Operating Modes

Before any work on the power tool 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 prac-
tical testing. The following recommendations
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
direction of the grain, work with maximum
orbital action.
Adjusting the Cutting Angle (see figure G)
The base plate 9 can be swivelled by 45° to the
left or right for bevel cuts.
Remove the dust cover 18 and the vacuum con-
nection 7.
Release the clamping lever 24 of the base plate
and lightly push the base plate 9 toward the
mains cable.
For adjustment of precise bevel 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 22.
Other bevel angles can be adjusted using a pro-
tractor.
Afterwards, push the base plate 9 to the stop in
the direction of the saw blade 15.
Bosch Power Tools
Close the base plate clamping lever 24 to lock
the base plate in the adjusted position.
The dust cover 18, vacuum connection 7 and
splinter guard 21 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 18 (see "Dust Cover",
page 10).
Release the clamping lever 24 of the base plate
and push the base plate 9 toward the mains
cable to the stop.
Close the base plate clamping lever 24 to lock
the base plate in the adjusted position.
Sawing with the base plate 9 offset is possible
only with a bevel angle of 0°. In addition, the
parallel guide with circle cutter 27 (accessory)
as well as the splinter guard 21 may not be used.
Changing the Pre-tension of the Base Plate
With the dial control 23, the pre-tension of the
base plate clamping lever 24 can be changed.
When the base plate 9 is not seated tightly after
closing the lever, open the clamping lever and
turn the dial control for pre-tension of the base
plate in the "+" direction.
When the base plate cannot be adjusted or only
with difficulty after opening the clamping lever,
turn the dial control in the " – " direction.
Precision Control
Precision Control improves the lateral stability
of the inserted saw blade. The lateral guidance
from the Precision Control guide cheeks 13
enable precise cuts.
To switch on Precision Control, push button 12.
To switch off Precision Control, press the SDS
lever 19 sideward to the stop and eject the saw
blade 15. Reinsert the saw blade afterwards, if
required.
Wear protective gloves when changing the
saw blade. The ejected saw blade can be hot.
Precision Control can be used for all applications,
even for mitre cuts. It is especially recommended
for cuts in thick wood: The lateral guidance en-
sures that the cutting angle is maintained and
reduces run-off of the saw blade (also see "Saw-
ing Thick Wood", page 12).
