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. 27)
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
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 (Abb. 16/Pos. 8) 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. 17/Item
max.)
and the minimum
(Fig. 17/Item min.)
. 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.
앬
Place a flat oil drip tray alongside the mower.
앬
Open the oil filler plug (Fig. 16/Item 8)
앬
Tilt the lawn mower over the oil drip tray.
앬
Let the oil run out through the oil filler opening.
앬
Stand the lawn mower back on its wheels.
앬
Fill in engine oil up to the top mark on the oil dip
stick
앬
Dispose of the used oil in accordance with
applicable regulations.
7.2.4 Care and adjustment of the cables
Oil the cables at regular intervals and check that they
move easily.
7.2.5 Maintenance of the air filter (Fig. 23-24)
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.
7.2.6 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.
앬
Pull off the spark plug boot (Fig. 25) with a twist.
앬
Remove the spark plug with the supplied spark
plug wrench.
앬
Assemble in reverse order.
7.2.7 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
