Useful information while operating the machine.
ATTENTION – DANGER!
IMPORTANT!
ELECTRICAL SAFETY 1.1
The device generates electricity. Follow safety precautions
to avoid electric shock.
As exhaust gases contain poisonous carbon dioxide (CO2)
and carbon monoxide (CO) gases which are dangerous
for life, it is strictly forbidden to install the generator in
residential buildings, premises connected to residential
buildings by a common ventilation system, other rooms
from which exhaust gases may enter living premises.
Using device for other purposes deprives the right for
free warranty.
ATTENTION – DANGER!

Be careful. Do not operate the generator, if you are tired,
under the inuence of drugs or alcohol. Inattention may
cause a serious injury.

PRECAUTIONS WHEN WORKING WITH
GASOLINE GENERATOR 1.2
The generator can be connected only in parallel with the 48-54V battery! Disconnect the load before you
stop the engine. Only unleaded gasoline is recommended for the generator! It is forbidden
to use kerosene or other fuel types. Before running the generator, it is necessary to dene the place and
means of its emergency stop. Do not refuel the running generator.
Fuel contaminates the land and groundwater. Do not
allow the leaking gasoline from the tank!
ATTENTION – DANGER!

*Fuel consumption depends on many factors, such as load, fuel quality, season, altitude, technical condi-
tion of the generator.
The optimal operating conditions are ambient temperature of 17-25°C, barometric pressure of 0.1 MPa
(760 mm Hg), and relative humidity of 50-60%. Under these environmental conditions, the generator can
provide maximum performance in terms of the declared specications.
In the event of deviations from these environmental indicators, the generator performance may vary.
GENERATOR OPERATION 4
Make sure that the control panel, the blinds and the un-
derside of the generator are well cooled and protected
against the ingress of small solids, dirt, and water. Im-
proper operation of the cooler can cause damage to the
motor, generator or alternator.
IMPORTANT!

SPECIFICATIONS 3

OVERLOAD INDICATOROVERLOAD INDICATOR
The overload indicator lights up when the connected generator is overloaded, the inverter control unit
overheats or the output voltage rises.
In this case, you must perform the following steps:
1. Turn off all connected electrical appliances and stop the engine.
2. Reduce the total power of the connected devices until the nominal power of the generator is reached.
3. Check if the vent grid is clogged. Remove excess dirt or debris, if any.
4. After checking, start the engine.
The overload indicator may light up within several sec-
onds after start-up. However, this is not a malfunction.
IMPORTANT!
CHECKING THE FUEL LEVELCHECKING THE FUEL LEVEL
1. Unscrew the fuel cap and check the fuel level in the tank.
2. Fill the fuel tank to the fuel filter level.
3. Tighten the fuel cap securely.
Recommended fuel:Recommended fuel: unleaded fuel.
Fuel tank volume:Fuel tank volume: see specifications table.
CHECK BEFORE GETTING STARTED 5
Wipe up spilled fuel immediately with a clean, dry, soft
cloth, as the fuel may harm painted surfaces or plastic
parts.
IMPORTANT!
CHECKING THE OIL LEVELCHECKING THE OIL LEVEL
The generator is transported free of motor oil. Do not start the engine until it is filled with sufficient amount
of motor oil.
1. Unscrew the oil dipstick and wipe it out with a clean cloth.
2. Insert the dipstick without screwing it in.
3. Check the oil level by a mark on the oil dipstick.
4. Add oil if its level is below the mark on the oil dipstick.
5. Screw on the dipstick.
Recommended motor oil:Recommended motor oil: SAE 10W-30, SAE 10W-40.
Motor oil quantity: Motor oil quantity: see specifications table.
FILL TO HEREFILL TO HERE
Use only unleaded gasoline. Using leaded gasoline can
cause serious damage to the inside of the engine.
IMPORTANT!
GETTING STARTED 6
Do not change the controller settings in terms of the
amount of fuel or speed governor (this adjustment
was made at the factory). Otherwise, this may result in
changes in the engine operation or its failure.
IMPORTANT!

FUEL FILTER 15
1. Remove the fuel tank cap and fuel lter.
2. Clean the lter with gasoline.
3. Wipe the lter and replace it.
4. Replace the fuel tank cap.
Make sure that the fuel tank cap is tight.
Never use gasoline while smoking or in the immediate
vicinity of an open flame.
IMPORTANT!
To drain gasoline from the carburetor, turn off the fuel
valve and wait until the generator has cooled down
sufficiently. Place a drip pan under the carburetor
and loosen the drain screw on the carburetor (see
fig.). Make sure that no fuel leaks onto the generator.
Tighten up the screw again.

Match the protrusion of the flame arrester to the hole
in the pipe damper.
IMPORTANT!
DAMPER AND FLAME ARRESTER
MAINTENANCE 14
The engine and damper will get very hot after the generator has been started. Do not touch the engine or
damper with any part of your body or clothing during inspection or repair until they have cooled down.
Remove the screws and then pull the protective cover towards you. Loosen the bolts and remove the cover,
screen and ame arrester of the damper. Descale the screen and ame arrester of the damper with a wire
brush.Inspect the screen and ame arrester of the damper. Replace them if they are damaged. Replace
the ame arrester. Replace the screen and cover of the damper. Replace the cover and tighten the screws.
SPARK PLUG VERIFICATION:SPARK PLUG VERIFICATION:
1. Remove the cap from the spark plug.
2. Remove the spark plug by means of a corresponding spanner.
3. Examine the spark plug. If is is shattered – it is necessary to replace it.
Recommended replacement spark plugs – F7TC.
4. Measure the gap. It has to be within range 0.7-0.8 mm.
5. In case of repeated use, the spark plug has to be cleaned by means of a metal brush.
After that – set the correct gap.
