Warning
This symbol indicates a dangerous situation if the warning is not heeded.
Not following this instruction could result in non-serious injury or damage.
1.3.2 General advice
One of the fundamental safety considerations is observation of the interval between maintenance procedures (see maintenance
schedule). Furthermore, never attempt to carry out repairs or maintenance procedures without the necessary experience and/or tools.
When you take delivery of your generating set, check that it is complete and not damaged in any way. A generating set should be
handled gently, avoiding sudden movements, and the place where it is to be stored or used should be carefully prepared beforehand.
Warning
Before use, it is essential that you know how to stop the generating set immediately and that you thoroughly
understand all the controls and operations.
Never let other people use the generating set without giving them all necessary instructions beforehand.
Never let children touch the generating set, even when it is not in operation. Do not operate the generating set near animals (as it
could cause them to panic).
Never start the motor without an air filter or exhaust.
Never invert the positive and negative battery terminals (if fitted) when connecting them. Such an inversion can lead to severe damage
to the electrical equipment.
Never cover the generating set with any type of material while it is in operation or just after it has been turned off. Wait until the
motor is cold.
Never coat the generating set with oil in an attempt to protect it from corrosion. Some preservative oils are flammable. Also, some are
dangerous to inhale.
In all cases, respect the local regulations currently in place concerning the use of generating sets.
1.3.3 Safety guidelines to prevent electrocution
Danger
While they are in operation, generating sets produce electric current.
Connect the generating set to earth each time you use it, in order to prevent electrocution.
Never touch stripped cables or disconnected connectors. Never handle a generating set with wet hands or feet. Never expose the
equipment to liquid splashes or rainfall, and do not place it on wet ground. Always keep the electrical cables and the connections in
good condition.
Do not use equipment in a poor state of repair which could lead to electrocution or damage to the equipment.
Use a differential protection device between the generating set and the appliances if the cable or cables used are more than 1 metre in
length. This device must be positioned at a maximum distance of 1 metre from the generating set electrical sockets. Use flexible,
durable cables, with rubber sheathing, conforming to the IEC 60245-4 standard or equivalent cables. Do not connect the generating
set to other power sources, such as the mains. In specific cases where there is provision for a reserve connection to existing electrical
networks, this must only be carried out by a qualified electrician, who should take the operating differences of the equipment into
account, according to whether the public distribution network or generating set is being used.
Special circuit breakers designed for use with generating sets are used to prevent electrocution. If these circuit breakers need to be
replaced, circuit breakers with identical nominal ratings and specifications must be used.
1.3.4 Safety guidelines to prevent fire
Danger
Keep all inflammable materials (e.g.: petrol, oil, fabric etc.) out of the way when the generating set is in operation.
The motor should not be operated in areas containing explosive products. There is a risk of sparks forming where
all electrical and mechanical components are not shielded. Never cover the generating set with any materials while
it is operating or just after it has been switched off (wait for the motor cool down).
1.3.5 Safety guidelines for exhaust gases
Danger
Exhaust gases contain carbon monoxide, which is a highly toxic substance. This substance can cause death if it is
present in excessive concentrations in the air inhaled.
For this reason, always use the generating set in a well ventilated area, where gases will not be able to accumulate.
Good ventilation is required for your generating set to work properly. Without this, the motor would very quickly run at too high a
temperature, which could lead to accidents or damage to the equipment and to surrounding items. However, if it is necessary to
operate it inside a building, adequate ventilation must be provided, so that people and animals are not affected. It is imperative that
exhaust gases are discharged outside.

1.3.6 Filling with fuel
Danger
The fuel is highly flammable and its vapours are combustible.
Smoking, using a naked flame or producing sparks are forbidden while the fuel tank is being filled.
Filling should be carried out with the motor turned off. All traces of fuel should be wiped off with a clean cloth.
Always place the generating set on a flat, level and horizontal surface to avoid fuel spillage from the tank onto the motor. Storage and
handling of petroleum products must be carried out in accordance with the law. Close the fuel tap (if fitted) each time the tank has
been filled. Fill the tank using a funnel, taking care not to spill any fuel. Then screw the petrol cap back on to the fuel tank as soon as
filling is complete. Never top up fuel when the generating set is in operation or hot.
1.3.7 Safety guidelines against burns
Warning
Never touch the motor or the silencer while the generating set is in operation, or when it has just stopped.
Hot oil burns, avoid contact with the skin. Check that the system is no longer pressurised before carrying out any procedures. Never
start or run the motor when the oil filler cap is off as oil may splash out.
1.3.8 Safety guidelines for handling batteries
Danger
Never place the battery close to a flame or fire
Use only insulated tools
Never use sulphuric acid or acid water to top up the electrolyte level.
1.3.9 Protecting the environment
Never drain or discard used oil onto the ground, but put it into a designated container. As far as possible, try to avoid sound
reverberating through walls and buildings, as the noise will be amplified. If the exhaust silencer of your generating set is not fitted
with a spark arrester and you need to use it in wooded, bushy or uncultivated areas, be extremely careful and make sure that sparks do
not cause a fire (clear vegetation from a fairly large area where you wish to place your generating set).
1.3.10 Danger of moving parts
Warning
Never go near a moving part that is in operation if you have loose clothing or long hair that is not enclosed in a
protective hair net. Do not try to stop, slow down or impede a moving part when it is in operation.
1.3.11 Capacity of the generating set (overload)
Never exceed the rated load of the generating set (in Amps and/or Watts) when it is running continuously.
Before connecting and operating the generating set, calculate the electrical power required by the electric appliances (in Watts). This
electrical power rating is usually found on the manufacturer's plate on bulbs, electrical appliances, motors etc. The sum total of power
required by these appliances should not exceed the nominal power rating of the generating set.
1.3.12 Operating conditions
The stated outputs of the generating sets are obtained in example conditions according to ISO 3046-1:
+27°C, 100 m above sea-level, humidity level equal to 60 % or
+20°C, 300 m above sea-level, humidity level equal to 60 %.
Performance is reduced by approximately 4 % for every additional 10°C and/or approximately 1 % for every additional 100 m in
altitude.

