MAINTENANCE

Cooling System

Level 2.
Parts Required: None if you are careful.
To maintain proper engine operating temperatures, cooling air must
pass freely through the cylinder fin area. This flow of air carries
combustion heat away from the engine.
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.
Note: 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 and Cylinder Fins
1. Remove accumulated debris
from intake grill between
backpack frame and blower
housing.
2. Disconnect spark plug lead
from spark plug.
3. Remove spark plug.
4. Remove engine cover.
5. Loosely install spark plug to
keep dirt out of cylinder.
6. Clean cylinder fins to allow
cooling air to pass freely.
7. Reassemble parts in reverse
order.
