General Safety Instructions
WARNING! Read and understand all instructions. Failure to follow all instruc-
tions listed below, may result in electric shock, fire and/or serious personal injury.
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
Keep bystanders, children, and visitors away while operating a power tool. Distractions
can cause you to lose control.
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.

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 medica-
tion. A moment of inattention while operating power tools may result in serious personal
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 cover moving parts and should 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.
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
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.
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 Instructions
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.
Allow the motor to come to a complete stop before withdrawing the blade from the kerf
(the slot created by cutting). A moving blade may impact the workpiece causing a broken
blade, workpiece damage or loss of control and possible personal injury.
Keep handles dry, clean, free from oil and grease. This will enable better control of the
Keep blades sharp. Dull blades may cause the saw to swerve or stall under pressure.
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 sawdust from treated lumber. Do not allow dust to get into
your mouth, eyes or lay on the skin. Wear protective clothing whenever possible.
The label on your tool may include the following symbols.
V ................volts A ..................amperes
Hz ..............hertz W..................watts
min..............minutes ................alternating current current no load speed
................Class II Construction ..................earthing terminal alert symbol .../min ..........revolutions per minute
Your DEWALT tool is powered by a DEWALT-built motor. Be sure your power supply agrees with
the nameplate markings.
Volts 50/60 Hz or “AC only” means your tool must be operated only with alternating current and
never with direct current. Volts DC-60 Hz or AC/DC means your tool may be operated with either
alternating or direct current.
Voltage decrease of more than 10% will cause loss of power and overheating. All D
EWALT tools
are factory tested; if this tool does not operate, check the power supply.
Variable Speed Switch (Fig. 1)
This switch has a button “A”, mounted in the trigger, which can be rotated to vary the blade
stroke speed.
(a) For “Free Hand” speed control (the further the trigger is pulled, the higher the S.P.M.) rotate
the button to the 7 position (clockwise).
(b) To set the trigger switch to produce a selected speed each time the trigger is squeezed, first
rotate the button toward 7 until it stops. Then fully depress the trigger, press the locking but-
ton “B”, and release the trigger. The tool will stay ON. Now, rotate the button “A” toward the
1 and you will notice a decrease in speed. Continue rotating the button until the desired
speed is reached. Pull the trigger and release to turn the tool OFF. At this setting the saw
will run at the selected speed each time the trigger is pulled and the trigger may be locked
ON at the selected speed.
Variable Speed Switch (DW323) (Fig. 2)
This tool has a button “A,” which can be rotated to vary the blade strokes-per-minute (S.P.M.)
To turn the tool ON, slide the switch (B) forward. To lock the switch ON, slide the switch in the
two notches in the saw’s housing and release the trigger (Fig.2A). Rotate button “A” to reach the
desired speed. Press the flat, rear edge of the trigger to unlock the trigger and turn the tool OFF.
Dust Blower (Fig. 3)
Your jigsaw is equipped with a dust blower to clear the cutting area of debris created by the
blade. To turn the blower on, slide the switch to the top position. To turn the blower off, slide the
switch to the bottom position.
Removeable Shoe Cover (Fig. 4)
Your jig saw includes a removeable plastic shoe cover. Use this cover when cutting surfaces that
scratch easily, such as paint, laminate or veneer. Put the shoe on as shown in Fig. 4. Slide the
cover to the rear to ensure that the two tabs (A) shown lock on the shoe.
Straight Line or Orbital Cutting Action (Fig. 5)
For cutting softer materials your jig saw features orbital cutting action. Soft materials, like wood
and plastic, permit deep penetration of individual saw teeth. The orbital action set on 3 thrusts
the blade forward on the cutting stroke and greatly increases cutting speed over conventional jig
saws. Harder materials like metal should be cut using the straight line cutting action (0) or a very
low orbital setting. To select straight line or orbital cutting adjust the lever (A) on the saw as
Bevel Cutting Adjustment (Fig. 6 & 7)
Bevel cuts may be made at any angle between 0° and 45°.
a. Lift the shoe lever on the bottom of the tool (A).
b. Align the arrow on the housing wdith the line on the shoe Fig. 7.
c. Rotate the shoe to the desired angle.
After setting the shoe, tighten it by returning the shoe lever to its oringinal position.
NOTE: The shoe will be difficult to bevel at first. Ensure the shoe lever is up and the two arrows
shown are aligned. Gently rock the shoe from side to side to loosen.
