Dust/Chip Extraction

Before any work on the machine itself, pull
the mains plug.
Mounting the Extraction Adapter (see figure F)
Attach the extraction adapter 27 onto the sawdust
ejector 16 until it latches. A vacuum hose with a diam-
eter of 35 mm can be connected to the extraction
adapter 27.
The extraction adapter may not be mounted
when no external dust extraction is con-
nected. Otherwise the extraction channel can
become clogged.
Do not connect a dust bag to the extraction
adapter. Otherwise the extraction system can
become clogged.
To ensure optimum extraction, the extraction adapter
27 must be cleaned regularly.
External Dust Extraction
Connect the vacuum hose 31 to a vacuum cleaner
(accessory). An overview for connecting to various
vacuum cleaners can be found at the end of this man-
ual.
The machine can be plugged directly into the recep-
tacle of a Bosch all-purpose vacuum cleaner with
remote starting control. The vacuum cleaner starts
automatically when the machine is switched on.
The vacuum cleaner must be suitable for the material
being worked.
When vacuuming dry dust that is especially detrimen-
tal to health or carcinogenic, use a special vacuum
cleaner.
Operation

Operating Modes

Before any work on the machine itself, pull
the mains plug.
Adjusting the Cutting Depth (see figure C)
Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the blade
teeth should be visible below the workpiece.
Loosen the clamping lever 24. For a smaller cutting
depth, pull the saw away from the base plate 14; for a
larger cutting depth, push the saw toward the base
plate 14. Adjust the desired cutting depth at the cut-
ting -depth scale. Tighten the clamping lever 24 again.
The tightening tension of the clamping lever 24 can be
readjusted. For this, unscrew the clamping lever 24,
and screw it back again turned offset by at least 30°
in anticlockwise direction.

Adjusting the Cutting Angle
It is best to place the machine on the face side of the
blade guard 17.
Loosen the wing bolts 7 and 15. Tilt the saw side-
wards. Adjust the desired measure on the scale 5.
Tighten the wing bolts 7 and 15 again.
Note: For bevel cuts, the cutting depth is smaller than
the setting indicated on the cutting-depth scale 25.
Cutting Marks
45 0
The 0° cutting mark (10) indicates the position of the
saw blade for right-angled cuts. The 45° cutting mark
(9) indicates the position of the saw blade for 45°
cuts.
For precise cuts, position the circular saw against the
workpiece as shown in the figure. It is best to carry out
a trial cut.

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V can
also be operated with 220 V.
Check the adjustment of the riving knife before start-
ing operation of the machine.
Switching On and Off
To start the machine, first push the lock-off button for
the On/Off switch 2 and then press the On/Off
switch 1 and keep it pressed.
To switch off the machine, 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.
