• Determine the distance "b" from the lower edge of the grinding stone to the lower edge of
the grinding slide.
• Allow the detent pin (1) to lock into place by turning it 90° degrees.
• Measure the distance "z" (upper edge of grinding stone to upper edge of hexagon nut on
the ratchet wheel) through the nut.
• Turn back the ratchet wheel (2) until the detent pin (1) engages.
• Turn the ratchet wheel (2) further back until the detent pin (1) has completely engaged and
the grinding stone adjustment is locked in place.
• Continue turning the ratchet wheel to loosen the grinding stone clamp.
• Press the grinding stone from above to the previously determined dimension "b" -2 mm.
• Tension the grinding stone with the ratchet wheel (tightening torque 180 Nm).
• Check the dimension "b" (- 2 mm).
• Check whether the dimension "z" is less than 100 mm. If not, replace the grinding stone is it
will not hold in the clamp.
• Mount the pawl.
• Reset the grinding cycle counter in the info centre.
NOTE
The grinding stone should always be higher than the chopping blade – risk of collision!
