ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Dust Cover (see figures E–F)
Mount the dust cover 9 before connecting the machine to the
dust extraction.
Mount the dust cover 9 onto the machine in such a manner that
the centre holder engages on the contact protector 18 and the
two outer holders engage in the openings on the casing.
Remove the dust cover 9 for applications without dust extrac-
tion as well as when performing mitre cuts. For this, push the
dust cover together at the two outer holders and pull it off
toward the front.
Connecting the Dust Extraction
Place a vacuum hose 3 (accessory) onto the vacuum connec-
tion 4. Connect the vacuum hose 3 with a vacuum cleaner (ac-
cessory). An overview for the connection of various vacuum
cleaners can be found at the end of these instructions.
Switch the saw dust blower off when a dust extraction system
is connected (see "Sawdust Blower Device").
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
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 ma-
terial being sawed.
The orbital action can be adjusted with the adjusting lever 7,
even during operation.
No orbital action
Small orbital action
Medium orbital action
Large orbital action
The optimal orbital action setting for the respective applica-
tion can be determined through practical testing. The follow-
ing 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.
Bosch Power Tools
– 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 6 can be swivelled by 45° to the left or right for
mitre cuts.
The dust cover 9 and the splinter guard 16 cannot be used
when performing mitre cuts.
If required, remove the dust cover 9 (see "Dust Cover",
page 15) and take off the splinter guard 16 (see "Splinter
Guard", page 14).
Pull the saw blade storage 5 out of the base plate 6.
Loosen the screw 19 and lightly slide the base plate 6 toward
the vacuum connection 4.
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 6 to the desired position according
to the scale 20. Other mitre angles can be adjusted using a
protractor.
Afterwards, push the base plate 6 to the stop in the direction
of the saw blade 15.
Tighten the screw 19 again.
Cut Control for Bevel Cuts
21 11 10 6
For cutting-line control of bevel cuts, the "Cut Control" view-
ing window 11 has a mark 21 for 0° right-angle cuts and a
mark 22 each for the left- or rightward sloping 45° bevel cut
according to scale 20.
The cutting mark for bevel cuts between 0° and 45° results
proportionally. It can additionally be drawn on the "Cut Con-
trol" viewing window 11 with a non-permanent marker, and
easily be removed again.
For accurate working, it is best to carry out a test cut.
Offsetting the Base Plate (see figure G)
For sawing close to edges, the base plate 6 can be offset to
the rear.
Loosen the screw 19 and slide the base plate 6 toward the
vacuum connection 4 to the stop.
Tighten the screw 19 again.
Sawing with the base plate 6 offset is possible only at a 0°
bevel angle. Additionally, "Cut Control" may not be used
together with the base 10 as well as the splinter guard 16.
