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 Ren_oval _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 DEWALT DW331 and DC330 jig saws
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 (D).
2. Insert the T-shank blade into the clamp mechanism (K) whila 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 keyiess blade lever.
TO REMOVE A BLADE
1 Lift the keyless blade level (D).
2 With a Might shake the blade will drop out.
_CAUTION: Do not touch used blade& they may be hot. Persona! injury rr_y t_sult,
BeveHreg the SJ_oe fFJg. 4)
To unlock the shoo, pull the keylass bevel lever (E) to the side.
To lock the shoo, push the keyJess 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 ol 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
Cuttireg ActiOn - Orbital or StraLqht (Fig. 5)
htkCAUTION: Check that tire tool is fret lecked ON before corrnect#rg it to a power supply, If tire

a_l_ Damage to your tool or personal irrjury nray result:
This jig saw is equipped with four cutting actions three orbital and or_e straight. Orbital action
has a more agglessive 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 hardwoc_Js should never be cut in orbital action.
To adjust the cutting action, move the cutting action [ever (G) between the four cutting pesi-
tk)ns: 0, 1, 2, and 3, Position 0 is straight cuttin9_ Positions !, 2, and 3 are orbital cutting, T'he
aggressiveness of the cut increase as the lever is adiusted from one to three, with three being
the most aggressive cut.
Dusft Blower fFig. 6)
The dust blowel helps clear the cutting area oI 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
Ren_ovable No-Mar Shoe Cover (Fig. 7)
_f're no-mar shoe cover (I) should be used when cutting surlaces that scratch easily, such as
laminate, veneer, or paint.
To attach no-mar shoo 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.
AretJ-Splinter Iresert (Fig= 8)
NOTE: Do not use the anti-splinter insert with the flush cuttirlg btade.
The arrti-splinter insert (J) should be used when trying to minimize tear-out, especially when cut-
ting veneel, laminate, or finished surfacee, such as paint. The anti-splinter insert should be
installed into the no-mar shoe cover (I) If the nomar cover is not used, install antFsplinter insert
into shoe (F).

Cutting
A WARNING: The j_g saw should not be operated with the shoe removed or serious personal
injt#y may result.
POCKET CUTTING (FIG, 10}
A pocket cut is an easy method of making an inside cut. The saw can be inserted directly into a
pane! or _ard without first drilling a lead or pilot hole, In pocket cutting, measure the sudace to be
cut and mark clearly with a pencil Nexl tip the saw forward until the front end oH the shoe sits firmly
on the work surface arrd the blade clears the work through its full stroke. Sw_ch the t(×_f on and
aIIow it to altain rnaximurr} speed. Grip the saw firmly and lower the back _dge of tool slowly until
the blade roaches its complete depth. Hold the shoe flat against the weod and begin cutting. Do
not remove blade from cut whila it is still moving. Blade must come to a complete stop.
FLUSH CUTTING (FIG, 9)
A flush cut is necessary when finishing off cuts up to a wall or an ob.stacle, such as back-splash
One of the easiest ways to accomplish the flush cut is to u_ a flush cutting blade (DT2074). The
flush cutting blade provides the reach necessary to cuff right up to the front edge of the jig saw
shoe. Remove the anti-splinter insert and return the shoe to the 0 ° positive stop position before
installing and using the flush cutting blade. For the best cut quality the flush cutting blade should
be used [n the 0 or I orbital position, The flush cutting blade should net be used to start the cut
because the f_ush cutting blade prevents the shoe flom being supported by the work surface.
Use wood cutting practices explained below.
WOOD CUTTING
Sup_x>rt 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 stal! 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 too!: let the blade cut at its own speed. When the cut is
complete, turn the jig saw off, Let blade come to a comp}ete 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 wit!
insure a clean cut without the risk of vibration or tearing of metal. Always r÷member to use a finer
blade for ferrous metals (k)r those that have a high iron content); and use a coarser blade for non-
ferreus 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_
C_ean_reg
CAUTION: Never use solvents or othe_ harsh chemicals fer cleaning the non-metallk: 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.
Do not use gasoline, turpentine, lacquer or paint thinner dry cleaning fluids or similar products.
Never let any liquid get inside the tool; never immerse any part oH the too{ into a liquid
