12.1 Cleaning
The lawn mower should be thoroughly cleaned after
every use, especially the underneath and the blade
mount. To do so, tip the lawn mower onto its left side
(the opposite side to the oil filling socket).
Important: Before you tip the lawn mower onto its
side, completely empty the fuel tank using a petrol
suction pump. The lawn mower must never be tilted
by more than 90 degrees. Dirt and grass is easiest to
remove immediately after you have finished mowing
the grass. Dried on grass and dirt can result in
poorer mowing performance. Check that the grass
chute is free of any residual grass. Remove any such
residue. Never clean the lawn mower with a water jet
or high-pressure cleaner. The engine must remain
dry. Do not use aggressive cleaning agents such as
cold cleaner or petroleum ether.

12.2 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.
12.3 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. 25)
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.

12.4 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 (15/Pos. A) 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. 16/Item H)
and the minimum (Fig. 16/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 the
petrol service manual) when the engine is warm.
Use only engine oil (15W40).
Place a flat oil drip tray beneath the mower.
Open the oil filler screw (Fig. 15/Item A).
Open the oil drainage screw (Fig. 17). Drain the
warm engine oil into a drip tray.
Close the drain screw again when all the used oil
has been drained.
Fill up with engine oil as far as the top mark on the
dipstick.
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.
12.5 Care and adjustment of the cables
Oil the cables at regular intervals and check that they
move easily.
12.5.1 Adjusting the cord for the engine brake
If you notice a drop in the performance of the engine
brake, the cord (Fig. 18/Item A) will need readjusting.
12.5.2 Drive unit cable adjustment (Fig. 19)
In the drive position of the clutch lever (Fig. 13), 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.
19/Item A) opposite the main cable (Fig. 19/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.
