After a gear stage has been selected a limit switch (S1 or S2) sends a signal to the control to
switch off the selector unit.
5.4.7 Lubrication
Splash lubrication
Oil level check: Visually using a sight glass
The oil level depends on the mounting position:
horizontally and vertically: Middle of sight glass
1)
For an inclined mounting
position:
Mark on the angled oil level indicator (mount additionally)
Oils which can be used: HLP 32 acc. to ISO-VG 68
Oil drain bolts: on both sides
1) The oil volume data on the rating plate is only an approximate value
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 flow rate is between 1 and 1.5 l/min with an oil pressure of approx. 1.5 bar.
