Model G0602/G0752 (Mfg. Since 11/12)
Before subjecting the lathe to full loads, it is essen-
tial to complete the spindle break-in process. This
will ensure the best results and maximum life of
the precision components inside the lathe.
The break-in procedure must be performed in
succession with the Test Run procedure because
many of the test run steps prepare the lathe con-
trols for the break-in process.
Important: Do not perform the break-in procedure
independently from the Test Run section—seri-
ous damage could occur to the lathe if the controls
are set differently than instructed in that section.
Spindle Break-In
To perform the spindle break-in:
1. Operate the lathe at 150 RPM for 10 minutes.
2. G0602: Repeat Step 1 at each of the following
speeds 300, 560, 720, 1200, and 2400.
G0752: Repeat Step 1 at each of the following
approximate speeds: 800, 1300, and 2000.
3. When the spindle has come to a complete
stop, run the spindle in reverse at 2400 RPM
(Model G0602) or 2000 RPM (Model G0752)
for another 10 minutes, then press the
emergency STOP button and DISCONNECT
THE LATHE FROM POWER!
4. Check, and if necessary, re-tension the drive
belts (refer to V-Belt Tension & Replacement
Page 64 on page for detailed instructions.)
5. While the oil is still warm and any metal par-
ticles are still suspended in the oil, change
the gearbox oil (refer to Lubrication on Page
52 for detailed instructions).
Congratulations! The spindle break-in is com-
plete. Continue with the following Recommended
