Mechanical Operation
The shredder uses two rotating cutting shafts,
which are driven by an electrical motor to shred
paper.
Electrical Operation
Bag Full Flap Switch - The flap switch is a normally
open switch actuated by the bag full flap. When the
shred bag becomes full of shredded material, the
bag full flap is pushed back and power is then
removed from the motor circuit.
When the center power on switch is pressed,
all the LED warning symbols on the indicator
The shredder will now
be in standby mode and the “Power-on” symbol
on the indicator panel will be illuminated amber.
When the shredder is in standby mode and the the
cabinet door is opend,the normally closed door
adjar micro switch is opened and prevents power to
the motor until the door is closed.. When the bag full
sensor is triggered, the bag full icon will illuminate.
The control board will then disable the motor circuit
until the shredder bag is either cleared or emptied.
Paper Sensors - Located in the throat area consisting of two components, the emitter and receiver.
When the shredder is severely loaded down, the
control board will illuminate red and disable the
motor circuit.
WARNING!
Always disconnect the power cord from receptacle
before making continuity or resistance tests.
Electrical Components
Switches
Set meter to read resistance. Check switches for
continuity from common to closed contacts and
ity from common to the open contact.
Motor - Thermally protected motor designed for
continous operation.
Capacitor - AC motor run capacitor.
Power on/Auto feed on switch - The Power on
/Auto feed on switch, when depressed, connects
the hot and neutral circuits to electrical components
of the shredder.
Door ajar, Machine head safety switch - The safety
switch is a normally open micro switch which is
actuated by a trigger located inside of the cabinet door.
The switch is normally closed when the door is
closed and when the machine head is installed on the
cabinet.
Emitter - The infrared light beam from the light emitting diode is sensed by the receiver to activate/deactivate the control board.
Receiver - The receiver is a light activated diode,
which works in conjunction with the emitter to activate/deactivate the control board.
Testing Electrical Components
Emitter - Set meter to the diode setting. Disconnect
emitters from the control board. With the positive
meter probe on the emitter wire and the negative
meter probe on the black-stripped emitter wire,
check for approximately .639 ohms. Reverse the
meter leads and
should be read.
Receiver - Set meter to read 20M ohms. Disconnect
the receiver from the control board. With the positive
meter probe on the receiver wire and the negative
meter probe on the receiver wire check for approximately 4.62 Mega ohms under normal room
light. The resistance will increase when blocked.
should be read.

General Troubleshooting
Troubleshooting Chart
Malfunction corrections are based on visual observations made by the operator. The causes of the
malfunctions are isolated by the symptom of the
malfunction and noting at which point in the operating cycle the malfunction occurred. Malfunctions
may be pinpointed to a defective electrical component or mechanical part by referring to the
Principles of Operation, the troubleshooting guide
and the wiring diagram.
The troubleshooting guide chart that follows is
arranged in order of the normal operational
sequence. When a malfunction occurs, read down
the approprithe SYMPTOM column until you
ate description for your symptom. Read the corresponding PROBABLE CAUSE, then perform the
recommended procedure in the CORRECTIVE
ACTION column. When replacing electrical components that have push on terminals, label the electrical leads that were removed, to facilitate reconnect
ing them. Refer to the wiring diagram on page 6
to resolve any wiring di culties that may occur.
WARNING!
Always unplug the shredder to avoid possible electrical shock hazard before attempting to perform
any repairs.
