CALIFORNIA PROPOSITION 65

WARNING

!

Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contains chemicals known to the state of California to cause cancer, birth defects
or other reproductive harm. Some examples of these chemicals are:

● Lead from lead-based paints,

● Crystalline silica from bricks, 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 to
filter out microscopic particles. Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or
lay on the skin may promote absorption of harmful chemicals.

the following.

1. READ and become familiar
with the entire Operator’s
Manual. LEARN the tool’s

application, limitations and possible
hazards.

2. KEEP GUARDS IN PLACE and in

working order.

3. REMOVE ADJUSTING KEYS

AND WRENCHES. Form the habit
of checking to see that keys and
adjusting wrenches are removed
from the tool before turning ON.

4. KEEP WORK AREA CLEAN.

Cluttered areas and benches invite
accidents.

7. MAKE WORKSHOP CHILD
PROOF with padlocks, master
switches or by removing starter
keys.

8. DO NOT FORCE THE TOOL. It will
do the job better and safer at the
rate for which it was designed.

9. USE THE RIGHT TOOL. Do not
force the tool or an attachment
to do a job for which it was not
designed.

10. USE PROPER EXTENSION
CORDS. Make sure your extension
cord is in good condition. When
using an extension cord, be sure to
use the one heavy enough to carry
the current that the product will
draw. An undersized cord will result
in a drop in line voltage and in
loss of power which will cause the
tool overheat. The table on page
11 shows the proper wire gauge
size usage to each extension cord
length and ampere rating. If in
doubt, use the next heavier gauge.
The smaller the gauge number, the
heavier the cord.

5. DO NOT USE IN DANGEROUS
ENVIRONMENTS. Do not use
power tools in damp locations, or
expose them to rain or snow. Keep
work area well lit.

6. KEEP CHILDREN AWAY. All visitors
and bystanders should be kept a
safe distance from work area.

11. WEAR PROPER APPAREL. Do
not wear loose clothing, gloves,
neckties, rings, bracelets or other
jewelry which may get caught in
moving parts. Nonslip footwear is
recommended. Wear protective
hair covering to contain long hair.

12. ALWAYS WEAR EYE
PROTECTION. Any power
tool can throw foreign

objects into the eyes and could
cause permanent eye damage.
ALWAYS wear Safety Goggles (not
glasses) that comply with ANSI
Safety standard Z87.1. Everyday
eyeglasses have only impact–
resistant lenses. They ARE NOT
safety glasses. Safety Goggles are
available at Sears.

or goggles not in compliance with
ANSI Z87.1 could seriously injure
you when they break.

13. WEAR A FACE MASK
OR DUST MASK. Sawing
operation produces dust.

1 4 . SECURE WORK. Use

clamps or a vice to hold
work when practical. It is

safer than using your hand and
it frees both hands to operate
the tool.

unintentionally contacted.

19. CHECK FOR 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 should
be properly repaired or replaced.

15. DISCONNECT TOOLS FROM
POWER SOURCE before servicing,
and when changing accessories
such as blades, bits and cutters.

16. REDUCE THE RISK OF

COMPOUND MITER SAW SAFETY

SPECIFIC SAFETY INSTRUCTIONS
FOR THIS COMPOUND MITER SAW

1. DO NOT operate the miter saw
until it is completely assembled
and installed according to these
instructions.

2. IF YOU ARE NOT thoroughly
familiar with the operation of miter
saws, seek guidance from your
supervisor, instructor or other
qualified person.

3. ALWAYS hold the work firmly
against the fence and table.
DO NOT perform any operation
free hand (use clamp wherever
possible).

4. KEEP HANDS out of the path of
the saw blade. If the workpiece
you are cutting would cause your
hands to be within 7.5 in. of the

saw blade, the workpiece should
be clamped in place before making
the cut.

