– Push the locking lever 41 and at the same time lower the
tool arm via handle 5 until the transport safety-lock engag-
es in the end position.
The tool arm is now securely locked for transport.

Preparing for Operation

Extending the Saw Table (see figure F)
Long workpieces must be underlaid or supported at their free
end.
– Push tensioning lever 37 upward.
– Pull out saw-table extension 36 to the desired length (max.
225 mm).
– Lock in place by pushing tensioning lever 37 down again.
Extending the Fence (see figure G)
For bevel angles, the fence extensions 19 must be moved.
– Loosen the locking screw 20 and pull the fence extension
19 completely outward.
– Retighten the screw again.
Clamping the Workpiece (see figure H)
To ensure optimum working safety, the workpiece must al-
ways 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-action clamp with your fin-
gers.
– Press the workpiece firmly against the fence 18.
– Insert the quick-action clamp 21 into one of the holes 53
intended for this purpose.
– Adapt the quick-action clamp to the workpiece by turning
the threaded rod 55.
– Push on the clamping lever 54 in order to clamp the work-
piece.
Adjusting Mitre 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 34).
 Always tighten the locking knob 12 firmly before saw-
ing. Otherwise the saw blade can become wedged in the
workpiece.
Adjusting Standard Mitre Angles (see figure I)
For quick and precise adjustment of commonly used mitre an-
gles, detents 15 have been provided for on the saw table:
Left
0°
15°; 22.5°;
31.6°; 45°; 52°
– Loosen the locking knob 12 in case it is tightened.
– Pull lever 13 and rotate the saw table 16 left or right to the
requested detent.
– Release the lever again. The lever must be felt to engage in
the detent.

Adjusting Any Mitre Angle (see figure J)
The mitre angle can be set in the range from 52° (left side) to
60° (right side).
– Loosen the locking knob 12 in case it is tightened.
– Pull lever 13 and at the same time push the locking bracket
11 until it engages in the groove intended for this. The saw
table can be moved freely now.
– Turn the saw table 16 left or right by the locking knob until
the angle indicator 68 indicates the requested mitre angle.
– Tighten the locking knob 12 again.
Adjusting 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 34).
The vertical bevel angle can be adjusted in a range from 47°
(leftward) to 46° (rightward).
For quick and precise adjustment of commonly used bevel an-
gles, stops are provided for 0°, 45° and 33.9° angles.
Bevel angle range
– Pull the left fence extension 19 completely outward. (see
"Extending the Fence", page 31).
– Loosen the lock lever 14.
– Tilt the tool arm leftward via handle 5 until the angle indica-
tor 31 indicates the desired bevel angle.
– Hold the tool arm in this position and retighten the clamp-
ing lever 14.
The clamping force of the clamping lever must securely
hold the position of the tool arm at any bevel angle.
Bevel angle range
– Pull the right fence extension 19 completely outward. (see
"Extending the Fence", page 31).
– Loosen the lock lever 14.
– Lightly tilt the tool arm leftward out of the 0° position via
handle 5 and turn knob 39 until the desired bevel angle
range is indicated.
– Tilt the tool arm via handle 5 to the right until angle indica-
tor 22 indicates the desired bevel angle.
– Hold the tool arm in this position and retighten the clamp-
ing lever 14.
The clamping force of the clamping lever must securely
hold the position of the tool arm at any bevel angle.
Standard 0° Bevel Angle
To enable simple and swift resetting of the standard 0° bevel
angle, knob 39 will engage in the
Right
– Tilt the tool arm from right to left over the 0° position.
Bevel angle range
15°; 22.5°;
– Pull both fence extensions 19 completely outward. (see
31.6°; 45°; 60°
"Extending the Fence", page 31).
– Loosen the lock lever 14.
– Lightly tilt the tool arm leftward out of the 0° position via
handle 5 and turn knob 39 until the desired bevel angle
range is indicated.
– Tilt the tool arm via handle 5 to the left or right until angle
indicator 31 or 22 indicate the desired bevel angle.
