Good advice from JW, most Poulan hobby machines run a 3/8 low profile chain 050 gauge, Stihl have some very odd gauge sizes they call pico and mini pico, so be aware.

You will have to know chain pitch,gauge,and drive links for both saws . If they are the same it will work. Many times the bar on the saws have this information
