SPARK ARRESTOR MAINTENANCE

the muffler slots.
4. Using a small flat blade screwdriver, carefully pry the spark
arrestor screen out from the inside of the spark arrestor hood.

flip the spark arrestor hood closed.
8. Replace the screw you removed in Step 2 and tighten it
securely.

If the exhaust deflector assembly is not
tightened securely, it could fall off causing damage to
the unit and possible serious personal injury.
