GENERAL INSPECTION
Prior to each use, the generator should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts or other fasteners. Also check for
fuel, oil, and coolant leaks. Use Table 14 as a general
inspection and maintenance guideline. For more detailed
engine maintenance instructions, refer to the engine
owner's manual.
ENGINE AIR CLEANER
This Kubota diesel engine is equipped with a replaceable,
high-density, paper air cleaner element (Figure 58). The air
cleaner is also equipped with an inner (secondary) element
that is used as a backup filter should the primary element
become damaged. Check the air cleaner daily or before
starting the engine. Replace the air cleaner as needed.
NOTICE
If the engine is operating in very dusty or dry grass
conditions, a clogged air cleaner will result. This can
lead to a loss of power, excessive carbon buildup in
the combustion chamber, and high fuel consumption.
Change the air cleaner more frequently if these
conditions exist.

Wear protective equipment such as
approved safety glasses or face shields
and dust masks or respirators when

1. Release the latches that secure the cover to the air
cleaner body (Figure 58).
2. Remove the air cleaner cover (Figure 58) and set it
aside.
3. Remove both the primary and secondary air cleaner
elements (Figure 58).
4. Check for and correct heavy buildup of dirt and debris
along with loose or damaged components.
NOTICE
Operating the engine with loose or damaged air cleaner
components could allow unfiltered air into the engine
causing premature wear and failure.
5. To clean the primary element (paper air filter) as
shown in Figure 58, tap the filter element several times
on a hard surface to remove dirt, or blow compressed
air, not to exceed 30 psi (207 kPa, 2.1 kgf/cm
the filter element from the inside out.
6. Clean the secondary element (paper air filter) as
described in step 5.
7. Replace both elements if they are damaged or
excessively dirty.
8. Clean the inside of the air cleaner body (Figure 58).
9. Reinstall the primary and secondary air filter elements
back into the air cleaner body.
10. Reinstall the air cleaner cover and secure with latches.
