The first oil change of a new engine is necessary after 5 operating hours, and thereafter every 50 hours of operation or at
least once per mowing season.
– Before the engine or whole device is tipped to drain the oil off, empty the petrol tank and allow the engine to run until it
stops due to lack of fuel.
– Switch off the engine and disconnect the spark plug cable.
– Change the oil with the engine still warm.
– To change the oil, remove the dipstick from the filler and lay the mower on its side so that the used oil drains into the
catch tray.
Old oil should be disposed off in accordance with the relevant local regulations and on no account be
discharged into the sewerage system or into the ground.
– Turn the mower upright and pour high quality oil (for quantity and type, see technical data) into the filler. Screw on
dipstick and check oil (see Chapter Filling with oil, illustration Y1 )!

To check for wear, remove the spark plug connector and unscrew the spark plug. If the electrode is badly worn the spark
plug must be replaced as a matter of course. (Order no. see original spare parts list and accessories).
Otherwise it is sufficient to clean the spark plug and set the electrode gap to 0.7 mm. Screw the spark plug (pay attention to
sealing ring) into the engine by hand and tighten using the socket wrench. Press on spark plug connector. Replace the spark
plug annually.
