Safety information

IntroductionThe workshop manual contains technical data, de-scriptions and repair instructions for products or prod-uct versions noted in the table of contents, suppliedby Volvo Penta. Make sure you use the correct work-shop literature.

Read the available safety information, “General infor-mation” and “Repair instructions” in the workshopmanual before you start to do any service work.

Important

The following special warning signs are found in theworkshop manual and on the product.

WARNING! Warns for the risk of personal inju-ry, major damage to product or property, or se-rious malfunctions if the instruction is ignored.

IMPORTANT! Is used to call attention to thingswhich could cause damage or malfunctions toproduct or property.

NOTE! Is used to call attention to important informa-tion, to facilitate work processes or operation.

To give you a perspective on the risks which alwaysneed to be observed and precautions which alwayshave to be taken, we have noted them below.

Make it impossible to start the engine by cuttingsystem current with the main switch(es) andlock it (them) in the off position before startingservice work. Fix a warning sign by the helms-man’s seat.

All service work should normally be done on astationary engine. Some work, such as adjust-ments, need the engine to be running, however.Going close to a running engine is a safety risk.Remember that loose clothes, long hair etc. cancatch on rotating components and cause se-vere injury.

If work is done adjacent to a running engine, acareless movement or a dropped tool can leadto personal injury in the worst case. Be carefulwith hot surfaces (exhaust pipes, turbos, chargeair pipes, starting heaters etc.) and hot fluids inpipes and hoses on an engine which is runningor which has just stopped. Re-install all guardswhich have been removed during service work,before re-starting the engine.

Make sure that the warning or information la-bels on the product are always clearly visible.Replace labels which have been damaged orpainted over.

Never start an engine without the air filter inplace. The rotating compressor turbine in theturbocharger can cause severe injury. Foreignbodies in the inlet pipe can also cause severemechanical damage.

Never use start spray or similar products as astarting aid. Explosions could occur in the inletmanifold. Danger of personal injury.

Avoid opening the coolant filling cap when theengine is hot. Steam or hot coolant can sprayout at the same time as the pressure which hasbuilt up is lost. Open the filler cap slowly, andrelease the pressure in the cooling system if thefilling cap or tap has to be opened, or if a plugor coolant hose has to be removed when theengine is hot. Steam or hot coolant can streamout in an unexpected direction.

Hot oil can cause burns. Avoid skin contact withhot oil. Make sure that the oil system is de-pres-surised before doing any work on it. Never startor run the engine with the oil filler cap removed,because of the risk of oil spillage.

Stop the engine and close the sea cocks beforedoing any work on the cooling system.

Only start the engine in a well-ventilated area.When operated in a confined space, exhaustfumes and crankcase gases must be ventilatedfrom the engine bay or workshop area.

Always use goggles when doing any workwhere there is any risk of splinters, grindingsparks, acid splash or other chemicals. Youreyes are extremely sensitive, injury could causeblindness!

Safety information

Avoid skin contact with oil! Long-term or repeat-ed skin contact with oil can make your skin dryout. The consequence is irritation, dry skin, ec-zema and other skin disorders. Used oil is morehazardous to health than new oil. Use protec-tive gloves and avoid oil-soaked clothes andrags. Wash regularly, especially before meals.Use special skin cream to avoid drying and fa-cilitate skin cleaning.

Most chemicals intended for the product (e.g.engine and transmission oils, glycol, petrol(gasoline) and diesel oil) or chemicals for work-shop use (e.g. degreasers, paints and solvents)are hazardous. Read the instruction on thepackages carefully! Always observe the safetyadvice (e.g. use of breathing protection, gog-gles, gloves etc.). Make sure that other person-nel are not inadvertently exposed to hazardoussubstances, such as via the air they breathe.Ensure good ventilation. Handle used and sur-plus chemicals in the prescribed manner.

Be very careful when searching for leaks in thefuel system and testing fuel injectors. Use gog-gles. The jet which comes from a fuel injectorhas very high pressure and considerable pene-tration ability. Fuel can force its way deep intobody tissue and cause severe injury. Risk ofblood poisoning (septicaemia).

All fuels, and many chemicals, are flammable.Make sure that open flames or sparks can notset them alight. Petrol (gasoline), some thinnersand hydrogen gas from batteries are extremelyflammable and explosive when mixed with air inthe correct ratio. Do not smoke! Provide goodventilation and take the necessary precautionsbefore you start welding or grinding in the vicini-ty. Always have a fire extinguisher easily avail-able near the workplace.

Make sure that oil and fuel soaked rags, andused fuel and oil filters are stored in a safeplace. Oil soaked rags can self-ignite in certaincircumstances. Used fuel and oil filters are pol-luting waste and must be handed to an ap-proved waste management facility for destruc-tion, together with used lubrication oil, contami-nated fuel, paint residue, solvents, degreasersand wash residue.

