Enter the number from your machine's serial plate — just the machine number is fine (e.g. 5834). It's on the left-hand side of the cross rail. Don't know your serial? Read our identification guide.

We couldn't parse that serial number.

Try entering just the machine number — the digits before the dash (e.g. 5834). If you're still having trouble, call us at +1-847-427-9360.

How to Read Your Serial Number

The serial number on a W&B machine has two parts separated by a dash or slash.

5834 - 2
5834
Machine number
Determines the series
- 2
Build suffix
Identifies configuration batch

The machine number (left of the dash) places your machine in a series. Use that series to find the right manual. The suffix is important when ordering parts — always include it.

Where to find it: The serial number plate is on the left-hand side of the cross rail, recessed above the lower way surface. If the stamp is worn down, try removing the center cap on the turret — it may also be stamped underneath. Some machines also have it on a plate or plaque attached to the machine.
