Dust filter maintenance precautions one, do not remove the filter checks. Such a check is always more harm than good. When you release the gaskets, gasket sealing surface clean side. Insist on a regular maintenance schedule. Or if you decided to overhaul the flow resistance. Detailed gauge or indicator. Then replace the filter. Second, do not ignore the housing worn or damaged gasket. If you have an air filter seal. Intentions would have to replace it. Always test to ensure no old gasket left in the housing. And seal not worn. If your model requires each time a new filter gasket, you may not re-use the old gasket. Third, do not use a damaged plants Paste filter. No installation or protrusions of the filter, because they can not effectively prevent contaminants from entering. Depression may lead to seal uneven or damaged paper might imply. Filter paper pasted engines and will consume more fuel. Four, not knocking the filter to clean it. Tap filter is sufficient to knock the dust, but also damage the filter. And the destruction of your engine. Tap is not very deep pollutants. So that you can replace the filter work remains secure. Fifth, the filter can not be assessed by observation of life, to measure the air flow resistance. A filter looks dirty, it may still remain a longer life. While carbon-based pollutants in the eye can not see. You can not see the body of pollutants embedded in the paper. The lowest filter maintenance costs and engine protection best way is to follow the instructions to do differential pressure indicator. This is clever low-cost inputs. Six, the replacement of missing or damaged parts. Testing to ensure that no leaks may cause damage to air filter housing. Replace any loss of live damaged dust valve and air filter snaps. Do not attempt to repair a damaged filter. Open direct air filter is the engine inlet. In the process of replacing the filter, keep it well protected. We can see the pollutants cause engine damage. If the case is not immediately reload, cover the opening to ensure that nothing enters. Seven, not with an incorrect filter model to replace it. Filter looks almost exactly the same, but a fraction of an inch size difference in time, may impede or affect the air flow a good seal. Only in accordance with the selected paper size selection filter models may not be right. Affect the life and filter effects.
