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 run the engine with no or too lit-
tle oil. This could cause severe damage to the engine.
Only use SAE30 / 10W-30 / 10W-40 engine oil.
Check the oil level (Fig. 19):
• 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. 24)
• 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 (SAE30 / 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).
• Remove the oil dipstick and tip over the mower until
all of the oil has drained into the oil collecting 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. 20)
• 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. 21)
Contaminated air filters (10) diminish the engine out-
put due to reduced air supply to the carburettor. Reg-
ular inspection is therefore essential.
The air filter should be checked every 25 operating
hours and cleaned as required. The air filter must be
checked more often in case of very dusty air.
Unclip the air filter cover and remove the sponge filter
element. Replace the air filter to avoid objects falling
into the air intake (fig. 21).
Attention: Never clean the air filter with petrol or com-
bustible solvents. Clean the air filter with compressed
air or simply by knocking out any soiling.
Spark plug maintenance (Fig. 22)
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. Re-
move the spark plug (h) with a spark plug wrench.
Use a feeler gauge to set the gap to 0.75 mm( 0.030").
Refit the spark plug (h), taking care not to over-tighten
it.
Engine brake lever (fig. 1)
The motor is equipped with a mechanical brake that
must be checked regularly. When the brake lever (3)
is released, the blade must come to a standstill within
7 seconds; if this is not the case, the appliance 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 maintenance 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 liability
act, no liability is accepted for damage caused by im-
proper repairs or by not using original spare parts.
Such work should be performed by a customer ser-
vice centre or an authorised specialist. The same ap-
plies to accessory parts.
