GENERAL SAFETY INSTRUCTIONS
WARNING! Read and understand all instructions.
Failure to follow all instructions listed below may result
in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered benches and
dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquids, gases, or dust.
Power tools create sparks which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
• Grounded tools must be plugged into an outlet properly
installed and grounded in accordance with all codes and
ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any adapter plugs. Check
with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically
malfunction or break down, grounding provides a low resistance
path to carry electricity away from the user. Applicable only to
Class I (grounded) tools.
Double insulated tools are equipped with a polarized plug
(one blade is wider than the other.) This plug will fit in a
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 a polarized outlet. Do not
change the plug in any way. Double insulation
eliminates
the need for the three wire grounded power cord and grounded
power supply system. Applicable only to Class II (double
insulated) tools. The DW367, DW368 and DW369 are double
insulated tools.
Avoid body contact with grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk
of electric shock if your body is grounded.
Don’t expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord to carry the
tools or pull the plug from an outlet. Keep cord away from
2
English
heat, oil, sharp edges or moving parts. Replace damaged
cords immediately. Damaged cords increase the risk of electric
shock.
When operating a power tool outside, use an outdoor
extension cord marked “W-A” or “W. These cords are rated
for outdoor use and reduce the risk of electric shock. 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 gauge. The smaller the gauge number, the heavier
the cord.

