24.3 Re-adjusting or replacing the grinding stone
Risk of injury due to rotating cutting drum!
If the flap of the grinding device is opened while the cutting drum is rotating, there is a risk of
injury from the sharp, rotating cutting blades.
• Do not open the flap of the grinding device until the cutting drum has come to a standstill.
Risk of fire due to deposits in the grinding channel!
A mixture of dust, grass and chaff in the grinding channel is a source of fire and means an
increased fire risk during the grinding process.
• Before grinding the cutting blades, check the automatic re-adjustment of the grinding stone
and clean the grinding channel.
The grinding stone of the grinding device is automatically re-adjusted during the grinding
process.
If automatic re-adjustment no longer occurs, the grinding stone must be re-adjusted.
The grinding stone can be re-adjusted 3 – 4 times, then the grinding stone must be replaced.
NOTE
Check the grinding stone for damage and wear and replace if required. These may cause the
grinding stone to run noisily, resulting in an uneven grinding pattern.
