Motor
Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than
10% will cause loss of power and overheating. 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. D
tested; if this tool does not operate, check power supply.
COMPONENTS
A. Trigger switch
B. Lock button
C. Speed control dial
D. Blade lever
E. Bevel lever
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 on speed A to approximately 3,100 SPM on speed F.
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.

ASSEMBLY AND ADJUSTMENTS

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.
Blade Installation and Removal (Fig. 3)
CAUTION: Turn off and unplug the tool before making any adjustments or removing/
installing attachments or accessories.
TO INSTALL A BLADE
NOTE: This jig saw uses only T-shank jig saw blades.
NOTE: The DT2074 flush cutting blade is for use with D
NOTE: When installing flush cutting blades (DT2074), the anti-splinter insert must be removed and
the shoe must to be in the 0° positive stop position.
1. Lift the keyless blade lever (D).
2. Insert the T-shank blade into the clamp mechanism (K) while guiding the back of the blade into
the groove of the guide rollers (L).
3. The T-shank should be completely inside the clamp mechanism as shown in Figure 3.
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.
Beveling the Shoe (Fig. 4)
To unlock the shoe, pull the keyless bevel lever (E) to the side.
To lock the shoe, push the keyless bevel lever back under the body of the jig saw.
TO BEVEL THE SHOE
1. Unlock the shoe.
2. Slide the shoe (F) forward to release it from the 0° positive stop position.
3. The shoe can be beveled to the left or to the right and has detents at 15°, 30° and 45°. The
shoe can be manually stopped at any degree between 0° and 45°.
4. Once the desired bevel angle is achieved, lock the shoe into place.
TO SET SHOE BACK TO 0°
1. Unlock the shoe.
2. Rotate the shoe back to 0°.
3. Slide the shoe back into the 0° positive stop position.
4. Lock the shoe.

Cutting Action – Orbital or Straight (Fig. 5)
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 less smooth 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 (G) 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.
Dust Blower (Fig. 6)
The dust blower helps clear the cutting area of debris created from the blade.
NOTE: When cutting metal, turn the dust blower off so cutting fluids are not blown away from the
blade.
To turn the dust blower on, slide the dust blower control (H) all the way to the top.
To turn the dust blower off, slide the dust blower control all the way to the bottom.
Removable No-Mar Shoe Cover (Fig. 7)
The no-mar shoe cover (I) should be used when cutting surfaces that scratch easily, such as
laminate, veneer, or paint.
To attach no-mar shoe cover, place the front of the aluminum shoe (F) into the front of the
no-mar shoe cover (I) and lower the jig saw. The no-mar shoe will click securely onto the rear of
aluminum shoe.
To remove no-mar shoe cover, grasp the no-mar shoe cover from the bottom; holding onto the
two rear tabs (M) remove the no-mar shoe cover.
Anti-Splinter Insert (Fig. 8)
NOTE: Do not use the anti-splinter insert with the flush cutting blade.
The anti-splinter insert (J) should be used when trying to minimize tear-out, especially when cutting
veneer, laminate, or finished surfaces, such as paint. The anti-splinter insert should be installed into
the no-mar shoe cover (I). If the no-mar cover is not used, install anti-splinter insert into shoe (F).
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.
Cutting
WARNING: The jig saw should not be operated with the shoe removed or serious personal
injury may result.
