3.10 Spark Arrestor
If the generator has been running, the muffler will be very hot. Allow the muffler to
■
cool before proceeding.
The spark arrester must be serviced every 100 hours to maintain efficiency. A
■
clogged spark arrestor will partially plug the exhaust system causing a substantial
loss in power and performance.
1. Remove the exhaust grill to access the spark arrestor (Fig. 13).
2. Remove the clamp holding the spark arrester to the muffler.
3. Remove the spark arrester.
4. Clean the spark arrestor with a wire or nylon brush and compressed air.
5. Replace the spark arrestor if the wire mesh is perforated or torn.
6. Reinstall the spark arrester.
7. Reinstall the clamp holding the spark arrester to the muffler.
8. Reinstall the exhaust grill.
