instructions of the respective mower.
– Reassemble in reverse order, if necessary fit the
curved washer, the bushing and blower wheel
with flange onto the shaft first. Ensure that the
revolving edge of the sliding washer faces away
from the blade. The raised ends of the blade
should face the housing.
– Tighten the blade fixing screw with a dynamometric
wrench to 40-45 Nm. Do not use an
impact screwdriver.
ATTENTION
Do not leave any tools in the mower!
Before starting the mower check that all tools
have been removed!

Servicing the wheels
Front wheels
Lubricate the bearings of the wheels once a year or
every 20 operating hours.
– Release the hexagon nuts using a socket
spanner and remove the wheels.
– Having dripped oil into the bearings, push on the
wheels and tighten so that they can still be turned
easily.
Servicing the rear wheel drive
– Remove the drive wheels from the wheel axle after
removal of the wheel cover and loosening of
the 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 plastics-compatible
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.
Servicing the drive
– It is absolutely essential that the Bowden cable is
easy running for switching on and off, so that the
control drive works perfectly.
– Lubricate the Bowden cable every 10 hours of
operation with thin mineral oil. Slightly bend the
Bowden cable in the region of the point of lubrication
for this purpose.
– The Bowden traction mechanism has been set
ready for operations at the works and requires no
adjustment.
GB
Changing the drive V-belt
The drive V-belt must be replaced by a specialist
workshop.
11. 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. 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.
For service work push operating lever (1) into
position (2) (see ill. /) and lay the lawnmower on its
left side, since otherwise there could be starting
difficulties.
Cleaning and replacing the air filter ¢
Clean the paper air filter every 25 hours of operation
and replace after every 100 hours of operation, and
after every operation if there is a lot of dust.
– Loosen the two red wing nuts and remove
the cover.
– Remove foam prefilter from paper filter and wash
in soapy water (approx. 1.5 l water at a minimum
temperature of 40°C mixed with approx. 0.1 l
detergent) and squeeze clean.
– Then shake the foam prefilter and dry well.
– Clean paper filter by tapping out or using weak
compressed air.
– Clean cover and filter housing with a lightly oiled
clean cloth.
– If the seal of the filter holder is damaged always
replace both parts together. Order No. SA21863
Checking the spark plug [
Danger!
Highly inflammable.
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. SA21865. Otherwise it will be sufficient to clean
the spark plug with a steel brush and to set the
electrode distance to 0.5 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)
– Drain the fuel mixture from the tank and allow the
engine to run until it stops through lack of fuel.
