General Power Tool Safety Warnings
WARNING! Read all safety warnings and all instructions. Failure to follow the
warnings and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a ground fault
circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric
shock.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating power tools may
result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have the
switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. A wrench
or a key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
g) If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection can
reduce dust-related hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your application. The
correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool
that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the risk of starting the power tool
accidentally.
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits, etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could result
in a hazardous situation.
5) SERVICE
a) Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
Additional Specific Safety Instructions for Jig Saws
•Hold power tool by insulated gripping surfaces, when performing an operation
where the cutting accessory may contact hidden wiring or its own cord. Cutting
accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and
could give the operator an electric shock.
•Use clamps or another practical way to secure and support the workpiece to a
stable platform. Holding the work by hand or against your body leaves it unstable and may
lead to loss of control.
•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
tool.
•Keep blades sharp. Dull blades may cause the saw to swerve or stall under pressure.
• Clean out your tool often, especially after heavy use. Dust and grit containing metal
particles often accumulate on interior surfaces and could create an electric shock hazard.
•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.
•Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or
long hair can be caught in moving parts.
•An extension cord must have adequate wire size (AWG or American Wire Gauge)
for safety. The smaller the gauge number of the wire, the greater the capacity of the cable,
that is 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in
line voltage resulting in loss of power and overheating. When using more than one extension
to make up the total length, be sure each individual extension contains at least the minimum
wire size. 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.

Motor
Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than
10% will cause loss of power and overheating. DEWALT tools are factory tested; if this tool does
not operate, check power supply.
COMPONENTS (Fig. 1, 2)
WARNING: Never modify the power tool or any part of it. Damage or personal injury could
result.
A. Trigger switch D. Keyless blade lever
B. Lock button E. Shoe
C. Speed control dial
OPERATION
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Trigger Switch (Fig. 1)
To start the jig saw, squeeze the trigger switch (A).
To slow and stop the jig saw, release the trigger switch.
For continuous operation, squeeze the trigger switch then depress the lock button (B). Once
lock button is depressed, release the trigger switch.
To release from continuous operation, squeeze the trigger and the lock will disengage.
Variable Speed Switch (Fig. 1, 2)
The variable speed is controlled in two ways: speed control dial (C) and the trigger switch (A).
SPEED CONTROL DIAL
By rotating the speed control dial (C) in either direction, the maximum speed or strokes-per-
minute at which the blade will cut is adjusted. The speed control dial adjusts the speed that the
blade will cut from approximately 500 SPM to approximately 3,100 SPM.
TRIGGER SWITCH
As the trigger switch is pressed in, the strokes-per-minute continue to increase, but not to exceed
the maximum setting on the speed control dial. As the trigger is released, the blade strokes-per-
minute reduce.
Blade Installation and Removal (Fig. 3)
TO INSTALL A BLADE
1. Lift the keyless blade lever (D).
2. Insert the blade into the clamp mechanism (F) while guiding the back of the blade into the
groove of the guide rollers (G).
3. The shank should be completely inside the clamp mechanism as shown in Figure 4.
4. Release the keyless blade lever.
TO REMOVE A BLADE
1. Lift the keyless blade lever (D).
2. With a slight shake the blade will drop out.
CAUTION: Do not touch used blades, they may be hot. Personal injury may result.
Bevel Cutting Adjustment (Fig. 5)
Bevel cuts may be made at any angle between 0° and 45°. The shoe is adjusted by loosening
the screw (H) on the bottom of the tool and rotating the shoe to the desired angle. After setting
the shoe, tighten the screw firmly and use saw in the normal manner.
Cutting Action – Orbital or Straight (Fig. 6)
CAUTION: Check that the tool is not locked ON before connecting it to a power supply.
If the trigger switch is locked ON when the tool is connected to the power supply, it will start
immediately. Damage to your tool or personal injury may result.
This jig saw is equipped with four cutting actions, three orbital and one straight. Orbital action
has a more aggressive blade motion and is designed for cutting in soft materials like wood or
plastic. Orbital action provides a faster cut, but with a rougher cut across the material. In orbital
action, the blade moves forward during the cutting stroke in addition to the up and down motion.
NOTE: Metal or hardwoods should never be cut in orbital action.
To adjust the cutting action, move the cutting action lever (I) between the four cutting
positions: 0, 1, 2, and 3. Position 0 is straight cutting. Positions 1, 2, and 3 are orbital cutting.
The aggressiveness of the cut increase as the lever is adjusted from one to three, with three being
the most aggressive cut.
Adjustment For 90° Cuts
1. The 0° mark on the quadrant plate should line up with mark on shoe.
2. If adjustment is necessary, loosen screw on quadrant plate and adjust as necessary. Place
a right angle against the blade and the shoe and adjust the shoe to 90°.
Anti-Splintering (Fig. 7)
This jig saw has a special double-ended shoe with a wide opening at one end for general
cutting and bevel cutting and a very narrow slot at the other end for use only with hollow
ground blades.This narrow slot acts as an anti-splintering device (J) particularly useful when
cutting plywood.
Reversing Shoe Position (Fig. 7)
To reverse the shoe position remove the screw (H) from the bottom of the tool, as shown in
Figure7, and remove the shoe from the jig saw. [Be careful to note the position of the clamp
(K). This clamp must be re-installed the same way or the shoe will not fit properly.] Turn the shoe
around and re-install noting carefully that, when the slot is forward, the screw goes through the
hole in the shoe and when the wide opening is forward, the screw passes through the slot in
the shoe.
Cutting
WARNING: The jig saw should not be operated with the shoe removed or serious personal
injury may result.
POCKET CUTTING (FIG. 8, 9)
A pocket cut is an easy method of making an inside cut. The saw can be inserted directly into a
panel or board without first drilling a lead or pilot hole. In pocket cutting, measure the surface to
be cut and mark clearly with a pencil. Next tip the saw forward until the front end of the shoe sits
firmly on the work surface and the blade clears the work through its full stroke. Switch the tool on
and allow it to attain maximum speed. Grip the saw firmly and lower the back edge of tool slowly
until the blade reaches its complete depth. Hold the shoe flat against the wood and begin cutting.
Do not remove blade from cut while it is still moving. Blade must come to a complete stop.
WOOD CUTTING
Support the workpiece adequately at all times. Use the higher speed setting for cutting wood.
Do not attempt to turn the tool on when blade is against material to be cut. This could stall the
motor. Place the front of shoe on the material to be cut and hold the jig saw shoe firmly against
the wood while cutting. Don’t force the tool; let the blade cut at its own speed. When the cut is
complete, turn the jig saw off. Let blade come to a complete stop and then lay the saw aside
before loosening the work.
METAL CUTTING
In cutting thin gauge sheet metals, it is best to clamp wood to the bottom of sheet metal; this
will insure a clean cut without the risk of vibration or tearing of metal. Always remember to use a
finer blade for ferrous metals (for those that have a high iron content); and use a coarser blade for
non-ferrous metals (those that do not have an iron content). Use a high speed setting for cutting
soft metals (aluminum, copper, brass, mild steel, galvanized pipe, conduit sheet metal, etc.). Use
lower speed to cut plastics, tile, laminate, hard metals, and cast iron.
MAINTENANCE
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
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.
