19 SERVICING THE ENGINE

WARNING
Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause serious illness or death.
Do not run an engine in an enclosed area, such as a garage, even with doors and windows open.
Move the machine to an outside area before starting the engine.
IMPORTANT
To clean the engine and for maintenance work, close the petrol tap Y2 , lay the mower on the right-hand side, or
even better, tip it forwards O (spark plug upwards) because otherwise there may be problems starting the engine.
When tipping the mower forwards, make sure that the ejection flap is not damaged. Secure the mower in the raised
position!
ATTENTION
When tilting or placing the mower on its side, 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

NOTE
For environmental reasons, we recommend that the oil change is performed by an authorised workshop.
GB
The first oil change of a new engine is necessary after 8 operating hours, and thereafter every 50 hours of operation or at
least once per mowing season.
– Let the engine run warm.
– Switch off the engine and disconnect the spark plug cable.
– Change the oil with the engine still warm.
– The oil can only be changed by extracting the old oil via the oil filler neck. Hand pumps are available in specialist stores.
Old oil should be disposed off in accordance with the relevant local regulations and on no account be
discharged into the sewerage system or into the ground.
– After removing the old oil, refill with fresh, clean quality oil (for quantity and type, see technical data). Insert the dipstick
and check oil (see Chapter Filling with oil, illustration Y1 )!

Cleaning and replacing the air filter (Illustration W )

IMPORTANT
Never let the engine start or run whilst the air filter is removed.
– Push the catches (1) to the back.
– Grasp the cover of the air filter (2) at the front at the lower edge, pull forward and upward and remove the cover.
– Remove pre-filter (3) and paper filter insert (4) from the air filter housing (5).
– Clean paper filter insert (4) every 100 operating hours.
When lightly soiled, knock clean carefully; replace if severely soiled or damaged. The paper filter should not be washed,
blown through with compressed air or rubbed with oil.
– Clean the pre-filter (3) every 25 operating hours.
Wash the pre-filter in warm water with a liquid cleaning agent and leave to dry thoroughly in the air. Do not rub the pre-
filter with oil.
– After cleaning or replacement, first insert the pre-filter and then the paper filter insert in the housing (5).
– Insert air filter cover with strap (6) in housing adapter (7). Press cover down and engage in the catch (1).
In the worst conditions (large amounts of dust) it is necessary to clean the mower whenever it has been used. Replace the
paper filter insert every year or every 300 operating hours.
