and contact us.
■ Daily inspection
・ Check to ensure that the load condition is appropriate.
・ Check to ensure that the speed drive housing temperature is not extremely high during operation
(A temperature of up to approximately 50ºC higher than the ambient temperature will not cause any problems).

・ Check to ensure that the lubricating oil is not dirty, and that the degree of transparency is high.
・ Check to ensure that there is no oil leakage
(for example, check oil seals on the input and output shaft parts, O-rings, oil gauge, and the area around the oil filling and drain ports).
■ Periodical inspection
(every three months)
