1-4 Warnings and Precautions
Our granulators are designed to provide safe and reliable operation when installed and operated within design specifications, following national and local safety codes.
To avoid possible personal injury or equipment damage when installing, operating, or maintaining this granulator, use good judgment and follow these safe practices:
˛ LEARN AND OBEY your company’s safety policy regarding granulating
equipment.
˛ MOVING OR LIFTING THE GRANULATOR: Although our equipment is built
and engineered for great ruggedness in operation, care must be taken when moving the machine along the floor or lifting it. Damage may occur to sheet metal covers, electrical cabinets, or small brackets if pressure is applied to them when moving the granulator. When lifting the granulator, be certain of total machine weight and the capability of the lifting equipment. (See the Granulator Specification Sheets for machine weights and dimensions.)
˛ GRANULATOR LOCATION: Adequate area for routine maintenance should be
provided in order to open the machine for knife, screen, or cleanout service. Proper service area clearances also should allow people who are working on the machine to be clearly visible to others, thereby reducing the potential safety hazards.
˛ SAFE HOUSEKEEPING: The work area must be kept clean and uncluttered during
periods of operation or maintenance. No hand tools or other metal objects should be left on or around the machine. Any tools or other metal objects that mistakenly fall into the hopper feed opening can cause severe damage to internal cutting chamber, rotor and screen components.
˛ SAFETY GLASSES OR A FACE SHIELD MUST ALWAYS BE WORN when
servicing or operating the machine. Although our machines are designed for the maximum in flyback control, caution must be used when operating near the hopper feed opening in order to guard against unexpected material flyback.
˛ EAR PROTECTION may be required when operating the machine during
granulation of very hard or noisy materials. The Occupational Safety and Health Act of 1970 has established guidelines for Permissible Noise Exposures (OSHA 1910.95) that should be followed.
˛ NEVER attempt to operate the granulator unless it is fully assembled with all guards
and interlocks in place and functional.
˛ OBSERVE all danger, warning, caution and safety labels on the equipment.
˛ Upon completion of any machine maintenance, be certain ALL SAFETY GUARDS
AND COVERS are securely and properly fastened prior to resuming machine operation. All fasteners must be in place and properly tightened. ANY
SHORTCUTS MAY RESULT IN INJURY TO PERSONNEL OR DAMAGE TO EQUIPMENT.
˛ NEVER wear any loose fitting clothes, neckties, or dangling items such as earrings,
belts, or shoestrings. Jewelry, such as wristwatches, bracelets, or rings should NEVER be worn. Long hair must be tied back or placed in a tight fitting hairnet. NEVER lean against or rest hands or feet on the granulator when it is in operation or open for maintenance. NEVER stand on the granulator when it is in operation.
˛ ROTATION OF MOTORS: The correct rotating direction for the granulator motor
is clearly marked on the machine. Always check for proper rotation of motors. Incorrect rotation direction can cause severe damage.
˛ ELECTRICAL GROUNDING: All electrical equipment on the granulator must be
grounded in accordance to all local codes and Article 250 of the National Electric Code.
˛ ALWAYS DISCONNECT AND LOCKOUT the main electrical power to the
granulator before performing any service.
˛ SAFETY INTERLOCKS MUST NOT BE BYPASSED. The mechanical and
electrical safety interlocks ensure the safety of personnel. They should never be tampered with or removed for ANY reason. They should be checked frequently by a qualified mechanic for proper operation.
˛ NEVER modify the machine configuration or any individual component without
written notice from the factory.

Chapter 2: Functional Description
2-1 Models Covered in This Manual
This manual provides the necessary instructions for the installation, set-up, and maintenance of our auger-fed granulators.
2-2 General Description
The auger-fed granulator is a gravity-loaded, auger-hopper-fed, medium-duty, plastic material cutting unit. The granulator is fully portable and automatic, with a small footprint. It is designed for continuous, medium-duty applications, such as runners, sprues, blow-molded scrap, small thin wall parts, and pre-cut thermoformed web.
