Bosch Power Tools
Clamping the Workpiece (see figure I)
To ensure optimum working safety, the work-
piece must always be firmly clamped.
Do not saw workpieces that are too small to
clamp.
While clamping the workpiece, do not reach
under the clamping lever of the quick-ac-
tion clamp with your fingers.
– Press the workpiece firmly against the
fence 6.
– Insert the quick-action clamp 7 into one of
the holes 17 intended for this purpose.
– Adapt the quick-action clamp to the work-
piece by turning the threaded rod 44. – Push on the clamping lever 43 in order to
clamp the workpiece.

Adjusting the Cutting Angle

To ensure precise cuts, the basic adjustment of
the machine must be checked and adjusted as
necessary after intensive use (see "Checking
and Adjusting the Basic Adjustment", page 42).
Always tighten the locking knob 12 firmly
before sawing. Otherwise the saw blade can
become wedged in the workpiece.
Adjusting Horizontal Standard Mitre Angles
(see figure J)
For quick and precise adjustment of commonly
used mitre angles, detents 14 have been provid-
ed for on the saw table:
Left Right
0°
15°; 22,5°; 15°; 22,5°;
31,6°; 45° 31,6°; 45°
– Loosen the locking knob 12 in case it is tight-
ened.
– Pull lever 13 and rotate the saw table 15 left
or right to the requested detent.
– Release the lever again. The lever must be
felt to engage in the detent.
