Start by making sure the chainbrake is off, by pulling the hand guard fully to the top handle, now remove the side cover fixing nuts, or single nut if it has tooless chain adjustment, take away the side cover, wind the chain adjuster fully back, if it is in the cover wind the knurled wheel back, now lift the old chain off the bar and loop it over the sprocket and away, loop the new chain over the sprocket and lay it into the guide bar rail, with the cutting edge on the top of the bar facing away from the saw ( the chain rotates clockwise as you look at it ), re fit the side cover, make sure the adjuster pawl aligns with the hole in the guide bar, re fit the nuts finger tight, adjust the chain so as it touches all the way around the bar, now with a gloved hand pull the chain around the bar manually, this will ensure it is correctly in the sprocket, re adjust the chain if required ( it should not sag at the bottom of the guide bar ) now lift the bar nose and fully tighten the bar nuts.After ten minutes or so cutting re tention the chain.
