Function
The centrifugal cleaning
is the first step in the air purifi -
cation of the inlet air.
The fins on the flywheel supply the cylinder with cooling air
(large arrow) while they are also the active part of the centrifugal
cleaning of the engine's inlet air. A centrifugal nozzle is fitted
next to the fins on the flywheel. The centrifugal force means that
large particles do not follow the curved air currents to the nozzle,
but are thrown to the outside of the nozzle. Only very small dust
particles manage to swing with the air currents to the inlet.
The paper filter
now has a more dust absorbing surface area
compared to its predecessor K1250.

Centrifugal cleaning
The inlet duct should be inspected and any deposits removed in
connection with filter replacement. Dust from dry cutting is
blown clean using compressed air. Material from wet cutting
normally needs to be scraped off mechanically.
Paper filter
The paper filter must not be cleaned, as it should be replaced,
whenever necessary with a new filter. The replacement frequency
is highly dependent on the material to be cut and if the cutting is
to be wet or dry. Replace the filter when the machine starts to
lose power.
Observe extreme caution when the filter is removed to ensure
that no dust particles fall down in the carburettor inlet. Removal
of waste is best done with a vacuum cleaner.
IMPORTANT!
Stone and concrete dust is the engine's biggest enemy!
Make sure the inlet elbow is intact and that it has a perfect seal
to the filter and the carburettor.
Dust in the inlet elbow indicate serious faults in the filter
system which must be corrected before operating this machine.
