Figure 19: Electrical Safety Interlock Switch (Located on mixer door)
A unique electric safety switch is used to shut off power to the blender any time
the mixer door is opened. Do not alter or tamper with this switch in any way.
Always disconnect and lockout all electrical power and pneumatic (i.e.
compressed air) sources prior to servicing or cleaning the Slide Gate/Auger
Blender. Failure to do so may result in serious injury. No one but the person
who installed the lockout may remove it.
