7. "HOW-TO" MAINTENANCE

ENGINE OIL CHANGE
Change engine oil every 50 hours.
(for a new engine, change oil after 5 hours.)
(a) Drain oil by removing the drain plug and
the oil filler cap while the engine is warm.
NOTE:
Please use a container to dump the
used oil for protecting the environment.
(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 quantity.
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.
SERVICING THE AIR CLEANER
Maintaining an air cleaner in proper
condition is very important. Dirt induced
through improperly installed, improperly
serviced, or inadequate elements
damages and wears out engines.
Always keep the element clean.
(a) Take out the air cleaner, clean it well
in kerosene and dry it.
(b) After wetting the element by clean
engine oil squeeze it tight by hand.
(c) Lastly, put the element in the case
and install it securely.
