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 to a grounded outlet.
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 185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 300 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) Discontinuing operation of the machine while in use
Disconnect the plug if it becomes necessary to discontinue operation of the machine while it is
in use.
* Even if the plug is disconnected during operation, preset data of preset temperature
and hold time are maintained.
When operation is discontinued during use, the machine is kept at high
temperature. Be sure to wear heat-resistant gloves when handling the
machine.
Failure to do this may cause burns.
The operator should take measures to prevent other people from touching
the machine accidentally, until the machine temperature lowers to near
room temperature (about two hours).
Failure to do this may cause burns to others.
If machine operation is discontinued during the process of splicing a belt,
do not use the belt.
The splice may become defective, reducing the function and performance of the
belt, or rendering it unusable.

* 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 torque limiter until it
slips as shown in Fig. j.
* Excessive turning will cause the torque
limiter 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.
