Never install another blade.
• Empty the fuel tank before removing the blade.
• Undo the screw to replace the blade.
• Reinstall as illustrated in fig. 17. Fasten the screw
correctly. The fastening torque is 45Nm. Also re-
place the blade screw when replacing the blade.
Damaged blades
Should the blade, in spite of all precautions, come
into contact with an obstruction, shut down the engine
immediately and remove the spark plug connector.
Tip the lawnmower onto its side and check the blade
for damage. Damaged or bent blades must be re-
placed. Never attempt to bend a bent blade back to
straight 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 mower.
m Attention! 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 re-
sharpened by an authorised service workshop.
Oil level check
m Attention! Never operate the engine without oil
or with too little oil. This could cause severe damage
to the engine. Only use SAE 30 / 10W-30 / 10W-40
engine oil.
Checking the oil level (fig. 18):
• Position the lawnmower on a straight, level surface.
• Remove the oil dipstick (12) by turning it to the left,
then wipe off the dipstick. Insert the dipstick back
in the filling nozzle as far as the stop, but do not
screw it back in.
• Pull out the dipstick and read the oil level horizon-
tally. The oil level must be positioned between the
max and min of the oil dipstick (12).
Oil change (Fig. 23)
• The engine oil change should be completed annu-
ally before the start of the season while the engine
is at operating temperature and shut off.
• Only use engine oil (SAE 30 / 10W-30 / 10W-40).
• Empty the fuel tank (with a petrol extraction pump).
• Place a flat oil collecting tray in front of the mower
(min. volume 1 litre).
• Unscrew the oil dipstick and tilt the mower until all
the oil has drained into the collection tray.
• Then fill in fresh engine oil up to the upper mark of the
oil dipstick (approx. 0.4 l), do not overfill the device.
• Attention! To check the oil level, do not screw in the
oil dipstick, but only insert it up to the thread.
Dispose of the used oil in accordance with applicable
regulations.

Cleaning the belts (fig. 17, 19)
• Remove the blade and the transmission housing by
undoing the screws.
• Clean the elements of the transmission and the
V-belt once or twice a year with a brush or com-
pressed air.
• Refit the transmission housing and the blade using
the screws.
Maintaining and adjusting the cables
Oil the cables at regular intervals and check that they
move easily.
Air filter maintenance (Fig. 20)
Contaminated air filters (7) diminish the engine output
due to reduced air supply to the carburettor. Regular
inspection is therefore essential.
The air filter (7) should be checked every 25 operat-
ing hours and cleaned as required. If the air is very
dusty, check the air filter (7) more often.
Unclip the air filter cover and remove the sponge filter
element. Replace the air filter to avoid objects falling
into the air intake (fig. 20).
Attention: Never clean the air filter (7) with petrol or
flammable solvents. Clean the air filter (7) only with
compressed air or by tapping it out.
Maintaining the spark plug (fig. 21)
Check the spark plug for contamination for the first
time after 10 operating hours and clean it with a cop-
per wire brush if necessary. Then service the spark
plug every 50 operating hours.
Remove the spark plug connector with a twist.
Remove the spark plug (10) with a spark plug wrench.
Use a feeler gauge to 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 engine
brake which must be checked regularly. When the
motor brake lever (3) is released, the blade must
come to a standstill within 7 seconds; if this is not
the case, the machine must not be used. Contact an
authorised specialist dealer.
Ensure that the device is in perfect condition for the
entire duration of its service life. Improper mainte-
nance may lead to life-threatening injuries.
Repairs
After repairs or maintenance, make sure that all safe-
ty-related parts are installed and are in perfect con-
dition. All parts which may cause injury must be kept
where they are inaccessible to children or others.
Attention: According to the German Product Liabili-
ty Act, no liability is accepted for damage caused by
improper repairs or by not using original spare parts.
