CLEANING YOUR MAX-FLOW FILTER
When you remove the filter from the saw and see any dirt in the throat of the carburetor, or inside the cage, it is time to clean and re-oil the filter element. Ideally the filter should be cleaned BEFORE the oil has been used up and the particles are passing through the foam. Your attention to this and practice will determine the cleaning interval for your application. Read More...

OILING YOUR MAX-FLOW FILTER
Whether you have many spare elements or field clean your filter element whenever it gets dirty, it is important to thoroughly clean the the trapped dirt particles from the foam. This is an easy job, and with care it doesn't even need to be messy. Suggested oils are Bel-Ray, UNI or No-Toil. DO NOT use bar lube, it is not designed to be burned in an engine and will cause your rings to stick! We do not advise, motor oil, vegetable oil or gauze filter oil. None of them will efficiently trap the smaller dirt particles. Remember the quality of oil determines the effectiveness of the air filter. Read More...

After replacing the factory HD or HD2 air filter, most Stihl chainsaws (other than the MS661which has an auto-tune function) will require a slight air/fuel mixture adjustment. Here is how to accomplish this. Read More...

COST EFFECTIVE PERFORMANCE
Should you keep your existing chainsaw filter or upgrade to the Max-Flow Filter System? Compare the cost of keeping your present HD2 to the cost of our filter system. One Stihl® filter element costs $48.95. With a Stihl® recommended replacement of one filter a month, a year's cutting will cost $599.00. Using the same replacement interval, a Max-Flow Filter System with 10 extra filter elements is only $189.95, saving you over $400.00 each year. Spend less and get longer filter maintenance intervals too!
