•
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.
Warning: After switching off the engine stop water supply
and release the residual pressure by pressing of gun
handle till no pressure remains in the apparatus and the
water stops flowing out. Then secure the spray gun with
safety stop, protecting it against unwanted switching on.
Remove the water pipe leading to spray jet and discharge
the remaining water from all hose parts. Roll up carefully
the hoses, no bends or depressions are permitted. When
doing so, check if the hose elements are not damaged,
replace the damaged parts if necessary. Faulty hoses can
be very dangerous when under pressure!

Before storing the switched off engine close the
petrol cock (OFF)
Trouble Shooting
(
Problem):
Alternating Pressure
(Cause):
1.
The pump intakes the air, dirty, worn
or blocked valves
2.
Clogged jet
(Measure):
1.
Check the tightness of all supplying
connections
2.
Remove the deposits with jet
cleaner
(Problem):
Water is flowing out of the
pump
(Cause):
1.
Worn sealing
(Measure):
1.
Contact customer service
(Problem):
Pump does not reach the necessary
pressure
(Cause):
1.
The pump intakes the air at the
supply connections or at the hose
2.
Clogged suction or discharge valves
3.
Blocked discharge valve
4.
Worn water pipe or jet
(Measure):
1.
Check the tightness of all supply
connections
2.
Clean or replace the valves, have
apparatus checked by customer
service
3. Loosen or tighten with the
set screw.
3.
Check and/or replace
(Problem):
The pump runs but does not
pump the water
(Cause):
1.
Inlet or pressure hose are clogged
or blocked
2.
Suction filter is clogged
3.
The jet is clogged
(Measure):
Cleaning and Maintenance
Remove Clogging (Fig. 22)
Warning: Switch off the engine and let it get cold before
checking, cleaning, maintenance or replacement. The
pressure shall be completely reduced. If the effect of water jet
is permanently changing and water does not flow regularly,
release the trigger and switch off the apparatus. When the
apparatus is switched off, press the trigger and discharge the
residual pressure. Check the jet at the end of the water pipe if
t is not clogged. If you suspect that there are some deposits
inside, remove them with special cleaner. The water jet shall
be checked regularly and maintain in good condition by jet
cleaner that is involved in the delivery. Before performing
these works the engine shall be principally switched off and
the apparatus disconnected from the water supply
Regular Maintenance
Spark Plug (Fig. 9)
Check the spark plug every 50 hours of operation. Check the
colour of deposits on the end of the plug. The colour should
be „slightly brown-row brown". Remove the deposits with wire
brush. Check the distance of electrodes on the spark plug and
set the correct 0.7-0.8 mm distance, if necessary.
Refilling/exchange of Engine Oil (Fig. 19)
The first exchange of engine oil is recommended after 40
operation hours, then after every 100 hours.
•
Place the apparatus on even surface and let the
engine getting hot for a few minutes.
•
Then stop the engine.
•
Place a suitable vessel under the pump for catching
the old oil.
•
Remove the cover from the oil tank, remove the
discharge screw and sealing so that the oil may be
completely discharged. Use the pipe or another aid
preventing creation of stains on the frame of the
apparatus by discharging oil.
•
Check the discharge oil screw, sealing, closing
device on oil inlet and O-ring. Replace if necessary.
•
Set again the oil discharging screw and sealing.
Tighten the oil discharge well and firmly.
•
Refill the oil at least up to the half of the gauge
•
Fix again firmly and securely the oil inlet closing
device.
The waste oil shall be removed according to the principles of
environment protection. In many cases the waste oil can be
delivered to your pump station. Never dispose of the oil
together with domestic refuse and do not discharge it into the
soil!
Air Filter (Fig. 23)
Remove the air filter and check if it does not contain
impurities or is not damaged and clean it every 100 operation
hours or once in a month. Clean the filter thoroughly with
cleaning means on water basis that is not harmful for the
environment and has degreasing effect. Let the air filter get
dry well and put it back again.
Warning! Never let the engine on without air filter!
Oil Vessel Filter (Fig. 18)
The oil vessel filter shall be removed and cleaned always
after 150 operation hours or every 3 months. In this case
remove the closing device from the oil vessel and thoroughly
clean the filter with cleaning means on water basis that is not
detrimental for the environment. Then put the filter back and
put the closing device back.

Check, repair or replace, if
necessary
2.
