RECOMMENDED SAE MOTOR OIL VISCOSITY
CLASSES BASED ON AMBIENT TEMPERATURES (°C)
 The graph (fig. 5) specifies the motor oil classes for the
given temperature range in the case that Class SAE
15W40 motor oil is not available.
y Check the oil level on the gauge (dipstick) after scre-
wing it out of the oil tank.
 Only check the oil level in the oil tank when the pres-
sure washer is standing on a horizontal 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 engine, not
all the oil will have flowed down the walls of the crank-
case and the oil level reading will not be reliable.

ATTENTION:
y Wipe dry any spilled oil. Use protective gloves to pre-
vent your skin coming into contact with oil. In the event
that oil does comes into contact with skin, thoroughly
wash the affected area with soap and water.
OIL SENSOR AND MONITORING THE OIL AMOUNT
 The pressure washer is fitted with an oil sensor (Fig. 2,
position 11) that shuts off the engine when the oil level
falls below a critical limit, and thus prevents damage
to the engine resulting from insufficient lubrication. In
the event that there is no oil in the crankcase, the oil
sensor will prevent the engine from starting up. The
presence of this sensor does not entitle the operator
to omit regular checks of the amount of oil in the
engine's oil tank.
 The oil sensor must not be removed from the pressure
washer.
4. Check the condition air filter.
 Check the condition of the air filter and whether it is
clogged before putting the pressure washer into ope-
ration. A clogged air filter or operation of the pressure
washer without the air filter will result in damage to
the carburettor and the engine. A clogged air filter pre-
vents the supply of a sufficient amount of combustion
air to the engine and leads to the carbonisation of the
engine, spark plug and exhaust pipe.
1) To access the air filter, screw off the wing nut on the air
filter cover and remove the cover (fig. 6a).
2) Take the cover off the central shaft and inspect.
Clean the filter after every 50 motor hours of
operation or in the case of operation in a dusty
environment after every 10 motor hours or more
frequently. The filter consists of a foam pre-filter,
which captures coarser dirt and prevents the rapid
clogging of the folded paper filter behind the
metal grille. The procedure for cleaning the filter is
provided in chapter Cleaning and servicing.
In the event of damage or substantial clogging,
replace the filter with a new original one (part no.
8896351C).

3) To insert the filter proceed in reverse sequence. Check
that the plastic cover is correctly seated.
5. Through the strainer in the petrol tank fil-
ling opening, pour clean lead-free car petrol
without oil.
 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 carburettor and the fuel system.
y Petrol is highly flammable and very volatile. Petrol or its
fumes may very easily ignite, and therefore do not
smoke when handling petrol and prevent access to any
flame or spark sources. Do not pour
petrol into the fuel tank while the
engine is running and turn off the
engine of the generator and allow
it to cool down before adding petrol!
y Petrol is damaging to health. Therefore, prevent petrol
from coming into contact with skin, breathing in its
vapours and ingesting it. When handling petrol, use pro-
tective aids, i.e. waterproof gloves as well as
safety glasses. Petrol is absorbed through
the skin into the body. Only add petrol in
well-ventilated environments to prevent
inhalation of fumes.

ATTENTION
y Norm ČSN 65 6500 stipulates that unless fuel is sto-
red in an enclosed air-tight, light-proof container at
a temperature of 10-20°C, the recommended period
for which the petrol is usable is 3 months.
Petrol deteriorates, meaning that the most volatile
(flammable) components evaporate from the petrol and,
likewise, when ambient temperatures fluctuate petrol
may be contaminated by condensating air moisture,
which based on the age of the petrol may result in pro-
blems with starting the engine, reduced power, increase
carbonisation of the spark plug, exhaust pipe, etc.
We recommend adding a petrol conditioner to
the petrol (petrol dewatering fluid). It helps
a great deal in the event of problems with
starting, improves the characteristics of the pet-
rol, extends the lifespan of the engine and reduces carbo-
nisation of the exhaust pipe. Petrol conditioner can be
purchased at fuel stations. Based on our experience, a pro-
ven conditioner is from the Wynn' s brand under the name
DRY FUEL from the Belgian manufacturer. When using the
conditioner, follow the instructions for its use that are pro-
vided on the packaging of the product. Based on our ex-
perience, it is sufficient to add a smaller amount of conditi-
oner to the petrol than specified by the manufacturer,
however it also depends on the quality and age of the pet-
rol, since the petrol may be deteriorated already when sold
at the fuel station. Prior to using the petrol, allow the con-
ditioner to act in the petrol for 15-30 minutes. In the event
that the conditioner is added directly into the fuel tank of
the pressure washer, it is necessary to stir the blend by
appropriately moving the pressure washer, to enable the
