Group 20 General instructions Safety information This workshop manual contains technical data, descriptions and repair instructions for the Volvo Penta products or product versions noted in the table of contents. Check that you have the correct Workshop Ma- nual for your engine. Check that the warning or information labels on the product are always clearly visible. Replace labels which have been damaged or painted over. Never start the engine without the air cleaner fil- ter fitted. The rotating compressor turbine in the turbocharger can cause severe injury. Foreign objects entering the intake ducts can also cause mechanical damage. Never use start spray or similar products to aid starting. They may cause an explosion in the inlet manifold. Danger of personal injury. Only start the engine in a well- ventilated area. When operated in a confined space, exhaust fu- mes and crankcase gases must be ventilated from the engine bay or workshop area. Avoid opening the coolant filler cap when the engine is hot. Steam or hot coolant can spray out and the system pressure will be lost. When needed, open the filler cap slowly and release the pressure in the system. Be extremely care- ful if a tap, plug or coolant hose has to be removed from a hot engine. It is difficult to anticipate in which direction steam or hot coolant can spray out. Hot oil can cause burns. Avoid getting hot oil on the skin. Ensure that the lubrication system is not under pressure before carrying out any work on it. Never start or operate the engine with the oil filler cap removed, otherwise oil could be ejected. Important In this book and on the product you will find the following special warning symbols. WARNING! Possible danger of personal injury, extensive damage to property or serious mechanical malfunction if the instructions are not follo- wed. IMPORTANT! Used to draw your attention to so- mething that can cause damage or malfunctions on a product or damage to property. NOTE: Is used to call attention to important information, to facilitate work processes or operations. To give you a perspective of the risks which always need to be observed and precautions which always have to be taken, we have noted them below. Immobilize the engine by turning off the power with the main switch(es) and locking it (them) in the off position before starting service work. Fix a warning notice at the engine control point. All service work should normally be done on a stationary engine. Some work however, such as adjustments, needs the engine running. Ap- proaching an engine which is operating is a safety hazard. Remember that loose clothing or long hair can fasten in rotating parts and cause serious personal injury. If work is done adjacent to a running engine, a careless movement or a dropped tool can lead, in the worst case, to personal injury. Take care to avoid contact with hot surfaces (exhaust pipes, Turbocharger (TC), air intake pipe, starter heater etc.) and hot liquids in lines and hoses on an engine which is running or which has just been stopped. Reinstall all protective parts removed during service operations before starting the engine. Read the available safety information, “General information” and “Repair instructions” in the workshop manual before you start to do any service work.

General instructions Group 20 Stop the engine before carrying out operations on the engine cooling system. Always use protective glasses or goggles when carrying out work where there is a risk of splint- ers, grinding sparks, acid splashes or where other chemicals are used. Your eyes are extremely sensitive, injury could cause blindness! Avoid getting oil on the skin! Repeated exposure to oil or exposure over a long period can result in the skin becoming dry. Irritation, dryness, ec- zema and other skin problems can then occur. Used oil is more dangerous than fresh oil from a health aspect. Use protective gloves and avoid oil soaked clothes and shop rags. Wash regular- ly, especially before eating. There are special skin creams which counteract drying out of the skin and make it easier to clean off dirt after work is completed. Most chemicals intended for the product (e.g. engine and transmission oils, glycol, gasoline and diesel oil) or chemicals for workshop use (e.g. degreasers, paints and solvents) are hazardous. Read the instructions on the product package carefully! Always follow the safety precautions for the product (for example use of breathing mask, eye protection, gloves etc.). Make sure that other personnel are not unkno- wingly exposed to hazardous chemicals, for example via the air. Ensure good ventilation in the work place. Follow the instructions provided when disposing of used or leftover chemicals. Exercise extreme care when leak detecting on the fuel system and testing the fuel injector nozzles. Use eye protection. The jet from a fuel injector is under very high pressure, and has considerable penetration ability; fuel can force its way deep into body tissues and cause serious damage. Danger of blood poisoning (septi- cemia). WARNING! The injector pipes must under no circumstances be bent or reshaped. Damaged pipes must be replaced. All fuels, and many chemicals, are flammable. Do not allow naked flame or sparks in the vicini- ty. Certain thinner products and hydrogen from batteries are easily ignitable and are explosive when mixed with air in the right proportions. No Smoking! Ensure that the work area is well ventilated and take the necessary safety precautions before starting welding or grinding work. Al- ways ensure that there are fire extinguishers at hand when work is being carried out. Make sure that oil and fuel soaked rags, and used fuel and oil filters are stored in a safe place. Rags soaked in oil can spontaneously ignite under certain circumstances. Used fuel and oil filters are polluting waste and must be handed to an approved waste management facility for de- struction, together with used lubrication oil, con- taminated fuel, paint residue, solvents, degreasers and wash residue. Never expose a battery to naked flame or electrical sparks. Never smoke close to the batteries. The batteries give off hydrogen gas during charging which when mixed with air can form an explosive gas - oxyhydrogen. This gas is easily ignited and highly explosive. A spark, which can be formed if the batteries are wrongly connected, is enough to make a battery explode and cause damage. Do not shift the connections when attempting to start the engine (spark risk) and do not lean over any of the batteries. Always ensure that the Plus (positive) and Mi- nus (negative) battery cables are correctly installed on the corresponding terminal posts on the batteries. Incorrect installation can result in serious damage to the electrical equipment. Re- fer to the wiring diagram. Always use protective goggles when charging and handling the batteries. Battery electrolyte contains sulfuric acid which is highly corrosive. Should the battery electrolyte come into contact with unprotected skin wash off immediately using plenty of water and soap. If you get battery acid in your eyes, flush at once with a ge- nerous amount of water, and get medical assis- tance at once. Stop the engine and turn off the power at the main switch(es) before carrying out work on the electrical system.

