General Inspection
Prior to each use, the generator should be cleaned and inspected for deficiencies. Check for loose, missing or damaged nuts, bolts, and other fasteners. Also check for fuel, oil, and coolant leaks. Use Table 14 as a general maintenance guideline. For engine maintenance, refer to the engine maintenance manual.
Air FILTER
Every 250 hours: Remove air filter element (Figure 33) and clean the filter element with low pressure compressed air. Air pressure must not exceed 30 psi (207 kPa). The filter can be cleaned and reused for up to six times if properly cleaned. Replace air filter if rips or tears are detected while cleaning.
Air Filter Dust Indicator
The air filter indicator (Figure 33) 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.

NOTICE
The air filter should be changed more frequently in dusty operating conditions.
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.
Fuel Addition
Add diesel fuel (the grade may vary according to season and locations).
Removing Water from the Fuel Tank
After prolonged use, water and other impurities accumulate in the bottom of the tank. Occasionally inspect the fuel tank for water contamination and drain the contents if necessary.
During cold weather, the more empty volume inside the tank, the easier it is for water to condense. This can be reduced by keeping the tank full with diesel fuel.
Cleaning Inside the Fuel Tank
If necessary, drain the fuel inside the fuel tank completely. Using a spray washer (Figure 34) wash out any deposits or debris that have accumulated inside the fuel tank.
