Trigger Switch (Fig. M)
To turn the saw on, push the lock-off lever
saw will run while the switch is depressed. Allow the blade to spin up to full operating speed
before making the cut. To turn the saw off, release the switch. Allow the blade to stop before
raising the saw head. There is no provision for locking the switch on. A hole

Always be sure the blade has stopped before removing it from the kerf.

Your saw has a built-in dust port
that allows either the supplied dust bag or a shop vacuum
system to be connected.
nOTE: This saw has a dust port equipped with an AirLock
that connects tools to dust extraction shrouds to minimize cleanup on the jobsite.

To cut through an existing pencil line on a piece of wood, turn on the XPS
down on the operating handle to bring the saw blade close to the wood. The shadow of the
blade will appear on the wood. This shadow line represents the material that the blade will
remove when performing a cut. To correctly locate your cut to the pencil line, align the pencil
line with the edge of the blade's shadow. Keep in mind that you may have to adjust the miter or
bevel angles in order to match the pencil line exactly.
Through-Cutting Operations (Fig. A)
If the slide feature is not used, ensure the saw head is pushed back as far as possible and the
rail lock knob is tightened. This will prevent the saw from sliding along its rails as the workpiece
is engaged.
nOTE: Although this saw will cut wood and many non-ferrous materials, we will limit our
detailed discussion to the cutting of wood only. The same guidelines apply to the other
materials. DO NOT CUT FERROUS (IRON AND STEEL) MAT ERIALS OR MASONRY WITH THIS SAW.
Do not use any abrasive blades.
nOTE: Refer to guard Actuation and Visibility in the Adjustments section for important
information about the lower guard before cutting.
Crosscuts (Fig. A, O)
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 and lock the miter arm at zero, hold the wood
firmly on the table and against the fence. With the rail lock knob tightened, 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.
When cutting anything larger than a 2 x 8 (51 x 203 mm [2 x 6 (51 x 152) at 45º miter]) use an
out-down-back motion with the rail lock knob loosened. Pull the saw out, toward you, lower the
saw head down toward the workpiece, and slowly push the saw back to complete the cut. Do
not allow the saw to contact the top of the workpiece while pulling out. The saw may run toward
you, possibly causing personal injury or damage to the workpiece.

. The
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.
nOTE: To provide greater crosscut capacity with reduced stroke, the blade on the DWS780
extends deeper into the table. As a result, a greater lifting force on the workpiece may be
experienced during the cut.
CAUTION: Always use a work clamp to maintain control and reduce the risk of workpiece
damage and personal injury, if your hands are required to be within 6" (152 mm) of the blade
during the cut.

Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often
45º for making corners, but can be set anywhere from zero to 50º left or 60° right. Make the cut as
1
described above.
When performing a miter cut on workpieces wider than a 2 x 6 that are shorter in length, always
place the longer side against the fence
To cut through an existing pencil line on a piece of wood, match the angle as close as possible.
Cut the wood a little too long and measure from the pencil line to the cut edge to determine
which direction to adjust the miter angle and recut. This will take some practice, but it is a
commonly used technique.

Bevel Cuts
A bevel cut is a crosscut made with the saw blade leaning at an angle to the wood. In order
to set the bevel, loosen the bevel lock
