clamp.
While clamping the workpiece, do not reach
under the clamping lever of the quick-
clamping fixture with your fingers.

Adjusting the Cutting Angle

Before any work on the machine itself, pull
the mains plug.
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 65).
Always tighten the locking knob 27 firmly
before sawing. Otherwise the saw blade can
become wedged in the workpiece.
– Bring the power tool into the chop and mitre
saw working position. (see "Working Posi-
tion", page 59)

Adjusting Horizontal Standard Mitre Angles

(see figure F)
For quick and precise adjustment of commonly
used mitre angles, detents 29 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 27 in case it is tight-
ened.
– Pull lever 28 and rotate the saw table 24 left
or right to the requested detent.
– Release the lever again. The lever must be
felt to engage in the detent.

Adjusting Any Horizontal Mitre Angle

(see figure G)
The horizontal mitre angle can be set in the
range from 48° (left side) to 48° (right side).
– Loosen the locking knob 27 in case it is tight-
ened.
– Pull lever 28 and at the same time push the
locking bracket 47 until it engages in the
groove intended for this. The saw table can
be moved freely now.
– Turn the saw table 24 left or right by the lock-
ing knob and adjust the requested mitre an-
gle with help of the fine scale 48. (also see
