MIXING THE FUEL MIX
y When filling up the fuel tank of a pump that
has never been operated, mix the fuel and oil at
a petrol:oil ratio of 35:1, for example in the supplied
plastic measuring bottle with volume scale. After
adding oil to the petrol, thoroughly stir up the prepa-
red mix to ensure that the oil does not sit at the bottom
of the measuring bottle.
When illing the fuel tank of a pump that has already
been in operation, prepare a petrol:oil mix of 40:1.
In the table provided below, this ratio is calculated for
mixing several litres of fuel mix.
Petrol:oil ratio of 35:1 for the irst ill up of the fuel
tank:
Mix 1 litre of petrol with 29 ml of two-stroke oil.

FILLING UP WITH FUEL
y Fuels are poisonous. Therefore, prevent these sub-
stances from coming into contact with skin and do not
digest them. When handling fuels, use protective aids,
i.e. gloves and protective glasses. Petrol is absorbed
through the skin into the body. Fill the fuel tank in well
ventilated locations. Avoid breathing in the vapours.
They are harmful to health.
y Fuels are flammable and ignite easily, therefore, do
not smoke when handling fuels or use an open flame
or sources of sparks. Do not refill fuel in the presence
of radiant heat sources and while the pump motor is
running. Turn off the motor and allow it to cool down
before refilling it.

1. Screw off the fuel tank cap and through the
fuel tank strainer pour in the mix prepared in
the above-described manner.
y On model 414503, the strainer is inserted inside the
neck of the fuel tank.
y With model 414502 it is necessary to pour fuel into
the fuel tank using a funnel fitted with a strainer.
The strainer will remove any potential mechanical
particles contained in the fuel, which could clog the
pump's fuel system. Do not overfill the fuel tank to
prevent fuel from spilling out of the fuel tank when
handling the pump.
2. Firmly tighten the fuel tank cap after refilling
of fuel.
y If any fuel was spilled, wipe it away before starting
the motor.
V. Starting the pump's
motor
y The pump must not be operated in enclosed
5
rooms, in rooms with exhaust fume extraction
ducts not approved by relevant safety autho-
rities, or in areas with poor fume extraction,
e.g. outdoor trenches, where fumes remain at
ground level and are not removed efficiently.
The pump must not be operated in an environ-
ment with an explosion hazard.

ATTENTION
y Before starting up the pump's motor, place the pump
on a stable and even surface and ensure that the pump
housing is primed with water, that the suction hose is
submerged in water and the delivery hose is located
in its intended location. Secure the end of the delivery
hose before starting the pump to ensure that it is not
lash out as a result of the pressure impulse.
y Ensure that flow is unimpeded along the entire length
of the suction and delivery hose, i.e. by a kink, etc. In
the event that the hose is in contact with sharp edges,
place suitable protection between the hose and the
sharp edge at the contact point.
y Check that all connections are properly attached and secured.
1) Set the flow regulation lever (fig. 1A, position
8, fig. 2A, position 14) to approximately half
the maximum. The position of the flow regula-
tion lever for minimum and maximum speed is
the same for both models.

2) On model 414502, use a finger to press the fuel
priming pump 2x to 3x (fig. 1B, position 11).
y Do not unnecessarily press the primer pump more
times so as not to flood the carburettor with fuel.
M odel 414503 is not equipped with a fuel
priming pump, however it is necessary to
open the fuel supply to the carburettor by
turning the fuel valve (fig. 2A, position 9)
from the horizontal position (from position
„OFF") downwards to the vertical position
(position „ON").
3) Set the chock lever (fig. 1A, position 7, fig. 2A,
position 10) to position „CLOSE" – upwards to
the position of symbol
4) Hold the pump by the handle and step on the
part of the stand on the side of the manual
starter and pull on the pull cord of the manual
starter.
Then irmly pull on the starter handle and
slowly bring it back with your hand.

y Do not allow it to rewind in uncontrollably on its
own as this could damage the starting mechanism.
If the motor does not start up, repeat the move-
ment. If you are unable to start the motor, proceed
for min. and max.
according to chapter Cleaning and maintenance.
5) If the motor shows signs of starting up but is
choked, try setting the choke lever to position
„OPEN" - downwards to the position of symbol
. If not, leave the choke lever in the position
„CLOSE". Needs to be checked with a practical
test. After starting the motor, after a while,
gently move the choke lever to the position
„OPEN"
.
6) Set the power/rpm regulator to the position
between minimum and maximum - depending
on the required flow rate respecting the deli-
very height and suction depth, see fig. 5.
STARTING A WARM ENGINE
y When starting an already warm motor, on model
.
414502 it is not necessary to inject fuel into the carbu-
rettor using the priming pump. Likewise, it usually not
necessary to set the choke lever to the position „CLOSE",
however, it is necessary to make a practical test.
