Safety Notes
General Power Tool Safety Warnings
Read all safety warnings and all
instructions. Failure to follow
the warnings and instructions may result in elec-
tric 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.
1) Work area safety
a) Keep work area clean and well lit. Clut-
tered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away
while operating a power tool. Distrac-
tions can cause you to lose control.
2) Electrical safety
a) 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.
b) Avoid body contact with earthed or
grounded surfaces, such as pipes, radia-
tors, ranges and refrigerators. There is
an increased risk of electric shock if your
body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
d) 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 and moving parts.
Damaged or entangled cords increase the
risk of electric shock.
e) When operating a power tool outdoors,
use an extension cord suitable for out-
door use. Use of a cord suitable for out-
door use reduces the risk of electric
shock.
f) If operating a power tool in a damp loca-
tion is unavoidable, use a residual cur-
rent device (RCD) protected supply. Use
of an RCD reduces the risk of electric
shock.
3) Personal safety
a) 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 influ-
ence of drugs, alcohol or medication. A
moment of inattention while operating
power tools may result in serious person-
al injury.
b) Use personal protective equipment. Al-
ways wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protec-
tion used for appropriate conditions will
reduce personal injuries.
c) Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and/or bat-
tery pack, picking up or carrying the
tool. Carrying power tools with your fin-
ger on the switch or energising power
tools that have the switch on invites acci-
dents.
d) Remove any adjusting key or wrench be-
fore turning the power tool on. A wrench
or a key left attached to a rotating part of
the power tool may result in personal inju-
ry.
e) Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in unex-
pected situations.
f) Dress properly. Do not wear loose cloth-
ing or jewellery. Keep your hair, clothing
and gloves away from moving parts.
Loose clothes, jewellery or long hair can
be caught in moving parts.

Bosch Power Tools 1 609 929 S83 | (1.7.09)
g) If devices are provided for the connec-
tion of dust extraction and collection fa-
cilities, ensure these are connected and
properly used. Use of dust collection can
reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the cor-
rect power tool for your application. The
correct power tool will do the job better
and safer at the rate for which it was de-
signed.
b) 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 re-
paired.
c) Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjust-
ments, changing accessories, or storing
power tools. Such preventive safety
measures reduce the risk of starting the
power tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfa-
miliar with the power tool or these in-
structions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for mis-
alignment or binding of moving parts,
breakage of parts and any other condi-
tion that may affect the power tool’s op-
eration. If damaged, have the power tool
repaired before use. Many accidents are
caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Prop-
erly maintained cutting tools with sharp
cutting edges are less likely to bind and
are easier to control.
g) Use the power tool, accessories and tool
bits etc. in accordance with these in-
structions, taking into account the work-
ing conditions and the work to be per-
formed. Use of the power tool for
operations different from those intended
could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qual-
ified repair person using only identical
replacement parts. This will ensure that
the safety of the power tool is maintained.
Safety Warnings for Jigsaws
fHold power tool by insulated gripping sur-
faces, 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.
fKeep hands away from the sawing range.
Do not reach under the workpiece. Contact
with the saw blade can lead to injuries.
fApply the machine to the workpiece only
when switched on. Otherwise there is dan-
ger of kickback when the cutting tool jams in
the workpiece.
fPay attention that the base plate 7 rests se-
curely on the material while sawing. A
jammed saw blade can break or lead to kick-
back.
fWhen the cut is completed, switch off the
machine and then pull the saw blade out of
the cut only after it has come to a standstill.
In this manner you can avoid kickback and
can place down the machine securely.
fUse only sharp, flawless saw blades. Bent or
unsharp saw blades can break or cause kick-
back.
fDo not brake the saw blade to a stop by ap-
plying side pressure after switching off. The
saw blade can be damaged, break or cause
kickback.
fUse suitable detectors to determine if utili-
ty lines are hidden in the work area or call
the local utility company for assistance.
Contact with electric lines can lead to fire
and electric shock. Damaging a gas line can
lead to explosion. Penetrating a water line
causes property damage or may cause an
electric shock.

