Important Notice
■Purpose and Application of Use
・ The ARG suppresses a rolling motion of the ship.
・ The ARG applies a principle that the Gyro torque (force) is
generated by inclination of the flywheel rotation at high speed.
■General Information
・In order to safely install and operate the ARG

(a) Only the repairmen, who have received the specified training
about the ARG, are permitted to perform the test run and
inspection other than items mentioned in this manual.
(b) Before installation of the ARG, carefully read this manual of
the ARG for comprehending the details. If starting the work
with insufficient knowledge, it may cause the ARG failure or
an accident resulting in injury or death.
(c) Do not disassemble and modify the ARG by yourself.
If the ARG is disassembled or modified by the user,
−It may cause a decrease in the ARG performance.
−It may endanger human life.
−It may cause a health problem.
−It may cause damage to the ARG or ship.
・Depending on the type of the ship, it may be necessary for you to
use multiple ARGs. In this case, the methods of installation and
electric wires are somewhat different from those described in this
manual.
・Please observe the applicable governmental and local laws and
regulations.
・Please observe the governmental and local regulations for exportation
of the ARG.
・Please observe the governmental and local regulations for disposal
of the ARG.
