If the apparatus is not used for at least 3 months
or if frosts are expected in winter months, the
pump shall be properly protected against damage
caused by frost or against freezing. Prepare
proper solution for protection in winter months
according to the instruction on the protective
means. Pour the solution carefully into the inlet of
the apparatus. After the solution dripped away at
the outlet, close it with cork or another suitable
plug or closing device. Place into the inlet so
much non-freezing liquid till the pump is full. Then
close the inlet with cork or another suitable plug.
Before using the apparatus after treatment with
protective non-freezing liquid all liquid shall be
discharged from the pump, hose and water piping
leading to the jet. After first restarting the
apparatus again a bit of liquid may pour out from
the pump. This pouring will stop shortly.
Installation
Remove all packing material from the apparatus.
Check the apparatus, all parts and accessories
and make sure that no part is missing and that no
damage occurred during the transportation.
Setting on the Handle and Guides (Fig. 6)
Fix the handle and the device for placing
accessories to the frame of the apparatus. Stick
the lock screws through the holes outside the
apparatus and fix them with securing collar.
Tighten manually. Fix the hook for high-pressure
hose and guides to the upper handle.
Wheel Installation (Fig. 3)
Before fixing the wheel loose the screw and
release the axis. Set the wheel on the axis and
secure it with delivered locking nut.
Pump Plug (Fig. 10)
Observe the rules of your water company.
According to the EN 61 770 standard, the
appliance must not be immediately connected to
public drinking water supply. However, short-term
connection is according to DVGW (German
Association of Gas and Water Branch) accepted
if there is a backflow barrier with air intake inbuilt
in the supply line. Also mediated connection to
public drinking water supply through free output
according to EN 61 770 is allowed; e.g. by
inserting a container with a float valve. Immediate
connection to the line network not designed for
distribution of drinking water is admissible.
The apparatus is furnished with the plug
preventing leakage of the oil during
transportation. Remove the transport plug and
60

12
replace it with the plug with bleeding function that
is included in the delivery. The pump of the
apparatus has closed oil circulation that needs no
maintenance. (Refuelling or exchange of oil is not
necessary).
Before Putting into Operation
Following operations shall be performed before
putting the apparatus into operation:
•pour the engine oil into gearbox
•pour the petrol into the tank
•connect the high-pressure hose to the
spray gun and to the pump
•connect the pump to the water main
•connect the jet to the spray gun
Important Warning: The engine and the pump
of your apparatus needs some period of time
to run in. Therefore the apparatus will operate
with full output after a few hours of operation.
Pouring the Engine Oil into Gearbox (Fig. 12)
Never try to start the apparatus if there is not
enough corresponding oil in the engine. There is
no oil in the apparatus at delivery thereof. If the
apparatus operates without (sufficient quantity of)
engine oil, the engine will get damaged. Place
the apparatus on flat surface and remove the
cover from the oil tank. Fill the engine oil at least
up to the half of the measuring bar length.
Pouring the Petrol into the Tank (Fig. 2)
High-pressure cleaner is driven by a 4-stroke
engine requiring leadless petrol. Use suitable
funnel for filling up the petrol. Make sure there is
not too much petrol in the tank and prevent
spraying the petrol out. The oil should reach up to
the fuel filter, not higher.
Connection of High-Pressure Hose to the
Handle of the Gun and the Pump (Fig. 7)
Put the water pipe on the spray gun. Hold the
end of the gun and screw the pipe on it so that
the connection is firm and sure. Caution! Do not
tighten the screw too much, both supply
connections may be damaged.
The supply connection of the high-pressure hose
with the supply connection on the bottom side of
the spray gun handle connect firmly and safely.
Caution! Do not tighten the screw too much, both
supply connections may be damaged.
Safety Stop for High-Pressure Water Pipe
(Fig. 16)
The gun handle has a safety device preventing
unwanted activation of high-pressure pipe. This
device can be put into operation by leasing the
handle and activating safety stop between the
trigger and the handle.
Connection of the Hose (Fig. 13)
The water supply connection is furnished with
particle filter. Never let the apparatus work
without filter. The intervals for checking and
cleaning of the filters depend on the water
quality. If the water in the water mains contains
impurity articles, the filter shall be cleaned after
every use because otherwise the apparatus
output will (considerably) fall and the pump may
be damaged.
The supply connection part for water supply has
a form of a (male) plug and shall be fastened with
screw on the inlet to water tank of the apparatus.
Put the clamping element (female) to the hose
and then connect this element with the part of
supply connection in form of a plug. Connect the
high-pressure hose to the connection/discharge
for high-pressure. Release water and press the
handle in form of a gun till the water starts flowing
from the pipe continuously. The water
temperature shall not exceed 40 0 C..
Setting the Spraying Angle (Fig. 11)
Warning: The protection against spraying away
shall always be properly set, otherwise it could be
pushed in under the influence of the high-
pressure jet, and it may also cause injury and
damage.