1 609 929 S83 | (1.7.09) Bosch Power Tools
fSecure the workpiece. A workpiece clamped
with clamping devices or in a vice is held
more secure than by hand.
fKeep your workplace clean. Blends of mate-
rials are particularly dangerous. Dust from
light alloys can burn or explode.
fAlways wait until the machine has come to
a complete stop before placing it down. The
tool insert can jam and lead to loss of control
over the power tool.
fNever use the machine with a damaged ca-
ble. Do not touch the damaged cable and
pull the mains plug when the cable is dam-
aged while working. Damaged cables in-
crease the risk of an electric shock.

rod 10. Briefly press the SDS clamping lever 15
toward the side and release it again.
fCheck the tight seating of the saw blade. A
loose saw blade can fall out and lead to inju-
ries.
Ejecting the Saw Blade (see figure B)
fWhen ejecting the saw blade, hold the ma-
chine in such a manner that no persons or
animals can be injured by the ejected saw
blade.
Press the SDS clamping lever 15 sideward to
the stop. The saw blade 12 is released and eject-
ed.
Dust/Chip Extraction
fDusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Dust Cover
Mount the dust cover 14 before connecting the
machine to the dust extraction.
Mount the dust cover 14 onto the machine in
such a manner that the holders in the centre of
the dust cover engage on the contact protector
13.
For work without dust extraction, the dust cover
14 can be removed. To remove the dust cover
14, grasp it by the side and pull it off toward the
front.
Connecting the Dust Extraction
(see figures C–E)
Mount the vacuum connection 5into the open-
ing of the base plate 7. Make sure that the plas-
tic tip of the vacuum connection engages into
the corresponding opening on the housing as
shown in the figure.
Depending on the machine model, place a vacu-
um hose 17 (accessory) either directly onto the
vacuum connection 5or cut off the old hose
end, screw the extraction adapter 18 (accesso-
ry) onto the hose end and insert it directly into
the vacuum connection 5. Connect the vacuum
hose 17 with a vacuum cleaner (accessory). An
overview for the connection of various vacuum
cleaners can be found at the end of these in-
structions.
Switch the saw dust blower off when a dust ex-
traction system is connected (see “Sawdust
Blower Device”).
To enable optimum dust extraction, use the
splinter guard 19 if possible.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Splinter Guard (see figure F)
The splinter guard 19 (accessory) can prevent
fraying of the surface while sawing wood. The
splinter guard can only be used for certain saw
blade types and only for cutting angles of 0°.
When sawing with the splinter guard, the base
plate 7must not be moved back for cuts that are
close to the edge.
Press the splinter guard 19 from below into the
base plate 7(with the notch facing upward as
shown in the figure).

