MACHINE DESCRIPTION:
This machine is a knife granulator specially designed for thermoplastic materials.
The thermoplastic material to be granulated enters the infeed hopper and falls into the cutting chamber where the
blades cut the material between the rotating and fixed knives. The cut material then drops into the discharge hopper.
Granulated material size depends exclusively on the screen hole size and not on blade design or quantity.
This machine is designed for thermoplastic materials, but can granulate other materials like leather, paper, resin,
rubber, and materials with similar density as thermoplastics. Metals and other similar hard materials cannot be
processed and will severely damage the equipment.
This machine has been designed for long life and heavy duty conditions as long as the machine is correctly used and
maintained.

PRE-INSTALLATION CHECK:
1. Insure the proper electrical voltage supply is provided. Refer to the serial tag on the granulator.
2. With electrical power off and locked out, open the machine completely. Visually inspect the hopper and
screen cradle for any foreign objects.
3. Close machine completely.
4. Remove any foreign objects on or around the unit.
. NOTE: When opening screen cradle, you must clean thoroughly before closing. The screen cradle must
close tightly to the cutting chamber. Failure to clean could result in screen or cradle damage.
CAUTION: Never use iron washers or lock washers. These types of washers are deformed when
tightened and can even break when tightened at the indicated torque.

ELECTRICAL INSTALLATION:
Upon receiving the equipment, verify that the voltage supply corresponds to the data plate as specified for the
granulator.
We recommend installing a disconnect between the power supply and the granulator starter in order to energize the
equipment and to protect the electrical system. Always disconnect the electrical supply before cleaning the machine,
performing maintenance or adjusting blades.
CAUTION: The wrong selection of wire gauge size can cause irreparable damage to the granulator. A
qualified electrician will need to determine the proper wire size based on your application.
CAUTION: Only an experienced electrician should wire the control panel. Wiring by a qualified electrician
must be in accordance with all local and national requirements.
Connect power to the main control panel. Refer to the wiring diagrams that are supplied with your equipment.
VERIFYING ROTATION:
Check the direction of rotation of the motor. Remove the drive side cover. Jog the granulator motor and verify the
rotor pulley is rotating in the correct direction. It is very important to verify the correct rotation of the rotor in the
direction indicated by the arrow located on the drive pulley. If rotation is incorrect, follow proper lock out procedures
and swap any two of the three incoming main power wires.
. NOTE: Do not change other wires in the main enclosure. Change only the power leads if rotation is
incorrect.
The granulator is now ready for operation.

FIRST TIME OPERATION:
Before operating the granulator it is necessary to perform a careful inspection, checking that there are no materials
inside the cutting chamber, especially metallic parts or debris that might have fallen into it during transportation. After
verifying this, spin the rotor manually using the pulley or flywheel as an aid, to check for free spinning. Verify blade
adjustment. (See stationary knife adjustment section in this manual.) Verify that the blade bolts are property torqued.
(See the blade / knife replacement section in this manual.) Close the granulator.
CAUTION: These procedures should be performed with the power turned OFF to avoid injury and
equipment damage.
Connect the power and start up the granulator by pressing the start button.

GRANULATOR OPERATION:
Conair recommends running the granulator for the first time, with low quality material and giving it two or three passes
through the granulator, so that the internal walls of the machine can be cleaned from quantities of rust inhibitor
grease or dust.
Before starting the granulator, make sure that there is no material in the cutting chamber and the pulley can rotate
manually. Once the rotor has reached its maximum speed, you can gradually feed the parts through the feeding
hopper. In case of material overfeeding, the granulator’s overload protection will stop the motor.
The overload is a sustained condition of a higher current than motor rated current on the serial tag. During operation,
current will show very high instant peaks, this will not cause an overload as long as high current is not constant.
When the granulator stops because of an overload, it will be necessary to:
- Disconnect the main power.
- Open the cutting chamber and remove excess material.
- Verify that there are no blown fuses.
- Verify that the overload relay element has been reset.
- Close the granulator, restore power, and start the machine again.
Before the granulator is turned off, allow it to operate several minutes without material, to allow regrind material to
clear the cutting chamber. If you do not perform this step, it will be necessary to manually remove material from the
cutting chamber before starting the granulator again.
It is important to mention that the operator should use caution and avoid allowing metallic parts inside the cutting
chamber since this will cause severe damage to the equipment.
MAINTENANCE:
LUBRICATION:
Do not over grease bearings. This can cause damage to the seal. The frequency of lubrication is in direct proportion
to the hours of actual granulator operation. See suggested lubrication schedule.
HOURS OF AMOUNT LUBRICATION
OPERATION PERIOD IN WEEKS
8 1 OUNCE TO 1/4 OF TUBE 12
16 2 OUNCES AS REQUIRED 6
24 3 OUNCES AS REQUIRED 4
Conair recommends the use of SKFGRA-TM3 grade 3MLGI grease or a type that is compatible.
. NOTE: If grease is protruding from bearing seals you are over greasing. Remove excess grease
protruding out of bearing and extend your lubrication periods.
DRIVE BELTS:
Periodically check the tension of the drive belts. Disconnect and lock out power per standard procedures. To access
the belts, remove the belt guard cover plate and rear sound enclosure. Always maintain proper belt tension and care.
Adjust the motor tensioning bolts in order to tension the drive belts.
SCREEN REMOVAL:
1. Disconnect and lock out power per standard procedures.
2. Remove the discharge bin.
3. Remove the bolts on the screen cradle access door.
4. Remove the screen cradle bolts and lower with caution.
5. Remove screen from cradle and inspect for any wear or damage. Be sure to observe screen orientation as
screen is not reversible. The stamped number on the screen should face you during installation.

