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
WARNING: Improper installation, operation or
servicing 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 technicians 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 the machine serial tag and
data plate.
WARNING: Voltage hazard
This equipment is powered by three-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.
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 procedures that require access to the
electrical enclosure while power is on.

Function Description
3-2 l Function Description
Function Description
General
The granulator is designed for grinding plastic waste to
for recycling.
The plastic waste should be free from metal parts
and contamination before granulating.
The granulator is controlled by
start/stop controls on a control
panel.
Standard cutter
Open cutter
The plastics waste is feed into the hopper (A) and falls down into the cutter housing, where rotating knives (B) cut the plastics waste against fixed knives (C) to
granulate.
A perforated screen (D) determines the size of the granulate. The screen is located
in the lower section of the cutting chamber and can easily be changed to give the
desired granulate size.
The granulate passes the screen and falls down through the outlet chute/granule bin
(E) to the outlet pipe (F) for onwards transport.
Granulators with an extraction fan are equipped with an extraction blower (G)
which sucks the granulate out to a cyclone (H) for separation of air. On granulator

models with a conveyor, the hopper is equipped with a conveyor belt. The
conveyor can be equipped with a metal detector.
After this, the granulate is ready for re-use in the production machine, or to be
transported to a container for later use.
The granulator is easy to clean, with a folding hopper and also good accessibility
for maintenance. Knives on the staggered rotor are disposable and should be
replaced when necessary. The rotating knives on an open rotor can be re-sharpened. Grinding is done in a special grinding jig. (The jig is not included when the
granulator is delivered, but is a very practical accessory.)
3-4 l Function Description
Safety System
The granulator has a safety system to prevent access to dangerous
components during operation.
The granulator has knives that rotate at high speed. The granulator is
therefore equipped with a safety system to avoid personal
injury.The safety system must not be changed or modified
under any circumstances.
If the safety system of the granulator is changed or
modified, the machine can be dangerous to use,
presenting a serious risk of personal injury.
All care and maintenance to the safety system of the
granulator must be carried out by personnel with the
necessary knowledge.
If the safety system of the granulator is modified in any way,
Conair’s responsibility under the Machinery Directive ceases
to apply.
Only Conair spare parts must be used to replace safety
components.
Emergency Stop
The granulator has an emergency stop on the control panel.
It can also be equipped with extra emergency stops.
The emergency stop is activated by pressing the button. Reset
by turning the button in the direction of the arrow (counterclockwise).
Safety Switch
The granulator has safety switches of the
position switch type with breaking key:
– If a secured position is changed or when a breaking key
is undone,
it will break the current and the granulator stops.
This granulator has 2 safety switches:
1 at the hopper and 1 at the screen box
Check the wiring diagram (Section 9) to see how many safety switches the granulator is
equipped with.

Star Knob
The star knob for the hopper and screen box
is a very important component in the safety
system of the granulator.
It should take such a long time for the knob/screw
to be undone, that the cutter has stopped before the
granulator can be opened.
NOTE: The length of the screw must never be
changed.
NOTE: The screw can not be removed.
The screen is hardened and the knob is permanently attached.
– To change a star knob, please contact Conair.
NOTE: If the star knob is modified in any way,
Conair’s responsibility under the Machinery Directive
ceases to apply.
Before Starting:
The star knobs on the hopper and screen box
must be fully tightened to stop.
The granulate bin should be installed and the door
shut and locked.

Safety Instructions
Conair granulators are designed for granulating injection moulded, blow moulded
and extruded plastic waste.
The specific technical data for this machine, concerning power and perfor-mance
etc. is described in detail in Section 2.
The granulator is equipped with safety switches, which are described in
Section 3.2.
Follow the instructions in this manual to avoid personal injury and damage
to machine components.
Always follow these safety measures when handling the granulator.
• Electrical installation must only be done by a competent
electrician!
• Before the granulator is opened for servicing and maintenance.
Always disconnect the power with both the main switch and
the switch on the granulator.
• Never put any part of your body through the granulator openings, unless both the main switch and the switch on the granulator are in “Off” (0) position.
• Be careful with the knives, they are sharp and can cause personal injury.
• If the rotor must be turned manually – do this with great care!
• Observe care when opening or closing the hopper and screenbox, so as not to trap parts of the body.
• The granulator should not be able to start before the hopper
and screen box are properly closed.
• Never remove protective guards or pipes adjacent to the outlet/granule bin.
• Granulators with belt conveyors! Observe care so that conveyor belts with dogs do not grip clothing, or arms and feet.
• During maintenance, pull out the plug on the distribution box.

Installation
Read through the whole of Section 5 before installing the machine! All instructions
must be followed in the given order to avoid injury or damage.
Be careful with the knives, they are sharp and can cause personal injury.
The granulator must only be connected to the mains by a competent
electrician.
Pre-Start Checks
• The unpainted parts of the machine are protected with oil prior to delivery
and transport Clean the granulator from rust protection agent before it is
used.
• Check the knife clearance and tightening torque on the bolts for the
knives. Refer to installation of knives in Section 7.
Two Hours After First Start
Check the knife clearance again and the tightening torque of the knife retentio
screws. Check the screws for both the fixed and rotating knives.

Installation
Electrical Connection
The granulator should be connected by a competent electrician.
• Connect the granulator to the main power supply. The wiring diagram
indicates the fuse sizes, see Section 9.
• The granulator is delivered with electrical equipment connected for clockwise phase rotation. Check with a phase sequence indicator and connect
the granulator with clockwise phase rotation.
Check the direction of rotation of the granulator motor:
• Make sure that the main switch beneath the control panel is “On” (1).
• Check that the emergency stop is not activated.
• Check that the star knobs on the hopper and screen box locks are fully
tightened to stop.
• Undo and remove the upper panel on the right hand side of the granulator.
• Press “Start”
• Check that the granulator motor rotates in the direction indicated by the
arrow on the cutter pulley.
• Granulator with blower, – check that the direction of rotation of the blower
corresponds with the arrow on the cover.
NOTE: The blower blows even if the direction of rotation is wrong.
• Granulator with conveyor belt, – check the direction of the
conveyor belt.
If any direction of rotation should be incorrect:
• Press the stop button.
• Switch off the main switch.
• Switch two incoming phases.
