(b)Reinstall the drain plug and fill the engine with oil until it reaches the upper level on the oil filler cap.

■Use fresh and high quality lubricating oil to the specified level as directed on page 7. If contaminated or deteriorated oil is used or the quantity of the engine oil is not sufficient, the engine damage will result and its life will be greatly shortened.

Dirt induced through improperly installed, improperly serviced or inadequate elements damages and wears out engines. Keep the element always clean.

(a)Remove the bolt of air cleaner cover. (RGX7100, 7800) Remove the air cleaner cover and cleaner element.

(b)Urethane form : Wash urethane form element in kerosene or diesel fuel. Then saturate the element in a mixture of 3 parts kerosene or diesel fuel and 1 part engine oil.

Squeeze the element to remove the mixture and install it in the air cleaner.

NOTE :

Instead of washing oil (kerosene), it is possible to wash the urethane foam element in a solution of mild detergent and warm water.

Then rinse the element thoroughly in clean water.

Allow the element to dry thoroughly. Soak the element in clean engine oil and squeeze out excess oil.
