WHEN INSTALLING OR MOVING
THE SAW:
1, To avoid injury from unexpected saw movement'.
A. Place the saw on a firm level surface where
there is plenty of room for handling and
properly supporting the workplace.
B. Support the saw so the table is level and the
saw does not rock.
C. Bolt or clamp the saw to its support,
2, Before moving the saw, lock the miter, bevel
and power-head positions. Unplug electric cord.
3, To avoid back injury, get help when you need to
lift the saw more than 10 inches. Hold the tool
close to your body. Bend your knees so you can
lift with your legs, not your back. Lilt by using
the hand-hold areas at the bottom of the base.
Never carry the tool by the cord or power head
handle. Damage to insulation could cause an
electric shock. Damage to wire connections
could cause a fire.
BEFORE EACH USE:
1. Inspect your saw. If any part of this miter saw is
missing, or bent, or has failed in any way, or
any electrical parts don't work properly, turn the
saw off and unplug the saw. Replace damaged,
missing, or failed parts before using the saw
again.
2. Plan Your Work to protect your eyes, hands,
face, and ears.
A. Wear safety goggles (not glasses) that
comply with ANStZ87,1(shown on package).
Using any power tool can result in foreign
objects being thrown into the eyes, which
can result in permanent eye damage. Safety
goggles are available at stores. Use of
glasses or use of goggles not in compliance
with ANSiZ87.1 could result in severe injury
from breakage of the eye protection.
WEAR YOUR
B. For dusty operations, wear a face shield
along with safety goggles.
C. To avoid injury from jams, slips or thrown
pieces:
@Choose the right 10-inch diameter blade for
the material and the type of cutting you
ptan to do. Use this miter saw to cut only
wood, wood-like products or soft metals
like aluminum. Other materials may sha-
tter, grab at the blade, or create other
dangers.
eMake sure the direction of rotation arrow
on the blade matches the direction arrow
on the saw. The blade teeth should always
point downward at the front of the saw.
eMake sure the blade is sharp, undamaged
and properly aligned. With the saw un-
plugged, 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 Maximum Cutting Capacity
section,
eMake sure the blade and arbor collars are
clean.
• Make sure the collars' recessed sides are
facing toward the blade.
eMake sure the recessed side of the blade
washer (just under the arbor screw head)
faces the collar.
eUsing 1/2-inch box end wrench, make sure
the arbor cap screw retaining the blade
collars is firmly hand tightened.
eMake sure all clamps and locks are tight
and there is no excessive play in any parts.
• Never cut FREEHAND:
a. Brace your workplace solidly against the
fence and table top so it will not rock or
twist during the cut. Make sure no
debris is caught beneath_the workpiece.
b. Make sure no gaps between the work-
piece, fence and table will let the
workpiece shift after it is cut in two.
co Use jigs, fixtures or a different tool for
unstable workpieces.
3
• Never cut more than one workplace at a time.
• Make sure the cut off piece C_n move
sideways after it's cut off. Otherwise, it could
get wedged against the blade and thrown
violently. .............._ ,_;_
blocks, etc,)for any workpieces large enou-
gh to tip when not held down to the tabte
top.
b. Do not use this saw to cut pieces too small
to let you easily hold the work while you
keep the thumb side of your index (poi-
nter) finger against the outside edge of the
fence.
c. When cutting irregularly shaped work*
pieces, plan your work so it will not slip
and pinch the blade. A piece of motding,
for example, must lie flat or be held by a
fixture or jig that will not let it twist, rock
or slip while being cut.
d. 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 work piece.
• Make sure there are no nails or foreign
objects in the part of the workpiece to be cut.
• Make sure bystanders are clear of the tool and
workpiece. Keep them clear of the area behind
the saw where debris will be thrown.
• Never turn your miter saw _ON_ before
clearing everything except the workpiece and
related support devices off the table.
D. To avoid risk of hearing damage, wear ear
plugs or muffs during extended periods of
operation.
E, To avoid being suddenly pufled into the blade:
1. Do not wear gloves.
2. Remove all jewelry and loose clothing.
3. Tie back long hair.
4. Rol! long sleeves above the elbow.
G, To avoid an electrical shock, make sure your
fingers do not touch the metal prongs on the
plug when inserting or removing the plug to
or from a live outlet.
H. Never put lubricants on the blade while it's
spinning,
1. To avoid burns or other fire damage, never
use the saw near flammable liquids, vapors or
gases.
J. To avoid injury from unsafe accessories, use
only accessories shown on the recommended
accessories list in this manual.
WHENEVER SAW IS RUNNING:
ii =ii i i =========lllll
I WARNING: Don't allow familiarity (gained trom
Irequent use of your miter saw) to cause a careless
mistake. Always remember that a careless fraction
....#fa second is enough,, t,o cause a severe injury,
1. Before actually cutting with the saw, let it run
for a while. If your saw makes an unfamiliar
noise or if it vibrates excessively, stop immedi-
ately. Turn the saw off. Unplug the saw. Do not
restart until finding and correcting the problem,
2. Never confine the piece being cut off. Never
hold it, clamp it, touch it, or use length stops
against it. It must be free to move sideways. If
confined, it could get wedged against the blade
and thrown violently.
3. Avoid awkward hand positions where a sudden
slip could cause a hand to move into the blade.
4, Let the blade reach ful! speed before cutting.
5. Feed the saw into the workpiece only fast
enough to let the blade cut without bogging
down or binding,
6. Before freeing jammed material, release switch
and unplug the saw. Wait for all moving parts to
stop.
7. 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,

