authorized service center for repair if there are any defect or if the sprocket is worn
out more than 0.5 mm.

from falling into the carburetor.
2. Loosen the bolt, and remove the air cleaner cover.
3. Remove the air cleaner.
NOTE:
• During cleaning, cover the opening with a clean cloth to prevent dirt or foreign
materials from falling into the carburetor.

4. Tap it or clean it with a brush or air compressor to remove the dirt.
NOTE:
• Depending on the country there are two types of air cleaner material, nylon or

does not run well even after the cleaning, replace the air cleaner.
