CLEAN SPARK ARRESTOR SCREEN
(50 STATE)
The engine exhaust muffler has a spark arrestor screen. Inspect and
clean the screen every 50 hours of operation or once each year,
whichever comes first.
Clean and inspect the spark arrestor as follows:
• Remove the screen retainer by removing the retainer clamp.
• Slide the spark arrestor screen out from the muffler outlet tube.
• Inspect screen and replace if torn, perforated or otherwise
damaged. Do NOT use a defective screen. If screen is not
damaged, clean with a commercial solvent.
• Replace the screen and retainer and secure with retainer clamp.
