General instructions
The work methods described in the workshop manual
apply to work in a workshop environment. For this rea-
son, the reverse gear and drive are lifted out of the
boat.
The warning signs which occur in the workshop manu-
al (please refer to “Safety information” for their mean-
ings)
WARNING !
IMPORTANT !
NOTE !
are not comprehensive in any way, since we can not
foresee everything, since service work is done in high-
ly varying circumstances. For this reason, all we can
do is to point out the risks which we believe could oc-
cur due to incorrect work in a well-equipped workshop,
using work methods and tools tested by us.
In the workshop manual, all tasks for which there are
Volvo Penta special tools, are done using these tools.
Special tools are specially prepared to permit the saf-
est and most rational work methods possible. For this
reason, it is the responsibility of the person who uses
other tools or other work methods than those recom-
mended by us, to ensure that there is no risk of per-
sonal injury or material damage, and that they can not
cause any malfunctions.
In some cases, special safety regulations and user in-
structions are available for the tools and chemicals
mentioned in the workshop manual. These rules must
always be observed, so there are no special instruc-
tions about this in the workshop manual.
The majority of risks can be prevented by taking cer-
tain elementary precautions and using common
sense. A clean workplace and a clean engine elimi-
nate many risks of both personal injury and malfunc-
tion.
Above all, when work on fuel systems, lubrication
systems, induction systems, turbocharger, bearing
caps and seals is done, it is extremely important that
no dirt or other kinds of foreign particles are able to
get in, since this would otherwise cause malfunctions
or shortened repair life.
Our common responsibility
Each engine consists of a large number of collaborat-
ing systems and components. Any deviation of a
component from its technical specification can dra-
matically increase the environmental impact of an oth-
erwise good engine. For this reason, it is extremely
important that specified wear tolerances are main-
tained, that systems with adjustment facilities are cor-
rectly adjusted and that Volvo Penta Original Spares
are used for the engine. The times noted in the engine
maintenance schedule must be observed.
Some systems, such as components in the fuel sys-
tem, may require special competence and special test
equipment. For environmental reasons etc., some
components are sealed at the factory. It is only per-
missible to work on sealed components if you are au-
thorized to do such work.
Remember that most chemical products, incorrectly
used, damage the environment. Volvo Penta recom-
mends the use of biodegradable degreasers whenever
engine components are de-greased, unless otherwise
specified in the workshop manual. When working
aboard a boat, be careful to ensure that oils, wash
residue etc. are processed for destruction, and are not
inadvertently discharged with bilge water into the envi-
ronment.