2-3 Typical Features and Components
Infeed
The auger and trough assembly is constructed with the throat opening and an independently chain-driven auger for the transfer from process machine to the cutting chamber of irregular shapes of plastic material. A removable trough cleanout cover is provided to fully expose the auger for maintenance purposes.
Cutting Chamber
The cutting chamber consists of a belt-driven three-blade rotor and two adjustable bed knives. A lockable, hinged viewport allows viewing of the introduction of material to the cutting chamber from the auger, the clearing of obstructions, or for other maintenance purposes.
The final granulate size is determined by the hole size of the screen selected. This screen, an interchangeable feature of the screen drawer assembly, is located between the cutting chamber and the discharge chute.
Drive System
The drive units consist of an electric motor with drive belts for the cutting chamber, an electric motor and gear reducer with drive chain for the auger feed, and safety interlocks. Unless otherwise specified, the motors are provided with separate controls wired for a common power supply.
Discharge System
A removable discharge chute, located beneath the base, is designed with a take-off tube or connection to a customer-provided, continuous-running unloading system. A pneumatic evacuation system is also available.
Base
The base is caster-mounted, with four swivel casters (two locking casters) for easy positioning.
2-4 Safety Features
Safety Switches
The cutting chamber viewport, auger infeed opening, and the screen drawer assemblies are safety interlocked to allow the auger and the rotation of the rotor to completely stop before physical access to the cutting chamber can be made. Unthreading the mechanical interlock disengages an electric limit switch, which in turn disengages the rotor and auger drive motors. The period of time required to fully unthread the mechanical interlock allows the auger and rotor rotation to stop. Removal of the auger infeed opening shipping cover or customer supplied auger trough safety guard will also disengage an electric limit switch, which also disengages the rotor and auger drive motors.
For safety purposes, the machine should be disconnected from the power lines by a disconnect switch or by removing the plug from its receptacle. Check all safety switches periodically for proper operation. See Figure 1 for location of the safety switches.
Safety Tags
A set of metal plates is attached to the machine to warn of potential danger.

Chapter 3: Installation
3-1 Uncrating the Equipment
The granulators are shipped mounted on a wooden skid, then blocked and banded to prevent movement. All non-painted items subject to corrosion are coated with a quality rust preventative and the machine is then covered with heavy-duty polyethylene to protect it from moisture and dirt. Refer to the Appendix for detailed dimensional data and pertinent weights.
Prepare in advance the site you have selected for installation of the granulator. Be certain that the area to be occupied by the machine is clean, level, and free of obstructions. The machine should be set on a concrete floor, and care must be taken when moving the machine across a hollow timber floor, so that the point loading of the casters does not cause damage. The site you have selected must have a floor rating to adequately support the weight of the machine. If necessary, use steel shims to level the machine.
Locate the machine so that access is given to electrical components, screen, and hopper. Maintenance personnel should have unobstructed access to the units on which they will be working.
To avoid squeezing people working near a machine, there should be adequate clearance maintained between machines, walls, or partitions. Hinged doors and covers should have full swing. Restrictions may force work in cramped quarters. An off-balance operator with an awkward reach into a partially obscured area is unsafe.
If inspection after shipment has revealed no shipping damage, unpack the unit by removing all hold-downs, tie-downs, bolts, nuts, etc. Remove the envelope with the electrical schematics and instruction manual from the base evacuation area.
You can now have the machine lifted from the skid. To lift and move the granulator safely and correctly, cover any sharp corners or edges, and use the type of equipment that has the most appropriate features and capacity. Use the designated lifting points, and do NOT lift the machine by the hopper handles or guards.
3-2 Installing the Safety Switches
Auger granulators are designed and intended for use under the mold of your injection molding machine. Do not use this equipment for any other applications without consulting the factory with application details for specific recommendations on guarding and safety.
