before putting your mill into full operation.
Model G0727 (Mfg. Since 7/11)
Spindle Break-In
Before subjecting the mill to full loads, you must
break it in. This will allow the bearings and the
drive belt to fully seat and find their normal wear
pattern.

To help ensure long life and smooth opera-
tion, complete the spindle break-in before
placing the mill into full operation.
To perform the spindle break-in procedure:
1.
Successfully perform all the steps in the Test
Run section beginning on Page 16.
2.
Turn the spindle speed dial all the way coun-
terclockwise to the minimum speed, then
push the ON button to start the mill.
3.
Turn the spindle speed dial clockwise half-
way (to a medium speed) and let the mill run
for approximately 20 minutes.
4.
Turn the mill OFF—the spindle break-in is
now complete.
Lubrication & Gib
Before putting the mill into full operation, ensure
the table moves smoothly by performing the lubri-
cation procedures beginning on Page 27, and
inspecting the gib adjustments, as directed on
Page 32.
Besides ensuring smooth movement, these pro-
cedures will also prevent excessive wear of the
ways and leadscrews, and will protect against rust
or corrosion on the unpainted surfaces.
