“Service Instructions”
with supporting pictorial diagrams for added clarity
WARNING
1. Check the machine RATING PLATE DETAILS are compatible with the electrical mains supply.
2. Disconnect the electrical mains supply before removing any covers.
3. The machine MUST
NOTE: THE ELECTRIC MOTOR IS PROTECTED BY AN AUTOMATIC THERMAL OVERLOAD CUT-OUT
Product Testing after Servicing or Repair.
IMPORTANT. If any electrical component has been changed, an electrical connection broken and
remade, or any wiring disturbed, the product being repaired or serviced must be flash tested or PAT
tested. This test must be carried before a product is handed back or returned to the customer or
returned to stock. The test must be appropriate for the machine being repaired. E.g. double insulated
or earthed. A competent person should conduct the test and keep a log of all machines tested, the
serial number of the machine, the details of the test, the test results and the date the test was carried
out.
- For each machine give full details of the replacement part numbers
- For each machine give the recommended servicing procedure
have a sound Electrical Earth Connection.

INSTALLATION NOTES
POWER SUPPLY
Check that the details marked on the machine rating plate conform with the electrical mains supply.
Single phase power supply operation - 115v. 1ph. 60Hz
240v. 1ph. 50Hz
This machine must be earthed.
SAFETY PRECAUTIONS
1. Before ‘testing’ or ‘using’ the machine, the locking castor wheels MUST be securely locked in the
LOCKED POSITION; this is achieved by depressing the locking levers on the two castor wheels
at the front of the machine. When the castor wheels are securely locked the machine is prevented
from moving on the floor in the event of the paper cutters becoming jammed.
2. DISCONNECT the electrical mains supply plug from its socket before commencing any services.
3. PAT TEST after any servicing.
NOTE: THE ELECTRIC MOTOR IS PROTECTED BY AN AUTOMATIC OVERLOAD CUTOUT.

LUBRICATION OF CUTTING HEAD
To avoid a build-up of paper dust, the cutting head should be cleaned thoroughly on a regular basis
followed by the application of a small amount of shredder oil to lubricate the cutters. Oil penetration
can be assisted by running the machine in reverse and forward modes alternatively.
When the machine is used regularly it is recommended that cleaning and oiling is carried out at
weekly intervals.
At six monthly intervals chains, sprockets and gears should be cleaned and re-coated with Rexel
Shredder Oil.

de-jam plate, gearbox cover and tie rods. Lift away the side plate and gearbox assembly.
(Fig 6)
3. Remove the circlip securing the gearbox and withdraw the gearbox from the side frame.
Retain the de-jam plate.
4. On separation of the gearbox, part of the gear train may remain in the gearbox position.
Remove the gears and clean gearbox cover.
NOTE: Examine the shaft bearings and 1/1 gears for wear and replace if required.
5. Should the gears have become dislodged from the replacement gearbox position the
centre dowel gear as shown (fig. 7) into drive pulley, locate the centre dowel and engage
assembled 1st stage gear. Pack with LM2 grease. Engage the assembled 2nd stage
planet gear carrier with the 1st stage drive gear.
Restrain the gear carrier and rotate the drive pulley to seat the gears.
6. Align the de-jam plate with the gear casing and secure with the new circlip to the side
frame.
7. Offer the side frame assembly to the gearbox cover and rotate the drive pulley to locate
the gears.

SERVICE INSTRUCTIONS
ELECTRONIC ADJUSTMENTS (REED SWITCHES)
Two sensors are mounted on the printed circuit board (PCB) 91, fig.11), each of which
comprise a coil supported on a terminal block and encircling a reed switch. One sensor
detects the high current present in the event of a phase failure, the other detecting the high
current drawn when the motor stalls due to the jamming of the cutting head. The magnetic
field from the coils operates the reed switches that form part of the logic circuit controlling the
contactors which directly switch the motor. (Warning: the glass encapsulated reed switch is
fragile). In the event of a phase failure, the machine will cease to operate, and the control
‘STOP’ button will illuminate.
When jamming occurs, after a short pause, the motor will automatically reverse momentarily
and then stop, the unshredded paper having been returned to the feed chute. The
illuminated controls will now indicate the ‘STOP’ mode. Manual reverse can be obtained by
pressing the reverse button on the control panel to give momentary reverse and then stop.
The waste container door is linked to a safety switch which is connected in the logic circuit
and when open also reverts the machine to the ‘[STOP’ mode. This condition is indicated by
an illumination on the switch control panel/
A ‘Fail-Safe’ circuit is incorporated within the logic circuit to detect any interruption in the
power supply which causes the machine to suddenly cease working. When the power
supply is restored the machine will automatically be re-set into the ‘STOP’ mode.
Machine not cutting required number of sheets
to establish whether the fault is mechanical or electrical both sensors on the PCB should be
temporarily short circuited as in fig.10. The machine should now be checked on mechanical
setting for maximum number of sheets cut and, if satisfactory, will indicate that the fault is
electronic, and adjustment is required. During the test avoid stalling the motor for a
prolonged period. If the maximum cut is not satisfactory, the problem is mechanical.
Adjustment
Revert the sensor connections to the original circuit before proceeding. Correct adjustment is
attained by slackening the terminal block securing screw(1,fig 11) and slightly rotating the
block to adjust the position of the coil relative to the reed switch (2, fig 11). Adjustment of the
coil towards either end of the switch will increase the quantity of sheets cut. Returning the
coil towards the centre decreases the quantity. When the coil is set, tighten the terminal
block securing screw.
This is the only adjustment on the PCB, should any other problems be encountered with the
electronics the complete PCB should be replaced.

The sensor is mounted on the printed circuit board (PCB) (fig 11b) and detects the high
current drawn when the motor stalls due to the cutting head jamming. The magnetic field of
the wire passing through the coil is sensed by the coil and operates the potentiometer, which
forms part of the logic circuit controlling the contactors which switch the motor.
When jamming occurs, after a short pause, the motor will automatically reverse momentarily
and then stop; the unshredded paper having been returned to the feed chute. The
illuminated controls will now indicate the “STOP” mode. Manual reverse can be obtained by
pressing the reverse button on the control panel to give momentary reverse and then stop.
The waste container door is linked to a safety switch which is connected in the logic circuit
and when open also reverts the machine to the “STOP” mode. This condition is indicated by
an illuminated on the switch control panel.
A “Fail-Safe” circuit is incorporated within the logic circuit, to detect any interruption in the
power supply that may cause the machine to suddenly cease working. When the power
supply is restored the machine will automatically be reset into the “STOP” mode.
Machine Not Cutting the Required Number of Sheets
Each machine is set at the factory to achieve the cutting of the maximum number of sheets.
The electrical control is achieved by setting the potentiometer on the PCB (fig 11b). The
electrical setting is checked using the 2-pin test plug located by the potentiometer and
checking the electrical resistance (ohms); compare the value with the factory setting value.
N.B. The setting screw located on the top of the potentiometer is used to achieve adjustment
if necessary. Turning the screw clockwise will increase the maximum number of sheets cut.
Should any other problems be encountered with the electronics, the complete PCB should be
replaced.
