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 manually
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 nameplate
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 fig. G)
Proper positioning of your body and hands when operating
the mitre saw will make cutting easier, more accurate 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 cutting. 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 Fig. G.
Cutting with your saw
Note: Although this saw will cut wood and many nonferrous
materials, we will limit our discussion to the cutting 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 mitre arm at the zero
degree position. Set the mitre 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.
Mitre crosscuts are made with the mitre arm at some
angle other than zero. This angle is often 45º degrees for
making corners, but can be set anywhere from zero to
degrees left or right. After selecting the desired mitre
angle, be sure to tighten the mitre 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 desired.
Once the desired bevel angle has been set, tighten the bevel
clamp knob firmly. Bevel angles can be set up to 45º
degrees left and can be cut with the mitre arm set between
zero and 47º degrees right or left.
Quality of cut
The smoothness of any cut depends on a number of
variables. Things like material being cut, blade type,
blade sharpness and rate of cut all contribute to the
quality of the cut.
When smoothest cuts are desired for molding and other
precision work, a sharp (60 tooth carbide) blade and a
slower, even cutting rate will produce the desired results.
Ensure that material does not creep while cutting, clamp
it securely in place. Always let the blade come to a full
stop before raising arm.
