Safety precautions for maintenance and service

Preparations

Knowledge base

The Instruction Manual contains instructions on how

to carry out the commonest maintenance and service

operations safely and correctly. Read them carefully

before starting work.

Service literature for more extensive work can be ob-

tained from your Volvo Penta dealer.

Never undertake an operation if you are not complete-

ly sure how to do it. Contact your Volvo Penta dealer

for assistance instead.

Stopping the engine

Stop the engine before the engine compartment cover

is opened or removed. Unless otherwise specified all

maintenance and service must be carried out with the

engine stopped.

Immobilize the engine by removing the ignition key,

turning off the power supply with the main switch and

locking it in the OFF position. Fix a warning that work

is being undertaken to the control position.

Approaching a running engine is dangerous. Loose

clothing, long hair, fingers or tools can get caught in

rotating parts and cause serious personal injury.

Volvo Penta recommend that all servicing with the

engine running be undertaken by an authorized Volvo

Penta workshop.

Lifting out the engine

Use the lifting eyes mounted on the engine/reverse

gear when lifting the drive unit. Always check that lift-

ing equipment is in good condition and has sufficient

load capacity to lift the engine (engine weight includ-

ing reverse gear and any extra equipment installed).

For safety reasons the engine should be lifted with an

adjustable lifting beam. All chains and cables should

run parallel to each other and as perpendicular as

possible to the top of the engine. Note that extra

equipment mounted on the engine can change its

center of gravity. Special hoists may be necessary to

balance the engine and make handling it safe. Never

carry out work on an engine suspended on a hoist.

Before starting the engine

Reinstall all protective components that have been

removed before starting the engine. Check that no

tools or other objects have been left on the engine.

Never start a turbocharger engine without installing

the air cleaner (ACL). The rotating compressor in the

turbocharger (TC) can cause serious personal injury.

Foreign objects may be sucked into it causing me-

chanical damage.

Fire and explosion

Fuel and lubricating oil

All fuels, most lubricating oils and many chemicals

pose a fire hazard. Read and follow the instructions

on packaging.

Work on the fuel injection system must be carried out

on a cold engine. A fuel leak or spill onto a hot sur-

face or an electrical component can cause a fire.

Store oil and fuel soaked rags and other flammable

material in fireproof conditions. In certain circum-

stances oil soaked rags can spontaneously combust.

Never smoke when refueling, changing the oil or close

to filling stations or in the engine compartment.

Non-original components

The components in the fuel injection system, ignition

system (petrol engines) and electrical system in Volvo

Penta products are designed and manufactured to

minimize the risk of fire and explosion.

Using non-original Volvo Penta parts which do not

meet the above standards, can result in fire or explo-

sion on board.

Batteries

Batteries contain and produce oxyhydrogen, espe-

cially when they are being charged. This gas is easily

ignited and highly volatile.

Never allow a naked flame or sparks near the bat-

teries or battery compartment.

Incorrect connection of a battery lead or jump lead

can cause a spark which is sufficient to cause the

battery to explode.

Start spray

Never use start spray or similar agents to start an en-

gine with pre-heating (glow plugs/start element). The

starter element may cause an explosion in the intake

manifold. Danger of personal injury.

Hot surfaces and liquids

When the engine is at operating temperature there is

always a danger of burns. Avoid hot surfaces. For ex-

ample: exhaust manifold, turbocharger (TC), oil sump,

start element, hot coolant and hot lubricating oil in

pipes and hoses.
