petrol. Keep petrol away from children.
11. Oil and maintain the machine.
12. How to switch off the engine:
All you have to do to switch off the engine is
release the engine start/stop lever (Fig.
10/Item A). Close the petrol cock and pull the
spark plug boot from the spark plug boot in order
to prevent the engine from restarting. Before you
start the engine again, check the cord for the
engine brake. Check that the cord is correctly
fitted. If the cord is kinked or damaged, it should
be replaced.
12. Care and maintenance
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.
12.1. Cleaning the lawn mower
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.
12.2. 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.
12.3. 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
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 (Fig. 19)
The blades can be resharpened with a metal file. In
order to avoid imbalance, the blade should be
resharpened by an authorized service workshop.
12.4. Checking the oil level
Important: Never run the engine with no or too little
oil. This could cause severe damage to the engine.
Use only 15W40 engine oil.
Checking the oil level:
Stand the lawn mower on a flat level surface.
Unscrew the oil dip stick 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 (top edge of the flat-pressed
metal stick, Fig. 16) and the minimum (bottom edge
of the flat-pressed metal stick, Fig. 16). The
moveable orange plastic part on the oil dip stick
provides protection against oil foam.
Changing the oil
Change the engine oil every year before the start of
the season (in addition to the information in the
petrol service manual) when the engine is warm.
Use only engine oil (15W40).
Place the mower on a work table with the right-
hand front wheel (in the pushing direction)
projecting free of the table.
Place a flat oil drip tray beneath the mower.
Open the oil filler screw (Fig. 15/Item A).
Open the oil drainage screw (Fig. 17). Drain the
