(4) Oil Quantity
An estimated oil quantity for standard specifications is shown in “10. Oil quantity". Use a dipstick or visible oil
gauge to check the oil level even after filling with indicated oil quantity.
(5) Fill/Drain oil
Supply oil through the filling port on top of the main unit. Check the oil level with a dipstick or visible oil gauge.
(Fig. 7-1).
Screw the dipstick to its deepest position to check the oil level; otherwise, the measured oil level will be incorrect.
(Fig. 7-2).
Prevent bolt, washer, dust, water or other foreign object from entering during oil-filling process.
If the oil level is lower than the range, the unit will not be lubricated sufficiently.
If the oil level is higher than the range, deterioration of the oil is accelerated due to oil temperature rise.
Remove drain plug located lower part of the unit to drain when lubricant is still warm.
