NOTE
SAE10W-30 is recommended for general use. Other viscosities may be
used based on the average temperature range as shown.
Do not tilt the water pump when adding engine oil. This could result in
overfilling and damage to the engine.
Use high quality 4-stroke engine oil, certified to meet or exceed API
standard SG, SF, SAE ratings with strong detergents. Using non-
detergent or 2-stroke oil could shorten the engine's working life.
Do not mix different engine oils.
Handle and store the engine oil with care, avoid getting dirt or dust into
the engine oil.
Before the engine oil falls below the safety margin, the low oil alert
system will automatically shut off the engine. The low oil light will turn on.
To avoid the inconvenience of unexpected engine shutoff, check the
engine oil level as often as possible.
