Bench Mounting; Features And Controls - DeWalt DWS780 Manual De Instrucciones

Familiarization
Your miter saw is fully assembled in the car ton.
Open the box and lift the saw out by the
con venient lifting handle, as shown in
Figure 2.
Place the saw on a smooth, flat surface such
as a workbench or strong table.
Examine Figure 4 to become familiar with
the saw and its various parts. The section on
adjus tments will refer to these terms and you
must know what and where the parts are.
CAUTION: Pinch hazard. To reduce the
risk of injury, keep thumb underneath the
operating handle when pulling the handle
down. The lower guard will move up as the operating handle is pulled down, which could
cause pinching. The operating handle is placed close to the guard for special cuts.
Press down lightly on the operating handle and pull out the lock down pin. Gently release the
downward pressure and hold the operating handle, allowing it to rise to its full height. Use the
lock down pin when carrying the saw from one place to another. Always use the lifting handle
to transport the saw, or use the hand indentations shown in Figure 4.

Bench Mounting

Holes are provided in all 4 feet to facilitate bench mounting, as shown in Figure 4. (Two
different-sized holes are provided to accommodate different sizes of screws. Use either hole,
it is not necessary to use both.) Always mount your saw firmly to a stable surface to prevent
movement. To enhance the tool's portability, it can be mounted to a piece of 1/2" (12.7 mm)
or thicker plywood which can then be clamped to your work support or moved to other job
sites and reclamped.
NOTE: If you elect to mount your saw to a piece of plywood, make sure that the mounting
screws don't protrude from the bottom of the wood. The plywood must sit flush on the work
support. When clamping the saw to any work surface, clamp only on the clamping bosses
where the mounting screw holes are located. Clamping at any other point will interfere with
the proper operation of the saw.
CAUTION: To prevent binding and inaccuracy, be sure the mounting surface is not warped
or otherwise uneven. If the saw rocks on the surface, place a thin piece of material under one
saw foot until the saw sits firmly on the mounting surface.
IMPORTANT SAFETY INSTRUCTIONS
Changing or Installing a New Saw Blade (Fig. 3)
WARNING: To reduce the risk of serious personal injury, turn off the tool and
disconnect it from the power source before attempting to move it, change
accessories or make any adjustments.
CAUTION:
• Never depress the spindle lock button while the blade is under power or coasting.
• Do not cut ferrous metal (containing iron or steel) or masonry or fiber cement product
with this miter saw.
Removing the Blade (Fig. 3)
1. Unplug the saw.
2. Raise the arm to the upper position and raise the lower guard (A) as far as possible.
FIG. 2
3. Loosen, but do not remove guard bracket screw (B) until the bracket can be raised far
enough to access the blade screw (E). Lower guard will remain raised due to the position
of the guard bracket screw.
4. Depress the spindle lock button (C) while carefully rotating the saw blade by hand until the
lock engages.
5. Keeping the button depressed, use the other hand and the wrench provided (D) to loosen
the blade screw. (Turn clockwise, left-hand threads.)
6. Remove the blade screw (E), outer clamp washer (F), blade (G) and blade adapter (H), if
used. The inner clamp washer (I) may be left on the spindle.
NOTE: For blades with a blade hole of 5/8" (15.88 mm), the 1" (25.4 mm) blade adapter (H)
is not used.
Installing a Blade (Fig. 3)
1. Unplug the saw.
2. With the arm raised, the lower guard held open and the guard bracket raised, place
the blade on the spindle, onto the blade adapter (if using a blade with a 1" [25.4 mm]
diameter blade hole) and against the inner blade clamp with the teeth at the bottom of
the blade pointing toward the back of the saw.
3. Assemble the outer clamp washer onto the spindle.
4. Install the blade screw and, engaging the spindle lock, tighten the screw firmly with
wrench provided (turn counterclockwise, left-hand threads).
NOTE: When using blades with a 5/8" (15.88 mm) diameter blade hole, the blade adapter will
not be used and should be stored in a safe place for future use. The separate blade adapter
is not available on all models.
5. Return the guard bracket to its original position and firmly tighten the guard bracket screw
to hold bracket in place.
WARNING:
• The guard bracket must be returned to its original position and the guard
bracket screw tightened before activating the saw.
• Failure to do so may allow the guard to contact the spinning saw blade
resulting in damage to the saw and severe personal injury.
Transporting the Saw
WARNING: To reduce the risk of serious personal injury, turn off the tool and
disconnect it from the power source before attempting to move it, change
accessories or make any adjustments.
WARNING: To reduce the risk of serious personal injury, ALWAYS lock the rail lock
knob, miter lock handle, bevel lock handle, lock down pin and fence adjustment knobs before
transporting saw.
In order to conveniently carry the miter saw from place to place, a lifting handle has been
included on the top of the saw arm and hand indentations in the base, as shown in Figure 4.

FEATURES AND CONTROLS

WARNING: To reduce the risk of serious personal injury, turn off the tool and
disconnect it from the power source before attempting to move it, change
accessories or make any adjustments.
MITER CONTROL (FIG. 5)
The miter lock handle and miter latch button allow you to miter your saw to 60° right and 50°
left. To miter the saw, lift the miter lock handle, push the miter latch button and set the miter
angle desired on the miter scale. Push down on the miter lock handle to lock the miter angle.
