Cleaning and replacing the air filter (Illustration W )
IMPORTANT
Never let the engine start or run whilst the air filter is removed.
– Loosen the nut (1) on the air filter cover (2) and remove the cover.
– Remove the fastening nut (3) and remove the filter (4). Remove the pre-filter (5) from the paper filter element.
– Clean the paper filter element every 25 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 25 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 on the stud bolt (6) and air filter plate (7). Pay attention to
ensure that the filter engages safely with the filter plate. Fasten the filter with the nut (3).
– Put the cover (2) on the air filter and fasten it with the nut (1) on the air filter plate (7).
In the case of unfavorable operation conditions (severe formation of dust), cleaning is required after every scarifying
procedure. Replace the paper filter element and pre-filter annually.
(Please see original spare parts and accessories for Order No. of filter element and pre-filter)
Checking the spark plug (Illustration Y )
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 0.76 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 sparkplug. Close the fuel cock
Y2 .
– Drain the oil so long as the engine is still hot. Fill in fresh oil (for quantity and quality, see technical data).
– Remove grass and mowing deposits from the cylinder and cylinder ribs, under the engine hood and around the silencer.
– Always keep the equipment in a clean state in a closed, dry room and inaccessible to children.
