The sliding velocity in feet per minute (FPM) for standard ratios is determined by multiplying the speed of the worm in RPM by the factor from
the following table. For selecting the proper lubricant, use the speed of the worm in the final stage (input RPM divided by the first stage ratio).

Factory filling - Speed reducers are filled with oil at the factory to the proper level for
the standard mounting position it will be found on the machine. The oil level should be
checked and adjusted (if necessary) before operation, using the oil level plug provided and
while the machine is oriented in its operating position.
Ambient temperature - If the operating ambient temperature is other than 51–95 °F,
refer to the lubrication chart and refill the machine with the correct grade based on actual
ambient temperature and operating speed. See "Oil changing" below for additional
information.
Oil changing - When changing the oil for any reason, it should be remembered that oils
of various types might not be compatible. Therefore, when changing to a different oil, it is
recommended that the housing be completely drained and thoroughly flushed with a light
flushing oil before refilling with the appropriate lubricant. The oil level should be rechecked
experience, recommends the use of Mobil SHC
synthetic lubricants.
