ATTENTION
When tilting the machine upwards, ensure that no oil or fuel comes out of the
machine. Fire hazard!
The regular implementation of the prescribed maintenance and care work are the
prerequisite for a permanent and fault-free functionality of the motor and also the basic
requirement for any guarantee claims.
The motor should be kept clean, particularly on the outside, and the silencer and
cylinder area must always be kept free from foreign bodies (e.g. grass residue). The
exhaust and motor reach very high temperatures when in use. Flammable foreign
bodies such as foliage, grass etc. may catch fire.
Perfect cooling can also only ensured when cylinder ribs are always clean.
IMPORTANT
Never use a pressure cleaner or ordinary water jet to clean the motor. Damages
or expensive repairs can be the consequence of such action.
Oil change
Check the oil level before every use and replenish oil if necessary (see "Check oil
level" and "Fill with oil", illustration Y1 ).
An oil change is not necessary. If you wish to change the oil, however, please follow the
instructions below.
NOTE
For environmental reasons, we recommend that the oil change is performed by
an authorised workshop.
Changing the oil
– Before the engine or the equipment is tilted to drain oil, empty the petrol tank and
let the engine to run until it stops due to lack of fuel.
– Stop the engine and remove the spark plug connector.
– Renew the oil as long as the engine is warm.
– To change the oil, remove the dipstick from the oil refill neck.
– Turn the mower on one side so that the spark plug side is facing upwards and the
used oil can drain into a container.
Do not drain used oil into the sewage system or soil; dispose of it according
to the local regulations.
– Position the mower straight and fill brand-name oil into the spout (for quantity and
quality, see technical data). Screw the dipstick in and check the oil level (see
"Check oil level" and "Fill with oil", illustration Y1 )! If the oil level is correct,
insert the dipstick 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.
47-VARIO, 47-VARIO E
– 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.
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.
– 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 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 200 operation hours.
(Please see original spare parts and accessories for Order No. of filter element and pre-
filter)
47-ECONOMY, 47-A ECONOMY
– Open the cover (1), pull down and out and remove.
– Remove the filter element (2) carefully and knock gently onto a smooth surface if
soiled. Replace if heavily soiled or damaged.
– Never lubricate the insert with oil or blow it with compressed air. Severely dirty or
oily filter elements must be replaced.
– After cleaning or replacement, insert the filter element into the air filter plate.
– Insert the hooks (3) on the cover (1) into the seat (4) at the bottom in the air filter
plate.
– Tilt the cover upwards and close with care.
In the case of unfavourable conditions (heavy dust development), the mower must be
cleaned every time it is used, otherwise after 25 operating hours or every year.
(Please see original spare parts and accessories for order no. of filter element)
Checking the spark plug (Illustration Y )
47-VARIO, 47-VARIO E
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 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.
47-ECONOMY, 47-A ECONOMY
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 0.7-0.8
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.
All models
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.
