8.2.2 Blades

For safety reasons, have all blade sharpening,
balancing and mounting work carried out by an
authorized service center. To achieve optimal results,
we recommend to have the blades checked once a
year.

Changing the blades (Fig. 8)

When changing the cutting unit, be sure to use only
genuine replacement parts. The identification mark
on the blade must correspond with the number
specified in the spare parts list. Never install a blade
from a different manufacturer.

Damaged blades

If, in spite of all caution, the blade comes into contact
with an obstacle, switch off the engine immediately
and pull the spark plug boot. Tilt the mower to the
side and check the blade for damage. Damaged or
bent blades must be replaced. Never straighten a
bent blade. Never work with bent or heavily worn
blades as this will result in vibrations, causing further
damage to the mower.

Important:

Risk of injury when working with a

damaged blade.

Resharpening the blade

The blade edges can be resharpened with a metal
file. To avoid imbalance, the blade resharpening work
should only be carried out by an authorized service
center.

8.2.3 Oil level check
Important:

Never run the engine with no or too little

oil. This can cause serious damage to the engine.

Checking the oil level

Place the lawn mower on a level and straight surface.
Unscrew the oil dipstick (Fig. 9a/Item 7a) by turning it
counter-clockwise and wipe the dipstick. Re-insert
the dipstick into the filler opening as far as it will go
but do not screw it in. Pull out the dipstick, hold it
horizontally and read off the oil level. The oil level
must be between the two marks min. and max. on the
oil dipstick (Fig. 9b).

Changing the oil

The engine oil is best changed at room temperature.

Place a flat oil drip tray beneath the mower.

Open the oil filler plug (Fig. 9a/Item 7a)

Open the oil drain plug (Fig. 9c/Item 7b). Drain
the warm engine oil into a drip tray.

Close the drain screw again when all the used oil
has been drained.

Fill in engine oil up to the top mark on the oil dip
stick

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.

8.2.4 Care and adjustment of the cable pulls

Oil the cable pulls at regular intervals and check that
they move easily.

8.2.5 Maintenance of the air filter (Fig. 10)

Soiled air filters reduce the engine output by supply
too little air to the carburetor. If the air contains a lot of
dust, the air filter should be checked more frequently.

Important:

Never clean the air filter with petrol or

inflammable solvents. Clean the air filter only with
compressed air or by tapping it.

8.2.6 Maintenance of the spark plug

Clean the spark plug with a copper wire brush.

Pull off the spark plug boot (Fig. 11/Item 13) with
a twist.

Remove the spark plug using a spark plug
wrench.

Assemble in reverse order.

8.2.7 Repair

After carrying out repair or maintenance work, ensure
that all safety parts are installed and in perfect
condition. Store potentially hazardous parts out of the
reach of other persons and children.
