  • Page 44 8. Daily Inspection and Maintenance Common (3) Amount of oil Table 8-5 shows approximate quantity of necessary oil. There are differences in the actual oil feed quantity among machines because of the difference in structure and so on. Even if the feed quantity of lubricating oil is the same as that indicated in Table 8-5, the actual quantity of oil in the product may be excessive or insufficient.
  • Page 45 8. Daily Inspection and Maintenance Common - Ensure that the gearmotor or reducer is stopped before feeding oil to it. - If the viscosity of the oil is high, it may take time for the oil level to become uniform. Take care not to add an excessive quantity of oil. - Add oil until it reaches the center of the oil gauge.
