IX. Care and maintenance
1. Before commencing maintenance tasks, turn off
the engine and position it generator on arigid
horizontal surface.
2. Allow the generator to cool down before perfor-
ming maintenance (servicing) tasks.
• ATTENTION
y Only original spare parts of the manufacturer may
be used for repairs of the generator.
 Regular inspections, maintenance, checks, audits and
adjustments in regular intervals are an essential prerequi-
site for ensuring safety and for achieving high performan-
ce of the generator. Table 2provides the plan of tasks that
must be performed in regular intervals by the operator
themselves and that may only be performed by an autho-
rised generator service centre for the HERON® brand.
 To extend the lifetime of the generator, we recom-
mend that acomplete inspection is performed after
1200 hours of operation, including repairs, covering
the following tasks:
y the same tasks according to the maintenance plan
after every 200 hours and the following tasks that
may only be performed by an authorised generator
service centre for the Heron® brand:
y inspection of the crankshaft, piston rod and piston
y inspection of collector rings, carbon brushes of the
alternator or shaft bearings

sensor will prevent the generator from starting up. The
presence of this sensor does not entitle the opera-
tor 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.
DIGITAL METER OF OUTPUT
VOLTAGE, FREQUENCY
AND OPERATION HOURS.
y The generator is equipped with adigital motor hours coun-
ter 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 from the first start of the generator, the out-
put voltage and frequency, (see fig.1, position 2).
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 voltage
on non-live parts, the generator meets the requirements
of the currently valid European Directive 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 species 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
the circuits of the generator and the connected electrical
device in the case where the connected electrical device
has Class I. protection or the electrical device is grounded,
where it is then also necessary to ground the generator
for the requirements of directive HD60364-4-4 (in the
Czech Republic it is norm ČSN332000-4-41) to be met.
Grounding must be performed using norm compliant
grounding devices and must be carried out by aperson
with the required professional qualications based on the
conditions where the generator is located and operated.
USING AN EXTENSION CORD
FOR CONNECTING ELECTRICAL
DEVICES TO THE GENERATOR
 The load capacity of the cables depends on the
resistance of the conductor. The longer the cable used,
the greater must be the cross-section of the conductor
(wire/s). Due to electrical power losses, the greater the
length of acable, generally the lower is the operating
performance at its end.
 According to norm ENISO8528-13, when using
extension cords or mobile distribution networks, the
resistance value must not exceed 1.5Ω. The total
length of cables with aconductor cross-section of
1.5mm
2
(for anominal current in the range >10A to
≤ 16A) must not exceed 60m. With aconductor cross-
-section of 2.5mm
2
(for anominal current in the range
> 16A to ≤25A) the length of the cable must not exce-
ed 100m(with the exception of cases, where the gene-
rator meets the requirements of protection by electri-
cal isolation in accordance with annex B(B.5.2.1.1.) of
norm ENISO8528-13.
According to the Czech norm ČSN 340350, the nominal
length of aflexible extension cable with awire cross-
-section of 1.0mm
2
Cu at anominal current of 10A
(2.3kW) must not be longer than 10m, an extensi-
on cable with acore cross-section of 1.5mm
2
Cu at
anominal current of 16A (3.68kW) must then be no
longer than 50m. According to this norm, the total
length of aflexible power cable including extension
cords should not exceed 50m(if, for example, this is an
extension cord with across-section of 2.5mm
2
Cu).
 For reasons of cooling, the extension cord must not be
wound up or wound on to aspool, but must be fully
unwound along its entire length in order to be cooled
by the temperature of the ambient environment.
OPERATION AT HIGH ABOVE SEA
LEVEL ALTITUDES
y At ahigher above sea level altitude (above 1000m
a.s.l.) the fuel:air ratio changes in the carburettor
towards flooding with fuel (insufficient amount of
air). This results in reduced performance, increased
fuel consumption, carbonisation of the engine,
exhaust pipe, spark plug and more difficult starting.
Operation at high above sea level altitudes also
negatively affects exhaust fume emissions.
y In the event that you wish to operate the generator at
an altitude greater than 1,000 metres above sea level for
an extended period of time, have the carburettor read-
justed at an authorised generator service centre for the
HERON® brand.
Do not adjust the carburettor yourself!
• ATTENTION
y Even with the recommended readjustment of the
generator's carburettor, the performance nevertheless
declines by about 3.5 % per every 305m of above sea
level altitude. Without performing the above-described
readjustments, the loss in performance is even greater.
y When the generator is operated at an above sea level
altitude that is lower than for which the carburettor
is set, the carburettor has alower fuel mixture, which
again results in aloss in performance. Therefore, it is
necessary to readjust the carburettor.
