MAINTENANCE
GENERAL INSPECTION
Prior to each use, the light tower should be cleaned and inspected for defi ciencies. Check for loose, missing or damaged nuts, bolts or other fasteners. Also check for fuel or oil leaks.
Air Cleaner
Check dust indicators on control panel daily or every 10 hours of operation. If light is ON, clean the air cleaner element.
1.Unlatch the holding clips and take out the air cleaner 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 (if present, Deutz/ Lombardini engines has a single element only) after cleaning it 6 times or after one year. Replace the outer element if indicator is red even after cleaning it.
6.If seal washer is damaged or the threads of wing nut are damaged, replace.
7.Remove evacuator valve and clean it with compressed air. Reinstall.
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.
To restart after running out of fuel, squeeze the fuel primer bulb to pump fuel into the engine.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 6.
FLUSHING OUT RADIATOR AND CHANGING COOLANT
WARNING
Allow engine to cool when fl ushing out radiator. Flushing the radiator while hot will damage radiator. In addition, the possibility of hot coolant exists which can cause severe burns.
1.Stop the engine and allow to cool. Tighten valve of the corrosion resistor (if equipped).
2.Turn water filler 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.
