Swa chain can be prchased from any good chainsaw shop,all the need is the pitch of the chain the gauge and the drive link count, most electric saws run a 3/8 low prifile pitch 050 gauge ( 91sg ) the drive link count will give them the lenght. I have never heard of this model so can only give some guidence to fitting. Remove the nut/nuts holding the side cover on, if the chainbrake is located in the cover make sure it is off before removing, back off the chain adjuster screw and lift the chain out of the bar, once out you can lift the chain over and off the sprocket, assemble the new chain in reverse order, take care to align the adjuster pawl into the bar before re fitting the side cover, adjust as normal ( use a gloved hand when working with saw chain )
