The 45° cut mark
(32)
indicates the position of the saw
blade when making a 45° cut – when used without a guide
rail.
Note:
The plunge markings
(35)
indicate where the saw
blade plunges into the workpiece when used with a guide
rail.
Start-up
Inserting the battery
Push the charged battery
(21)
into the power tool until the
battery is securely locked.
Switching on/off
To
start
the power tool, first press the lock-off switch
(2)
,
then
press and hold the on/off switch
(1)
.
Pressing the lock-off switch
(2)
also unlocks the plunge func-
tion and allows the power tool to be pushed down. This
causes the application tool to plunge into the workpiece.
Raising the power tool causes it to spring back into the start-
ing position and the plunge function locks again.
To
switch off
the power tool, release the on/off switch
(1)
.
Note:
For safety reasons, the on/off switch
(1)
cannot be
locked; it must remain pressed during the entire operation.
Constant electronic control
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
ECO mode
If the power tool is operated in the energy-saving ECO mode,
the battery life may be up to 20% longer.
If the ECO mode is active, the symbol
E
is shown on the
speed setting/mode indicator
(40)
. In addition, the ECO
mode indicator
(38)
lights up.
User Interface (see figure D)
The user interface
(20)
is used to preselect the speed and to
indicate the status of the power tool.
Speed preselection
Six speed settings and the ECO mode are preset in the basic settings. Using a special application (Bosch Toolbox app), one to
six speed settings can be programmed.
The information in the table below describes the preset speeds (default settings) for each programmed number of levels.

The required speed depends on the saw blade used and the material being worked on (see the saw blade overview at the end
of these operating instructions). This will prevent the saw teeth overheating when sawing.
You can use the button for speed preselection
(39)
to preselect the required speed, even during operation.
The figures in the table below are recommended values for the basic settings with 6 preset speed settings and the ECO mode.
