Cleaning The Main Filter Cartridge - Kohler SFGLD480 Operation & Maintenance Manual

4. Verify the condition and appearance of the main filter cartridge: the filtering paper should be free from
excessive dirt or breakage. Check the paper folds for homogeneous distribution and absence of deformation.
Clean the filter cartridge in case of high dust concentration or if specified by the maintenance programme
(see point 2.2).
Fouling
detector
Both tangentially and radially sealed filters shall undergo other checks of their main cartridge, as follows:
1. Check the elasticity of the sealing gaskets, mounted on the cartridge, by pressing with your finger and
watching the gaskets recover their original form. Wipe the gaskets clean with a moistened cloth.
2. After checking the condition of the cartridge and cleaning or changing the filter if necessary or specified by
the maintenance programme, reassemble the filter, proceeding in reverse order of its disassembly.
3. Reset the mechanical fouling detector and check the general performance of the engine when restarted. For
gas engines, also check for correct carburetion, since the mixture could be leaner.

2.2. CLEANING THE MAIN FILTER CARTRIDGE

Before cleaning the main cartridge of air filters, the inspection process described in the previous section should
have been carried out.
Only the main cartridge may be cleaned (up to three times according to the maintenance schedule). The safety
cartridge has to be changed as and when specified in the maintenance programme; it may not be cleaned using
the procedures described below because they would damage the safety cartridge.
There are two methods for cleaning the main filter cartridge: Blow-through and Washing.
