• Check all the screws and nuts once more before
you start to use the lawn mower again. Tighten any
loose screws.
• Also be sure to empty the grass basket (16).
• Pull the spark plug boot to prevent unauthorized
use.
• Ensure that you do not park the mower next to any
source of danger. Petrol fumes can lead to explo-
sions.
• Only original parts or parts approved by the manu-
facturer may be used for repairs (see address on
the warranty certificate).
• If the lawn mower is not going to be used for an ex-
tended period, empty the petrol tank using a petrol
suction pump.
• Oil and maintain the machine.
9. Maintenance and cleaning
• Regular, careful maintenance is required to guar-
antee the safety level and performance of the ma-
chine.
• Make sure that all nuts, bolts and screws are tight-
ened securely and that the machine is in safe work-
ing condition.
• Routinely check the grass basket for signs of wear
and impaired functionality.
Regularly clean the grass box with water and let it
dry thoroughly.
• For your own safety, replace worn or damaged
parts without delay.
• If the fuel tank should require emptying this should
only be done in the open air using a petrol suction
pump (available from DIY shops).
m WARNING
Never work on or touch conducting parts on the ig-
nition unit with the engine running. Always pull the
spark plug boot from the spark plug before starting
any work of care or maintenance. Never perform any
work on the machine while it is running. Any work not
described in these Operating Instructions must be
performed by an authorized service workshop only.
Pay attention to moving knife assemblies.
Cleaning
The mower should be thoroughly cleaned after each
use. In particular, the underside and the blade re-
tainer.
m Attention!
For safety reasons, disconnect the spark plug cable
before cleaning.
It is best to tilt the mower backwards. The spark plug
should point upwards to prevent engine oil from en-
tering the intake tract or leaking out.
Alternatively, you can tilt the device on its side, but
you must make sure that the air filter is on the upper
side.

Note: Before tilting the lawnmower, empty the fuel
tank fully with a fuel scavenge pump.
Do not tilt the lawnmower beyond 90 degrees.
It is easiest to remove the dirt and grass immediately
after mowing.
Grass residues and dirt that have dried on can im-
pair mowing. Check that the grass ejection channel
is clear of grass residues and remove these if neces-
sary.
Never clean the mower with a water jet or high pres-
sure cleaner. The motor should remain dry.
Do not use aggressive cleaning products such as
cold cleaners or white spirit.
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
