Mechanical Operation
The shredder uses two rotating cutting shafts,
which are driven by an electrical motor to shred
paper.
Electrical Operation
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.
When the shredder is severely loaded down, the
control board will illuminate red and disable the
motor circuit.
Electrical Components
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.
Doorajar, Machine head safety switch - The safety
switch is a normally open micro switch which is
actuated by a trigger located inside ofthe cabinet door.
The switch is normally closed when the door is
closed and when the machine head is installed on the
cabinet.
Paper Sensors - Located in the throat area consist-
ing of two components, the emitter and receiver.
Emitter - The infrared light beam from the light emit-
ting diode issensed by the receiverto activate/deac-
tivate the control board.
Receiver - The receiver is a light activated diode,
which works in conjunction with the emitter to acti-
vate/deactivate the control board.

g Electrical Components
WARNING!
Always disconnect the power cord from receptacle
before making continuity or resistance tests.
Switches
Set meter to read resistance. Check switches for
continuity from common to closed contacts and
ity from common to the open contact.
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 meterto read 20M ohms. Disconnect
thereceiverfromthe controlboard. With thepositive
meter probe on the receiver wire and the negative
meter probe on the receiver wire check for app-
roximately 4.62 Mega ohms under normal room
light. The resistance will increase when blocked.
Reverse the meter leads and
should be read.

Bag Full Flap Switch - The ap switch is a normally
open switch actuated by the bag full ap. When the
shred bag becomes full of shredded material, the
bag full ap is pushed back and power is then
removed from the motor circuit.

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

Disassembly ofthe shredderis describedin thefollowing steps.
Top Housing Removal
WARNING!
Disconnect the unit from the receptacle before performing
any disassembly procedures.
1.Unplug the power cord from the outlet power supply.
2.Open cabinet door and remove the 3 phillip head screws that
secure shredder top cover to cabinet base.
3.Remove the 4 phillip head screws from the back side of the
shredder which secures top cover to cabinet base.
4. Lift top cover. Remove and label the 3 cables from control
panel.
Engine Assy. (Cutting Head Assy.) Removal
1. Remove the six phillip head screws that secure the main pcb
box to the bottom base.
2. Remove pcb box front cover. Unplug and label all wires from
main pcb box.
3. Open cabinet door and remove the four (14 mm) hex nuts and
4. Carefully lift out engine ( cutting head ) assy and place

2. Remove the two 14mm bolts.
3. Remove the two phillips screws from the encoder housing.
4. Remove gearbox cover.
Motor Removal
1. Remove large double drive gear.
2. Remove small double drive gear.
External Cleaning
Make sure you disconnect the shredder from its power source
before cleaning. The cover and cabinet may be cleaned with
a soft cloth moistened with a mild detergent and warm water.
Do not use chemical cleaners or solvents as these may have
a harmful e
ect. Use detergent sparingly to avoid contact with
electronic components.
Inspection
Whenever the cover has been removed for corrective mainte-
nance, visually inspect for defects such as loose screws or
nuts, damaged wire insulation, loose terminals, etc. Correct
any defects before returning the shredder into service.