PERSONAL SAFETY
Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use tool while
tired or under the influence of drugs, alcohol, or medication.
A moment of inattention while operating power tools may result
in serious personal injury,
Dress properly. Do not wear loose clothing or jewelry.
Contain long hair. Keep your hair, clothing, and gloves away
from moving parts. Loose clothes, jewelry, or long hair can be
caught in moving parts. Air vents often cover moving parts and
should also be avoided.
Avoid accidental starting. Be sure switch is off before
plugging in. Carrying tools with your finger on the switch or
plugging in tools that have the switch on invites accidents.
Remove adjusting keys or wrenches before turning the tool
on. A wrench or a key that is left attached to a rotating part of
the tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all
times. Proper footing and balance enables better control of the
tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust
mask, non-skid safety shoes, hard hat, or hearing protection
must be used for appropriate conditions.
TOOL USE AND CARE
Use clamps or other practical way to secure and support the
workpiece to a stable platform. Holding the work by hand or
against your body is unstable and may lead to loss of control.
Do not force tool. Use the correct tool for your application.
The correct tool will do the job better and safer at the rate for
which it is designed.
Do not use tool if switch does not turn it on or off. Any tool
that cannot be controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source before making
any adjustments, changing accessories, or storing the tool.
Such preventative safety measures reduce the risk of starting
the tool accidentally.
Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and
clean. Properly maintained tools, with sharp cutting edges are
less likely to bind and are easier to control.
3
English
Check for misalignment or binding of moving parts, breakage
of parts, and any other condition that may affect the tools
operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool, may become hazardous when used on
another tool.
SERVICE
Tool service must be performed only by qualified repair
personnel. Service or maintenance performed by unqualified
personnel could result in a risk of injury.
When servicing a tool, use only identical replacement
parts. Follow instructions in the maintenance section of
this manual. Use of unauthorized parts or failure to follow
maintenance instructions may create a risk of electric shock or
injury.
Additional Safety Instructions for
Circular Saws
DANGER! Keep hands away from cutting area and blade.
Keep your second hand on auxiliary handle, or motor housing.
If both hands are holding the saw, they cannot be cut by the
blade.
WARNING: Blades coast after turn off.
Keep your body positioned to either side of the blade, but
not in line with the saw blade. KICKBACK could cause the
saw to jump backwards (see Causes and Operator Prevention of
Kickback and KICKBACK).
Do not reach underneath the work. The guard can not protect
you from the blade below the work.
Check lower guard for proper closing before each use. Do
not operate saw if lower guard does not move freely and
close instantly. Never clamp or tie the lower guard into the
open position. If saw is accidentally dropped, the lower guard
may be bent. Raise the lower guard with the retracting handle and
make sure it moves freely and does not touch the blade or any
other part, at all angles and depth of cut.
Check the operation and condition of the lower guard spring.
If the guard and the spring are not operating properly, they
must be serviced before use. Lower guard may operate
sluggishly due to damaged parts, gummy deposits, or a buildup
of debris.
Lower guard should be retracted manually only for special
cuts such as “pocket cuts” and “compound cuts. Raise
lower guard by retracting handle. As soon as blade enters the
material, lower guard must be released. For all other sawing,
the lower guard should be allowed to operate automatically.
Always observe that the lower guard is covering the blade
before placing saw down on bench or floor. An unprotected,
coasting blade will cause the saw to walk backwards, cutting
whatever is in its path. Be aware of the time it takes for the blade
to stop after switch is released.
NEVER hold piece being cut in your hands or across your
leg. It is important to support the work properly to minimize body
exposure, blade binding, or loss of control.
Hold tool by insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden
wiring or its own cord. Contact with a “live” wire will also make
exposed metal parts of the tool “live” and shock the operator.
When ripping, always use a rip fence or straight edge guide.
This improves the accuracy of cut and reduces the chance for
blade binding.
4
English
When blade is binding, or when interrupting a cut for any
reason, release the trigger and hold the saw motionless
in the material until the blade comes to a complete stop.
Never attempt to remove the saw from the work or pull the
saw backward while the blade is in motion or kickback may
occur. Investigate and take corrective actions to eliminate the
cause of blade binding.
When restarting a saw in the workpiece, center the saw blade
in the kerf and check that the saw teeth are not engaged into
the material. If saw blade is binding, it may walk up or kickback
from the workpiece as the saw is restarted.
Support large panels to minimize the risk of blade pinching
and kickback. Large panels tend to sag under their own weight.
Support must be placed under the panel on both sides, near the
line of cut and near the edge of the panel.
Do not use dull or damaged blade. Unsharpened or improperly
set blades produce narrow kerf causing excessive friction, blade
binding, and kickback.
Blade depth and bevel adjusting locking levers must be tight
and secure before making cut. If blade adjustment shifts while
cutting, it may cause binding and KICKBACK.
Use extra caution when making a “Pocket Cut” into existing
walls or other blind areas. The protruding blade may cut objects
that can cause kickback.
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).
Always use blades with correct size and shape (diamond
vs. round) arbor holes. Blades that do not match the mounting
hardware of the saw will run eccentrically, causing loss of
control.
Never use damaged or incorrect blade washers or bolts. The
blade washers and bolt were specially designed for your saw, for
optimum performance and safety of operation.
Avoid cutting nails. Inspect for and remove all nails from lumber
before cutting.
Do not operate this tool for long periods of time. Vibration
caused by the operating action of this tool may cause permanent
injury to fingers, hands, and arms. Use gloves to provide extra
cushion, take frequent rest periods, and limit daily time of use.
CAUSES AND OPERATOR PREVENTION OF KICKBACK
Kickback is a sudden reaction to a pinched, bound or misaligned
saw blade, causing an uncontrolled saw to lift up and out of the
workpiece 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
rapidly back toward the operator.
If 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 operator.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
Maintain a firm grip with both hands on the saw and position
your body and arm to allow you to resist kickback forces.
Kickback forces can be controlled by the operator, if proper
precautions are taken.
5
English
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.
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 promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust,
which may cause serious and permanent respiratory or other injury.
Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face
and body.
WARNING: ALWAYS USE SAFETY GLASSES. Everyday
eyeglasses are NOT safety glasses. Also use face or dust mask if
cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY
EQUIPMENT:
ANSI Z87.1 eye protection (CAN/CSA Z94.3),
ANSI S12.6 (S3.19) hearing protection,
NIOSH/OSHA repiratory protection.
WARNING: 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 into a live wire.

TO INSTALL THE BLADE (FIG. 1–4)
1. Place inner clamp washer (G) on saw spindle with the large flat
surface facing out toward the blade.
2. Retract the lower blade guard (F) and place blade on saw spindle
against the inner clamp washer, making sure that the blade will
rotate in the proper direction (the direction of the rotation arrow
on the saw blade and the teeth must point in the same direction
as the direction of rotation arrow on the saw). Do not assume that
the printing on the blade will always be facing you when properly
installed. When retracting the lower blade guard to install the
blade, check the condition and operation of the lower blade guard
to assure that it is working properly. Make sure it moves freely
and does not touch the blade or any other part, in all angles and
depths of cut.
3. Place outer clamp washer (H) on saw spindle with the large flat
surface against the blade and the wording on the outer clamp
washer facing you.
4. Thread blade clamping screw (E) into saw spindle by hand
(screw has right-hand threads and must be turned clockwise to
tighten).
5. Depress the blade lock (I) while turning the saw spindle with the
blade wrench until the blade lock engages and the blade stops
rotating.
6. Tighten the blade clamping screw firmly with the blade wrench.
NOTE: Never engage the blade lock while saw is running, or engage
in an effort to stop the tool. Never turn the saw on while the blade
lock is engaged. Serious damage to your saw will result.
TO REPLACE THE BLADE
1. To loosen the blade clamping screw (E), depress the blade lock
(I) and turn the saw spindle with the blade wrench until the blade
lock engages and the blade stops rotating. With the blade lock
engaged, turn the blade clamping screw counterclockwise with

