* For the frequency and timing of cleaning, refer to the relevant instruction manual. More frequent cleaning than necessary could damage the element or cause dust and foreign matter to be sucked into the engine.* Do not strike the element or hit it against another object to remove dust.* Do not blow compressed air against outside surfaces of the element.
Inspection Procedure Inspection: Outer Element* Shine some electric light inside the element.* Replace the element if thin spots or broken parts are evident in the filter paper, or if the packing at the top of the element is damaged. Also replace the element if the dust on the element is damp with oily smoke or soot, regardless of the replacement schedule. Inspection: Operation of dust indicator under specific negative pressure * Perform the following inspection and, if faulty, replace the dust indicator.* With no vacuum applied to the dust indicator, take measurement between the terminals 1 and 2. There should be no continuity.* Gradually apply vacuum to the dust indicator. Measure the vacuum when the continuity is made between the terminals 1 and 2.Turbocharger

This line will serve as mating marks in the installation procedure. Removal Procedure Removal: Turbine housing
* Tap all around the end of the turbine housing with a rubber hammer or a similar tool, being careful not to damage the turbine housing.* Do not let the blades of the cartridge assembly hit the turbine housing, as they are easily bent.
Removal: Compressor Cover
* Tap all around the end of the turbine housing with a rubber hammer or a similar tool, being careful not damage the turbine housing.* Do not let the blades of the cartridge assembly hit the turbine housing, as they are easily bent.
Work after Disassembly Cleaning* Before cleaning the parts, carry out a visual inspection for any marks of burns or wear that may become difficult to find after the cleaning. If any defects are evident, replace the part(s).* Immerse the disassembled parts in an inflammable solvent (a 5 to 10 aqueous solution of Oil Clean from New Hope Co., Ltd.). Take out the parts from the solvent and dry them with compressed air. If there is any solid matter remaining on the parts, remove them with a plastic scraper or a bristle brush.
