CHECK OIL LEVEL
Check the crankcase oil level prior to each use, or when the 
fuel tank is fi lled. Insuffi cient 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 29.
Replacing Oil Filter
 Remove the old oil fi lter.
 Apply a fi lm of oil to the gasket on the new oil fi lter.
 Install the new oil fi lter.
 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 overfl ow 
tank and drain.
 Check hoses for softening and kinks. Check clamps for
signs of leakage.
 Tighten both cocks and replace the overfl ow 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 fl ushing out 
radiator. Flushing the radiator while hot 
could cause serious burns from water or 
steam.
RADIATOR CLEANING
The radiator (Figure 61) should be sprayed (cleaned) with 
a high pressure washer when excessive amounts of dirt 
and debris have accumulated on the cooling fi ns 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 fi ns 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 refi ll 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.
