How do you rePlace the chain on the 455 rancher?

You take the chain cover off of the bar. It is two nuts. Take them off and the cover will come off. Slide the bar toward you and the chain will become slack. You can then slide off the chain from the sprocket. To put a new one on. You will need to turn the chain adjustment back all the way to the left. Then put the chain back over the sprocket, then onto the bar. Put the chain cover back on and tighten the chain back up. Then tighten the two nuts back to tight.
