Lockout Procedure
mWARNING
Always follow the lockout procedure
before opening any guard! Failure to lock
out the power disconnect switch could
result in accidental start-up and serious
injury!
1. If the machine is running, push the
impeller stop button (1).The impeller,
feed screw, and agitator motors will stop
immediately.
2. Turn the disconnect switch handle (2)
on the electrical enclosure o󰀨 and lock
out. Use the padlock (3) attached to the
enclosure to lock the switch, or lock the
switch according to your plant policy on
energy lockout procedures.
3. Verify that the machine will not start.
If the emergency stop button (4) was
pushed, rotate and pull out to reset. After
rotating parts have stopped, press the
impeller start button (5) and hold for 2
seconds. The impeller motor should not
start.
Press the feed screw start button (6)
and hold for 2 seconds. The feed screw
motor should not start.
Press the agitator start button (7)
and hold for 2 seconds. The agitator motor
should not start.

A.2 Addendum
10-11 Safety, Protective Devices: Add the following.
The emergency stop button (1)
provides rapid access to shut down the
machine in an emergency. The starting
circuit will remain interrupted (open) until
the button is reset; rotate and pull out to
reset. The button is monitored by a safety
relay which shuts down the machine if the
button fails.
13-14 Safety, Safety Switch System: A safety monitor (2) is supplied with
the current electrical system. See the entries for pages 46-47 for more
information on changes to the electrical system. The safety switch testing
procedure has not changed.

18 GeneralInformation,Specications: the variable speed motor for the feed
screw shown in the manual is no longer available. A variable frequency
drive (VFD) is used to control the speed of the feed screw motor (1). Feed
screw speed is controlled by a potentiometer (2) located on the front of the
electrical enclosure.
22 General Information, Operating Speeds and Speed Control:
The potentiometer (see the photos above) for the feed screw can be set
from one (minimum) to 10 (maximum), for a speed range of 15.6–78.0 RPM.

28-29 Operation, Start-up, Stopping and Feeding: The following applies to the
current electrical system. If your machine is equipped with a previous version
of the electrical system see the following pages or the machine manual.
Start-up Procedure
1. All foreign objects and product must
be removed from the feed area (1). All
guards must be securely in place.
2. Unlock and remove the padlock (2)
from the disconnect switch handle
(3) located on the electrical enclosure.
If the emergency stop button (4) was
previously pushed, it must be reset; rotate
and pull out to reset.
3. Turn the disconnect switch handle on
(I).
4. Press the impeller start button (5).The
pilot light (6) will illuminate when the
impeller motor starts.
5. Let the impeller reach full operating
speed. Wait about 20 seconds.
NOTICE
The feed screw and agitator cannot be started
until the impeller has reached full operating
speed.
6. Press the feed screw start button (7)
and agitator start button (8).Begin
feeding product into the machine and use
the potentiometer dial (9) to adjust the
speed of the feed screw if necessary. See
the entry for page 30 in this addendum
and Operation, Feeding in the machine
manual for more information.

28-29 Operation, Start-up, Stopping and Feeding (continued): The following applies
to the current electrical system. If your machine is equipped with a previous
version of the electrical system see the following pages or the machine
manual.
Stopping Procedure
mWARNING
Never attempt to open or remove the
guards while the machine is running!
Contact with exposed rotating parts may
cause sever injury such as amputation!
1. When appropriate for the product, ush
the feed area thoroughly with a generous
amount of water before stopping the
machine.
2. Stop feeding product. Allow the product
inside the cutting chamber and hopper to
be cut and discharged. Push the agitator
stop button (1) and the feed screw
stop button (2) when there is no product
remaining in the machine.
3. Push the impeller stop button (3).The
impeller motor will stop.
4. Turn the disconnect switch handle o󰀨
(O). Lock out the handle with the padlock
or in accordance with your plant policy on
energy lock out procedures.
5. If the guards are to be opened, verify
that the machine will not start. Press
the impeller start button (4) and hold for
2 seconds. The impeller motor should not
start.
Press the feed screw start button (5)
and hold for 2 seconds. The feed motor
should not start.
Press the agitator start button (6)
and hold for 2 seconds. The agitator motor
should not start.
Use of the Emergency Stop Button
The emergency stop button (7) provides
rapid access to shut down the machine in an
emergency. It is not intended for use as the
routine stopping method. Stop the machine
with the procedure shown to the left.
If the emergency stop button is pressed,
it must be reset before the machine can be
restarted; rotate and pull out to reset.

AddendumA.6
Manual Page Number Revision
28-29 Operation, Start-up, Stopping and Feeding: The following applies to the
electrical system supplied from approximately October 2009 until September
2018. See the previous pages for the starting and stopping procedures for
the current electrical system.
The top reset button is labeled
MASTER RESET (1). If the emergency
stop button (2) was previously pushed,
the button must be reset in order to start
the machine; rotate and pull out to reset.
Allow the machine to reach full
operating speed, approximately ten
seconds, before feeding product. This
allows the motor for the feed screw to
reach the full programmed speed.

Feeding Method
mDANGER
Never place hands into the feed opening!
The feed area contains a rotating feed
screw and a rotating agitator which can
cause serious injury such as amputation!
IMPORTANT
Do not allow foreign material such as metal,
stone or wood to enter the feed area.
Parts will be damaged and the product
contaminated.
 Thefeedingmethoda󰀨ectsthequality
andcapacityofthenishedproduct.Asteady,
uniform ow of properly sized product from a
conveyor or similar feeding system yields the
best quality and greatest capacity. Dumping
large quantities of product into the feed
opening produces undesirable cuts and can
overload the motor, clog the feed opening, or
jam the cutting unit. Continuous overfeeding
or jamming will also cause premature damage
and failure of machine components.
The potentiometer dial (1) on the
electrical enclosure controls the speed of the
feed screw motor. To increase the feed rate,
turn the dial to the right. To reduce the feed
rate, turn the dial to the left. When the optimal
feed rate is found, look through the window
on the electrical enclosure door and note
the percentage displayed on the motor load
indicator (2). This percentage can be used as
a reference for setting feed rates in the future.
The optimal feed rate may be at less than
100% of full motor load.
Except for an emergency, never start or
stop the machine when the cutting unit is full
of product. This puts a tremendous strain
on the motor, bearings and cutting parts.
In addition, product that is cut before the
machine has reached full operating speed
may be of such poor quality that it must be
discarded.

manual.

AddendumA.8
Manual Page Number Revision
31 Operation, Machine Overload or Jam: The following applies to the current
electrical system. If your machine is equipped with a previous version of the
electrical system see the next page or the machine manual.
Motor Overload
 Ifthemachineshutso󰀨duringoperation,
one of the motors has likely been overloaded.
Maintenancepersonnelshouldrstlocateand
correct the cause of the overload before the
machine is restarted.
If the machine stops, check the yellow
motor overload light (1) on the outside
of the electrical enclosure. The light will
illuminate if the impeller motor, feed screw
motor, or agitator motor has experienced an
overload. If the light is illuminated, press the
reset button (2) and hold for 4-5 seconds.
Start the machine in the normal manner. If the
machineshutso󰀨again,seeMaintenance:
Troubleshooting in the machine manual.
NOTICE
The variable frequency drive (VFD) will
display the error code oL1 or oL2 only if the
feed screw motor has overloaded.
