ENGINE
ENGINE OIL
Only use high quality detergent oil rated with API
service classification SF, SG or SH. Select the oil’s
viscosity grade according to your expected operating
temperature.
NOTE: Although multi-viscosity oils (SE30, 10W30,
etc.) improve starting in cold weather, these multi­
viscosity oils will result in increased oil consumption
when used above 32° F. Check your oil level more
frequently to avoid possible engine damage from
running low on oil.
Your four-cycle engine will normally consume some
oil—^therefore, check engine oil level regularly approx­
imately every five hours of operation and before each
usage. Stop engine and wait several minutes before
checking oil level. With engine level, the oil must be to
FULL mark on dipstick (refer to figure 10). Change
engine oil after the first five hours of operation, and
every twenty-five hours thereafter.
To Drain Oil:
® Drain oil while engine is warm.
a. Remove oil drain cap. Refer to figure 10. Catch
oil in a suitable container.
b. When engine is drained of ail oil, replace drain
cap securely.
® Refill with fresh oil. Refer to GAS AND OIL FILL­
UP section.
® Replace dipstick.
