IV. USE OF THE MACHINE
The PR245S press was designed to apply all quality transfers in medium and great series.
This equipment was tested in our workshops to obtain a one-year guarantee against any manufacturing vice.
The adjustments (pneumatic, electric and mechanic) carried out by our technicians in the workshop as well
as the securities implemented on the machine should not be modified in any case. Otherwise, the S.E.F.A ®
Company will deny all responsibilty on possible problems linked to the machine.
Before starting any pressing operation, it is recommended to carefully read the safety instructions as well
as the directions for use.
1. SAFETY
THIS EQUIPMENT IS DESIGNED FOR SINGLE USE ONLY
USE BY QUALIFIED STAFF ONLY
Symboles internationaux :
You will find most of these symbols on the SEFA machines.
Some important points for the safety of the staff:
Avoid touching the hot parts of the equipment while in use.
Do not put your hands between the plates once the equipment is activated.
During handling action, ensure that the operator do not risk anything in terms of burn,
electrocution or other.
Carry out a daily inspection of the machine before starting the production.
In the zone close to the machine, make sure that nobody is around before you start.
If the machine does not work properly, immediately cut the energy supply and look for the
cause making use of the book’s chapter ”Service”.

Safety devices on the machine:
Protections and safety devices should not be modified. They must be put together again in
case of possible removal for maintenance.
They must be kept in place and in good condition during normal operation.
The PR 245 S is equipped with security systems protecting the operator from any risk of pinching.
The main elements of security are:
The emergency stop
Situated on the left on the front of the machine: if the operator actions it, he switches the machine off.
The bimanual control
To control the pressing, only a constant and simultaneous hold of both push buttons enables the heating
plate to go down. It is necessary that the heating plate is in full lock on the right side or the left side, so that one of
the 2 “thrust” microswitches is activated. It is only at this moment that the operator can action both push buttons. If
the operator does not constantly maintain the pressure on the two buttons until the two plates are in contact, the
heating plate goes back up automatically.
OPTION : Control by pedal
It will be possible for the operator to pilot the plate lowering using the pedal. In that case, the protection of
the operator will be ensured by the security cover.
Checking of the functioning of the safety device:
¾Periodically try the emergency stop
¾Daily control the functioning of the bimanual
¾Control the good functioning of the security cover (in the case of the option).
After an emergency stop:
Check if no other problem remains on the machine.
Unlock the emergency stop turning the red part: the machine will reset itself automatically.
Manuals
Technical documentation on the components used is provided to you on delivery of the machine. Please
read it before any handling of the S.E.F.A ®machine.

2. INSTALLATION
USE BY QUALIFIED STAFF ONLY
Do not manipulate the machine by the plates!
Unpack the machine.
Place it on a stable table handling it by its frame.
After having properly positioned the machine on it working place :
•Electrically plug the press in with the provided plug (220 Volt + Earth / 50 or 60 Hertz),
•Pneumatically connect the press to your compressed air network (3 bar mini, 10 bar maxi).
3. DESCRIPTION OF THE RUNNING CYCLE
1. The operator will have to power up the machine using the main switch which is on the back of the
machine,
2. Check if the screen lights on. After a welcome message, it will indicate the values preset in the
workshop,
3. Set the temperature thanks to the keyboard (to define according to the type of transfer),
See SETTING § 1,
4. Set the application time thanks to the keyboard (to define according to the type of transfer),
See SETTING § 1,
5. Adjust the pressure thanks to the regulator (to define according to the type of transfer) ,
See SETTING § 2,
6. Place the item on the inferior plate,
7. Adjust the transfer sheet,
8. Swivel the head of the press using both handles on the sides of the jack support,
9. When the bracket is in full lock, press simultaneously on both push buttons (or on the pedal). Maintain
both buttons until the heating plate is in contact with the inferior plate,
10. At the end of the timer countdown, the heating plate will go back up,
11. Move the heating plate away and remove the item,
12. Start the operation again from n° 6 (if the settings do not change otherwise start again from n°3).

manometer’s dial at the front. Pull the head of the regulator upwards, then turn:
ªclockwise to increase the pressure,
ªanticlockwise to decrease the pressure.
3. ADJUSTMENT OF THE BRACKET HEIGHT
According to the type of the item to mark or to adapt to the accessories of the PR 245 S (ex. cap
accessory), the height of the bracket has to be modified. Turn the wheel situated on the column:
ªclockwise to lower the bracket,
ªanticlockwise to raise the bracket.
¾Press on ”Temps”,
¾Press on ”-” to decrease the indicated value
Or on ”+” to increase it,

2. REPLACEMENT OF USED PARTS
-The mat in silicone mousse
a) Check that the plate is cold.
b) Make sure that the plate surface is properly clean. Possible use a soft solvent such as White Spirit.
c) Use a RTV-1 tube of glue to stick the mousse to the aluminium plate (NB : read the instructions on the
tube packaging).
d) The mat and the plate must be clean and dry before starting any gluing.
e) Spread a fine layer of glue in a homogeneous way on the plate and immediately apply the mat making
sure that there is no air lock (NB : an indented spatula similar to the one used to lay tiles would suit
perfectly).
f) leave to settle overnight at room temperature with slight pressure and without heat.
-Other parts
Get in touch with your retailer to evaluate their change or their repair.
3. MAINTENANCE
The S.E.F.A ®heat presses hardly require any maintenance. To ensure a good functioning, follow the
preventive notice indicated below:
-Do not heat up objects which could deteriorate or even cut the silicone rubber or damage the teflon
surface of the heating plate
-Every so often and when the plate is cold, clean the machine with a clean cloth and white spirit (NB: as
this product is flammable, use with care and keep it away from any heat source)
-When the heating plate is hot and unused, keep it in open position.
DAILY : Clean the mousse and the heating plate surface (when cold) with a dry cloth or
impregnated with spot remover.
Check the air filter behind the bracket, drain it if there is too much condensation.
MONTHLY : Check the column and grease it.
ACCORDING TO THE USE : Change the mousse every six months.
