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 Engine Side (Refer to the Engine
Instruction Manual).
Air Filter Dust Indicator
NOTICE
The air filter should not be changed until the indicator
reads "RED." Dispose of the old air filter. It may not be
cleaned or reused.
The air filter indicator (Figure 62) 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 the indicator is red, replace the filter
immediately. After changing the air filter, press the air filter
indicator button to reset.

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 and
clean the heavy duty paper element with a light spray of
compressed air. Replace the air cleaner as needed.
This John Deere 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

Primary and Secondary Air Cleaner Elements
1. Release the latches (Figure 63) that secure the cover
to the air cleaner body.
2. Remove the air cleaner cover and set it 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.
NOTICE
Operating the engine with loose or damaged air cleaner
components could allow unfiltered air into the engine
causing premature wear and failure.
6. To clean the primary element (paper air filter)
as referenced in Figure 63, 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 ) through the filter element from the inside out.