3. Preparation before starting
3.1.Checking the oil level
Always check the engine oil level before starting.
Checking and topping up should be carried out with the generating set on a horizontal surface.
nRemove the grey-coloured plug-gauge (no. 1, Fig. B) on the exhaust side by unscrewing it, and wipe the gauge.
oInsert the gauge into the filler neck (no. 2, Fig. B) without screwing it up.
pVisually check the level and top up if necessary.
qUsing a funnel, fill the oil sump until it overflows.
rScrew the cap back up again tightly in the filler tube.
sCheck that there are no leaks.
tWipe off excess oil with a clean cloth.
3.2.Checking the fuel level
Danger
Stop the engine before filling up with fuel and fill up in a well-ventilated area.
Do not smoke, or bring naked flames or sparks near to the area where you are filling up with fuel or where the
fuel is stored.
Only use clean fuel without any water.
Do not overfill the tank (there should not be any fuel in the filler neck).
When you have filled up, ensure that the tank cap is closed correctly.
Take care not to spill any fuel when filling the tank.
Before starting up the generating set, and if any fuel has been spilt, make sure that it has dried and that the
vapours have cleared away.
Check the fuel level and top up if necessary:
nUnscrew the fuel tank cap (no. 2, fig A).
oFill the tank (no. 1, fig A) using a funnel, taking care not to spill petrol.
pScrew the cap back on to the fuel tank.
3.3.Earthing the generating set
To earth the generating set, use a 10 mm2 copper wire attached to the generating set earth connection and to an earthing rod of
galvanised steel set in the ground to a depth of 1 metre. This also dissipates the static electricity that builds up in the electrical
machines.
3.4.Positioning the generating set for operation
Place the generating set on a flat, horizontal surface which is firm enough to prevent the set sinking down (under no circumstances
should the set tilt any direction by more than 10°).
Choose a site that is clean, well-ventilated and sheltered from bad weather, and store the additional supplies of oil and fuel within
close proximity, although respecting a certain distance for safety.
4. Using the generator set
4.1.Starting procedure
nOpen the petrol tap by turning the control lever (no. 14, fig. A) to the right.
oPlace the knob of the choke (no. 15, fig. A) on closed position as shown on the illustration.
Note: Do not use the choke when the engine is warm or when the atmospheric temperature is high.
pPlace the engine switch (no. 10, fig. A) on "ON" or "I".
qSeize the starting handle (no. 13, fig. A) correctly and pull it slowly until some resistance is felt, then let it return gradually.
rTake the starting handle again correctly, then pull the cord sharply and rapidly (pull it right out, using both hands if necessary).
Allow the handle to return slowly by hand. If the engine has not started, repeat the operation until the engine starts by gradually
opening the choke.
sWhen the engine has started, gradually open the choke (no. 15, fig. A).
4.2.Operation
When the engine begins to heat up, gradually bring the knob of the choke (no. 15, fig A) to open position.
When the running speed of the generating set has stabilised:
nCheck that circuit breaker (no. 16, fig A) is engaged.
oConnect the plug(s) to the generating set socket(s).

4.3.Electric current voltage selection
nUnplug the connected devices if necessary
oPut the switch on the desired voltage (no. 17, diag A), then plug back the devices on the sockets
4.4.Switching off
Warning
When the generating set is turned off, the engine continues to give off heat.
Appropriate ventilation should be provided after the generating set is turned off.
To stop the generating set urgently, place the engine switch on "OFF" or "О".
nTake the plugs out of the sockets and allow the engine to run without any charge for 1 to 2 minutes.
oPlace the engine switch (no. 10, fig. A) on "OFF" or "О" and the set will stop.
pClose the fuel tap (no. 14, fig. A).
5. Safety features (if fitted, see specifications table)
5.1.Oil cut-out
This mechanism is designed to prevent any damage to the motor resulting from lack of oil in the motor sump. It automatically cuts out
the motor. If the motor stops and will not restart, check the motor oil level before looking for any other cause of the problem.
5.2.Circuit breaker
The electrical circuit of the set is protected by several magnetothermal, differential or thermal cut-out switches. Any overload and/or
short circuits cause the supply of electrical energy to be cut.
6. Maintenance schedule
6.1.Reminder of use
The maintenance interval frequency and the operations to be carried out are outlined in the maintenance programme.
However, it should be added that it is the environment in which the generating set is operating which determines this programme.
Accordingly, if the set is used in extreme conditions, shorter intervals between maintenance procedures should be adopted.
These maintenance schedules apply only to generating sets running on fuel and oil, that conform to the specifications given in this
booklet.
