Work area safety
Keep work area clean and well lit.
Cluttered or 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 children and bystanders away while
operating a power tool.
Distractions can
cause you to lose control.
Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools.
Unmodified plugs
and matching outlets will reduce risk of
electric shock.
Avoid body contact with earthed or
grounded surfaces such as pipes,
radiators, ranges and refrigerators.
There
is an increased risk of electric shock if your
body is earthed or grounded.
Do not 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
for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil,
sharp edges or moving parts.
Damaged or
entangled cords increase the risk of electric
shock.
When operating a power tool outdoors,
use an extension cord suitable for
outdoor use.
Use of a cord suitable for
outdoor use reduces the risk of electric
shock.
Do not use AC only rated tools with a DC
power supply.
While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a
hazard to the operator.
If operating the power tool in damp
locations is unavoidable a Ground Fault
Circuit Interrupter (GFCI) must be used to
supply the power to your tool.
GFCI and
personal protection devices like electrician’s
rubber gloves and footwear will further
enhance your personal safety.
Personal safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use a power tool while
you are tired or under the influence of
drugs, alcohol or medication.
A moment of
inattention while operating power tools may
result in serious personal injury.
Use safety equipment. Always wear eye
protection.
Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
Avoid accidental starting. Ensure the
switch is in the off-position before
plugging in.
Carrying power tools with your
finger on the switch or plugging in power
tools that have the switch on invites
accidents.
Remove any adjusting key or wrench
before turning the power tool on.
A wrench
or a key left attached to a rotating part of the
power tool may result in personal injury.
Do not overreach. Keep proper footing
and balance at all times.
This enables
better control of the power tool in unexpected
situations.
Dress properly. Do not wear loose
clothing or jewelry. Keep your hair,
clothing and gloves away from moving
parts.
Loose clothes, jewelry or long hair can
be caught in moving parts.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used.
Use of these devices can reduce dust-
related hazards.
Read all instructions. Failure to follow all instructions listed below may
result in electric shock, fire and/or serious injury.
The term “power tool” in
all of the warnings listed below refers to your mains-operated (corded) power tool or batteryoperated (cordless) power tool.

Safety Rules for Jigsaws
Hold power tools 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 handles dry, clean and free from oil
and grease.
Slippery hands cannot safely
c
ontrol the power tool.
Power tool use and care
Do not force the power tool. Use the
correct power tool for your application.
T
he correct power tool will do the job better
and safer at the rate for which it was
designed.
Do not use the power tool if the switch
does not turn it on and off.
Any power tool
that cannot be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any
adjustments, changing accessories, or
storing power tools.
Such preventive safety
measures reduce the risk of starting the
power tool accidentally.
Store idle power tools out of the reach of
children and do not allow persons
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tools operation.
If damaged, have the power tool repaired
before use.
Many accidents are caused by
poorly maintained power tools.
Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
Use the power tool, accessories and tool
bits etc., in accordance with these
instructions and in the manner intended
for the particular type of power tool,
taking into account the working
conditions and the work to be performed.
Use of the power tool for operations different
from those intended could result in a
hazardous situation.
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.
Empty dust container frequently,
especially when sanding wood with
polyurethane, varnish, shellac or similarly
coated surface.
Fine particles of sanding
dust may self ignite and cause fire.
Service
Have your power tool serviced by a
qualified repair person using only identical
replacement parts.
This will ensure that the
safety of the power tool is maintained.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
the tool since internal wires may be
misplaced or pinched or safety guard
return springs may be improperly
mounted.
Certain cleaning agents such as
gasoline, carbon tetrachloride, ammonia, etc.
may damage plastic parts.

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
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.

FOOTPLATE ANGLE ADJUSTMENT
The footplate may be tilted to allow angle cuts
up to 45˚ in either direction. To adjust footplate,
loosen screw with allen wrench, slide the
footplate towards the front of the tool, and
rotate to the desired angle, as marked on the
angle scale (Fig. 5). Detent slots will hold the
footplate firmly at 45˚, and there are additional
position marks for 15˚ and 30˚ angles.
Intermediate angles may be set with a
protractor. After positioning the footplate,
securely tighten screw).
VARIABLE SPEED DIAL
Your Jigsaw is equipped with a variable speed
dial. The blade stroke rate may be adjusted
d
uring cutting operation by presetting the dial
on or between any one of the six numbers.
Setting
1
-2 Low stroke
3-4 Medium stroke
5-6 High stroke
PLUNGER SPEED
The jigsaw cutting speed or stroke rate
required depends on the material being cut, the
type of blade used, and the feed rate preferred
by the operator. The best speed for a particular
application is largely determined by experience,
though as a general rule, slower speeds are for
denser materials and faster speeds for soft
materials. Note that when the jigsaw is used at
low speed settings for any length of time, the
motor temperature will rise due to the slower
speed of the internal cooling fan. In such
cases, it is necessary to occasionally run the
tool at full speed for a few minutes to keep the
motor operating at high efficiency.
BLADE ORBIT
Maximum cutting efficiency can be obtained by
adjusting the blade orbit selector lever to suit
the material being cut. The following chart will
help you determine which setting to use for
your application. This chart is intended as a
guideline only, and test cuts in scrap material
should be performed first to determine the best
setting.
hard materials such as metals
or thin sheet metals and used
with knife blades, grit edge
blades or rasp work
soft materials where cleaner
cutting or delicate scrolling
work is performed
medium density materials
such as harder woods or
particle board
soft materials such as wood,
plastics, etc.
CHIP BLOWER
Your jigsaw is equipped with a two position
chip blower to help keep the cutting line clear
of chips.
By adjusting the chip blower lever the force
of the discharge air may be altered as
follows;
BLOWER SWITCHED ON
For working with wood, plastic
and similar materials that
produce large amounts of
sawdust.
BLOWER SWITCHED OFF
For working with metals and
when cooling agents are used,
or with dust collection accessory.

