LUBRICATION
13. GENERAL: In the lubricati on of the machine the oil is metered, feeding oil in proper
amounts to all bearing surfaces. It is a one-way oiling action and when the reservoir supply
is
used, the machine must be refilled. The reservoir holds enough for forty hours of seaming .
14. Oil is
fill ed through a hole under the Cap Screw of the Oil Filler Assembly into the main
reservoir. About 8 ounces (0. 250 litres) of a high grade turbine oil of about 150 Sayboldt
seconds at 100° Fahrenheit (37. 5 °C) is recommended. To drain the oil, dismount the machine
and extend the feed mechanism end of the machine over the end of the table. After providing a
means of catching the oil, unscrew the Oil Drain Screw 11-3/ 8 (located at the rear of the
machine in the base) several turns.
