Adjusting Vertical Bevel Angles
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 49).
The vertical bevel angle can be adjusted in a
range from 47° (leftward) to 47° (rightward).
For quick and precise adjustment of commonly
used bevel angles, stops are provided for 0°,
45° and 33.9° angles.

– Tilt the tool arm leftward via handle 7 until
the angle indicator 33 indicates the desired
bevel angle.
– Hold the tool arm in this position and retight-

The clamping force of the clamping lever
must securely hold the position of the tool
arm at any bevel angle.
