6. Operation
The pump must be
fi
lled with the transport
fl
uid at
the
fi
ller neck (Figure 3 / Item 2) before the engine
is started.
Note: We advise that you install a non-return valve
in the intake line and
fi
ll it with water before you
start the machine for the
fi
rst time.
6.1 Starting the engine
1. Set the On/O
ff
switch (Figure 1 / Item 6) to
“ON”.
2. Set the petrol cock (Figure 4 / Item 8) to the
“ON” position.
3. If the engine is cold, set the choke lever (Fi-
gure 4 / Item 9) to “Choke”.
4. Move the throttle lever (Figure 4 / Item 10) to
the center position.
5. Pull the starter cord (Figure 4 / Item 7) until
the engine starts.
6. When the engine has been running for ap-
prox. 30 seconds, move the choke lever to
“Run”.
If the engine is warm, leave the choke lever in the
“Run” position when starting.

6.2 Intake process
•
During the priming process, the shut-off
devices present in the pressure pipe (spray
nozzles, valves etc.) must be completely
open so that the air in the suction pipe can
escape freely.
•
Depending on the suction height and the air
quantity in the suction pipe, the initial priming
process can last for approx. 0.5 min. – 5 min.
In the case of longer priming periods, top up
again with water.
•
If the pump is removed after use, it is essen-
tial that it is filled with water again the next
time it is connected and started.
6.3 Stopping the engine
•
Set the On/Off switch to “OFF”.
•
Close the petrol cock.
Running-in period:
For the
fi
rst 20 hours of operation, the motor must
not be operated at full throttle for too long.

culties:
Check whether
•
fuel is flowing into the carburetor;
•
the fuel filter is clean;
•
the carburetor air valve is open;
•
the air filter is clean;

the spark plug is clean and the electrode gap
is between 0.6 and 0.7mm.
7. Cleaning, maintenance, storage
and ordering of spare parts
Disconnect the spark plug boot before doing any
cleaning and maintenance work!
7.1 Cleaning
•
Keep all safety devices, air vents and the
motor housing free of dirt and dust as far as
possible. Wipe the equipment with a clean
cloth or blow it with compressed air at low
pressure.
•
We recommend that you clean the device im-
mediately each time you have finished using
it.
•
Clean the equipment regularly with a moist
cloth and some soft soap. Do not use
cleaning agents or solvents; these could
attack the plastic parts of the equipment. En-
sure that no water can seep into the device.
7.2 Maintenance
In this connection, please also read the attached
service information
7.2.1 Changing the oil
The engine oil is best changed when the engine
is at working temperature
•
Use only engine oil (10W40).
•
Place the machine on a slightly inclined sur-
face so that the oil drain plug is at the lower
end (Figure 5a / Item A).
•
Remove the oil filler screw (Figure 5a / Item
B).
•
Remove the oil drain plug and drain the warm
engine oil into a suitable container.
