Air Cleaner
Clean air filter precleaner (foam element) after every 25
operating hours and the air cleaner filter (paper ele-
ment) after every 100 operating hours. More frequent
cleaning is required when the mower is operated in
dusty or dirty conditions.

OFF. Remove high tension lead from the spark plug.
2. Remove wing nuts that secure the air cleaner cover
and remove cover. Clean cover thoroughly (Fig. 6).
3. If the foam element is dirty, remove it from the paper
element (Fig. 7). Clean foam element thoroughly.
A. WASH foam element in a solution of liquid soap
and warm water. Squeeze it to remove dirt. Do not
twist element because foam may tear.

Squeeze rag and foam element to dry element.
C. SATURATE element with clean engine oil.
Squeeze element to remove excess oil and to distrib-
ute oil uniformly. An oil damp element is desirable.

the paper element. Clean or replace paper element as
required.
A. To clean paper element, tap filter gently to re-
move dirt and debris. Do not use compressed air to
clean paper element.

cleaner cover. Tighten wing nuts.

cleaner element because extreme engine wear and
damage will likely result.
