remaining fuel is consumed.
Allow the engine to cool. Remove the grass collection bag. Loosen the quick release and fold down the top
section of the handles taking care not to bend the cables.
To avoid scratching the mower, insert corrugated cardboard or similar padding between the upper and
lower handlebars and the engine.
Due to the mower's weight, use ramps or seek assistance when lifting or loading the mower.
7.4 MOWER MAINTENANCE
Cutting system
Before and after each mowing session, check that the blade, its attachment bolts and drive shaft are not
damaged or excessively worn. Never try to straighten a bent blade. Replace a damaged, worn or bent
blade as soon as possible. Use only genuine parts. Excessive vibration when mowing is a good indication
of a problem with the cutting system.
WARNING: Vibration from a bent or damaged blade can cause costly damage to the mower. Working with
an excessively worn blade wastes fuel and can lead to injury if the blade becomes detached from the
machine.
Warning: there is a danger about moving blade. Always handle the blade when it is totally stopped. Wear
protective gloves.
Sharpening the blade
For best mowing results, have the edges sharpened and the blade balanced at least once a year by a
specialist service dealer or agent.
Removing the blade
Wear appropriate protective gloves to prevent possible injury when handling the blade. Disconnect the
spark plug cap and tilt the mower on its side with air filter and carburettor side uppermost.
Holding the blade firmly in one hand, use a spanner or socket to loosen the blade screw.
Mounting the blade
Wear appropriate protective gloves to prevent possible injury when handling the blade. Disconnect the
spark plug cap and tilt the mower on its side with air filter and carburettor side uppermost.
Check that all components (the blade, key, blade holder, screws and washers).are present, clean and in
good condition.
Position the blade on its support with the cooling fins facing the engine.
Check the correct alignment and matching of pads with the blade. The blade must be positioned precisely
on its stand.
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.
