Important Safety Instructions
WARNING: When using electric tools, basic safety precautions
should always be followed to reduce risk of fire, electric shock, and
personal injury, including the following:
READ ALL INSTRUCTIONS
Double Insulation
Double insulated tools are constructed throughout with two separate
layers of electrical insulation 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 safety
precautions when operating this tool. The insulation system is for
added protection against injury resulting from a possible electrical
insulation failure within the tool.
CAUTION: WHEN SER VICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or replace damaged cords.
Polarized Plugs
Polarized plugs (one blade is wider than the other) are used on
equipment to reduce the risk of electric shock. When provided, this
plug will fit in the polarized outlet only one way. If the plug does not
fit fully in the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install the proper outlet. Do not change the
plug in any way.

Safety Instructions For All Tools
• KEEP WORK AREA CLEAN. Cluttered areas and benches invite
injuries.
• CONSIDER WORK AREA ENVIRONMENT. Don’t expose power
tools to rain. Don’t use power tools in damp or wet locations. Keep
work area well lit. Do not use tool in presence of flammable liquids
or gases.
• GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with
grounded surfaces. For example; pipes, radiators, ranges, and
refrigerator enclosures.
• KEEP CHILDREN AWAY. Do not let visitors contact tool or
extension cord. All visitors should be kept away from work area.
• STORE IDLE TOOLS. When not in use, tools should be stored in
dry, and high or locked-up place — out of reach of children.
• DON’T FORCE TOOL. It will do the job better and safer at the rate
for which it was intended.
• USE RIGHT TOOL. Don’t force small tool or attachment to do the
job of a heavy-duty tool. Don’t use tool for purpose not intended- for
example- don’t use circular saw for cutting tree limbs or logs.
• DRESS PROPERLY. Do not wear loose clothing or jewelry. They
can be caught in moving parts. Rubber gloves and non-skid
footwear are recommended when working outdoors. Wear
protective hair covering to contain long hair.
• USE SAFETY GLASSES. Also use face or dust mask if cutting
operation is dusty.
• DON’T ABUSE CORD. Never carry tool by cord or yank it to
disconnect from receptacle. Keep cord from heat, oil, and sharp
edges.
• SECURE WORK. Use clamps or a vise to hold work. It’s safer than
using your hand and it frees both hands to operate tool.
• DON’T OVERREACH. Keep proper footing and balance at all times.
• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for
better and safer performance. Follow instructions for lubricating and
1
English
changing accessories. Inspect tool cords periodically and if
damaged, have repaired by authorized service facility. Inspect
extension cords periodically and replace if damaged. Keep handles
dry, clean, and free from oil and grease.
• DISCONNECT OR LOCK OFF TOOLS when not in use, before
servicing, and when changing accessories, such as blades, bits,
cutters.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of
checking to see that keys and adjusting wrenches are removed
from tool before turning it on.
• AVOID UNINTENTIONAL STARTING. Don’t carry tool with finger
on switch. Be sure switch is off when plugging in.
• EXTENSION CORDS. Make sure your extension cord is in good
condition. When using an extension cord, be sure to use one heavy
enough to carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss of power and
overheating. The following table shows the correct size to use
depending on cord length and nameplate ampere rating. If in doubt,
use the next heavier gage. The smaller the gage number, the
heavier the cord.

• STA Y ALER T. Watch what you 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 damaged 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 unless otherwise indicated elsewhere in this instruction
manual. Have defective switches replaced by authorized service
center. Do not use tool if switch does not turn it on and off.
Additional Safety Instructions for Circular
Saws
• CAUTION: When cutting into walls, floors or wherever live electrical
wires may be encountered, 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 CLEAN AND SHARP. Sharp blades minimize
stalling and kickback.
• DANGER: Keep hands away from cutting area. Keep hands
away from blades. Do not reach underneath 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 16 to minimize the risk of blade pinching and
kickback. When cutting operation requires the resting of the saw on
the work piece, the saw shall be rested on the larger portion and the
smaller 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 operator. Release
switch immediately if blade binds or saw stalls. Keep blades sharp.
Support large panels as shown in Figure 16. Use fence or straight
edge guide 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 lower guard with the retracting handle.
• ADJUSTMENTS. Before cutting be sure depth and bevel
adjustments are tight.
• USE ONLY CORRECT BLADES IN MOUNTING. Do 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.
WARNING: Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals known to
cause cancer, birth defects or other reproductive 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 how often you do
this type of work. To reduce your exposure to these chemicals: work in
a well ventilated area, and work with approved safety equipment, such
as those dust masks that are specially designed to filter out
microscopic particles.