Control Panel. An open contact is provided on the terminal strip in the granulator control panel. These terminals are provided for customer wiring to an interlock switch installed on the molding machine safety gate so the auger will stop when the gate is opened.
Feed Chute. An interlock switch is furnished at the auger infeed opening. This switch must be satisfied by a customer-furnished feed chute. This feed chute must be designed in such a fashion that will totally prohibit access to the auger by reaching uner, around, over, and through molding machine guards. If you would like us to quote a suitable feed chute, please furnish dimensions of the molding machine.
Safety Plug. Each auger granulator is furnished with a “safety plug” receptacle installed at the feed end of the auger. The mating plug for the receptacle is shipped separately from the granulator. This plug is provided with a one foot chain, the end of which must be permanently affixed to the molding machine, positioned so that it can be plugged into the receptacle only when the auger is in its intended position under the mold. Removal of the granulator from its intended position must require removal of the safety plug, whicih will deactivate the control circuite. The safety chain must also be affixed in the same manner when the auger is used with conveyors, separators, or other feed systems.
Emergency Stop. Access to the emergency stop buttons at the end of the auger and the top of the electrical panel must not be restricted in any way. Relocation of the switch is recommended if necessary to avoid any restrictions. Please consult the factory with installation details for specific recommendations.
3-3 Electrical Connections
Check serial tag voltage/amperage requirements and make sure your electrical service conforms before making any electrical connections. Make sure that all three phases are wired correctly.
Bring properly sized power leads and grounds from a fused disconnect to the unit. Provide external overcurrent protection to the unit, using circuit breakers or fuses. If you use fuses, make sure that they are dual-element, time-delay fuses, sized according to your electrical code. Refer to the technical specifications in the Appendix for horsepower, voltage, phase, and frequency requirements to determine the size and rating of the supply cable required.
Carefully check the diagrams packed with the machine. All internal wiring has been done at the factory. All safety interlocks have been verified to be functional before shipment. Run line power conductors to the control enclosure per local and National Electrical Code requirements. Terminate the power conductors at the control enclosure disconnect switch line terminals.
Use the following procedure to complete the electrical connections:
1. Check to be certain that the starter heater elements correspond with the motor
requirements. If controls are not supplied, the limit switches supplied on the machine must be wired into the circuit at the common terminal box.
2. Check that the limit switches are closed.
3. Turn switch ON at main power supply.
4. Jog motor by pressing the START and then the OFF button. This starts and stops the
motor.
5. With the electrical power ON, check that the motor rotates in a clockwise direction at
the viewing port in the belt guard. If motor rotation is correct, continue to the next step. If rotation is incorrect, complete the following procedure:
a. Shut power OFF and disconnect incoming power supply.
b. Reverse any two of the three power line connections to the machine.
c. Re-connect the incoming power supply line and turn ON the main power
switch to recheck motor drive rotation.
6. If Airveying system (optional) is fitted, press the Airveyor START button, and check
the blower motor rotation. The blower motor should rotate in a counterclockwise direction. If blower motor rotation is correct, continue to step 7. If blower motor rotation is incorrect, complete the following procedure:
a. Shut power OFF and disconnect incoming power supply line.
b. Reverse any two of the three power line connections to the blower motor.
c. Re-connect the incoming power supply line, and recheck the blower motor
rotation.
7. Allow all motors to run up to speed for at least 30 seconds.
3-4 Accessing the Cutting Chamber
You will need to access the cutting chamber before initial startup and for various maintenance procedures.
Use the following procedure to access the cutting chamber:
1. Turn the main power off, remove the line fuses, and tag the machine as out of
service.
2. Unthread the cutting chamber safety interlock.
3. Remove the bolts from the face of the screen drawer, and pull the drawer assembly
out of the cutting chamber.
Note: It may be necessary to manually rotate the rotor to ease the removal and
replacement of the screen drawer.