5. BE SURE the blade is sharp, runs
freely and is free of vibration.

10. USE only blade collars specified for
your saw.

11. NEVER use blades larger in
diameter than 10 inches.

12. NEVER apply lubricants to the
blade when it is running.

13. ALWAYS check the blade for
cracks or damage before operation.
Replace a cracked or damaged
blade immediately.

14. NEVER use blades recommended
for operation at less than 4800 RPM.

15. ALWAYS keep the blade guards in
place and use at all times.

16. NEVER reach around the saw blade.

17. MAKE SURE the blade is not
contacting the workpiece before the
switch is turned ON.

18. IMPORTANT: After completing the
cut, release the trigger and wait for
the blade to stop before returning
the saw to the raised position.

6. ALLOW the motor to come up to
full speed before starting a cut.

7. KEEP THE MOTOR AIR SLOTS
CLEAN and free of chips or dust.

8. ALWAYS MAKE SURE all handles
are tight before cutting, even if the
table is positioned in one of the
positive stops.

9. BE SURE both the blade and the
collar are clean and the arbor bolt
is tightened securely.

19. MAKE SURE the blade has come
to a complete stop before removing
or securing the workpiece,
changing the workpiece angle or
changing the angle of the blade.

20. NEVER cut metals or masonry
products with this tool. This miter
saw is designed for use on wood
and wood-like products.

8

21. NEVER cut small pieces. If the
workpiece being cut would cause
your hand or fingers to be within

7.5 in. of the saw blade the
workpiece is too small.

22. PROVIDE adequate support to the
sides of the saw table for long work
pieces.

immediately. Be alert at all times

- especially during repetitive,
monotonous operations. Don’t be
lulled into carelessness due to a
false sense of security. Blades
are extremely unforgiving. Clean
the lower guard frequently to help
visibility and movement. Unplug
before adjustment or cleaning.

23. NEVER use the miter saw in an
area with flammable liquids or
gases.

24. NEVER use solvents to clean
plastic parts. Solvents could
possibly dissolve or otherwise
damage the material.

25. SHUT OFF the power before
servicing or adjusting the tool.

26. DISCONNECT the saw from
the power source and clean the
machine when finished using.

27. MAKE SURE the work area is
clean before leaving the machine.

28. SHOULD any part of your miter saw
be missing, damaged, or fail in any
way, or any electrical component
fail to perform properly, lock the
switch and remove the plug from
the power supply outlet. Replace
missing, damaged, or failed parts
before resuming operation.

29. Because of the downward cutting
motion, your safety requires that
you stay very alert to keeping
hands and fingers away from the
path that the blade travels.

30. Be sure all guards are in place and
working. If a guard seems slow
to return to its normal position or
“hangs-up”, adjust or repair it

31. Abrasive cut-off wheels should
not be used on miter saws. Miter
saw guards are not appropriate for
abrasive cut-off wheels.

32. To avoid loss of control or placing
hands in the path of the blade,
hold or clamp all material securely
against the fence when cutting. Do
not perform operations freehand.

33. Support long material at the same
height as the saw table.

34. After completing a cut, release
the trigger switch and allow the
blade to come to a complete stop,
then raise the saw blade from the
workpiece.

35. Lock the miter saw head in the
down position during transport or
when not in use.

36. DRY RUN - It is important to know
where the blade will intersect
with the workpiece during cutting
operations. Always perform a
simulated cutting sequence with the
power tool switched OFF to gain an
understanding of the projected path
of the saw blade. At some extreme
angles, the right or left side fence
might have to be removed to
ensure proper clearance prior to
making a cut.

ELECTRICAL REQUIREMENTS AND SAFETY

POWER SUPPLY AND MOTOR
SPECIFICATIONS

The AC motor used in this saw is
a universal, nonreversible type.
See “MOTOR” in the “PRODUCT
SPECIFICATIONS” section on page 3.

WARNING

!

To avoid electrical hazards, fire
hazards, or damage to the tool, use
proper circuit protection. Your saw
is wired at the factory for 120 V
operation. Connect to a 120 V,
15 A circuit and use a 15 A time
delay fuse or circuit breaker. To
avoid shock or fire, if power cord is
worn or cut, or damaged in any way,
have it replaced immediately.

ELECTRICAL REQUIREMENTS –
DOUBLE INSULATED

The power tool is double insulated to
provide a double thickness of insulation
between you and tool’s electrical
system. All exposed metal parts are
isolated from the internal metal motor
components with protecting insulation.

Replacement parts – When servicing
use only identical replacement parts.

