To remove the flails proceed as follows:
1. Switch off the engine and disconnect the spark plug wire
2. Adjust the cutting height to maximum
3. Open the front housing.
4. Check the state of the flails.
5. Check that the flails are not cracked, bent, excessively worn or broken. If they are,
either reverse them (turning them 180°) or replace them.
F) SHARPENING THE FLAILS
To sharpen the flails proceed as follows:
1. Wear a safety helmet, goggles and heavy-duty work gloves. Work with care.
2. Hold the flail firmly.
3. Do not grind parallel to the cutting edge. Do not grind the cutting edge to razor
sharpness; leave a flat edge of 0.4-0.6 mm. If honed to razor sharpness the cutting
flail will wear down very quickly.
4. Grind all the flails in the same way so as to maintain rotor balance.
5. When grinding the flail only remove a little material at a time and spray with water to
lower the temperature. If the flail overheats during sharpening it will lose temper and
become less wear resistant.
6. If the rotor is off balance after the flails have been sharpened the resulting vibrations
may damage the machine.
