WARNING
The SL-R12EX has not received the model certification examination in accordance
with Article 44-2 of the Japanese Industrial Safety and Health Law. As a result, the
SL-R12EX cannot be used in Japan as a “Safety Device for Presses and Shearing
machines” as established in Article 42 of that law.
When using the SL-C Series, including SL-R11 and SL-R12EX with mechanical
press equipment in the United States, check the regulations stipulated in
OSHA1910.217 and ANSI B11.1, B11.2, and B11.3, and be sure to follow those
regulations in both the installation and use.
