Inspections &
Adjustments
The following adjustments were performed at the
factory before the machine was shipped:
• Gib Adjustments .............................
Page 38
• Leadscrew Backlash Adjustment ... Page 38
Be aware that these can change during the
shipping process. Pay careful attention to these
adjustments when first operating the machine. If
you find that the adjustments are not set to your
personal preferences, re-adjust them.
Spindle Bearing
Break-In
To perform spindle break-in procedure:
1. Use high/low range lever and variable-speed
dial to set spindle speed to 75 RPM (refer
to
Setting Spindle Speed on Page 29 for
detailed instructions).
2. Press STOP button, wait for spindle to com-
pletely stop, then run spindle for a minimum
of 5 minutes in reverse direction.
3. Repeat Steps 1–2 at spindle speeds of 1000
RPM and 2500 RPM.
4. Change headstock oil while it is still warm
(refer to Lubrication on Page 32 for detailed
instructions). This ensures you start opera-
tion with clean headstock oil.
The spindle break-in of the machine is now com-
plete!
The spindle break-in procedure distributes lubri-
cation throughout the bearings to reduce the risk
of early bearing failure if there are any "dry" spots
or areas where lubrication has settled in the bear-
ings. You
must complete this procedure before
placing operational loads on the spindle for the
first time when the machine is new or if it has
been sitting idle for longer than 6 months.
Always start the spindle break-in at the lowest
speed to minimize wear if there are dry spots.
Allow the spindle to run long enough to warm up
and distribute the bearing grease, then incremen-
tally increase spindle speeds, allowing the spindle
to run the same amount of time at each speed, until
reaching the maximum spindle speed. Following
the break-in procedure in this progressive man-
ner helps minimize any potential wear that could
occur until lubrication is fully distributed.
