the workpiece must be pos itioned and cut
as illustrated. Do not position workpiece
incorrectly or try to cut the workpi ece with-
out the support of the fence. This will
cause pinchi ng of the workpiece on the
blade. The workpiece could suddenly
jump or mov e and your hand could hit the
blade.

workpieces. A void binding the
work agai n st the blade:
- Always hold or clamp your
work do wn to the saw.
- Do not hold or c la m p t he wo rk piece on both sides of the
blade. The blade can throw a
cut off piece if you confine the
workpiece on both sides of the
blade.
- Read and follow the instructions in the remainder of your
saw’s owners man ual.
- This accessory was designed
to make your miter saw operations more convenient. Read
and understand these instructions completely before use.
NOTE: The clamp can be used only in a
vertical position.
1. Place material to be cut on table of
miter saw. Secure workpiece to the
fence and table by turning knob to
tighten clamp. Do not overtighten the
clamp. It should just lightly hold the

2.Perform a dry run with the saw
unplugged. Af ter you believe that the
saw is complet ely s et up, pull the power
head down as if you were making an
actual cut. Check for interference s and
for potentiall y dangerous situations.
Adjust the set up so that a safe operation can be complete d.
3. Complete the cut as instructed in the
remainder of you miter saw owners
manual.
- Always perform dry runs. Make
sure the saw is unplugged.
Completely set up your saw.
Pull the blade and power head
through the full range of motion
to check for interference. The
clamp c an be used in a left or
right configuration. Make sure
that your blade, saw guard or
motor does not interfere with
the clamp. Correct any interference be fore use.
- Always tighten the clamp so
that the workpiece is secured
between the clamp and fence,
support or base. No visible gap
should be present between saw
and wood .
Workpiece
to be cut off
IMPORTANT: To help perform the safest
and most precise miter saw cut, make th e
cut and then release the power switch.
Hold the power head down and keep your
hands in place until the blade stops rotating. Then raise the power head and
remove workpiece from work table.

Basic Saw Operations (continued)
Workpiece Support
Long pieces need extra supports. The
supports shoul d be placed along the
workpiece so the wor kpiece does not sag
and your hand holding the workpi ece is
positioned 4” or mor e fro m the blade p at h.
The support should let the workpiece lay
flat on the base and work table during the
cutting operation.
NOTE: When mount ed on a large flat surface, the miter saw t able is 4-1/2” high.
Three stacked 2 x 4’s can be used as a
work support ext ension.
Auxiliary Fence
Certain unusual cuts may benefit from a
fence face extensi on due to the size and
position of the workpiece. Holes are provided in the fence to attach an auxiliary
fence. Get a straight piece of wood typically 1/2 inch t hick by 4 -1/4 i nches hig h by
23 inches long. To attach auxil iary fence,
place the piece of wood on the mite r saw
fence. Mark the hole locations from the
backside of the miter saw fe nce. Drill
.200”-.250” holes, then countersi nk the
holes on front of wood to receive #10 flat
head screws. Attach the auxiliary fence
securely and make a full depth cut. This
will create the blade sl ot. Check for interference between the auxiliary fence and
lower blade guard. Correct any interfer-
ence before proceeding. The auxiliary
fence is used with t he saw in the 0° bevel
position. If a bevel cut is desired, the auxiliary fen c e will hav e to be re m o v ed.

Rough C utt i ng A D ado
By using the depth adjustment cam it is
possible to rough cut a dado as shown.
On the outsi de of the depth adjustment
cam are a series of marks. Use these
marks as a refer ence to help s et the bl ade
to the correct cutting depth.
After the two outside cuts have been completed the inside material (represented
by slanted lines) is removed with a chisel.
To set the depth stop:
1. Position depth adjustment cam so it
engages locking col lar.
2. Loosen lock knob.
3. Position depth stop cam so the power-
head stops at the desired depth.
4.Cut the two outside grooves.
5.Use a wood chisel to remove the mate-
rial between the outside grooves.
6.To override depth setting pull depth
stop cam outward and rot ate so flat is
up.
NOTE: It is not neces sar y to l oosen dept h
adjustment knob.
NOTE: Because of the sawblades cutting
arc material at the beg inning or end of the
cut(s) may have to be removed with a
chisel.

Cutting Crown Moldings
Your compound miter saw does an excellent job of cutting crown molding. However, in order to fit properly, crown
molding must be cut with extreme accuracy.
Two Methods of Cutting Crown Molding
Crown molding may either be cut (1) flat
on the miter saw table or (2) ang led to the
table and fenc e. (See sq uare below) Most
standard (U.S.) crown m olding has a top
rear angle (angle that fits next to the ceiling) of 52° and a bottom rear an gle (angle
that fits against wall) of 38°. Your miter
saw has special mi ter s etti ngs at 31.6° lef t
and right and a bevel setti ng at 33.9° to
use when cutting crown molding flat on
the miter saw table. These settings are
identified with a “CM” mark.
Remember: Even though all of these
angles are standard, rooms are very
rarely constructed so the corners are
exactly 90°. You will need to “fine tune”
these settings and make necessary
adjustments to the cutting angle s.

