The STIHL connected portal is the digital workplace specially for commercial use.
STIHL uses a Marketing Number System in addition to the part number. Stihl chain saws, for example, have the serial number printed on the crankcase or �. This allows easy identification of any chain. On the bar side of the saw does it say 'Stihl 08' or 'Stihl 08S'? Warm up the saw for 5-10 minutes. As each model of Stihl equipment is unique, so is its placement of the serial number.
We have gleaned this information from the Stihl USA Web site.
