All other gear units are delivered with a breather valve suitable to the mounting posi-
tion and activated.
Exceptions:
1. The following gear units are delivered with a screw plug on the provided breather
hole:
• Gear units with pivoted mounting positions, if possible
• Gear units for inclined mounting
Before startup, replace the highest screw plug in the terminal box of the motor with
the breather valve provided.
2. For
gear head units
venting on the input end, a breather valve is supplied in a
plastic bag.
3.
Enclosed gear units
are delivered without a breather valve.
4. In some countries, the breather valve is installed, but not activated due to possible
pressure fluctuations during transport. In such cases the transport protection must
be removed. This activates the breather valve (see chapter "Activating the breather
valve" (
Activating the breather valve
Check whether the breather valve is activated. If the breather valve has not been acti-
vated, you must remove the transport protection device from the breather valve before
starting up the gear unit!
