Fuel Tank Inspection
In addition to cleaning the fuel tank, the following components should be inspected for wear:
Rubber Suspension — look for signs of wear or deformity due to contact with oil. Replace the rubber suspension if necessary.
Fuel Hoses — inspect nylon and rubber hoses for signs of wear, deterioration, and hardening.
FuelTank Lining — inspect the fuel tank lining for signs
of excessive amounts of oil and other foreign matter.
Replacing Fuel Filter
Replace the fuel filter cartridge with a new one every 500 hours.
Loosen the drain plug at the lower top of the fuel filter. Drain the fuel in the fuel body together with the mixed water. DO NOT spill the fuel during disassembly.
Vent any air.
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. Refer to the Cummins engine manual for details.
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. The oil level must be between the two notches on the dipstick.
Replacing Oil Filter
1.Remove the old oil filter.
2.Apply a film of oil to the gasket on the new oil filter.
3.Install the new oil filter.
4.After the oil filter 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.
Flushing Out Radiator and Replacing Coolant
WARNING
Allow engine to cool before flushing out radiator. Flushing the radiator while hot could cause serious burns from water or steam.
1.Remove radiator cap. Remove coolant drain plug located on side of generator. Place coolant drain lever in the open position to drain coolant.
2.Flush the radiator by running clean tap water through radiator until signs of rust and dirt are removed. Do not clean radiator core with any objects, such as a screwdriver.
3.Check hoses for softening and kinks. Check clamps for signs of leakage.
4.Move lever to the closed position and reinstall coolant drain plug.
5.Replace with coolant as recommended by the engine manufacturer.
6.Close radiator cap tightly.
Generator Storage
For long term storage of the generator the following is recommended:
1.Drain the fuel tank completely.Treat with a fuel stabilizer if necessary.
2.Completely drain the oil from the crankcase and refill, if necessary, with fresh oil.
3.Clean the entire generator, inside and outside.
4.Disconnect the battery.
5.Make sure engine coolant is at proper level.
6.Cover the generator and store in a clean, and dry place.
