AIR CLEANER
A dirty air cleaner will restrict air flow to the carburetor, reducing engine
performance. If you operate the powerhead in very dusty areas, clean the
air filter element more often than specified in the MAINTENANCE
SCHEDULE.
Operating the engine without an air filter element, or with a damaged air
filter element, will allow dirt to enter the engine, causing rapid engine wear.
This type of damage is not covered under the Distributor's Limited Warranty
(U.S.) / Distributor's Warranty (CA.).
Inspection
1. Move the choke lever to the CLOSED (upwards) position.
2. Remove the air cleaner cover by unhooking the upper tab on the top
of the air cleaner cover and its two lower tabs.
3. Check the air cleaner element for deterioration, damage, dirt or
obstruction. Clean the air cleaner element, if it is dirty or replace it if it
is damaged.
4. Reinstall the air cleaner element. Make sure it is properly positioned
and seated against the air cleaner case.
5. Reinstall the air cleaner cover by inserting the lower tabs, then insert
the upper tab.
Cleaning
1. Clean in warm soapy water, rinse and allow to dry thoroughly. Or use
a high flash point solvent, allow to dry. Dip the element in clean
engine oil and squeeze out all the excess.
The engine will smoke during initial startup if too much oil is left in
the foam.
Do not install a dry air filter without any oil applied. Doing so will allow
dust to enter the engine, resulting in rapid engine wear, which is not
covered under the Distributor's Limited Warranty (U.S.) / Distributor's
Warranty (CA.).
