Refuelling
1. Unscrew the fuel tank cap.
2. Fill fuel up a maximum of the lower edge of the filling
nozzle.
3. Fit the fuel tank cap and screw tight.
Positioning the pump
The delivery performance of the pump is heavily de-
pendent on the operating conditions. Adhering to the
following rules will ensure optimum performance.
Keep the height difference between the water sur-
face and the pump as small as possible.
Position the pump so that the suction hose is a short
as possible.
A long pressure hose is better than a long suction
hose.
Do not unnecessarily long hoses.
Connecting the hoses
1. Push the hose clip onto the suction hose.

2. Slide the union nut onto the hose nipple.
3. Push the suction hose onto the hose nipple.
4. Position and tighten the hose clip.
5. Fit a flat seal between the suction nozzle and hose
nipple.
Note:
A reinforced hose suitable for vacuum appli-
cations must be used for the suction hose.
6. Connect the suction hose to the suction nozzle and
tighten the union nut.
7. Fit the suction filter to the other end of the suction
hose.

8. Fit a hose nipple, union nut and hose clip to the
pressure hose (not included in the scope of deliv-
ery).
9. Fit a flat seal between the hose nipple and outlet.
10. Connect the pressure hose to the outlet and tighten
the union nut.
Operation
Venting the pump
ATTENTION
Risk of damage
The seals will be damaged if the pump runs dry.
Vent the pump before starting. If the pump is accidentally
run dry then stop the engine immediately and allow the
pump to cool down before starting the venting procedure.
1. Unscrew the cap from the filler opening.
2. Fill the pump completely with water.
3. Screw the cap back into the filler opening and tighten.
Starting the device
1. Vent air from the pump.
2. Open the fuel cock.
3. Push the choke lever to the left.
4. Push the accelerator lever to approximately 1/3 of
the total range.
5. Set the power switch to "I".
6. Pull the starter cord slowly until a strong resistance
is discernible then pull strongly.
7. Slowly return the starter cord.
ATTENTION
Risk of damage
A rapidly returning starter cord damages the device.
Slowly return the starter cord.
8. Push the choke lever to the right once the engine
has started.
9. Push the accelerator lever to the left until reaching
the desired speed. The flow rate of the pump de-
pends on the engine speed.
10. Check the function of the pump. Dry running damag-
es the pump. Switch off the engine and repeat vent-
ing of the pump if the pump does not deliver water.
Switching the device off in an emergency
1. Set the power switch to "0".
Switching off the device
1. Push the accelerator lever all the way to the right.
2. Set the power switch to "0".
3. Close the fuel cock.
Draining the water
1. Unscrew the water drain screw.
2. Allow the water to drain from the pump.
3. Unscrew the cap from the filler opening.
4. Flush the pump with fresh water.
5. Allow the fresh water to drain away.
6. Screw the cap into the filler opening and tighten.
7. Screw in and tighten the water drain screw.
Transport
Set the power switch to "0" before transport.
Allow the engine to cool down for at least
15 minutes before loading.
Keep the device horizontal during transport to pre-
vent fuel from spilling out.
When transporting in vehicles, secure the device
against rolling away, slipping and tipping according
to the respectively applicable guidelines.
Be aware of the weight of the device during trans-
port.
Storage
CAUTION
Failure to observe the weight
Risk of injury and damage
Be aware of the weight of the device during storage.
ATTENTION
Risk of damage
Do not place any heavy objects on the device.
Store the device in a dry and dust-free place.
Cleaning the device
The device must be cleaned before storage.
1. Allow the device to cool down for a half-hour if it was

2. Flush the pump with clear water.
3. Manually wash the exterior of the device with a
small amount of water.
4. Rub all accessible surfaces dry.
5. Unscrew the water drain screw and allow the water
to drain out.
6. Screw in and tighten the water drain screw.
7. Lightly oil rust-prone surfaces.
8. Spray the control elements with silicone spray.
Storage duration of 1...2 months
1. Add petrol stabiliser to the fuel tank.
2. Top up the fuel tank.
Storage duration of 2...12 months
