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 17 .
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.
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.
Tighten both cocks and replace the overflow tank.
Replace with coolant as recommended by the engine
manufacturer.
Close radiator cap tightly.
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.
WARNING
Allow engine to cool when flushing out
radiator. Flushing the radiator while hot
could cause serious burns from water or
steam.
RADIATOR CLEANING
The radiator (Figure 41) should be sprayed (cleaned) with
a high pressure washer when excessive amounts of dirt
and debris have accumulated on the cooling fins or tube.
When using a high pressure washer, stand at least 5 feet
(1.5 meters) away from the radiator to prevent damage to
the fins and tube.

GENERATOR STORAGE
For long term storage of the generator the following is
recommended:
Drain 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.
