SAVE
THESE
INSTRUCTIONS
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.
Double lnsulation
Your
unit
is DOUBLE
INSUI-ATED.
This means that
it is
con-
structed
throughout
with TWO separate
"layers"
of electrical
insu-
lation or one
DOUBLE thickness
of insulation between
you
and
the tool's electrical
system.
Tools
built
with this
insulation system are
not intended to be
grounded.
As a result,
your
tool
is equipped
with
a two-prong
plug
which
permits
you
to
use extension cords
without concern for
maintaining a
ground
connection.
NOTE: DOUBLE
INSULATION does
not take the
place
of
normal

precautions
when
operating
this tool.
This insulation sys-
tem is for

l,UTION:
When
servicing
all tools, USE ONLY
IDENTICAL
nEPIâCEMENT
PARTS. Repair or
replace damaged cords.
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.
lt 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.
lf this condition
persists,
turn the saw
on and off
four or
five times.
lf the brake still
does
not stop the blade
in about
2 sec-
onds,
the
problem
may be
worn brushes.
Replace the brushes as
described
below and
try
the saw again.
lf the
problem
still
per-
sists,
have the tool
seruiced at a
service
center or authorized
ser-
vice facility.

Keep brushes
clean and
sliding
freely
in their

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

both brushes.
Use
of the
correct
grade
of
brush
is essential
for
proper
operation
of

New brush assemblies
are
available
at
your
local service
center.
The tool should
be allowed
to
"run
in"
(run
at
no load with-
out blade)
for 10
minutes before
use to
seat new brushes.
This is
especially
important
for saws equipped
with electric brakes,
which
may
be

in operation
until the brushes
are
properly
seated
(worn

NOTE: To adjust the depth of cut
pointer
for various

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.
lf 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 boüom
of the
gullet
in
front of
it.
Study
Figures
5A and 58
to
determine
what
one
half tooth means.
(5A
shows
one half tooth
projecting
below
the surface
and
figure
58
shows a whole tooth
projecting
below the sufface).
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
material
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 excep-
tion to the above
procedure
and allow a
full tooth to
project
below
the
material,
as shown
in Figure
58.
BEVEL ANGLE ADJUSTMENT
DISCONNECT THE
SAW
FROM THE POWER
SUPPLY.
The full range of the Bevel Adjustment is from
0
to 50 DEGREES.
ïhe
quadrant
is
graduated
in increments of 1 degree.
On the
front
of the saw
is
a bevel angle adjustment
mechanism
(Figure
8) consisting of a calibrated
quadrant
and a
knob. To
set
the saw
for
a bevel cut,
loosen
(counterclockwise)
the
quadrant
knob
and
tilt
shoe
to the
desired angle by aligning
the
pointer
with
the desired angle
mark. Retighten knob firmly
(clockwise).

KERF INDICATOR
The front
of
the
saw shoe
has
a
kerf indicator
(Figure
8)
for verti-
cal and bevel cutting.
This indicator
enables
you
to
guide
the saw
along
cutting lines
penciled
on the
material
being cut.
The indica-
tor
lines
up with the left
(inner)
side of

the
indicator.
Guide along the
penciled
cutting line so that
the kerf
falls
into
the waste or
surplus
material
-
See
Figure
9.
Figure 9
shows the dimensions of the shoe. Note
that
the left side is 5
1/2"
between the lefi side
of
the
blade and the
left
edge
of the shoe
(standard
6x lumber). The right
dimension
is 1 112"
(standard
2x
lumber).
SHOE
ALIGNMENT
Your saw has
been set at the factory
for
accurate
vertical
cuts
(a
90 degree angle between the bottom of the shoe and
the blade).
The edge of the
shoe
has
also
been
set
parallel
to the blade
so
that it will not bind when using an edge
guide,
lf
the saw should
ever need adjustment, it may be done as follows:
ADJUSTING FOR
90" CUTS
1. DISCONNECT PLUG FROM POWER
SUPPLY.
2. Adjust the saw to 0" bevel.
3.
Place saw on blade
side
(Figure
10). Retract
blade
guard.
4. Loosen
quadrant
knob.
(Figure
10). Place
a
square against
the blade
and
shoe to
adjust the
g0'
setting.
5. Loosen the
hex nut
and move the
adjustment
screw so that
the shoe
will
stop at the
proper
angle
as shown
in Figure 11.
Lock the screw in
place
by tightening the hex nut.

