Cleaning the air filter

this may be because the air filter is clogged. When driving
with a dirty air filter the engine can suffer from lack of air, so
that it does not meet environmental requirements and the
engine does not provide full power.
Emptying the particle collector
Squeeze so that the rubber tabs open and the particles can
escape.
Cleaning the filter cover
Loosen the two fasteners holding the filter cover and remove
it.
Clean the inside of the lid. It can be washed with soapy water
and blown with compressed air when the lid is removed.

Maintenance
Replacing the air filter
!
If the engine seems to lack power or does not run smoothly
this may be because the air filter is clogged. It is therefore
important to replace the air filter at regular intervals (see
Maintenance/Maintenance Schedule for the correct service
interval).
Replace the air filter as follows:
Open the engine cover.
Loosen the two fasteners holding the filter cover and
remove it.
IMPORTANT INFORMATION
Never run the engine without the air filter fitted.
Poorly filtered inlet air is a main factor contributing to engine
wear. Replace the air filter according to the service
schedule or more often in dusty conditions
The filters must not be oiled. They must be fitted dry.
Remove the filter cartridge from the filter housing.
Wipe clean the interior of the air filter housing. If
necessary, the cleaning cloth should be moistened with
white spirit or fuel. Water or compressed air should not be
used.
Clean the filter by knocking it with care against a hard
surface. Do not use compressed air to clean the filter.
Replace the air filter if it is still dirty.
3 Fit a new air filter cartridge with the hole inward and press
it into place.
4 Replace the air filter cover, ensure that the particle
collector is facing downwards.
Cleaning the engine and muffler
Keep the engine and muffler free from grass cuttings and dirt.
Clipping debris soaked in fuel or oil on the engine means
increased risk of fire and impaired cooling.
Allow the engine to cool before cleaning. If the dirt is mixed
with oil, remove it using a degreasing agent otherwise just
water and a brush.
Grass cuttings around the muffler dry quickly and constitute a
fire risk. Brush or wash them off when the muffler is cold.
WARNING! The exhaust system is hot. Let it
cool before starting to replace the air filter.