Polarized plugs – This saw has a plug
that looks like the one shown below:

To reduce the risk of electrical shock,
this saw has a polarized plug (one
blade is wider than the other). This plug
will fit in a polarized outlet only one
way. If the 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.

WARNING

!

Double insulation does not take the
place of normal safety precautions
when operating this tool.
To avoid electrocution:

1. Use only identical replacement

parts when servicing a tool with
double insulation. Servicing
should be performed by a
qualified technician.

2. Do not use power tools in wet or

damp locations or expose them
to rain or snow.

MOTOR SAFETY PROTECTION

IMPORTANT:

To avoid motor damage, the motor
should be blown out or vacuumed
frequently to keep sawdust from
interfering with the motor ventilation.

1. CONNECT this saw to a 120 V, 15 A

circuit with a 15 A time-delay fuse or
circuit breaker. Using the wrong size
fuse can damage the motor.

2. If the motor won’t start, release the

trigger switch immediately. UNPLUG
THE SAW. Check the saw blade to
make sure it turns freely. If the blade
is free, try to start the saw again. If
the motor still does not start, refer to
the TROUBLESHOOTING GUIDE.

10

3. If the tool suddenly stalls while
cutting wood, release the trigger
switch, unplug the tool, and free the
blade from the wood. The saw may
now be started and the cut finished.

4. FUSES may “blow” or circuit
breakers may trip frequently if:

a. MOTOR is overloaded –
overloading can occur if you feed
too rapidly or make too many
start/stops in a short time.
b. LINE VOLTAGE is more than
10% above or below the
nameplate voltage rating. For
heavy loads, the voltage at
motor terminals must equal the

voltage specified on the nameplate.
c. IMPROPER or dull saw blades
are used.

5. Most motor troubles may be traced

to loose or incorrect connections,
overload, low voltage or inadequate
power supply wiring. Always check
the connections, the load and
supply circuit if the motor doesn’t
run well. Check minimum gauge for
the length of cord you are using on
the chart below.

GUIDELINES FOR EXTENSION
CORDS

Use a 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 cause overheating. The
table below shows the correct size
to use depending on cord length and
nameplate ampere rating. If in doubt,
use the next heavier gauge. The
smaller the gauge number, the heavier
the cord.

Be sure your extension cord is
properly wired and in good condition.

Always replace a damaged extension
cord or have it repaired by a qualified
person before using it. Protect your
extension cords from sharp objects,
excessive heat and damp or wet areas.

Use a separate electrical circuit for
your tools. This circuit must not be less

than a #12 wire with a 20 A time-lag
fuse or a #14 wire with a 15 A time-lag
fuse. NOTE: When using an extension
cord on a circuit with a # 14 wire, the
extension cord must not exceed 25 feet
in length. Before connecting the tool to
the power line, make sure the switch
is in the OFF position and the electric
current is rated the same as the current
stamped on the motor nameplate,
running at a lower voltage will damage
the motor.

●

Read warnings and conditions on
your CARBIDE TIPPED SAW BLADE.
Do not operate the saw without the
proper saw blade guard in place.
Carbide is a very hard but brittle
material. Care should be taken while
mounting, using, and storing carbide
tipped blades to prevent accidental
damage. Slight shocks, such as
striking the tip while handling, can
seriously damage the blade. Foreign
objects in the workpiece, such as
wire or nails, can also cause tips
to crack or break off. Before using,

always visually examine the blade
and tips for bent blade, cracks,
breakage, missing or loose tips, or
other damage. Do not use if damage
is suspected. Failure to heed safety
instructions and warnings can
result in serious bodily injury.

BLADE INFORMATION

● Always use a crosscut blade that is
designed for cutting across the wood
grain. NEVER use Rip, Combination,
Plywood, Dado or Abrasive type saw
blades at any time

● Always use a 10 in. diameter blade with
either a 5/8” arbor hole, speed rating
must be at least 4800 RPM.

● Read and understand all instructions
provided with each blade before using
on this miter saw.

