f) Keep cutting tools sharp and
clean. Properly maintained cutting
tools with sharp cutting edges are
less likely to bind and are easier to
control.
g) Use the power tool, accessories
and tool bits, etc. in accordance
with these instructions, taking
into account the working
conditions and the work to be
performed. Use of the power tool
for operations different from those
intended could result in a hazardous
situation.
5) SERVICE
a) Have your power tool serviced by
a qualified repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.
g) If devices are provided for the
connection of dust extraction and
collection facilities, ensure these
are connected and properly used.
Use of dust collection can reduce
dust-related hazards.

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 and
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.
•
•
PROPERLY SUPPORT LONG OR
WIDE WORKPIECES. Loss of control
of the workpiece can cause injury.
NEVER CROSS ARMS IN FRONT OF
BLADE while using tool. Always make
a dry run (unpowered) before making
a finish cut so that you can check the
path of the blade or severe personal
injury may result.
•
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,

•
MOTOR is overloaded – overloading
can occur if you feed too rapidly or
make too many start/stops in a short
time.
•
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.
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
•
•
To avoid injury, never use the saw
without the cover plate secure in
place. It keeps the arbor bolt from
falling out if it accidentally loosens,
and helps prevent the spinning blade
from coming off the saw. It also
keeps the guard from contacting a
spinning blade.
Make sure the collars are clean and
properly arranged. Lower the blade
into the table and check for any
contact with the metal base or the
turn table.

WARNING
TO ENSURE THE BLADE
This machine is not
designed for cutting masonry, masonry
products, metals. Use this miter saw to
cut only wood, or wood-like products.
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
non-ferrous metals.
PATH IS CLEAR OF OBSTRUCTIONS,
ALWAYS MAKE A DRY RUN OF THE
CUT WITHOUT POWER BEFORE
MAKING ANY CUTS ON THE
WORKPIECE.
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.
DRESS FOR SAFETY
Never cut freehand:
Any power tool can throw foreign

Brace your workpiece firmly against the
fence and table stop so it will not rock
or twist during the cut.
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.
•
•
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.
•
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.
•
•
Only the workpiece should be on the
saws table.
Secure work. Use clamps or a vise to
help hold the work when it is practical.
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.
USE EXTRA CAUTION WITH LARGE
OR ODD SHAPED WORKPIECES
•
•
Use extra supports (tables, sawhorses,
blocks, etc.) for workpieces large
enough to tip.
INSPECT YOUR WORKPIECE
Make sure there are no nails or foreign
objects in the part of the workpiece
being cut.
•
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.
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. Keep your hands at least
6 inches away from the blade path.
•
•
Do not use this saw to cut small pieces.
If the workpiece being cut would cause
your hand or fingers to be within 6 in.
of the saw blade the workpiece is too
small. Keep hands and fingers 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 flat or be
held by a fixture or jig that will not let it
move when cut.
A sudden slip could cause your fingers
or hand to move into the blade.
20
•
•
Properly support round material such
as dowel rods, or tubing, which have
a tendency to roll when cut, causing
the blade to “bite”. This is especially
important when making angle cuts.
NEVER tie, tape or hold the guard open
when operating the saw.
BODY AND HAND POSITION
(FIGURE R, S, T, U, V)
!
WARNING
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. Do not force the
saw. It will do the job better and safer at
its designed rate.
!
WARNING
A workpiece that is
clamped, balanced and secure before
a cut may become unbalanced after
a cut is completed. An unbalanced
load may tip the saw or anything the
saw is attached to, such as a table or
workbench. When making a cut that
may become unbalanced, properly
support the workpiece and ensure the
saw is firmly bolted to a stable surface.
Personal injury may occur.
ALWAYS MAKE DRY RUNS
(UNPOWERED) BEFORE FINISH CUTS
SO THAT YOU CAN CHECK THE PATH
OF THE BLADE. DO NOT CROSS
HANDS, AS SHOWN IN FIGURE R, S, T
& U.
!
WARNING
The clamp foot must
R
remain clamped above the base of
the saw whenever the clamp is used.
Always clamp the workpiece to the
base of the saw – not to any other part
of the work area. Ensure the clamp foot
is not clamped on the edge of the base
of the saw.

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°.
2-4/5 in.
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.
CUTTING BASE MOLDING
(FIGURE CC)
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:
When setting the bevel and miter angles
for compound miters, remember that the
settings are interdependent; changing
one changes the other, as well.
•
Always make sure moldings rest firmly
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.
Reduce splintering by taping the cut
area prior to making the cut. Mark the

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 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
exactly the way they came out. This will
avoid a break-in period that reduces motor
performance and increases wear.
MAINTENANCE
!
WARNING
•
To reduce the risk of injury, turn unit
off and disconnect it from power
source before installing and removing
accessories, before adjusting or
when making repairs. An accidental
start-up can cause injury.
•
DO NOT touch the sharp points on
the blade with fingers or hands while
performing any maintenance.
!
DANGER
FF
•
•
To avoid injury, never put lubricants
on the blade while it is spinning.
DO NOT use lubricants or cleaners
(particularly spray or aerosol) in
the vicinity of the plastic guard.
The plastic material used in the
guard is subject to attack by certain
chemicals.

!
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.
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.
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.
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 startup.
Do not use solvents on the guard.
They could make the plastic “cloudy”
and brittle.
REPLACING CARBON BRUSHES
(FIGURE FF)
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 plastic cap (1)
on the side of the motor (2). Remove the
cap cautiously, because it is springloaded.
Then pull out the brush and replace.
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.
28
To empty the dust bag, remove the
sawdust bag from the dust collection
port. Open the zipper on the sawdust
bag and empty out the sawdust inside.
Close the zipper and reinstall the dust
bag as described on page 13.
