To switch on the sawdust blower device: When
working with high material removal in wood,
plastic and other similar materials, push the
switch (14) towards the extraction outlet.
To switch off the sawdust blower device: When
working in metal and with a dust extraction sys-
tem connected, push the switch (14) towards
the saw blade.
Starting Operation
Switching On and Off (3 601 EB3 0..)
To switch on the power tool, press the lock-off button (5)
next to the symbol first, thereby deactivating it. Then
press the on/off switch (6) and keep it pressed.
The worklight lights up when the on/off switch (6) is lightly
or fully pressed allowing the work area to be illuminated in
poor lighting conditions.
Do not look directly into the worklight; it can blind
u
you.
To switch off the power tool, release the on/off switch (6).
Activate the lock-off button (5) by pressing the lock-off but-
ton next to the symbol .
Switching On and Off (3 601 EB2 0..)
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To switch on the power tool, slide the on/off switch (6) for-
wards so that "I" appears at the switch.
To switch off the power tool, slide the on/off switch (6)
backwards so that "0" appears at the switch.
Switching On the Worklight (3 601 EB2 0..)
To switch the worklight (4) on or off, press the worklight
button (18).
Do not look directly into the worklight; it can blind
u
you.
Controlling/preselecting the stroke rate (3 601 EB3 0..)
You can variably adjust the stroke rate of the power tool
when it is on by pressing in the on/off switch (6) to varying
extents.
Applying light pressure to the on/off switch (6) results in a
low stroke rate. Applying increasing pressure to the switch
increases the stroke rate.
You can preselect the stroke rate and change it during opera-
tion using the stroke rate preselection thumbwheel (7).
The required stroke rate is dependent on the material and
the work conditions and can be determined using practical
tests.
It is recommended that you reduce the stroke rate when
placing the saw blade on the workpiece and when sawing
plastic and aluminium.
During prolonged periods of use at a low stroke rate, the
power tool may heat up significantly. Remove the saw blade
and let the power tool run at the maximum stroke rate for
around three minutes to cool down.

Preselect the stroke rate (3 601 EB2 0..)
You can preselect the stroke rate and change it during opera-
tion using the stroke rate preselection thumbwheel (7).
The required stroke rate is dependent on the material and
the work conditions and can be determined using practical
tests.
It is recommended that you reduce the stroke rate when
placing the saw blade on the workpiece and when sawing
plastic and aluminium.
During prolonged periods of use at a low stroke rate, the
power tool may heat up significantly. Remove the saw blade
and let the power tool run at the maximum stroke rate for
around three minutes to cool down.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted battery temperature range, the speed is reduced
or the power tool switches off. At reduced speed, the power
tool will run again at full speed once the permitted battery
temperature is reached or the load is reduced. If it automat-
ically shuts down, switch the power tool off, allow the bat-
tery to cool down, then switch the power tool back on.
Working Advice
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Switch the power tool off immediately if the saw blade
u
becomes blocked.
Always use a sturdy support when working on small or
u
thin workpieces.
Before sawing into wood, chipboard, building materials,
etc., check for and remove any foreign objects such as nails,
screws, etc.
Jigsaws are primarily designed for curved cuts. The range of
products from Bosch also includes accessories which enable
straight cuts or circular cuts (depending on the jigsaw
model, e.g. parallel guide, guide rail or circle cutter).
Hand-held jigsaws generally tend to go off at an angle, i.e.
under certain circumstances the angle and cutting accuracy
can no longer be ensured. Decisive influencing factors on the
accuracy are the saw blade thickness, cutting length and the
material thickness and strength of the workpiece.
Therefore, always check using test cuts whether the cutting
result of the selected system meets the requirements of your
application.
Plunge cutting (see figure I)
Plunge cuts may only be applied to soft materials,
u
such as wood, gypsum board, etc.
For plunge cutting, use only short saw blades. Plunge cutting
is possible only with a mitre angle of 0°.
Place the power tool so that the front edge of the base plate
(12) rests on the workpiece, without the saw blade (17)
touching the workpiece, and switch it on. On power tools
