Oil Filter Change; Gaseous Fuel System - Kohler 15RYG Operation

10. Stop the generator set. Check the oil level. Add oil,
as necessary, to bring the level up to the Full mark.
Note: Too high an oil level causes high oil
consumption and engine carbonizing. Too
low a level damages the engine.
Note: Do not pollute the environment. Dispose of
used engine oil and other contaminants in a
safe, approved manner.

Oil Filter Change

Replace the oil filter at the interval specified in the
service schedule. Change the oil filter more frequently if
the generator set operates under dirty, dusty conditions.
Refer to the following procedure. See Section 1 for oil
filter location.
Oil Filter Change Procedure
1. Loosen the oil filter by turning it counterclockwise.
Remove the oil filter and use rags to clean up
spilled oil. Dispose of the oil filter in an approved
manner.
2. Clean the contact surface of the oil filter adapter.
3. Lightly lubricate the gasket surface of the new filter
with fresh engine oil. Thread the filter on the
adapter until the gasket makes contact and
hand-tighten the filter an additional one-half turn.
Wash hands after any contact with engine oil.
Note: If also performing an oil change, skip steps 4
and 5 and go back to oil change procedure.
4. Start the generator set and check for oil leaks.
5. Stop the generator set. Check oil level. Add oil, as
necessary, to bring level up to Full mark.

3.5 Gaseous Fuel System

The gaseous fuel system utilizes a fuel valve (with
solenoid) to control the fuel flow to the fuel regulator.
The generator-mounted
pressure as fuel passes to the mixer. See Figure 3-5.
The mixer controls the ratio of fuel to air under varying
loads and speed conditions.
receives fuel in a gaseous state, it does not need to
vaporize the fuel.
Fuel regulators are compatible with both natural gas and
LP gas. See Figure 3-6.
instructions found on the hang tag attached to the
generator set. If the set operates on LP gas, follow the
instructions in the Installation Manual to remove the
internal spring from the gas regulator and adjust the fuel
mixture. See the List of Related Literature in the
Introduction to this manual for the document number.