Cutting Crown Molding Flat on the
Miter Saw Table
The advantage of cutting crown molding
flat on the table is that it is easier to
secure the molding at the correct cutti ng
position. Also larger pieces of crown
molding may be cut lay ing flat on the mite r
saw table.
1. Set the bevel and miter angles using
the chart belo w. Tighten the miter lo ck
knob and the bevel loc k knob.
2. Once again using the chart below cor-
rectly positions the molding.
3. Lower the head assembly, activate the
switch and make the cut. W ait until the
blade comes to a complete stop before
allowing the he ad as sembly t o ret urn to
the “UP” position and/or removing t he
workpiece.

Cutting Crown Molding Angled to the
Table and Fence
The advantage of cutt ing crown molding
in this position is that no bevel setting is
required. Small changes in the miter
angle can be made without affecting the
bevel angle. When using this method the
saw can be quickly and easi ly adjusted for
corners that are not 90° (square).
Making a crown molding support jig:
A crown molding support jig needs to be
constructed to help hol d the molding in
place during this cutting operation.
1.Ge t a s tr aig ht pi e ce o f wood t ypi c al ly 1/ 2
inch thick by 23-1/2 inches long (28
inches long if using the table extension)
and approximately 5 inches wide. The
actual width of this piece will depend on
overall width of the crown molding and
what the top and bottom angles are.
2.Dril l holes and temporarily m ount this
piece similar to building an Auxiliar y
Fence. However, do not cut the blade
slot at this time.
3.Pos it ion a piece of crown molding that
you are going to cut so the bott om part
(part whi ch is installed against the wall )
is against the wood fence. Make sure
the angles on the cro wn molding are
held firmly against the wood fence and
table of the miter saw. Mark the height
on the fence.
4.Remove the wood fence and cut to this
width.
5. Use small nail s an d glue t o att ach a top
piece (typic all y 1/2 inch thick by 1-1/ 2
inches wide by 23 inches long. Ma ke
sure the nails ar e no t locat ed bel ow the
sawblade.
6. Securely reattach the completed jig to
the miter saw fence and make a full
depth, 45° left and right miter cut.

DANGER: Never use the 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.
9.Be sure the arbor lock is released so
the blade turns freely .
NOTE: The arbor lock can be damaged
by improper use. If t he arbor lock will not
hold, lower the blade down on to a scrap
piece of wood positioned against the
fence. This will serve as an alternate locking means.

DANGER: Laser radiation. Avoid
direct eye exposure.
When the saw is “ON” and the blade is in
its highest position, the laser system will
show up on your workpiece as a red colored broken l ine. This red broken line will
assist you in l ining up the cut mark on the
workpiece with t he blade for accurate
cuts.
1.Position your wor kpiece on the saw.
Make sure the blade i s at its highest
position.
2.Turn the saw “ON” and a broken red
line will appear on your workpiece.
3.Align this red line with the cut-off mark
on the workpiece.
4.Lo wer th e sawblade and make the cut.
As the blade gets closer to the workpiece the broken red li ne wil l become
solid. Do not move the workpiece.
5.Turn the saw “OFF” and allow the
blade to come to a complete stop
before raising.
Practice cut s will let you become familiar
with correctly lining the laser mark up with
the cut-of f mark and blade.

DANGER: Never put lubricants
on the blade while it is spinning.
WARNING: To reduce the risk of
injury from unexpected starting
or electrical shock, unplug the
power cord before working on
the saw.
WARNING: For yo ur safety, this
saw is double insulated. To
avoid e lectrical s hock, f ire or
injury, use only parts identical to
those ide nti fied i n the parts lis t.
Reassemble exactly as original
assemb ly to avoid electrical
shock.
Replacing Carbon Brushes
The carbon brushes furnished will last
approximately 50 hours of running tim e or
10,000 on/off cycles. Replace both carbon
brushes when either has less than 1/4"
length of carbon remaining. To inspect or
replace brushes, first unplug the saw. Then
remov e the bl ac k p las t ic ca p o n th e s ide of
the motor (caution, this cap is spring
loaded by the brush assembly). Then pull
out th e b rus h . Re pe at f or t h e ot h er s id e. To
reassemble reverse the procedure. The
ears on the metal end of the brush assembly go in the same hole the carbon part fits
into. Tighten the cap snugly but do not
overtighten.
NOTE: To reinst all t he same brush es, fir st
make sure the br ushes go ba ck in t he way
they came out. Otherwise a break-in
period will occur that will reduce motor
performance and increase brush wear.
Lower Blade Guard
Do not use the saw without the lower
guard. The lower blade guard is attached
to the saw for your protection. Should the
lower guard become damaged, do not
use the saw until damaged guard has
been replac ed. Develop a regular check
to make sure the lower guard i s working
properly. Clean the lower guard of any
dust or build up with a damp cl oth.
CAUTION: Do not use solvents
on the guard. They could make
the plastic "cloudy" and brittle.
W ARNING: Wh en cleanin g lower
guard unplug the saw from the outlet to avo i d u n expected start-up.
Periodically, sawdust will accumulate
under the work tabl e and base. Thi s coul d
cause difficulty in the movem ent of the
work table when setting up a miter cut.
Frequently blow out or vacuum up the
sawdust.
WARNING: If blowing sawdust,
wear proper eye protection to
keep debris from blowing into
eyes.