4. Slide the discharge bin out of the cutting chamber.
3-5 Closing the Cutting Chamber
After completing any maintenance or adjustments inside the cutting chamber, use the following procedure to close the cutting chamber and resume use of the granulator:
1. Slide the discharge bin into the cutting chamber.
2. Push the screen drawer assembly into the cutting chamber and tighten the bolts.
3. Tighten the cutting chamber interlock.
4. Replace line fuses, turn power on, and remove the out of service tag from the
machine.
3-6 Initial Start-up
This machine has been run under power and tested at the factory prior to shipment. The necessary settings and adjustments have been made so that a minimum amount of setting up or re-adjustment is required when starting up the machine in its new location.
With all electrical, mechanical connections and lubrication requirements having been attended to, the following start-up steps should be carefully carried out before attempting to place any material into the infeed hopper. Use the following procedure to prepare the machine for initial start-up:
WARNING! Before operating the granulator, insure that the granulator has been
correctly assembled and wired.
1. Access the cutting chamber as describe in Section 3-4 on page 15.
2. Thoroughly clean the rust preventative materials or grease from the hopper, the inside
of the cutting chamber, knives, rotor, screen, discharge system, and exterior of the machine. Do not use solvent on any of the painted areas, as solvent may damage the paint.
3. Check all rotor knives to make sure they are properly seated on the rotor and securely
fastened. Although they are ground as a set, one knife will probably be .001” to .002” higher than the others. This should be marked and used when adjusting the bed knives for proper clearance.
4. Use a feeler gauge to check the clearance between the rotor and the bed knives by
turning the rotor backwards. Rotating the rotor backwards gives a better feel and does not cut the gauge, should the knives be too close. Check the knives on each end only. Proper clearance is 0.15 mm (0.006”). This clearance is slightly greater at the center of the knives.
Note: Recheck knife clearance after the first 24 to 36 hours of operation.
5. To make the adjustment on the bed knives, the bed knife adjusting screws should be
hand tightened to hold the knife firmly against the knife seat while adjusting the knife forward using push and pull screws. After the clearance is set, torque the screws according to the table in Section 7-3 on page 34.
6. With the exposed parts of the machine thoroughly clean, and all knife clamping bolts
securely fastened, close the cutting chamber as described in Section 3-5 on page 15.
Note: After initial start-up, the rotor knife retaining screws should be checked after 8
hours running to be assured that the proper torque is maintained. Thereafter, rotor knife retaining screws should be checked weekly.
Note: The rotor must be rotated at least two rotations every 30 days to prevent
brinnelling and corrosion of raceways.
Chapter 4: Operation
4-1 Start-up
Before starting the machine, check that the rotor rotates freely by rotating it by hand. Inspect the cutting chamber carefully to insure that nothing has fallen into it. Make sure all screws and bolts are properly secured. Check all electrical connections and motor rotations. See Chapter 3 on pages 12-15 for detailed set-up instructions.
The door-mounted pushbutton controls are arranged from left to right for sequential starting of the system’s motors. Allow all motors to run up to speed for at least 30 seconds.
WARNING! The cutting chamber knives are extremely sharp. Always wear heavy gloves
and exercise care when working in the cutting chamber.
4-2 Feeding the Granulator
Feed the granulator through the opening in the hopper. The method of feeding the granulator depends on the physical form and nature of the material being processed.
For maximum efficiency, the granulator should be fed at a rate that is consistent with its capacity; i.e., if the granulator is rated at 60 kg/hr (132 lbs./hr.), then the general feed rate is 1 kb/min. (2.2 lbs./min.). Under these operating conditions, the correct proportions of cut and uncut particles will be present in the cutting chamber.
WARNING! Under no circumstances should the operator attempt to reach into the
hopper to dislodge any bridged or jammed material while the granulator is in operation. To clear the hopper of bridged or jammed material, the machine main power must be turned off and the machine isolated.
