In this book and on the product you will find the following
special warning symbols.
WARNING! Possible danger of personal injury, exten-
sive damage to property or serious mechanical mal-
function if the instructions are not followed.
IMPORTANT! Used to draw your attention to some-
thing that can cause damage or malfunctions on a
product or damage to property.
Note: Used to draw your attention to important information
that will facilitate the work or operation in progress.
Below is a summary of the risks involved and safety pre-
cautions you should always observe or carry out when
operating or servicing the engine.
Immobilize the engine by turning off the power supply
to the engine at the main switch (switches) and lock it
(them) turned off before starting work. Set up a warn-
ing notice at the engine control point.
As a general rule all service operations must be car-
ried out with the engine stopped. However, some
work, for example certain adjustments require that the
engine is running when they are carried out. Ap-
proaching an engine which is operating is a safety
risk. Loose clothing or long hair can fasten in rotating
parts and cause serious personal injury.
Safety Precautions
If working in proximity of an engine which is operat-
ing, careless movements or a dropped tool can re-
sult in personal injury. Take care to avoid contact
with hot surfaces (exhaust pipes, Turbocharger
(TC), air intake pipe, starter heater etc.) and hot liq-
uids in lines and hoses on an engine which is run-
ning or which has just been stopped. Reinstall all
protective parts removed during service operations
before starting the engine.
Check that the warning or information labels on the
product are always clearly visible. Replace labels
which have been damaged or painted over.
Never start the engine without installing the air cleaner
(ACL) filter. The rotating compressor in the Turbo can
cause serious personal injury. Foreign objects enter-
ing the intake ducts can also cause mechanical dam-
age.
Never use start spray products or similar when start-
ing the engine. They may cause an explosion in the
inlet manifold. Danger of personal injury.
Avoid opening the coolant filler cap when the engine is
hot. Steam or hot coolant can spray out and the sys-
tem pressure will be lost. When needed, open the filler
cap slowly and release the pressure in the system. Be
very careful if a cock or plug or engine coolant line
must be removed when the engine is hot. It is difficult
to anticipate in which direction steam or hot coolant
can spray out.
Hot oil can cause burns. Avoid getting hot oil on the
skin. Ensure that the lubrication system is not under
pressure before carrying out any work. Never start or
operate the engine with the oil filler cap removed, oth-
erwise oil could be ejected.
Stop the engine before carrying out operations on the
engine cooling system.
Only start the engine in a well-ventilated area. If oper-
ating the engine in an enclosed area en- sure that
there is exhaust ventilation leading out of the engine
compartment or workshop area.
