Clean Spark Arrester Screen
The engine exhaust muffler may be equipped a spark arrester
screen. If equipped, inspect and clean the screen every

covered, or grass-covered unimproved land, it must have a
spark arrester.The spark arrester must be maintained in good
condition by the owner/operator.
If the engine has been running, the muffler will be very hot.
Allow the muffler to cool before servicing the spark arrester.
• Remove spark arrester screen for cleaning and inspection
(see Figure 18) by loosening and removing the screws in the
muffler guard used to hold the screen.
• Inspect screen and replace if torn, perforated or otherwise
damaged. DO NOT use a defective screen. If screen is not
damaged, clean it with commercial solvent.
• Reattach spark arrester screen to muffler guard by installing
the screws in the holes provided.
