General instructions
the lifting devise and other who makes sure that
components move freely and are not damaged
during lifting.
When you work aboard a boat, always make
sure that there is enough space for disassembly
where you are working, with no risk for personal
or material damage.
Components in the electrical system, the igni-
tion system (on petrol (gasoline) engines) and
fuel systems on Volvo Penta products have
been designed to minimize the risks of explo-
sion and fire. The engine must not be operated
in environments with adjacent explosive media.
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.
NOTE ! The fuel delivery pipes must not be bent,
twisted or tampered with in other ways. Change
damaged fuel delivery pipes.
Only use the fuels recommended by Volvo Pen-
ta. Please refer to the instruction book. The use
of fuel of inferior quality can damage the engine.
In a diesel engine, poor fuel can cause the regu-
lation rod to bind and the engine will over-rev,
entailing a strong risk of personal injury and ma-
chinery damage. Poor fuel can also lead to high-
er maintenance costs.
The existing lugs on the engine/reverse gear
should be used for lifting. Always check that the
lifting devises are in good condition and that
they have the correct capacity for the lift (the
weight of the engine plus the reverse gear and
extra equipment if installed).
The engine should be lifted with a customized or
adjustable lifting boom for safe handling and to
avoid damaging components on top of the en-
gine. All chains or cables should be parallel to
each other and should be as square as possible
to the top of the engine.
If other equipment connected to the engine has
altered its centre of gravity, special lifting devis-
es may be needed to obtain the correct balance
and safe handling.
Never do any work on an engine which just
hangs from a lifting devise.
Never work alone when heavy components are
to be dismantled, even when safe lifting devises
such as lockable blocks & tackle are used.
Even when lifting devises are used, two people
are needed in most cases. One who operates
