Exhaust System - Echo PB-755S H Operator's Manual

MAINTENANCE
Overheating and engine seizure can
occur when:
• Air intakes are blocked, preventing
cooling air from reaching the
cylinder.
• Dust and grass build up on the
outside of the cylinder. This build
up insulates the engine and
prevents the heat from leaving.
Removal of cooling passage
blockages or cleaning of cooling fins is considered "Normal Maintenance." Any
failure attributed to lack of maintenance is not warranted.
Cleaning Grill
1. Brush accumulated debris from intake grill between backpack frame and
blower housing.
Cleaning Cylinder Fins
1. Disconnect spark plug lead from
spark plug, and remove engine
cover.
2. Clean cylinder fins (A) to allow
cooling air to pass freely.
3. Install engine cover and attach
spark plug lead.
