Work Area
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
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.
Keep by-standers, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Double Insulated tools are equipped with a
polarized plug (one blade is wider than the
other.) This plug will fit in a polarized outlet
only one way. If the plug does not fit fully
in the outlet, reverse the plug. If it still does
not fit, contact a qualified electrician to
install a polarized outlet. Do not change the
plug in any way. Double Insulation
eliminates the need for the three wire
grounded power cord and grounded power
supply system. Before plugging in the tool, be
certain the outlet voltage supplied is within the
voltage marked on the nameplate. Do not use
“AC only” rated tools with a DC power supply.
Avoid body contact with grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is grounded. If
operating the power tool in damp locations is
unavoidable, a Ground Fault Circuit Interrupter
must be used to supply the power to your
tool. Electrician’s rubber gloves and footwear
will further enhance your personal safety.
Don't expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord
to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil,
sharp edges or moving parts. Replace
damaged cords immediately. Damaged
cords increase the risk of electric shock.
When operating a power tool outside, use
an outdoor extension cord marked "W-A"
or "W." These cords are rated for outdoor use
and reduce the risk of electric shock. Refer to
“Recommended sizes of Extension Cords” in
the Accessory section of this manual.
Personal Safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose clothing
or jewelry. Contain long hair. Keep your
hair, clothing, and gloves away from
moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts. Keep
handles dry, clean and free from oil and
grease.
Avoid accidental starting. Be sure switch
is “OFF” before plugging in. Carrying tools
with your finger on the switch or plugging in
tools that have the switch “ON” invites
accidents.
Remove adjusting keys or wrenches before
turning the tool “ON”. A wrench or a key
that is left attached to a rotating part of the
tool may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. Proper footing and
balance enables better control of the tool in
unexpected situations.
Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must be
used for appropriate conditions.
Tool Use and Care
Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or
against your body is unstable and may lead to
loss of control.
Do not force tool. Use the correct tool for
your application. The correct tool will do the
job better and safer at the rate for which it is
designed.Do not use tool if switch does not

Safety Rules for Jigsaws
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or
its own cord. Contact with a "live" wire will
make exposed metal parts of the tool "live"
and shock the operator. Do not drill, fasten
or break into existing walls or other blind
areas where electrical wiring may exist. If
this situation is unavoidable, disconnect all
fuses or circuit breakers feeding this
worksite.
Never leave the trigger locked "ON".
Before plugging the tool in, check that the
trigger lock is "OFF". Accidental start-ups
could cause injury.
Be aware of the location and setting of
the switch "Lock-ON" button. If the switch
is locked "ON" during the use, be ready for
emergency situations to switch it "OFF", by
first pulling the trigger then immediately
releasing it without pressing the "Lock-ON"
button.
Keep hands away from cutting area. Do
not reach under the material being cut.
The proximity of the blade to your hand is
hidden from your sight.
Keep hands from between the gear
housing and saw blade holder. The
reciprocating blade holder can pinch your
fingers.
Do not use dull or damaged blades. Bent
blade can break easily or cause kickback.
Before starting to cut, turn tool "ON" and
allow the blade to come to full speed.
Tool can chatter or vibrate if blade speed is
too slow at beginning of cut and possibly
kickback.
Always wear safety goggles or eye
protection when using this tool. Use a
dust mask or respirator for applications
which generate dust.
Secure material before cutting. Never
hold it in your hand or across legs. Small
turn it “ON” or “OFF”. Any tool that cannot
be controlled with the switch is dangerous
and must be repaired.
Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing the tool. Such
preventive safety measures reduce the risk of
starting the tool accidentally.
Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools, with sharp cutting edges are less likely
to bind and are easier to control. Any
alteration or modification is a misuse and
may result in a dangerous condition.
Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools. Develop
a periodic maintenance schedule for your
tool.
Use only accessories that are
recommended by the manufacturer for
your model. Accessories that may be
suitable for one tool, may become
hazardous when used on another tool.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury. For
example: internal wires may be misplaced or
pinched, safety guard return springs may be
improperly mounted.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk
of electric shock or injury. Certain cleaning
agents such as gasoline, carbon
tetrachloride, ammonia, etc. may damage
plastic parts.

or thin material may flex or vibrate with the
blade, causing loss of control.
Make certain all adjusting screws and the
blade holder are tight before making a
cut. Loose adjusting screws and holders
can cause the tool or blade to slip and loss
of control may result.
When removing the blade from the tool
avoid contact with skin and use proper
protective gloves when grasping the
blade or accessory. Accessories may be
hot after prolonged use.
If your tool is equipped with a dust bag,
empty it frequently and after completion of
sawing. Spontaneous combustion, may in
time, result from mixture of oil or water with
dust particles. Be extremely careful of dust
disposal, materials in fine particle form may be
explosive. Do not throw contents on an open
fire.
Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement
and other masonry products, and
• Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.

