KD1800/KD6 GENERAL INFORMATION KD1800/KD6 FAMILIARIZATION Generator Housed within the KD1800/KD6 generator package is a Marathon Model 332, 6,000 watt (6-KW) generator. This generator can provide up to 50 amps of current. In addition two voltage output receptacles have been provided on the generator's control box. One receptacle has an output of 120/250 VAC and the other is a 120 VAC, GFCI protected receptacle. The Marathon Model 332 generator should only be operated at a frequency of 60 hertz. The speed should be 1,850 rpm's (no load) and 1,800 rpm's (full load). A single capacitor is used to regulate the voltage to within 5% of the rated load. The engine-generator set must be installed in a protected environment, with a minimal exposure to fumes, moisture, dust and dirt. NOTE When operating the generator, remember the outside air temperature must not exceed 40 C (104 F). Remember the following when using the generator: DO NOT obstruct the generator's intake and outlet passages. ALWAYS provide sufficient air circulation around the generator to remove engine heat and to provide ample generator cooling. HOT AIR from the radiator must not enter into the generator. Use extreme caution when handling capacitors. A potential shock condition exist even when the engine has been shut-off. See maintenance section of this manual for the proper handling of capacitors. For operation at high altitudes, ratings must be derated 2% for each 1000 feet above sea level. Frame temperatures above 60 C (104 F) are too high, indicating a temperature rise in the copper windings of 105 C (122 F) or more. After running the generator for 30 minutes at full load check the temperature rise. If the temperature is excessive, examine the generator for the following: A. Obstructed air-flow B.

KD1800/KD6 INSTALLATION Outdoor Installation Install the generator in a location where it will not be exposed to rain or sunshine. Make sure that the welder/generator is on secure level ground so that it cannot slide or shift around. Also install the generator in a manner so that the exhaust will not be discharged in the direction of nearby homes. The installation site must be relatively free from moisture and dust. All electrical equipment should be protected from excessive moisture. Failure to do will result in deterioration of the insulation and will result in short circuits and grounding. Foreign materials such as dust, sand, lint and abrasive materials have a tendency to cause excessive wear, not only to the engine parts, but also to the alternator parts. Indoor Installation Exhaust gases from diesel engines are extremely poisonous. Whenever an engine is installed indoors the exhaust fumes must be vented to the outside. The engine should be installed at least two feet from any outside wall. Using an exhaust pipe which is too long or too small can cause excessive back pressure which will cause the engine to heat excessively and possibly burn the valves. Eliminate the danger of deadly carbon monoxide gas. Remember that exhaust fumes from any gasoline engine are very poisonous if discharged in a closed room, but harmless if allowed to mix with the outside air. If the generator is installed indoors, you must make provisions for venting the engine exhaust to the outside of the building. CAUTION : Pay close attention to ventilation when operating the generator inside tunnels and caves. The engine exhaust contains noxious elements. PAGE 18 KD1800/KD6 A.C. GENERATOR PARTS & OPERATION MANUAL REV. #1 (06/16/05)

KD1800/KD6 PRE-SETUP (GENERATOR) General Inspection Prior to Operation The KD1800/KD6 utilizes a generator that has been thoroughly inspected and accepted prior to shipment from the factory. However, be sure to check for damaged parts or components, or loose nuts and bolts, which could have occurred in transit. Generator Grounding To guard against electrical shock and possible damage to the equipment, it is important to provide a good EARTH ground. Article 250 (Grounding) of the National Electrical Code (NEC) provides guide lines for proper grounding and specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical. If a building is not accessible, then the use of a ground rod is sufficient. NOTE Check local city codes for proper grounding requirements. NEC articles 250-91a and 250-95 sets the following grounding requirements: 1. Use one of the following wire types to connect the generator to earth ground. a. Copper - 10 AWG (5.3 mm 2 ) or larger. b. Aluminum - 8 AWG (8.4 mm 2 ) or larger. 2. The ground terminal on the generator should always be used to connect the generator to a suitable ground. The ground ring on the generator (Figure 3) should be able to accommodate #8 size copper or aluminum wire. 3. Crimp the ground wire to the ground lug on the generator. Connect the other end of the ground wire to a suitable building ground or ground rod. 4. NEC article 250-83c specifies that the earth ground rod should be buried a minimum of 8 ft. into the ground. NOTE When connecting the generator to any buildings electrical system ALWAYS consult with a licensed electrician. Figure 3. Generator Grounding Configuration KD1800/KD6 A.C. GENERATOR PARTS & OPERATION MANUAL REV. #1 (06/16/05) PAGE 19

