SAFETY INSTRUCTIONS 
FOR EVOLUTION ENGINE
a. Petrol or diesel powered engines must never 
be used in unventilated closed spaces. The 
exhaust fumes produced are highly toxic and can 
cause ‘Carbon Monoxide Poisoning’ which will 
cause drowsiness and ultimately death. It is only 
permissible to run a petrol engine indoors if the 
building can be very well ventilated and the exhaust 
fumes can be captured and ducted to the outside 
through an exhaust extraction/scavenger system. 
b. The engine should be positioned on a firm 
level surface. The wheels should be locked, so 
that the engine cannot move during operation.
c. The engine should not be run at speeds 
that exceed the maximum speed on the rating 
plate. Operating an engine at excessive speeds 
increases the likelihood of component failure and 
consequent accidents.
d. Do not tamper with components that 
regulate the engines speed. You may alter the 
factory set running parameters.
e. Use only the type of fuel listed in this 
Instruction Manual. Using fuel with an octane 
rating less than that specified can lead to 
excessive engine wear and premature engine 
failure.
f. Keep the area around the engine clear, clean 
and tidy. Never allow any combustible material 
(timber, plastic, cardboard, canvas etc) near a 
running engine.
g. Do not use in or near to potentially explosive 
atmospheres. Dust laden atmospheres as can 
be found in some industrial buildings (Flour Mills, 
Timber Mills) have an explosive potential.
h. Regularly check the fuel system for leaks. 
Hoses and unions should be checked for 
deterioration or chafing. Check the fuel tank for 
damage or for a poorly fitting or worn fuel cap. Any 
defects must be rectified before the engine is used.
i. Always stop the engine and allow it to cool 
down before refuelling. Try to avoid any fuel 
spillage (often caused by ‘overfilling’ the tank) 
and clean up any spilt fuel immediately. The 
application of dry sand is an effective way of 
neutralising fuel spills. 
Do not allow sand to come into contact with any 
part of the engine
k. Do not allow the engine to run out of fuel 
while a generator under load is attached. Surging 
of the engine as it uses the last of the fuel could 
cause damage to connected electrical equipment.
l. When transporting the engine in a vehicle 
ensure that the fuel tap is turned off. To 
minimise the risk of fuel spillage the engine 
should be secured by ropes etc to the load area 
of the vehicle so that it cannot move during 
transportation. The engine should be secured in 
as level an attitude as possible.
m. For long term storage we recommend that 
the fuel system of the engine is drained. During 
long term storage additives in modern fuels can 
precipitate from the fuel and block jets and valves 
in the fuel system.
n. Store the machine in a secure and well 
ventilated area. Unauthorised personnel should 
not have access to this machine.
SAFETY INSTRUCTIONS FOR FUEL FILLING
 
a. Select level bare ground, remote from any 
buildings as a refuelling station. Ensure that there 
is no combustible material in the immediate vicinity.
b. Smoking, using a naked flame or producing 
sparks is strictly forbidden whilst refuelling. 
Petrol is highly flammable and its vapours are 
combustible.
c. Ensure that the fuel tap is turned ‘off’. This 
will ensure that fresh fuel does not ‘flood’ the 
engines carburettor.
d. The engine must be turned ‘off’ and 
allowed to cool before refuelling is attempted. 
Inadvertent fuel spillage onto a hot engine can 
result in the risk of fire.
e. Any fuel spills must be dealt with 
immediately. If petrol contaminates any 
clothing the operator must change clothes. Do 
not rely on the fuel evaporating from the clothes. 
Wash or launder the clothing when the fuel has 
evaporated from the material.
f. The use of a funnel during refuelling is 
recommended. Use of a funnel will minimise the 
risk of fuel spillage.
g. Fill the tank with the correct grade of 
unleaded fuel to a level approximately half 
way up the fuel filter. Pour the fuel into the tank 
carefully and do not try to fill the tank completely. 
Pour the petrol slowly to avoid air traps during 
filling that could cause fuel spillage.
h. Check the fuel tank cap, and replace as 
soon as refuelling is completed. The cap has a 
bayonet type connection. Check that it is correctly 
installed and seated before slowly turning on the 
fuel tap.
