Bench Mounting; Changing/Installing New Saw Blade; Removing The Blade; Installing The Blade - DeWalt DW718 Instruction Manual

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 12.7mm (1/2") 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 surely
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)
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.
FIG. 3

Removing the Blade

1. Unplug the saw.
2. Raise the arm to the upper position and raise the lower guard (A) as
far as possible.
3. Loosen, but do not remove guard bracket screw (B) until the bracket
can be raised far enough to access the blade screw. Lower guard
will remain raised due to the position of the guard bracket screw.
FIG. 3A
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 15.88mm (5/8"), the 25.4mm (1")
blade adapter (H) is not used.
Installing a Blade
1. Unplug the saw.
2. With the arm raised, the lower guard held open and the pivot plate
raised, place the blade on the spindle, onto the blade adapter [if using
a blade with a 25.4mm (1") diameter blade hole] and against the
inner clamp washer 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 15.88mm (5/8") diameter blade hole,

the blade adapter will not be used and should be stored in a safe place
for future use.
5. Return the guard bracket to its original position and firmly tighten the

Transporting the Saw

TURN OFF AND UNPLUG THE MITER SAW BEFORE ATTEMPTING TO
MOVE IT OR MAKE ANY ADJUSTMENTS WHAT SO EVER!
In order to conveniently carry the miter saw from place to place, a
carrying handle has been included on the top of the saw arm and hand
indentations in the base, as shown in Figure 4.

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 readjustment due to shipping and handling or any
F
other reason is required, follow the steps below to adjust your saw.
Once made, these adjustments should remain accurate. Take a little time
G
now to follow these directions carefully to maintain the accuracy of which
your saw is capable.
MITER SCALE ADJUSTMENT (FIG. 5)
Place a square against the saw's fence and blade, as shown. (Do not
H
touch the tips of the blade teeth with the square. To do so will cause an
inaccurate measurement.) Loosen the miter lock handle and swing the
miter arm until the miter latch locks it at the 0 miter position. Do not
tighten the lock handle. If the saw blade is not exactly
perpendicular to the fence, loosen the four screws that hold the miter
scale to the base and move the scale left
I
or right until the blade is perpendicular to the fence, as measured with the
square. Retighten the four screws. Pay no attention to the reading of the
miter pointer at this time.
MITER POINTER ADJUSTMENT (FIG. 6, 7)
Loosen the miter lock handle to move the miter arm to the zero position.
With the miter lock handle loose allow the miter latch to snap into place
as you rotate the miter arm to zero. Observe the pointer and miter scale
shown in Figure 6. If the pointer does not indicate exactly zero, loosen
the screw holding the pointer in place, reposition the pointer and tighten
the screw.
BEVEL SQUARE TO TABLE ADJUSTMENT (FIG. 8)
To align the blade square to the table, lock the arm in the down position.
Place a square against the blade and table taking care to not have the
square not touch a blade tooth. Loosen the bevel lock handle and ensure
the bevel latch has firmly snapped into place at 0 degrees. If the saw
blade is not exactly perpendicular to the table, loosen the nut which holds
the 0 bevel latch plate to the table. Adjust the nut to allow some drag
between the parts. Gently tap the motor or the belt cover to move the
upper assembly until the blade is square to the table. Tighten the lock nut.
