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 16 as a general
maintenance guideline Engine Side (Refer to the Engine
Instruction Manual).
AIR CLEANER
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.
Every 250 hours: Remove the air cleaner element
(Figure 65) and clean the heavy-duty paper element with
a light spray of compressed air. Replace the air cleaner
as needed.
This Isuzu diesel engine is equipped with a replaceable,
high-density, paper air cleaner element. This air cleaner is
also equipped with an inner element (secondary) that is
used as a backup filter should the primary element become
damaged.
CAUTION
Wear protective equipment such as
approved safety glasses or face shields
and dust masks or respirators when
cleaning air filters with compressed air.

Operating the engine with loose or damaged air cleaner
components could allow unfiltered air into the engine
causing premature wear and failure.

as referenced in Figure 65, tap the filter element
several times on a hard surface to remove dirt, or
blow compressed air, not to exceed 30 psi (207 kPa,
