Wheel axles and wheel hubs
• These should be lightly greased once a season.
Blade
For safety reasons you should only ever have your bla-
de sharpened, balanced and mounted by an authorized
service workshop. For optimum results it is recommen-
ded that the blade should be inspected once a year.
Changing the blade (Fig. 13)
Only ever use original spare parts when having the
blade replaced.
Wear gloves when replacing the blade in order to
prevent injury.
Never have any other blade fitted.
• Empty the fuel tank before removing the blade
• To replace the blade, undo the screw.
• Reinstall as illustrated in Fig. 13. Tighten the screw
properly. Tightening torque 45 Nm. When replacing
the blade, the blade screw should also be replaced.
Damaged blades
Should the blade, in spite of all precautions, come
into contact with an obstruction, shut down the
engine immediately and pull the spark plug boot. Tip
the lawn mower onto its side and check the blade for
damage. Damaged or bent blades must be replaced.
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 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 SAE30 engine oil.
Checking the oil level (Fig. 14-15):
• Stand the lawn mower on a flat level surface.
• Unscrew the oil dip stick (10) 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 (10) again and read off the oil
level while holding horizontally. The oil level must
be between the maximum and the minimum
Changing the oil (Fig. 19)
• Change the engine oil every year before the start
of the season when the engine is warm.
• Use only engine oil (SAE30).
• Remove the blade.
• Place a flat oil drip tray beneath the mower.
• Check if the opening to the oil pan is free.
• Open the oil filler screw (Fig. 14).
• Open the oil drainage screw (Fig. 19). Drain the
warm engine oil into a drip tray.
• Close the cleaned drain screw again when all the
used oil has been drained.
• 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.
Care and adjustment of the cables
Oil the cables at regular intervals and check that they
move easily.
Maintenance of the air filter (Fig. 16)
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. 16).
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 (Fig. 17)
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 (8) with a spark plug wrench.
Using a feeler gauge, set the gap to 0.51 mm. Refit
the spark plug taking care not to overtighten.

all safety-related parts are in place and in proper
