General information

Improper check of the oil level may result in damage to the gear unit.

Possible damage to property.

• Check the oil level only when the gear unit has cooled down in idle state. SEW‑EURODRIVE recommends checking the oil level at an oil temperature of 20 °C to 40 °C. The oil level must be in the middle between the markings [1] and [2] at the oil dipstick or oil level glass.
• For gear units in fixed and variable pivoted mounting position, observe the notes on the following pages.
• When the gear unit is equipped with an oil dipstick and an oil sight glass, the oil level on the oil dipstick is decisive. The oil level on the oil sight glass is only an approximate value.
• Elements for checking the oil level, oil drain, and oil fill openings are indicated on the gear unit by symbols.
• Check the oil level again after the first few operating hours when the gear unit is at standstill.
