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 accor-
dance 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 mal-
function 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
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 refriger-
ators. 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 out-
let. 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.
• Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your fin-
ger 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 plat-
form. 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.
• Check for misalignment or binding of moving parts, breakage of parts, and any other con-
dition 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 Specific Safety Instructions
• 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 make exposed
metal parts of the tool "live" and shock the operator.
• Keep handles dry, clean, free from oil and grease. This will enable better control of the tool.
• Keep blades sharp. Dull blades may cause the saw to swerve or stall under pressure.
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.
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.

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
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 your desired speed. Fully depress the trigger, press the locking but-
ton "B", and release the trigger. The tool will stay ON. 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.
Removable Shoe Cover (Fig. 4)
Your jig saw includes a removable 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
shown.
Bevel Cutting Adjustment (Fig. 6 & 7)
Bevel cuts may be made at any angle between 0° and 45°.
TO ADJUST THE SHOE:
a. Lift the shoe lever on the bottom of the tool (A).
b. Align the arrow on the housing width 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 original 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.
At 0˚, the shoe may slide back to allow for cutting in tight work areas. Lift the shoe lever, slide
the shoe back and depress the lever to lock. If necessary tighten the shoe lever with the screw
(B).
Attaching Blades (Fig. 8)
UNPLUG TOOL. To remove the blade, lift the knob on the top of the jig saw approximately 1/4".
Rotate the knob counterclockwise until the clamp is open (Figure 8a). Do not force the knob once
it stops. Insert the blade as shown. Make sure the back edge of the blade fits into the support roller.
Tighten clamp by turning top knob clockwise until you hear a click. Push knob down.
For "T" shank blades, insert blade to the shoulder of the shank.
Splinter Insert (Fig. 9)
Insert the plastic shoe to add extra contact at the cutting area. The minimizes splinters. The shoe
also presses against sheet metal to lessen vibration.
