Safety switches
Safety switch on the safety cover
Before starting regular automatic production on the machine, close all safety covers.
Since a screen displays the message prompting you to supply a material when necessary, open the
corresponding cover according to the target material and then conduct the work.
If you accidentally open a safety cover during automatic production, the machine comes to an
emergency stop to ensure the safety of operators.

Servo switch
Since an operator needs to put the hands or part of body into the machine for changeover or
maintenance, the operating panel is equipped with the servo switch in order to ensure on-the-job
safety. When the servo switch is turned OFF (O), all of the drive shafts of the machine will be inactive.

Usage of warning sheets in maintenance
Before performing maintenance, affix the included warning sheets (see below) to prominent positions,
such as the operating panel or the vicinity of it, for safety.
During the maintenance by two or more persons in particular, as well as using these warning sheets to
ensure safety, be sure to send signals.
This warning sheet uses a magnet. Do not use it or store it near magnetic media or any other items
susceptible to magnetic influence.

The motor that does not stop if an emergency stop button is pressed
Even if an emergency stop button is pressed, the motor for the vacuum pump does not stop. This is
because the motor prevents picked-up components from dropping. Since it is installed inside the frame,
there is no danger that workers may receive an electric shock or become entangled with it.