SA VE THESE INSTRUCTIONS
Motor
Your D
EWALT tool is powered by a DEWALT motor. Be sure your
power supply agrees with nameplate marking. 120 Volts AC/DC
means your saw will operate on alternating or direct current. Lower
voltage can cause loss of power and can result in overheating. All
DeWalt tools are factory-tested; if this tool does not operate, check the
power supply.
Electric Brake
(DW360/DW361/DW362/DW363 ONLY)
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 two 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 persists, have the tool
serviced at a service center or company authorized service facility.
Brushes
DISCONNECT PLUG FROM POWER SUPPLY BEFORE
SERVICING
Inspect carbon brushes regularly by unplugging tool, removing the
Brush Inspection Cap (Fig. 2) 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 brush is 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 on units so equipped. New
brush assemblies are available at your local service center. The tool
should be allowed to “run in” (run at no load without a 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.
Adjustments and Setup
ATTACHING AND REMOVING BLADES
DISCONNECT PLUG FROM POWER SUPPLY.
To attach the blade, retract lower blade guard and place inner clamp
washer and blade on saw spindle with printed side of blade out (teeth
at bottom of blade pointing forward) (FIG. 1.) Place outer clamp
washer on saw spindle. The larger surfaces of both washers must
face the blade. Thread on blade clamping screw firmly by hand to
hold both blade washers in position.
Lightly depress the blade lock (FIG. 2) while turning the spindle until
the blade stops rotating. Tighten blade clamping screw (clockwise)
firmly with the blade wrench (FIG. 3).
NEVER ENGAGE BLADE LOCK WHILE SAW IS RUNNING, OR
ENGAGE IN AN EFFORT TO STOP THE TOOL. NEVER TURN
SWITCH ON WHEN BLADE LOCK IS ENGAGED. SERIOUS
DAMAGE TO YOUR SAW WILL RESULT.
When removing the blade, first unplug the saw. Engage the blade
lock and unscrew the blade clamping screw by turning it counterclockwise with the blade wrench.
CUTTING DEPTH ADJUSTMENT
DISCONNECT PLUG FROM POWER SUPPLY.
Hold the saw firmly as shown in Figure 4. Loosen (counterclockwise)
the Depth Adjustment Lever and move shoe to obtain the desired
depth of cut, as shown in Figure 5. Make sure the Depth Adjustment

Lever has been retightened (clockwise) before operating saw.
Your saw is equipped with a carbide tipped saw blade for long life and
efficient cutting.
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 projecting 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 kickback.
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 exception to
the above procedure and allow a full tooth to project below the
material, as shown in Figure 5B.
BEVEL ANGLE ADJUSTMENT
DISCONNECT THE SAW FROM THE POWER SUPPLY .
The full range of the Bevel Adjustment is from 0 TO 50 DEGREES.
The quadrant is graduated in increments of 5 degrees.
On the front of the saw is a bevel angle adjustment mechanism (Figure
8) consisting of a calibrated quadrant and a lever or knob. To set the
saw for a bevel cut, loosen (counterclockwise) the quadrant lever or
knob and tilt shoe to the desired angle by aligning the pointer with the
desired angle mark. Retighten lever or knob firmly (clockwise).
NOTE: The quadrant pointer, located between the quadrant lever or
knob and the quadrant, can be adjusted after loosening its screw.
Retighten firmly after adjustment.

