pull out and wipe. Insert the dip stick back in the filling
mount as far as the stop, but do not screw back in.

level while holding horizontally. The oil level must
be between the maximum and the minimum
Changing the oil (Fig. 23)
• Change the engine oil every year before the start of
the season when the engine is warm.
• Use only engine oil (SAE30).
• Empty the fuel tank (with a petrol suction pump)
• Place a flat oil drip tray in front of the mower (min.
volume 1 litre).
• Remove the dipstick and tip over the mower until
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. 0.5 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 loosen-
ing 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 (Fig. 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. (Fig. 20).
Important: Never clean the air filter with petrol or in-
flammable cleaning agents. Clean the air filter with
compressed air or simply by knocking out any soiling.
Maintenance of the spark plug (Fig. 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").
Replace the spark plug (10) and take care not to pull
it too firmly.
Engine brake lever (Fig. 1)
The engine is equipped with a mechanical brake (3)
which has to be checked regularly. When releasing
the brake lever, the blade must come to a halt within
7 seconds. If this is not the case, the machine must
not be used. Contact an authorised specialist retailer.
Ensure that the machine is in a flawless condition for
its entire service life. Improper maintenance may lead
to life-threatening injuries.
