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.
6.2. 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 autostop 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.
6.3. 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.
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.
