E) CHECKING AND REPLACING THE BLADE
Always check the state of the blade before commencing work. Do not forget to switch the
engine off!
- During work operations if the blade (Fig. 10, ref. A ) strikes stones or stumps stop
straightaway and make sure that it has not become bent or broken. A damaged blade
must be replaced.
- If the blade is very worn, cracked or bent, it makes snap and projects objects outwards,
risking serious accident.
- Use heavy-duty work gloves to check or replace the blade to avoid risk of injury to
hands.
- The blade fixing screws and relative nuts are also subject to wear. Always replace
them at the same time as the blade, using bolts and screws of the same strength and
type.
- The blade wears more quickly on dry, sandy ground. In these conditions it should be
replaced more frequently.
To remove the blade proceed as follows:
1. Switch off the engine and disconnect the spark plug wire
2. Adjust the cutting height to maximum
3. Check the state of the blade.
Check that the blade is not cracked, bent, excessively worn or broken.
