Outstanding cutting performance and smooth running during operation make the 71 PM3 low kickback saw chain a great choice for both occasional and professional users. With 21% better cutting performance than 3/8” PMM3 as equipped on an MSA 160 C-BQ, this chainsaw requires lower force-feed and less engine power because of its narrow cutter profile. The 71 PM3 saw chain offers 33% better plunge cutting efficiency and 18% less vibration than 3/8” PMM3 as measured on an MSA 160 C-BQ. This standard saw chain for the MSA 160 C-BQ STIHL Lithium-Ion powered chainsaw is ideal for use on small electric corded, battery/cordless or gasoline chainsaws and pole pruners with less than 1.0 kW (1.34 bhp) power.         3/8"   1/4" .325" 3/8" .404" PICCO 0.043" 3670         If you need assistance with finding the correct chain, please use the Saw Chain Selection Guide