Circuit Breakers To protect the generator from an overload, a 2-pole, 30 amp, main circuit breaker is provided. In addition a single pole, 15 amp breaker is provided for the G.F.C.I. receptacle. Make sure to switch both circuit breakers to the "OFF" position prior to starting the engine. KD1800/KD6 PRE-SETUP (GENERATOR) Extension Cable When electric power is to be provided to various tools or loads at some distance from the generator, extension cords are normally used. Cables should be sized to allow for distance in length and amperage so that the voltage drop between the generator and point of use (load) is held to a minimum. Use the cable selection chart (Table 3 ) as a guide for selecting proper cable size. Table 3. Extension Cable Selection (60 Hz, Single Phase Operation) Current in Amperes Load At 120 Volts In Watts At 240 Volts Maximum Allowable Cable Length # 10 Wire # 12 Wire # 14 Wire #16 Wire 2.5 300 600 1000 ft. 600 ft. 375 ft. 250 ft. 5 600 1200 500 ft. 300 ft. 200 ft. 125 ft. 7.5 900 1800 350 ft. 200 ft. 125 ft. 100 ft. 10 1200 2400 250 ft. 150 ft. 100 ft. 15 1800 3600 150 ft. 100 ft. 65 ft. 20 2400 4800 125 ft. 75 ft. 50 ft. 30 3600 7200 75 ft. 50 ft. 35 ft.

KD1800/KD6 PRE-SETUP (ENGINE) Lubrication Oil (Engine) Fill the engine crankcase with lubricating oil through the filler hole, but do not overfill. Make sure the generator is level. With the dipstick inserted all the way into its holder. Verify that the oil level is maintained between the two notches (Figure 4) on the dipstick. See Table 4 for proper selection of engine oil. Fuel Fill the fuel tank with No. 2 diesel fuel. DO NOT fill the tank beyond capacity. Use a strainer when pouring the fuel into the tank. This will prevent dirt and debris from entering the fuel system. Pay attention to the fuel tank capacity when replenishing fuel. Refer to the fuel tank capacity listed on page 13, Engine Specification Table 2. The fuel tank cap must be closed tightly after filling. Handle fuel in a safety container. If the container does not have a spout, use a funnel. CAUTION : Figure 4. Engine Oil Dipstick NEVER fill the fuel tank while the engine is running or in the dark. Diesel fuel spillage on a hot engine can cause a fire or explosion. If diesel fuel spillage occurs, wipe up the spilled gasoline completely to prevent fire hazards. Coolant Check coolant level as described in the maintenance section of this manual. Use distilled water mixed with coolant. If hard water or water with many impurities is used, the inside of the engine and radiator may become coated with deposits and cooling efficiency will be reduced. Table 4.

GENERATOR PARTS & OPERATION MANUAL REV. #1 (06/16/05) PAGE 23

KD1800/KD6 LOAD APPLICATION Single Phase Load Always be sure to check the nameplate on the generator and equipment to insure the wattage, amperage and frequency requirements are satisfactorily supplied by the generator for operating the equipment. Generally, the wattage listed on the nameplate of the equipment is its rated output. Equipment may require 130 150% more wattage than the rating on the nameplate, as the wattage is influenced by the efficiency, power factor and starting system of the equipment. NOTE If wattage is not given on the equipment's name plate, approximate wattage may be determined by multiplying nameplate voltage by the nameplate amperage. WATTS = VOLTAGE x AMPERAGE The power factor of this generator is 1.0. See Table 5 below when connecting loads. Table 5. Power Factor By Load Type Of Load Power Factor Single-phase induction motors 0.4-0.75 Electric lamps heaters, incandescent 1.0 Fluorescent lamps, mecury lamps 0.4-0. 9 Electronic devices, communication equipment 1.0 When connecting ordinary power tools, a capacity of up to the generating set s rated output (kw) multiplied by 0.8 can be used. When connecting a resistance load such as an incandescent lamp or electric heater, a capacity of up to the generating set s rated output (kw) can be used. When connecting a fluorescent or mercury lamp, a capacity of up to the generating set s rated output (kw) multiplied by 0.6 can be used. When connecting an electric drill or other power tools, pay close attention to the required starting current capacity. CAUTION: Motors and motor-driven equipment draw much greater current for starting than during operation. An inadequate size connecting cable which cannot carry the required load can cause a voltage drop which can burn out the appliance or tool and overheat the cable. CAUTION: Before connecting this generator to any building s electrical system, a licensed electrician must install an isolation (transfer) switch. Serious injury or death may result without this transfer switch. PAGE 24 KD1800/KD6 A.C. GENERATOR PARTS & OPERATION MANUAL REV. #1 (06/16/05)

