Only operate the device with an extraction system. Check
and clean the suction channels at regular intervals.
Make sure that a suitable saw blade for the material to
be cut is selected.
Connect a dust collecting device to the electric tool
when sawing wood.
Do not use saw blades made of high-speed alloy steel
(HSS steel).
Use a push stick or the handle with wooden push block
in order to guide the workpiece safely past the saw
blade. Always keep the push stick or wooden push
block on the electric tool when not in use.
Inclined adjustment of the saw blade
• After loosening the two clamping screws, the saw
blade is continuously adjustable from 90° to 45°
(see scale).
• Check the setting with a test cut.
• Re-adjust the set adjusting if necessary.
Height adjustment of the saw blade
The saw blade is continuously adjustable from 0 to 83
mm cutting height.
For safe and tidy work, select a small saw blade pro-
jection to the workpiece.
Adjust the riving knife as shown in Fig. 22.
The riving knife is an important safety device, which
guides the workpiece and prevents the kerf closing be-
hind the saw blade and the workpiece rebounding. Pay
attention to the thickness of the splitting wedge.
The riving knife must not be thinner than the body of the
saw blade and not thicker than its kerf width.
Only saw blades with a diameter of 315 mm and a thick-
ness of 2.4 mm (teeth 3.0 mm / 3.2 mm) may be used.
Lower the cover hood onto the workpiece during every
working operation. The cover hood must be horizontal
above the saw blade with each working operation.
Longitudinal cuts
For parallel cuts, use the rip fence. Use the stop ruler with
the high stop side (1) for cutting work over 120 mm and
with the low stop side (2) for cutting widths under 120 mm.
Guide the workpiece with the enclosed push stick.
Cross cuts
Use the sliding carriage for cross cuts and angled cuts.

Working on circular sawing machines
Cutting wider workpieces, Fig. 24
Width of the workpiece to be machined more than 120 mm
Work process: Set the longitudinal stop to suit the in-
tended workpiece width. Ensure that you have a safe
hand rest. If narrow workpieces are cut off by the cut,
the feed is carried out in the tool area only with the right
hand or with the aid of a push stick. If there is a risk of
the workpiece jamming between the circular saw blade,
riving knife and stop, the stop must be retracted to the
centre of the saw blade or a short auxiliary fence must
be used. In the pictures, the upper suction hood was on-
ly indicated, or in individual cases omitted, in order to
show the work process or device more clearly.
The upper suction hood is required for all operations
shown.
Cutting narrower workpieces, Fig. 25
Longitudinal cuts of workpieces with a width of less
than 120 mm must always be made with the aid of a
push stick.
Push stick is included in the scope of delivery. Replace
a worn or damaged push stick immediately.
• Set the parallel stop to suit the intended workpiece
width.
• Push the workpiece forward with both hands, and be
sure to use a push stick as a pushing aid in the area
of the saw blade.
• Always push the workpiece through to the end of the
riving knife.
Attention! For short workpieces, use the push stick as
soon as you start cutting.
Cutting edges and strips, Fig. 26
Work process: Mount the longitudinal stop with a low
contact surface or use an auxiliary fence. Push the
workpiece forward with the push stick until the end of
the workpiece is in the area of the riving knife. Secure
long workpieces against tipping at the end of the cut-
ting process with a table extension.
Carrying out cross cuts, Fig. 27
Work process: Adjust the deflector strip such that piec-
es cut off the workpiece cannot come into contact with
the rising part of the saw blade. Feed workpieces only
by means of transverse stop or transverse slide.
Do not remove waste pieces from the area of the work-
piece with your hands.
