while cutting. Although the louvers dramatically reduce
flying debris, they are openings in the guard and safety
glasses should be worn at all times when viewing through
the louvers.
AUTOMATIC ELECTRIC BRAKE (120 VOLT ONLY)
Your saw is equipped with an automatic electric blade
brake which stops the saw blade within 5 seconds of
trigger release. This is not adjustable.
On occasion, there may be a delay after trigger release
to brake engagement. On rare occasions, the brake may
not engage at all and the blade will coast to a stop.
If a delay or "skipping" occurs, turn the saw on and off 4
or 5 times. If the condition persists, have the tool serviced
by an authorized D Walt service center.
E
Always be sure the blade has stopped before removing it
from the kerf. The brake is not a substitute for guards or
for ensuring your own safety by giving the saw your
complete attention.

Brushes

DISCONNECT PLUG FROM POWER SUPPLY
Inspect carbon brushes regularly by unplugging tool,
removing the brush inspection cap (Figure 3) and
withdrawing the brush assembly. Keep brushes clean
and sliding freely in their guides. Always replace a used
brush in the same orientation in the holder as it was prior
to its removal. Carbon brushes have varying symbols
stamped into their sides, and if the brush is worn down to
the line closest to the spring, they must be replaced. Use
only identical D WALT brushes. Use of the correct grade

of brush is essential for proper operation of electric

service centers. The tool should be allowed to "run in"

(run at no load) for 10 minutes before use to seat new

brushes. The electric brake may be erratic in operation

until the brushes are properly seated (worn in).
While "running in" DO NOT TIE, TAPE, OR OTHERWISE
LOCK THE TRIGGER SWITCH ON. HOLD BY HAND
ONLY.

Operation

Plug the saw into any household 60 Hz 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 as shown
in Figure 15. To turn the tool off, release the switch.
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.

CUTTING WITH YOUR SAW

NOTE: Although this saw will cut wood and many non-
ferrous 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

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 miter arm at the zero degree
position. Set the miter arm at zero, hold the wood on the
table and firmly against the fence. Turn on the saw by
squeezing the trigger switch as shown in Figure 15.
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.
Miter crosscuts are made with the miter arm at some
angle other than zero. This angle is often 45 degrees for
making corners, but can be set anywhere from zero to 48
degrees left or right. After selecting the desired miter
angle, be sure to tighten the miter clamp knob. 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 and move the saw to the left as
desired. (It is necessary to move the left side of the fence
to allow clearance). Once the desired bevel angle has
been set, tighten the bevel clamp knob firmly.
Bevel angles can be set from 3 degrees right to
48 degrees left and can be cut with the miter arm set
between zero and 48 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.
If small fibers of wood still split out at the rear of the
workpiece, stick a piece of masking tape on the wood
where the cut will be made. Saw through the tape and
carefully remove tape when finished.
For varied cutting applications, refer to the list of
recommended saw blades for your saw and select the
