GENERAL SAFETY INSTRUCTIONS
BEFORE USING THIS POWER TOOL

Safety is a combination of common
sense, staying alert and knowing how
to use your power tool.

CAUTION
To avoid mistakes that could cause
serious injury, do not plug the tool in
until you have read and understood
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.

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.

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 one heavy enough to carry the
current your product will draw. An
undersized cord will result in a drop
in line voltage and in loss of power
which will cause the tool to overheat.
The table on page 11 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.

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.

POWER TOOL SAFETY

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.
NOTE: Glasses 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.

14.SECURE WORK. Use clamps or
a vise to hold work when
practical. It is safer than
using your hand and
it frees both hands to
operate the tool.

15.DISCONNECT TOOLS FROM

POWER SOURCE before servicing,
and when changing accessories
such as blades, bits and cutters.

16.REDUCE THE RISK OF

UNINTENTIONAL STARTING.
Make sure switch is in the OFF

Serious injury could occur if the
tool is tipped or if the cutting tool is
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.

20. NEVER LEAVE THE TOOL

RUNNING UNATTENDED. TURN
THE POWER “OFF”. Do not walk

away from a running tool until the

ELECTRICAL REQUIREMENTS AND SAFETY

ELECTRICAL REQUIREMENTS –
cont’d
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 fi t in a polarized outlet only one
way. If the plug does not fi t fully in the
outlet, reverse the plug. If it still does
not fi t, contact a qualifi ed 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 qualifi ed 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 circuit.
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.

2. If the motor will not 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.

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 fi nished.

4. FUSES may “blow” or circuit
breakers may trip frequently if:
a. MOTOR is overloaded –

overloading can occur if you feed

10

ELECTRICAL REQUIREMENTS AND SAFETY

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
specifi ed 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 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 qualifi ed
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.

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, fi xed position.

CAUTION: This machine is not
designed for cutting masonry,
masonry products, ferrous metals
(steel, iron, and iron-based metals.)
Use this miter saw to cut only
wood, wood-like products, or non­ferrous 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 fi re.
Remove dust bag when cutting non­ferrous metals.

29

OPERATION

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.

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 that are too small to
clamp and get a solid grasp on. Plan
the way you will grasp the workpiece
from start to fi nish. Avoid awkward
operations and hand positions. A
sudden slip could cause your fi ngers 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.

Never cut freehand:

● Brace your workpiece fi rmly 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
saws table.

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

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.

30

OPERATION

● Do not use this saw to cut small
pieces. If the workpiece being cut
would cause your hand or fi ngers
to be within 8-3/4 inches of the saw
blade the workpiece is too small.
Keep hands and fi ngers out of the
“no hands zone” area marked on the
saws table.

● 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 fl at or be held by a fi xture 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 specifi cally
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
fi nding and correcting the problem.

31

BODY AND HAND POSITION (FIG. U)

WARNING

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.

SLIDE CUTTING WIDE BOARDS UP
TO 12-1/4 in. WIDE (FIG. CC)

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. CC)

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

5. Engage the trigger to turn the saw
on.

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

7. Slowly move the switch handle
toward the fence, completing the cut.

8. Release the trigger and allow
the blade to stop spinning before
allowing the cutting head to raise.

CUTTING BOWED MATERIAL (FIG.
EE)

A bowed workpiece must be positioned

against the fence and secured with
a clamping devise before cutting as
shown. 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.

WORKPIECE SUPPORT AND
REPETITIVE CUTTING USING THE
STOP PLATE (FIG. DD)

Long pieces need extension table
support.

1. Loosen the knob (5) then slide the
extension table to desired position
and tighten the knob.

2. The stop plate is designed for use
during repetitive cutting. Only use

36

AUXILIARY WOOD FENCE (FIG. FF)

When making multiple or repetitive cuts
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.

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 18 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.

CUTTING BASE MOLDING (FIG. GG)

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
fi rmly against fence and table. Use
hold-down, crown molding vise
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. HH, II)

Your compound miter saw is suited
for the diffi cult task of cutting crown
molding. To fi t properly, crown molding
must be compound-mitered with
extreme accuracy. The two surfaces
on a piece of crown molding that fi t
fl at 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 fi ts fl at against
the ceiling) of 52°and a bottom rear
angle (the section that fi ts fl at 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 fl at 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.

WARNING

!

● To avoid fi re 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.

● For your safety, this saw is double

insulated. To avoid electrical
shock, fi re or injury, use only
parts identical to those identifi ed
in the parts list. Reassemble
exactly as the original assembly
to avoid electrical shock.

REPLACING CARBON BRUSHES
(FIG. JJ)

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, fi rst unplug the
saw. Then remove the black plastic
cap (1) on the side of the motor (2).
Carefully remove the spring-loaded
cap. Then pull out the brush and
replace. Replace for the other side. To
reassemble, reverse the procedure.

The ears on the metal end of the
assembly go in the same hole the
carbon part fi ts into. Tighten the cap
snugly, but do not overtighten.

NOTE: When reinstalling the same
brushes, put them back in the way they
came out. This will avoid a break-in
period that reduces motor performance
and increases wear.

LOWER 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.
Check regularly to make sure the lower
guard is working properly. Clean the
lower guard of any dust or buildup with
a damp cloth.

WARNING

!

● Do not use solvents on the guard.

They could make the plastic
“cloudy” and brittle.

● When cleaning the lower guard,

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

MAINTENANCE

SAWDUST

Periodically, sawdust will accumulate
under the worktable and base. This
could cause diffi culty in the movement
of the worktable 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.

LUBRICATION (FIG. KK)

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

Lubricate the following as necessary:

Link: (which actuates the lower guard
movement) may be oiled at the rear
pivot, greased at ball bearing contact,
and oiled where the link actuates the
acetyl roller of the lower guard, if the
down chop motion is hard to start.
