Servicing the rear wheel drive ¡
– Remove the transporter wheels from the wheel
axle after removal of the wheel cover and
loosening of the fixing nut.
– Remove dirt and any grease from the wheel cover,
from the free wheel pinion on the gear shaft and
the drive pinion on the inside of the wheel.
NOTE
Do not remove the free wheel pinion from gear shaft.
– Grease the pinion pair (free wheel pinion and
drive pinion in the wheel) with a plasticscompatible multipurpose grease, e.g.
FINA MARSON so that the toothed intermediate
spaces are completely filled.
– When pushing on the transporter wheel make sure
that the pinions engage; it may be necessary to
turn the wheel on the axle slightly.
Oiling the Bowden cable for gear actuation “
– Lubricate the Bowden cable every 10 hours of
operation, but at least once a month with thin
mineral oil. Slightly bend the Bowden cable in the
region of the point of lubrication for this purpose.
Checking and adjusting the Bowden cable for gear
actuation
The travel at the drive switch contact is 2 – 3 mm. It
can be adjusted by means of the adjusting screw
on the rive switch contact.
Servicing the drive
It is absolutely essential that the Bowden cable
(cf.“Oiling the Bowden cable”) is easy-running for
the perfect functioning of the control drive.
Changing the drive V-belt
– The drive V-belt must be replaced by a
recommended expert workshop.

Servicing the engine
The prescribed maintenance and service work must
be performed on a regular basis to ensure long and
fault-free life of the engine.
Keep the engine clean paying particular attention
to the exterior. The perforated plate of the fan wheel
must always be kept free from particles (e.g. grass
cuttings) in particular. Never spray clean with water
as this would result in damage to the ignition system
and carburettor.
Perfect cooling of the engine will only be guaranteed
if the cylinder fins are always kept clean.
Always lay the mower on the lefthand side for service work (tank and carburettor facing upwards)
since otherwise there could be starting difficulties.
Oil change ¶
The first oil change of a new engine is necessary after
5 operating hours, and thereafter every 50 hours of
operation or at least once per mowing season.
– To change the oil remove the dipstick from the
filler and lay the mower on its side so that the used
oil drains into the catch tray.
– Old oil should be disposed off in accordance with
the relevant local regulations and on no account be
discharged into the sewerage system or into the
ground.
– Turn the mower upright and fill approximately 0.6 l
quality oil (See Technical Data) through the filler.
Screw on dipstick and check oil level 9.
Cleaning and replacing the air filter ¢
– Loosen the screw on the air filter cover and open
the cover downwards.
– Carefully remove the filter insert (1) and tap out
on a smooth surface or replace if very dirty.
– Never oil the insert or blow with compressed air.
Very dirty or oily filter inserts must be replaced
(Order no. SA26547).
– Replacel in housing after cleaning or replacing
the filter element and carefully close the cover.
Where conditions are unfavourable (e.g. high levels
of dust), cleaning should be performed each time
the mower is used, otherwise every 3 months or
every 25 operating hours.
Checking the spark plug [
To check for wear, remove the spark plug connector
and unscrew the spark plug. If the electrode is
worn badly the spark plug must be replaced.
Order-no. SA16815. Otherwise it will be sufficient to
clean the spark plug with a steel brush and to set
the electrode distance to 0.75 mm. Screw in the
spark plug (pay attention to sealing ring) into the
engine by hand and tighten using the set screw
wrench. Press on spark plug connector.
Correct storage of the engine
(when not used for a long period of time)
– Let the engine run warm.
– Empty the petrol tank or allow the engine to run
until it stops due to lack of fuel
– Drain oil and add fresh oil.
– Unscrew the spark plug and fill approx. one
tablespoon motor oil into the cylinder.
– Ignite the engine using the starter several times
so that the oil is distributed evenly in the cylinder.
– Replace the spark plug.
– Pull through the starter slowly until the pressure
point is felt: the engine is now under compression,
the valves are closed, the combustion chamber is
protected against moisture.
– No guarantee is accepted for a resinified fueland
carburettor system or for rust damage within and
outside for the engine.
