the line.

the lever (2) on the valve is now locked in

S
Risk of damage to the angle gear!
If the drain tap remains open after changing the oil, the oil circuit will be
interrupted and the upper bearing will not be adequately supplied with oil.
This can lead to malfunctions and transmission damage.
The drain tap must always remain closed and secured with the lock during
driving and crane operation.
You only need to open the drain tap to drain the oil during an oil change.
After this, you must restore the normal operating condition by closing the
drain tap and securing it with the lock.
