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 oil fill volume must be adapted according to the mounting position of the
gear unit. Customers will also have to mount the enclosed breather valve at the proper
location depending on the mounting position (see section "Mounting position
sheets (
Check for the correct oil level, as described in chapter "Oil level check and oil
change" (

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
oil quantity.
These gear units are entirely enclosed due to their small size and have no breather
valve. Customers can use the gear unit universally in every mounting position (M1 –
M6) without having to take any measures prior to startup.
