8. 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. |
