7. MAINTENANCE & ADJUSTMENT
7-1 Headstock
1. Headstock cover leaks:
When the headstock cover is removed it is important to re-install it properly
to prevent leakage. To re-install, the connecting surfaces must be cleaned
and coated with a thin layer of grease so it will seal properly.
2. There are three possible causes for oil to leak from the spindle covers.
1. Reservoir over filled. (Correction: drain oil to proper level).
2. Wrong weight oil. (Correction: Change to recommended lubricant)
3. Blocked oil return. (Correction: Remove the headstock cover and while
turning the spindle blow air through the small oil holes located in the
top of the head.
3. Spindle bearing adjustment:
The front and center bearings on the spindle are precision taper roller type.
To maintain the accuracy and proper operation, the bearings must have the
proper preload. To adjust the bearings loosen the set screws on locking nut
