KD1800/KD6 — MAINTENANCE (ENGINE)

4.If the engine oil level is too low, remove the engine oil filler cap Figure 9, and fill to the correct operating level.

Figure 9. Engine Oil Filler Hole

CAUTION:

zEngine oil should be MIL-L2104C or have properties of API classification CD grades or higher.

Fuel Lines

Every 50 hours: Check the fuel lines and associated clamp bands every 50 hours of operation.

1.If the rubber fuel lines and clamp bands become worn, replace them immediately. Replace all rubber fuel lines every two years.

Replacing the Fuel Filter

Every 400 hours: Replace the fuel filter (Figure 11) every 400 hours.

Figure 11. Fuel Filter

zWhen changing the engine oil, use a oil with a viscosity appropriate for the atmospheric temperature at the site. Use SAE-30 oil in the summer, SAE-20 in the winter, or all season SAE 10W-30 oil which offers stable viscosity at various ambient temperatures. See Table 4 .

zWhen different type oil brands are used, be sure to drain all the previous oil before adding the new engine oil.

Oil Cartridge

Every 200 hours: Replace the engine oil filter cartridge (Figure 10) after every 200 hours of operation.

Figure 10. Oil Filter Cartridge

1.Remove the old oil filter cartridge with a filter wrench.

2.Apply a film of oil to the gasket for the new cartridge.

3.Screw the new cartridge in by hand. DO NOT use the filter wrench to tighten the new filter.

4.Run the engine for a few minutes, check for leaks. Check engine oil level, add oil if necessary.

Fuel Addition

When adding diesel fuel to the fuel tank, the grade may vary according to season and locations. Typically use No.2 diesel fuel will filling the fuel tank. Always pour through a mesh filter, this will prevent sand and dirt from entering the fuel system.

Removing Water (Condensation) from the Fuel Tank After prolonged use, water and other impurities accumulate in the bottom of the tank. Occasionally remove the drain cock and drain the contents. During cold weather, the more empty area inside the tank, the easier it is for water to accumulate. This can be reduced by always keeping the tank as full as possible.

NOTE

The fuel tank for this generator is contained within the trailer section of the Modular Light Tower (MLT).
