LUBRIGATION Accuracy of the work produced and long, efficient service from your lathe depend to a large extent upon the care and correct attention given to lubrication. Oil levels Oil levels in the headstock and gearbox should be checked every week. When checking the levels atthe sight-glass, always stop the machine and allow a period of time for the oil to settle so that a true reading can be obtained. When this procedure is not followed there is a risk of overfilling which may result in the generation of excessive heat and cause oil loss through pressure leakage.
After an initial period of service of between 150 and 200 hours of running, both the headstock and gearbox of your new lathe should be drained, flushed with clean flushing oil and then refilled to the correctlevel with the recommended lubricant. Thereafter, repeat the draining and oil-change procedure every three months or 500 hours of operation-whichever is the shorter period. Periodic attention Before the new machine is put i4to service all oiling points should be properly lubricited, as indicated oi the Lubrication Chart which shows the attention recommended daily, weekly and monthly.
lt cannot be stressed too highly that all the oiling points marked with a black dot (bedway, leadscrew and spline shaft) should be carefully cleaned and lubricated every worki.ng day in order to obtain efficient opera- tion of the lathe. Before starting work each day run the machine at high speed for a few minutes in order to thoroughly distribute lubricant throughout the gearing. This procedure is also advised when a period of work at slow speeds is anticipated.

THE USE OF INCORRECT GRADES OF OIL IN THE HEADSTOCK AND GEARBOX IS LIABLE TO CAUSE OVERHEATING AND RESULT IN POSSIBLE DAMAGE. - Frrrm OtuCo:
