again. Never mow the lawn with a bent or heavily
worn blade as this will cause vibrations and can lead
to further damage to the lawn mower.
m CAUTION!
There is a risk of injury if you work
with a damaged blade.
Resharpening the blade
The blades can be resharpened with a metal file.
In order to avoid imbalance, the blade should be
resharpened by an authorized service workshop
Checking the oil level
m CAUTION!
Never run the engine with no or
too little oil. This could cause severe damage to the
engine. Use only SAE 30 / 10W30 engine oil.
Checking the oil level (Fig. 18):
• Stand the lawn mower on a flat level surface.
• Unscrew the oil dip stick (12) by turning anticlock-
wise, pull out and wipe. Insert the dip stick back
in the filling mount as far as the stop, but do not
screw back in.
• Pull out the dip stick (12) again and read off the oil
level while holding horizontally. The oil level must
be between the maximum and the minimum
Changing the oil
• Change the engine oil every year before the start
of the season when the engine is warm.
• Use only engine oil (SAE 30 / 10W30).
• Empty the fuel tank (with a petrol suction pump)
• Place a flat oil drip tray in front of the mower (min.
volume 1 Liter).
• Remove the dipstick and tip over the mower untill
the whole oil is run out into the oil drip tray.
• Fill up with engine oil as far as the top mark on the
dipstick (approx. 0.6 l).
• Important! Do not screw in the oil dipstick to check
the oil level – only insert it as far as the thread.
Dispose of the used oil in accordance with applicable
regulations.
Cleaning the belts (Fig. 17, 19)
• Remove the knife and the gear housing by loose-
ning the screws out.
• Clean the elements of the transmission and the
belt once or twice a year with brush or compressed
air.
• Screw the transmission housing and the knife on
again.
Care and adjustment of the cables
Oil the cables at regular intervals and check that they
move easily.
Maintenance of the air filter (Abb. 20)
A soiled air filter will reduce the performance of the
engine because it will prevent enough air getting to
the carburetor. It is therefore imperative that regular
checks are made. The air filter should be checked
every 25 hours and cleaned if required. If the air
is very dusty the air filter should be checked more
regularly.
Unclip the air filter cover and remove the sponge
filter element. To avoid objects falling into the air
intake, replace the air filter cover. (Abb. 20).
Important: Never clean the air filter with petrol or
inflammable cleaning agents. Clean the air filter with
compressed air or simply by knocking out any soiling.
Maintenance of the spark plug (Abb. 21)
Check the spark plug for dirt and grime after 10 hours
of operation and if necessary clean it with a copper
wire brush. Thereafter service the spark plug after
every 50 hours of operation.
Pull off the spark plug boot with a twist. Remove the
spark plug (10) with a spark plug wrench.
Using a feeler gauge, set the gap to 0.75 mm( 0.030").
Refit the spark plug taking care not to overtighten.

10. Storage

• Never store the mower (with petrol in the tank)
inside a building in which petrol fumes could come
into contact with open flames or sparks.
• Allow the motor to cool before you put the lawn
mower in an enclosed area.
• In order to avoid fire hazards, keep the engine, ex-
haust and the area around the fuel tank free from
grass, leaves and leaking grease (oil).
Preparing the mower for long-term storage
Caution: Do not empty the petrol tank in enclosed
areas, near fire or when smoking. Petrol fumes can
cause explosions and fire.
• Clean and maintain the machine before storage.
• Empty the petrol tank with a petrol suction pump.
• Start the engine and let it run until any remaining
petrol has been used up.
• Change the oil at the end of every season. To do
so, remove the used engine oil from a warm engi-
ne and refill with fresh oil.
• Remove the spark plug from the cylinder head. Fill
