Do not place gearbox onto breather valve!
For gearboxes of sizes 03, 04 and 0 5 (exception GSS 05), no ventilation measures are
required.
For gearboxes of sizes 06 to 14 and GSS 05, ventilation units are mounted. However, in
specific cases they may be dispensed with. For gearbox sizes 09 to 14 in mounting
position C we recommend using an oil compensation reservoir ( 52).