DOUBLE INSULATED
The miter saw 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 compo-
i nents with protective insulation,
Your unit has a plug that looks like the one shown
below
This power tool is equipped with a 2-conductor
cord listed by Underwriters Laboratories (UL). The
plug permits you to use any conventional 120-volt
electrical outlet without necessity for maintaining a
ground connection.
CAUTION: Double insulation does not take the
place of normal safety precautions when operating
this tool.
DANGER: To avoid electrocution:
1. Use only identical replacement parts when
servicing a tool with double insulation. Servicing
should be performed by a qualified service
technician,
2. Do not use in rain or where floor is wet,
This toot is intended for indoor residential use
only.
MOTOR SAFETY PROTECTION
CAUTION: Toavoid motor damage, this motor
should be blown out or vacuumed frequently to
keep sawdust from interfering with normal motor
ventilation.
1, Connect this tool to a 120V, 15-amp branch
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 TOOL, Check
the saw blade to make sure it turns freely. If the
blade is free, try to start the motor again. If the
motor still does not start, refer to the "MotOr
Trouble-Shooting Chart."
3, It the motor suddenly stalls while cutting wood,
release the trigger switch, unplug the tool, and
free the blade from the wood, Then you may
restart the motor and finish the cut.
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. Voltages not more than 10_ above or below
the nameplate voltage can handle normal
loads. For heavy loads, however, the voltage
at motor terminals must equal the voltage
specified on nameplate
5 Most motor troubles may be traced to loose or
incorrect connections, overload, tow voltage
(such as small size wire in the supply circuit) or
to overly long supply circuit wire, Always check
the connections, the load and the supply circuit
whenever motor doesn't work well. Check wire
sizes and length with the Wire Size Chart below,
WIRE SIZES
The use of any extension coro ¢ilt cause some
toss of power. To keep this to a minimum and to
prevent overheating and motor burn-out, use the
table below to determine the minimum wire size
(A.W.G.) extension cord.
For circuits that are farther than 100 feet away
from electrical service box, the wire size must be
increased proportionately in order to deliver ample
voltage to the saw motor.

