oil level (see chapter Filling oil , illustration Y1 )! If the oil level is correct, insert the
dipstick again and tighten it.
Cleaning and replacing the air filter (Illustration W )
IMPORTANT
Never let the engine start or run whilst the air filter is removed.
– Open the cover (1), pull down and out and remove.
– Remove the paper filter insert (2) and pre-filter (3). To remove the pre-filter from
the cover, remove the grid (4) first.
– Clean the paper filter insert every 50 operating hours
Knock gently onto a smooth surface if soiled lightly. Replace if heavily soiled or
damaged. Do not wash out paper filters, nor blow them out with compressed air or
grease them.
– Clean the pre-filter every 50 operating hours.
Wash pre-filters in hot water with liquid detergent, rinse them out in clean water,
press out excess water and allow to dry thoroughly in air. Do not lubricate the pre-
filter with oil.
– After cleaning or replacement, insert the filter element into the air filter plate, insert
the pre-filter in the cover and fix in place with the grid.
– Insert the hooks (5) on the cover (1) into the seat (6) at the bottom in the air filter
plate.
– Tilt the cover upwards and close with care.
In the case of unfavourable operation conditions (severe formation of dust), cleaning is
required after every mowing process. Replace the paper filter element and pre-filter
annually or every 100 operation hours.
(Please see original spare parts and accessories for order no. of filter element)
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 0.6-0.7
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.
Correct winter storage of the engine (or when not used for a long period
of time)
– Empty the petrol tank or allow the engine to run until it stops due to lack of fuel.
– Switch off engine and disconnect spark plug cable.
– Drain off the oil while the engine is still warm. Fill with fresh oil (for quantity and
type, see technical data).
– Clean grass and chaff from cylinder and cylinder head fins and around muffler.
– Always keep the machine in a clean condition in a closed, dry room out of reach of
children.
