MAINTENANCE
Spark Arresting Muffler
The muffler is equipped with a spark arrester screen. A faulty
spark arrester screen can create a fire hazard. Through normal
use the screen can become dirty and should be inspected
weekly and cleaned as required.
To clean:
• Allow the muffler to cool.
• Remove the two (2) deflector screws (A).
• Remove the deflector (B) and spark arrester (C).
• Clean and inspect the spark arrester screen. If the spark
arrester screen is damaged, faulty or deteriorated, replace the
screen.
• Reassemble components in reversed order of removal and
torque deflector screws to 43 in/lbs (4.9 Nm).

Engine
Clean the cylinder & flywheel fins with compressed air or a brush
periodically. Dangerous overheating of engine may occur due to
impurities on the cylinder.
WARNING
Never run the saw without all the parts, including the
drivecase cover and starting housing, securely in place.
Because parts can fracture and pose a danger of thrown
objects, leave repairs to the flywheel and clutch to
trained John Deere Servicing Dealers.