There are two main materials used for
saw blades; high-speed steel (HSS) and
carbide tipped (TCT). While the HSS
blades are generally less expensive
than carbide tipped, TCT blades will
stay sharper longer than HSS. As a
general rule the more teeth per inch (TPI)
the smoother the cut. Please read the
information provided on the blade for
more details for their use.

General Purpose Wood Cutting: 24 - 40 TPI
Fine Woodworking Cutting: 60 - 80 TPI
Non-ferrous Metal Cutting:

Use only special blades designed for
cutting this type of material.

Plastic Cutting:

Use only special blades designed for
cutting plastic.

NOTE: When cutting non-ferrous or
plastic, be sure to clean up completely
after each use. Take special care with
metal shavings after each cut, these can
cause damage to the table top. ALWAYS
WEAR EYE PROTECTION.

misplacing the blade wrench.

WOODWORKING TERMS

ARBOR – The shaft on which a blade

is mounted.

BEVEL CUT – An angle cut made
through the face of the workpiece.

COMPOUND CUT – An angled cut
to both the edge and face of a board,
most common use is with crown
molding.

CROSS CUT – A cut which runs across
the board perpendicular to the grain.

FREEHAND – Performing a cut without
using a fence (guide), hold down or
other proper device to prevent the
workpiece from twisting during the
cutting operation.

KICKBACK – sudden and unintended
movement of the tool or workpiece. It is
typically caused by binding or pinching
of the workpiece.

MITER CUT – A miter is a type of joint
where the two parts to be joined are cut
at an angle, and typically the finished
joint forms a 90-degree angle. Also
commonly spelled “mitre”.

REVOLUTIONS PER MINUTE (RPM)
– The number of turns completed by a
spinning object in one minute.

SAW BLADE PATH – The area of the
workpiece or table top directly in line
with the travel of the blade or the part
of the workpiece which will be cut.

SET – The distance between two saw
blade tips, bent outward in opposite
directions to each other. The further
apart the tips are, the greater the set.

THIN-KERF BLADE – Thinner than
normal blades, remove less material,
smaller kerfs (between 0.065 in. and

0.070 in.). Blade thinness also may
increase the heat generated while
cutting.

WORKPIECE – The wood being
cut. The surfaces of a workpiece are
commonly referred to as faces, ends
and edges.

HEEL – Misalignment of the blade.

KERF – The width of a saw cut,

determined by the thickness and set of
the blade.

accidents.

WARNING

!



To avoid burns or other fire damage,
never use the miter saw near
flammable liquids, vapors, or gases.

● Plan ahead to protect your eyes,
hands, face and ears.

● Know your miter saw. Read and
understand this Operator’s Manual
and labels affixed to this tool. Learn
its application and limitations as well
as the specific potential hazards
peculiar to this tool. To avoid injury
from accidental contact with moving
parts, do not do layout, assembly, or
setup work on the miter saw while
any parts are moving.

● Avoid accidental starting, make sure
the trigger switch is disengaged
before plugging the miter saw into a
power outlet.

PLAN YOUR WORK

● Use the right tool. Don’t force a 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

!



This machine is not designed for
cutting masonry, masonry products,
ferrous metals (steel, iron, and iron­based metals.) Use this miter saw to
cut only wood, wood-like products,
or non-ferrous metals. Other material
may shatter, bind the blade, or create
other dangers. Remove all nails that
may be in the workpiece to prevent
sparking that could cause a fire.
Remove dust bag when cutting non­ferrous metals.

32

DRESS FOR SAFETY

Any power tool can throw
foreign objects into the eyes.

This can result in permanent eye
damage. Everyday eyeglasses have
only impact resistant lenses and are not
safety glasses. Glasses or goggles not
in compliance with ANSI Z87.1 could
seriously injure you when they break.

● Do not wear loose clothing, gloves,

neckties or jewelry (rings, watches).
They can get caught and draw you
into moving parts.

● Wear non-slip footwear.

● Tie back long hair.

● Roll long sleeves above the elbow.

● Noise levels vary widely. To avoid

possible hearing damage, wear ear
plugs when using any miter saw.

● For dusty operations, wear a dust

mask along with safety goggles.

Never cut freehand:

● Brace your workpiece firmly against
the fence and table stop so it will
not rock or twist during the cut.

