of the saw table and turn the arbor with the spanner until the
locking pin engages in the hole in the saw arbor pulley.
Now unlock the nut.

7.2 Mounting the raving knife
The supplied raving knife must always be used.
The machine is equipped with a raving knife for the use of
sawblades diameter 250 to 315 mm.
The raving knife has to be adjusted in such a way that over
its entire length the gap between sawblade and raving knife
does not exceed min.3 mm and max.8 mm. (Fig 25).
The raving knife (P, Fig 26) can be adjusted in both vertical
and horizontal direction.
The height setting has to be adjusted in such a way that the
sawguard bottom never exceeds more than 3 mm above the
highest placed sawblade tooth.
After height adjustment always locks the central bolt (Q).
The raving knive is side adjusted ex works.
The 4 little adjustment screws are used for the exact setting
of the raving knife in line with the sawblade.
For slotting or grooving a special raving knife is needed.
The raving knife has to be adjusted in such a way that the
upper part of the raving knife is never set lower than the
highest sawtooth in use.
Never remove this raving knife.
Kickbacks are severe and very dangerous.
No submerged cuts by removing the raving knife and/or saw
guard may be performed.
7.3 Mounting the saw guard
Fig 25
The sawguard (O, Fig 26) must always be used.
Attach the saw guard to the raving knife (P), in the slot (S)
matching the sawblade diamenter.
The sawguard must be lowered to the workpiece to minimise
the amount of exposed teeth.
Adjustment shall never be performed when the machine is
running.
The saw guard has to be connected to the dust extractor
system.
7.4 Rising and tilting sawblade
Setup adjustments of the sawblade shall never be performed
when the machine is running.
Use the front handwheels to raise the sawblade (1, Fig 27).
One turn of the handwheel equals 7.5 mm of height setting.
