Intended use
This waste water pump must not be operated in en-
closed spaces and is only approved for outdoor opera-
tion.
This waste water pump is not approved for use in the
food industry.

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.
