Gear Lubrication
• Grease Lubricating Type (4095 to 4115)
The gearbox is filled at the factory.
• Oil Lubricating Type (4130 to 4190)
All oil is drained from the gears prior to shipment. The gearbox must be filled to the red
line at the top of the oil gauge before initial use.
We recommend using industrial extreme-pressure gear oil or SP type or JIS K 2219 in-
dustrial gear oil type 2 or equivalent. See the following table.