2. Remove the blade clamping screw (E) and outer clamp washer
(H) only. Remove old blade.
3. Clean any sawdust that may have accumulated
in the guard or clamp washer area and check
the condition and operation of the lower blade
guard as previously outlined. Do not lubricate
this area.
4. Select the proper blade for the application
(see Blades). Always use blades that are the
correct size (diameter) with the proper size
and shape center hole for mounting on the
saw spindle. Always assure that the maximum
recommended speed (rpm) on the saw blade
meets or exceeds the speed (rpm) of the saw.

LOWER BLADE GUARD
WARNING: The lower blade guard is a safety feature which
reduces the risk of serious personal injury. Never use the saw if
the lower guard is missing, damaged, misassembled or not
working properly. Do not rely on the lower blade guard to protect
you under all circumstances. Your safety depends on following
all warnings and precautions as well as proper operation of the
saw. Check lower guard for proper closing before each use as
outlined in Additional Safety Rules for Circular Saws. If the
lower blade guard is missing or not working properly, have the
saw serviced before using. To assure product safety and
reliability, repair, maintenance and adjustment should be
performed by an authorized service center or other qualified
service organization, always using identical replacement
parts.

Cutting Depth Adjustment (Fig. 5, 6)
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments or
accessories.
1. Hold the saw firmly. Raise the depth adjustment lever (J) to
loosen and move shoe to obtain the desired depth of cut,
as shown. Make sure the depth adjustment lever has been
retightened (lowered) before operating the saw.
2. Your saw is equipped with a carbide tipped saw blade for long life
and efficient cutting.
3. 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. Align the appropriate mark on the depth adjustment
strap with triangle on the upper blade guard (K). Your depth is
set.
FIG. 5
FIG. 6
4. 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.
5. 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.
Bevel Angle Adjustment (Fig. 7, 8)
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments or
accessories.
The full range of bevel adjustment on the DW367 is 0 to 50 degrees.
The pivot bracket is graduated in 5 degree increments.
On the DW368 and DW369, the full range of bevel adjustment is
0 to 56 degrees. The pivot bracket is graduated in increments of

Kerf Indicator (Fig. 9)
The front of the saw shoe has a kerf indicator for vertical 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. The ribs
on the front of the DW368 and DW369 shoe are at 1/4" (6.35 mm)
spacing. The notches on the front of the shoe are at 1/2" (13 mm)
intervals.
OPERATION
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments or
accessories.
Switch (Fig. 1)
Pull the trigger switch (B) to turn the motor on. Releasing the trigger
turns the motor off. This tool has no provision to lock the switch in the

