Fig. 20
Loosen the 4 Phillips screws from the table inlay (19)
and remove it.
Fig. 21
Set the saw blade all the way up and loosen the screw
with the saw blade key.
Attention! Left-handed thread
Fig. 22
Remove the saw blade flange (31) and then the saw
blade (32).
Now change the saw blade.
When mounting the saw blade flange, pay attention
to the recess.
After changing the saw blade, check the riving knife
setting and refit the table inlay (19) and suction hood
(20).

8. Transport

The machine may only be transported with a suitable
lifting device (crane or forklift). The attachment point
for the rope (crane) is located on the upper belt wheel
housing.
Do not lift the machine by the saw table.
By lifting at the front of the machine, it can be easily
relocated in the workshop area to suit the space
requirements.

9. Working instructions

After every new setting, we recommend performing
a test cut, in order to check the dimensional settings.
After switching on the saw, wait until the saw blade
has reached its max. speed before making the cut.
Secure long workpieces against tipping at the end of
the cutting process (e.g. with roller stand, etc.)
Be careful when cutting in.
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 rod 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).
28 | GB
• 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
projection 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
behind 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
thickness 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 longitudinal stop. 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
intended 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 only 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.
