The output from the electronic oil level sensor shows the oil level on the
STATUS synoptic. The oil level indication is either LOW (amber) or
NORM (green), and is only available when the engines are not in
operation. Each engine also has a graduated oil level sight glass on the
outboard side of the engine as a secondary method of examining the oil
level (Figure 4-7). The sight glass is calibrated to the same ground
attitudes as the electronic oil level sensor.

SERVICING THE ENGINE OIL SYSTEM

If possible, add oil only after the engine is shut down for more than
5 minutes, but not more than 30 minutes. If you add oil to a cold engine,
it is possible to have too much oil in the tank when the oil temperature
increases. This will not damage the engine, but it is not recommended.

It is permissible to dispatch with an amber LOW oil
level on the STATUS page as long as the sight glass on
the outboard side of the engine shows oil above the add
line.
Do not get engine oil on your skin or in your eyes.
Wear gloves and safety glasses. Obey all health and
safety instructions. If you get engine oil in your eyes,
get medical aid immediately.
Do not touch the engine when it is hot. The engine
stays hot after shutdown. A hot engine can cause
burns.
