VARIABLE SPEED
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.
The lock button (D) should be depressed whenever the tool is not in
use to eliminate the chance of accidental starting (Fig. 6).

Blade Installation and Removal
CAUTION: Turn off tool and remove battery 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
only.
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 (E) as shown in Figure 7.
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 7.
4. Release the keyless blade lever.
TO REMOVE A BLADE
1. Lift the keyless blade lever (E).
2. With a slight shake the blade will drop out.
CAUTION: Do not touch used blades, they may be hot. Personal injury may result.

Cutting Action – Orbital or Straight (Fig. 9)
This jig saw is equipped 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 (H) between the four cutting
positions: 0, 1, 2, and 3. Position 0 is straight cutting. Positions 1, 2, and 3 are orbital cut-
ting. 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. 10)
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 (I) all the way to
the top.
To turn the dust blower off, slide the dust blower control all the way to the bottom.
Removeable No-Mar Shoe Cover
The no-mar shoe cover (J) 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 (G) into the front
of the no-mar shoe cover (J) and lower the jig saw. The no-mar shoe will click secure-
ly onto the rear of aluminum shoe (Fig. 11).
