The first 3 digits of all serial #'s stamped into Robert Bosch indicates the manufacturing date. The designation changes every ten years. So with the tables provided above, it looks to me like: Jan 64 is 401, Jan 74 is 421, Jan 84 is 441, Jan 94 is 461, Jan 04 is 481.
First # = year, second and third # = month, with a decade code added. The decade code added has to change by 20 because there are 12 months in a year. 1/1968 =801, 12/1968 812. 1970 to 1979 the month digits are 21 to 32. Bosch also ads quarterly digits (3 month period). Jan-Mar 68 813 Apr-Jun 814 July-Sep 815 Oct-Dec 816. Jan-Mar 78 833, etc.
Please enter the E-Nr (model number) of your Bosch appliance to get access to all product-specific information and support options. If you are having trouble finding this number, you can use the rating plate finder for further assistance. So your tool serial number should look something like this: 'F52BD1448 1267'. The numbers we are concered with are '1448'. According to the rep at Milwaukee, the '14' stands for the year, which is 2014. The '48' stands for the week in that year that it was made. So this tool was made the last week in November.
Again 20 Number jumps for the decade code. Message Board Disclaimer This is a public forum. Messages posted here can be viewed by the public.
