7. Cleaning, maintenance, storage,
transport and ordering of spare parts
Important:
Never work on or touch conducting parts on the
ignition 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.
7.1 Cleaning
The lawn mower should be thoroughly cleaned
after every use, especially the underneath and
the blade mount. To do so, tip the lawn mower
onto its left side (the opposite side to the oil
filling socket).
Important: Before you tip the lawn mower onto
its side, completely empty the fuel tank using a
petrol suction 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 residue. 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.
7.2 Maintenance

7.2.1 Wheel axles and wheel hubs

These should be lightly greased once a season. To
do so, remove the wheel caps with a screwdriver
and slacken the fastening screws on the wheels.
7.2.2 Blade
For safety reasons you should only ever have
your blade sharpened, balanced and mounted
by an authorized service workshop. For optimum
results it is recommended that the blade should
be inspected once a year.
Changing the blade (Fig. 24)
Only ever use original spare parts when having
the blade replaced. The marking on the blade
must be matched with the number given in the
list of spare parts. Never have any other model of
blade fitted.
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.
Important: 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.
7.2.3 Checking the oil level (Fig. 14/15)
Important: Never run the engine with no or too
little oil. This could cause severe damage to the
engine.
Use only 10W30 engine oil.
Checking the oil level:
Stand the lawn mower on a flat level surface.
Unscrew the oil dip stick (15/Pos. A) by turning
anticlockwise, 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
again and read off the oil level while holding
horizontally. The oil level must be between the
maximum (Fig. 15/Item H) and the minimum (Fig.
15/Item L). The moveable orange plastic part on
the oil dip stick provides protection against oil