English
Workpiece Support
Figures 10 and 12 show proper sawing position. Figures 11 and 13
show an unsafe condition. Hands should be 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 or panel NEAR the cut,
(Fig. 10 and 12). DON’T support board or panel away from the cut
(Fig. 11 and 13). When operating the saw, keep the cord away from
the cutting area and prevent it from becoming hung up on the work
piece.
FIG. 12
FIG. 10
FIG. 11
FIG. 13
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 12 illustrates typical 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.
11
English
Cutting
Support the work so that the waste 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 12 illustrates the RIGHT way to cut off
the end of a board, and Figure 13 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 that the saw is up to full speed before blade contacts
material to be cut. Starting the 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.
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 can cause
pinching of the blade and lead to kickback (Fig. 11).
B. Cutting through material supported at the outer ends only
can cause kickback. 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 can cause kickback.
The falling cut off piece can pinch the blade.
D. Cutting off long narrow strips (as in ripping) can cause
kickback. 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 reduces 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
To make the most efficient cut, the blade should protrude only
far enough to expose 1/2 of a tooth as shown in figure 5. This
allows the shoe to support the blade and minimizes twisting and
pinching in the material. See the section titled Cutting Depth
Adjustment.
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. Over-reaching or operating the 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 up the saw to clear blade can lead to twist if it is not
done carefully.
4. MATERIALS THAT REQUIRE EXTRA ATTENTION
A. Wet lumber
12
English
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 Additional Safety Instructions and Operation for procedures and
techniques that will minimize the occurrence of kickback.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments or
accessories.
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry
air at least once a week. To minimize the risk of eye injury, always
wear ANSI Z87.1 approved eye protection when performing this.
WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
weaken the plastic materials used in these parts. Use a cloth
dampened only with water and mild soap. Never let any liquid get
inside the tool; never immerse any part of the tool into a liquid.
Lubrication
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.
Electric Brake (DW369 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, 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 persists, have the tool serviced at a
D
EWALT certified service center.
Repairs
To assure product SAFETY and RELIABILITY, repairs, maintenance
and adjustment should be performed by a D
EWALT factory service
center, a D
EWALT authorized service center or other qualified
13
English
service personnel. Always use identical replacement parts. (Refer to
Brushes for brush replacement information.)
Brushes
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments or
accessories.
Inspect carbon brushes regularly by unplugging tool, removing the
end 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 removal. Carbon
brushes have varying symbols stamped into their sides, and if either
brush is worn down to the line closest to the spring, the brushes
must be replaced. Use only identical D
EWALT brushes. New brush
assemblies are available at your local service center. Always replace
the end cap after inspecting or servicing brushes. The tool should
be allowed to “run in” (run at no load without a blade) for 5 minutes
before use to seat new brushes.
While “running in” DO NOT TIE, TAPE, OR OTHERWISE LOCK THE
TRIGGER SWITCH ON. HOLD BY HAND ONLY.
Shoe Adjustment
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments or
accessories.
Your shoe has been factory set to assure that the blade is perpen-
dicular to the shoe. If after extended use, you need to re-align the
blade follow the directions below:
ADJUSTING FOR 90 DEGREE CUTS
1. Return the saw to 0 degrees bevel.
2. Place the saw on its side, and retract the lower guard.
FIG. 14
3. Loosen the bevel adjustment lever (L). Place a square against
the blade and the shoe as shown in Figure 14.
4. Using a hex wrench, turn the set screw on the underside of the
shoe until the blade and the shoe are both in flush contact with
the square. Retighten the bevel adjustment lever.
ADJUSTING BEVEL ADJUSTMENT AND DEPTH
ADJUSTMENT LEVERS
It may be desirable to adjust the depth adjustment lever or the bevel
adjustment lever. They may loosen in time and hit the shoe before
tighten ing. To tighten the levers, follow the steps below.
ADJUSTING THE BEVEL ADJUSTMENT LEVER
(DW368, DW369)
NOTE: The following instructions also apply to adjusting the
DW367 and DW368 depth adjustment lever.
1. Using a small screwdriver, pry the lock ring off.
2. Remove the lever and rotate it in the desired direction about 1/8
of a revolution.
3. Reinstall the lock ring with the concave side against the lever.

English
ADJUSTING DEPTH ADJUSTMENT LEVER (DW369 ONLY)
1. Loosen the screw securing the depth adjustment lever.
2. Remove the depth adjustment lever and rotate it to the desired
location, about 1/8 of a revolution.
3. Tighten the lever screw.
Blades
A dull blade will cause inefficient cutting, overload on the saw
motor, excessive splintering and increase the possibility of kickback.
Change blades when it is no longer easy to push the saw through
the cut, when the motor is straining, or when excessive heat is built
up in the blade. It is a good practice to keep extra blades on hand
so that sharp blades are available for immediate use. Dull blades
can be sharpened in most areas; see SAWS-SHARPENING in the
yellow pages.
Hardened gum on the blade can be removed with kerosene,
turpentine, or oven cleaner. Anti-stick coated blades can be used
in applications where excessive build-up is encountered, such as
pressure treated and green lumber.

