outdoors,
use only extension
cords intended
for use outdoors
and so marked.

STAYALERT.
Watch whatyou
are doing.
Use common
sense.
Do not operate
tool when you
are tired.

CHECK
DAMAGED
PARTS.
Before
further use of the tool, a guard or other part that is dam-
aged
should
be carefully
checked
to determine
that it will operate
properly
and perform
its
intended
function.
Check for alignment
of moving
parts, binding
of moving
parts, breakage
of
parts, mounting,
and any other conditions
that may affect
its operation.
A guard or other part
that is damaged
should
be properly
repaired
or replaced
by an authorized
service
center

Safety
Instructions
for Circular
Saws
i_ CAUTION:
When
cutting
into walls, floors or wherever
live electrical
wires may be encoun-
tered,
DO NOT
TOUCH
ANY
METAL
PARTS
OF THE TOOL!
Hold the tool only by insulated
grasping
surfaces
to prevent
electric
shock
if you cut in the live wire.
*
KEEP
GUARDS
IN PLACE
AND IN WORKING
ORDER.
Never
wedge
or tie lower guard
open. Check operation
of lower guard
before
each use. Do not use if lower guard
does not
close briskly over saw blade.
_
CAUTION:
If saw is dropped,
lower guard may be bent, restricting
full return.
*
KEEP BLADES
CLEANAND
SHARP.
Sharp blades
minimize
stalling
and kickback.
l& DANGER:
Keep hands away from cutting
area. Keep hands away from blades.
Do not reach
undemeath
work while blade
is rotating.
Do not attempt
to remove
cut material
when blade is
moving.
CAUTION:
Blades
coast after turn off.
*
SUPPORT
LARGE
PANELS.
Large panels
must be supported
as shown
in Figure 14 to min-
imize the risk of blade pinching
and kickback.
When cutting
operation
requires
the resting
of
the saw on the work piece, the saw shaft be rested on the larger portion
and the smafler
piece
cut off.
*
USE RiP FENCE.
Always
use a rip fence or straight
edge guide
when ripping.
*
GUARD
AGAINST
KICKBACK.
Kickback
occurs
when the saw stalls rapidly
and is driven
back
towards
the operate_
Release
switch
immediately
if blade
binds
or saw
stalls.
Keep
blades
sharp.
Support large panels
as shown
in Figure
14. Use fence
or straight

when ripping.
Don'f force tool. Stay alert-exercise
control.
Don't remove
saw from work during
a cut while the blade is moving.
*
LOWER
GUARD.
Raise lewerguard
with the retracting
handle.
*
ADJUSTMENTS.
Before
cutting
be sure depth and bevel adjustments
are tight.
*
USE
ONLY
CORRECT
BLADES
IN MOUNTING.
De not
use blades
with
incorrect
size
holes.
Never use defective
or incorrect
blade
washers
or bolts.
*
AVOID
CUTTING
NAILS.
Inspect
for and remove
all nails from lumber
before
cutting.
_, CAUTION:
Wear appropriate
hearing
protection
during
use. Under
some
conditions
and
duration
of use, noise
from this product
may contribute
to hearing
loss.
WARNING:
Some
dust created
by power
sanding,
sawing,
grinding,
drilling, and other con-
struction
activities
contains
chemicals
known
to cause cancer,
birth defects
or other reproduc-
tive harm.
Some
examples
of these
chemicals
are:
*
lead from lead-based
paints,
*
crystalline
silica from bricks
and cement
and other masonry
products,
and
*
arsenic
and chromium
from chemically-treated
lumber
(CCA).
Your risk from these
exposures
varies,
depending
on hew often you
de this type of work. To
reduce
your
exposure
to these
chemicals:
work
in a weft ventilated
area,
and work
with
approved
safety
equipment,
such as those
dust masks
that are specially
designed
to filter out
microscopic
particles.
*
Avoid
prolonged
contact
with
dust
from
power
sanding,
sawing,
grinding,
drilling,
and
other
construction
activities.
Wear protective
clothing
and
wash exposed
areas
with soap
and water. Allowing
dust to get into your mouth,
eyes, or lay on the skin may pro-
mote absorption
of harmful
chemicals.
_ WARNING:
Use of this tool can generate
and/or disburse
dust, which may cause serious
and
permanent
respiratory
or other inju_
Always
use NIOSH/OSHA
approved
respiratory
protection
appropriate
for the dust exposure.

