Trigger Switch (Fig. 4)
To turn the saw on, depress the trigger switch. To turn the tool off, release the switch. Allow
the blade to spin up to full operating speed before making the cut. Release the trigger switch
and allow the brake to stop the blade before raising the saw head. There is no provision for
locking the switch on, but a hole is provided in the trigger for insertion of a padlock to lock
the saw off.
Use of XPS
TM
LED Worklight System (Fig. 4)
NOTE: The miter saw must be connected to a power source.
The XPS
TM
LED Worklight System is equipped with an ON/OFF switch (Fig. 4). The XPS
TM
LED
Worklight System is independent of the miter saw's trigger switch.
The light does not need to be on in order to operate the saw.
To cut through an existing pencil line on a piece of wood, turn on the XPS
TM
system, then pull
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.
Cutting With Your Saw
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
workpi ece 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) MATERIALS 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
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 shown in Figure 4.
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 45° 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.
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.
A 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.
NOTE: The rail lock knob shown in Figure 4 must be loose to allow the saw to slide along
its rails.
Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often
45 ° for making corners, but can be set anywhere from zero to 50° left or 60 ° right. Make the
cut as described above.
