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 servic-
ing point for this purpose.
CAUTION! Where solvent is used for cleaning, avoid contact of
the solvent with skin and eyes. Use personal protective equipment.

(*) A higher frequency is recommended in case of use in dusty environments.
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 the generator.
Maintenance of the air fi lter (III)
CAUTION! Do not operate the power generator without a cor-
rectly installed air fi lter or with a defective air fi lter. Otherwise
the combustion engine may aspirate impurities that would nor-
mally settle on the air fi lter. Impurities can lead to malfunctions
or, ultimately, cause a failure of the power generator.
Release the knob and remove the air fi lter cover. Remove the
fi lter and clean it in a non-fl ammable solvent, then thoroughly
squeeze out the solvent.
Soak the air fi lter with clean engine oil and squeeze it out so
that the fi lter remains slightly moist only.
Install the air fi lter in place and close the air fi lter cover with the knob.
Maintenance of the spark plug
Disconnect the cable from the spark plug.
Remove the spark plug with the spark plug wrench (XX).

Use a wire brush to clean carbon deposits off the electrodes
(so-called combustion deposits).
Check the distance between the electrodes from 0.7 mm to 0.8
mm. (XXI)
If burned electrodes or the ceramic casing is broken, replace
the spark plug with a new one.
Screw in the spark plug. Connect the cable to the spark plug.

Care must be taken when changing the oil. As soon as the en-
operation
gine stops, the oil is hot and can cause burns.
Each oil tank has a drain opening. Place a container with a capac-
ity greater than that of the oil tank underneath the drain opening.
X
Unscrew the drain valve (XXIII) completely using a wrench. Al-
low the oil to fl ow into the tank and then screw in the drain valve
using a wrench. Wipe any oil residue dry.
Top up the oil according to the procedure described under
"Checking the oil level".

CAUTION! Dispose of used motor oil in accordance with the
local regulations. It is forbidden to spill engine oil into the sewer
system.

Maintenance of the fuel fi ller fi lter
Remove the fuel fi ller cap. Take out the fuel fi ller fi lter. Clean the
fuel fi ller fi lter using extraction petrol. Dry with a soft, clean cloth.
Install the fi lter in the fi ller opening. Close the fuel fi ller cap.
CAUTION! The fi lter walls are made of fi ne mesh. Care must
be taken during maintenance to ensure that they are not dam-
aged. If the fi lter is damaged, replace it with a new one that is
free of damage before resuming operation.

Storage of the power generator
If you need to store the power generator for a short time (less

than 10 days), stop the engine, unplug all electrical loads, and
hours
close the fuel supply valve.
If the power generator will be stored for more than 10 days,
follow the procedure below.
Move the engine switch to the O - off position.
Remove the fuel fi ller cap and drain fuel from the tank with a
suitable pump. Close the fuel fi ller cap.
Start the engine according to the procedure in "Start-up of the
combustion engine".
Do not plug in any electrical loads. Let the engine running until
it stalls to stop without fuel. The running time will depend on
how much fuel remains in the fuel tank and the fuel supply lines.
Move the engine switch to the O - off position.
Close the fuel supply valve by rotating it to "OFF".
Remove the spark plug from the cylinder. Add a table spoon of
engine oil through the empty spark plug port on the cylinder.
Use the engine oil with the viscosity listed in the product spec-
ifi cations table.
Screw in the spark plug. Pull the starter pull cord so that the
engine cranks through a few revolutions and the cylinder piston
is lubricated. Stop pulling the starter pull cord when you feel
the compression.
Regardless of the storage time, you should always:
Clean the outside of the generator with a soft cloth, brush or