WORKPIECE SUPPORT
Figure 13 shows
proper
sawing
position.
Note
that
hands
are
kept away from cutting area, and
power
cord
is
positioned
clear
of the cutting area so that
it will not
get
caught or hung up on the
work.
To
avoid
kickback, DO support
board
of
panel
NEAR the cut
and
on both sides of the cut,
(Figure
14). DON'T support board or
panel
away
from the
cut,
(Figure
15). When ripping long narrow
strips,
support cut-otf waste material.
When operating the saw, keep the cord
away
from the cutting
area and
prevent
it
from becoming
hung
up on the
workpiece.
Note that
a special Cord
Keeper has
been
provided
on
the
tool's
handle,
as shown
in Figure 4.
Simply
press

WARNING:
lt is important
to support the work
properly
and to hold
the saw firmly
to
prevent
loss
of control which
could cause
personal
injury; Figure 13
illustrates
ÿpical
hand
support of the saw.
ALWAYS
DISCONNECT
SAW
BEFORE
MAKING ANY ADJUST-
MENTS!
Place the work
with its
"good"
side
-
the
one on
which
appearance is most important
-
down. The
saw cuts upward,
so any
splintering will
be on the work face
that is up when
you
saw
it.
Support the work
so that the cut will
be on
your
right. Place the wider
portion
of the saw shoe
on that
part
of the workpiece which
is solidly
supported,
not on the
section that will fall
off
when
the cut is made. As
examples, Figure
16 illustrates
the RIGHT way
to cut off the end of a
board,
and Figure 17 the
WRONG way. Always
clamp work. Don't try
to hold
short
pieces
by hand!
Remember to
support cantilevered and
overhanging material.
Use caution when sawing material
from below.
CUTTING
Be
sure saw is up to
full speed before
blade contacts material to be
cut.
Starting saw with
blade against material to
be
cut
or
pushed
for-
ward into kerf
can result in kickback.
Push
the
saw
forward
at
a
speed which
allows the blade
to cut
with-
out laboring. Hardness
and toughness
can vary even in the same
piece
of material,
and knotty or
damp sections can
put
a
heavy load
on
the saw. When
this happens,
push
the saw more slowly, but hard
enough
to keep it working without
much
decrease
in
speed.
Forcing
the
saw can cause rough
cuts, inaccuracy, kickback
and over-heating
of the motor.
Should
your
cut begin to
go
off the line,

