To do so, tilt the lawnmower to the left side (the oppo-
site side to the oil filling socket) and remove the grass
remnants or clean the device with water as follows.
• Remove the mulch insert / take off the grass bag.
• Attach the hose-connection piece to the mower (w)
and open the water tap. (Fig. 25)
• Start the mower and switch off after approx. 30 sec.
The rotating blade bar dashes the water against the
underside of the mower and in doing so cleans it.
• Close the water tap and disconnect the hose-con-
nection piece.
• Clean the top side with a cloth (do not use sharp
objects).
m Note! Before you tip the lawn mower onto its side,
completely empty the fuel tank using a petrol suc-
tion pump. The lawn mower must never be tilted by
more than 90 degrees. Dirt and grass is easiest to
remove immediately after you have finished mowing
the grass. Dried on grass and dirt can result in poorer
mowing performance. Check that the grass chute is
free of any residual grass. Remove any such resi-
due. Never clean the lawn mower with a water jet or
high-pressure cleaner. The engine must remain dry.
Do not use aggressive cleaning agents such as cold
cleaner or petroleum ether.
Wheel axles and wheel hubs
• These should be lightly greased once a season.
Blade
For safety reasons you should only ever have your
blade sharpened, balanced and mounted by an au-
thorized service workshop. For optimum results it is
recommended that the blade should be inspected
once a year.
Changing the blade (Fig. 17)
Only ever use original spare parts when having the
blade replaced.
Wear gloves when replacing the blade in order to pre-
vent 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. 17. 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 en-
gine 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 re-
sharpened by an authorized service workshop
Checking the oil level
m CAUTION! Never run the engine with no or too lit-
tle oil. This could cause severe damage to the engine.
Use only SAE30 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 (SAE30/ 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. 0.45 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)
Only for powered lawn mowers
• 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.
