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.
6.7.
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.
6.8.
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.
7. Maintenance and troubleshooting
If possible, please stop the engine, pull off the spark plug socket, and allow the engine to cool
down prior to performing any maintenance work. If it is necessary to keep the motor running
for performing certain maintenance work, please ensure sufficient ventilation because the
exhaust gases are toxic.
Regular maintenance and thorough care will reduce the risk of possible operational malfunction and contribute to
extend the life cycle of the unit. The technical design of engines is very complex, and they contain a huge number
of moving parts which are subject to high mechanical, thermal and chemical influences from the side of the
environment and the combustion process. The use of proper, high-quality and fresh operating fluids - fuel and
motor oil - will prevent both damage to the engine and downtimes.
Abrasive matters contained in the liquid being discharged - such as sand - accelerate wear and tear and reduce
the performance of the pump. When discharging liquids containing such matters, the installation of a prefilter is
recommended. This useful accessory it will efficiently filter sand and similar particles out of the liquids, thus
minimize wear and tear and extend the lifetime of the pump.
