MAINTENANCE
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 15 as a general
maintenance guideline

Air Filter Dust Indicator
The air filter indicator (Figure 54) is attached to the air filter.
When the air filter element is clogged, air intake restriction
becomes greater and the air filter indicator signal shows
RED.
When indicator is red, replace filter immediately.
After changing the air filter,
press
the air filter indicator
button to reset.

AIR CLEANER
Every 250 hours: Remove air cleaner element (Figure 55)
and clean the heavy duty paper element with 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
becomes damaged.
NOTICE
The air filter should not be changed until the indicator
reads “
RED
”. Dispose of old air filter. It may not be
cleaned or reused.

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 air cleaner more
frequently
if these conditions
exist.
Primary and Secondary Air Cleaner Elements
1. Release the latches (Figure 55) that secures the cover
to the air cleaner body.
2. Remove the air cleaner cover and set aside.
3. Remove both the primary and secondary air cleaner
elements.
4. Check the air cleaner daily or before starting the engine
5. Check for and correct heavy buildup of dirt and debris
along with loose or damaged components.
6. To clean the primary element (paper air filter) as
referenced in (Figure 55), 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
2
) through the filter element from the inside out.

7. Clean the secondary element (paper air filter) as
referenced in step 6.
8. Replace both elements if they are damaged or
excessively dirty.
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
Operating the engine with loose or damaged air cleaner
components could allow unfiltered air into the engine
causing premature wear and failure.
