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 a n y adapter plu g s 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.
If operating the power tool in damp locations
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of
an GFCI reduce the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and
us e common sense when ope ratin g 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 personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the
sw itch is in the off-positi on b efore
connecting to power source and / or battery
pa ck, pick ing up or c arrying the tool.
Carrying power tools with your finger on the
switch or energizing 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
con trol o f the power tool in une xpected
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 dust collection can reduce dust-
related hazards.
Power tool use and care
Do not force the power tool. Use the correct
power tool for your application. The 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
can n ot be control l ed with the switc h is
dangerous and must be repaired.
Read all safety warnings and instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.

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 tool’s operation. If damaged,
have the power tool repaired before use.
Man y acci d ents are c aused by p o orly
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.

Safety Rules for Jigsaws
Hol d powe r powe r tool by insulate d
gripping surfaces, when performing an
operation where the cutting accessory
may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool
"live" and could give the operator an electric
shock.
Use clamps or another practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or
against your body leaves it unstable and may
lead to loss of control.
Do not drill, fasten or break into existing
walls or other blind areas where electrical
wiring ma y exist. If this si t u ation is
unavoidable, disconnect all fuses or circuit
breakers feeding this worksite.
Nev e r leave t he trigge r 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 an d s a w blade h o l d e r . 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 gog g l e s o r e y e
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
prot e c t i v e gloves w h e n grasping t h e
blade or accessory. Accessories may be
hot after prolonged use.
If your tool is equipped with a dust bag,
empty it fre quently and after completion of
sawing. Spontaneous combustion, may in
time, result from mixture of oil or water with dust
particles. Be ex tremely careful of dust disposal,
materials in fine particle form may be explosive.
Do not throw contents on an open fire.
Additional Safety Warnings
GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.
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.
Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
th e tool since int ernal 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.
Risk of injury to user. The power cord must only
be serviced by a Bosch Factory Service Center
or Autho rized Bosch Service Station.
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.
You r r isk from these exposur e s 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.

Assembly
BLADE INSTALLATION AND REMOVAL
This jigsaw is equipped with the tool-less blade
changing system. This system makes
changing blades simple and fast.
Insert the saw blade (teeth in cutting direction)
until it latches in the plunger (Fig. 2.) When
inserting the saw blade, the back of the blade
must rest in the groove of the guide roller. To
prevent damage to tool, do not manually turn
blade ejector lever when inserting the blade
To change the saw blade, push the ejector
lever to the center stop; this releases and
ejects the saw blade (Fig. 3).
When changing the blade, tool should be held
so that the blade is safely ejected.
To prevent damage to tool, do
not manually turn blade
ejector lever when there is no blade in the
plunger or when inserting the blade.
If the two fingers inside the plunge r
accidentally get pushed into the plunger, they
will prevent insertion of a blade. To bring the
fingers back to their correction positions, turn
the blade ejector lever in the direction of the
arrow. The fingers will snap into the correct
open position (Fig. 4).
BLADE CLAMP RESET
Step 1 - Push down on blade clamp fingers
until blade clamp can be rotated in direction
indicated by arrow.
Step 2 - Rotate blade clamp lever until it
locks into place.
The blade clamp is now ready again for use.
VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Your tool is equipped with a variable speed trigger
switch. The tool can be turned "ON" or "OFF" by
squeezing or releasing the trigger. The speed can
be adjusted from the minimum to maximum RPM
as set on the variable speed dial by the pressure
you apply to the trigger. Apply more pressure to
increase the speed and release pressure to
decrease speed.
"LOCK-ON" BUTTON
The "Lock-ON" button, located in the handle of
your tool allows for continuous operation at
maximum RPM without holding the trigger.
TO LOCK TRIGGER "ON": squeeze trigger,
depress button and release trigger.
TO UNLOCK THE TRIGGER: squeeze trigger
and release it without depressing the "LockON" button.
If the “Lock-ON” button is
continuously being depressed,
the trigger can not be released.

FOOTPLATE ANGLE ADJUSTMENT
The footplate may be tilted to allow angle cuts
up to 45˚ in either direction. To adjust footplate,
loosen screw with 5 mm allen wrench, slide the
footplate towards the back 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).
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.
0 hard materials such as metals or thin
sheet metals and usedwith knife blades,
grit edge blades or rasp work
I soft materials where cleaner cutting or
delicate scrolling work is performed
II medium density materials such as harder
woods or particle board
III soft materials such as wood, plastics,
etc.
CHIP BLOWER
Your jigsaw is equipped with an always-on
blower to help keep the cutting line clear of
chips.

Tool Tips
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.

ANTI-SPLINTER INSERT
To minimize splintering of the top surface of the
material 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.

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 bl ade. W hen 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. 7).
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.
FIG. 7
Service
Pr event ive maintenance
performed by unauthorized
per so n nel may result in misplacing of
internal wire s an d co mponents which
could c ause s e r ious h a z a rd. We
recommend that all tool service be performed
by a Bosch Factory Service Center or Autho rized Bosch Service Station.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready to use. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.
CARBON BRUSHES
The brushes and commutator in your tool
have been engineered for many hours of
dependable s e r vice. To main t a i n peak
efficiency of the motor, we recommend every
two to six months the brush es be examined.
Only genuine Bosch replace ment brushes
specially designed for your tool should be
used.
BEARINGS
Bearings which become noisy (due to heavy
load or very abrasive material cut ting) should
be replaced at once to avoid overheating or
motor failure.
Cleaning
To avoid accidents always
dis connect the tool from
the p o w e r supply before cleaning o r
performing any main tenance. The tool may
be cleaned most effectively with compressed
dry air. Always wear safety gog gles when
cleaning tools with compressed air.
