Answer
I checked online for the Owner's Manual for that unit, since it's not a model we currently sell.
It says it can use an 18" bar and a 0.325 inch pitch along with .050, .058, or .063 gauge chain. The bar and chain have to work together as a team.
We sell a Husqvarna 18" replacement bar with .325 pitch; it's part number HLN250-72 meant for PIXEL chain systems on current models.
If you're not sure if your chain will work with this bar, please give the Husqvarna folks a call, toll free, at 800-487-5951. They will be happy to advise you on the most effective bar and chain combination for your particular saw.
