## What does your Model & Serial Tag Do?

---

Your model and serial number is the identifier we use to prepare for service. As every machine is unique and fitment of parts is critical, we like to know exactly what model we are going to be servicing. This helps us stay prepared and it's the reason we fix 99% of units in one trip.

**Model: Model tells us which style unit you have.**  
**Serial: Serial is used to identify useful information about parts.**  
**Manufacture Date: Gives us info pertaining to units age.**
