MAINTENANCE

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 28.

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 59) 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.
