To perform spindle break-in:
1. Successfully complete Test Run procedure
beginning on Page 26.
2. Disengage half-nut lever and feed selection
lever.
3. Run spindle at 70 RPM for 10 minutes in
each direction (first forward, then reverse).
4. Repeat running lathe in this manner through
rest of spindle speeds, progressively increas-
ing in RPM to the highest speed.
5. Press EMERGENCY STOP button and
DISCONNECT LATHE FROM POWER!
Congratulations! Spindle break-in is complete.
Refer to Page 66 for lubrication information.
The following adjustments have been made at the
factory. However, because of the many variables
involved with shipping, we recommend you verify
these adjustments to ensure the best results:
Factory adjustments that should be verified:
• Tailstock alignment (see Page 39).
• Cross slide and compound slide backlash
adjustment (see Page 77).
• Gib adjustments (see Page 78).

Spindle Break-In
Before subjecting the spindle to operational loads,
it is essential to complete the break-in process.
This helps maximize the life of spindle bearings
and other precision components by thoroughly
lubricating them before placing them under load.
After spindle break-in is complete, we recommend
changing headstock and gearbox oil to remove
any metal particles or debris that are present from
the assembly and break-in process.
The break-in must be performed in succession
with the
Test Run procedure described in this
manual, as the steps in that procedure prepare
the lathe controls for the break-in process.
DO NOT perform this procedure indepen-
dently of the Test Run section. The lathe
could be seriously damaged if the controls
are set differently than instructed in that
section.
