Press the splinter guard 19 from below into the
base plate 9 (with the notch facing upward as
shown in the figure).
The splinter guard 19 can be inserted into the
base plate in 2 positions. For narrow saw
blades, insert the splinter guard fully to the
front; for wider saw blades, insert it further to
the rear in the base plate 9.
When using the sliding shoe 8, the splinter
guard 19 is not inserted into the base plate 9,
but into the sliding shoe.
Sliding Shoe
When working surfaces that are easily
scratched, the sliding shoe 8 can be attached
onto the base plate 9 in order to prevent the sur-
face from being scratched.
To attach the sliding shoe 8, insert it at the front
of the base plate 9, push the rear part upward
and allow it to latch.
Operation

Operating Modes

Before any work on the machine itself, pull
the mains plug.
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 11, even during operation.
Setting 0 No orbital action
Setting I Small orbital action
Setting II Medium orbital action
Setting III 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.
Bosch Power Tools
– 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 G)
The base plate 9 can be swivelled by 45° to the
left or right for mitre cuts.
Remove the dust cover 16 and the vacuum con-
nection 7.
Release the clamping lever 22 of the base plate
and lightly push the base plate 9 toward the
mains cable.
For adjustment of precise mitre angles, the base
plate has adjustment notches on the left and
right at 0° and 45°. Swivel the base plate 9 to
the desired position according to the scale 20.
Other mitre angles can be adjusted using a pro-
tractor.
Afterwards, push the base plate 9 to the stop in
the direction of the saw blade 14.
Close the base plate clamping lever 22 to lock
the base plate in the adjusted position.
The dust cover 16, vacuum connection 7 and
splinter guard 19 cannot be used for mitre cuts.
Offsetting the Base Plate (see figure H)
For sawing close to edges, the base plate 9 can
be offset to the rear.
Remove the dust cover 16 (see "Dust Cover",
page 22).
Release the clamping lever 22 of the base plate
and push the base plate 9 toward the mains ca-
ble to the stop.
Close the base plate clamping lever 22 to lock
the base plate in the adjusted position.
Sawing with the base plate 9 offset is possible
only with a mitre angle of 0°. In addition, the
parallel guide with circle cutter 25 (accessory)
as well as the splinter guard 19 may not be used.
