Mounting position MX
Mounting position MX is available for all gear units of the R..7, F..7, K..7, K..9, S..7 and
SPIROPLAN
®
W series.
For mounting position MX, the gear units are delivered with the maximally possible
amount of oil and sealed with oil screw plugs. A breather valve is included with each
drive. The customer will have to adjust the oil quantity to the proper level depending on
the final mounting position in which the gear unit will be operated. Customers will also
have to mount the enclosed breather valve at the proper location depending on the
mounting position, see mounting position sheets.
The correct oil level must be checked according to chapter "Checking the oil level and
changing the oil" (page 89).
7.4
Universal mounting position M0
SPIROPLAN
®
W10 – W30 gearmotors can be ordered with M0 universal mounting po-
sition as an option. Gear units with mounting position M0 are filled with the standard
amount of oil.
These gear units are entirely enclosed due to their small size. They can therefore be de-
signed without breather valve. Customers can use the gear unit universally in every
mounting position (M1 – M6) without having to take any measures prior to startup.
