6. Check for leaks.
a. Start and run the generator set to allow the oil
pressure to reach the operating range.
b. Check for oil leaks around the oil filter and oil
drain plug.
c. Stop the generator set and recheck the oil level.
Tighten the oil filter to stop any leaks. Add oil to
bring the level up to the F mark on the dipstick.
7. Replace the generator set compartment front
panel.
8. Move the generator set master switch to the AUTO
position to return the unit to standby service.
9. Reinstall the cabinet door.
3.4.4 Low Oil Pressure Shutdown
The low oil pressure shutdown feature protects the
engine against internal damage if the oil pressure drops
below a safe operating level because of oil pump failure
or other malfunction. This shutdown feature does not
protect against damage caused by operating with the oil
level below the safe range—it is not a low oil level
shutdown. Check the oil level regularly and add oil as
needed.
3.5 Air Cleaner Element and
Precleaner
The engine has a replaceable high-density paper air
cleaner element with an oiled-foam precleaner. See
Figure 3-6. Refer to the service views in Section 1.4 for
the air cleaner location.
Check for a buildup of dirt and debris around the air
cleaner system. Keep this area clean.
Note: Operating the engine with loose or damaged air
cleaner components could allow unfiltered air
into the engine causing premature wear and
failure.
Fire.
Can cause severe injury or death.
Do not smoke or permit flames or
sparks near fuels or the fuel system.
WARNING
Servicing the air cleaner. A sudden backfire can cause
severe injury or death. Do not operate the generator set with
the air cleaner removed.
