VI. Turning off
the generator – putting
out of operation
1. Set the circuit breaker of the generator to the
"OFF" position.
2. Set the power switch to the "OFF" position.
3. Disconnect all electrical devices from the outputs
of the generator.
4. Shut off the fuel supply using the fuel valve.
If it is required to quickly shut off the generator,
first of all set the power switch to the "OFF" posi-
tion and then set the circuit breakers to the "OFF"
position. Then perform all the remaining steps.

ATTENTION
y
Closing the fuel supply to the carburettor is necessary,
otherwise petrol could pass through the petrol lines to the
engine's cylinders, namely when transporting or handling
the engine, and then it is necessary to have the engine's
cylinders cleaned out at an authorized service centre, for
which the right of a cost-free repair does not apply.
VII. Additional
information for the use
of the generator
CONTENT OF OXYGENOUS
COMPOUNDS IN THE FUEL
The content of oxygenous compounds in lead-free
car petrol must meet the requirements of the norm
EN 228+A1. Under no condition prepare the fuel blend
yourself but instead procure it only at a fuel station. Do not
modify the composition of the purchased fuel (excluding
the use of a fuel conditioner). Use only good quality lead-
-free car petrol. If you have any doubts about the composi-
tion of the fuel, request information about its composition
at the fuel station. Inappropriate fuel may damage the
engine without any right to a free warranty repair.
OIL SENSOR AND MONITORING
THE OIL AMOUNT
The generator is fitted with an oil sensor (fig. 21) that
shuts off the engine when the oil level falls below a criti-
cal limit, and thus prevents damage to the engine resul-
ting from insufficient lubrication.
The presence of this
sensor does not entitle the operator to omit regular
checks of the amount of oil in the engine's oil tank.
The oil sensor must not be removed from the generator.
CIRCUIT BREAKERS FOR VOLTAGE
CIRCUITS (POWER SOCKETS)
If during the use of the generator, electrical current
stops being supplied despite the engine still running,
this may be the result of the circuit breaker on the vol-
tage circuit being overloaded, see chapter "Technical
specifications".
a) In such a case, first turn off the engine of the generator
and disconnect it from all electrical devices.
b) Identify and remedy the cause of the overloading or
short circuit. Check that the power input of the con-
nected electrical device is within the limit of the opera-
ting power output of the generator. If the fault is cau-
sed by a fault inside the generator then do not use the
generator and have it repaired at an authorised service
centre for the
HERON®
brand.
c) Set the circuit breaker to the "OFF" position.
d) Connect electrical devices to the generator.
e) Start the generator.
f) Set the circuit breaker to the "ON" position.
DIGITAL METER OF OUTPUT
VOLTAGE, FREQUENCY
AND OPERATION HOURS
y
The generators are equipped with a digital motor hours
counter from the last start (the counter is automatically
reset to zero when the engine is turned off) as well as a
total motor hours counter (symbol "H"), the output vol-
tage (symbol "V") and frequency (symbol "Hz"), see fig.
6, position 9.
It is possible to use the button on the control panel to
switch between the individual measured values.
GROUNDING THE GENERATOR
y
In terms of protection against dangerous contact vol-
tage on non-live parts, the generator meets the requi-
rements of the currently valid European Directive HD
HD 60364-4-4 for protection by electrical isolation. The
requirements of this directive are entered into national
electro-technical norms of the given country (in the
Czech Republic this is norm ČSN 33 2000-4-41 including
valid annexes, if they exist).
y
Norm EN ISO 8528-13, which specifies safety require-
ments for generators, requires that the user's manual of
the generator includes the information that the genera-
tor does not need to be grounded in the case where the
generator meets the aforementioned requirements for
protection by electrical isolation.
y
The grounding terminal with which the generator is
equipped is used for unifying the protection between
