Pendulum action settings
The pendulum action can be adjusted using four different
settings, allowing the cutting speed, cutting capacity and the
cut itself to be optimally adapted to the material that you
want to cut.
You can also adjust the pendulum action during operation
using the adjusting lever
(22)
.
Level 0
No pendulum action
Level I
Low pendulum action
Level II
Moderate pendulum action
Level III (MAX)
High pendulum action
The optimum pendulum level for each application can be de-
termined by a practical test. Note the following recommend-
ations:
– Select a lower pendulum level or switch off the pendulum
action completely if you wish to produce a finer or cleaner
cutting edge.
– Switch off the pendulum action when machining thin ma-
terials (e.g. sheets).
– Work on hard materials (e.g. steel) with low pendulum ac-
tion.
– You can work on soft materials and saw wood using max-
imum pendulum action.
Sawdust blower device
The cutting line can be kept clear of chips using the airflow
from the sawdust blower device.
To switch on the sawdust blower device: When working with
high material removal in wood, plastic and other similar ma-
terials, push the switch
(23)
to the
I
position.
To switch off the sawdust blower device: When working in
metal and with a dust extraction system connected, push the
switch
(23)
to the
0
position.
Starting Operation
Switching on and off (GST 18V‑155 SC)
u
Make sure that you are able to press the On/Off switch
without releasing the handle.
To
switch on
the power tool, push the right or left on/off
switch
(21)
all the way forward and let it go.
Note:
When switching on, the on/off switch
(21)
needs to be
pressed forwards for longer than when switching off in order
to prevent unintentional activation.
To
switch off
the power tool, push the right or left on/off
switch
(21)
all the way forward again and let it go.
Switching on/off and controlling the stroke rate
(GST 18V‑155 BC)
To
switch on
the power tool, press the lock-off button
(25)
next to the symbol
first, thereby deactivating it. Then
press the on/off switch
(21)
and keep it pressed.
You can variably adjust the stroke rate of the power tool
when it is on by pressing in the on/off switch
(21)
to varying
extents.
Applying light pressure to the on/off switch
(21)
results in a
low stroke rate. Applying increasing pressure to the switch
increases the stroke rate.
The maximum stroke rate depends on the stroke rate level
set in the user interface.
To
switch off
the power tool, release the on/off switch
(21)
.
Activate the lock-off button
(25)
by pressing the lock-off
button next to the symbol .
Impact shutdown
The integrated impact shutdown switches the power tool off
as soon as it hits the floor.
If the impact shutdown is triggered, the status indicator
(5)
will flash red. Information regarding the cause of the shut-
down can be found in the
Bosch Toolbox
app.
Switching the power tool on again:
–
GST 18V‑155 SC
: Push the right or left on/off
switch
(21)
all the way forward
twice
and let it go.
–
GST 18V‑155 BC
: Press and hold the on/off switch
(21)
.
You can deactivate the impact shutdown using the
Bosch
Toolbox
app.
User interface
The user interface is used as follows:
– As the power tool status indicator
– For switching the worklight on and off
– For preselecting/controlling the stroke rate
– For controlling ASC at stroke rate level 6
(
GST 18V‑155 SC
, with factory setting)
– For signalling warnings in the app (temperature depend-
ent overload protection, impact shutdown)
Status indicators
Colour of the
status
indicator (5)
Meaning
Corrective measure
–
Power tool switched off
–
Green
Power tool switched on and ready to use
–
Yellow
Critical temperature reached
Remove the saw blade and let the power tool run
at the maximum stroke rate for around 3 minutes
to cool down.
Battery almost empty
Charge the battery.