Bosch Power Tools 1 609 929 S83 | (1.7.09)
The splinter guard 19 can be inserted into the
base plate in 2 positions. For narrow saw
blades, insert the splinter guard fully to the
front; for wider saw blades, insert it further to
the rear in the base plate 7.
When using the sliding shoe 6, the splinter
guard 19 is not inserted into the base plate 7,
but into the sliding shoe.
Sliding Shoe
When working surfaces that are easily
scratched, the sliding shoe 6can be attached
onto the base plate 7in order to prevent the sur-
face from being scratched.
To attach the sliding shoe 6, insert it at the front
of the base plate 7, push the rear part upward
and allow it to latch.
Operation
Operating Modes
fBefore any work on the machine itself, pull
the mains plug.
Orbital Action Settings
The four orbital action settings allow for optimal
adaptation of cutting speed, cutting capacity
and cutting pattern to the material being sawed.
The orbital action can be adjusted with the ad-
justing lever 9, even during operation.
The optimal orbital action setting for the respec-
tive application can be determined through
practical testing. The following recommenda-
tions apply:
– Select a lower orbital action setting (or
switch it off) for a finer and cleaner cutting
edge.
– For thin materials such as sheet metal,
switch the orbital action off.
– For hard materials such as steel, work with
low orbital action.
– For soft materials and when sawing in the di-
rection of the grain, work with maximum or-
bital action.
Adjusting the Cutting Angle (see figure G)
The base plate 7can be swivelled by 45° to the
left or right for mitre cuts.
– Remove the dust cover 14 and the vacuum
connection 5.
– Release the clamping lever 22 of the base
plate and lightly push the base plate 7to-
ward the mains cable.
– For adjustment of precise mitre angles, the
base plate has adjustment notches on the
left and right at 0° and 45°. Swivel the base
plate 7to the desired position according to
the scale 20. Other mitre angles can be ad-
justed using a protractor.
– Afterwards, push the base plate 7to the stop
in the direction of the saw blade 12.
– Close the base plate clamping lever 22 to
lock the base plate in the adjusted position.
The dust cover 14, vacuum connection 5and
splinter guard 19 cannot be used for mitre cuts.
Offsetting the Base Plate (see figure H)
For sawing close to edges, the base plate 7can
be offset to the rear.
– Remove the dust cover 14 (see “Dust Cover”,
page 10).
– Release the clamping lever 22 of the base
plate and push the base plate 7toward the
mains cable to the stop.
– Close the base plate clamping lever 22 to
lock the base plate in the adjusted position.
Sawing with the base plate 7offset is possible
only with a mitre angle of 0°. In addition, the
parallel guide with circle cutter 25 (accessory)
as well as the splinter guard 19 may not be used.
Changing the Pre-tension of the Base Plate
With the thumbwheel 21, the pre-tension of the
base plate clamping lever 22 can be changed.
When the base plate 7is not seated tightly after
closing the lever, open the clamping lever and
turn the thumbwheel for pre-tension of the base
plate in the “+” direction.
Setting 0 No orbital action
Setting I Small orbital action
Setting II Medium orbital action

1 609 929 S83 | (1.7.09) Bosch Power Tools
When the base plate cannot be adjusted or only
with difficulty after opening the clamping lever,
turn the thumbwheel in the “–” direction.
Sawdust Blower Device
With the air jet of the sawdust blower device 8,
the cutting line can be kept free of dust and
chips.
Switching on the sawdust blower device: For
cuts in materials with high removal rate, such as
in wood, plastic, etc., push the switch 8to posi-
tion “I”.
Switching off the sawdust blower device: For
cuts in metal and when a dust extraction system
is connected, push the switch 8to position “0”.
Starting Operation
fObserve correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off (GST 120 E)
To start the power tool, push the On/Off switch
3forwards.
To switch off the machine, push the On/Off
switch 3toward the rear so that the “0” is indi-
cated on the switch.
Switching On and Off (GST 120 BE)
To start the machine, press the On/Off switch 3
and keep it pressed.
To lock the pressed On/Off switch 3, press the
lock-on button 2.
To switch off the machine, release the On/Off
switch 3. When the On/Off switch 3is locked,
press it first and then release it.
Controling the Stroke Rate (GST 120 BE)
Increasing or reducing the pressure on the
On/Off switch 3enables stepless stroke-rate
control of the switched-on machine.
Light pressure on the On/Off switch 3results in
a low stroke rate. Increasing the pressure also
increases the stroke rate.
When the On/Off switch 3is locked, it is not
possible to reduce the stroke rate.
Presetting the Stroke Rate
With the thumbwheel for stroke rate preselec-
tion 4, the stroke rate can be preset and
changed during operation.
The required stroke rate is dependent on the
material and the working conditions and can be
determined by a practical trial.
Reducing the stroke rate is recommended when
the saw blade engages in the material as well as
when sawing plastic and aluminium.
After longer periods of work at low stroke rate,
the machine can heat up considerably. Remove
the saw blade from the machine and allow the
machine to cool down by running it for approx.
3 minutes at maximum stroke rate.
Working Advice
fWhen working small or thin work pieces, al-
ways use a sturdy support or a saw table
(accessory).
While working, hold the machine by the handle
16 and guide it alongside the desired cutting
line. For precise cuts and quiet running, guide
the machine additionally with the other hand by
the plastic cap 1.
Contact Protector
The contact protector 13 attached to the casing
prevents accidental touching of the saw blade
during the working procedure and may not be
removed.
Plunge Cutting (see figures I – J)
fPlunge cuts may only be applied to soft ma-
terials, such as wood, gypsum plaster
boards, etc.!
Use only short saw blades for plunge cutting.
Plunge cutting is possible only with the mitre an-
gle set at 0°.
1–2: Low stroke rate
3–4: Medium stroke rate
5–6: High stroke rate
OBJ_BUCH-655-004.book Page 12 Wednesday, July 1, 2009 5:13 PM

