G. LUBRICATION
To keep the machine in good order and prolong the life of the machine, it must be lubricated
with SAE 20 mechanical oil as per the lubrication instruction below.
Splash lubrication is used inside the headstock and cup-filling lubrication for other points.
To change the headstock oil, remove the oil and clean the inside of the headstock with a clean
cloth. Then fill with clean lubricating oil.
After the machining operation is finished, the surfaces of the slideways must be cleaned and
the swarf removed. The slides should then be covered with oil.
a. Recommend to use Grease #3 as listed in table of lubrication positions (Fig. 17)
b. Recommend to use Oil #20 as listed in the table of lubrication positions (Fig. 17)
c. Regularly, the lubricated parts should be cleaned and the oil in the feeding box should be
changed and refilled to the center line of the oil window.
