Safety Information
Hot Surfaces and Fluids
There is always a risk of burns when working with a
hot engine. Beware of hot surfaces. For example: the
exhaust pipe and manifold, oil pan, starter element,
hot coolant, and hot oil in oil lines and hoses.
Always turn off the engine before starting service pro-
cedures. Avoid hot surfaces and liquids in supply lines
and hoses when the engine has just been turned off
and is still hot.
Cooling System
There is a risk of flooding when working on the sea-
water system. Turn off the engine and close the sea
cock (where installed) before starting work on the sys-
tem.
Avoid opening the filler cap for engine coolant system
(freshwater cooled engines) when the engine is still
hot. Steam or hot coolant can spray out as system
pressure is lost.
If opening the filler cap or drain/venting cock, or re-
moving a plug or engine coolant line from a hot en-
gine, open the filler cap slowly and release coolant
system pressure gradually; otherwise, steam or hot
coolant can spray out. Note that the coolant may still
be hot and can cause burns.
Fuel System
Always use protective gloves when tracing leaks. Liq-
uids ejected under pressure can penetrate body tis-
sue and cause serious injury. There is also a danger
of blood poisoning.
Always cover the alternator if it is located under the
fuel filter. The alternator can be damaged by spilled fu-
el.
Fuel filter replacement should be carried out on a cold
engine to avoid the risk of fire caused by fuel spilling
onto the exhaust manifold.

Lubrication System
Hot oil can cause burns. Avoid skin contact with hot
oil. Ensure that the lubrication system is not under
pressure before commencing work on it. Never start or
operate the engine with the oil filler cap removed; hot
oil could spray out.
Electrical System
Always stop the engine and break the current using
the main switches before working on the electrical
system. Isolate shore current to the engine block heat-
er, battery charger, or accessories mounted on the en-
gine.
Carbon Monoxide Poisoning
Only start the engine in a well-ventilated area. If oper-
ating the engine in an enclosed space, ensure that
there is proper ventilation in order to remove exhaust
gases and crankcase ventilation emissions from the
working area. Please see ""Station Wagon" Effect &
Carbon Monoxide" on page 10 for additional informa-
tion.
Chemicals
Most chemicals such as anti-freeze, rust-proofing
agents, inhibiting oils, degreasing agents, etc., are
hazardous to your health. Read and follow the instruc-
tions on the packaging.
Some chemicals such as inhibiting oil are flammable
and toxic if breathed. Ensure good ventilation and use
a protective mask when spraying.
Read and follow the instructions on the packaging.
Store chemicals and other hazardous materials out of
the reach of children. To protect the environment
please dispose of used or leftover chemicals at a
properly designated disposal site for destruction.