You may chose from 4 different jets market by
your colour that may show various spraying
angles.
0° jet (red):
This jet creates an extremely focused jet with
very high pressure force. It is suitable for
particularly careful cleaning of small areas. The
jet is therefore applicable only on the areas that
can resist such a pressure, e.g. metal or
concrete. Not suitable for wood.
15° jet (yellow):
This jet creates a jet 15° wide, therefore it is
especially suitable for intensive cleaning of
smaller areas. The jet can be used only for areas
that can resist such high pressure.
40° jet (white):
The jet creates a jet 40° wide, water pressure is
medium strong. This jet is suitable for cleaning
larger areas and may be used for most cleaning
works.
Low-Pressure Jet (black):
This jet can be used for chemicals and cleaning
agent’s application. It creates the lowest
pressure.
Important warning: The high-pressure jet can
damage the lining, coating and pavement due
to the type of m aterial or insufficient know-
how. Therefore check first the effect on a
smaller area. If nece ssary the water pressure
can be ch anged by replacement of the jet or
by reduction of the engine output.
61

13
Connection of the Jet (Fig. 15)
Connect the jet with quick-coupling device to the
water pipe leading to the jet. By means of the
quick-coupling the jets can be replaced quickly
and without any problems. After the jet is
connected, shift the safety collar back towards
the gun, then set the jet on the end of water pipe.
Release the safety collar. The jet is firmly set in
the required position. When replacing the jet shift
the safety collar back, remove the old jet and set
the new one.
Caution: Check always carefully if the jet has
been set correctly.
Caution: If the safety collar cannot be s hifted
back without problems, the je t has no t been
correctly set. Press the jet with strength into
the corresponding hole, bec ause the safety
collar will not return back by itself and the jet
will get out.
Cleaning Means (Fig. 8)
Use suitable tank with cleaning means
determined for pressure washing machines. Do
not use rinsing means for washing, they contain
salt. Quality cleaning means for pressure
washing machines are recommended for this
high-pressure cleaner. Observe the instructions
on the vessel/canister. Most washing means for
cars contain combination of washing means and
wax for chassis (wax-washing means mixture).
They are mostly dense, viscous means. The
viscosity (hence liquid density) of the cleaning
means usually increases in cold weather. We
recommend to solve this kind of washing means
in hot water before pouring it into the vessel. At
combination of washing and wax means it is
recommended to prepare a solution before use.
As basic principle the ratio of the mixture 50:50 is
recommended. Of course, you can create a
mixture with a different ration based on testing,
that may be more suitable for your purposes.
Instructions:
•Dense cleaning means cannot flow
properly from the cleaning vessel and
it can clog the system with deposits.
•The cleaning vessel shall be
thoroughly rinsed with water after
use.
When using the delivered cleaning means the
black jet (low pressure) shall be fixed on the end
of the water pipe. Insert the end of the suction
pipe into the cleaning means vessel of the high-
pressure cleaner. Suction and mixing of the
cleaning means will pass automatically if the
water flows through the pump.
Installation of High-Pressure Cleaner
•Place the high-pressure cleaner on solid
and even surface in a way enabling
properly lubrication of the engine and the
pump. When installing avoid the places
with depressions or holes (e.g. places
with puddles). When the surfaces are
smooth and slippery, there is danger of
injury!
•Place the apparatus on a well ventilated
place in sufficiently safe distance from
inflammable materials or vapours. Safety
regulations for proper ventilation shall be
principally observed. Minimum distance
from inflammable materials shall be 50
cm.
•The apparatus shall be placed so that the
operator will have easy access to all
parts thereof and to the control elements.
During installation the apparatus shall be
properly protected against the damages
from outside.
•The high-pressure hose shall not be laid
across the traffic area, otherwise it may
be worn very quickly and damages may
occur.
Putting the Apparatus into
Operation
•Remove dirt and foreign particles from
the spray gun and from the connection in
form of a plug.
•Put the jet on the spray gun.
•Start the engine
Warning: The protection against spraying
away shall all the time be properly set,
otherwise it could be d epressed by high-
pressure jet, and damage and injur y may
occur.
Start of the engine: (Fig. 14/20/17/21)
•Turn the petrol cock (ON)
•Open the choke (ON)
•Set the engine switch on EIN/ON
•Hold firmly the engine on the frame with
one hand. Hold the starter cord with the
other hand and pull it slowly until you feel
the resistance and the starting element
reaches the required position. When you
feel the resistance, pull the cord strongly
and quickly. Repeat this procedure till the
engine starts.
•If the engine has been put into running
and runs evenly, put the choke lever on
OFF (deactivation).
•The number of revolutions of running
engine may be modified with gas lever.
By shifting the lever to the right, the
number of revolutions will drop, by
shifting it to the left the number of
revolutions will increase.
•Switch off the engine by putting the
engine switch to position AUS/OFF.
