Introduzione

This guide will provide a detailed step-by-step instructions on how to replace the Speed/Motor Control Assembly for the Commercial 8 qt. mixer.

Cosa ti serve

    • Before starting ANY repair/disassembly of the mixer, make sure it is fully unplugged from the electrical outlet.

    • If this mixer is being used in a commercial environment, a LOTO tag can be affixed via the hole on one of the prongs on the mains plug to prevent accidental activation.

    • The speed/motor control assembly contains capacitors which can retain their charge for an indefinite amount of time. These capacitors can present a significant and potentially fatal shock hazard.