and bevel cutting. This indicator enables you to guide the saw along
cutting lines penciled on the material being cut. The indicator lines up
with the left (inner) side of the saw blade, which makes the slot or
“kerf” cut by the moving blade fall to the right 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” (5” for DW359, DW362, DW363)
between the left side of the blade and the left edge of the shoe
(standard 6x lumber). The right dimension is 1-1/2” (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. If 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 (Fig. 10). Retract blade guard.
4. Loosen quadrant lever or knob (Fig. 10). Place a square against
the blade and shoe to adjust the 90° 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.
6. It may be necessary to adjust the quadrant angle pointer to line
up on “O” after shoe has been adjusted.
ADJUSTING THE SHOE PARALLEL TO THE BLADE
(Your saw is adjusted at the factory so that the blade and shoe are
parallel. If these parts become misaligned, adjust as follows.)
1. Disconnect plug from power supply.
2. Loosen the (2) screws at the adjusting bracket at the rear of the

shoe, as shown in Figure 12.
3. Adjust the shoe until it is parallel to the blade by measuring from
the edge of the shoe to the blade, front & rear. You can measure
from the outside edge of the blade to the shoe as shown in
Figure 12 or from the inner edge of the blade to the wider part
of the shoe. (Do not measure from the tips of any saw blade
teeth.)
4. When shoe is parallel, tighten all screws.
ADJUSTING DEPTH ADJUSTMENT & QUADRANT LEVERS OR
KNOBS
It may be desirable to adjust the Depth Adjustment and Quadrant
Adjustment lever or knob. (They will sometimes hit the shoe before
tightening or loosening completely.) To adjust either lever, follow the
steps below.
1. Disconnect plug from power supply.
2. Using a small screwdriver, pry the lock ring off, as shown in Figure
13.
3. Remove the lever and rotate it in the desired direction about 1/8
revolution. (More or less as necessary.)
4. Reinstall the lever and insert the lock ring with concave side
against lever to hold it in place. (Figure 14)
Operation
SWITCH
Pull the trigger switch to turn the motor “ON”. Releasing the trigger
turns the motor “OFF”. Releasing the trigger also automatically
actuates the electric brake on units so equipped. This tool has no
provision to lock the switch in the “ON” position, and should never
be locked “ON” in any way.
WORKPIECE SUPPORT
Figure 15 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.
T o avoid kickback, DO support board or panel NEAR the cut, (Figure
16). DON’T support board or panel away from the cut (Figure 17).
When operating the saw, keep the cord away from the cutting area
and prevent it from becoming hung up on the work piece. Note that
a special Cord Keeper has been provided on the tool’s handle. Press
the cord firmly into the cord keeper to keep it out of the way but in
sight so you know where it is at all times.
WARNING: It is important to support the work properly and to hold the
saw firmly to prevent loss of control which could cause personal
injury; Figure 15 illustrates typical hand support of the saw.
ALWAYS DISCONNECT SAW BEFORE MAKING ANY ADJUSTMENTS! 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.
CUTTING
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 work piece 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.
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
forward into kerf can result in kickback.
Push the saw forward at a speed which allows the blade to cut
without 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
7
English
382782-00/DW359 7/18/00 10:59 AM Page 7
8
over-heating of the motor.
Should your cut begin to go off the line, don’t try to force it back on.
Release the switch and allow blade to come to a complete stop. Then
you can withdraw the saw, sight anew, and start a new cut slightly
inside the wrong one. In any event, withdraw the saw if you must shift
the cut. Forcing a correction inside the cut can stall the saw and lead
to kickback. IF SAW STALLS, RELEASE THE TRIGGER AND BACK
THE SAW UNTIL IT IS LOOSE. BE SURE BLADE IS STRAIGHT IN
THE CUT AND CLEAR OF THE EDGE BEFORE RESTARTING.
As you finish a cut, release the trigger and allow the blade to stop
before lifting the saw from the work. As you lift the saw, the springtensioned telescoping guard will automatically close under the blade.
Remember the blade is exposed until this occurs, never reach under
the work for any reason whatsoever. When you have to retract the
telescoping guard manually (as is necessary for starting pocket cuts)
always use the retracting lever.
NOTE: When cutting thin strips, be careful to ensure that small cutoff
pieces don’t hang up on inside of lower guard.
When ripping (cutting with the grain) the use of a rip fence is
recommended. (See Figure 7)
POCKET CUTTING
DISCONNECT PLUG FROM POWER SUPPLY WHEN MAKING
THIS OR ANY OTHER ADJUSTMENT. Adjust saw shoe so blade
cuts at desired depth. Tilt saw forward and rest front of the shoe on
material to be cut. Using the retracting lever, retract blade guard to an
upward position. Lower rear of shoe until blade teeth almost touch
cutting line. Now release the blade guard (its contact with the work
will keep it in position to open freely as you start the cut). Start the
motor and gradually lower the saw until its shoe rests flat on the
material to be cut. Advance saw along the cutting line until cut is
completed. Release trigger and allow blade to stop completely before
withdrawing the blade from the material. When starting each new cut,
repeat as above. Never tie the blade guard in a raised position.

