EXHAUST - SPARK ARRESTOR

WARNING
Do not clean spark arrestor immediately after the
engine has been run, as the exhaust system becomes
very hot. Serious burns could result from contact with
the exhaust components. Allow components to cool
sufficiently before proceeding.
Wear eye protection and gloves.
Never run the engine in an enclosed area. Exhaust
contains poisonous carbon monoxide gas that can
cause loss of consciousness or death in a very short
time.
Periodically clean spark arrestor to remove accumulated
carbon.
1. Allow engine and exhaust system to completely cool.
2. Remove the retaining screw, washer and spark
arrestor from the end of the silencer.
3. Use a non-synthetic brush to clean the arrestor
screen.
4. Inspect the screen for wear and damage. Replace if
needed.
5. Reinstall the arrestor and torque the screw to
specification.
