Tighten the screws connecting all of the components. Make a final visual check that all
parts are present and aligned before tightening the fixing bolt very firmly with a wrench
while holding the blade firmly in one hand (NB wear suitable gloves).
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 reduce
the performance and life of the engine
while making
it harder to start. Regular checks are therefore essential, especially
when using the mower
in dusty conditions. Check and clean the air filter
every 25 hours of use or more often if
the
engine is used in a dusty environment.
Remove the air box lid and carefully remove the foam filter
cartridge. Clean the cartridge in
a small bowl of warm water containing a
few drops of washing up liquid until it is perfectly
clean and free from all
traces of grease and dust. Rinse the filter cartridge in clean water
and then
squeeze gently to remove most of the water. Let it air dry until it is
completely 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
‐
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.
WARNING: Do not twist the cartridge to clean foam, as you could damage it. This mower
is equipped with a dual filtration system comprising a foam pre
‐
filter and a cartridge filter
paper.
The maintenance of a foam pre
‐
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
‐
engaged position, the mower’s advance lever is pushed
fully towards
the handlebar. An incorrectly
‐
adjusted transmission cable can
cause premature wear to
the mower’s drive system.
If the transmission cable is too tight, it will be difficult to move the advance
lever towards
the handlebars. Conversely, if the transmission cable is not tight
enough, the transmission
will function poorly and will lack power.
To adjust the tension of the cable transmission,
increase or reduce the length of the
adjustment
device using the key. Check the effectiveness
of the transmission and the
resistance of the lever.
Once proper adjustment has been reached, secure
the adjustment device by tightening the
lock nuts.