7
SCREEN INSTALLATION:
1. Remove all regrind and foreign material from the screen, cradle and its mating surfaces. In order for the
screen to hold firmly in place, the cradle must close without interference.
. NOTE: This is a non- reversible type screen. Screen part number stamp on the edge should face the
front in the screen cradle.
2. Place screen in cradle and lift into place.
3. Install the bolts onto the cradle and tighten. Refer to the torque chart for bolts.
4. Install the screen access door, and bolt in place. Refer to the torque chart for bolts.
5. Close sound hood doors.
6. Install the discharge bin.

8
BLADE / KNIFE SHARPENING:
When the granulator begins to be noisy or when the regrind material starts getting dusty it could mean that the blades
need adjusted and/or sharpened. Disconnect and lock out power per standard procedures. Inspect blade gap and
blade wear. If blades have excessive gap adjust as instructed.
Remove and sharpen blades after checking the condition (if necessary). If metal fragments have accidently fallen into
the granulator and chipped the cutting edges Conair advises blades be replaced as sharpening will not remove traces
of the chipping. The sharpening angles are given on the next page.
When rotor knives are sharpened they must be kept in sets. The sharpened knives within a set are to be within
tolerance of +0.002 to -0.002 from the back edge of the knife to the cutting edge of all knives within a set, one blade
to another.
You will obtain maximum performance from your granulator and minimum amount of dust material in the regrind if the
blades are correctly sharpened, observing the angles shown below. Please note that failure to maintain the proper
angle on the knife edge when sharpening voids all warranties and will diminish the performance of the granulator.

BLADE / KNIFE REPLACEMENT:
1. Disconnect and lock out power per standard procedures.
2. Open sound enclosure doors, if applicable.
3. Remove sound panels from the rear of the machine, if applicable.
4. Open rear cutting chamber door.
5. Make sure the hopper hold down bolts are loosened, swung free from the hopper frame first. Open
hopper using the powered actuator.
6. Remove and discard the bolts that hold down the bed knives.
7. Remove the bed knives.
8. Remove and discard the bolts that are attaching the rotor knives to the rotor.
9. Remove the rotor knives.
10. Loosen bed knife adjusting bolts until the bolt is flush on the back side of bed support.
11. Install the bed knives making them flush on the back side of the bed support. Make sure the bed supports
are clear of foreign material between the bed knife and the surface of the bed support. If not clean, it will
make proper knife adjustments impossible and could cause damage to the knives and cutting chamber.
12. Install new bed knife bolts and slightly tighten.
13. Install rotor knives to the rotor. The surface between standoff and knife must also be clean to insure a firm
fit against the rotor knife and standoff to make a proper adjustment.
14. Install a new rotor knife bolts and torque to 215 ft-lb for 5/8 inch bolts. Install the center knives first then the
outside knives.
15. Proceed to stationary knife adjustment section.
. NOTE: Both rotor and bed knives are installed with grade 8 bolts. It is the recommendation of the
bolt manufacturer that new bolts be installed each time knives are reinstalled. Grade 8 bolts are
marked with a distinctive symbol bearing six grooves engraved on the head.

10
STATIONARY KNIFE ADJUSTMENT:
1. Using a 0.006 up to a 0.010 feeler gauge at the cutting edge of a bed knife, turn the rotor in reverse, by
hand, and turn the set screws until there is a snug fit with the feeler gauge between the cutting edge of the
highest rotor knife tip and the bed knife.
2. Follow the same procedure between all bed.
3. Torque bed knife bolts to 215 ft-lb for 5/8 inch bolts.
4. Recheck the gap between all rotating knives and bed knives.
. NOTE: There will be a slight variation of the gap between some rotor knives and the bed knives.
However, with the tightest gap being 0.006 the variation is acceptable.

OPTIONAL COOLING SYSTEM:
Series TF granulators have bores in the bearing housings (as shown in the illustration below) to allow the air flow created by
the knives to cool the cutting chamber. Additionally the granulator uses cooling water in the inclined plate. The use of cooling
water is not always required. It will depend on the operator experience or if material to be granulated has a low melting
temperature. Needed quantity of water will vary, but standard tap water pressure will usually be enough.
