5-2 Lubrication
When the machine is shipped, the bearings are filled with grease. The bearings should require
no lubrication for a month under usual operating conditions. If the machine is operated
continuously, it may be desirable to lubricate the machine every two or three weeks. This
machine should be lubricated with a high temperature bearing grease. We suggest Alemite
#38, Sun Oil #844, Sunoco Prestige 741EP, Sovarex #2, Shell EP Grease #1, Mobilux EP-2,
or Esso Multi-purpose Grease H.