KD1800/KD6 ENGINE OPERATING INSTRUCTIONS WARNING: Before Starting 1. Be sure to disconnect the electrical load and switch the main circuit breaker to the "OFF" position prior to starting the engine. Also switch the GFCI circuit breaker to the "OFF" position. 2. NEVER start the engine with the main or GFCI circuit breakers in the ON position. 3. Check the lubricating oil level prior to starting the engine. Make sure the generator is level. The oil level must be maintained between two notches on the dipstick. 4. When there is not enough lubricating oil, fill the crankcase with high grade motor oil. Use a high quality detergent oil classified CC or higher (See Table 4 on page 21). 5. Check the coolant level in the radiator and subtank. Replenish with anti-freeze as necessary. ALWAYS maintain the coolant level between the FULL and LOW markings on the coolant container. Be sure that the radiator cap is fastened securely. CAUTION: The engine's exhaust contains harmful emissions. ALWAYS ventilate the exhaust when operating inside tunnels, excavations or buildings. Direct exhaust away from nearby personnel. Check the fuel source for low fuel level. When fuel is low, fill the fuel tank with clean fresh automotive No. 2 diesel fuel. If diesel fuel spillage occurs, completely wipe up the spilled diesel fuel. Engine Starting Procedure (Diesel) 1. ALWAYS operate the generator with the doors in the closed position. Operation with the doors open may cause insufficient cooling to the unit, and damage may result. 2. Insert the key into the ignition switch and turn it counterclockwise to the "PRE-HEAT" position. 3. When the "PRE-HEAT" lamp goes off, turn the key to clockwise to the START position. As soon as the engine starts, release the key. 4. If the engine does not start within 10 seconds after the key is turned to the START position, wait for about 30 seconds and repeat the procedure as described in steps 1 through 4.

KD1800/KD6 MAINTENANCE (ENGINE) General Inspection At least daily or prior to each use, the generator should be cleaned and inspected for deficiencies. Check for loose, missing or damaged nuts, bolts or other fasteners. Also check for fuel or oil leaks. Engine Side: For a more detail engine maintenance schedule refer to the KUBOTA Engine Shop and Operator's Manual. Air Cleaner Every 50 hours: The air cleaner employed on the KUBOTA engine Model D905EBG is a dry type, NEVER apply oil to it. If the generator will be operating in very dusty and dry grass conditions, a clogged air cleaner will result in high fuel consumption, loss of power and excessive carbon buildup in the combustion chamber. Service air cleaner daily. 1. Open the evacuator valve (Figure 6) once a week under ordinary conditions or daily in dusty conditions. This will eliminate large particles of dust and dirt within the air cleaner. Figure 6. Air Cleaner 2. Wipe the inside of the air cleaner with a damp cloth and remove all dust and debris that may have accumulated inside air cleaner body. 3. Avoid touching the element except when cleaning. 4. Use compressed air to clean air filter element. Blow compressed air from the inside while turning the element. ALWAYS keep the pressure of the compressed air below 99 psi. 5. If carbon or oil adheres to the element, soak the element in detergent for 15 minutes, then wash it several times in water, rinse with clean water and let dry. 6. After the element is fully dried, inspect the inside of the element with a light, and check for damage (refer to the instructions on the label attached to the element). 7. Replace the element once a year or every six cleanings. CAUTION: Make sure the wing nut for the air cleaner is tight enough. If is loose, dust and dirt may be sucked in, wearing down the cylinder liner and piston ring, and thereby resulting in poor power output. DO NOT over service the air cleaner element. Over servicing may cause dirt to enter the engine causing premature wear. Use the dust indicator as a guide on when to service the element. Oil Change Every 200 hours: Change the engine oil after the first 50 hours of operation and every 200 hours thereafter. ALWAYS 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 when checking the oil level. 1. Remove the oil dipstick from its holder, wipe it clean and reinstall it. 2. Remove the oil dipstick again from its holder, and check the oil level. 3. The oil level must be between the two notches on the dipstick as shown in Figure 7. Figure 7. Engine Oil Dipstick PAGE 26 KD1800/KD6 A.C. GENERATOR PARTS & OPERATION MANUAL REV. #1 (06/16/05)

