SERVICE<br />
Service on the polyurethane element (cleaning and oiling) is recommended every three months or every twenty five<br />
operating hours, whichever comes first. Extremely dirty or dusty conditions may require daily cleanings.<br />
The paper filter element should be replaced at least once a year or more frequently if operated in dusty or dirty conditions.<br />
NOTE: NEVER RUN THE ENGINE WITHOUT THE COMPLETE AIR CLEANER ASSEMBLY INSTALLED ON THE<br />
ENGINE. ALWAYS REPLACE THE FILTER ELEMENT WITH THE PROPER TECUMSEH ORIGINAL REPLACEMENT<br />
PART.<br />
DISASSEMBLY PROCEDURE<br />
1. Unlock the tabs or remove the screws, wingnuts or<br />
snaps holding the air cleaner cover in place.<br />
2. Remove the hex nuts holding the element down if<br />
equipped. New nuts are supplied with a new filter and<br />
MUST be used for proper sealing.<br />
3. Clean the excess contaminants out of the air cleaner<br />
body before removing the old element.<br />
4. Remove the old element and the polyurethane precleaner<br />
if equipped.<br />
5. On air cleaners that use a flocked screen under the<br />
polyurethane element, remove the air cleaner assembly<br />
from the carburetor before removing the flocked screen.<br />
This prevents dirt from entering the carburetor (diag 3).<br />
6. Clean the inside of the cover and body, remove the old<br />
gasket between the carburetor and the air cleaner<br />
assembly.<br />
7. Reinstall the air cleaner assembly using a new gasket.<br />
8. Use the reverse procedure for reassembly. When<br />
installing the foam polyurethane pre-cleaner, make sure<br />
the seam is installed to the outside to prevent gaps<br />
between the paper element and the pre-cleaner.<br />

This type of air filter can be serviced when restricted with dust or dirt. Wash the filter or pre-cleaner in a liquid detergent<br />
and water solution until all the dirt is removed. Rinse in clear water to remove the detergent solution. Squeeze the<br />
element (do not twist) to remove the excess water. Wrap the element in a clean cloth and squeeze it (do not twist) until<br />
completely dry.<br />
Re-oil the element by applying engine oil and squeezing it vigorously to distribute the oil. Roll the element in a cloth and<br />
squeeze it (do not twist) to remove the excess oil.<br />
Clean the air cleaner housing and cover being careful not to allow dirt to fall into the carburetor or intake pipe.<br />
