The Avantco 177MX20GRNDR is a meat grinder attachment designed for mixers equipped with a #12 hub.

Installation
To mount the attachment to your mixer:

Cleaning & Maintenance
For sanitary operation, clean the unit immediately after use or before switching food products:
- Safety: Wear hand protection.
- Washing: Wash all components by hand using a mild soap and water solution. Use a long-handled scrub brush on plate units to avoid cutting fingers.