4-3 Clearing a Jammed Cutting Chamber
Never attempt to free a jammed machine by placing hands on the rotor, rotor knives, or inside the cutting chamber. Hands must be kept clear of the rotational path of the rotor knives.
Good footing on a clean floor is essential and the body should be well braced to guard against loss of balance should the jam suddenly come free. Use the following procedure to clear a jammed cutting chamber:
1. Disconnect and lock out power.
2. Be certain that the rotor is motionless.
3. Access the cutting chamber as describe in Section 3-4 on page 15.
4. Use a pry bar to exert force on the rotor, usually in the direction opposite normal
rotation. A leather mallet and a block of wood of sufficient length to keep hands away from path of knives can be used if necessary.
5. Use pliers to remove material from the cutting chamber, keeping in mind that the
removal of material may cause rotation of the rotor and rotor knives.
6. After clearing the jam, be certain that the screen and all guards and covers are
secured in place before connecting power and starting the machine.
4-4 Shut-down
Use the following procedure to properly and safely shut down the machine:
1. Stop all feeding of material.
2. Allow the granulator to run at least three minutes until the cutting chamber is
completely empty.
3. Press the drive motor “stop” button. This shuts off the rotor drive motor.
4. After the granulator has stopped, press the airveyor stop button (if applicable) located
at the blower motor.
5. Turn the main power switch to off.
Note: For emergency machine stops, feedstock must be cleaned out of the hopper and
cutting chamber prior to restarting the machine.

Monthly
5-2 Testing the Interlock Switch
The cutting chamber interlock switch ensures that the granulator cannot be running when the hopper or screen cradle are open. When disengaged, the interlock opens the electrical control circuit to the motor and prevent the machine from running.
To test the interlock switch, unscrew the cutting chamber interlock screw while the granulator is on. The granulator should stop. If the granulator does not stop, the interlock is not working. If the interlock does not work, the complete mechanism, including the switch, must be removed and disassembled to determine the cause of the malfunction.
5-3 Cleaning the Granulator
Always exercise extreme caution when cleaning the machine to change color or material types.
DANGER! Always disconnect power before servicing.
Clean the auger, auger trough and hopper, cutting chamber, and discharge chute using a clean, stiff brush and vacuum air.
WARNING! Never wipe the cutting chamber clean with your hands.
Never allow foreign material such as metal, stone, or lint into the auger trough and hopper or cutting chamber, as it may cause serious damage to the cutting unit and/or contaminate the granulate making it unusable.
5-4 Removing the Auger
Use the following procedure to remove the granulator auger:
7. Turn the main power off, remove the line fuses, and tag the machine as out of
service.
8. Remove the drive belt guard, drive chain and chain sprocket from the drive end of the
auger shaft.
9. Unbolt the end plate from the trough and pull the auger from the assembly.
Caution! Support the auger during withdrawal to prevent it from dragging on and
excessively scoring the flight edges and/or the trough bar.
5-5 Removing the Rotor
Use the following procedure to remove the granulator rotor:
WARNING! Remove all of the rotor knives before removing the rotor assembly.
1. Turn the main power off, remove the line fuses, and tag the machine as out of
service.
2. Remove the drive belt guard, drive chain and chain sprocket from the drive end of the
auger shaft.
3. Remove the rotor drive belt and sheave.
4. Unbolt the rotor access plate.
5. Remove the rotor from the cutting chamber.
5-6 Lubrication Requirements
All granulator and motor bearings are shipped pre-lubricated from the factory.
The bearings used require a high quality, lithium-based EP (extreme pressure) type of grease, which conforms to the NGLI Grade 2 consistency. This grease has been chosen due to its suitability for use in heavy-duty applications under heavy shock loads. It also contains rust inhibitors, has high temperature stability, and exhibits good water resistance. For normal operating conditions, the grease should be free of any chemical impurities such as free acid or free alkali, dust, rust, metal particles, or abrasives.
