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.