Batteries must never be exposed to openflames or electric sparks. Do not smoke close tothe batteries. The batteries generate hydrogengas when charged, which forms an explosivegas when mixed with air. This gas is very flam-mable and highly explosive. A spark, which can

be formed if the batteries are wrongly connect-ed, is enough to make a battery explode andcause damage. Do not move the connectionwhen you attempt to start the engine (risk ofarcing), and do not stand and lean over one ofthe batteries.

Never mix up the battery positive and negativepoles when the batteries are installed. If the bat-teries are wrongly connected, this can causesevere damage to the electrical equipment.Please check the wiring diagram!

Always use goggles when charging and han-dling batteries. Battery electrolyte contains high-ly corrosive sulphuric acid. If this comes intocontact with your skin, wash at once with soapand a lot of water. If you get battery acid in youreyes, flush at once with a generous amount ofwater, and get medical assistance at once.

Stop the engine and cut the system current withthe main switch(es) before doing any work onthe electrical system.

The clutch must be adjusted with the engineshut off.

The existing lugs on the engine/reverse gearshould be used for lifting. Always check that thelifting devices are in good condition and thatthey have the correct capacity for the lift (theweight of the engine plus the reverse gear andextra equipment if installed).The engine should be lifted with a customisedor adjustable lifting boom for safe handling andto avoid damaging components on top of theengine. All chains or cables should be parallelto each other and should be as square as pos-sible to the top of the engine.If other equipment connected to the engine hasaltered its centre of gravity, special lifting devic-es may be needed to obtain the correct balanceand safe handling.Never do any work on an engine which justhangs from a lifting device.

Never work alone when heavy components areto be dismantled, even when safe lifting devicessuch as lockable blocks & tackle are used.Even when lifting devices are used, two peopleare needed in most cases. One who operatesthe lifting device and other who makes sure thatcomponents move freely and are not damagedduring lifting.When you work aboard a boat, always makesure that there is enough space for disassemblywhere you are working, with no risk for personalor material damage.

Safety information

Components in the electrical and fuel systemson Volvo Penta products have been designedto minimise the risks of explosion and fire. Theengine must not be operated in environmentswith adjacent explosive media.

Remember the following when washing with ahigh pressure washer: Never aim the water jetat seals, rubber hoses or electrical components.Never use a high pressure washer for enginecleaning.

Only use the fuels recommended by Volvo Pen-ta. Please refer to the instruction book. The useof fuel of inferior quality can damage the en-gine. In a diesel engine, poor fuel can cause theregulation rod to bind and the engine will over-rev, entailing a strong risk of personal injury andmachinery damage. Poor fuel can also lead tohigher maintenance costs.

General information

About the workshop manualThis workshop contains the wiring diagrams for thestandard versions of engines TAMD61A, TAMD62A,TAMD63L-A, TAMD63P-A, TAMD71A, TAMD71B,TAMD72A, TAMD72P-A, TAMD72WJ-A,TAMD73P-A, TAMD73WJ-A, TAMD74A-A,TAMD74A-B, TAMD74C-A, TAMD74L-A,TAMD74P-A, TAMD74C-B, TAMD74L-B,TAMD74P-B.

The engine designation and number are noted on thenumber plate. The engine designation and numbermust always be given in all correspondence about anengine.

The workshop manual has been primarily preparedfor Volvo Penta service workshops and their qualifiedpersonnel. This assumes that people who use theManual have basic knowledge of marine drive sys-tems and can do the tasks of a mechanical or electri-cal nature associated with the trade. Volvo Pentaconstantly improves its products, so we reserve theright to make modifications without prior notification.All information in this manual is based on productdata which was available up to the date on which themanual was printed. Any material changes introducedinto the product or service methods after this date arenotified by means of Service Bulletins.

Spare partsSpare parts for electrical and fuel systems are subjectto various national safety requirements. Volvo PentaOriginal Spares comply with these requirements. Nodamage whatever, occasioned by use of non-originalVolvo Penta spares for the product, will be compen-sated by the warranty offered by Volvo Penta.

Certified enginesWhen service or repairs are done to an emissioncertified engine, which is used in an area whereexhaust emissions are regulated by law, it is im-portant to be aware of the following:

Certification means that an engine type has beenchecked and approved by the relevant authority. Theengine manufacturer guarantees that all enginesmade of the same type are equivalent to the certifiedengine.

This put special demands on service and repairwork, as follows:

l Maintenance and service intervals recommendedby Volvo Penta must be complied with.

l Only Volvo Penta original spares may be used.

l Service to injection pumps, pump settings and in-jectors must always be done by an authorisedVolvo Penta workshop.

l The engine must not be converted or modified,except for the accessories and service kits whichVolvo Penta has approved for the engine.

l Installation changes to the exhaust pipe and en-gine air inlet ducts must not be done.

l No seals may be broken by unauthorised person-nel.

The general advice in the instruction book about op-eration, care and maintenance applies.

IMPORTANT! Delayed or inferior care/mainte-nance, and the use of non-original spares,mean that AB Volvo Penta can no longer be re-sponsible for guaranteeing that the engine com-plies with the certified version.

Damage, injury and/or costs which arise fromthis will not be compensated by Volvo Penta.