KD1800/KD6 MAINTENANCE (ENGINE) 4. If the engine oil level is too low, remove the engine oil filler cap Figure 9, and fill to the correct operating level. Fuel Lines Every 50 hours: Check the fuel lines and associated clamp bands every 50 hours of operation. 1. If the rubber fuel lines and clamp bands become worn, replace them immediately. Replace all rubber fuel lines every two years. Replacing the Fuel Filter Every 400 hours: Replace the fuel filter (Figure 11) every 400 hours. CAUTION: Figure 9. Engine Oil Filler Hole Engine oil should be MIL-L2104C or have properties of API classification CD grades or higher. When changing the engine oil, use a oil with a viscosity appropriate for the atmospheric temperature at the site. Use SAE-30 oil in the summer, SAE-20 in the winter, or all season SAE 10W-30 oil which offers stable viscosity at various ambient temperatures. See Table 4. When different type oil brands are used, be sure to drain all the previous oil before adding the new engine oil. Oil Cartridge Every 200 hours: Replace the engine oil filter cartridge (Figure 10) after every 200 hours of operation. Figure 11. Fuel Filter Fuel Addition When adding diesel fuel to the fuel tank, the grade may vary according to season and locations. Typically use No. 2 diesel fuel will filling the fuel tank. Always pour through a mesh filter, this will prevent sand and dirt from entering the fuel system. Removing Water (Condensation) from the Fuel Tank After prolonged use, water and other impurities accumulate in the bottom of the tank. Occasionally remove the drain cock and drain the contents. During cold weather, the more empty area inside the tank, the easier it is for water to accumulate. This can be reduced by always keeping the tank as full as possible. Figure 10. Oil Filter Cartridge 1. Remove the old oil filter cartridge with a filter wrench. 2. Apply a film of oil to the gasket for the new cartridge. 3. Screw the new cartridge in by hand. DO NOT use the filter wrench to tighten the new filter. 4. Run the engine for a few minutes, check for leaks. Check engine oil level, add oil if necessary. NOTE The fuel tank for this generator is contained within the trailer section of the Modular Light Tower (MLT). KD1800/KD6 A.C. GENERATOR PARTS & OPERATION MANUAL REV. #1 (06/16/05) PAGE 27

KD1800/KD6 MAINTENANCE (ENGINE) Air Removal If air enters the fuel 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 key switch to the START position for 15-30 seconds. Try again, if needed. This unit is equipped with an automatic air bleeding system. Radiator Check Daily: Coolant will last for one day's work if filled to the maximum level. CAUTION: 2. Check the coolant level in the reserve tank, (Figure 13), make sure it is filled to the "FULL" marking with coolant. The coolant will last for one days work if filled to the "FULL" mark. Replenish coolant as coolant approaches "LOW" marking on reserve tank. 3. DO NOT refill the reserve tank with coolant beyond the "FULL" marking. Figure 13. Reserve Tank NEVER remove the radiator cap while the coolant is hot! Let radiator cool before removing cap. Severe burns and bodily injury could result from removing the radiator cap when the radiator is hot. NEVER stop engine suddenly to add coolant, let engine idle for 3-5 minutes with no load. Then shut-down engine and let cool. Checking Coolant Level 1. Remove the radiator cap (Figure 12) only after the engine has completely cooled, and check to see that the coolant reaches the supply port. Adding Coolant/Anti-freeze Day-to-day addition of coolant or antifreeze is done via the reserve tank. See Table 6 for engine/radiator and reserve tank coolant capacities and Table 7 for coolant operating temperatures. Make sure that the coolant level in the reserve tank is always between the "FULL" and the "LOW" markings. Engine and Radiator Table 6. Coolant Capacity 3.1 Liters (0.82 Gal.)

