balance of the blade.
When reassembling the blade, make sure that the cutting edges are in the same direction
as the direction of rotation of the motor. The tightening torque of the blade screw should
be 3.7 kg * m / s 2 (37 Nm) and can be checked with a torque wrench.
Spark plug
Check the spark plug initially after the first five hours of mower use. Thereafter,
maintenance of the spark plug should take place every 25 hours.
Remove the spark plug cap using a rotary motion and then remove the spark plug with
the wrench provided.
Clean off any carbon deposits using a copper brush and check the electrode gap with a
feeler gauge.
Replace and retighten the serviced spark plug and replace the cap.
If the spark plug is worn or damaged, replace with a new spark plug of the same or
suitable type for the engine.
Air Filter
An air filter in poor condition will reducethe performance and life of the enginewhile
making it harder to start. Regular checks are therefore essential, especiallywhen using
the mower in dusty conditions. Check and clean the air filterevery 25 hours of use or
more often ifthe engine is used in a dusty environment.
Remove the air box lid and carefully remove the foam filtercartridge. Clean the cartridge
in a small bowl of warm water containing afew drops of washing
ϋ
up liquid until it is
perfectly clean and free from alltraces of grease and dust. Rinse the filter cartridge in
clean water and thensqueeze gently to remove most of the water. Let it air dry until it
iscompletely dry.
WARNING: Never clean the foam cartridge in petrol, white spirit or other solvents. These
products will degrade the filter cartridge.
Clean the cover and inside of the air box with a clean lint
ϋ
free cloth. Apply a uniform
layer of oil to the outside of the cartridge filter with a brush (you can use clean engine oil
for this). Insert the filter cartridge into its housing and replace the air box lid, ensuring that
each component is in place and properly installed. If the filter cartridge is damaged or is
very dirty, replace it using a genuine part.
The maintenance of a foam pre
ϋ
filter is identical to that of a foam cartridge filter, as
described above. The cartridge filter paper should be cleaned with a vacuum cleaner. If it
is dirty or contaminated with oil or petrol, replace it.
Clean the cover and inside of the air box with a clean cloth. Evenly apply a thin layer of
oil to the outside of the cartridge filter with a brush (you can use clean engine oil for this).
Replace the filter cartridge in its housing and then replace the lid of the air box, ensuring
that each component is in place and properly installed.
Adjusting the transmission cable
In its transmission
ϋ
engaged position, the mower’s advance lever is pushedfully towards
the handlebar. An incorrectly
ϋ
adjusted transmission cable cancause premature wear to
the mower’s drive system.
If the transmission cable is too tight, it will be difficult to move the advancelever towards
the handlebars. Conversely, if the transmission cable is not tightenough, the transmission
will function poorly and will lack power.
To adjust the tension of the cable transmission,increase or reduce the length of the
adjustmentdevice using the key. Check the effectivenessof the transmission and the
resistance of the lever.
Once proper adjustment has been reached, securethe adjustment device by tightening
the lock nuts.
