General Inspection

Prior to each use, the generating set should be cleaned and inspected for deficiencies. Check for loose, missing or damaged nuts, bolts or other fasteners. Also check for fuel or oil leaks.

Air Cleaner

Every 50 hours: If dust indicator is red, clean the air cleaner element.

Outer Element:

1.Loosen wing bolt, remove dust cup, then remove wing nut and take out element.

2.Clean the inside of the body and cover using a damp cloth.

3.Blow dry with compressed air (0.69Mpa [7kgf.cm2, 99.4 PSI] maximum) against the side of the element along the pleats. Then blow dry against outside along the pleats, then against inside again.

4.Remove one seal each time the element is cleaned.

5.Replace the outer element after cleaning it 6 times or after one year. Replace the outer element if indicator is red even after cleaning it.

6.Check the inner cylinder element clamping nut for looseness, and retighten if necessary.

7.If seal washer is damaged or the threads of wing nut are damaged, replace.

8.Remove evacuator valve and clean it with compressed

air. Reinstall.

Inner element (if equipped)

1.Remove the cover and outer element, then remove the inner element.

2.Cover the air connector opening (outer side) with clean cloth or cloth tape.

3.Clean the inside of the body. Remove air connector opening protection.

4.Install a new inner cylinder element to the cylinder and tighten the nut.

5.Install element.

6.After replacing the element, press the button of the dust indicator to return the red piston to its original position.

Fuel Addition

Add diesel fuel (the grade may vary according to season and locations). Always pour through the mesh filter.

Removing Water from the 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 greater the empty volume inside the tank, the easier it is for water to condense. This can be reduced by always keeping the tank as full as possible.

Air Removal

If air enters the fuel injection system of a diesel engine, starting becomes impossible. After running out of fuel, or after disassembling the fuel system, bleed the system according to the following procedure.

To restart after running out of fuel, turn the key switch to the “START” position for 15-30 seconds. Try again, if needed. This unit is equipped with an automatic air bleeding system.

Service Daily

If engine is operating in very dusty and dry grass conditions, a clogged air cleaner will result in high fuel consumption, loss of power and excessive carbon buildup in the combustion chamber.

Cleaning the Fuel Strainer

Clean the fuel strainer if it contains dust or water. Remove dust or water in the strainer cap and wash it in diesel. Securely fasten the fuel strainer cap so that fuel will not leak. Check the fuel strainer every 200 hours of operation or once a month.

Check Oil Level

Check the crankcase oil level prior to each use, or when the fuel tank is filled. Insufficient oil may cause severe damage to the engine. Make sure the generator is level. The oil level must be between the two notches on the dipstick as shown in Figure 14, page 39.

Flushing Out Radiator and Changing Coolant

1.Stop the engine and allow to cool. Tighten valve of the corrosion resistor (if equipped).

2.Turn water filer cap slowly and remove it.

3.Prepare a container to catch the coolant, then open drain plug of the radiator or heat exchanger and drain plug of the engine, and drain the coolant.

4.After draining the coolant, close drain plugs and fill with tap water.
