Turn the Homelite 150 chain saw upside down and look at the bottom of the case to find the small, metal identification tag. The serial number should be on the tag.
Write down the serial number.
Call Homelite's toll-free customer service line at 800-242-4672 and ask for a company representative.
Give the customer-service representative the serial number of your Homelite chain saw, and any other information they may need about the saw, and they will be able to provide the date your saw was made.
