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 flam-
mable 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 adaptor plugs. Check with a qualified elec-
tician 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 elim-
inates the need for the three wire grounded power cord and grounded power supply system.
Applicable only to Class II (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 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.

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 bal-
ance 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 dan-
gerous 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.
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 mainte-
nance 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 Specific Safety Rules
Hold tool by insulated gripping surfaces when performing an operation where the cut-
ting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make
exposed metal parts of the tool “live” and shock the operator.
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.
CAUTION: Wear appropriate personal hearing protection during use. Under some con-
ditions 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 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 microscop-
ic 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 injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.

Switch (Variable Speed) (Fig. 1)
The variable speed trigger switch (A) will give you added versatility. The further the trigger is
depressed the higher the speed of the saw. To turn the tool “OFF” release the trigger.
CAUTION: Use of very slow speed is recommended only for beginning a cut. Prolonged use
at very slow speed may damage your saw.
Blade Clamping DW303 (Fig. 2)
CAUTION: TURN OFF AND UNPLUG SAW.
To install blade into saw:
1. Loosen set screw(B).
2. Insert blade shank (C) from the front between the reciprocating shaft (D) and the blade
clamp(E). Locate hole in blade (F) over pin (G) on reciprocating shaft.
3. Tighten set screw. If the blade should break off and the shank does not come out of the
clamp, be sure the set screw is loose and eject the shank with a nail or pointed object.
CAUTION: THE BLADE GUARD IS THERE FOR YOUR SAFETY. DO NOT REMOVE IT.
Blade Clamp Release Lever DW303M and DW304P (Fig.
3)
CAUTION: TURN OFF AND UNPLUG SAW.
To install blade into saw:
1. Pull blade clamp release lever (H) up.
2. Insert blade shank from the front.
3. Push blade clamp release lever down.
To remove blade from saw:
1. Open blade clamp release lever.
2. Remove blade.
CAUTION: THE BLADE GUARD IS THERE FOR YOUR SAFETY. DO NOT REMOVE IT.
Cutting with Blade in Horizontal Position DW304P Only
(Fig. 4A)
Installing a blade in the horizontal orientation allows cutting close to floors, walls or ceilings
where limited clearance is available. Ensure that the Blade Guard is pressed against the fram-
ing to avoid kickback.
Flush-To Cutting (Fig. 5)
The compact design of the saw motor housing and spindle housing permits extremely close cut-
ting to floors, corners and other difficult areas.
CAUTION: When sawing into walls, floors or wherever “live” electrical wires may be encoun-
tered, DO NOT TOUCH ANY FRONT METAL PARTS OF THE TOOL! Hold the tool only by the
plastic handle and housing to prevent electric shock if you saw into a “live” wire.
CAUTION: Always wear eye protection while operating this power tool.
Wood Cutting (Fig. 6)
Before cutting any type of wood, be sure it is firmly anchored or clamped to prevent slipping.
Place blade lightly against work to be cut, switch on saw motor and allow it to obtain maximum
speed before applying pressure. Always hold saw firmly with both hands while cutting.
Whenever possible, the saw shoe must be held firmly against the material being cut. This will
prevent the saw from jumping or vibrating and minimize blade breakage.