Règles de sécurité – Généralités
AVERTISSEMENT! Lire et comprendre toutes les
directives, car le non-respect des directives suivantes
peut entraîner un choc électrique, un incendie ou des
blessures graves.
CONSERVER CES DIRECTIVES
ZONE DE TRAVAIL
Garder la zone de travail propre et bien éclairée; les établis
encombrés et les endroits sombres sont propices aux accidents.
Ne pas utiliser les outils électriques dans une atmosphère
explosive, comme à proximité de liquides, de gaz ou de
poussières inflammables; le moteur peut créer des étincelles
et enflammer les vapeurs ou les poussières environnantes.
Tenir les enfants, les visiteurs ou toute autre personne
éloignés lorsqu’on utilise un outil électrique; les distractions
peuvent faire perdre la maîtrise de ce dernier.
MESURES DE SÉCURITÉ - ÉLECTRICITÉ
Les outils mis à la terre doivent être branchés dans une prise
bien installée et mise à la terre conformément à tous les
codes et règlements en vigueur. Ne jamais retirer la broche
de terre ni modifier la fiche. Ne pas utiliser d'adaptateur.
Vérifier auprès d'un électricien qualifié en cas de doute
quant à la mise à la terre de la prise. En cas de défaillance
électrique ou de bris de l'outil, la mise à la terre procure un
chemin de faible résistance au courant qui autrement traverserait
l'utilisateur. Cette protection ne s’applique qu’aux outils de
classe I (mis à la terre).
Les outils à double isolation sont munis d’une fiche polarisée
(c’est-à-dire que l’une des lames est plus large que l’autre),
laquelle ne peut être raccordée qu’à une prise polarisée et
ce, dans un seul sens; on doit l’inverser si on est incapable
de l’enfoncer complètement. Si la fiche ne s’adapte toujours
pas, on doit demander à un électricien qualifié d’installer la
prise appropriée. On ne doit jamais modifier la fiche. La double
isolation
élimine le besoin d’installer un cordon d’alimentation
trifilaire et un système d’alimentation électrique pourvus d’une
mise à la terre; seuls les outils de classe II (à double isolation)
sont munis d’une telle protection. Les modèles DW367, DW368
et DW369 sont des outils à double isolation.
Français

Éviter tout contact entre le corps et les éléments mis à la
terre, comme les tuyaux, les radiateurs, les cuisinières et les
réfrigérateurs, afin de réduire les risques de choc électrique.
Ne pas utiliser l’outil électrique dans des endroits mouillés,
ni l’exposer à la pluie; l’infiltration d’eau à l’intérieur de l’outil
augmente les risques de choc électrique.
Ne pas utiliser le cordon de manière abusive; on ne doit
pas transporter l’outil en le tenant par le cordon, ou utiliser
ce dernier pour le débrancher. On doit tenir le cordon éloigné
des sources de chaleur, de l’huile, des bords tranchants ou
des pièces mobiles. Remplacer immédiatement les cordons
endommagés, car ces derniers augmentent les risques de choc
électrique.
Lorsqu’on utilise un outil électrique à l’extérieur, on ne doit
utiliser que des rallonges conçues pour cet usage, comme
celles de type « W-A » ou « W », afin de réduire les risques de
choc électrique. S’assurer que la rallonge est en mesure de porter
le courant nécessaire à l’outil. Une rallonge de calibre inférieur
entraînera une chute de tension se traduisant par une perte de
puissance et une surchauffe. Le tableau ci-dessous illustre les
calibres que l’on doit utiliser selon la longueur de la rallonge et
l’intensité nominale indiquée sur la plaque signalétique. En cas
de doute, utiliser le calibre suivant. Plus le calibre est petit, plus
la rallonge peut porter du courant.

