Oil supply for Horizontal Type (Refer to Fig.13)
1 Remove the oil filler plug.
2 Fill oil through oil filler port while checking oil
level by the oil gauge.
3 Fill oil in place on the oil gauge.
4 Replace the oil filler plug.
Oil supply for Vertical Type (Refer to Fig.14)

(5) Oil Discharge
Remove the drain plug shown in Fig.13, 14 to discharge oil
(6) Long-term Stoppage
Stoppage Period
Approx. 1 month
More than 1 month
Change the oil and operate the unit for several minutes before stopping the unit.
Flush the unit, fill with rust-preventive oil, and operate the unit without a load for several
minutes before stopping the unit.
· Before starting operation after long-term stoppage, always change the oil. This will ensure that the lubricant is
free from deterioration that may have been caused by long-term stoppage.

(4) Oil Supply
• Be sure to fill with oil when the unit is not operating.
• When the viscosity of oil is high, it may take some time for the oil to settle. Be careful not to over-fill.
(If oil is filled above the upper line, the temperature will rise due to the churning heat of the oil.)
• Use the lower red line on the oil gauge, as a guideline for the normal oil level during operation. (Immediately
following commencement of operation, the oil level may fall below the lower red line, but should not be of particular
concern, since the oil level will recover, as the oil viscosity falls due to the drive operation.)
