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 le.
In order to avoid imbalance, the blade should be
resharpened by an authorized service workshop.
7.2.3 Checking the oil level (Fig. 14/15)
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 at level surface.
Unscrew the oil dip stick by turning
anticlockwise, pull out and wipe. Insert the dip
stick back in the lling mount as far as the stop,
but do not screw back in. Pull out the dip stick
again and read o the oil level while holding
horizontally. The oil level must be between the
maximum (Fig. 15/Item H) and the minimum (Fig.
15/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

7.2.4 Care and adjustment of the cables
Oil the cables at regular intervals and check that
they move easily.
7.2.4.1 Adjusting the cord for the engine
brake
If you notice a drop in the performance of the
engine brake, the cord (Fig. 17/Item A) will need
readjusting.
7.2.4.2 Drive unit cable adjustment (Fig. 18)
In the drive position of the clutch lever (Fig. 12),
the clutch lever (Fig. 1/Item 1) should be pulled
up to the top push bar. If the cable is too taut,
it must be set to a longer length. To do this,
undo the lock nut (Fig. 18/Item A) opposite the
main cable (Fig. 18/Item B), extend the screw
connection and then tighten the lock nut again.
If the power of the drive unit starts to fall, the
clutch tension must be increased using the
cable. To do this, the screw connection must be
reduced (using the method described above). Set
the clutch lever (Fig. 1/Item 1) so that it can just
touch the top push bar.
