3.6 Spark Arrestor Maintenance
If the generator has been running, the mufer will be very hot. Allow it to cool before proceeding.
CAUTION!
• The spark arrestor must be serviced every 100 hours to maintain its efciency, or a decrease in horsepower
may occur.
• Because of the size of the spark arrester opening in the exhaust grill you may decide that you do not want to
take off the grill. This will not cause an issue unless you drop the arrester or the clamp or screws behind the
grill. Taking the grill off or leaving it on is a matter of your convenience, but the procedure below will include
removing the grill.
NOTE:
1. Remove the six M6 screws and remove the mufer grill.
2. Remove the two M4 screws holding the spark arrester to the mufer.
3. Use a stiff wire brush to remove carbon deposits from the spark arrester screen.
4. Inspect the screen for holes, and replace it if necessary.
5. Reinstall the spark arrester.
6. Reinstall the mufer grill.
