Matters to be paid attention to when using motor
8-1 Please
lay the motors carefully in transportation to avoid any damage to the motor
body or its electric function because of collision.
8-2 Please
do not leave the motors in the environment of high temperature, high
humidity and gas that will cause rust and corrosion. Please don’t store the
motors for over 6 months.
8-3 Please
do not lock the motor shaft when the electric power is supplied.
8-4 Please
do not touch the weights when motor is rotating.
