Spark arrester maintenance
•
If the generator has been running, the muffler will be very hot. Allow it to cool before proceeding.
•
The spark arrester must be serviced every 100 hours to maintain its efficiency, 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.
1.
Remove the exhaust grill to access the spark arrestor.
2.
Remove the screws holding the clamp and the spark arrester to the muffler.
3.
Clean the spark arrestor with a stiff wire brush.
4.
Replace if the wire mesh is perforated or torn.
5.
Reinstall the spark arrester and the clamp.
6.
Reinstall the exhaust grill.
