"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.
