when looking for oil for the chain on a chainsaw google can easily send you astray, your better off googlieing the phrase saw chain, but for most electric chain saws what you want is called bar and chain oil or ur manual with this device will refer you to a Grizzly Service-Centre, that is if your reference to FHE 550 A1 relases to a small electric chain saw, it may also refer to a part number on some old washing machines which also use chains between their cogs, and I think the same oil would do the job but I am unsure, it would have been useful to mention the word chain saw if such is the case