REMOVING
NUll:: To avoid Injury from unexpected starting,
unplug the saw whenever you are removing or
installing the blade.
1. Unplug the saw from the outlet.
2. Loosen the screw A and 'remove the screw B
holding the lower guard mounting plate to
the upper guard with phillips screwdriver.
3. Lift the lower guard up and tilt the lower guard
assembly back so the arbor screw is exposed.
4. Find the arbor lock between the upper guard
and the miter saw handle. Place changing
blade wrench over arbor screw.
5. Press the arbor lock and hold it in firmly while
turning the wrench clockwise. The arbor lock
will engage after some turning of the wrench.
6. Remove the arbor screw, arbor washer, outer
blade collar, and the blade.
NOTE: Pay attention to pieces removed, noting
their position and direction they face (see illustra-
tion). Wipe the blade collars clean of any saw dust
before installing the new blades.
7. install the new 10" blade. Make sure the
rotation arrow on the btade matches the
clockwise rotation arrow on the upper guard.
8. Instal! the outer blade collar, arbor washer and
arbor screw. Press the arbor lock and turn the
1/2" wrench counter clockwise to secure the
blade. Tighten arbor screw securely.
9. Lower the lower blade guard. Tighten the
screw A and B with a phillips screwdriver.
DANGER: Never use saw without mounting
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.
10. Be sure the arbor lock is reteased so the blade
turns freely.
NOTE: The arbor lock can be damaged by impro-
per use. If the 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.
11. If blade contacts turn table, refer to assembly
and alignment, for adjustment.

1. Inspect your saw. Replace dama_ missing or
failed paris before using th9 llw,:_ _::
2. Wear safety __IU_)that comply
3. For: dusty operations, wear aface shield along
with safety goggles.
4. To avoid injury from jams, slips or thrown
pieces:
a. Choose the right lO-inch diameter blade for
the material and the type of cutting you plan
to do. Use this miter saw to cut only wood,
woodlike products or soft metals like alumi-
num. Other materials may shatter, grab at
the blade or create other dangers.
b. Make surethe direction of rotation arrow on
the blade matches the d_rection arrow on the
saw_ The teeth of the blade should always
point downward at the front of the saw.
c. Make sure the blade is sharp, undamaged
and properly aligned.
d. Make sure the blade and arbor collars are
clean.
e. Make sure the collars' recessed sides are
facing toward the blade.
f. Make sure the recessed side of the blade
washer (just under the arbor screw head)
faces the collar.
gUsing a 1/2" box end wrench, make sure the
arbor screw retaining the blade collars is
firmly hand tightened.
h. Make sure alt clamps and locks are tight and
there is no excessive play in any parts.
5. Never cut more than one workpiece at a time.
6. Make sure the cut off piece can move sideways
Saw
after it's cut off. Otherwise, it could get
wedged against the blade and thrown violent-
ly.
7. Never cut FREEHAND:
a. Brace your workpiece solidly against the
fence and table top so it will not rock or
twist during the cut. Make sure there is no
debris caught beneath the workpiece.
b. Make sure no gaps between the workpiece,
fence and table will cause shifting after the
workpiece is cut in two.
e. Use jigs, fixtures or a different tool for
unstable workpieces.
8. Use extra caution with large, very small or
awkward workpieces:
a. Use extra supports (tables, saw horses,
blocks, etc.) for any workpieces large
enough to tip when not held down to the
table top.
b. Do not use this saw to cut pieces too small
to let you easily hold the work while you
keep the thumb side of your index (pointer)
finger against the cutside edge of the fence.
c, When cutting irregularly shaped workpieces,
plan your work so it will not slip and pinch
the blade. A piece of molding, for example,
must lie flat or be held by a fixture or jig
that will not let it twist, rock or slip while
being cut.
d. Properly support round material such as
dowel rods, or tubing. They have atende-
ncy to roll while being cut, causing the
blade to _bite." To avoid this, use a fixture
designed to properly hold your workpiece,
BODY AND HAND POSITION
Proper positioning of your body and hands when
operating the miter saw will make cutting easier
and safer. Never place hands near cutting area.
Place hand at least 4" from path of blade. Hold
workpiece firmly to the fence to prevent movement
toward the blade. Keep hands in position until
trigger has been released and the blade has
completely stopped. Before making a cut, make a
_dry run _with the power off so you can see the
path of the blade.
WARNING: Do not try to cut short pieces. You I
cannot properly support the workplace and keepl
your hold down hand the required distance from_
the blade. I

