6.4.8.3 Operation 80. Maintenance of the engine air cleaner
Maintenance of the engine air cleaner shall be performed when the indicating lamp
of the air cleaner filter maximum clogging flashes on, which is located in the control indica-
tor unit on the instrument board.
If the indicating lamp flashes on, it is required to replace the main filter cartridge
(MFC). To replace the MFC, perform the following:
- open the tractor hood mask to get an access to the air cleaner;
- pull yellow locking device 1 (figure 6.4.53), turn cover 2 counterclockwise and re-
move it;
- withdraw main filter cartridge 3 carefully;
- clear inside and sealing surface of the housing with wet cloth from dust and dirt. It
is necessary to prevent air duct from dust and dirt ingress;
- assembly of the air cleaner shall be carried out in the reverse order;
- make sure that MFC installation is carried out correctly and close locking device 1;
- put the tractor hood mask back to its place.
ATTENTION: MANUFACTURER OF THE AIR CLEANER STRONGLY RECOM-
MENDS TO CARRY OUT MFC CHANGING RATHER THAN CLEANING, TO AVOID EN-
GINE DAMAGING AND TO PROVIDE ITS MAXIMUM PROTECTION!

Figure 6.4.53 – Check of the engine air cleaner
If filter clogging indicating lamp flashes on and there is no possibility to replace MFC
at once, clearing of MFC is allowed.
To clean MFC, perform the following:
- blow off the main filter cartridge carefully with dry compressed air inside-out until
dusting is stopped. To avoid paper shutter breakage, air pressure shall be from 0.2 to 0.3
MPa. Air stream shall be pointed at the direct angle to the filter cartridge surface. During
maintenance it is necessary to protect the filter cartridge from mechanical damage and oil-
ing;
- check MFC for possible failures (shutter breakage, bottom coming unstuck);
- wipe the MFC O-ring with wet cloth and install the MFC into the air cleaner hous-
ing.
Cleaned MFC does not have the same service life as a new one.
IT IS FIRBIDDEN TO BLOW OFF MAIN FILTER CARTRIDGE WITH EXHAUST
GASES, RINSE IT AND DUST!
