Safety information

Lifting the engine

The existing lugs on the engine should be used for lift-

ing. Always check that the lifting devices are in good

condition and that they have the correct capacity for

the lift (engine weight together with auxiliaries, if fit-

ted). The engine should be lifted with an adjustable

lifting boom for safe handling. All chains or cables

should be parallel to each other and should be as

square as possible to the top of the engine. Please

note that auxiliary equipment installed on the engine

could change its centre of gravity. Special lifting de-

vices may then be needed to obtain the correct bal-

ance and safe handling. Never do any work on an en-

gine which just hangs from a lifting devise.

Before starting

Re-install all guards which have been removed during

service work, before re-starting the engine. Make sure

that there are no tools or other objects left behind on

the engine.

Never start a turbocharged engine without the air filter

in place. The rotating compressor turbine in the turbo-

charger can cause severe injury. There is also a risk

that foreign bodies could be sucked in and cause ma-

chinery damage.

Fire and explosion

Fuel and lubrication oil

All fuel, most lubricants and many chemicals are

flammable. Always read and observe the advice on

the packages.

Work on the fuel system must be done with the en-

gine cold. Fuel leakage and spills on hot surfaces or

electrical components can cause fires.

Store oil and fuel soaked rags and other flammable

material in a fire-proof manner. Oil soaked rags can

self-ignite in certain circumstances.

Never smoke when filling fuel, lubrication oil or close

to fuel filling stations or the engine bay.

Non-original spare parts

Components in fuel systems and electrical systems

on Volvo Penta engines are designed and manufac-

tured to minimize the risk of explosions and fire, in ac-

cordance with applicable legal requirements.

The use of non-original spare parts can cause an ex-

plosion or fire.

Batteries

Batteries contain and give off an explosive gas, espe-

cially when charged. This gas is very flammable and

highly explosive.

Smoking, open flames or sparks must never occur in

or near to batteries or the battery locker.

Incorrect connection of a battery cable or start cable

can cause a spark which can be sufficient, in its turn,

to make the battery explode.

Start spray

Never use start spray or similar preparations to help in

starting an engine with air pre-heating (glow plugs /

starting heater). Explosions could occur in the inlet

manifold. Danger of personal injury.

Hot surfaces and fluids

A hot engine always offers the risk of burns. Be on

your guard against hot surfaces: the exhaust mani-

fold, turbocharger, oil pan, charge air pipe, starting

heater, hot coolant and hot lubricating oil in pipes,

hoses etc.

Chemicals

Most chemicals, such as glycol, rust preventer, con-

servation oils, degreasers etc. are hazardous. Always

read and observe the advice on the packages.

Some chemicals, such as conservation oils, are flam-

mable and also hazardous to breathe. Ensure good

ventilation and use a protective mask for spraying. Al-

ways read and observe the advice on the packages.

Store chemicals and other hazardous material out of

the reach of children. Hand in surplus or used chemi-

cals to a recycling station for destruction.

Lubrication system

Hot oil can cause burns. Avoid skin contact with hot

oil. Make sure that the oil system is de-pressurized

before starting work. Never start or run the engine with

the oil filler cap removed, because of the risk of oil

spillage.
