| fler to become overheated and that in turn could | B |
| cause the engine to catch on fire. Always make |
|
| sure that the muffler is clean and free of wood |
|
| chips, leaves, and other waste before use. |
|
• | Check the intake air cooling vent and the area |
|
| around the cylinder cooling fins after every 25 |

| hours of use for blockage, and remove any waste |
|
| which has attached itself to the brushcutter. Note |
|
| that it is necessary to remove the upper cover and |
|
| the lower cover shown in in order to be able to |
|
| view the upper part of the cylinder. |

IMPORTANT
•If waste gets stuck and causes blockage around the intake air cooling vent or between the cylinder fins, it may cause the engine to overheat, and that in turn may cause mechanical failure on the part of the brushcutter.
