Safety precautions for running the engine
Daily inspection
Always visually inspect the engine and engine
compartment before starting the engine and once
you have stopped the engine after running.
This will enable you to easily detect fuel, oil or
coolant leaks, or any other abnormalities which may
require rectification.
Refuelling
There is a risk of fire and explosion when refuelling.
The engine must be stopped and smoking is
prohibited.
Do not overfill the tank due to a risk of expansion,
and close the filler cap properly.
Use only fuel recommended in the workshop
literature. Fuel of the wrong grade could cause the
engine to malfunction or stop by preventing the
injection pump and injectors from operating as they
should.
This can cause damage to the engine and, possibly,
injury.
Hazardous gases
Only start the engine in a well ventilated area.
The exhaust gases contain carbon monoxide and
nitrogen oxides, which are toxic.
If it is run in an enclosed space, there should be an
effective device to extract exhaust gases and
crankcase gases.
Starter lock
If the control panel is not fitted with a key operated
switch, there should be a lock on the engine
compartment to prevent unauthorised starting of the
engine.
Alternatively, a lockable on/off master switch or
battery master switch can be used.
Starter spray
Never use starter spray or similar agents to help start
the engine. This can cause an explosion in the intake
manifold and possible injury.
Running
The engine must not be run in environments where
there is a risk of explosion as all of the electrical or
mechanical components can generate sparks.
Approaching a running engine always poses a safety
risk. Parts of the body, clothes or dropped tools can
get caught in rotating parts such as the fan and cause
injury.
For personal safety all rotating parts and hot
surfaces must therefore be shielded as much as
possible.
