Engine oil capacity is 600 ml (approx. 20 oz.). Do not over-fill. Use a
4-stroke, or an equivalent high detergent, premium quality motor oil
certified to meet or exceed U.S. automobile manufacturer's require-
ments for service classification SG, SF. Motor oils classified SG, SF
will show this designation on the container.
NOTE: Please dispose of used motor oil in a manner that is friendly to
the environment. Take it to a recycling center or other collection center.
DO NOT use non-detergent oil or 2-stroke engine oil. It could shorten
the engine's service life.
Changing Engine Oil
Shut off the engine and remove the ignition key before performing
any maintenance. To prevent accidental start-up, disconnect the
spark plug boot.
Periodic inspection and adjustment of the engine is essential if high
level performance is to be maintained. Regular maintenance will also
ensure a long service life. The required service intervals and the type
of maintenance to be performed are described in the table above.
Follow the hourly or calendar intervals, whichever occur first. More
frequent service is required when operating in adverse conditions.
Check oil level before each use and every 5 operating hours when the
engine is warm. Refer to Checking and Adding Oil in the Assembly
Section.
Change the oil after the first 5 operating hours and every 50 operating
hours thereafter. Engine should still be warm but NOT hot from recent
use.
