How long does a chainsaw bar last?
The life of any product depends on its uses. If you use it frequently, it may not last long. For rarely used it may last very long. However, for average use, it will definitely run smoothly for around 5 years. I would also recommend you to properly clean it before cutting it and cut it in the proper position. Use lubricant frequently. These small steps may help to enhance the lifespan of the bar.
