– Place the mower to the side so that the spark plug side is at the top and the waste
oil is drained into a collecting vessel.
Do not drain used oil into the sewage system or soil; dispose of it according
to the local regulations.
– Put up the mower and fill in brand oil at the connector (for quantity and quality refer to
the technical data). Screw in the dipstick and check the oil level (see “Checking the
oil level” and “Filling with oil” , figure Y1 )! If the oil level is correct, insert the
dipstick and tighten it.
Cleaning and replacing the air filter (figure W )
IMPORTANT
Never let the engine start or run whilst the air filter is removed.
– Loosen the air filter cover lock (4) with a screwdriver from the air filter housing (1)
and remove the air filter cover (3).
– Remove the filter(s) (2).
– Clean the filter(s) every 50 operational hours.
In case of minor contamination, tap out gently on a smooth surface. In case of severe
contamination or damage, renew the filter(s). Do not wash out or blast out the paper
filter using compressed air and do not oil it.
– Insert the filter(s) (2).
– Attach the air filter cover (3) onto the filter and let the air filter cover lock (4) engage
in the air filter housing (1).
In the case of unfavourable operation conditions (severe formation of dust), cleaning is
required after every mowing job. Replace the air filter annually or every 200 operating
hours.
(For the air filter order number, refer to original spare parts and accessories)
Checking the spark plug (figure Y )
To check for wear, remove the spark plug connector and screw out the spark plug. If the
electrode is badly worn, the spark plug must be replaced as a matter of course (for order
no. see original spare parts list and accessories).
Otherwise it is sufficient to clean the spark plug with a steel brush and set the electrode
gap to between 0.7 and 0.8 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.
Correct winter storage of the engine (or when not used for a long period
of time)
– Empty the petrol tank and let the engine run until it stops due to lack of fuel.
– Stop the engine and remove the spark plug connector.
– Drain the oil as long as the engine is still warm. Fill in fresh oil (for quantity and
quality refer to the technical data).
– Remove grass and mowing deposits from the cylinder and cylinder ribs, under the
engine cover and around the silencer.
– Always keep the device in a clean state in a closed, dry room and inaccessible to
children.
