7. Operation Procedure
7-1) Power ON
Connect the power plug to the socket correctly.
The power is supplied to the temperature controller. The controller indicates the present
temperature (upper display) and preset temperature (lower display).
 Be sure to connect an earth line.
7-2) Temperature setting (Temperature controller)
1) Check that the pilot lamp is off (no heating or cooling).
2) Push the para display change button three times to indicate “SP-1” on the present
temperature display. At this time, the preset temperature display indicates the preset
temperature.
* The preset temperature before shipping is 190C.
3) Push the (up) button to raise the preset temperature or push the (down) button to
lower. Push the button once and the flickering figure increase or decrease 1C each
time.
Pushing the (side) button shifts the figure of temperature.
4) The figure of the preset temperature display is flickering when the figure of the
temperature is adjusting.
The preset temperature will be fixed when no pushing is made for 2 sec or more.
5) Push the para display change button two times to return the present temperature
display to the original state.
7-3) Hold time setting (Temperature controller)
1) Check that the pilot lamp is off (no heating or cooling).
2) Push the para display change button four times to indicate “E1.on” on the present
temperature display. At this time, the preset temperature display indicates the hold time
(in sec).
* The hold time before shipping is 60 sec.
3) Push the (up) button to increase the time or push the (down) button to decrease.
Push the button once and the flickering figure increase or decrease 1 sec each time.
Pushing the (side) button shift the figure of hold time setting.
4) The figure of the hold time display is flickering when the figure of the hold time is
adjusting.
The hold time setting will be fixed when no pushing is made for 2 sec or more.
5) Push the para display change button once to return the present temperature display to
the original state.
The indicator of temperature returns to the preset temperature.
 Although changing the preset temperature and hold time is possible also
during heating or cooling, heating or cooling may become incorrect.
Hence avoid changing the setting during heating or cooling since it may
cause incorrect endless splicing.
WARNING
CAUTION

7-4) Operation
1) To start operation, push the start switch for 0.5 sec or more.
2) On starting of operation, the pilot lamp lights and the heating of upper and lower heat
plates start.
3) The machine operates in the sequence of; heating to the preset temperature,
temperature holding (period previously set) and cooling. On completion of temperature
holding, the pilot lamp goes off, and the machine operate the cooling fan until present
temperature goes below 45C.
4) When present temperature goes below 45C, the cooling fan stops and the machine
become a standby.
 Be sure to wear heat-resistant gloves when operating the press.
Failure to do this may cause burn.
 An operator should not leave the machine in use. Take a measure to
prevent other people from touching this machine unexpectedly.
Failure to do this may cause burn on other people.
7-5) Discontinue on the way
Disconnect the plug if it becomes necessary to discontinue the machine in operation.
* Even if the plug is disconnected in operation, preset data of preset temperature and
hold time are maintained.
 The machine when discontinued on the way is kept at high temperature.
Be sure to wear heat-resistant gloves when handling the machine.
Failure to do this may cause burn.
 The operator should take a measure to prevent other people from
touching this machine unexpectedly, until the machine temperature
lowers near to room temperature (about two hours).
Failure to do this may cause burn on other people.
 When the machine is discontinued on the way in making belt endless
splicing, do not use the belt.
Endless splicing may become imperfect possibly spoiling the full functioning
and performance of the belt.

when carrying out the
following works.
1) Place the pre-setter prepared as described
in section 8-2) Belt setting on page 12,
between pre-setter guides as shown in Fig.

* Place the pre-setter at the center as
much as possible.
* When placing, be careful not to pull out
the belt from the pre-setter.
2) Gradually close the top cover so that the
upper plate is positioned in parallel with the
pre-setter.
* Quick closing the top cover may cause
the pre-setter to shift its position or the
belt to come off the pre-setter.
3) Set the hook and turn the rotary handle until
it slips as shown in Fig. j.
* Excessive turning will cause the handle
to slip in removing also, disturbing easy
removing.
4) Push the start switch to start endless
splicing.
* It takes about 60 min to finish one cycle
of operation (heating, temperature
holding and cooling) with the presetting
before shipping at 23C of environmental
temperature.
* The required time changes according to
ambient environmental temperature or
the setting of preset temperature or hold
time of the press.
5) On completion of temperature holding, the
pilot lamp goes off and operate the cooling
fan. Check that the cooling fan has
stopped after cooling completion before
opening the top cover.
6) Take out the pre-setter and remove the
upper one, silicone sheet and belt in order.
* Use the belt after it has cooled down to
room temperature.
