Section 1
INSTALLATION
When the machine is not in use, the Feed Bed may be withdrawn
and hung on the stowage hooks.
1.3.......Stacker
The Stacker is fitted, by locating the support shafts each side into
the catch plates. Raising the end of the Stacker will allow it to fit. It
may then be lowered into position.
The height adjustment screws on each side may be positioned to
obtain the optimum height. It is recommended that only one screw
at a time (using a 5mm Allen key), is released when adjusting the
Stacker height.
When not in use, the Stacker may be hung on the stowage hooks on
the base of the machine.
With the Stacker removed,the exit guard will drop fully for the best
access to the output shafts.
NOTE...... The machine will not run with the Guards open or with the
Feed Bed removed.
Stacker Installation ....................................................Fig 1.31

INSTALLATION
1.1 .......Guard
The Main Guard is normally opened at the stacker end, and is
pivoted all the way over, until it rests on the feeder. The complete
guard may be removed from the machine by lifting it off it's guides,
as shown in Fig. 1.11
1.2 .......Feed Bed
The Feed Bed slots into position below the feed shaft housing
blocks. When correctly fitted, the Bed will rest flat against the
bottom edge of these blocks. The back of the Bed has to be raised
slightly, so that it can be fitted, and removed, but do not raise it too
high. Ensure that the Bed is fully forward to the stops on both
sides.
The Feed Bed will not fit, if the friction nip wheel ( Fig. 3.11 page 8 )
has been raised or lowered too far. Adjust the wheel accordingly.

Section 2 CONTROLS
2.1 .......Switches
Isolator This is the main switch to isolate the machine from the
power supply.
Motor Switches the drive on or off. If a guard is open, or the
feed bed removed, this switch will not latch. If the
guard is opened while the machine is running, this
switch will trip and stop the machine.
Feed This switch will engage the paper feed drive.
Auto/Man This switch will release the main print shaft, to allow
setting of the numbering heads.
WARNING
NEVER OPERATE THE AUTO / MAN SWITCH WHILST THE
MACHINE IS RUNNING.
Controls .................................................................... Fig 2.11

Section 2CONTROLS
2.2.......Control Knobs
Handwheel. The handwheel is located at the rear of the
machine, and is used when setting-up.
Print position The fine adjust control which gives +7mm or -7mm
( +¼” or -¼” ) of movement to the print position.
The three rings indicate the general position of the
control and clockwise rotation will move the number
down the sheet.
One full revolution moves the print position 1mm
(3/64”) The control may be adjusted whilst the machine
is running.
Platen Pressure & Lock The printing pressure may be adjusted
as follows:-
Fit a 4mm Allen key into the lock and a 5mm Allen key
into the pressure control.
Loosen the lock and turn the pressure control, either
towards minimum or maximum, as required.
Hold the pressure control and tighten the lock, using
LIGHT pressure.
The pressure control has a small mark to indicate it's
position.
NOTE ..... It is not necessary to overtighten the lock as this can
damage the mechanism.
WARNING
ALWAYS OPERATE THE MACHINE AT THE LOWEST
PLATEN PRESSURE NECESSARY TO MAKE A
SATISFACTORY PRINT. DAMAGE TO THE MACHINE WILL
OCCUR IF EXCESSIVE PRINTING PRESSURES ARE
USED.

3.1 .......Feed Bed
The Feed Bed is set as follows:-
-Raise the feed cover.
-Raise the primary sheet feeder.
-Loosen both side guide locks and open up the side guides, to
allow one sheet of your job to be placed on the Feed Bed.
-Paper is normally fed centrally on the machine, and setting the
near side-guide to the scales, will facilitate this. Set the inside
edge of the side guide to the scale. (See note 3 for feeding multi-
part sets with glued edge to the side).

Section 3
SETTING
-For odd or unknown sizes, fold the workpiece in half, along it's
length, place on the centre line, and move the near side-guide up
to the edge of the paper.
-Having set the near side-guide, set the far side-guide to the paper.
Accurate positioning of these guides is essential for reliable and
straight feeding.
-If set too tight, poor feeding will result. If set too loose,
inconsistent perforating and scoring will result, and to a lesser
extent, inconsistent numbering too.
-With both guides set, use a single piece of your work and pass it
below the friction feed tyre.
-If the work will not fit below the friction feed tyre, loosen the nip
wheel by turning the adjustment screw.
-Now tighten the nip adjustment until a very slight drag is felt on
the paper or set. The feed bed is now ready for loading with
paper.
-The paper must be spread out (shingled), so that the top sheet
approaches the friction tyre first.
-Now place the primary feeder on to the work and lower the feed
cover.
Note 1..... The scales are for guidance only, and the side guides
may have to be adjusted to obtain a straight perforation.
Note 2..... If double or multiple sheet feeding occurs, tighten the nip
adjustment.
Note 3..... For sets to be fed open edge leading, place the glued
edge nearer to the feed wheel, instead of central. Offset
by approximately 1/3 the width of the sheet.

3.2 .......Numbering
Fit a Numbering Head to a collar, using the scale on the collar to
obtain the correct position. The scale relates to the distance from
the top of the sheet, to the top of the number. Line up the back
edge of the Numbering Head with the scale. (To make the scale
position accessible, operate the Auto/Man switch and turn the
machine using the handwheel at the rear of the machine See Fig
2.11)
Position the Numbering Head sideways, by releasing the collar
locking screw. This locking screw is only accessible by operating
the auto/man switch, (see 2.1) and rotating the machine by hand.
NOTE .....Every time the collars are moved, the advance cam will
need moving and the hold-down wheels checked , by
rotating the machine by hand. NEVER operate the
machine under power until the auto/man switch has been
released, and the Numbering Head has been turned one
complete revolution by hand, to ensure that the hold-
down wheels and advance cams are positioned correctly.
3.3 .......Setting Numbering Digits
Set the Numbering Head digit wheels using the pointed stylus,
supplied with your Numbering Head. The wheels can only be
turned in the direction shown in Fig. 3.21
To avoid having to reset the digit wheels after make-ready, set
them to a number somewhat lower than, (forward heads) or higher
than, (backward heads) your jobs required starting number.
Standard heads have seven digits. If less than seven digits are to
be printed, up to six zero's may be depressed so that they do not
print. ( This feature may not apply to all Numbering Heads )
To depress the digits, turn the digit wheel until the zero is at the top
of the head. Turn the wheel further while pressing the zero down
into the head. The zero will drop down and remain down.
To release the zero, turn the wheel further in the normal direction.