MITER CUT
When a miter cut is required, move the saw to the
cJesired angle. Do not stand in front of the saw
table. Move with the handle to the miter angle to
make the cut.
BEVEL CUT
When a bevel cut is required, tilt the blade to the
desired bevel angle. Stand to the left side of the
handle to make the cut.
16
COMPOUND CUT
When a compound cut is required, select the
correct bevel and miter position. Move with the
handle to the miter angle to make the cut:
CUTTING BOWED MATERIAL
Before cutting a workpiece, check to make sure it
is not bowed. If it is bowed the workpiece must be
positioned and cut as illustrated. Do not position
workpiece incorrectly or try to cut the workpiece
without the support of the fence. This will cause
pinching of the workpiece on the blade. The
workpiece could suddenly jump or move and your
hand could hit the blade.
CORRECT INCORRECT
17
WORKPIECE SUPPORT
Long pieces need extra supports. The supports
should be placed along the workpiece so the
workpiece does not sag and your hand holding the
workp=ece is positioned 4 or mor_ _mit_ blade
path.i The support should I_thewo_iece _lay flat
on the base and work t&bie durin_g the cutting
operation;

AUXILIARY FENCE
Certain types of molding need a fence face
extension due to the size and position of the
workpiece. Holes are provided in the fence to
attach an auxiliary fence made of straight wood
typically 1/2 inch thick by 3 inches high by 20
inches long. The auxitary fence is used with the
saw in the 0°bevel position. If a bevel cut is
desired, the auxiliary fence will have to be
removed.

FILLER BLOCKS FOR CUTTING CROWN MOLDINGS
The majority of crown moldings have contact
surfaces of 52o and 38o to the rear surface of the
molding. When•joining the face of :_i!il_r i_
these angles must be mai_ined,:_Thei_ilowing
illustrations show two _m_:that can be used
when cuffing: cr0wn moldings depending on how
the flflerblock is attached to the fence.
When the filler blocks are attached with the face of
the filler blocks pointing upwards, the molding
must be placed on the table upside down.
When the flilar blocks are attached to the fence
wtth_the face of the filler blocks pointing down-
wards, the molding must be placed on the table
right side up, This is the same position as it would
be when nailed between the ceiling and wail.
Make 2 filler blocks 10 inches long. Fasten blocks
securely to fence, For block lace pointing down-
ward, you may need to drill new fastener holes in
the fence.

A compound miter saw !s excellent for cutting
crown molding. Crown molding is difficult to cut
because in order to fit correctly it must be
precisely mitered.
All Standard (U.S.) crown molding has a top rear
angle (fits next to ceiling) of 52° and a bottom rear
angle (fits against wall) of 380.
NOTE:On all above cuts lay molding with broad
back surface flat on table.

Blades marked for 5,500 RPM or higher.
5/8 '1Arbor Hole
REPLACING CARBON BRUSHES
The carbon brushes furnished will fast approxi-
mately 50 hours of running time 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, first unplug the saw, then
remove the black plastic cap on the side of the
motor (caution, this cap is spring loaded by the
brush assembly). Then pull out the brush. Repeat
for the other side. 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 reinstall the same brushes, first make
sure the brushes go back in the way they came
out. This will avoid abreak in period that reduced
performance and increases wear.
LOWER BLADE GUARD
Do not use the saw without the lower guard. The
lower blade guard is attached to the saw for
protection. Should the lower guard become dama-
ged, do not use the saw until damaged guard has
been replaced. Devetop a regular check to make
sure the lower guard is working properly. Clean
the lower guard of any dust or build up with a
damp cloth,
LUBRICATION
All the motor bearings in this tool are lubricated
with asufficient amount of high grade lubricant for
the life of the unit under normal operating
conditions, therefore, no further lubrication is
required. (See below.)
Infrequent Lubrication As Required:
t. Lubrication of arm pivot for free movement.
a. By loosening nut and applying oil to washer
and to contact face (minor).
b, Disassembly means required to grease pivot
bolt and contact faces (major).
NOTE: Disassembly should be done by an
authorized service technician. Removal of the
upper guard and the bolt stop is necessary
before pivot can be disassembled. Pay close
attention to the spring-end positions in the
castings. Mark with chalk to avoid later confu-
sion.
2. Lubrication of-mechanism which pivots lower
guard. Use light household oil (sewing machine
oi!) on metal-to-metal or metal-to-plastic guard
contact areas as required for smooth, quiet
operation. Avoid excess oil, to which sawdust
will cling,
CAUTION: Do not use solvents on the guard.
They could make the plastic 'cloudy" and brittle.
