correctly (see "Adjusting the Laser", page 36). The laser
beam, as an example, can misadjust due to vibrations after in-
tensive use.

Cutting Off
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Adjust the requested mitre and/or bevel angle.
– Switch on the machine.
– Press lever 22 and slowly guide the tool arm downward by
handle 4.
– Saw through the workpiece applying uniform feed.

Sawing Workpieces of the Same Length (see figure P)
The material stop 27 can be used for easily sawing workpiec-
es to the same length.
The material stop can be mounted on either side of the saw ta-
ble extension 15.
– Loosen lock screw 28 and swing the material stop 27 over
clamping screw 55.
– Retighten lock screw 28.
– Adjust the saw table extension 15 to the desired length
(see "Extending the Saw Table", page 32).
Special Workpieces
When sawing curved or round workpieces, these must be es-
pecially secured against slipping. At the cutting line, no gap
may exist between workpiece, fence and saw table.
Provide for special fixtures, if required.
