to useyourpowertool.
CAUTION

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 10 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.

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.

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

SPECiFiCSAFETYiNSTRUCTiONS

10.USE only blade collars specified for
your saw.

FOR THiS COMPOUND MITER SAW
.

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

11 .NEVER use blades larger in
diameter than 12 inches.
12.NEVER apply lubricants to the
blade when it is running.

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

13.ALWAYS check the blade for
cracks or damage before operation.
Replace a cracked or damaged
blade immediately.
14.NEVER use blades recommended

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

for operation at less than 4200 RPM.
15.ALWAYS keep the blade guards in
place and use at all times.
16.NEVER reach around the saw
blade.

KEEP HANDS out of the path of the
saw blade. If the workpiece you are
cutting would cause your hands to
be within 8-3/4 in. of the saw blade,
the workpiece should be clamped in
place before making the cut.

17.MAKE SURE the blade is not
contacting the workpiece before the
switch is turned ON.
1&iMPORTANT: After completing the
cut, release the trigger and wait for
the blade to stop before returning
the saw to the raised position.

BE SURE the blade is sharp, runs
freely and is free of vibration.
ALLOW the motor to come up to full
speed before starting a cut.

1&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.

KEEP THE MOTOR AiR SLOTS
CLEAN and free of chips or dust.
ALWAYS

MAKE SURE all handles

are tight before cutting, even if the
table is positioned in one of the
positive stops.

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

9. BE SURE both the blade and the
collar are clean and the arbor bolt is
tightened securely.
7

21 .NEVER cut small pieces. If the
workpiece being cut would cause
your hand or fingers to be within
8-3/4 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.
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
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.
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.

Installing Blade (Fig. K, L, M)

i_lk WARNING]
Un=plug the miter saw before
changing/installing the blade.
1. Install a 12 in. blade with a 5/8 in.
arbor (or a 1 in. arbor blade with
a 5/8 in. reducer) making sure the
rotation arrow on the blade matches
the clockwise rotation arrow on the
upper guard, and the blade teeth
are pointing downward.
2. Place the blade collar (7) against
the blade and on the arbor. Thread
the arbor bolt (6) on the arbor in a
counterclockwise direction. (Fig. M)

iMPORTANT: Make sure the flats of
the blade collars are engaged with
the flats on the arbor shaft. Also, the
flat-side of the arbor collar must be
placed against the blade.
Place the blade wrench on the arbor
bolt (6).
Press the arbor lock button (5),
holding it in firmly while turning
the blade counterclockwise. When
it engages, continue to press the
arbor lock button in, while tightening
the arbor bolt securely. (Fig. L)
Rotate the cover plate (3) back to its
original position until the slot in the
cover plate engages with the upper
cover plate screw (1) and lower cover
plate screw (2). While holding the
lower blade guard, tighten the screw
with a Phillips screwdriver. (Fig. K)
NOTE: The lower blade guard must
be raised to the upright position to
access the cover plate screw.
Lower the clear retractable blade
guard (4) and verify the operation of

Be sure the arbor lock is released
so the blade turns freely by spinning
the blade until the arbor lock
disengages.

WARNINGI

o 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.
o 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 saw table.
