and safer at the rate for which it was designed.
9. USE THE RIGHT TOOL. Do not force toot or
attachment to do a job for which it was not designed.
10.USE 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 wilt result in a drop in line voltage
and in loss of power which will cause .the tool to
overheat. The table on page 5 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.
! 1.WEAR PROPER APPAREL. Do not wear loose
clothing, gloves, neckties, rings, bracelets, or other
jewelry which may get caught in moving parts.

SPECIFICATIONS section on page 2.
universal,
PRODUCT
To avoid electrical hazards, fire hazards, or damage to
the tool, use proper circuit protection. Your saw is wired
at the factory for 120V operation. Connect to a I20V, !5
Amp circuit and use a 15 amp. 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.
DOUBLE INSULATED []
The power tool is double insulated to provide a double
thickness of insulation between you and the 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 iike
the one shown below:
il 'L2_2_i!r
I,q-h /
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.
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. This tool is intended for
indoor use only_
MOTOR SAFETY PROTECTION
IMPORTANT."
To avoid motor damage, the motor shoutd be blown out
or vacuumed frequently to keep sawdust from interfering
with the motor ventilation.
1. Connect this saw to a 120V, 15 amp. circuit with a 15
amp. 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.
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 !oads,
however, 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, tow 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 proper extension cord. Make sure your extensiorh
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 doubL 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. Atways 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 # 12 wire and should be
protected with a 15 Amp time delay fuse. 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.

e Remove adjusting wrench from the toot before
turning it on.
To avoid injury from jams, slips, or thrown
pieces:
USE ONLY RECOMMENDED ACCESSORIES
@Consult the ACCESSORIES and
ATTACHMENTS section of this Operator's
Manual for recommended accessories. Follow
the instructions that come with the accessory.
The use of improper accessories may cause
serious injury.
¢ Choose the correct 10 inch diameter blade for
the material and the type of cutting you plan to
do.
@Make sure the blade is sharp, undamaged and
properly aligned. With the saw unplugged, push
the cutting arm all the way down. Hand spin the
blade and check for clearance. Tilt the
power-head to a 45 ° bevel and repeat the check.
o Make sure the blade and arbor collars are clean.

To avoid burns or other fire damage, never use the
miter saw near flammable liquids, vapors, or gases.
o Plan ahead to protect your eyes, hands, face
and ears.
Know your miter saw.
Read and understand the Operator'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 avoid injury from accidental
contact with moving parts, don't do layout, assembly,
or setup work on the miter saw while any parts are
moving.
@ Avoid accidental starting
Make sure the switch is OFF before plugging the
miter saw into a power outlet.
PLAN YOUR WORK
Use the right toot. 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 solidiy braced, fixed position.
CAUTION: This machine is not designed for cutting
ferrous metals (steel, iron, and iron-based metals.)
Use this miter saw to cut only wood, wood-like
products, or soft metals like aluminum. 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.
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
cause serious injury when they break.
Do not wear loose clothing, gloves, neckties or
jewelry (rings, watches). They can get caught
and draw you into moving parts.
o Wear non-slip footwear.
o Tie back tong hair.
e Roll long sleeves above the elbow.
o 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 finish. Avoid awkward operations and hand
positions. A sudden slip could cause your fingers or
hand to move into the blade.
DON'T 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 firmly against the fence
and table stop so it will not rock or twist during
the cut.
e Make sure there is no debris between the
workpiece and the table or fence.
_:.iiiil i:!:i,_'! 17
e Make sure there are no gaps between the
workpiece, fence and table that will let the
workpiece shirt after it is cut.
e 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.
e Only the workpiece should be on the saw table.
e Secure work. Use clamps or a vise to help hold
the work when it's practical.
USE EXTRA CAUTION WITH LARGE OR ODD
SHAPED WORKPJECES.
¢ 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 6-1/2 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.
• 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 tet it
move when cut.
¢ Properly support round material such as dowel
rods, or tubing, which have a tendency to roll
when cut, causing the biade to "bite".
WHEN SAW IS RUNNING
Don't 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 OFR
Unplug the saw. Do not restart until finding and
correcting the problem.

CUTTING BOWED MATERIAL (FIG. U)
A bowed workpiece must be positioned and
cut. 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.U
WORK:PiECE SUPPORT (FIG, V)
Long pieces need extra support. The support
should be placed under the workpiece. Keep your
hand holding the workpiece positioned 6-1/2" or
more away from the blade, The support must let
the workpiece tay flat on the work table during the
cutting operation.
NOTE: When mounted on a flat surface, the miter
saw table is 3-13/16 inches high.

AUXtLARY WOOD FENCE (FIG. W)
When making multipte or repetitive cuts that result in
cut-off pieces of one inch or less, it is possible for the
saw blade to catch the cutooff 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 constructed of
straight auxiliary wood approximately 3/4 inch thick by
3 inches high by 19q12 inches 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 iVlOLD_NG (FIG, Z)
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 materiafto
achieve best results:
1. Always make sure moldings rest firmly against
fence and table. Use hold-down 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 cut. Mark cut line directly on the tape,
3. Splintering typically happens due to wrong blade
application and thinness of the material.

![](asset-c.png)
CUTTINGCROWNMOLDING (FIG. AA, BB, CC)
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. Also keep in
mind that the angles from crown molding are very easy
for these angles to shift slightly, all settings should be
tested on scrap molding.
Use crown molding hold-down clamp, whenever
possibIe, and place tape on the area being clamped to
avoid marks.

MAINTENANCE
DANGER
Never put lubricants on the blade while it is spinning.
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 3ower cord before working on the
saw.
For your safety, this saw is double-insulated 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. DD)
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 114" 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 isspringloaded. Then
pul! 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 slot
the carbon part fits into. Tigtlten the cap snugly, but
do not overtighten.
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 increase wear.
Fig.DD
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. Develop a regular check to make sure the
lower guard is working properly. C_ean the lower
guard of any dust or buildup with a damp cloth.
CAUTION: 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
startup.
SAWDUST
Periodically, sawdust will accumulate under the work
tabie 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.
If blowing sawdust, wear proper eye protection to
keep debris from blowing into eyes.
LUBRICATION
All the motor bearings in this tool are lubricated with a
sufficient amount of high grade Jubricant for the life of
the unit under normal operating conditions; therefore,
no further lubrication is required.
Lubricate the Following as Required:
Chop pivot: light machine oil or aerosol will penetrate
from the ends of the junction points. A qualified
service technician can remove the pivot bumper to
relieve tension, and the 2 metric set screws holding
the shaft, in order to drive the shaft about 3/4" right.
Exposed surfaces should be lubricated with
automotive type oil.
Central pivot of plastic guard: Use light household oil
(sewing machine oil) on metat4o-metal or
metal-to-plastic guard contact areas as required for
smooth, quiet operation. Avoid excessive oil, to which
sawdust will cling.
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 roller of
the lower guard, if the down chop motion is hard to
start.
