clean, fresh unleaded gasoline with a minimum octane

The in-line fuel filter (Figure 7-6) should be replaced
after every 500 hours of operation or annually, whichever
occurs first.
1. Close the shutoff valve. Remove the two clamps
securing the fuel filter to the fuel hose. Remove the
fuel filter.

proper direction. Secure to the fuel hose using the
two clamps.

7.6 ENGINE AIR CLEANER
A. Cleaning and/or Replacing Air Cleaner
Element
For any air cleaner, the operating environment dictates
the air cleaner service periods. Inspect and clean the air
cleaner element after every 100 hours of operation or bi-
weekly, whichever occurs first and replace the element if
required.
-NOTE-
In extremely dusty conditions it may be
necessary to check the element once or twice
daily to prevent engine damage.
1. Remove the wing nut securing the air cleaner
cover to the engine. Remove the air cleaner
cover and set aside.
2. Remove the air cleaner and inspect.
3. Clean or replace the air cleaner and foam pre-
cleaner as recommended by the engine
manufacturer.
To avoid injury from burns, allow the mower to
cool before removing the fuel tank cap and
refueling.
