Start the engine according to the procedure in "Start-up of the
combustion engine".
Make sure that the electrical loads to be connected are switched
off .
Lift the power outlet (IX) cover and plug in the power cable of
the electrical load.
Switch on the connected electrical load.
Caution! If more than one electrical load is connected, switch on
each next load when the previous load starts running steadily
(i.e. at the rated speed, temperature, etc.).
If the power output is overloaded by an excessive power output
consumption, the power outlets of the power generator are iso-
lated from power; the engine will keep running. In the event of
an overload, switch off all the connected electrical loads, unplug
them from the power generator, wait until the power generator
circuits cool down, and press the overload breaker reset button.
Make sure that the total rated power of all connected electrical
loads does not exceed the rated power output of the power gen-
erator. Disconnect the electrical loads as required. Check if the
air intake and/or the air vents are obstructed. Check the power
generator's vicinity for anything which might obstruct the air in-
take / air vents.
Having made the checks and rectifi ed the problem, start the
power generator according to the procedure.
CAUTION! The overload breaker may trip when switching on a
connected electrical load; most electrical power loads start with a
power consumption exceeding their ratings. If the electrical pow-
er load is not defective, it might not be compatible with the power
generator's output.
Stopping the engine
Switch off the electrical load connected to the power generator.
Unplug the electrical load power cables from the power gener-
ator.
Move the engine ON/OFF switch to "OFF" / O.
Wait until the engine stops.
Close the fuel supply valve by rotating it to "OFF".
CAUTION! If you need to shut down the engine immediately in
the event of an emergency, move the engine ON/OFF to "OFF".
Operation at high altitude
The carburettor installed in the generator has been designed
for correct operation at an altitude not higher than specifi ed in
the technical data table. If you need to work at a higher altitude,
contact an authorized servicing centre to modify the carburettor.
Even after modifi cation of the carburettor, it is expected that the
power of the combustion engine will decrease, and consequent-
ly the generator's power will decrease by 3.5 % for every 300
meters of altitude increase above the limit given in the table.
The power drop will be greater when using a generator without a
modifi ed carburettor. The decrease in power is due to the dilution
of air as sea level altitude rises.
MAINTENANCE AND OVERHAUL
During the warranty period, the user cannot disassemble the de-
vice or replace other assemblies or components than those listed
below, as this will invalidate the warranty. Any irregularities found

GB
during the check or the operation signal the need for repair to be
done at the servicing centre.
After work has been fi nished, clean the housing, ventilation slots,
switches, additional handle grip and guards using e.g. a jet of
air (pressure not more than 0.3 MPa), or a brush or dry cloth
without the use of chemicals or cleaning liquids. Clean the tools
and holders with a clean, dry cloth.
Scheduled Inspections
Periodic inspection and maintenance of the following generator
assemblies must be carried out.
CAUTION! All maintenance must be carried out with the ma-
chine switched off and not running. It is also necessary to dis-
connect all electrical equipment from the generator.
CAUTION! If a service operation is not described below. This
means that the device must be serviced by a specialist servicing
point for this purpose.
CAUTION! Where solvent is used for cleaning, avoid contact of the
solvent with skin and eyes. Use personal protective equipment.

It is recommended to replace the fuel tank every three years. If
any leaks are detected in the fuel system, it is forbidden to use
