! Immobilize the engine by turning off the powersupply to the engine at the main switch(switches) and lock it (them) in the off positionbefore starting work. Post a warning notice atthe main circuit breaker.
! Avoid opening the coolant filling cap when theengine is hot. Steam or hot coolant can sprayout and system pressure will be lost. Open thefiller cap slowly, and release the pressure in thecooling system if the filler cap or valve has to beopened, or if a plug or coolant hose has to beremoved when the engine is hot.
! As a rule, all service operations must be carriedout with the engine stopped. However, somework, such as adjustments, will require theengine to be running. Approaching an enginewhich is running is a safety risk. Bear in mindthat loose clothing or long hair can fasten inrotating parts and cause serious personalinjury.
! Hot oil can cause burns. Avoid skin contact withhot oil. Ensure that the lubrication system is notunder pressure before any work is begun.Never start or operate the engine with the oilfiller cap removed, because of the risk of oilejection.
! Be aware of hot surfaces (exhaust pipes,turbos, charge air pipes, starting heaters etc.)and hot fluids in pipes and hoses on an enginethat is running or has just stopped.If work is done adjacent to a running engine, acareless movement or a dropped tool may in theworst case lead to personal injury.
! Never start the engine without installing the airfilter. The rotating compressor turbine in theturbocharger can cause severe injury. Foreignobjects entering the intake ducts can also causemechanical damage. Install all protectivecovers before the engine is started.
! Ensure that the warning symbols or informationdecals on the product are always clearly visible.Replace decals which have been damaged orpainted over.
! Only start the engine in a well-ventilated space.When running in a confined space, exhaustfumes and crankcase gases must be led awayfrom the engine bay or workshop area.
! Avoid getting oil on your skin! Protracted orrepeated exposure to oil can cause skin tobecome dry. Irritation, dryness, eczema andother skin problems may then result. From ahealth standpoint, used oil is more dangerousthan new. Use protective gloves and avoid oil-soaked clothes and rags. Wash regularly,especially before eating. Use suitable barriercreams to counteract drying out of the skin andto aid dirt removal.
! The majority of chemicals e.g. engine andtransmission oils, glycol, gasoline, and dieseloil, together with chemicals for workshop usesuch as degreasing agents, paints andsolvents, are injurious to health. Carefully readthe instructions on the product packaging!Always follow a product's safety directions, e.g.use of protective mask, glasses, gloves etc.Ensure that other personnel are not exposed tosubstances that are injurious to health. Ensuregood ventilation. Handle used and leftoverchemicals in the prescribed manner.
! Stop the engine and turn off the electrical supplyat the main switch(es) before carrying out workon the electrical system.
! Clutch adjustments must be carried out with theengine stopped.

! Always use protective glasses or goggles whencarrying out work where a risk of splinters,grinding sparks, splashes from acid or otherchemicals is present. Your eyes are extremelysensitive; injury may cause blindness!
! Never start the engine with the valve coverremoved. There is a risk of personal injury.
! Never use start gas or similar products as astarting aid. They may cause an explosion in theinlet manifold. Danger of personal injury.
! Stop the engine before working on the coolingsystem.Marine engines: Close the sea cock / coolingwater inlet valve before work on the coolingsystem is begun.
! All fuels, as well as many chemicals, areflammable. Do not allow open flames or sparksin their vicinity. Gasoline, some thinners, andhydrogen gas from batteries are extremelyflammable and explosive when mixed with air inthe correct proportions. No Smoking! Ensurethat the work area is well ventilated and take thenecessary safety precautions before welding orgrinding work is begun. Always ensure thatthere are fire extinguishers close at hand in thework area.
! Make sure that oil, fuel-soaked rags, and usedfuel and oil filters are stored in a safe manner.Rags soaked in oil can spontaneously igniteunder certain circumstances. Used fuel and oilfilters are environmentally hazardous wasteand must be handed to an approved wastemanagement facility for destruction, as mustany used lubrication oil, contaminated fuel,paint residue, solvents, degreasers and washresidue.
! Batteries must never be exposed to openflames or electric sparks. Never smoke in thevicinity of the batteries; they generate hydrogengas when charged, which is explosive whenmixed with air. This gas is easily ignited andhighly explosive. A spark, which can be causedby incorrect battery connection, is sufficient tocause a battery to explode and cause damage.
Do not touch the connections during startattempts. Sparking hazard! Do not lean overbatteries.
! Never work alone when removing heavycomponents, even when using lifting devicessuch as locking tackle lifts. When using a liftingdevice, two people are usually required to dothe work - one to take care of the lifting deviceand the other to ensure that components arelifted clear and not damaged during the liftingoperations.
! Never transpose the positive (+) and negative(-) battery posts when installing batteries. Sucha transposition can result in serious damage toelectrical equipment. Refer to the wiringdiagram.Always use protective goggles when chargingand handling the batteries. Battery electrolytecontains sulfuric acid which is highly corrosive.Should the battery electrolyte come into contactwith unprotected skin, wash it off immediatelyusing soap and copious amounts of water. If youget battery acid in your eyes, flush at once withcopious amounts of water and seek medicalassistance immediately.
! The existing lugs on the engine should be usedfor lifting. Always check that the liftingequipment used is in good condition and has theload capacity to lift the engine (engine weightincluding gearbox or extra equipment). For safehandling and to avoid damaging componentsfitted to the top of the engine, the engine mustbe lifted with a correctly adjusted lifting boom.All chains or wires must run parallel to eachother and as perpendicular to the engine aspossible. If other equipment attached to theengine has altered its center of gravity, speciallifting devices may be needed to obtain thecorrect balance for safe handling. Neverperform any work on an engine that is onlysuspended from the lifting equipment.

! The components in the electrical and fuelsystems on Volvo Penta products are designedand manufactured to minimize the risk of fireand explosion. The engine must not be run inareas where there are explosive materials.
! Exercise extreme caution when leak-detectingon the fuel system and testing the fuel injectornozzles. Use eye protection. The jet from a fuelnozzle has very high pressure and greatpenetration power. Fuel can force its way deepinto body tissue and cause severe injury. Thereis a risk of blood poisoning (septicemia).
! Only use fuels and lubricating oilsrecommended by Volvo Penta. Refer to theOperator's Manual for the product in question.Use of fuels that are of a lower grade maydamage the engine, the injection pump and theinjectors. On a diesel engine, low grade fuel cancause the control rod to bind and the engine toover-rev, with the risk of engine damage andpersonal injury as a result. Low fuel and oilgrades may result in high service, maintenanceand repair costs.
! Never use a high-pressure washer for cleaningthe engine.Pay attention to the following when using a high-pressure washer on components other than theactual engine: Never direct the water jet atseals, rubber hoses or electrical components.
! Fuel delivery pipes must not be bent orstraightened under any circumstances. Cracksmay occur. Damaged pipes must be replaced.
! When working on the engine; perform leakageand function test as necessary.