Bearings must be re-lubricated periodically to assure long life. The length of intervals between greasing depends on the running speed and atmospheric conditions. See Figure 2 to determine the proper greasing interval.
For best results, bearings should be re-lubricated while in operation. The grease should be pumped in slowly until a slight bead forms around the seals. This bead, in addition to acting as an indicator of adequate re-lubrication, provides additional protection against the entry of foreign matter.
By the time the slight grease bead is formed, it will be noted that the temperature rise is approximately 30ºF. If necessary to re-lubricate while the bearing is idle, refer to the re­lubrication table in Figure 3 for the maximum grease capacity for various sizes of bearings. Bearings should be lubricated with care. Too much grease applied to the bearings at one time can rupture bearing seals.
Grease in bearings prevents excessive wear of parts, protects ball races and balls fro corrosion, and aids in heat dissipation within the bearing. The motors should be lubricated to their manufacturers specifications.

5-7 Adjusting Belt Tension
Belts should be checked on a weekly basis for nicks, cuts, tension, or excessive wear. Any belt of a multi-belt system showing damage or excessive wear should be replaced with a belt of equal strength and size. For best results, replace belts in matched sets.
For continuous reliable operation of the granulator, it is important that the belt tension is correct. Correct tension reduces wear on rotor and motor bearings and keeps belt slip to a minimum. Figure 4 gives the recommended force to deflect each belt by an amount equal to the belt span divided by 64. A gauge is available through the sales department to measure the deflection and force. Use the following procedure to adjust the belt tension:
1. Turn off the granulator at the main isolator switch and remove fuses.
2. Remove the cover to gain access to the belts.
3. Turn the adjusting screw on the motor slide base to tension the belts as required (See
Figure 4).
4. Re-tighten the screws, making sure the pulleys are in correct alignment.
5. Replace the covers.

5-8 Replacing and Adjusting the Knives
The rotor and bed knives are subjected to severe conditions, and you should inspect knives periodically for sharpness. The sharper the knives are kept, the better the machine operates, producing quality regrind. If the knives become severely rounded, chipped, or otherwise damaged, the granulator experiences heavy shock loads during operation causing additional and significant reduction in knife life.
WARNING! Exercise extreme care when rotating the rotor and handling knives.
All flange-type bearings are centered, drilled, and pinned at assembly of the unit. Should it become necessary to replace these bearings, it will be the customer’s responsibility to center, drill, and pin the bearing in position.
Rotor Knives
We recommend that the rotor knife screws be replaced with new screws every sixth knife change to reduce the risk of screw failure due to overstretching. Screws must be replaced with the type specified in the spare parts list. Use the following procedure to replace or adjust the rotor combs:
Caution! Rotor knives should be changed one seat at a time to prevent rotor from
being rotated in an out-of-balance condition.
1. Access the cutting chamber as directed in Section 3-4 on page 15.
2. Set back the bed knives to clear the rotor knives so that the rotor can revolve freely.
3. Carefully block the rotor with a piece of wood to prevent it from turning.
4. Loosen and remove the rotor knife screws (See Figure 5 on page 24) and carefully
remove all rotor knives. Make sure you have solid footing while you apply the breaking force.
5. Thoroughly clean the knife seats with a stone or other non-marring tool, and wipe the
screws with a lightly oiled cloth. Do not leave an oil film on the screws, as lubrication can adversely affect the stress on a screw installed to a fixed torque value.
6. Re-install the rotor knives onto the rotor.
7. Lightly tighten the screws and check that a 0.03 mm (0.0015”) feeler gauge will not
pass between the back of the knife and the knife seat. Tap the knife gently with a rawhide hammer if necessary to close the gap.
8. Tighten the screws evenly and torque the screws according to Section 7-3 on page 34.
9. Re-check the gap between the back of the knives and the knife seats. If necessary,
readjust the knives.
