Operation
Operating Modes
Before any work on the machine itself, pull
the mains plug.
Adjusting the Cutting Depth (see figure B)
Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the
blade teeth should be visible below the work-
piece.
Loosen the clamping lever 22. For a smaller cut-
ting depth, pull the saw away from the base
plate 12; for a larger cutting depth, push the
saw toward the base plate 12. Adjust the de-
sired cutting depth at the cutting-depth scale.
Tighten the clamping lever 22 again.
Adjusting the Cutting Angle
It is best to place the machine on the face side
of the blade guard 14.
Loosen wing bolt 7. Tilt the saw sidewards. Ad-
just the desired setting at the scale 5. Tighten
wing bolt 7 again.
Cutting Marks
45
0
The 0° cutting mark (9) indicates the position of
the saw blade for right-angled cuts. The 45° cut-
ting mark (8) indicates the position of the saw
blade for 45° cuts.
For precise cuts, position the circular saw
against the workpiece as shown in the figure. It
is best to carry out a trial cut.

Starting Operation
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To start the machine, first push the lock-off but-
ton for the On/Off switch 2 and then press the
On/Off switch 1 and keep it pressed.
To switch off the machine, release the On/Off
switch 1.
Note: For safety reasons, the On/Off switch 1
cannot be locked; it must remain pressed during
the entire operation.
Working Advice
Protect saw blades against impact and shock.
Guide the machine evenly and with light feed in
the cutting direction. Excessive feed significant-
ly reduces the service life of the saw blade and
can cause damage to the power tool.
Sawing performance and cutting quality depend
essentially on the condition and the tooth form
of the saw blade. Therefore, use only sharp saw
blades that are suited for the material to be
worked.

Sawing Wood
The correct selection of the saw blade depends
on the type and quality of the wood and whether
lengthway or crossway cuts are required.
When cutting spruce lengthways, long spiral
chips are formed.
Beech and oak dusts are especially detrimental
to health. Therefore, work only with dust extrac-
tion.
Sawing Non-ferrous Metals
Note: Use only a sharp saw blade that is suitable
for non-ferrous metals. This ensures a clean cut
and prevents blade binding.
Guide the switched on power tool against the
workpiece and carefully start the cut. Continue
the cut with low feed and without interruption.