Operating Instructions
Face the good side of the material down and
secure it in a bench vise or clamp it down.
Draw cutting lines or designs on the side of
the material facing up towards you. Then
place the front edge of the saw foot on the
work and line up the blade with the line to be
cut. Hold the jigsaw firmly, turn it on, and
press down (to keep the saw foot flat against
the work) as you slowly push the saw in the
direction of the cut.
Build up cutting rate gradually, cutting close
to the line (unless you want to leave stock for
finish sanding). As you cut you may have to
adjust or relocate the vise or clamps to keep
the work stable. do not force the saw or he
blade teeth may rub and wear without cutting
and the blade may break. Let the saw do
most of the work. When following curves, cut
slowly so the blade can cut through cross
grain. This will give you an accurate cut and
will prevent the blade from wandering.
REDUCED-SPLINTER CUTTING
Reduced-splinter cutting is used when
cutting through plywood or a similar material.
The foot must be horizontal 0˚ (Fig. 3), and the
use of a hollow ground or smooth cutting
blade is recommended during reducedsplinter cutting.

PLUNGE CUTTING
Plunge cutting is useful and time-saving in
making rough openings in softer materials. It
is not necessary to drill a hole for an inside or
pocket cut. Draw lines for the opening, hold
the saw firmly, tilt it forward so that the toe of
the saw foot rests on the work, but with the
blade well clear of the work. Start the motor,
and then very gradually lower the blade.
When it touches, continue pressing down on
the toe of the saw foot slowly pivoting the
saw like a hinge until the blade cuts through
and the foot rests flat on the work. Then saw
ahead on the line of cut. We do not
recommend plunge cutting with a scroll blade
(Fig. 5).
To make sharp corners, cut up to the corner,
then back up slightly before rounding the
corner. After the opening is complete, go
back to each corner and cut it from the
opposite direction to square it off. Do not try
to plunge cut into hard materials such as
steel.
Always disconnect the plug from power
source before making adjustments. Your saw
has an adjustable foot for doing reduced
splinter cutting. To adjust: loosen the foot
adjustment screw in the bottom of foot with a
flat tip screwdriver, and slide the foot forward
so the slot in foot surrounds the blade on
both sides and securely tighten foot
adjustment screw.
The foot must be moved
backward when using the
bevel adjustment, or any other blade than
hollow or smooth cutting blades.
If finished materials must be cut face up, use
splinter free setting and reverse tooth blade
available at your dealer. Note: Do not use the
blade provided with your jigsaw during
reduced cutting since it is not hollow ground
or smooth cutting blade. These blades can be
purchased from your dealer.
BLADE STORAGE COMPARTMENT
Your saw is equipped with a blade storage
area (Fig. 3) on the backside of your saw. To
open, slide door up in direction of arrow. To
close, slide slide door in opposite direction.
Be sure door is closed to prevent blades from
falling out.
CUTTING WITH A STRAIGHTEDGE
Always use a rough-cut blade when possible.
Clamp a straightedge on the work parallel to
the line of cut and flush with the side of the
saw foot. (Either first mark the line of cut and
then position the straightedge parallel and at
the same distance as between the blade and
the side edge of the foot, or first mark the
side edge of the foot and then clamp the
straightedge on the mark and parallel to the
line of cut Fig. 4)
As you cut, keep the saw foot edge flush
against the straightedge and flat on th work
(Fig. 4).

METAL CUTTING
When cutting metal clamp material down. Be
extra certain that you move the saw along
slowly. Use lower speeds. Do not twist, bend,
or force the blade. If the saw jumps or
bounces, use a blade with finer teeth. If the
blade seems clogged when cutting soft
metal, use a blade with coarser teeth.
For easier cutting, lubricate the blade with a
stick of cutting wax, if available, or with
kerosene when cutting aluminum or cutting
oil when cutting steel. Thin metal should be
sandwiched between two pieces of wood or
tightly clamped on a single piece of wood
(wood on top of the metal). Draw the cut lines
or design on the top piece of wood.
When cutting aluminum extrusion or angle
iron, clamp the work in a bench vise and saw
close to the vise jaws.
When sawing tubing and the diameter is
larger than the blade is deep, cut through the
wall of the tubing and then insert the blade
into the cut rotating the tube as you saw.
RIP FENCE AND CIRCLE CUTTING GUIDE
This accessory is available at an extra cost. It
is used for fast and accurate straight and
circle cutting (Fig. 7a & 7b).
ATTACHING RIP FENCE
1. Insert bar of rip fence through the slots
provided in foot, from either side of foot with
the edge guide facing down (Fig. 7a & 7b).

STRAIGHT CUTTING
Once the rip fence is attached, measure from
the edge of work to the line of cut, and set
edge guide of rip fence to the same distance
and then securely tighten clamp screw (Fig. 8).
CIRCLE CUTTING
1. Before attaching the rip fence, draw a
circle and drive a finishing nail in the center of
circle.
2. Drill or plunge cut near the circles edge,
turn saw off and disconnect the plug from
power source (Fig. 10).
3. Attach rip fence to saw with the edge guide
facing UP. In order for the rip fence to cut a
circle, the nail must be in alignment with the
blade, as shown in (Fig. 9).
4. Measure the distance from the selected
hole to the blade to be equal to the circle
radius.
5. Insert plug into power source, hold the saw
firmly, squeeze trigger and slowly push the
saw forward. To make a hole, cut from inside
the circle; To make wheels or discs, cut from
the outside.
Cutting Tip: Cut slowly so the blade will stay
straight in the cut. Place small wedges in the
cut as shown in Fig. 10, to keep the inner
circle from spreading when near the end of
the cut.