6. Adjust the clearance between the bed knives and rotor knives. (See “Bed Knives” on
page 24.)
Bed Knives
Use the following procedure to replace or adjust the bed knives:
1. Access the cutting chamber as directed in Section 3-4 on page 15.
2. Remove the bed knives by unbolting the bed knife bars and dropping the bars and
bed knives from the cutting chamber frame (See Figure 5).
3. Thoroughly clean the knife seats with a stone or other non-marring tool, and wipe the
screws with a lightly oiled cloth. Do not leave an oil film on the screws, as lubrication can adversely affect the stress on a screw installed to a fixed torque value.
4. Install the new or re-sharpened bed knives.
5. Use the adjustment screws (located on the outside surface of the cutting chamber) to
set the knife clearance to 0.15 mm (0.006”). The clearance should be measured with a feeler gauge at the ends of the knife, by rotating the rotor sheave backwards by hand. The clearance is slightly greater at the center of the knives. Check both the upstroke and downstroke knife gaps.
Note: Adjust the knife gradually from end to end. Adjusting one side completely and
then the other side will cause the adjusted side to tip slightly.
6. Tighten all of the mounting screws according to Section 7-3 on page 34, and re-check
the knife gap.
Figure 5: Cutting Chamber Diagram
5-9 Sharpening the Knives
Under normal operating use, the cutting edge of the knives will eventually become dulled, resulting in reduced cutting efficiency. The blunt knives may either be re-ground to restore the cutting edge, or replaced with new knives when regrinding is not possible.
Note: The minimum dimensions given for the rotor knife and bed knife cannot be
combined to produce a cutting combination. For example, a bed knife ground to its minimum dimension cannot be combined with a rotor knife that is also ground to its minimum dimension.
Rotor Knife Sharpening
The rotor knife can be re-sharpened to the diagram below. The three knives must be sharpened to within 0.076 mm (0.003”) of each other. Greater dimensional variations will cause difficulty when setting the knife gap and create other serious complications.
When sharpening, it is not harmful to allow a few small nicks to remain in the cutting edge. Grinding the cutting edge until perfectly clean can sometimes be wasteful.
Do not install rotor knives that are smaller than the minimum dimension shown, because the fasteners that secure these knives will interfere with the cutting circle. If the rotor cannot turn, the bed knives will be damaged.
Use Figure 7 on page 26 to determine the correct type of rotor knife.
Bed Knife Sharpening
Each bed knife is provided with two cutting edges. When the exposed edges become blunt, the knives can be turned and repositioned to present the new cutting edges. When re­sharpening is necessary, refer to the diagram below.
It is not necessary to grind bed knives to the closely matched tolerance of rotor knives. As with rotor knives, small nicks in the cutting edges will not seriously affect knife cutting efficiency. Bed knives smaller than the minimum dimensions shown must be replaced along with the fasteners that secure them.

Chapter 6: Troubleshooting
6-1 Introduction
The utmost in safety precautions should be observed at all times when working on or around the machine and the electrical components. All normal trouble-shooting must be accomplished with the power off, line fuses removed, and with the machine tagged as out of service.
The use of good quality test equipment cannot be over-emphasized when troubleshooting is indicated. Use a good ammeter that can measure at least twice the AC and DC current that can be encountered for the machine. Be sure that the voltmeter has at least minimum impedance of 5,000 OHMS-per-volt on AC and 20,000 OHMS-per-volt on DC scales. Popular combination meters, VOM and VTVM can be selected to provide the necessary functions.
Before making haphazard substitutions and repairs when defective electrical components are malfunctioning, we recommend that you check the associated circuitry and assemblies for other defective devices. It is common to replace the obviously damaged component without actually locating the real cause of the trouble. Such hasty substitutions will only destroy the new component. Refer to wiring diagrams and schematics.
Locating mechanical problems, should they occur, is relatively straightforward. When necessary, refer to the parts catalog section.
