4.3.2 Gearboxes with breathers
Stop!
Do not place gearbox onto breather valve!
The G50BS113 and G50BS122 gearboxes do not require any ventilation measures.
Gearboxes that are delivered with a ventilation unit are provided with a label.
Remove the transport locking device on the vent valve before initial commissioning.

Note!
Loosely enclosed vent valves must be mounted in accordance with the
mounting position, ( 43).
4.3.3 Gearbox with compensation container (preferably for mounting position
"C")
Temperature fluctuations generate changes in the lubricant volume. A compensation
reservoir serves to compensate for the change in volume in each case.
The compensation reservoir is supplied as a mounting set. Before commissioning, the
oil vent plug must be replaced with the reservoir.
Mounting and dismounting: mounting instructions for the compensation reservoir
Stop!
For transporting the geared motor, the compensation reservoir must be
removed and the gearbox must be locked by means of a locking screw.
Note!
With unfavourable combinations of a small ratio and a high input speed,
the use of a compensation reservoir may also be advisable in other
mounting positions.
