the fuel in a place inaccessible to children. The fuel fumes are highly inflammable.
• Check the air filter: make sure that it is in good conditions and free from dust and dirt. To reach the filter consult the engine user's and
maintenance manual.
ATTENTION: do not use the generator without the air filter: the life of the engine and the generator will be reduced!
• Activate the battery: fill the compartments to their maximum level with a 30/40% sulphuric acid solution and wait at least two hours
before using.
ATTENTION: do not touch the acid and do not smoke or use naked lights: battery fumes are highly inflammable. Keep the acid
out of reach of children.

STARTING THE GENERATOR (6.1):

Before starting the engine it is necessary to:
• Ensure that no appliance is plugged into the generator.
• For the petrol engine version use the choke for cold starts.
• For generators with electrical starters turn the key to the "START" position and release it as the machine starts.
• To start the recoil operated generators, pull the cord handle until resistance is felt, then pull energetically.
ATTENTION: Do not let the recoil handle rewind quickly. Guide it to prevent damage to the automatic winder.
• When the engine is running, switch off the choke.
• At this point the unit is ready for use.
NOTE: If the generator is used at high altitudes or temperatures, the air-fuel mix ratio may be too rich; this will cause higher consumption
and lower performance. Check the effective power of the generator by means of the following correction factors:
TEMPERATURE: Power drops an average of 2% every 5 degrees centigrade above a temperature of 20 degrees centigrade.
ALTITUDE: Power drops an average of 1% every 100 meters a.s.l. Above an altitude of 2000 m, contact the service centre of the engine's
manufacturing company to reset the combustion mixture if necessary.

USING THE GENERATOR (7.1):

NOTE: The generator, built to current standards, has been designed to satisfy a very wide range of applications.
Using the machine it should be remembered that every application is subject to exact electrical, accident prevention and sanitary
standards; for this reason the generator should be considered as an integral part of the complete installation, and should be designed,
tested and approved by qualified technicians and/or companies.
• In order to avoid electrical accidents, all connections to the distribution panel must be carried out by qualified technicians. Incorrect
connections can harm people and damage the generator.
• Protection against indirect contacts: all the generators, during normal working, follow the law of electrical separation; however,
they can be supplied with various protection options (ELCB, isometer) by the manufacturer on specific request, or they can be
protected in the same way during installation by the user.
It is important therefore, to follow the instructions as below:
1) Standard generators: protected by electrical separators. This equipment has a thermal protection device and/or a magnetothermal
device to protect against overload, over-current and short-circuit.
In these cases the Generator should under no circumstances be grounded using the terminal "PE" or with any other part of the generator.
2) Generator with optional switchboard (or with other devices installed by the user): protected by a circuit breaker which
automatically cuts off the power supply. It has thermal circuit breaker and/or magnetothermal switches combined with differential
circuit breakers or insulation monitors. In this case the generator must be connected to a ground plate through the terminal "PE", via an
insulated yellow - green conductor with suitable section.
IMPORTANT: in the event of differential circuit breakers installation, it is important for its correct working that:
A) On single-phase generators the neutral point that corresponds to the joint of the two main coils is also grounded.
B) On three-phase generators the neutral point that corresponds to the star point in the case of a star connection is also grounded. In the
case of a delta connection it is not possible to install a differential switch.
• The generator is preset for grounding the masses; a special screw, marked with the symbol PE, allows all the metal parts of the
generator set to be connected to a ground plate.
• Do not connect to the generator any appliances with unknown electrical specifications or with specifications different from those of the
generator (i.e. different voltages and/or frequencies).
• The electrical circuit of the generator is protected by a switch, which is either magnetothermal, magnetothermal-differential of thermal;
overload and/or a short-circuit will cut the flow of current immediately. To reset, disconnect all appliances, check the cause of the
short-circuit and/or overload and switch on.
• If using the generator as battery charger, place the battery at a distance of 1 m from the unit, making sure that the filling plugs are
removed from the cells. Take care to observe the battery polarities, incorrect connection of positive and negative poles could cause the
battery to explode.
ATTENTION: During charging, the battery gives off inflammable vapour. Therefore observe the maximum caution during charging
and keep children far away.
• With a star-delta switch the following options are available:
THREE PHASE 4OO V (full design load)
SINGLE PHASE 230 V (1/3 of design load)
THREE PHASE 230V (full design load)
SINGLE PHASE 230 V (2/3 of design load)
When set on "O" all power points are disconnected.
• Before setting the switch to any of the above, ensure that no appliances are connected to the generator. Be sure to set the switch to the
correct current as shown on the tag, in order to avoid damages to the appliances.
- When the generator is in use, do not place any objects on the frame or directly on the engine: any foreign bodies may impair performan-
ce.
• Do not hinder the normal vibrations that the generator makes when in use. The silent-blocks are of an adequate size to work properly.