English | 13
Bosch Power Tools 1 609 929 S83 | (1.7.09)
Place the machine with the front edge of the
base plate 7on to the workpiece without the
saw blade 12 touching the workpiece and
switch on. For machines with stroke rate con-
trol, select the maximum stroke rate. Firmly
hold the machine against the workpiece and by
tilting the machine, slowly plunge the saw blade
into the workpiece.
When the base plate 7fully lays on the work-
piece, continue sawing along the desired cutting
line.
Parallel Guide with Circle Cutter (Accessory)
For cuts using the parallel guide with circle cut-
ter 25 (accessory), the thickness of the material
must not exceed a maximum of 30 mm.
Parallel Cuts (see figure K): Loosen the locking
screw 24 and slide the scale of the parallel guide
through the lead 23 in the base plate. Set the
desired cutting width as the scale value on the
inside edge of the base plate. Tighten the lock-
ing screw 24.
Circular Cuts (see figure L): Set the locking
screw 24 to the other side of the parallel guide.
Slide the scale of the parallel guide through the
lead 23 in the base plate. Drill a hole in the work-
piece centred in the section to be sawn. Insert
the centring tip 26 through the inside opening of
the parallel guide and into the drilled hole. Set
the radius as the scale value on the inside edge
of the base plate. Tighten the locking screw 24.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be
applied alongside cutting line because of the
material heating up.
Maintenance and Service
Maintenance and Cleaning
fBefore any work on the machine itself, pull
the mains plug.
fFor safe and proper working, always keep
the machine and ventilation slots clean.
Clean the saw blade holder regularly. For this,
remove the saw blade from the machine and
lightly tap out the machine on a level surface.
Heavy contamination of the machine can lead to
malfunctions. Therefore, do not saw materials
that produce a lot of dust from below or over-
head.
fIn extreme working conditions, conductive
dust can accumulate in the interior of the

针对线锯的安全规章
f工作时如果安装在电动工具上的工具可能割断隐藏
的电线或电动工具本身的电源线，一定要握住绝缘
手柄操作电动工具。安装在电动工具上的工具如果
接触了带电的线路，电动工具上的金属部件会导电，
可能造成操作者触电。
f双手必须远离锯割范围，手不可以握在工件下端。
如果不小心碰触了锯片可能被割伤。
f先开动电动工具后再把工具放置在工件上切割。如
果电动工具被夹在工件中，会有反击的危险。
f锯割时必须把底盘 7 正确地放置在工件上。锯片如
果歪斜了，可能断裂或者造成反击。
f工作告一段落时，必须先关闭电动工具并等待机器
完全静止后，才可以从锯缝中拔出锯刀。如此不但
可以防止反击，而且可以防止放置机器时发生危险。
f只能使用锋利而且完好的锯刀。变形或变钝的锯刀
容易断裂，或者导致反击。
f关机后不可以侧压刀片来制止仍然继续转动的刀片。
锯刀可能因此受损、断裂或者造成反击。
f使用合适的侦测装置侦察隐藏的电线，或者向当地
的相关单位寻求支援。接触电线可能引起火灾並让
操作者触电。损坏了瓦斯管会引起爆炸。凿穿水管
不仅会造成严重的财物损失，也可能导致触电。
f固定好工件。使用固定装置或老虎钳固定工件，会
比用手持握工件更牢固。
f工作场所必须保持清洁。不同的工作尘经过混合后
容易产生化学反应，十分危险。轻金属尘容易著火
或引起爆炸。
f等待电动工具完全静止后才能够放下机器。机器上
的工具可能在工作中被夹住，而令您无法控制电动
工具。
f勿使用电线已经损坏的电动工具。如果电源电线在
工作中受损，千万不可触摸损坏的电线，並马上拔
出插头。损坏的电线会提高使用者触电的危险。
