5.4 Pressure roller lubrication
The grinder has a pressure roller with tapered roller
bearings. These bearings should be checked for lubrication
every 1000 hours of operation or annually- whichever
comes first. These bearings should be checked for proper
adjustment daily.
5.5 Rotor bearing lubrication
As a general rule, rotor bearing oil should be replaced
every 500 hours of operation. However, if the oil becomes
discolored or milky in appearance, the oil should be replaced
immediately.
The static oil level should bring oil to the centerline of the
bottom roller. The oil level in the sight glass should be
centered in the sight glass.
When adding or replacing rotor bearing oil, use Mobil SHC-
626 oil or other similar oil, but never use a detergent motor
oil.