RIGHT
382782-00/DW359 7/18/00 10:59 AM Page 8
Kickback
When the saw blade becomes pinched or twisted in the cut, kickback
can occur. The saw is thrust rapidly back toward the operator. 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.
Kickback is more likely to occur when any of the following conditions
exist.
1. IMPROPER WORKPIECE SUPPORT
A. Sagging or improper lifting of the cut off piece causing
pinching of the blade.
B. Cutting through material supported at the outer ends only
(see Figure 17). As the material weakens it sags, closing
down the kerf and pinching the blade.
C. Cutting off a cantilevered or overhanging piece of material
from the bottom up in a vertical direction. The falling cut off
piece can pinch the blade.
D. Cutting 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 of cut setting increases
loading on the unit and susceptibility to twisting of the blade in
the kerf. It also increases the surface area of the blade avaliable
for pinching under conditions of kerf close down.
3. BLADE TWISTING (MISALIGNMENT IN CUT)
A. Pushing harder to cut through a knot, a 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 while 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 (material freshly cut or not kiln dried)
C. Pressure treated lumber (material treated with preservatives
or anti-rot chemicals)
5. USE OF DULL OR DIRTY BLADES
Dull blades cause increased loading of the saw. To
compensate, an operator will usually push harder which further
loads the unit and promotes twisting of the blade in the kerf.
Worn blades may also have insufficient 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 angle
to the shoe and greater blade surface in the material increase
the chance for binding and misalignment (twist) to occur.
7. RESTARTING A CUT WITH THE BLADE TEETH JAMMED
AGAINST THE MATERIAL
The saw should be brought up to full operating speed before
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, twisting,
or misalignment of the blade could cause kickback. Refer to the
sections on “Adjustments And Set-Up” 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 increase the possibility of kickback.
It 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-SHARPENING” in the Yellow Pages). In fact, many lower
priced blades can be replaced with new ones 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 trichlorethylene, kerosene, turpentine or
oven cleaner.

Cleaning and Lubrication
Use only mild soap and a damp cloth to clean the tool. Many
household cleaners contain chemicals which could seriously damage
plastic. Also, do not use gasoline, turpentine, lacquer or paint thinner,
dry cleaning fluids or similar products. Never let any liquid get inside
the tool; never immerse any part of the tool into a liquid.
Self lubricating ball and roller bearings are used in the tool and
relubrication is not required. However, it is recommended that, once
a year, you take or send the tool to a service center for a thorough
cleaning, inspection and lubrication of the gear case.
Important
To assure product SAFETY and RELIABILITY, repairs, maintenance
and adjustment (including brush inspection and replacement) should
be performed by authorized service centers or other qualified service
organizations, always using identical replacement parts.
