Adjusting Bevel Angles
Adjusting Standard Bevel Angles (see figure L)
For quick and precise adjustment of commonly used bevel an-
gles, stops are provided for 0°, 45° and 33.9° angles.
– Loosen clamping lever 23.
– Adjust stops 19 or 26 as follows:
Mitre/Bevel Angle Stop
0° 26
45° 19
33.9° 19
– Swing the tool arm with the handle 4 to the requested po-
sition.
– Tighten clamping lever 23 again.
Adjusting Any Bevel Angle
The bevel angle can be set in a range from –2° to +47°.
– Loosen clamping lever 23.
– Turn stop 19 completely to the front and pull stop 26 com-
pletely to the front.
The complete tilting range is now available.
– Tilt the tool arm by the handle 4 until the angle indicator 25
indicates the desired bevel angle.
– Hold the tool arm in this position and tighten clamping le-
ver 23 again.
Starting Operation
Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the machine.
Switching On (see figure M)
– For starting operation, pull the On/Off switch 33 in the di-
rection of the handle 4.
Note: For safety reasons, the On/Off switch 33 cannot be
locked; it must remain pressed during the entire operation.
The tool arm can only be guided downward when pressing le-
ver 22.
– For sawing, you must additionally press lever 22 in addi-
tion to actuating the On/Off switch 33.
Switching Off
– To switch off the machine, release the On/Off switch 33.

Bosch Power Tools
When not using the power tool, switch it off in order to save
energy.
Reduced starting current
The electronic reduced starting current limits the power con-
sumption when switching the tool on and enables operation
from a 13 ampere fuse.
Note: When the machine runs at full speed immediately after

General Sawing Instructions
centre
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
Do not saw warped/bent workpieces. The workpiece must al-
ways have a straight edge to face against the fence.
Long workpieces must be underlaid or supported at their free
end.
Marking the Cutting Line (see figure N)
A laser beam indicates the cutting line of the saw blade. This
allows for exact positioning of the workpiece for sawing, with-
out having to open the retracting blade guard.
– For this, switch the laser beam on with the switch 31.
– Align the cutting mark on your workpiece with reference to
Note: Before sawing, check if the cutting line is still indicated
correctly (see "Adjusting the Laser", page 35). The laser
beam, as an example, can misadjust due to vibrations after in-
tensive use.
Position of the Operator (see figure O)
– Keep hands, fingers and arms away from the rotating saw
– Do not cross your arms when operating the tool arm.
