8."HOW-TO" MAINTENANCE
1.ENGINE OIL CHANGE
Change engine oil every 50 hours.
(for new engine, change oil after 20 hours.)
(a)Drain oil by removing the drain plug and the oil filler cap while the engine is warm.
(b)Reinstall the drain plug and fill the en- gine 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 5. 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.
2.SERVICING THE AIR CLEANER t
Maintaining an air cleaner in proper condi- tion is very important. Dirt induced through improperly installed, improperly serviced or inadequate elements damages and wears out engines. Keep the element clean ac- cording to the chart on page 21.
PROCEDURE:
(a)Unhook the cover and remove the cleaner element.
(b)Inner element: Wash the element with kemsene, then soak it in mixed oil (Kerosene (3 parts) : Engine oil (1 part)). Drain the mixed oil.
(c)Outer element: Wash the element with kerosene, then dip it into the mixed oil (Kerosene (3 parts): Engine oil (1 part)). Squeeze out the mixed oil. (Do not twist.)
