maintenance from the technical service.
The request of maintenance can be of two
types:
-
Ordinary maintenance
-
Extraordinary maintenance.
Here are the lists of maintenance operations
to be carried out in either case.
Ordinary maintenance- every 1000 hours
-
Verify that all machine safety devices,
either active or passive, are in good
working order
-
Grease the drive chain
-
Check oil levels
-
Clean the steam extraction pipes and
extraction fan using a powerful vacuum
cleaner
-
Check that the felt that covers the roller
is in good working order and measures
the circumference required, as indicated
above
-
Verify that the steam circuit is tight (for
steam-powered models)
-
Spread anti-static wax over the press
-
Adjust the linen-discharge device and
ensure that the springs are not damaged
Extraordinary maintenance - every 2000
hours
When
carrying
out
maintenance, go through all ordinary
maintenance operations and add the
following:
-
Adjust drive chain tensioning
-
Check the press-driving cylinders for
oil leaks
-
Tauten feeding bands
-
Verify that the terminals on the heating
contactors are tight
-
Check that power input on the three
phase leads is even when heating;
otherwise, check that the heating
elements are in good working condition.
Every 4000 hours of operation (once every
two servicings), change the diathermic oil
with oil possessing properties equivalent to
the factory-supplied oil.
Factory-supplied oil: BESTERM-3
IMPORTANT: do not disperse worn-out oil
in the environment: comply with the
provisions for the disposal of worn-out oil.
INSTRUCTIONS
FOR
REPLACEMENT OF THE COVER
The roller cover is composed of two different
layers:
1) Metal elastic cover made of a strip type
spring wrapped around the roller: under
normal conditions, this requires no
maintenance.
2) Nomex felt layer, 6 mm thick.
To replace the cover entirelly, proceed as
follows:
IMPORTANT: ALWAYS KEEP THE
PRESS IN IDLE POSITION! IF THIS RULE
IS NOT OBSERVED THE MACHINE
COULD
BE
PERMANENTLY
DAMAGED!
-
Remove the linen feeding tray, the
machine top guard and the linen take-
off device;
-
Ensure that the press basin is in its
recessed position and idle, away from
the roller surface:
If the press basin touches the roller in
any point, detach it completely by
moving the press basin supports.
-
Remove the power circuit fuses (F1-F2-
F3-F4-F5-F6)
-
Loosen the flannel side ties, open the
sides closing against the roller ends.
-
Lift the end hem of the flannel until the
starting hem appears, which is in direct
contact with the springs.
-
Have the roller turn very slowly and
gradually remove the flannel from the
starting hem until the cover is completely
unwrapped.
-
Clean any dirt trapped in the wrapped
up spring using a powerful vacuum
cleaner.
-
Bring the new flannel near the roller.
Lay it on the feeding unit so that the
band that is sewn to the sides and
contains the fastening strings faces
downwards; the felt must be perfectly
centred on the roller, the starting hem
must be fastened under the spring
covering plates. Make sure that the
extraordinary
flannel hem is aligned to the roller axis.
The nomex side of the felt must face the
press basin.
-
Proceed slowly helping the flannel into
the feeder. Ensure that the new cover
wraps gradually and smoothly by
keeping the felt taut.
-
Tie the flannel ends and insert the extra
string under the flannel itself.
-
Disconnect the machine from the power
mains using the master disconnection
switch on the wall and the built-in
disconnection switch. Install the
machine's upper guard, the linen
feeding tray and any previously removed
parts.
-
Ensure that the felt covers the roller
completely and next restore the fuses.
-
Switch the machine on and warm it up
to 180°.
-
Have the roller turn slowly and
pressurise the press basing to setting 4.
THE
-
Allow around 15 minutes of operation
for the flannel to set.
-
Switch the machine off and ensure that
the start and end hems of the flannel
overlap properly.
-
Cut and remove any excess or extra
thread using a sharp blade.
While wrapping up and unwrapping the
Nomex felt, alarm 7 will appear, which
indicates low pressure in the hydraulic circuit
because the hydraulic unit is dead; this is
normal. To avoid this alarm it is necessary
to wrap up the flannel by steps, starting and
stopping roller movement for no longer
than 15 seconds. If the alarm trips, switch
the machine off and then on again.
A slight remainder gap is absolutely normal
and will be closed gradually with use.
Should the metal cover be damaged as a
result of local or widespread crushing, it
will be necessary to repair the spring that
supports the cover. In this case, have the
defect remedied or the cover replaced
altogether by the technical service.
8.4 IDENTIFYING AND ORDERING
SPARE PARTS
In order to identify the code numbers of
spare parts, please refer to the exploded
views of the appliance and the related spare-
part list. Once you have identified your
codes, send a standard written order to the
manufacturer, mentioning clearly machine
model, serial number, feed voltage and
frequency and, of course, including the code
and description of the spare part needed.

PARTS.
9. HOW TO DECOMMISSION,
DISMANTLE AND DISPOSE OF THE
APPLIANCE
If the appliance is no longer to be used, it is
advisable to decommission it and suitably
dispose of the resulting materials,
considering the information provided in
chapter 3. For the sake of the environment,
sort the materials in accordance with the
waste disposal provisions in force in your
country, so that they can be properly disposed
of or recycled.
All the structural parts composing the
machine can be treated as solid urban waste,
except for the metal parts, which nevertheless
are not classed among special waste in most
European countries.
The oil disposal and the hydraulic circuit
that drives the press basin must be disposed
of by the centres specialising in recovering
used oil.
The battery powering the memory, which is
installed on the control electronic board,
must be disposed of as special refuse, in
compliance with the local legislation.
The oil that the machine is factory-charged
with has the following features:
Hydraulic oil:
NUTO H32
Diathermic oil: BESTERM-3
34
INDISPENSABLE
FOR
Oil for hydraulic circuit
