b) For compressed air machines, close the
ball tap assembled on the air compression
line "POS. 25" (see page 10-5).
c) Turn off the electrical control board switch
and then the main switch fitted to the
electricity supply.

MAINTENANCE

The following instructions are of prime importance
in keeping the machine
ensuring its maximum performance, and avoiding
expensive down time.
The first part of this section is divided into
chapters according to periodic maintenance
schedules.
N.B.: The frequency indicated (weekly, monthly,
etc.) is indicative and refers to a machine that
operates under 'normal' conditions.
The individual customer has to decide on the
exact frequency of the maintenance work on the
basis of the following guidelines:
• The amount of work done by the machine;
• The amount of dust in the air;
• Other local working conditions.
All the maintenance
undertaken with the
switched off, and in particular:
a) The general electrical power switch must be
off and the plug removed from the socket.
b) The two gate valves "POS. 67" fitted to the
steam line and the condensation return "POS.
68" (see page 10-4) must be closed.
c) For machines with compressed air, the
compressed air ball valve "POS. 25" must be
closed and discharged any condensation
deposited in the compressed air filter bowl by
turning the tap "POS: 1" (see page 10-5).
d) The hot parts of the machine must be left to
cool (internal pipes, valves, the boiler, if fitted,
etc.) in order to avoid burns.
Only by observing all these precautions, and
the particular conditions relating to the individual
maintenance jobs, is it possible to carry out
maintenance work on the machine with complete
safety. Remember 'you can never be too
careful'!
In order to make potential dangers more evident,

parts of the machine: the meaning of these

N.B. In any case, the maintenance work must
be undertaken only by competent personnel
who can take personal responsibility for their
own safety and that of other persons, animals
and property. The law, and in particular the
latest EU Directives, severely punish the
owner of a machine who allows maintenance
work to be carried out by non-qualified
personnel

WEEKLY MAINTENANCE

For machines with compressed air: check the
compressed air filter, discharge the water, and
clean the filter cup.
SIX MONTHLY / YEARLY
MAINTENANCE
a) Check the various gaskets and gate valves
as continuous heating and cooling can cause
leaks. Should there be leaks, remove the
gaskets and gate valves and replace with
new to prevent further leaks.
Clean the filter fitted on the condensation
b)
return pipe that, if dirty, stops drainage and
allows the siphoning back of water.
Only for machines in saving version,
c)
clean the check valve placed under the
condensate separator.
d) Clean the air pipe from any impediment
(dirty) that stops the air flow during the
ventilation phase.
e) Check the condition of all the labels and
plates on the
instructions). If they are in poor condition,
replace them.
f) If the surface of the rubber pads assembled
on the clamps becomes uneven, replace them
in order to avoid garment marking.
g) The efficiency of the former depends upon the
steam and air passing through the nylon bag;
so if the bag is dirty the efficiency of the
former is reduced. It is advisable therefore to
disassemble the bag from the former and
wash it or replace it.
