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 10, even during operation.
No orbital action
Small orbital action
Medium orbital action
Large orbital action
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 I)
The base plate 9 can be swivelled by 45° to the
left or right for mitre cuts.
– Remove the dust cover 11 and the vacuum
connection 7.
– Pull the saw blade storage 8 out of the base
plate 9.
– Loosen the screw 23 and lightly slide the
base plate 9 toward the vacuum connection
7.
– For adjustment of precise mitre angles, the
base plate has adjustment notches on the
left and right at 0°, 22.5° and 45°. Swivel the
base plate 9 to the desired position accord-
ing to the scale 22. Other mitre angles can be
adjusted using a protractor.
– Afterwards, push the base plate 9 to the stop
in the direction of the saw blade 14.
– Tighten the screw 23 again.
The dust cover 11, vacuum connection 7 and
splinter guard 20 cannot be used for mitre cuts.
Bosch Power Tools
Cut Control for Bevel Cuts (see figure J)
For cutting-line control of bevel cuts, the "Cut
Control" viewing window 15 has a mark 24 for
0° right-angle cuts and a mark 25 each for the
left- or rightward sloping 45° bevel cut accord-
ing to scale 22.
The cutting mark for bevel cuts between 0° and
45° results proportionally. It can additionally be
drawn on the "Cut Control" viewing window 15
with a non-permanent marker, and easily be re-
moved again.
For accurate working, it is best to carry out a
test cut.
Offsetting the Base Plate (see figure I)
For sawing close to edges, the base plate 9 can
be offset to the rear.
Loosen the screw 23 and slide the base plate 9
toward the vacuum connection 7 to the stop.
Tighten the screw 23 again.
Sawing with the base plate 9 offset is possible
only at a 0° bevel angle. Additionally, "Cut Con-
trol" may not be used together with the base 13,
the parallel guide with circle cutter 27 (accesso-
ry), as well as the splinter guard 20.

Starting Operation

Inserting the Battery
Use only original Bosch lithium ion batter-
ies with the voltage listed on the nameplate
of your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
Switching On and Off
To start the machine, first push the lock-off but-
ton for the On/Off switch 1 and then press the
On/Off switch 2 and keep it pressed.
The power light 18 lights up when the On/Off
switch 2 is slightly or completely pressed, and
allows the work area to be illuminated when
lighting conditions are insufficient.
To switch off the machine, release the On/Off
switch 2.
Note: For safety reasons, the On/Off switch 2
cannot be locked; it must remain pressed during
the entire operation.