● Make sure there is no debris
between the workpiece and the
table or fence.

● Make sure there are no gaps
between the workpiece, fence and
table that will let the workpiece shift
after it is cut.

● Keep the cut off piece free to
move sideways after it is cut off.
Otherwise, it could get wedged
against the blade and thrown
violently.

● Only the workpiece should be on
the saw table.

● Secure work. Use clamps or a vice
to help hold the work when it’s
practical.

INSPECT YOUR WORKPIECE

● Make sure there are no nails or
foreign objects in the part of the
workpiece being cut.

● Plan your work to avoid small pieces
that may bind or are too small to
clamp and hold securely.

● Plan the way you will grasp the
workpiece from start to finish. Avoid
awkward operations and hand
positions. A sudden slip could cause
your fingers or hand to move into
the blade.

DO NOT OVER-REACH

Keep good footing and balance. Keep
your face and body to one side, out of
the line of a possible kickback. NEVER
stand in the line of the blade.

USE EXTRA CAUTION WITH LARGE
OR ODD SHAPED WORKPIECES.

● Use extra supports (tables,
sawhorses, blocks, etc.) for
workpieces large enough to tip.

● Never use another person as a
substitute for a table extension, or as
an 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 use this saw to cut small
pieces. If the workpiece being cut
would cause your hand or fingers
to be within 7.5 inches of the saw
blade the workpiece is too small.
Keep hands and fingers out of the
“no hands zone” area marked on
the saw table.

33

● When cutting odd shaped
workpieces, plan your work so
it will not bind in the blade and
cause possible injury. Molding, for
example, must lie flat or be held by
a fixture or jig that will not let it move
when cut.

● Properly support round material
such as dowel rods, or tubing, which
have a tendency to roll when cut,
causing the blade to “bite”.

WARNING

!

To avoid injury, follow all applicable
safety instructions, when cutting
non-ferrous metals:

● Use only saw blades specifically
recommended for non-ferrous metal
cutting.

● Do not cut metal workpieces
that must be hand held. Clamp
workpieces securely.

● Cut non-ferrous metals only if you
are under the supervision of an
experienced person and the dust bag
has been removed from the saw.

WHEN SAW IS RUNNING

WARNING

!

Do not allow familiarity from
frequent use of your miter saw
to result in a careless mistake.
A careless fraction of a second is
enough to cause a severe injury.

Before cutting, if the saw makes an
unfamiliar noise or vibrates, stop
immediately. Turn the saw OFF.
Unplug the saw. Do not restart until
finding and correcting the problem.

MAKING A BASIC CUT

WARNING

!

Body and Hand Position (Fig. BB)

Never place hands near
the cutting area. Proper

positioning of your body and
hands when operating the miter
saw will make cutting easier and
safer. Keep children away. Keep all
visitors at a safe distance from the
miter saw. Make sure bystanders
are clear of the saw and workpiece.
Don’t force the saw. It will do the job
better and safer at its designed rate.

Starting a cut:

● Place hands at least 7.5 in. away

from the path of the blade – out of
the “no-hands zone” (see (1) in

Fig. BB on next page).

● Hold workpiece firmly against the

fence to prevent movement toward
the blade.
Turn the laser guide on for pre-

●

alignment of your cut.

● With the power switch OFF, bring the

saw blade down to the workpiece to
see the cutting path of the blade.

● Squeeze trigger switch to start saw.

● Lower blade into workpiece with a

firm downward motion.

Finishing a cut:

● Hold the cutting arm in the down

position.

● Release trigger switch and wait

for all moving parts to stop before
moving your hands and raising the
cutting arm.

34

● If the blade doesn’t stop within

6 seconds, unplug the saw and
follow the instructions in

TROUBLESHOOTING GUIDE section.

Before freeing jammed material:

● Release trigger switch.

● Wait for all moving parts to stop.

● Unplug the miter saw.

BEVEL CUT (FIG. JJ)

WARNING

!

● The sliding fence must be
extended to the left when making
bevel cuts. The sliding fences note
three bevel angles where the user
must adjust the fences to match
the degree of the bevel cut. Failure
to extend the sliding fence will not
allow enough space for the blade
to pass through which could result
in serious injury. At extreme miter
or bevel angles the saw blade may
also contact the fence.

