Attaching Dust Bag
A zippered cloth dust bag is included with your saw. To
attach the bag, fit the plastic opening firmly over the
dust spout (9).
NOTE: The saw can also be used with a vacuum
cleaner hose attached to the dust spout or without any
attachment.
Adjustments
PERFORM ALL ADJUSTMENTS WITH THE MITER
SAW UNPLUGGED
NOTE: Your miter saw is fully and accurately adjusted
at the factory at the time of manufacture. If readjust-
ment due to shipping and handling or any other reason
is required, follow the steps below to adjust your saw.
Miter Scale Adjustment
Place a square against the saw's fence and blade, as
shown in Figure 4. (Do not touch the tips of the blade
teeth with the square. To do so will cause an inaccurate
measurement.) Loosen the miter clamp handle (4) as
shown in Figure 5 and swing the miter arm until the
miter latch (5) locks it at the 0 miter position. Do not
tighten the clamp handle. If the saw blade is not exact-
ly perpendicular to the fence, loosen the two screws
that hold the handle to the base (shown in Figure 6)
and move the arm of the saw left or right until the blade
is perpendicular to the fence, as measured with the
square. Retighten the two screws. Pay no attention to
the reading of the miter pointer at this point.
Guard Actuation and Visibility
The blade guard on your saw has been designed to
automatically raise when the arm is brought down and to
lower over the blade when the arm is raised. The guard
can be raised by hand when installing or removing saw
blades or for inspection of the saw. NEVER RAISE THE
BLADE GUARD MANUALLY UNLESS THE SAW IS
TURNED OFF.
NOTE: Certain special cuts will require that you manu-
ally raise the guard. To do this, simply place your right
thumb on the upper side of the guard and roll the guard
up just enough to clear the workpiece. Never tie up or
otherwise prevent the guard from operating normally.

OPERATION

Plug the saw into any power source. Refer to the name-
plate for voltage. Be sure the cord will not interfere with
your work.
Switch
To turn the saw on, depress the trigger switch (16). To
turn the tool off, release the switch. There is no provision
for locking the switch on.
Body and Hand Position (See figure 7)
Proper positioning of your body and hands when oper-
ating the miter saw will make cutting easier, more accu-
rate and safer. Never place hands near cutting area.
Place hands no closer than 6" from the blade. Hold the
workpiece tightly to the table and the fence when cut-
ting. Keep hands in position until the trigger has been
released and the blade has completely stopped.
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 7.
Cutting With Your Saw
NOTE: Although this saw will cut wood and many non-
ferrous materials, we will limit our discussion to the cut-
ting of wood only. The same guidelines apply to the
other materials. DO NOT CUT FERROUS (IRON AND
STEEL) MATERIALS OR MASONRY WITH THIS SAW.
Do not use any abrasive blades.
Crosscuts
NOTE: Cutting of multiple pieces is not recommended,
but can be done safely by ensuring that each piece is
held firmly against the table and fence.
A crosscut is made by cutting wood across the grain at
any angle. A straight crosscut is made with the miter
arm at the zero degree position. Set the miter arm at
zero, hold the wood on the table and firmly against the
fence. Turn on the saw by squeezing the trigger switch.
When the saw comes up to speed (about 1 second)
lower the arm smoothly and slowly to cut through the
wood. Let the blade come to a full stop before raising
arm.
Miter crosscuts are made with the miter arm at some
angle other than zero. This angle is often 45 degrees for
making corners, but can be set anywhere from zero to
47 degrees left or right. After selecting the desired miter
angle, be sure to tighten the miter clamp handle (4).
Make the cut as described above.
Bevel Cuts
A bevel cut is a crosscut made with the saw blade at a
bevel to the wood. In order to set the bevel, loosen the
bevel clamp knob (17) and move the saw to the left as
8
