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.
Fuel Tank 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.
MAINTENANCE
FLUSHING OUT RADIATOR AND REPLACING
COOLANT
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.
WARNING
Allow engine to cool before flushing out
radiator. Flushing the radiator while hot
could cause serious burns from water or
steam.
