Oil level check: Visually using a sight glass
The oil level depends on the mounting position:
Horizontal and vertical: Center of the sight glass1) For an inclined
mounting position: Mark on the angled oil level indicator
(additionally mount)
Oils which can be used: HLP 32 acc. to ISO–VG 68
Oil drain plugs: Provided at both sides
Circulating oil lubrication
Circulating oil lubrication is required for the following applications:
� for continuous operation
� for operation over a longer period of time in one gearbox stage
� for intermittent operation with short no–load intervals
The type of circulating oil lubrication depends on which operating temperature level
is required in use. Several applications require a low operating temperature level.
We recommend, in these cases, circulating oil lubrication. The oil intake quantity is
between 1 and 1.5 l/min with an oil pressure of approx. 1.5 bar. The diagrams 3-9
and 3-10 indicate the approximate oil intake and outlet positions on the gearbox.
The precise dimensions can be taken from the relevant mounting drawings.
For the following gearboxes, circulating oil lubrication is required for V1 or V3 vertical
mounting positions:
� Gearbox 2K120
� Gearbox 2K121
� Gearbox 2K250
� Gearbox 2K300
