  • Page 3 Operating Instructions − MAN Industrial Gas Engines...
  • Page 5: Preface

    Comply in full with instructions relating to operation, prevention of accidents and environmental protection. MAN Gas Engines are developed and manufactured in line with the latest state of the art. However, trouble-free operation and high performance can only be achieved if the speci- fied maintenance intervals are observed and only approved fuels, lubricants and coolants are used.

  • Page 10: Safety Regulations

    D Before putting the engine into operation for the first time, read the oper- ating instructions carefully and familiarize yourself with the “critical” points. If you are unsure, ask your MAN representative. D For reasons of safety we recommend you attach a notice to the door of...
  • Page 11 Ë Ë D Exhaust gases are toxic. Comply with the regulations for the installation of MAN gas engines intended for operation in closed spaces. Ensure that there is adequate ventilation and air extraction. D Keep vicinity of engine, ladders and stairways free of oil and grease.
  • Page 12 If faults occur, find the cause immediately and have it eliminated in order to prevent more serious damage. If necessary inform MAN’s customer service. Use only genuine MAN spare parts. MAN does not accept any responsibility for damage resulting from the installation of parts from other companies or for installation by unau- thorised persons.
  • Page 13 Safety regulations 3. Regulations designed to prevent pollution Engine oil and filter elements / cartridges D Take old oil only to an old oil collection point. D Take strict precautions to ensure that no oil gets into the drains or the ground. Caution: The drinking water supply could be contaminated.
  • Page 14 Safety regulations 4. Notes on safety in handling used engine oil * Prolonged or repeated contact between the skin and any kind of engine oil decreases the skin. Drying, irritation or inflammation of the skin may therefore occur. Used engine oil also contains dangerous substances which have caused skin cancer in animal experi- ments.
  • Page 15 Safety regulations 5. Safety instructions for dealing with gaseous fuels Gaseous fuels consist mainly of methane, propane and butane and of traces of higher hydrocarbons and of inert components such as carbon dioxide and ni- trogen. D Smoking and playing with fire is prohibited. D Leakage in the gas supply system causes a risk of explosion and must be immediately eliminated.

  • Page 20: First Commissioning

    When putting a new or overhauled engine into operation for the first time pay attention to the “Installation Instructions for MAN Industrial Gas Engines” without fail. It is recommended that new or overhauled engines should not be operated at a load higher than about 75% maximum load during the first 5 hours of operation.

  • Page 24: Commissioning

    Commissioning and operation Commissioning Before daily starting the engine, check fuel level, coolant level and engine oil level and replenish, if necessary. Caution: Use only approved fuels, lubricants etc. (see brochure “Fuels, lubricants etc.”). Otherwise the manufacturer’s warranty will become null and void. Checking oil level Check engine oil level only approx.
  • Page 25: Starting

    Before starting make sure that no-one is in the engine’s danger area. IC 900 ignition system is used for MAN’s E 2842 LE 302 / E 2842 LE312 gas engine. The electronic ignition system is a high-voltage capacitor ignition system with microprocessor control based on crankshaft revolutions.
  • Page 26: Operation Monitoring System

    Caution: If faults occur, find their cause immediately and have them eliminated in order to prevent more serious damage! If necessary consult MAN’s customer service. The oil pressure and coolant temperature are constantly monitored during operation. The engine is automatically immobilised if the values fall short of or exceed the limits.
  • Page 27: Gas System

    Any deviations from this will impair the power output, the engine efficiency and the exhaust gas emissions. The requirements relating to gas quality can be found in the “MAN Data Sheet − Mini- mum Gas Quality Requirement for MAN Gas Engines”.
  • Page 28: Maintenance And Care

    Maintenance and care Lubrication system Ensure outmost cleanliness when handling fuels, lubricants and coolants. Caution: Use only approved fuels, lubricants etc. (see brochure “Fuels, lubricants etc.”). Otherwise the manufacturer’s warranty will become null and void. Engine oil change Danger: The oil is hot- risk of scalding. Do not touch the oil drain plug with bare fingers.
  • Page 29 Maintenance and care Refilling with oil Caution: Do not add so much engine oil that the oil level rises above the max. marking on the dipstick. Overfilling will result in damage to the engine. Refill with fresh engine oil at the oil filler neck (arrow).1.
  • Page 30 Maintenance and care Changing oil filter However, oil filter cartridges must be changed at every oil change. Caution: Used oil and oil filters are classed as dangerous waste. Observe safety regulations to prevent dam- age to the environment. Renewal of filter cartridges Danger: Oil filter can and oil filter are filled with hot oil.
  • Page 31: Cooling System

    Danger: Draining hot coolant involves a risk of scalding. For a suitable protective agent see “Approved fuels, coolants and lubricants in accordance with MAN 324 and 248”. Draining the cooling system Caution: Drain coolant into a suitable con- tainer and dispose of it in accord- ance with regulations.
  • Page 32 Maintenance and care Fill / bleed the cooling system (only when engine has cooled down) Fill the cooling system of the engine with a mixture of drinkable tap water and anti-freeze agent on ethylene glycole basis or anti-corrosion agent. Caution: Use only approved fuels, lubricants etc.
