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. See the John Deere 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. Make sure the generator is level.The oil level must be between the two notches on the dipstick as shown in Figure 33.
Replacing Oil Filter
■Remove the old oil filter.
■Apply a film of oil to the gasket on the new oil filter.
■Install the new oil filter.
■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
■Replace the fuel filter cartridge with new one every 500 hours or so.
■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.

Flushing Out Radiator and Replacing Coolant
■Open both cocks located at the crankcase side and at the lower part of the radiator and drain coolant. Open the radiator cap while draining. Remove the overflow tank and drain.
■Check hoses for softening and kinks. Check clamps for signs of leakage.
■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.
■Tighten both cocks and replace the overflow tank.
■Replace with coolant as recommended by the engine manufaturer.
■Close radiator cap tightly.
WARNING - BURN HAZARDS
Allow engine to cool when flushing out radiator. Flushing the radiator while hot could cause serious burns from water or steam.
Generator Storage
For longe term storage of the generator the following is recommended:
■Fill the fuel tank completely. Treat with a fuel stabilizer if necessary.
■Completely drain the oil from the crankcase and refill if necessary with fresh oil.
■Clean the entire generator, internal and external.
■Cover the generating set and store in a clean, dry place.
■Disconnect the battery.
■Make sure engine coolant is at proper level.
■If generator is mounted on a trailer, jack trailer up and place on blocks so tires do not touch the ground or block and completely remove the tires.
