*1 Replace engine oil anf filter at 100 hours, first time only.
*2 Add "Supplemental Coolant Addatives (SCA'S)" to recharge the engine coolant.
*3 Replace primary air filter element when restriction indicator shows a vaccum of 625 mm (25 in. H20).
*4 If blowby hose needs to be replaced, ensure that the slope of the bloby hose is at least a 1/2 inch per foot, with no sags or dips that could collect moisture and/or oil.
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.
Engine Side (Refer to the Engine Instruction Manual)
Air Cleaner
Every 250 hours: Remove air cleaner element and clean the heavy duty paper element with light spray of compressed air. Replace the air cleaner as needed.
Air Cleaner with Dust Indicator
This indicator is attached to the air cleaner. When the air cleaner element is clogged, air intake restriction becomes greater and the dust indicator signal shows RED meaning the element needs changing or service. After changing the air element, press the dust indicator button to reset the indicator.
Service Daily
If the engine is operating in very dusty or dry grass conditions, a clogged air cleaner will result.This can lead to
aloss of power, excessive carbon buildup in the combustion chamber and high fuel consumption. Change air cleaner more frequently if these conditions exists.
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 required.
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.
