If this incline of the generator is exceeded, fuel may
leak out of the fuel tank.
4. Fill the oil tank (crankcase of the engine)
through the filling neck up to the oil level
mark with motor oil class of SAE 15W40.
Always check the oil level prior to starting the
generator.

WARNING
y
When handing oil, use suitable protective gloves because
oil is absorbed through the skin and is damaging to health.
The generator is supplied without oil and thus prior
to first putting it into operation, it is necessary to fill
it with oil so that the gauge on the oil cap (dipstick) is
fully submerged in oil when fully screwed in (fig. 12B).
For the purpose of pouring oil into the oil tank, screw
open the filling cap (fig. 12A) and using a funnel, pour
motor oil into the oil tank up to the level according to
(fig. 12B). Check the oil level on the gauge (dipstick)
after screwing it out of the oil tank.
Only check the oil level in the oil tank when the gene-
rator is standing level and only after an extended
period of time after the engine is turned off (at least 15
minutes). If you perform the oil level check too soon
after turning off the generator, not all the oil will have
flowed down the walls of the oil tank and the oil level
reading will not be reliable.
Use quality motor oils intended for lubricating four-
-stroke air-cooled petrol engines, e.g.
Shell Helix HX5
15 W-40, Castrol GTX 15 W40
or their equivalents,
with an SAE 15W40 viscosity class. Oils with a SAE
15W40 viscosity class ensure good lubrication pro-
perties at the temperatures in our climatic conditions.
Class SAE 15W40 oils can be purchased at fuel stations.
Only quality motor oil may be used in the generator.
Using different types of oils, e.g. vegetable oils, etc.,
is impermissible from the standpoint of inappropriate
lubricating properties.
RECOMMENDED SAE MOTOR OIL
VISCOSITY CLASSES BASED ON AMBIENT
TEMPERATURES (°C)
The graph (fig.13) specifies the motor oil classes for the
given temperature range in the case that Class SAE 14
W40 motor oil is not available.
Running the generator with an insufficient or excessive
amount of oil results in damage to the engine.
Never use oils intended for two-stroke engines in
the generator!
When the oil level is low, top it up using the same
brand and type of oil that is already contained in the
generator. Do not mix oils with a different SAE class.
5. Check the condition air filter.
Check the air filter for clogging and its condition every
time before putting the generator into operation
(the inspection and maintenance plan is provided in
chapter Cleaning and maintenance). Remove the air fil-
ter cover and check that the air filter is not missing and
its condition, that it is not clogged, damaged, etc. (fig.
14).
Clean the filter after every 50 motor hours or in
the event of operation in a dusty environment after
every 10 motor hours or more frequently according
to the instructions included later in the chapter
Cleaning and maintenance.
In the event of significant
clogging or wear and tear, replace it with a new origi-
nal filter (for part number see table 1). A clogged air
filter or operation of the generator without the air filter
will result in damage to the carburettor and the engine.
6. Through the sieve in the petrol tank filling
opening, pour clean lead-free car petrol
without oil. Use good quality, fresh lead-free
petrol with an octane number of 95 or 98 (e.g.
Lead-free 95).
Always pour fuel into the tank through the strainer
that is inserted in the fuel tank opening.
This will remove any potential mechanical particles
contained in the petrol, which could clog the fuel sys-
tem and carburettor.
Use good quality, fresh lead-free petrol with an octane
number of 95 or 98 (e.g. Lead-free 95).
y
Poor quality fuel has a negative effect on how the gene-
rator runs (e.g. problems with starting, engine runs irre-
gularly, lower engine power, faster clogging of the spark
plug, etc.).
y
A natural property of petrol is that it absorbs ambient
humidity and evaporates (weathers). Therefore, do not use
petrol in the generator that is older than one month from
the time it was purchased at the fuel station since old fuel
also has a negative effect on the way the generator runs.
Never use petrol that contains oil in the generator!
y
We recommend adding a petrol
conditioner to the petrol (petrol dewa-
tering fluid). It improves the properties
of the petrol, extends the lifetime of
the engine and reduces carbonisation
of the exhaust pipe and eliminates potential
starting problems, particularly when there is older
fuel in the petrol tank. Petrol conditioned can be
purchased at fuel stations. Based on our experience,
a proven conditioner is from the Wynn's brand
under the name DRY FUEL from the Belgian manu-
facturer. Based on our experience, it is sufficient to
preventively add 1/2 to 1 full cap of the above-men-
tioned conditioner into a full tank of petrol and to
mix it in with the petrol in the tank by moving the
generator or to mix it in by pouring in additional
petrol. If the conditioner is added to older fuel,
