7.2.2 Blades
For safety reasons, have all blade sharpening,
balancing and mounting work carried out by an
authorized service center. To achieve optimal re-
sults, 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 identifi cation
mark on the blade must correspond with the num-
ber specifi ed in the spare parts list.
Never install a blade from a diff erent manufactu-
rer.
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 da-
maged blade.
Resharpening the blade
The blade edges can be resharpened with a
metal fi le. To avoid imbalance, the blade reshar-
pening work should only be carried out by an
authorized service center.
7.2.3 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 sur-
face. Unscrew the oil dipstick (Fig. 9a/Item 7a) by
turning it counter-clockwise and wipe the dipstick.
Re-insert the dipstick into the fi ller opening as far
as it will go but do not screw it in. Pull out the dip-
stick, 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).
Change the oil
The engine oil is best changed at room tempe-
rature.
•
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.
7.2.4 Care and adjustment of the cable pulls
Oil the cable pulls at regular intervals and check
that they move easily.
7.2.5 Maintenance of the air fi lter (Fig. 10)
Soiled air fi lters reduce the engine output by sup-
ply too little air to the carburetor. If the air contains
a lot of dust, the air fi lter should be checked more
frequently.
Important: Never clean the air fi lter with petrol or
infl ammable solvents. Clean the air fi lter only with
compressed air or by tapping it.
7.2.6 Maintenance of the spark plug
Clean the spark plug with a copper wire brush.
•
Pull off the spark plug boot (Fig. 11/Item 14)
with a twist.
•
Remove the spark plug using a spark plug
wrench.
•
Assemble in reverse order.
7.2.7 Inspecting the V-belt
To inspect the V-belt, remove the V-belt cover (Fig.
12/Item 5b) as shown in Figure 12.
7.2.8 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.
Important: In accordance with the German
Product Liability Act, we are not liable for any
