THE AIR FILTER IS AN IMPORTANT COMPONENT OF THE DIESEL ENGINE AIR SUPPLY SYSTEM, WHICH CAN PURIFY THE AIR ENTERING THE INTAKE PIPE. IF THE AIR FILTER IS NOT MAINTAINED IN A TIMELY OR CORRECT MANNER, IT CAN CAUSE SERIOUS EARLY WEAR OF COMPONENTS SUCH AS CYLINDER LINERS, PISTON RINGS, AND INTAKE AND EXHAUST VALVES, RESULTING IN A DECREASE IN ENGINE POWER AND EVEN A SERIOUS SHORTENING OF THE ENGINE'S SERVICE LIFE.THE SPECIFIC MAINTENANCE METHOD IS: WHEN THE DUST IN THE DUST COLLECTION CUP EXCEEDS 1/3, IT MUST BE REMOVED, AND THE DUST IN THE CENTRAL PIPELINE SHOULD BE REMOVED IN A TIMELY MANNER. WHEN INSTALLING THE DUST COLLECTION CUP, IT IS NECESSARY TO INSTALL THE GASKET AND PAY ATTENTION TO ITS SEALING. REGULARLY CHECK AND REPLACE THE OIL IN THE OIL PAN OF THE OIL BATH AIR FILTER. THE OIL LEVEL SHOULD NOT EXCEED THE RING GROOVE IN THE OIL PAN TO PREVENT OIL FROM BEING SUCKED INTO THE CYLINDER, CAUSING CARBON BUILDUP OR RUNAWAY. WHEN THE OIL BECOMES THICK AND HAS POOR FLUIDITY, IT SHOULD BE CLEANED AND REPLACED IN A TIMELY MANNER. THE FILTERED WASTE OIL SHOULD BE DILUTED WITH 1/3 DIESEL IN WINTER. CLEAN THE METAL FILTER SCREEN IN A TIMELY MANNER ACCORDING TO THE OPERATING CONDITIONS. WHEN INSTALLING, WAIT FOR THE CLEANING OIL TO DRIP DRY BEFORE SOAKING IT IN THE ENGINE OIL. WAIT FOR EXCESS ENGINE OIL TO FLOW OUT BEFORE ASSEMBLING. DRY PAPER FILTER CARTRIDGES CANNOT BE CLEANED WITH DIESEL. DURING MAINTENANCE, GENTLY TAP AND SHAKE THE DUST AT BOTH ENDS OF THE FILTER CARTRIDGE, THEN USE A SOFT BRISTLED BRUSH TO CLEAN IT OR BLOW IT CLEAN FROM THE BACK WITH COMPRESSED AIR.
