Perform periodical inspection to check that the aforementioned storage procedures have been taken properly, and that the storing methods
are correct.
(1) Return the product to normal conditions from those taken for storage (such as for the amount of special oil).
(2) Since bearings may partially run out of grease resulting from the grease hardening during long-term storage, be sure to turn the motor
shaft by hand from the fan side before operation, and check that there are no problems.
(3) Since exposed parts of rubber and/or resin parts in the oil seal, O-ring, and oil gauge, etc., may become deteriorated due to environmental
influences, such as temperature, humidity, and/or ultraviolet rays, check those parts before resuming operation. If any deterioration is
found, replace with new ones.
