General instructions
Introduction
The workshop manual contains technical data, de-
scriptions and repair instructions for products or prod-
uct versions noted in the table of contents, supplied
by Volvo Penta. Make sure you use the correct work-
shop literature.
Read the available safety information, "General in-
formation" and "Repair instructions" in the work-
shop manual before you start to do any service
work.
Important!
The following special warning signs are found in the
workshop manual and on the product.
WARNING! Warns for the risk of personal inju-
ry, major damage to product or property, or seri-
ous malfunctions if the instruction is ignored.
IMPORTANT! Is used to call attention to things
which could cause damage or malfunctions to
product 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 always
need to be observed and precautions which always
have to be taken, we have noted them below.
Make it impossible to start the engine by cutting
system current with the main switch(es) and
lock it (them) in the off position before starting
service work. Fix a warning sign by the helms-
man's seat.
All service work should normally be done on a
stationary 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. can
catch on rotating components and cause severe
injury.

Safety information
If work is done adjacent to a running engine, a
careless movement or a dropped tool can lead
to personal injury in the worst case. Be careful
with hot surfaces (exhaust pipes, turbos, charge
air pipes, starting heaters etc.) and hot fluids in
pipes and hoses on an engine which is running
or which has just stopped. Re-install all guards
which have been removed during service work,
before re-starting the engine.
Make sure that the warning or information labels
on the product are always clearly visible. Re-
place labels which have been damaged or paint-
ed over.
Engines with turbocharger: Never start an en-
gine without the air filter in place. The rotating
compressor turbine in the turbocharger can
cause severe injury. Foreign bodies in the inlet
pipe can also cause severe mechanical dam-
age.
Never use start spray or similar products as a
starting aid. Explosions could occur in the inlet
manifold. Danger of personal injury.
Avoid opening the coolant filling cap (on fresh
water cooled engines) when the engine is hot.
Steam or hot coolant could spray out. Open the
filler cap carefully, and release the excess pres-
sure in the cooling system. Be extremely careful
if a tap, plug or coolant hose has to be removed
from a hot engine. Steam or hot coolant can
stream out in an unexpected direction.
Hot oil can cause burns. Avoid skin contact with
hot oil. Make sure that the oil system is de-pres-
surized before doing any work on it. Never start
or run the engine with the oil filler cap removed,
because of the risk of oil spillage.
Stop the engine and close the sea cocks before
doing any work on the cooling system.
Only start the engine in a well-ventilated area.
When operated in a confined space, exhaust
fumes and crankcase gases must be ventilated
from the engine bay or workshop area.
