Please remove drain plug located under the unit for oil draining when lubricating oil is still warm.
Removing the air breather makes draining and supplying oil easier.
Supply oil through the filling port on top of the main unit. Check the oil level with a dipstick or visible oil gauge
(Fig.5).
Screw the dipstick to its deepest position to check the oil level; otherwise, the measured oil level will be incorrect
(Fig.6).
Care should be maintained during the oil-filling process to ensure that loose nuts, bolts, washers, dust, water and other
such foreign material do not enter the unit.
If the oil level is lower than the range, the unit will not be lubricated.
If the oil level is higher than the range, deterioration of the oil is accelerated due to oil temperature rising.
The oil level should be
within this range
