Replacing Air Filter

MAINTENANCE

Replacing Air Filter

If the engine seems weak or runs unevenly, the air filter may be clogged. If run with a dirty air filter, the spark plugs can become fouled, disturbing operation.

For this reason, it is important to replace the air filter regularly (see the heading Maintenance Schedule for the proper service interval).

To clean/replace the air filter:

WARNING!

Allow the exhaust system to cool before performing service. Risk for burns.

IMPORTANT INFORMATION

Operating the engine without an air filter, or with a damaged air filter, will allow dirt to enter the engine, causing rapid engine wear. This type of damage is not covered by the Distributor’s Limited Warranty.

Inspection

Push up latches on the sides of the air cleaner case. Remove the air cleaner cover and inspect the filter elements. Clean or replace dirty filter elements. Always replace damaged filter elements.

1.Remove the paper and foam elements.

2.Inspect both air filter elements and replace them if they are damaged. Always replace the paper filter element at the scheduled interval (200 hours).

3.To clean the foam element wash in detergent and warm water, and let the element air-dry thoroughly before installing it.

4.To clean the paper element, tap it gently on a flat surface to remove dust.

5.Clean the housing with detergent and water and dry thoroughly.
