4/5/2023 0 Comments Stihl serial number year madeThe Stihl 025 chainsaw is equipped with a chain brake that can be operated manually by the user, and it is also activated automatically by inertia when the hand guard in front of the handle moves suddenly toward the nose of the bar, as may happen when the saw kicks back. Use of gasoline with a lower octane rating, the manufacturer claims, increases the chance of pre-ignition, high engine operating temperatures and piston seizure. Stihl also recommends the use of gasoline with a minimum octane rating of 89 in the 025. Two-cycle engine oils are designed for high-performance engines such as those in chain saws, and they will help prevent problems such as pre-ignition and ring sticking. To achieve this ratio, combine 2.6 fluid ounces of oil with each gallon of gasoline, adding the oil to an appropriate mixing container first, followed by the gasoline. Stihl specifies that the 025 be fueled only with unleaded gasoline and a high-quality oil intended for use in two-stroke engines at a ratio of 50 parts gasoline to 1 part oil.
