Maintaining the Spark Arrester
Inspect the spark arrester every 50 hours for damage, such 
as holes in the screen, and for build-up on the screen. If it 
is damaged, replace it with a new spark arrester. If it is 
dirty, remove it and clean the screen with a wire brush 
and/or soak it in solvent. Install it as indicated in the 
previous procedure.
