the higher the tool speed the faster the blades heat, evaporate the oil, and run dry.
Air Line Lubrication Air line filter-lubrication is a necessity for long life of your tools. Oil injected in the tool and reconnecting to the air line lasts from 3 to 10 minutes of the tool running: the higher the tool speed the faster the blades heat, evaporate the oil, and run dry. Most blades travel a distance equal to 1.2 miles in one minute (over 100 feet per second) and centrifugal force gives even a small blade a weight equal to 5 or 6 pounds. The heat that is generated without oil will cause blades to chip and the chips get in bearings and cause failure. Dry blades heat, stick, and break or wear out in 20 hours or less. Properly lubricated blades can last 2,000 hours or more. How much oil is needed per minute of running? See chart below for the average use.