Allmänna anvisningar 4 Grupp 20 The clutch must be adjusted with the engine stationary. Use the lifting eyes fitted on the engine when lifting the drive unit. Always check that the lifting equipment used is in good condition and has the load capacity to lift the engine (engine weight including gearbox, if fitted, and any extra equipment installed). Use an adjustable lifting beam, or lifting beam specifically for the engine, to raise the engine to ensure safe handling and to avoid damaging engine parts installed on the top of the engine. All chains and cables should run parallel to each other and as perpendicular as possible in rela- tion to the top of the engine. If other equipment connected to the engine has altered its center of gravity, special lifting devises may be needed to obtain the correct balan- ce and safe handling. Never carry out work on an engine suspended on a hoist. Never work alone when heavy components are to be dismantled, even when safe lifting devises such as lockable blocks & tackle are used. When using a lifting device two people are usu- ally required to do the work, one to take care of the lifting device and another to ensure that components are lifted clear and not damaged during the lifting operations. Always make sure that there is enough space for disassembly where you are working, with no risk for personal or material damage. WARNING! The components in the electrical system and in the fuel system on Volvo Penta products are designed and manufactured to mi- nimize the risk of fire and explosion. The engine must not be run in areas where there are explosive materials. Always use fuels recommended by Volvo Pen- ta. Refer to the Instruction Book. Use of fuels that are of a lower quality can damage the engine. On a diesel engine poor quality fuel can cause the control rod to seize and the engine to overrev with resulting risk of damage to the engine and personal injury. Poor fuel quality can also lead to higher maintenance costs. Remember the following when washing with a high pressure washer: Never aim the water jet at seals, rubber hoses or electrical components. Never use a high pressure washer for engine cleaning. The injectors can leak fuel when the engine is stationary, if the tank is higher than the engine and the fuel pressure is positive.

Group 20 General information Certified engines The manufacturer certifies that both new engines and those in use, which are certified for national or regio- nal legislation, comply with the environmental requirements. The following requirements for service and spare parts must be complied with, for Volvo Penta as a manufacturer to be responsible for ensuring that engines in use comply with the stipulated environmental requirements: • Maintenance and service intervals recommended by Volvo Penta must be complied with. • Only Volvo Penta Original Spare Parts intended for the certified engine version may be used. • Service related to injection pumps, pump settings and injectors must always be done by an authori- zed Volvo Penta workshop. • The engine must not be converted or modified in any way, except for the accessories and service kits which Volvo Penta has approved for the engine. • Installation changes to the exhaust pipe and the engine bay air inlet ducts (ventilation ducts) must not be done without further discussion, since this could affect exhaust emissions. • No tamper-seals may be broken by unauthorized personnel. The general advice in the instruction book about ope- ration, care and maintenance, applies. IMPORTANT! When spare parts are needed, use only Volvo Penta Original Spares. The use of non-original spare parts means that AB Volvo Penta can no longer be responsible for guaranteeing that the engine complies with the certified version. Any damage, injury and/or costs which arise due to the use of non-original Volvo Penta spares for the product in question will not be compensated by Volvo Penta.
