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.
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 15W40 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 (top edge of the flat-pressed
metal stick, Fig. N) and the minimum (bottom edge of
the flat-pressed metal stick, Fig. N). The moveable
orange plastic part on the oil dip stick provides
protection against oil foam.
Changing the oil:
Stand your lawn mower on a work bench with the
front right-hand wheel (in the pushing direction)
projecting beyond the edge of the work bench. Place
a flat oil pan beneath the lawn mower (Fig. O).
Remove the oil outlet screw on the underside of the
lawn mower (see Fig. P). Completely empty the used
oil. Screw the oil outlet screw back on tightly. Fill with
0.4 liters of fresh 15W40 engine oil (see Checking
the oil level).
5. Care and adjustment of the cables
Oil the cables at regular intervals and check that they
move easily.
Check the adjustment of the cables every time

before you use the machine.
5.1 Cable motor brake adjustment
Secure the motor brake lever with adhesive tape
(Fig. G)
Check the play setting between the setting screw
and the cable nipple (gap approx. 2-4 mm) (Fig.
Q+R)
If the adjustment is incorrect, it must be corrected
by undoing the setting screw and adjusting it.
(Fig. R)
5.2 Drive unit cable adjustment (Fig. U)
In the drive position of the clutch lever (Fig. J3), the
clutch lever (Fig. A/18) should be pulled up to the top
push bar. If the cable (Fig. U/1) is too taut, it must be
set to a longer length. To do this, undo the lock nut
(Fig. U/3) opposite the main cable (Fig. U/2), 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. A/18) so that it can just touch the top push
bar.
6. Maintenance of the air filter
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 (Fig. S). Clean the air
filter with compressed air or simply by knocking out
any soiling.
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
performed by a customer services workshop or
authorized specialist. The same applies to accessory
parts.
