OPERATION
LASER GUIDE
See Figure 6, page ii.
Depress the laser guide switch to generate a red laser
beam on the work surface in front of the saw. Use the
laser to guide the saw along the line of cut.
LOCK-OFF BUTTON
See Figure 7, page ii.
The lock-off button is located on the handle above the
switch trigger. You must depress the lock-off button in
order to pull the switch trigger. The lock resets each time
the trigger is released.
NOTE: You can depress the lock-off button from either the
left or right side.
SWITCH TRIGGER
See Figure 7, page ii.
To turn the saw ON, depress and hold lock-off button,
then depress the switch trigger. To turn it OFF, release the
switch trigger.
GENERAL CUTTING
See Figure 7, page ii.

Rest the front of the saw base on the workpiece and
align cutting edge of the blade with the line on your
workpiece.

Start the saw and move it forward on the work surface.

Apply downward pressure to keep the saw steady
and only enough forward pressure to keep the blade
cutting.
Do not force the saw. Forcing the saw may overheat the
motor and break saw blades. Broken saw blades must be
discarded. Remove the broken portion of the saw blade
from the clamp and install a new saw blade.
WARNING:
Excessive side pressure on the blade
could result in broken blades or damage to the ma-
terial being cut.
ORBITAL MOTION
See Figure 7, page ii.
The blade of the saw cuts in orbital motion. This feature is
adjustable and provides faster, more efficient cutting. The
blade cuts through your work in the upstroke but does not
drag across your work in the downstroke. The higher set-
tings should be used when fast cutting in soft material is
desired. The lower settings should be used when cutting
materials with more resistance.
STRAIGHT CUT
See Figure 7, page ii.
A straight cut can be made by clamping a piece of wood
or straightedge to the workpiece and guiding the edge of
the saw against it. Make the cut from one direction only.
Do not cut halfway and complete the cut from the oppo-
site end.
SCROLL CUTTING
See Figure 8, page ii.
Scroll cuts can be made with the jig saw by guiding the
direction of the cut with applied pressure on the handle.
ANGLE CUTTING (BEVEL CUTTING)
See Figures 9 - 10, page ii.
Bevel cutting angles may be adjusted from 0° to 45° right
or left. Angles for cuts from 0° to 45° in 15° increments
are marked on a scale on both the left and right side of
the base. Notches on the rear of the base provide posi-
tive stops at each of the above mentioned 15° increments.
A protractor is recommended when accurate cuts are
required.


Remove the battery pack.


Using the 1/8 in. hex key provided, loosen the base
pivot screws until the base can be moved.


Slide base forward until base pivot screws can move
freely in slots in base.


Align the mark, on the base, of the desired angle with
the edge of the motor housing.


Once the desired angle is reached, slide base back
until tab on motor housing aligns with the appropriate
notch on rear of base.
NOTE: When making a set-up for accurate cuts with
a protractor, or for angles other than the preset 15°
increments, the positive stop notches on the rear of the
base are not used.


Tighten the base pivot screws securely.


Return hex key to storage compartment.


Replace the battery pack.
NOTE: The wide slot in the base must be used when mak-
ing bevel cuts, scroll cuts, plunge cuts, and when cutting
metal.
PLUNGE CUTTING
See Figures 11 - 12, page ii.
WARNING:
To avoid loss of control, broken blades,
or damage to the material being cut, always use
extreme caution when making plunge cuts. We do
not recommend plunge cutting on materials other
than wood.
TO MAKE A PLUNGE CUT
 Mark the line of cut clearly on the workpiece.


Set the cutting angle at 0° and the orbital adjustment
knob to 0.
  Drill a pilot hole though any point on the line of cut.


Using high speed, start the saw and slowly lower the
blade through the pilot hole into the workpiece until the
blade cuts through the wood.
 Do not move the base forward until the blade cuts
entirely through the workpiece and the base is in
complete contact with the workpiece.
