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 11 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 38). Check
the air cleaner daily or before starting the engine. Replace
the air cleaner as needed.
Every 100 hours: Remove the air cleaner element and
clean it with a light spray of compressed air, not to exceed
30 psi (205 kPa, 2.1 kgf/cm
CAUTION
Wear protective equipment such as
approved safety glasses or face shields
and dust masks or respirators when
cleaning air filters with compressed air.
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.

(Figure 39). As the air cleaner element becomes clogged,
air intake restriction increases and the indicator signal
shows RED, indicating that the element needs to be
replaced. After replacing the air cleaner element, press the
restriction indicator button to reset the indicator.

NOTICE
DO NOT overservice the air cleaner element.
Overservicing may cause dirt to enter the engine
causing premature wear. Use the dust indicator as
a guide for when to service. The air cleaner element
should not be changed until the indicator displays RED.
NOTICE
DO NOT run the engine with the air cleaner removed
or without an element.
