Safety rules for operation and maintenance
Daily checks
Make it a habit to give the engine and engine bay a
visual check before starting
(before the engine is
started ) and after operation ( once the engine has
stopped ). This helps you to quickly discover whether
any leakage of fuel, coolant, oil or any other abnormal
event has happened, or is about to happen.
Starting lock
If the instrument panel does not have a key switch,
the engine room must be lockable, to prevent unau-
thorized persons from starting the engine. Alterna-
tively, a lockable main switch can be used.
Carbon monoxide poisoning
Only start the engine in a well ventilated area. When
operated in a confined space, exhaust fumes and
crankcase gases must be ventilated.
Hot surfaces and fluids
A hot engine always increases the risk for burns. Be
on your guard against hot surfaces: the exhaust mani-
fold, turbocharger, oil pan, charge air pipe, starting
heater, hot coolant and hot lubricating oil in pipes,
hoses etc.
Cooling System
Avoid opening the coolant filling cap when the engine
is hot. Steam or hot coolant can spray out and cause
scalding, at the same time as the pressure built up is
lost.
If the filler cap, coolant hose etc., still has to be opened
or removed when the engine is hot, undo the filler cap
slowly and carefully, to let the pressure out before
removing the filler cap completely and starting work.
Note that the coolant can still be hot and cause scald-
ing.
Fuel filling
There is always a risk of fire and explosion during fuel
filling. Smoking is forbidden, and the engine should be
stopped.
Never overfill the tank. Shut the tank cap securely.
Only use the fuel recommended in the instruction
book. The wrong grade of fuel can cause serious mal-
functions, power loss or stop the engine.
Fuel and lubrication oils
Always protect your hands when searching for leaks.
Fluids which leak under pressure can force their way
into body tissue and cause severe injury. There is a
risk of blood poisoning (septicemia).
Only use the fuel recommended in the Operators
Manual. The wrong grade of fuel can cause malfunc-
tions or stop the engine. In a diesel engine, it can also
cause the injection pump to seize and the engine will
over-rev, entailing a strong risk of personal injury and
machinery damage.
Always cover the alternator if it is located beneath the
fuel filters. Fuel spillage can damage the alternator.
Always change the oil, oil filter and fuel filter at the
specified intervals.
Operation
The engine must not be operated in environments
which contain explosive media since none of the elec-
trical and mechanical components are explosion
proof.
Going close to a running engine is a safety risk. Hair,
fingers, loose clothes, or dropped tools can catch on
rotating components and cause severe injury.
When engines are supplied without touch guards, all
rotating components and hot surfaces must be pro-
tected after installation in their application, if neces-
sary for personal safety.
