– 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.
Changing the drive V-belt
– The drive V-belt must be replaced by a
recommended expert 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 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.
For service work, close the petrol tap and always lay
the mower on the righthand side (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.
– The oil should be changed while the engine is still
warm.
– The oil can only be changed by extracting the
old oil via the oil filler neck.
– Hand pumps are available in specialist stores.
– Draw off the old oil into a collector. 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.
– After drawing off the old oil, add approximately
0.55 l of premium lubricating oil (cf. Technical
Data). Insert the dipstick and check the oil
level 9.
12. Causes of faults and their remedy
Fault
Engine does not start
Possible cause
– Switch handle not pressed
down.
– Petrol tap closed.
– No petrol.
Cleaning and replacing the air filter ]
– Loosen the screw (1) on the air filter cover (2) and
lift the cover.
– Remove preliminary filter (3) and paper filter element
(4).
– If the paper filter element is slightly dirty, knock out
until reasonably clean; if it is seriously clogged up
or damaged, it should be replaced (order no.
SA35945). Do not blow out the paper filter with
compressed air. Do not lubricate.
– Dirty preliminary filters should be washed in warm
water using a liquid detergent; then rinse out,
press out any excess water and leave to dry out
properly in the air. Dip the dry preliminary filter in
motor oil and squeeze out carefully (order no. of
preliminary filter: SA35944)
– Press the preliminary filter onto the paper
filter element and mount both in the air filter
plate (5).
– Place the cover on the air filter and tighten the
screw on the air filter plate.
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. SA32641. Otherwise it will be sufficient to
clean the spark plug with a steel brush and to set
the electrode distance to 0.7–0.8 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
– Provided the motor is still warm, extract off the oil.
Fill with fresh oil (approx. 0.55 l, see. technical
data).
Remedy
– Press switch handle to upper
part of handlebar.
– Open the petrol tap.
– Re-fuel.
