The pump must not be operated permanently in the absence of water. This so - called dry running -
i.e. the operation of the pump without any water being discharged - may cause considerable
damage to the unit because the required cooling is missing. If necessary, you have to stop the
engine, check the intake line and the connection ports for leakages and refill the pump body and
possibly the intake hose, too, with water.
The petrol engine pump must not run with the withdrawal point being shut off. Do not let the pump
“work” against a closed pressure side.
Please do not top up fuel or motor oil with the engine running. For fuelling, please switch the pump
off and allow at least five minutes for it to cool down. During fuelling, and also during operation or
as long as the device is switched off, please make sure that it is standing upright on a level surface
in order to prevent any spilling or leaking of fuel.
Do not touch the exhaust pipe and its cover during operation since these parts become very hot
and bear the hazard of burning. Even after the device has been switched off, these parts remain
very hot and must only be touched after allowing for an appropriate period of four cooling down.
Other parts of the engine, too, become hot during operation. Therefore, please avoid to touch the
unit during operation and afterwards from power - off to its cooling down at any points other than
those intended for this purpose, e.g. at the control switches and levers or the handles.
Combustible or easily inflammable or explosive matters and objects are to be kept out of the area
of the pump while in operation. Please do not place any objects on top of the engine.
5.7. To stop the engine
Put the throttle control to the idle position, then the ignition breaker to “OFF”.
The pump inlet is equipped with a valve which will prevent the water from escaping out of the
pump housing after the pump was switched off. This return stop will shorten the required priming
period at the next start. Moreover, in this way it is not necessary to fill the pump housing with water
at the next start of the pump.
5.8. Ending the application
The pump must not be transported with its fuel tank filled.
After each use, please drain the water contained in the pump through the opening provided for this
purpose. Allow the pump body to dry well to avoid possible damage by corrosion. In the case of
frost, water remaining inside the pump may freeze up and thus cause considerable damage.
If the device is transported after having been in use, the fuel has to be drained completely.
Transporting the pump with its fuel tank filled is not allowed.