ANTI-SPLINTER INSERT
To minimize splintering of the top surface of the
m
aterial being cut, place the anti-splinter insert
in the blade opening of the footplate (Fig. 6).
Note: This insert will only work with blades that
have ground sides such as T301CD, T101B,
T101D, and T101DP.
FLUSH CUTTING
To allow the saw to make a perpendicular cut
close to a vertical surface, the footplate may be
repositioned as follows. Remove screw, move
footplate to the front mounting slot, and be sure
t
he detent notch is aligned with the detent slot
in the footplate. Re-insert screw into the
threaded hole closest to the detent notch, and
securely tighten (Fig. 7). Note that when the
footplate is retracted in this manner, only
90˚cuts are possible, and optional cutting guide
may not be used.

Always be certain that smaller workpieces are
securely fastened to a bench or other support.
Larger panels may be held in place by clamps
on a bench or sawhorses.
To begin a cut, clearly mark the cutting line,
and rest the front of the footplate on the work.
Engage the switch, and move the blade into the
work using only enough forward pressure to
keep the blade cutting steadily. DO NOT
FORCE, as this will not make the saw cut
faster; let the blade do the work.
When cutting metal, it is often advisable to use
a lubricant to cool the blade and extend its life.
Choose blades carefully, as the ability of the
jigsaw to follow curves, provides smoother
finishes, or faster cutting is directly related to
the type of blade used.
BLADE SELECTION
• Choose blades carefully, as the ability of the
jigsaw to make the fastest cuts, to follow tight
curves, to achieve the smoothest finish and/or
to maximize the life of the blade are directly
related to the type of blade used.
• Always use a blade that is appropriate for the
cutting task.
• Always make a test cut in a piece of scrap material.
• Most jigsaw blades have upward-pointing
teeth, which helps to pull the jigsaw against the
workpiece and minimizes vibration. Blades with
upward-pointing teeth produce a clean cut on
the bottom of the workpiece.
• Blades with downward-pointing teeth
(reverse-tooth blade) can be used to produce a
clean cut on the top of the workpiece (that side
that faces the jigsaw's footplate), such as when
cutting an already-installed countertop from the
top. When using reverse-tooth blades,
downward force must be applied to the jigsaw.
• Blades with teeth that point straight out (rather
than up or down) allow splinter-free cutting on
both sides of the workpiece. When using such
blades, downward force must be applied to the
jigsaw.
• The following types of blades should only be
used with orbital Setting O:
1. Blades with teeth that point downward
(reverse-tooth blades).
2. Blades with teeth that point straight out
rather than up or down.
3. Carbide-tipped blades.
4. Grit-edge blades.

PLUNGE CUTTING
P
lunge cutting is useful and time-saving in
m
aking 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
cutting line. We do not recommend plunge
cutting with a scroll blade (Fig. 8).
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
c
ut into hard materials such as steel.
FIG. 8
CIRCLE AND PARALLEL CUTTING GUIDE
(Not included, available as accessory)
This accessory is available at an extra cost. It
is used for fast and accurate straight and
circle cutting (Fig.9).
PARALLEL CUTTING
1. Insert bar of guide through lock knob clamp,
then through the slots provided in foot, from
either side of foot with the edge guide facing
DOWN (Fig. 9).
2. Hook lock knob clamp onto edge of
footplate, adjust fence to desired width, and
securely tighten lock knob clamp (Fig. 9).
CIRCLE CUTTING
1. Before attaching the guide, draw a circle
and predrill a 13/64” center hole in workpiece
.
2. Drill or plunge cut near the circles edge,
turn saw off and disconnect the plug from
power source.
3. Attach guide to saw with edge guide facing
UP as shown (Fig. 10).
4. Remove guide pin from end of guide, push
pin through hole provided in guide, then into
center hole of workpiece.
5. Measure the distance from the selected
hole to the blade to be equal to the circle
radius.
6. 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.