● The right side sliding fence must
be removed when making any
right bevel angle cuts greater
than 35° in combination with any
right hand miter angle. This fence
must also be removed whenever

bevel angle is desired with a

a 45°
miter angle greater than 22.5°.

1. When a bevel cut is required,
loosen the bevel locking handle (1)
by turning it clockwise.

2. Tilt the cutting head to the desired
angle, as shown on the bevel
scale (2).

SLIDE CUTTING WIDE BOARDS UP
TO 12-1/2 IN. WIDE (FIG. MM)

WARNING

!

To avoid injury:

● Never pull the cutting head
assembly and spinning blade
toward you during the cut. The
blade may try to climb up on the
top of the workpiece, causing the
cutting assembly and spinning
blade to kick back, forcefully. The
cutting head assembly should be
drawn back completely then pushed
forward when sawing.

● Let the blade reach full speed
before cutting. This will help reduce
the risk of a thrown workpiece.

To Slide Cut Wide Boards (Fig. MM)

1. Unlock the sliding carriage lock
knob (1) and allow the cutting head
assembly to move freely.

2. Set both the desired bevel angle
and/or the miter angle and lock into
position.

3. Use a hold-down clamp to secure
the workpiece.

4. Turn the laser guide on and position
the workpiece on the table for pre­alignment of your cut.

5. Grasp the trigger switch handle (2)
and pull the carriage (3) forward
until the center of the saw blade is
over the front of the workpiece (4).

6. Engage the trigger to turn the

saw on.

7. When the saw reaches full speed,
slowly push the saw handle down,
cutting through the leading edge of
the workpiece.

8. Slowly move the trigger switch
handle back toward the fence,
completing the cut.

9. Release the trigger and allow the
blade to stop spinning before raising
the cutting head and removing the
workpiece.

CUTTING BOWED MATERIAL
(FIG. NN)

WARNING

!

To avoid injury from materials being
thrown, always unplug the saw
to avoid accidental starting and
remove small pieces of material
from the table cavity underlying the
table insert.

The table insert may be removed for
this purpose, but always reattach table
insert prior to performing a cutting
operation. A bowed workpiece (1) must
be positioned against the fence and
secured with a hold-down clamp (2) as
shown before cutting. Do not position
workpiece incorrectly or try to cut the
workpiece without the support of the
fence. This will cause the blade to bind
and could result in personal injury.

Fig. NN

CUTTING GROOVES (FIG. OO)

WARNING

!

DO NOT USE A DADO BLADE, use
only the standard 10 in. diameter saw
blade for this operation.

1. Mark lines identifying the width
and depth of the desired cut on
the workpiece and position on the
table so the outside tip of the blade
is positioned on the inside edge of
the line. Use a clamp to secure the
workpiece beside the blade.

2. Lower the cutting head to the depth
marked on the workpiece, holding
the upper arm, and adjust the stop
knob (1) until it touches the stop
plate (2). (SEE “Setting the cutting
depth” on page 27).

3. Cut two parallel grooves as shown.

that result in cut-off pieces of one inch
or less, it is possible for the saw blade
to catch the cut-off piece and throw
it out of the saw or into the blade
guard and housing, possibly causing
damage or injury. To minimize this, an
auxiliary wood fence can be mounted
to your saw.

41

Holes are provided in the saw fence
to attach an auxiliary wood fence. This
fence is to be constructed of straight
wood approximately 3/4 in. thick by
2-1/2 in. high by 22 in. long.

Attach the wood fence securely and
make a full depth cut to make a
blade slot.

Check for interference between the
wood fence and the lower blade guard.
Adjust if necessary.

NOTE: This auxiliary fence is used
only with the saw blade in the 0° bevel
position (90° to the table). The auxiliary
wood fence must be removed when
bevel cutting.

Fig. PP

CUTTING BASE MOLDING (FIG. QQ)

Base moldings and many other
moldings can be cut on a compound
miter saw. The setup of the saw
depends on molding characteristics
and application, as shown. Perform
practice cuts on scrap material to
achieve best results:

1. Always make sure moldings rest
firmly against fence and table. Use
hold-down, crown molding vice
or C-clamps, whenever possible,
and place tape on the area being
clamped to avoid marks.

