Air Filter Inspection
1. Unscrew the outer wing nut and remove the air cleaner cover.
2. Remove the inner wing nut and both air filter elements.
3. Separate both air filter elements and carefully check them for holes
or tears. Replace the filter elements if they are damaged.
4. If the air filter elements are dirty, clean them as described below.
5. Wipe dirt from the inside of the air cleaner housing and cover. Be
careful to prevent dirt from entering the air duct that leads to the
carburetor.
6. Install the foam element over the paper element, and install the
assembled air filter. Secure the air filter with the inner wing nut.
Make sure the rubber washer is in place under the filter elements.
7. Install the air cleaner cover, and secure with the outer wing nut.
NOTICE
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.
Air Filter Cleaning
A properly maintained air filter will help prevent dirt from entering your
engine. Dirt entering the carburetor can be drawn into small passages
in the carburetor and cause premature engine wear. These small
passages can become blocked, causing starting or running problems.
Always use an air filter specified for your engine to ensure it seals and
performs as designed. You will need to clean the filter more frequently
if you operate the engine in very dusty conditions.
1. To clean the paper filter element, tap the element lightly several
times on a hard surface to remove excess dirt, or blow compressed
air [not exceeding 30 psi (207 kPa)] through the filter element from
the inside out.
Never try to brush the dirt off; brushing will force dirt into the paper
fibers. Replace the paper element if it is excessively dirty or
damaged.
2. To clean the foam filter
element, wash the
element in a solution of
household detergent and
warm water, then rinse
thoroughly, or wash in
nonflammable solvent.
3. Allow the foam filter
element to dry
thoroughly.
4. Soak the foam filter element in clean engine oil and squeeze out
the excess oil.
NOTICE
Excess oil will restrict air flow through the foam filter element and
may transfer to the paper filter element, soaking and clogging it.
5. Reassemble the air filter as shown.
