As the element of the air cleaner employed on this engine is a dry type, never apply oil to it.

1. Open the evacuator valve once a week under ordinary conditions-or daily when used in a dusty place-to get rid of large particles of dust and dirt.

2. Wipe the inside air cleaner clean with cloth or the like if it is dirty or wet.

3. Avoid touching the element except when cleaning.

4. When dry dust adheres to the element, blow compressed air from the inside turning the element.; Pressure of compressed air must be under 205kPa (2.1kgf/cm2, 30psi).

5. When carbon or oil adheres to the element, soak the element in detergent for 30 minutes, then wash it several times in water, rinse with clean water and dry it naturally.

6. After element is fully dried, inspect inside of the element with a light and check if it is damaged or not. (referring to the instructions on the label attached to the element.)

7. Replace the element every year or every six cleanings.

Measure tension with a sonic tension meter

Measurement done properly according to the operation manual of the device being used

Measurement done immediately after installing the belt without rotating the pulleys

Fuel filter cartridge replacement

Replace the fuel filter cartridge with a new one

Apply fuel oil thinly over the gasket

Tighten the cartridge into position by hand-tightening only
