Engine Air Filter Maintenance
Check the
Engine Air Filter Service Indicator
before each use of the machine. Do not service the air filter unless
the red flag is visible in the service indicator.
Caution! When servicing the engine air filter elements, use extreme care to prevent loose dust
from entering the engine. Dust can severely damage the engine.
The engine air filter contains a primary (outer) and a safety (inner) filter element. The primary element can
be cleaned twice before being replaced.
The safety element should be replaced every third time that the primary filter element is replaced. Never
attempt to clean the inner safety element.
To clean the primary filter element:
1. Un-snap the two clips at the end of the air filter and remove the end housing.
2. Pull the primary element out.
3. Clean the element with compressed air (maximum pressure 100 psi) or wash it with water (maximum
pressure 40 psi). Do not put the element back into the canister until it is completely dry.
