Exhaust System - Echo PB-580H Operator's Manual

PB-580H/T
Overheating and engine seizure can
occur when:
• Air intakes are blocked,
preventing cooling air from

• Dust and grass build up on the
outside of the cylinder. This build
up insulates the engine and
prevents the heat from leaving.

blockages or cleaning of cooling fins
is considered "Normal
Maintenance." Any failure attributed to lack of maintenance is not warranted.
