– Loosen the nut (1) on the air filter cover (2) and remove the cover.
– Remove the pre-filter (3) and paper filter element (4).
– Clean the paper filter element every 50 operating hours.
If slightly dirty, knock the dirt off; if very dirty or damaged, replace it. Do not blast out the paper filter using compressed
air. Do not grease it.
– Clean the pre-filter every 50 operational hours.
Wash the pre-filter in hot water with liquid detergent, rinse it out, press out excess water and allow it to dry thoroughly in
air. Do not lubricate the pre-filter with oil.
– Insert the dry pre-filter on the paper filter element and fit both in the air filter plate (5). Ensure that the air filter sits firmly
in the plate.
– Put the cover (2) on the air filter and fasten it with the nut (1) on the air filter plate (5).
In the case of unfavorable operation conditions (severe formation of dust), cleaning is required after every mowing process.
Replace the paper filter element and pre-filter annually or every 200 operation hours.
(Please see original spare parts and accessories for Order No. of filter element and pre-filter)

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 0.5-0.6 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.
