CHECK OIL LEVEL
NOTE
There are two methods for checking engine oil level on the AVDS-
1790 series engine. The first method is designated as a "Before
Operations" oil check and is taken with the engine stopped. The
second method is designated as a "During Operations" oil check and
is taken with the engine running.
1. Before Operations oil check:
It is imperative to check the oil level before operating the engine. This Before Operations
check must only be performed when the engine has been shut down for a minimum of 2 hours
or a faulty reading will result. There are three key requirements that must be met to assure
accurate reading of the oil level gauge rod:
a. The engine must have been shut down for a minimum of 2 hours.
b. The engine must be flat and level.
c. The correct side of the gauge rod must be read.

CORRECT SIDE OF GAUGE ROD FOR BEFORE CHECK
Example
Read the oil gauge rod before you add any oil. Add oil based on your
reading. After adding oil, do NOT check with the gauge rod using the
"Before Operations" check method unless the engine has been run
then shut down for a minimum of 2 hours. Instead, use the "During
Operations" method to check the oil level after the engine has been
run and warmed up to normal operating temperature.
2. During Operations oil check:
During operations it is critical to maintain proper engine oil level. There are four key
requirements that must be met to assure accurate reading of the oil level gauge rod for During
Operations checks.
a. The oil temperature must be less than 140 F (60 C).
b. The engine must have been idling for at least 5 minutes.
c. The engine must be level and flat.
d. The correct side of the gauge rod must be read.
