Switching On and Off (GST 160 CE)
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 (3) for-
wards so that "I" appears at the switch.
To switch off the power tool, slide the on/off switch (3)
backwards so that "0" appears at the switch.
Switching On and Off (GST 160 BCE)
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To switch on the power tool, press the on/off switch (3).
To lock the on/off switch (3), keep it pressed down and
push the locking mechanism (2) to the right or left.
To switch off the power tool, release the on/off switch (3).
If the on/off switch (3) is locked, press the switch first and
then release it.
Restart protection
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.
To restart the tool, set the on/off switch (3) to the off posi-
tion and then switch the power tool on again.
Constant Electronic control
The Constant Electronic control keeps the stroke rate at no
load and under load virtually consistent, guaranteeing uni-
form performance.
Controlling the stroke rate (GST 160 BCE)
You can variably adjust the stroke rate of the power tool
when it is on by pressing in the on/off switch (3) to varying
extents.
Applying light pressure to the on/off switch (3) results in a
low stroke rate. Applying increasing pressure to the switch
increases the stroke rate.
Preselect the stroke rate
You can preselect the stroke rate and change it during opera-
tion using the stroke rate preselection thumbwheel (4).
The required stroke rate depends on the material and the
working conditions and can be ascertained through practical
tests.
A reduction in the stroke rate is recommended:
– When positioning the saw blade on the workpiece in order
to be able to position the saw blade more precisely,
– When sawing plastic and aluminium to prevent the mater-
ial from melting.
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.
Working Advice
Pull the plug out of the socket before carrying out any
u
work on the power tool.
1 609 92A 9YN | (05.02.2025)
Switch the power tool off immediately if the saw blade
u
becomes blocked.
When machining small or thin workpieces, always use
u
a stable base or saw table (accessory).
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 J)
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
(6) rests on the workpiece, without the saw blade (11)
touching the workpiece, and switch it on. On power tools
with stroke rate control, select the maximum stroke rate.
Press the power tool firmly against the workpiece and allow
the saw blade to plunge slowly into the workpiece.
As soon as the base plate (6) rests fully on the workpiece,
continue sawing along the required cutting line.
Coolant/lubricant
As the material heats up along the cutting line when cutting
metal, you should apply coolant or lubricant.
Maintenance and Service
Maintenance and Cleaning
Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
Clean the saw blade receptacle regularly. For this, remove
the saw blade from the power tool and lightly tap out the
power tool on a level surface.
If the power tool becomes very dirty, this can lead to serious
faults. For this reason, do not cut materials which generate
large quantities of dust from below or overhead.
In extreme conditions, always use a dust extractor if
u
possible. Blow out ventilation slots frequently and in-
