3.1 Air Cleaner Service

Replace the air cleaner element at the intervals shown in
the service schedule. Service the air cleaner more often
if the generator set operates under dusty or dirty

damage and increased fuel consumption. When
servicing, clean the air cleaner breather pipe and
remove dust and foreign matter from the air cleaner
housing. See Section 1 for the air cleaner location and
the following procedure.
Air Cleaner Service Procedure:

the base. Check that the clamps are tight on the
inlet/outlet connections.
8. Install the air cleaner element.
9. Position the cover over the base and tighten using
the air cleaner clips.
Note: 15 and 20 kW models require positioning the