KD1800/KD6 MAINTENANCE (ENGINE) Anti-freeze Recommendations Use rubber gloves when handling anti-freeze. When anti-freeze comes in contact with the skin or clothing, wash it off immediately. DO NOT mix different types of anti-freeze. Keep fire, children and animals away from anti-freeze. Check with local safety codes on the proper disposal techniques of anti-freeze. NOTE When the anti-freeze is mixed with water, the anti-freeze mixing ratio must be less than 50%. The battery is sufficiently charged if the specific gravity of the battery fluid is 1.28 (at 68 F). If the specific gravity should fall to 1.245 or lower, it indicates that the battery is dead and needs to be recharged or replaced. Check to see whether the battery cables are loose. Poor contact may result in poor starting or malfunctions, always keep the terminals firmly tightened. Coating the terminals with a thin film of grease will help to inhibit corrosion. The battery gradually deteriorates over time. The actual life span will vary according to operating conditions, but generally a battery two years or older should be replaced. 1. Make sure each electrolyte level (Figure 14) is to the bottom of the vent well. If necessary add distilled water in a well-ventilated area. Battery CAUTION: ALWAYS follow safety rules when handling the battery. NEVER charge the battery in a flammable environment. ALWAYS keep open sparks and flames away from the battery at all the times. NEVER let the battery's electrolyte contact your body or clothing. ALWAYS wear gloves when handling the battery. ALWAYS wear eye protection and rubber gloves when handling the battery. Remember the diluted sulfuric acid solution within the battery burns skin and eats holes in clothing. If any part of your body comes in contact with the sulfuric acid of the battery, immediately wash it off with running water and get medical attention. Figure 14. Battery Electrolyte Level Direction For Long Term Storage (Battery) 1. Remove the battery from the generator. Adjust the electrolyte to the correct level, and store in a dry and dark place. 2. Recharge battery once a month in summer, and every two months in winter. This unit is of negative ground. DO NOT connect in reverse. Always maintain battery fluid level between the specified marks. Battery life will be shortened, if the fluid level is not properly maintained. Add only distilled water when replenishment is necessary. KD1800/KD6 A.C. GENERATOR PARTS & OPERATION MANUAL REV. #1 (06/16/05) PAGE 29

KD1800/KD6 MAINTENANCE (GENERATOR) Generator Capacitor Regulation A single capacitor is used to regulate the voltage to within 5% of the rated load. ALWAYS USE EXTREME CAUTION when handling capacitors. The capacitor will still contain a high voltage even after the engine has been shut-down. ALWAYS discharge the capacitor before handling. Use a conductor or a screwdriver (Figure 15) with an insulated handle. Place screwdriver across both capacitor terminals while holding onto the handle. This will short out the voltage and discharge the capacitor. Flashing Rotor Procedure NOTE DO NOT run the generator during this procedure. 1. Disconnect all incoming power leads to the generator. 2. Connect the (+) lead of a 12 volt battery to the "R" connection (Figure 16). Figure 15. Discharging Capacitor Figure 16. Flashing The Rotor Configuration 3. Connect the (-) lead of the battery to the rotor shaft. Checking the Charge of the Capacitor 1. Use an "OHMMETER" to check the charge and discharge of the capacitor. Set the ohmmeter to the RX-1000 scale. 2. Place the ohmmeter leads on the capacitor terminals one at a time. A meter deflection should be seen (charging), followed by a slow return to infinity (discharging). 3. Reverse the ohmmeter leads and repeat the procedure. The results should be the same. Replace the capacitor if no meter deflection or continuity has been indicated by the ohmmeter. 4. Re-connect all incoming power leads to the generator 5. Start the generator as outlined in the "Operating Section" of this manual. 6. With a voltmeter check the no load voltage at the 120/ 240 output connector located on the control box. 7. The no load should be within 10% of the rated load. 8. If residual voltage is normal, the capacitor is defective and should be replaced. Diode Check 1. Check the diode individually by removing the (+) rotor lead stud connection (Figure 16). The diode is good if the resistance reading is approximately mid -scale on the lowest ohm scale. 2. Check for leakage in the diode by reversing the polarity. The diode is good if the resistance reading is infinite. 3. A faulty diode will give a resistance value of zero. PAGE 30 KD1800/KD6 A.C.