Kickback
When the
saw
blade becomes
pinched
or
twisted
in the
cut,
kick-
back
can
occur.
The
saw is thrust
rapidly
back
toward
the
opera-
tor.
When
the blade
is
pinched
or
bound
tightly
by the
kerf
closing
down,
the
blade
stalls
and the
motor
reaction
drives
the unit
backward.
When
the
blade becomes
twisted
or misaligned
in the
cut,
the
teeth at
the
back edge
of
the blade
can
dig
into the
top
surface
of
the
wood
causing
the blade
to climb
out
of
the
kerf and
jump
back
toward
the
oPerator.
kictiOack
is
more
likely to
occur
when any
of the
following
condi-
tions
exist.
1. IMPROPER
WORKPIECE
SUPPORT
A. Sagging
or
improper
litting of
the cut
off
piece
causing
pinching
of
the blade.
B. ôutting
through
material
supported
at
the
outer
ends
only
(see
Figure
15).
As the
material
weakens
it
sags,
closing
down
the
kerf and
pinching
the blade.
C.
Cutting
of
a cantilevered
or
overhanging
piece
oJ
material
from the
bottom
up
in a vertical
direction.
The falling
cut off
piece
can
pinch
the
blade.
D. Ôutting
off long
narrow
strips
(as
in
ripping).
The cut
off
strip
can sag
or twist
closing
the
kerf and
pinching
the
blade.
E. Snagging
the
lower
guard
on a surface
below
the
material
being
cut
momentarily
reducing operator
control'
The saw
can
lift
partially
out
of the
cut
increasing
the
chance
of
blade
twist.
2. IMPROPER
DEPTH
OF CUT
SETTING
ON
SAW
Using the
saw with
an
excessive
depth
cut setting
increases
loading
on
the unit
and susceptibility
to
twisting
of the blade in
the kerf.
lt
also increases
the
surface
area of the
blade avail-
able for
pinching
under
conditions
of kerf close
down.
3. B|-ADE
TWIST|NG
(M|SALIGNMENT
tN
CUT)
A. Pushing
harder
to
cut through
a
knot,
nail,
or a hard
grain
area
can cause
the
blade to twist.
B. Trying
to turn
the
saw in the
cut
(trying
to
get
back
on the
marked
line)
can cause
blade
twist.
C. Extended
reach
or
operating
saw with
poor
body
control
(out
of
balance),
can result
in
twisting
the
blade.
D.
Changing
hand
grip
or body
position
white
cutting
can
result
in
blade
twist.
E. Backing
unit up to
clear
blade
can lead
to twist if not
done
carefully.
4.
MATERIALS
THAT
REQUIRE
EXTRA
ATTENTION
A. Wet
lumber
B.
Green lumber
(materialfreshly
cut
or not kiln
dried)
C. Pressure
treated
lumber
(material
treated with
preserva-
tives
or anti-rot
chemicals)
5.
USE OF DULL
OR DIRTY
BI.ADES
Dull
or dirÿ blades
cause increased
loading
of the
saw, To
compensate,
an operator
will
usually
push
harder
which
fur-
ther loads
the
unit
and
promotes
twisting
of the
blade in
the
kerf.
Worn
blades
may
also
have
reduced
body
clearance
which
increases
the chance
of
binding
and increased
loading.
6. LIFTING
THE
SAW WHEN
MAKING
BEVEL
CUTS
Bevel_
cuts
require
special
operator
attention
to
proper
cutting
techniques -
especially
guidance
of the
saw. Both
blade
anglé
to the
shoe
and
greater
blade
surface in
the material
increale
the chance
for
binding
and misalignment (twist)
to
occur.
7.
RESTARTING
A
CUT
WITH THE
BLADE
TEETH
JAMMED."
AGAINSTTHE
MATERIAL
I
The
saw
should
be
brought
up to full
operating
speed
beforèÿ
starting
a cut
or
restarting
a cut
after the
unit has
been
stopped
with
the blade
in
the kerf. Failure
to do
so can
cause
stalling
and kickback.
Any
other
conditions
which
could result
in
pinching,
binding,
twisÈ
ing,
or misalignment
of
the blade
could
cause kickback.
Èefer
to
the
sections
on
'Adjustments
And
SetUp"
and
"Operation',
for
procedures
and
techniques
that will
minimize
the occurrence
of
kickback.
Blades
A
dull blade
will
cause
slow, inefficient
cutting
overload
on the
saw motor,
excessive
splintering
and could increase
the
possibili-
ÿ
of kickback.
lt is
a
good practice
to keep
extra
blades'on
hand
so that
sharp
blades
are
available while
the dull ones
are
being
sharpened
(See "SAWS-SHARPEN|NG"
in
the
ye[ow pages).
tn
fact,
many
lower
priced
blades
can
be replaced
with new
ônes
at
very
little
cost
over the
sharpening
price.
Hardened
gum
on the
blade
will
slow down
the cutting.
This
gum
can best
be removed
with
kerosene,
turpentine
or
oven cleanôr.

Extension
Cords
Double-insulated
tools have
2-wire
cords and
can be
used with 2-
wire
or 3-wire
extension
cords.
Only round-jacketed
extension
cords should
be used. lf
the extension
will

outside, the
cord must
be suitable for
outdoor
use. Any
cord marked
as out-
door
can be used for
indoor work.
The letter
"W'on
the cord
jack-
et
indicates
that the cord is
suitable for
outdoor
use.
An
extension cord
must have
adequate
wire
size
(AWG
or
American
Wire
Gauge) for
safety,
and to
prevent
loss
of
power
and overheating.
The
smaller the
gauge
number
of
the
wire,
the
greater
the capacity
of the cable,
that is 16
gauge
has more
capacity
than
18
gauge.
When using
more
than one extension
to
make
up
the total length,
be sure
each individual
extension
con-
tains
at
least
the minimum
wire
size.
