sections of the Workshop Manual:
Safety Precautions
General Information
Repair Instructions
Below is a summary of the risks involved and sa-
fety precautions 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 (switch-
es) before starting work. Put a warning notice at
the engine control panel.
Generally, all service operations must be car-
ried out with the engine stopped.
However, some work, for example certain adju-
stments requires that the engine is running when
they are carried out.
Approaching an engine, which is operating, is a
safety risk. Loose clothing or long hair can fas-
ten in rotating parts and cause severe personal
injury.
Take care to avoid contact with hot surfaces
(exhaust pipes, turbocharger, air intake pipe, st-
arter element etc.) and hot liquids in lines and
hoses on an engine that is running or has just
been stopped. Reinstall all protective parts re-
moved during service operations before starting
the engine.
Check that the warning or information labels on
the product are always clearly visible. Replace
labels that have been damaged or painted over.
Never start the engine without installing the air
cleaner filter. Foreign objects entering the intake
ducts can also cause mechanical damage.
Never use ether or similar products when start-
ing the engine. They may cause an explosion in
the inlet manifold and causing personal injuries.
Only start the engine in a well-ventilated area.
If operating the engine in an enclosed area ma-
ke sure that the exhaust is leading out of the en-
gine compartment and working area.
Avoid opening the coolant filler cap when the en-
gine is hot, when hot steam or coolant might sp-
ray out. If the filler cap must be open, slowly re-
lease the pressure in the system. Be very car-
eful, it is difficult to anticipate in which direction
hot steam or coolant can spray out.

red likely to occur as a result of incorrect working
methods in a well-equipped workshop using working
methods and tools tested by AB Volvo Penta.
