1-2 l Introduction

ATTENTION:
Read This So No One Gets Hurt
We design equipment with the user’s safety in mind. You can avoid the potential hazards
identified on this machine by following the procedures outlined below and elsewhere in the
User Guide.
Introduction l 1-3
1
Introduction
WARNING: Improper installation, operation, or servic-
ing may result in equipment damage or personal
injury.
This equipment should be installed, adjusted, and serviced by qualified technical
personnel who are familiar with the construction, operation, and potential hazards
of this type of machine.
All wiring, disconnects, and fuses should be installed by qualified electrical techni-
cians in accordance with electrical codes in your region. Always maintain a safe
ground. Do not operate the equipment at power levels other than what is specified
on the machine serial tag and data plate.
WARNING: Voltage hazard
This equipment is powered by single-phase alternating current, as specified on
the machine serial tag and data plate.
A properly sized conductive ground wire from the incoming power supply must be
connected to the chassis ground terminal inside the electrical enclosure. Improper
grounding can result in severe personal injury and erratic machine operation. (120
Volt units come with a grounded plug. Must be plugged into a grounded out.)
Always disconnect and lock out the incoming main power source before opening
the electrical enclosure or performing non-standard operating procedures, such as
routine maintenance. Only qualified personnel should perform troubleshooting pro-
cedures that require access to the electrical enclosure while power is on.
CAUTION: Mix blade hazard
There are two hazards associated with the mix blades. First, the blades are driven
with substantial torque. Never place your hand in the mix chamber unless power
is completely disconnected. Second, the mix blades may become razor sharp.
Always be careful when touching or cleaning these blades. Check for sharp edges
frequently. Replace blade if a hazard exists.
CAUTION: Vertical valve hazard
Vertical valves in hoppers slam closed without warning. They will injure your fin-
gers. Always keep fingers clear of valve openings. Never use your fingers to clear
an obstruction. Never use your fingers to move a sticking valve.
(Continued)

1-4 l Introduction
CAUTION: Slide gate hazard
Never use your fingers to move a sticking slide gate under the mix chamber.
CAUTION: Misuse hazard
This blender must be exclusively used for metering and mixing free-flowing (as per DIN
ISO 3435) plastic granulate and additives. A total of four to six different materials can be
metered and mixed in the blender, depending on model.
The following must not be metered and mixed:
Foods of all types (unit does not meet hygienic standards).
Highly abrasive materials, such as stones, sand (increased wear of unit components).
Poorly free flowing, sticky materials (airtight seal by the pneumatic cylinder is adversely
affected).
Liquids and powders (airtight seal by the pneumatic cylinder is not possible).

Included Safety Features
Safety Interlock Switch
The access door is equipped with a safety interlock switch that prevents the mix motor
from running and the slide valves from operating. Do NOT defeat this safety switch.
Hopper Finger Guards
Finger guards are fitted into each hopper compartment. Do NOT reach through these
guards. Do NOT use your fingers to clear an obstruction below these guards. Do NOT
remove these guards.
