STIHL uses a Marketing Number System in addition to the part number. This allows easy identification of any chain. For example, chain with a Marketing Number of 33 RS3:
|3/8″||.050″||STIHL RAPID™||Super||Single-Humped Drive Link|
Number of Drive Links in Reels
3/8″ STIHL PICCO™
ANSI B175.1 Chain Saw Kickback Standard
STIHL’s green and yellow color code system serves to identify STIHL bars and chains with different kickback reduction characteristics. Green (go) marks those products which are designed to reduce the risk of kickback injury and comply with the ANSI B175.1 kickback standard. STIHL’s low-kickback chain features a green tie strap that identifies each loop as “low-kickback” chain that meets the ANSI standard. Recommended for both the experienced and inexperienced chainsaw user. Yellow (caution) marks products with increased risk of kickback injury. They are for use only by persons with extraordinary cutting needs and experience and specialized training in dealing with kickback conditions.