SÉCURITÉ PERSONNELLE
Rester vigilant en tout temps et faire preuve de jugement
lorsqu’on utilise un outil électrique; ne pas utiliser l’outil
lorsqu’on est fatigué ou sous l’influence de drogues, d’alcool
ou de médicaments, car un moment d’inattention peut entraîner
des blessures graves.
Porter des vêtements appropriés; ne pas porter de vêtements
amples, de gants ni de bijoux, et couvrir ou attacher les
cheveux longs, car ceux-ci peuvent rester coincés dans
les pièces mobiles. Se tenir éloigné des évents puisque ces
derniers pourraient camoufler des pièces mobiles.
Éviter les démarrages accidentels; s’assurer que
l’interrupteur soit en position d’arrêt avant de brancher
l’outil. Ne pas transporter l’outil en laissant le doigt sur
l’interrupteur ni le brancher lorsque l’interrupteur est en position
de marche, car cela pourrait causer un accident.
Retirer les clés de réglage avant de démarrer l’outil; une clé
laissée sur une pièce rotative peut entraîner des blessures.
Ne pas trop étendre les bras; les pieds doivent rester
ancrés fermement au sol afin de maintenir son équilibre
en tout temps et de mieux maîtriser l’outil dans des situations
imprévues.
Utiliser le matériel de sécurité approprié; toujours porter
des lunettes de protection. Porter un masque anti-poussières,
des chaussures antidérapantes, un casque de sécurité ou des
protecteurs auditifs lorsque la situation le requiert.
UTILISATION ET ENTRETIEN DE L’OUTIL
Fixer et soutenir la pièce sur une plate-forme stable au
moyen d’une butée fixe ou de tout autre dispositif semblable;
la pièce est instable lorsqu’on la retient manuellement ou qu’on
l’appuie contre le corps, ce qui peut faire perdre la maîtrise de
l’outil.
Français
18
Ne pas forcer l’outil ni l’utiliser pour des travaux autres que
ceux pour lesquels il a été conçu. Pour obtenir de meilleurs
résultats et prévenir les risques de blessure, laisser l’outil couper
à la vitesse pour laquelle il a été conçu.
Ne pas utiliser l’outil lorsque l’interrupteur marche-arrêt ne
fonctionne pas; tout outil qui ne peut être commandé au moyen
de l’interrupteur est dangereux et doit être réparé.
Débrancher l’outil avant d’effectuer un réglage, de changer
les accessoires ou de ranger l’outil; ces mesures de sécurité
préventives réduisent les risques de démarrage accidentel.
Lorsqu’on n’utilise pas l’outil, le ranger hors de la portée
des enfants ou des personnes non qualifiées; les outils sont
dangereux entre les mains de personnes inexpérimentées.
Bien entretenir l’outil et s’assurer qu’il soit toujours bien
propre et aiguisé; les outils bien entretenus et dont les bords
sont bien tranchants sont moins susceptibles de rester coincés
et sont plus faciles à maîtriser.
Vérifier les pièces mobiles afin de s’assurer qu’elles soient
bien alignées et qu’elles ne restent pas coincées; vérifier
également les pièces afin de s’assurer qu’il n’y ait ni bris
ni aucune autre condition susceptible de nuire au bon
fonctionnement de l’outil; faire réparer l’outil si ce dernier
est endommagé avant de s’en servir à nouveau, car les
accidents sont souvent causés par des outils mal entretenus.
N’utiliser que les accessoires recommandés par le fabricant
pour le modèle en question; un accessoire destiné à un outil
particulier peut devenir dangereux lorsqu’il est utilisé avec un
autre.
ENTRETIEN
L’outil doit être entretenu par le personnel qualifié seulement;
toute maintenance effectuée par une personne non qualifiée
peut entraîner des risques de blessure.
Lors de l’entretien, n’utiliser que des pièces de
rechange identiques et suivre les directives de la section
« Entretien » du présent manuel afin de prévenir les risques de
choc électrique ou de blessure.
Règles de sécurité additionnelles
concernant les scies circulaires
DANGER! Garder les mains éloignées des zones de coupe et
de la lame. Toujours tenir l’outil en plaçant une main sur la poignée
auxiliaire ou le carter du moteur; on protège ses mains en les utilisant
toutes les deux pour tenir l’outil.
AVERTISSEMENT : les lames ne s’arrêtent pas immédiatement
lorsque l’interrupteur est mis en position d’arrêt.
Toujours se placer d’un côté ou de l’autre de la lame
en évitant de se tenir dans son trajet, car la scie pourrait
reculer brusquement par suite d’un REBOND. (Voir les sections
« Causes du rebond et mesures préventives » et « Effet de
rebond ».
Ne pas mettre les mains sous la pièce car il n’y a aucune
protection contre la lame à cet endroit.
Vérifier le protège-lame inférieur afin de s’assurer qu’il soit
bien fermé avant d’utiliser l’outil; ne pas faire fonctionner ce
dernier si le protège-lame ne se déplace pas librement ou
s’il ne se ferme pas instantanément. Ne jamais le bloquer
en position ouverte. Si on laisse tomber la scie, soulever le
protège-lame inférieur au moyen du levier d’escamotage et le
vérifier afin de s’assurer qu’il n’y ait aucun dommage, qu’il se
déplace librement et qu’il n’entre pas en contact avec la lame
ou toute autre pièce de l’outil, quels que soient l’angle et la
profondeur de coupe.
S’assurer que le ressort du protège-lame inférieur soit en
bon état de fonctionnement; sinon, on doit lui faire subir
un entretien avant d’utiliser l’outil. Le protège-lame peut être
