• Check the presence of clogging the fil-
tering element (RFE) without removing it
from the casing.
ATTENTION! It is not recommended to
take the RFE from the casing.
The RFE clogging indicates the damage
of MFE (breaking of paper blind, discon-
nection of the bottom). In this case flush
RFE and replace MFE.
• Blow the major filtering element with
compressed air first from inside and then
from outside to completely remove the
dust. To prevent the paper blind from
rupture, the air pressure shall be max
0.2-0.3 MPa (2-3 kgf/cm
2
).
The air jet should be directed at an angle
to the filtering element surface. When
servicing, protect the filtering element
against mechanical damages and oiling.
When the filtering element is oiled or
clogged so that the blowing with com-
pressed air is ineffective, it should be re-
placed.
• To reassemble the air cleaner, proceed in
the reverse order.
• Refit the right facing grid.
ATTENTION! Having reassembled the air
cleaner, check air tightness of all joints of
the inlet line; to do this, start the engine
and shut down air intake at a medium
speed of the crank shaft. When it will be
done, the engine shall stop quickly. Oth-
erwise, detect and eliminate looseness.
NOTE:.
