AIR FILTER
It is essential that the air filter is clean and free from dirt and dust. If dirt is allowed to build up it will restrict air flow
to the carburetor and cause poor engine performance and use up more fuel. Inspect the air filter before you
operate the machine. If required clean the air filter. You will need to clean/change the air filter more frequently if
you are operating the engine in very dusty and dry environments.
Never operate the engine without an air filter, or with a damaged air filter, as it will allow dirt to enter the engine,
causing rapid engine wear. This type of damage is not covered under the warranty
A: Air cleaner case
B: Foam Filter
C: Air cleaner cover
Inspection
1. Remove the air filter cover. Be careful to prevent dirt and debris from falling into the air cleaner base.
2. Remove the air cleaner from the air filter base.
3. Inspect the air filter elements. Replace any damaged elements. Clean or replace dirty elements.
Cleaning
1. Remove the air filter cover and foam element, as described in the “INSPECTION” procedure.
2. Remove the foam element from the air cleaner base.
3. Tap the element several times on a hard surface to remove excess dirt. Never try to brush off dirt; brushing will force
dirt into the fibers. Clean the foam element with water and detergent. Leave to fully air dry before reinstalling it.
4. Wipe dirt from the air filter base and clean using a moist rag. Be careful to prevent dirt from entering the air duct that
leads to the carburetor.
5. Reinstall the air filter element, and make sure it is properly positioned. Install the air filter cover and tighten the two
bolts securely.
