DCA-60SSIU — MAINTENANCE
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 50 hours: Remove air cleaner element and clean heavy duty paper element with kerosene, or foam element with liquid detergent and hot water. Wrap foam element in a cloth and squeeze dry. For heavy duty paper element, wipe excess kerosene with towel.
The air cleaner is equipped with an indicator. After the dirty air cleaner has been replaced, press the dust indicator button to reset the indicator.
Fuel Addition
Add diesel fuel (the grade may vary according to season and locations). Always pour through the mesh filter.
Removing Water 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 volume inside the tank, the easier it is for water to condense. This can be reduced by keeping the tank full as much 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 switch to the “ON” position for
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 in high fuel consumption.
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 gasoline. 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 32, page 43.
Replacing Oil Filter
1.Detach the oil filter cartridge with a filter wrench.
2.Apply a film of oil to the gasket for the cartridge.
3.Screw in the cartridge by hand. When the gasket is in contact with the seal surface, tighten the cartridge one or two more times by hand.
4.After the oil cartridge has been replaced, the engine oil will drop slightly. Run the engine for a while and check for leaks before adding more oil if needed. Clean excessive oil from engine.
Replacing Fuel Filter
1.Replace the fuel filter cartridge with new one every 400 hours or so.
2.Apply fuel oil thinly over the gasket and
3.Vent any air.
4.Fuel Injection Nozzle
5.Use an injection nozzle tester to check the static injection starting pressure and the fuel spray conditions.
6.Abnormal fuel consumption will lead to a lowered output and blackish exhaust smoke. The required injection starting pressure should be 14.7MPa (150kg/cm2, 2130psi).
