OPERATING THE GENERATOR 19 ENGLISH OPERATING THE GENERATOR CAUTION To avoid personal injury: A Read " SAFETY PRECAUTIONS" in the front of this manual. A Read the danger, warning and caution labels located on the generator. A To avoid the danger of exhaust fume poisoning, do not operate the engine in a closed building without proper ventilation. A Always turn OFF the circuit breaker before starting the generator. A Turn OFF all switches on the electrical devices.
ENGLISH 20 OPERATING THE GENERATOR 3. Ensure that the fuel lever is set to the "OPEN" Position. (1) Fuel lever (2) Fuel filter pot (A) "OPEN" 4. Insert the key into the main switch and turn it "ON". 5. Check the battery charge lamp and oil pressure lamp are ON. 7. Turn the key to the "START" position and release when the engine starts.
C Warm-up in cold ambient temperatures In cold weather, the engine oil may be cold with increased viscosity. This can delay oil circulation or abnormally low oil pressure for some time after engine start-up. This can result trouble in the lubrication circuit or damage to the engine moving parts. To prevent the above problems, perform the following instructions: Warm up the engine at rated revolution with no load.
ENGLISH 22 OPERATING THE GENERATOR B Stopping the Engine 1. Turn OFF all electrical device switches for connected loads. 2. Turn OFF the circuit breakers. 3. Allow the engine to run with no load for about 5 minutes before stopping the engine completely. 4. Turn the main switch (key) to the "OFF" position. B If the Engine Fails to Stop in the Usual Procedure (EMERGENCY STOP) If the engine does not stop after turning the key switch to "OFF" position, take the following (EMERGENCY STOP) procedure.
23 SERVICE INTERVALS Observe the following for service and maintenance. The lubricating oil change intervals listed in the table below are for Classes CF, CE and CD lubricating oils of API classification with a low-sulfur fuel in use. If the CF-4 or CG-4 lubricating oil is used with a high-sulfur fuel, change the lubricating oil at shorter intervals than recommended in the table below depending on the operating condition. Interval No.
ENGLISH 24 SERVICE INTERVALS For North American market C Engine Oil: A Oil used in the engine should have an American Petroleum Institute (API) service classification and Proper SAE Engine Oil according to the ambient temperatures as shown P27. A Refer to the following table for the suitable API classification engine oil according to and the fuel. Fuel used Engine oil classification (API classification) Ultra Low Sulfur Fuel [<0.
25 PERIODIC SERVICE B Fuel Fuel is flammable and can be dangerous. You should handle fuel with care. C Fuel level check and refueling 1. Check to see that the fuel level is above the lower limit of the fuel level gauge. 2. If the fuel is too low, add fuel to the upper limit. Do not overfill. CAUTION To avoid personal injury: A DO NOT mix gasoline or alcohol with diesel fuel. This mixture can cause an explosion. A Be careful not to spill fuel during refueling.
ENGLISH 26 PERIODIC SERVICE Fuel tank capacity L (U.S.gal.) Model C Checking the fuel pipes Capacity GL6000, GL7000 [Engine model : Z482] GL9000, GL11000 [Engine model : D722] 28 (7.4) C Air bleeding the fuel system CAUTION To avoid personal injury; A Do not bleed a hot engine as this could cause fuel to spill onto a hot exhaust manifold creating a danger of fire.
C Cleaning the fuel filter pot Every 100 hours of operation, clean the fuel filter in a clean place to prevent dust intrusion. 1. Close the fuel filter lever. 27 A Do not operate a diesel engine when engine oil is overfilled. This can effect the air intake system which could result in engine damage or malfunction. C Checking oil level and adding engine oil 1. Check the engine oil level before starting or more than 5 minutes after stopping the engine. 2.
ENGLISH 28 PERIODIC SERVICE A When using oil of different brands from the previous one, be sure to drain all the previous oil before adding the new engine oil. C Changing Engine Oil CAUTION To avoid personal injury: A Be sure to stop the engine before draining engine oil. A When draining engine oil, place a suitable container underneath the engine and dispose of it according to local regulations. A DO NOT drain oil from a hot engine. Allow engine to cool down sufficiently to avoid being burned.
PERIODIC SERVICE 29 ENGLISH B Air Cleaner CAUTION To avoid personal injury: A Be sure to stop the engine before cleaning air filter element. A Make sure hooking clip is tight enough. If it is loose, dust and dirt may be sucked into the engine, causing excessive wear or premature engine failure and need for engine repair. C Cleaning Secondary Air Filter Element Since the air cleaner employed on this engine is a dry type, never apply oil to it. 1.
ENGLISH 30 PERIODIC SERVICE B Radiator A If the dust cup is mounted incorrectly, dust or dirt will not collect in the cup and allow the dust to come into direct contact with the element and thus require the element be replaced prematurely. Make it a rule to check the coolant level before every operation.
2. If the radiator is provided with a reserve tank, check the coolant level of the reserve tank. When it is between the "FULL" and "LOW" marks, the coolant will usually last for one day’s work. 31 C Changing coolant 1. To drain coolant, always remove both drain plugs and simultaneously open the radiator cap as well. With the radiator cap kept closed, the coolant will not drain completely. Dispose of used coolant properly. 2. Remove the overflow pipe of the radiator pressure cap to drain the reserve tank.
ENGLISH 32 PERIODIC SERVICE C Checking radiator hoses and clamps C Cleaning radiator core (outside) If dust is between the fin and tube, wash it away with running water. CAUTION To avoid personal injury: A Be sure to check radiator hoses and hose clamps periodically. If radiator hoses are damaged or coolant leaks out, overheating can occur. Check to see if radiator hoses are properly fixed every 200 hours of operation or 6 months, whichever comes first. 1.
3. Mixing the LLC Premix 50% LLC with 50% clean soft water. When mixing, stir it up well, and then fill into the radiator. 4. The procedure for the mixing of water and antifreeze differs according to the make of the antifreeze. Refer to SAE J1034 standard, more specifically also to SAE J814c.
