To perform the spindle break-in:
1. Successfully complete the Test Run proce-
dure beginning on Page 21.
2. Set spindle direction switch to "F" (forward),
ensure range lever is in LOW, and operate
lathe for 10 minutes at 100 RPM.
3. Operate lathe at 1000 RPM for 10 minutes,
then turn variable speed dial to "0" to stop
spindle.
4. Shift range control lever to HIGH, then oper-
ate lathe at 2000 RPM for 10 minutes, then
stop spindle.
5. Run lathe in reverse at 2000 RPM for 10 min-
utes, then turn speed dial to "0", turn spindle
direction switch to "0", and press Emergency
Stop button.
Congratulations! Spindle break-in is complete.
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.

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 (Page 32).
• Cross slide backlash adjustment (Page 56).
• Gib adjustments (Page 57).
