Translation of the Original Operating Instructions
7.1. Oil change and oil level check
When using models with auto-lubrication, please check the oil level prior to each use.
Every 100 operating hours or at least once a year and after the first 20 operating hours an oil change must be
performed. On models with auto-lubrication, an oil change should be carried out at least once per year. During
this period of time, the quality of the motor oil will clearly drop even if the device is used only infrequently. To carry
out such an oil change, please drain the old oil and fill in new oil through the filling opening into the oil reservoir.
Quickly turn the engine several times in the running direction, in order to distribute the oil evenly.
Meticulous maintenance and care should include the check of the oil level prior to each use. To carry out this
check, please use the dipstick provided. During the check the unit has to stand level and must be switched off and
cooled down. Please make absolutely sure that the oil level is within the indicated minimum and maximum limits.
Please observe the local regulations regarding the disposal of waste oil.
7.2. Automatic activation of the low-oil auto-stop feature
The pump is equipped with a low-oil safety feature. The models with auto-lubrication are equipped with an auto-
stop feature. This handy feature will automatically cut out the engine in case the motor oil level drops below the
required minimum. In this case starting the motor again is impossible until a sufficient quantity of motor oil has
been topped up. When topping up motor oil, please observe all information contained in this manual regarding
motor oil and oil level check.
7.3. Spark plug
Cleaning the spark plug and, where necessary, an adjustment of the electrode gaps should be performed at
intervals of six months or 100 hours of operation. To perform maintenance on the spark plug, please pull off the
spark plug socket first. Then use a spark plug wrench to remove the spark plug. For a disturbance-free
functioning the spark plug has to be dry and free of combustion residues, and the electrode gap must be between
0.6-0.7 mm.
If required, please clean the spark plug. We recommend to use a fine-wire brush to remove combustion residues.
Where needed, correct the electrode gap by carefully bending the electrode. In the case of excessive deposits or
worn electrodes you should insert a new spark plug.
Manually screw in the inspector, clean or, possibly, new spark plug until it comes to a stop. Then tighten the spark
plug carefully using the spark plug wrench. Please do not use excessive force in order to avoid overtightening and
consequently damaging the spark plug. To complete your work, slip the spark plug connector on the spark plug.
7.4. Air filter
For reason of the fire or explosion hazard involved, please do never use petrol or solvents with
a low flashpoint to clean the air filter.
A dirty air filter means that the airflow into the carburetor is inhibited. To avoid operational malfunction of the
carburettor, the air filter has to be checked regularly and cleaned or replaced, if necessary.
Basically, checking the air filter for contamination is recommended prior to each use. Cleaning should be
performed at the latest every three months or after 50 hours of operation, respectively. If the device is used in a
very dirty or dusty environment, it is advisable to shorten the cleaning intervals, for instance down to 10 hours. A
new air filter should be installed every six months or after 300 hours of operation, respectively.
To perform this maintenance work, please open the air filter box and take the filter out. If necessary, wash out the
air filter in a non-combustible solvent such as a washing-up liquid (dishwashing detergent). For reason of the fire
or explosion hazard involved, please do never use petrol or solvents with a low flashpoint to clean the air filter.
After cleaning, please allow the air filter to dry.
Insert the checked, cleaned or new air filter in the air filter box and close the box again.
The pump must never be operated without an air filter since this would increase the wear and tear of the engine.
7.5. Replacing the mechanical shaft seal
The mechanical shaft seal is used to seal the pump body from the motor shaft. It counts among the parts which
are subject to natural wear and tear.
If the mechanical shaft seal is defective, water will escape between the engine and the pump body. Qualified
persons should only carry out replacement of the mechanical shaft seal.
7.6. Removing foreign matters from the pump
Coarsely sized particles contained in the liquid being discharged may entail the clogging of the pump body and
pump wheel. In this case, it is possible to detach the pump housing in order to free the pump body and the pump
wheel from the solid matter.
7.7. Transport and storage
In order to avoid the risk of fire, allow the motor to cool down before transporting or putting it in
storage.
During transport, the water pump fuel valve should be set to OFF and the water pump kept
level, in order to avoid the fuel leaking out. Spilled petrol or petrol vapours can ignite.
