Engine Oil Level - Check
3. Start the engine and run the engine for two
minutes. Perform this procedure in order to ensure
that the lubrication system has oil and that the oil
filters are filled.
4. Inspect the oil filters for oil leaks.
5. Stop the engine. Check the engine oil level. Add
engine oil, if necessary. Refer to Operation and
Maintenance Manual, "Engine Oil Level - Check"

Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.

NOTICE
Perform this maintenance with the engine stopped.
Note: After the engine has been switched OFF, wait
for ten minutes in order to allow the engine oil to drain
to the oil pan before checking the oil level.
1. Maintain the oil level between the "MIN" mark (Y)
and the "MAX" mark (X) on the engine oil dipstick.
Do not fill the crankcase above the "MAX" mark
(X).
If you operate the engine with the oil level above the
"MAX" mark, this may cause your crankshaft and bal-
ance weights to be dipped in oil. If you drive the
crankshaft and balance weights through oil, exces-
sive drag will occur and this will increase the load on
the engine. Air bubbles will be created when the
crankshaft and balance weights are driven through
oil. This will reduce the lubricating characteristics of
the oil and result in a loss of power.

2. Remove the oil filler cap and add oil, if necessary.
Clean the oil filler cap. Install the oil filler cap.
Engine Oil Sample - Obtain
Replacement Program for the
Engine Oil and Filter
The life of the lubricating oil and filter is governed by
the engine load and quality of the gas that is
supplied.
In order to determine the optimum program for the oil
and filter service, use the oil analysis program that
follows.
Initiating an Oil analysis Program
The oil sample must be taken from the mean level in
the engine oil pan. Do not take an oil sample from the
drain plug.
Oil analysis in the first 500 hours will show higher
g01165836
levels of iron and copper than the acceptable
parameters. This is shown in the list that follows. As
the engine continues to operate the levels will drop
within the specified parameters.
Every 250 Hours
Run the engine for the first 500 hours. Replace the
engine oil and the engine oil filter. Every 250 hours
obtain an oil sample.
A trend can be established by analyzing the results of
the oil sampling. Each individual operator can
develop a service program for the engine.
Note: The engine oil and the engine oil filter must be
replaced at 2000 hours.