Motor
Your DEWALT tool is powered
by a DEWALT-built
motor. Be sure your power supply
agrees with
nameplate
marking.
120 Volts AC/DC
means your saw will operate
on alternating
or direct cur-
rent. Lower voltage
will cause
loss of power and can result
in over-heating.
All DEWALT
tools
are factory-tested;
if this tool does not operate,
check
the power supply.
Electric
Brake
Your saw has an automatic
electric
brake which
is designed
to stop the blade from coasting
in
about two seconds
after you release
the trigger switch.
It is useful when making
certain
cuts in
wood where
a coasting
blade would
result
in a wide, imprecise
cut.
Occasionally,
under certain
conditions,
the brake will not function
properly
and won't stop the
saw in the 2 seconds
discussed
above.
If this condition
persists,
turn the saw on and off four or
five times. If the brake still does not stop the blade in about 2 seconds,
the problem
may be worn
brushes.
Replace
the brushes
as described
below
and try the saw again. If the problem
still per-
sists, have the tool serviced
at a DEWALT certified
service
center.
Brushes
DISCONNECT
PLUG
FROM
POWER
SUPPLY
Inspect
carbon
brushes
regularly
by unplugging
tool, removing
the Brush
Inspection
Cap (A)
(Figure
1) 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 removal.
Carbon
brushes
have varying
symbols stamped
into their sides, and if the brushes
are worn down
to the line closest to the spring, they must be replaced.
Use only identical DEWALT brushes. Always
replace
both brushes.
Use of the correct grade of brush is essential
for proper operation
of electric
brakes.
New brush assemblies
are available
at your local DEWALT certified service center. The tool
should
be allowed
to "run in" (run at no load without
blade) for 10 minutes before use to seat new
brushes.
This is especially
important
for saws equipped
with electric brakes, which 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.

To attach
the blade, retract
lower blade guard
(C) and place inner clamp washer
(D) and blade
(E) on saw spindle
with teeth at bottom
of blade pointing
forward.
Install outer clamp washer
(F).
The larger surfaces
of both washers
must face the blade. Thread
on blade clamping
screw
(G)
firmly by hand to hold washers
in position.
Lightly depress
the blade lock (B) while turning
the spindle
until the blade stops rotating.
Tighten

it counter-clockwise
with the blade wrench.
CUTTING
DEPTH
ADJUSTMENT
(FIG. 4)
DISCONNECT
PLUG
FROM
POWER
SUPPLY.
Loosen
(counterclockwise)
the Cutting
Depth
Adjustment
Knob
(H). Lift the saw
handle,
as
shown,
to adjust
it to the desired
height. Tighten
the knob to secure
it in place. If depth of cut
cannot
be adjusted,
inspect
parts for damage
and service
as required
before
use. A scale and
pointer
(I) is provided
to enable
you to select
a specific
depth of cut. Simply
align the pointer to
the desired
depth of cut.
NOTE:
To adjust the depth of cut pointer
for various
blade diameters,
loosen
the Cutting
Depth
Adjustment
Knob and raise the saw until the blade
just touches
the workpiece
and tighten
the
knob. This is the zero depth of cut position.
If required,
loosen
the screw
that holds the pointer
and adjust to the zero indicator
mark. The saw is now adjusted
to accurately
indicate
the depth
of cut for the blade
used.
For the most efficient
cutting
action
using a carbide
tipped saw blade, set the Depth Adjustment
so that about one half of a tooth projects
below the surface
of the wood to be cut. The height of
a whole
tooth
is the distance
from the tip of the tooth
to the bottom
of the gullet
in front of it.
Study
Figures 5A and 5B to determine
what one half tooth means.
(5A shows one half tooth pro-
jecting
below
the surface
and figure 5B shows
a whole
tooth projecting
below
the surface.)
Setting
the saw at the proper
cutting depth keeps blade friction
to a minimum,
removes
sawdust
from between
the blade
teeth, results
in cooler,
faster sawing
and reduces
the chance
of kick-
back.
A method
of checking
for the correct cutting
depth is shown
in Figure 6. Lay a piece of the mate-
rial you plan to cut along the side of the blade, as shown
in the figure,
and observe
how much
tooth projects
beyond
the material.
NOTE:
When
using a non carbide
tipped blade, make
an exception
to the above
procedure
and
allow a full tooth to project below
the material,
as shown
in Figure 5B.

The full range of the Bevel Adjustment
is from 0 to 50 DEGREES.
The quadrant

ed in increments
of 1 degree.
On the front of the saw is a bevel angle adjustment
mechanism
consisting
of a calibrated
quad-
rant (J) and a knob,
(K). To set the saw for a bevel cut, loosen
(counterclockwise)
the quadrant
