This particular model does not show up on the Oregon chain website. However you should be able to take it to any real major chain saw dealer (not wal-mart, fleet-farm, Home Depot or other big box stores) and they should be able to measure the current chain and have on your way to cutting bliss. I think the worse case would be you need to purchase a new bar with the chain in which place you'll know which chain you need based on the replacement bar that is purchased.
