Allow engine to cool when flushing out
radiator. Flushing the radiator while hot
could cause serious burns from water
o r
steam.
WARNING - BURN HAZARDS
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 block so tires do touch the ground or remove
tires.
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 (Table 13 for correct mixture).
 Close radiator cap tightly.
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 15-30 seconds. Try again, if needed. This
unit is equipped with an automatic air bleeding system.
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 31).
Replacing Oil Filter
 To remove the oil filter, grip the filter body and turn
counter-clockwise
 Apply a film of oil to the rubber seal gasket.
 Place the oil filter body onto the oil filter spindle by turning
clockwise. DO NOT over tighten.
 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.
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.
