General Instructions
This Service Instructions manual
isprovidedasasupplementtothe
OperatingInstructionsmanualfor
the repair and maintenance
personnel and, therefore, is
referredto the OperatingInstruc-
tions manual in several cases.
As a great deal of setting and
repairinstructionsaffectthesafety
oftheoperatorandofthemachine,
such work should be performed
bytrainedorinstructedpersonnel.
In this place, a few fundamental
instructions be given which, as
practice shows, are often disre-
garded:
• Whenever you remove sepa-
ratingguardingssuchashoods,
panelings etc. for repair and
maintenance purposes, always
remember that, in most cases,
machine elements with hazard-
ousmovementsarebehind. For
this reason, guardings must, by
all means, be refitted after com-
pletion of work.
• Open switch cabinets and
switching rooms do not only col-
lectdustthatleadstofailures,but
also involve danger to life and
limb.
You are encouraged to take
theopportunityPERFECTAof-
fers you to have your techni-
cians trained at our Training
Centre.
Safety Inspection
Duetotheirwayofoperationcon-
sisting of hazardous movements
such as clamping and cutting,
guillotinesmustmeetanumberof
safety regulations. Such regula-
tionsaremetby"SafetyDevices"
described under the same cap-
tion in the Operating Instructions
manual.
According to the Accident Pre-
ventionProceduresforthePrint-
ing and Paper Processing In-
dustry, VBG 7i, § 40, the user
must ensure that the safety
devices-particularlythecontrol
system-shouldbeinspectedby
aspecialisteveryfiveyears.The
result of the inspection should
be recorded and filed.

Knife Drive
The timing of the S52, S53, S54
control switches on the crank-
shaft is explained by a chart in
the "Knife Control" section (con-
trol switches).
Theproperfunctioningofthecon-
trolswitchescanbecheckedfrom
the service menu (I/O Test).
S53
- Knife-down travel.
-Clamp locking whilethe knife is
coming down.
S54
- Checking the UDC.
- Emergency shut-off in case of
S52 failure.
The gap shown in the timing
chart (switching distance) be-
tween S54 and S53 should be
1/3to1/2ofaflywheelturn.For
thispurpose,energizetheclutch
(referto"ManualCranking"inthe
Operating Instructions manual)
andchecktheswitchingdistance.
Whentheknifedriveisautomati-
callystopped,theknifeedgemust
protrude at least 6 mm over the

The cam of S52 should be set
sothatthemachinewouldstop
at the upper dead centre and
thecamfollowerofS54comes
to stop within the first third of
its cam length.
When the knife beam runs over
the UDC (S54 no longer oper-
atedatstopposition),anysubse-
quent cut triggering is disabled.
The display reads Error 28:
Safety Module Detecting Error.
Bypressingthe"C"key,concrete
Error 7 appears: Knife Overrun.
After turning off and on the ma-
chine,thesubsequentcutcanbe
restarted by the knife pushbut-
tons.
If there is another overrun at the
UDC,slightpre-stoppingcorrec-
tioncan beperformed byturning
forward the entire cam package
within the permissible range.
If such correction by the above-
mentioned cam shifting is not
successful, i. e. if there is still
overrun, checking the clutch/
brakeassemblyoftheknifedrive
should,underanycircumstances,
be checked.

Checking and Setting the Air
Gap
Under normal operating condi-
tions, the air gap should be
checked once per year.
For air gap A, refer to the Table
(Fig. 5).
• Engaged state (clutch "ON"):
If air gap A min is smaller than
specified in the Table, Fig. 5,
shims 10 of uniform thickness
should be inserted
between coil body 7 and friction
ring 8 (Fig. 4) for
machine sizes 76 and 92, or
between friction ring 8 and
spacing segment 9 (Fig. 3) for
machine sizes 115 and 132.
Forthispurpose,slackenscrews
11aroundthecircumferenceand
then re-tighten them uniformly.
The shims are available in vari-
ous thicknesses. Refer to the
Spare Parts Catalogue in the
Operating Instructions manual.
After the successful installation
of the shims, make sure that air
gapAmaxspecifiedintheTable

Cutting System
All PERFECTA guillotines work
on the basis of what is called the
slantrockingcut,i.e.theknifeas
the cutting tool moves along a
curved path from left to right.
All findings and experience
related to the cutting system
regardingthequestionsofcutting
stock, knives, clamping, cutting
inaccu-racies and their
rectification are summarized in
our"CuttingCompendium"that
youcanob-tainfromPERFECTA.
Play in the Knife
Beam Guideways
Inadditiontomanyotherfactors,
a smooth guidance of the knife
beam is a prerequisite to a high-
quality and high-accuracy cut.
Over the years, and depending
uponthe workingconditions, the
guideways are subject to wear,
although the latter is minimal.
Therefore, the play in the knife
beam guideways should, from
time to time, also be measured
andreadjusted,ifrequired.
Machine Sizes 76/92 (Fig. 16)
Knife beam 1 moves between
slide surfaces 2 on the machine
frameandguidestrips3.Theguide
strips have been adjusted with
respect to the knife beam with
shims4sothatgapsrequiredfor
establishing the necessary
lubrication film is
< 0.05 mm.
Checking the play:
• Push the knife beam (without
knife)against the framefrom the
rear at the top and bottom posi-
tions. Check the play between
the knife beam and the guide
strip on the left and right sides
using a feeler gauge.
• Removing shims reduces air
gaps. Underany circumstances
shoulditbeensuredthatthegap
is not too small, as, otherwise,
lubricationisnotguaranteed,with
the knife beam tending to get
jammed.
Thiswouldresultinseizureofthe
sliding surfaces.
Whenever the positions of the
guide strips are changed, the air
gap between the knife back and
the clamp edge must always be
checked as described under
"Clamping System" and read-
justed, if necessary.

the knife beam and the guide
strip on the left and right sides
using a feeler gauge.
If required, readjust gapsas fol-
lows:
• Set the knife beam to medium
feed height and push it against
the frame.
• Remove the front paneling.
• Slacken clamping screws 8 on
the left and right of the cutting
table (8 screws in total).
• Remove plastic cover 7 and
adjust guide strip 3 against the

Cutting Table
All PERFECTA guillotines are
suppliedwithstandardcuttingta-
bles and the associated side ta-
bleswith groundsurfaces andof
special-quality cast iron. In the
factory, the tables are provided
withtemporarycorrosionprotec-

the machine is installed at the
user's, this corrosion preventive
mustberemovedwithwhitespirit.
Never use any caustic agents.
The clean table is susceptible to
corrosion,particularlyinthehan-
dlingarea.
PERFECTAofferscorrosion-pro-
tective wax which inhibits corro-

be repeated from time to time.
If small deposits of rust should
have built up as a result of insuf-

them immediately. Never use
abrasive cloth or sand paper. Ti-

"Adjusting Square Cutting"in the
OperatingInstructionsmanual.
Around the horizontal axis, the
carriage is supported by three
fixedrollers5and one eccentric-
ally adjustable roller above the
guideway beam and by four ec-
centrically adjustable rollers 6
beneath.
Around the vertical axis, the
carriage is secured against dis-
tortionbytwofixedrollers5onthe

adjustable rollers6 on the left.
Ifsome play should occur aftera
longer period of operation, you
can use the eccentric rollers to
eliminate it.
For this purpose, slacken outer
nut7and gently rotate eccentric
pin 8 until the roller gets into
contact with the guideway. Re-
tighten the nut.
