8. Matters to be paid attention
to when using motor
8-1 Lay the motors carefully in transportation to
avoid any damage to the motor body or its electric
function because of collision.
8-2 Storage temperature: 20±10°C. Do not leave
the motors in the environment of high temperature,
high humidity and gas that will cause rust and
corrosion. Do not 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. |
