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.
E) 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 ra-
zor 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.