2. Reduce splintering by taping the cut
area prior to making the cut. Mark
the cut line directly on the tape.

3. Splintering typically happens due to
an incorrect blade application and
thinness of the material.

CUTTING CROWN MOLDING
(FIG. RR, SS)

Your compound miter saw is suited
for the difficult task of cutting crown
molding. To fit properly, crown molding
must be compound-mitered with
extreme accuracy. The two surfaces
on a piece of crown molding that fit
flat against the ceiling and wall are at
angles that, when added together,

equal exactly 90°.

Most crown molding 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°.

In order to accurately cut crown molding
for a 90° inside or outside corner, lay the
molding with its broad back surface flat
on the saw table.

When setting the bevel and miter angles
for compound miters, remember that the
settings are interdependent; changing
one changes the other, as well.

!

DANGER

To avoid injury, never put lubricants
on the blade while it is spinning.

!

WARNING

●

To avoid fire or toxic reaction,
never use gasoline, naphtha
acetone, lacquer thinner or
similar highly volatile solvents to
clean the miter saw.

● To avoid injury from unexpected

starting or electrical shock,
unplug the power cord before
working on the saw.

●

To avoid electrical shock, fire or
injury, use only parts identical
to those identified in the parts
list. Reassemble exactly as
the original assembly to avoid
electrical shock.

REPLACING CARBON BRUSHES
(FIG. TT)

The carbon brushes furnished will last
approximately 50 hours of running time,
or 10,000 ON/OFF cycles. Replace both
carbon brushes when either has less
than 1/4 in. length of carbon remaining,
or if the spring or wire is damaged or
burned. To inspect or replace brushes,
first unplug the saw. Then remove the
black plastic cap (1) on the side of the
motor (2). Remove the cap cautiously,
because it is springloaded. Then pull
out the carbon brush (3) and replace. To
reassemble, reverse the procedure. The
ears on the metal end of the assembly
go in the same hole the carbon part fits

into. Tighten the cap snugly, but do not
overtighten. Repeat for the carbon brush
located on the other side of motor.
NOTE: To reinstall the same brushes,
first make sure the brushes go back in
the way they came out. This will avoid
a break-in period that reduces motor
performance and increases wear.

Fig. TT

LOWERING BLADE GUARD

Do not use the saw without the lower
blade 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 the
damaged guard has been replaced.
Regularly check to make sure the lower
guard is working properly. Also check
before each use that all bolt/screws are
tight. Clean the lower guard of any dust
or buildup with a damp cloth.

!

WARNING

When cleaning the lower guard,

●

unplug the saw from the power
source receptacle to avoid
unexpected start-up.

● Do not use solvents on the guard.

They could make the plastic
“cloudy” and brittle.

SAWDUST

Periodically, sawdust will accumulate
under the work table and base. This
could cause difficulty in the movement
of the worktable when setting up
a miter cut. Frequently blow out or
vacuum up the sawdust.

Central pivot of plastic guard: Use light
household oil (sewing machine oil) on
metal-to-metal or metal-to-plastic guard
contact areas as required for smooth,
quiet operation. Avoid excessive oil, to
which sawdust will cling.

Fig. UU

If need to remove small pieces of
material from the table cavity, see the
section on Removing and Installing the
Table Insert on page 21.

To empty the dust bag, remove the
sawdust bag from the dust port. Open
the zipper on the sawdust bag and
empty out the sawdust inside. Close
the zipper and reinstall the dust bag on
the dust port as described on page 18.

!

WARNING

Wear proper eye protection to keep
debris from entering eyes when
removing sawdust from unit.

LUBRICATION (FIG. UU)

All the motor bearings in this tool are
lubricated with a sufficient amount of
high grade lubricant for the life of the
unit under normal operating conditions;
therefore, no further lubrication
is required.

Central pivot of
plastic guard (oil here)

Chop Pivot (oil here
and on opposite side)

Lubricate the following as necessary:

Chop pivot: Apply light machine oil to
points indicated in illustration.
