Mr. Hobby,
We are in receipt of and thank you for your e-mail. Besides
the first digit, which is the plant identifier number, all other numbers are
just random sequences. There is no way to tell the date of manufacture of
the unit except by registration and production records. If you will provide
me with the serial number, I will research it and tell you when the chainsaw
was manufactured. Anyone can contact us for this information, and that would be the only way to find it.
Thank you again for your e-mail.
Best regards,
Wayne Lemmond
