AIR FILTERING SYSTEM
A dirty air filter will restrict air flow to the carburetor,
reducing engine performance. If you operate the machine
in very dusty areas, clean the air filter more often than
specified in the maintenance schedule.
The air filter element should be checked every day,
cleaned every 3 months or 50 hours of operation, and
replaced once a year or every 300 hours of operation.
Each time you service the air filtering system, make sure
all connections and flanges are air tight. Replace all
damaged parts.
Periodically check the connections for wear or damage.
Check to make sure all connections are tight.
Do the following to clean or replace the filter elements.
Paper Filter Element

been in the machine for one year.

Cleaning the Element
1. Check the dirty element for damage.
2. Check the rubber seal on the end. Push the rubber
seal with your finger. If the rubber seal feels hard and
does not move back to its original shape, discard the
element.
3. Inspect the paper air filter element, and replace it if it
is damaged. Always replace the paper air filter
element at the scheduled interval.
4. Clean the paper air filter if it is to be reused.
Tap the paper air filter element several times on a
hard surface to remove dirt. Never try to brush off
dirt; brushing will force dirt into the fibers. If most of
the dirt and dust is dry, remove the loose dirt with
compressed air. Always wear face protection
when using compressed air.

and cover, using a moist rag. Be careful to prevent
dirt from entering the carburetor air duct.
