AUTOMATIC ELECTRIC BRAKE

Your saw is equipped with an automatic electric blade
brake which stops the saw blade within 5 seconds of trig-
ger 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 motor end cap, (Figure 3) removing the brush
cap 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. Use only identical D
Use of the correct grade of brush is essential for proper
operation of electric brake. New brush assemblies are
available at D WALT service centers. The tool should be
E
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 shown in
Figure 14. To turn the tool off, release the switch. There is
no provision for locking the switch on, but a hole is provid-
ed 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-fer-
rous materials, we will limit our discussion to the cutting of
wood only. The same guidelines apply to the other materi-
als. DO NOT CUT FERROUS (IRON AND STEEL) MATE-
RIALS 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

MITER
SCALE
FIG. 20
FIG. 17 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 firm-
ly against the fence. Turn on the saw by squeezing the trig-
ger switch shown in Figure 14.
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 50 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

ANGLE "A"
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 50 degrees right or left. Ensure the
fence has been adjusted properly. When cutting left bevel,
or right miter compound cuts, it will be necessary to
remove the adjustable fence.

QUALITY OF CUT

The smoothness of any cut depends on a number of vari-
ables. 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 - 80 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 work-
piece, apply a piece of masking tape on the wood where
the cut will be made. Saw through the tape and carefully
remove tape when the cut is finished.
For varied cutting applications, refer to the list of recom-
mended saw blades for your saw and select the one that
best fits your needs. (Page 3)
BODY AND HAND POSITION (FIG. 15)
Proper positioning of your body and hands when operating
the miter saw will make cutting easier, more accurate and
safer. Never place hands near cutting area. Place hands
no closer than 6" from the blade. Hold the workpiece tight-
ly to the table and the fence when cutting. Keep hands in
position until the trigger has been released and the blade
has completely stopped. ALWAYS MAKE DRY RUNS
