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, always close the petrol tap and ventilation valve (1) A , 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.
The first oil change of a new engine is necessary after 8 operating hours, and thereafter every 100 hours of operation or at
GB
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 )!
Oil filter change (Illustration X )
Replace the oil filter annually or after every 200 operating hours during the course of an oil change. (Order no. see original
spare parts and accessories)
–
Drain the oil (see oil change).
–
Screw off the oil filter (1).
–
Lightly lubricate the seal of the new oil filter with new clean oil.
–
Screw on the oil filter hand-tight, until the seal makes contact with the oil filter adapter. Then tighten further by approx.
1/2 to 3/4 of a turn.
–
Add high quality oil (for quantity and type, see technical data) into the filler.
Insert the dipstick and check oil (see illustration Y1 )!
–
–
Start the engine and allow to idle. Check for oil leakage and, if necessary, tighten the filter further.
–
Recheck the oil level and, if necessary, add more oil.
Do not dispose of the oil filter as normal household waste. Dispose of it at a public collection point or authorised
specialist workshop.
Cleaning and replacing the air filter (Illustration W )
IMPORTANT
Never let the engine start or run whilst the air filter is removed.
–
Turn the air filter cap (1) anti-clockwise and remove it.
