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 (Fig. 9)
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.

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 10W30 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 (Fig. 10b/Item H) and the
minimum (Fig. 10b/Item L). 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 (10W30).
Place a flat oil drip tray beneath the mower.
Open the oil filler screw (Fig. 10a/Item 11).

Open the oil drainage screw (Fig. 10a/Item 12).
Drain the warm engine oil into a drip tray.
Close the 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.
12.5. Care and adjustment of the cables
Oil the cables at regular intervals and check that they
move easily.
12.6. Maintenance of the air filter (Fig. 11a-11c)
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.
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.

12.7. Maintenance of the spark plug

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 (Fig. 12a/Item 23)
with a twist.
Remove the spark plug with the supplied spark
plug wrench.
Assemble in reverse order.
12.8. Repairs
After any repair or maintenance work, check that all
safety-related parts are in place and in proper
working order.
All parts which may cause injury must be kept where
they are inaccessible to children or others.
Important: In accordance with product liability
legislation we are not liable for any damages caused
by improper repairs or the use of spare parts that are
not original spare parts or parts approved by us. In
addition, we are also not liable for any damages
arising from improper repairs. Such work should be
performed by a customer services workshop or
authorized specialist. The same applies to accessory
parts.
